Evaluation of a web-based intervention to reduce antibiotic prescribing for LRTI in six European countries: quantitative process analysis of the GRACE/INTRO randomised controlled trial

Point-of-care testing and antibiotics prescribing in out-of-hours general practice: a register-based study in Denmark

BACKGROUND

Point-of-care testing may reduce diagnostic uncertainty in case of suspicion of bacterial infection, thereby contributing to prudent antibiotic prescribing. We aimed to study variations in the use of point-of-care tests (C-reactive protein test, rapid streptococcal antigen detection test, and urine dipstick) among general practitioners (GPs) and the potential association between point-of-care testing and antibiotic prescribing in out-of-hours general practice.

METHODS

We conducted a population-based observational register-based study, based on patient contacts with out-of-hours general practice in the Central Denmark Region in 2014-2017. The tendency of GPs to use point-of-care testing was calculated, and the association between the use of point-of-care testing and antibiotic prescribing was evaluated with the use of binomial regression.

RESULTS

Out-of-hours general practice conducted 794,220 clinic consultations from 2014 to 2017, of which 16.1% resulted in an antibiotic prescription. The GP variation in the use of point-of-care testing was largest for C-reactive protein tests, with an observed variation (p90/p10 ratio) of 3.0; this means that the GPs in the 90th percentile used C-reactive protein tests three times as often as the GPs in the 10th percentile. The observed variation was 2.1 for rapid streptococcal antigen detection tests and 1.9 for urine dipsticks. The GPs who tended to use more point-of-care tests prescribed significantly more antibiotics than the GPs who tended to use fewer point-of-care tests. The GPs in the upper quintile of the tendency to use C-reactive protein test prescribed 22% more antibiotics than the GPs in the lowest quintile (21% for rapid streptococcal antigen detection tests and 8% for urine dipsticks). Up through the quintiles, this effect exhibited a positive linear dose-response correlation.

CONCLUSION

The GPs varied in use of point-of-care testing. The GPs who tended to perform more point-of-care testing prescribed more antibiotics compared with the GPs who tended to perform fewer of these tests.

Performance evaluation of the LumiraDx quantitative microfluidic point-of-care CRP test

C-reactive protein (CRP) is an established acute-phase marker for infection, inflammation and tissue injury, used to guide clinical decision-making in primary and secondary care. This study compared the analytical performance of the quantitative microfluidic point-of-care LumiraDx CRP Test to a laboratory-based reference method (Siemens RCRP Flex assay on the Dimension® Xpand®) and evaluated equivalence of sample matrices (blood versus plasma) in point-of-care settings using samples from patients presenting with symptoms of infection or inflammation. The LumiraDx CRP Test demonstrated close agreement with the lab reference test (range, 5.1 to 245.2 mg/L, r = 0.992, slope = 0.998, intercept = -0.476; n = 205) and notable agreement between fingerstick and venous blood and plasma (r = 0.974-0.983; n = 44). Paired replicate precision had mean coefficients of variation of 6.4 % (plasma), 6.6 % (capillary direct) and 8.1 % (venous blood); overall error rates were 2.9 %. The quantitative LumiraDx CRP Test showed robust analytical performance across sample matrices and close agreement compared to the laboratory reference method when used at the point of care.

Effectiveness of analgesic ear drops as add-on treatment to oral analgesics in children with acute otitis media: study protocol of the OPTIMA pragmatic randomised controlled trial

INTRODUCTION

Ear pain is the most prominent symptom of childhood acute otitis media (AOM). To control the pain and reduce reliance on antibiotics, evidence of effectiveness for alternative interventions is urgently needed. This trial aims to investigate whether analgesic ear drops added to usual care provide superior ear pain relief over usual care alone in children presenting to primary care with AOM.

METHODS AND ANALYSIS

This is a pragmatic, two-arm, individually randomised, open, superiority trial with cost-effectiveness analysis and nested mixed-methods process evaluation in general practices in the Netherlands. We aim to recruit 300 children aged 1-6 years with a general practitioner (GP) diagnosis of AOM and ear pain. Children will be randomly allocated (ratio 1:1) to either (1) lidocaine hydrochloride 5 mg/g ear drops (Otalgan) one to two drops up to six times daily for a maximum of 7 days in addition to usual care (oral analgesics, with/without antibiotics); or (2) usual care. Parents will complete a symptom diary for 4 weeks as well as generic and disease-specific quality of life questionnaires at baseline and 4 weeks. The primary outcome is the parent-reported ear pain score (0-10) over the first 3 days. Secondary outcomes include proportion of children consuming antibiotics, oral analgesic use and overall symptom burden in the first 7 days; number of days with ear pain, number of GP reconsultations and subsequent antibiotic prescribing, adverse events, complications of AOM and cost-effectiveness during 4-week follow-up; generic and disease-specific quality of life at 4 weeks; parents' and GPs' views and experiences with treatment acceptability, usability and satisfaction.

ETHICS AND DISSEMINATION

The Medical Research Ethics Committee Utrecht, the Netherlands, has approved the protocol (21-447/G-D). All parents/guardians of participants will provide written informed consent. Study results will be submitted for publication in peer-reviewed medical journals and presented at relevant (inter)national scientific meetings.

TRIAL REGISTRATION

The Netherlands Trial Register: NL9500; date of registration: 28 May 2021. At the time of publication of the study protocol paper, we were unable to make any amendments to the trial registration record in the Netherlands Trial Register. The addition of a data sharing plan was required to adhere to the International Committee of Medical Journal Editors guidelines. The trial was therefore reregistered in ClinicalTrials.gov (NCT05651633; date of registration: 15 December 2022). This second registration is for modification purposes only and the Netherlands Trial Register record (NL9500) should be regarded as the primary trial registration.

Safety netting advice for respiratory tract infections in out-of-hours primary care: A qualitative analysis of consultation videos

BACKGROUND

General practitioners (GPs) use safety netting advice to communicate with patients when and how to seek further help when their condition fails to improve or deteriorate. Although many respiratory tract infections (RTI) during out-of-hours (OOH) care are self-limiting, often antibiotics are prescribed. Providing safety netting advice could enable GPs to safely withhold an antibiotic prescription by dealing both with their uncertainty and the patients' concerns.

OBJECTIVES

To explore how GPs use safety netting advice during consultations on RTIs in OOH primary care and how this advice is documented in the electronic health record.

METHODS

We analysed video observations of 77 consultations on RTIs from 19 GPs during OOH care using qualitative framework analysis and reviewed the medical records. Videos were collected from August until November 2018 at the Antwerp city GP cooperative, Belgium.

RESULTS

Safety netting advice on alarm symptoms, expected duration of illness and/or how and when to seek help is often lacking or vague. Communication of safety netting elements is scattered throughout the end phase of the consultation. The advice is seldom recorded in the medical health record. GPs give more safety netting advice when prescribing an antibiotic than when they do not prescribe an antibiotic.

CONCLUSION

We provided a better understanding of how safety netting is currently carried out in OOH primary care for RTIs. Safety netting advice during OOH primary care is limited, unspecific and not documented in the medical record.

Digital interventions for hypertension and asthma to support patient self-management in primary care: the DIPSS research programme including two RCTs

Background

Digital interventions offer a potentially cost-effective means to support patient self-management in primary care, but evidence for the feasibility, acceptability and cost-effectiveness of digital interventions remains mixed. This programme focused on the potential for self-management digital interventions to improve outcomes in two common, contrasting conditions (i.e. hypertension and asthma) for which care is currently suboptimal, leading to excess deaths, illness, disability and costs for the NHS.

Objectives

The overall purpose was to address the question of how digital interventions can best provide cost-effective support for patient self-management in primary care. Our aims were to develop and trial digital interventions to support patient self-management of hypertension and asthma. Through the process of planning, developing and evaluating these interventions, we also aimed to generate a better understanding of what features and methods for implementing digital interventions could make digital interventions acceptable, feasible, effective and cost-effective to integrate into primary care.

Design

For the hypertension strand, we carried out systematic reviews of quantitative and qualitative evidence, intervention planning, development and optimisation, and an unmasked randomised controlled trial comparing digital intervention with usual care, with a health economic analysis and nested process evaluation. For the asthma strand, we carried out a systematic review of quantitative evidence, intervention planning, development and optimisation, and a feasibility randomised controlled trial comparing digital intervention with usual care, with nested process evaluation.

Setting

General practices (hypertension, n = 76; asthma, n = 7) across Wessex and Thames Valley regions in Southern England.

Participants

For the hypertension strand, people with uncontrolled hypertension taking one, two or three antihypertensive medications. For the asthma strand, adults with asthma and impaired asthma-related quality of life.

Interventions

Our hypertension intervention (i.e. HOME BP) was a digital intervention that included motivational training for patients to self-monitor blood pressure, as well as health-care professionals to support self-management; a digital interface to send monthly readings to the health-care professional and to prompt planned medication changes when patients’ readings exceeded recommended targets for 2 consecutive months; and support for optional patient healthy behaviour change (e.g. healthy diet/weight loss, increased physical activity and reduced alcohol and salt consumption). The control group were provided with a Blood Pressure UK (London, UK) leaflet for hypertension and received routine hypertension care. Our asthma intervention (i.e. My Breathing Matters) was a digital intervention to improve the functional quality of life of primary care patients with asthma by supporting illness self-management. Motivational content intended to facilitate use of pharmacological self-management strategies (e.g. medication adherence and appropriate health-care service use) and non-pharmacological self-management strategies (e.g. breathing retraining, stress reduction and healthy behaviour change). The control group were given an Asthma UK (London, UK) information booklet on asthma self-management and received routine asthma care.

Main outcome measures

The primary outcome for the hypertension randomised controlled trial was difference between intervention and usual-care groups in mean systolic blood pressure (mmHg) at 12 months, adjusted for baseline blood pressure, blood pressure target (i.e. standard, diabetic or aged > 80 years), age and general practice. The primary outcome for the asthma feasibility study was the feasibility of the trial design, including recruitment, adherence, intervention engagement and retention at follow-up. Health-care utilisation data were collected via notes review.

Review methods

The quantitative reviews included a meta-analysis. The qualitative review comprised a meta-ethnography.

Results

A total of 622 hypertensive patients were recruited to the randomised controlled trial, and 552 (89%) were followed up at 12 months. Systolic blood pressure was significantly lower in the intervention group at 12 months, with a difference of –3.4 mmHg (95% confidence interval –6.1 to –0.8 mmHg), and this gave an incremental cost per unit of systolic blood pressure reduction of £11 (95% confidence interval £5 to £29). Owing to a cost difference of £402 and a quality-adjusted life-year (QALY) difference of 0.044, long-term modelling puts the incremental cost per QALY at just over £9000. The probability of being cost-effective was 66% at willingness to pay £20,000 per quality-adjusted life-year, and this was higher at higher thresholds. A total of 88 patients were recruited to the asthma feasibility trial (target n = 80; n = 44 in each arm). At 3-month follow-up, two patients withdrew and six patients did not complete outcome measures. At 12 months, two patients withdrew and four patients did not complete outcome measures. A total of 36 out of 44 patients in the intervention group engaged with My Breathing Matters [with a median of four (range 0–25) logins].

Limitations

Although the interventions were designed to be as accessible as was feasible, most trial participants were white and participants of lower socioeconomic status were less likely to take part and complete follow-up measures. Challenges remain in terms of integrating digital interventions with clinical records.

Conclusions

A digital intervention using self-monitored blood pressure to inform medication titration led to significantly lower blood pressure in participants than usual care. The observed reduction in blood pressure would be expected to lead to a reduction of 10–15% in patients suffering a stroke. The feasibility trial of My Breathing Matters suggests that a fully powered randomised controlled trial of the intervention is warranted. The theory-, evidence- and person-based approaches to intervention development refined through this programme enabled us to identify and address important contextual barriers to and facilitators of engagement with the interventions.

Future work

This research justifies consideration of further implementation of the hypertension intervention, a fully powered randomised controlled trial of the asthma intervention and wide dissemination of our methods for intervention development. Our interventions can also be adapted for a range of other health conditions.

Trial and study registration

The trials are registered as ISRCTN13790648 (hypertension) and ISRCTN15698435 (asthma). The studies are registered as PROSPERO CRD42013004773 (hypertension review) and PROSPERO CRD42014013455 (asthma review).

Let's Talk About Antibiotics: a randomised trial of two interventions to reduce antibiotic misuse

BACKGROUND

Children with acute respiratory tract infections (ARTIs) receive ≈11.4 million unnecessary antibiotic prescriptions annually. A noted contributor is inadequate parent-clinician communication, however, efforts to reduce overprescribing have only indirectly targeted communication or been impractical.

OBJECTIVES

Compare two feasible (higher vs lower intensity) interventions for enhancing parent-clinician communication on the rate of inappropriate antibiotic prescribing.

DESIGN

Multisite, parallel group, cluster randomised comparative effectiveness trial. Data collected between March 2017 and March 2019.

SETTING

Academic and private practice outpatient clinics.

PARTICIPANTS

Clinicians (n=41, 85% of eligible approached) and 1599 parent-child dyads (ages 1-5 years with ARTI symptoms, 71% of eligible approached).

INTERVENTIONS

All clinicians received 20 min ARTI diagnosis and treatment education. Higher intensity clinicians received an additional 50 min communication skills training. All parents viewed a 90 second antibiotic education video.

MAIN OUTCOMES AND MEASURES

Inappropriate antibiotic treatment was assessed via blinded medical record review by study clinicians and a priori defined as prescriptions for the wrong diagnosis or use of the wrong agent. Secondary outcomes were revisits, adverse drug reactions (both assessed 2 weeks after the visit) and parent ratings of provider communication, shared decision-making and visit satisfaction (assessed at end of the visit on Likert-type scales).

RESULTS

Most clinicians completed the study (n=38, 93%), were doctors (n=25, 66%), female (n=30, 78%) and averaged 8 years in practice. All parent-child dyad provided data for the main outcome (n=855 (54%) male, n=1043 (53%) <2 years). Inappropriate antibiotic prescribing was similar among patients who consulted with a higher intensity (54/696, 7.8%) versus a lower intensity (85/904, 9.4%) clinician. A generalised linear mixed effect regression model (adjusted for the two-stage nested design, clinician type, clinic setting and clinician experience) revealed that the odds of receiving inappropriate antibiotic treatment did not significantly vary by group (AOR 0.99, 95% CI: 0.52 to 1.89, p=0.98). Secondary outcomes of revisits and adverse reactions did not vary between arms, and parent ratings of satisfaction with quality of parent-provider communication (5/5), shared decision making (9/10) and visit satisfaction (5/5) were similarly high in both arms.

CONCLUSIONS AND RELEVANCE

Rate of inappropriate prescribing was low in both arms. Clinician education coupled with parent education may be sufficient to yield low inappropriate antibiotic prescribing rates. The absence of a significant difference between groups indicates that communication principles previously thought to drive inappropriate prescribing may need to be re-examined or may not have as much of an impact in practices where prescribing has improved in recent years.

Nationwide implementation of online communication skills training to reduce overprescribing of antibiotics: a stepped-wedge cluster randomized trial in general practice

Objectives

Primary care is responsible for a large proportion of unnecessary antibiotic use, which is one of the main drivers of antibiotic resistance. Randomized trials have found that online communication skills training for GPs reduces antibiotic prescribing for respiratory infections. This study assesses the real-world effect of implementing online communication skills training in general practice.

Methods

In a closed cohort stepped-wedge cluster randomized trial all Belgian GPs were invited to participate in online communication skills training courses (TRACE and INTRO) and provided with linked patient information booklets. The primary outcome was the antibiotic prescribing rate per 1000 patient contacts. Intention-to-treat and per protocol analyses were performed. Trial registration at ClinicalTrials.gov: NCT03265028.

Results

In total, 118 487 observations from 10 375 GPs were included in the analysis. Overall, 299 (2.88%) GPs completed TRACE and 93 (0.90%) completed INTRO, 30 of which completed both. There was no effect of the national implementation of TRACE and INTRO on the population-level antibiotic prescribing rate (prescribing rate ratio [PRR] = 0.99 [95% CI: 0.97–1.02]). GPs who actually completed TRACE prescribed fewer antibiotic prescriptions (PRR = 0.93 [95% CI: 0.90–0.95]).

Conclusions

Inviting GPs to complete an online communication skills training course and providing them with the linked patient information booklets did not reduce antibiotic prescribing. However, GPs who completed TRACE prescribed 7% fewer antibiotics, especially during winter. This suggests a significant decrease in population-wide antibiotic consumption could be achieved by focusing on increasing the uptake of this intervention by identifying and overcoming barriers to participation.

Perceptions of primary health care physicians about the prescription of antibiotics in Saudi Arabia: Based on the model of Theory of planned behaviour

Introduction

Knowledge of different factors that influence physician decision-making in general practice for prescribing antibiotics is vital for successfully implementing antimicrobial stewardship interventions. The Theory of planned behaviour (TPB) is an established model that describes how cognitions drive human behaviour.

Objectives

The present study was performed to identify the socio-cultural and behavioural determinants that affect antibiotics prescription behaviour among primary care physicians and estimate the awareness about antibiotic resistance of public health importance.

Methodology

The questionnaire was divided into three sections: Section-I, which contained demographic content. Section-II contained 21 question items measuring attitudes, subjective norms, perceived behavioural control, and behavioural intentions of the prescribers. Section III had 12 questions related to knowledge about antibiotic resistance. As determined by Cronbach's α for each set of measured constructs of questionnaire scale, the internal consistency was good (α ≥ 0.7). The participants' socio-cultural and behavioural determinants were graded in 3 categories depending upon the mean score, while frequencies were used to estimate antibiotic resistance awareness. The data was analyzed by calculating the one-way ANOVA and by post-hoc Tukey-Kramer HSD multiple comparison test.

Results

Four hundred thirty-four primary health care physicians responded to the questionnaire, and data was statistically investigated. Participants' knowledge of antibiotic-resistant bacteria was poor with greater behavioural intentions to prescribe antibiotics, but a positive attitude and acceptable perceived social pressure towards antibiotics.

Conclusion

Our study showed that awareness towards antibiotic-resistant bacteria among primary care physicians of Saudi Arabia stands insufficient but favourable attitude and satisfactory social pressure towards antibiotics with greater behavioural intentions to prescribe antibiotics. The continued medical education (CME) and frequent training interventions can increase these parameters of rational prescribing practice for antibiotics.

OUP accepted manuscript

Antibiotic use (and misuse) accelerates antimicrobial resistance (AMR), and addressing this complex problem necessitates behaviour change related to infection prevention and management and to antibiotic prescribing and use. As most antibiotic courses are prescribed in primary care, a key focus of antimicrobial stewardship (AMS) is on changing behaviours outside of hospital. Behavioural science draws on behaviour change theories, techniques and methods developed in health psychology, and can be used to help understand and change behaviours related to AMR/AMS. Qualitative methodologies can be used together with a behavioural science approach to explore influences on behaviour and develop and evaluate behavioural interventions. This paper provides an overview of how the behavioural science approach, together with qualitative methods, can contribute and add value to AMS projects. First, it introduces and explains the relevance of the behavioural science approach to AMR/AMS. Second, it provides an overview of behaviour change ‘tools’: behaviour change theories/models, behavioural determinants and behaviour change techniques. Third, it explains how behavioural methods can be used to: (i) define a clinical problem in behavioural terms and identify behavioural influences; (ii) develop and implement behavioural AMS interventions; and (iii) evaluate them. These are illustrated with examples of using qualitative methods in AMS studies in primary care. Finally, the paper concludes by summarizing the main contributions of taking the behavioural science approach to qualitative AMS research in primary care and discussing the key implications and future directions for research and practice.

Development of an intervention to support the implementation of evidence-based strategies for optimising antibiotic prescribing in general practice

Background

Trials show that antimicrobial stewardship (AMS) strategies, including communication skills training, point-of-care C-reactive protein testing (POC-CRPT) and delayed prescriptions, help optimise antibiotic prescribing and use in primary care. However, the use of these strategies in general practice is limited and inconsistent. We aimed to develop an intervention to enhance uptake and implementation of these strategies in primary care.

Methods

We drew on the Person-Based Approach to develop an implementation intervention in two stages. (1) Planning and design: We defined the problem in behavioural terms drawing on existing literature and conducting primary qualitative research (nine focus groups) in high-prescribing general practices. We identified ‘guiding principles’ with intervention objectives and key features and developed logic models representing intended mechanisms of action. (2) Developing the intervention: We created prototype intervention materials and discussed and refined these with input from 13 health professionals and 14 citizens in two sets of design workshops. We further refined the intervention materials following think-aloud interviews with 22 health professionals.

Results

Focus groups highlighted uncertainties about how strategies could be used. Health professionals in the workshops suggested having practice champions, brief summaries of each AMS strategy and evidence supporting the AMS strategies, and they and citizens gave examples of helpful communication strategies/phrases. Think-aloud interviews helped clarify and shorten the text and user journey of the intervention materials. The intervention comprised components to support practice-level implementation: antibiotic champions, practice meetings with slides provided, and an ‘implementation support’ website section, and components to support individual-level uptake: website sections on each AMS strategy (with evidence, instructions, links to electronic resources) and material resources (patient leaflets, POC-CRPT equipment, clinician handouts).

Conclusions

We used a systematic, user-focussed process of developing a behavioural intervention, illustrating how it can be used in an implementation context. This resulted in a multicomponent intervention to facilitate practice-wide implementation of evidence-based strategies which now requires implementing and evaluating. Focusing on supporting the uptake and implementation of evidence-based strategies to optimise antibiotic use in general practice is critical to further support appropriate antibiotic use and mitigate antimicrobial resistance.

The use of theory in process evaluations conducted alongside randomized trials of implementation interventions: A systematic review

Interventions to implement changes into health care practice (i.e., implementation interventions) are critical to improving care but their effects are poorly understood. Two strategies to better understand intervention effects are conducting process evaluations and using theoretical approaches (i.e., theories, models, frameworks). The extent to which theoretical approaches have been used in process evaluations conducted alongside trials of implementation interventions is unclear. In this study context, we reviewed (a) the proportion of process evaluations citing theoretical approaches, (b) which theoretical approaches were cited, and (c) whether and how theories were used. Systematic review (PROSPERO: CRD42016042789). MEDLINE, PsycINFO, Embase, CINAHL, and Cochrane CENTRAL were searched up to July 31, 2017. For all studies, data extraction included names and types of theoretical approaches cited. For studies citing a theory, data extraction included study characteristics and extent of theory use (i.e., "informed by," "applied," "tested," "built/created" theory). We identified 123 process evaluations. Key findings: (a) 77 (63%) process evaluations cited a theoretical approach; (b) the most cited theory was normalization process theory; (c) 32 (26%) process evaluations used theory: 7 (22%) were informed by, 18 (56%) applied, 7 (22%) tested, and none built/created theory. Although nearly two thirds of process evaluations cited a theoretical approach, only a quarter were informed by, applied, or tested a theory-despite the potential complementarity of these strategies. When theory was used, it was primarily applied. Using theory more substantively in process evaluations may accelerate our understanding of how implementation interventions operate.

Safety of reducing antibiotic prescribing in primary care: a mixed-methods study

Background

The threat of antimicrobial resistance has led to intensified efforts to reduce antibiotic utilisation, but serious bacterial infections are increasing in frequency.

Objectives

To estimate the risks of serious bacterial infections in association with lower antibiotic prescribing and understand stakeholder views with respect to safe antibiotic reduction.

Design

Mixed-methods research was undertaken, including a qualitative interview study of patient and prescriber views that informed a cohort study and a decision-analytic model, using primary care electronic health records. These three work packages were used to design an application (app) for primary care prescribers.

Data sources

The Clinical Practice Research Datalink.

Setting

This took place in UK general practices.

Participants

A total of 706 general practices with 66.2 million person-years of follow-up from 2002 to 2017 and antibiotic utilisation evaluated for 671,830 registered patients. The qualitative study included 31 patients and 30 health-care professionals from primary care.

Main outcome measures

Sepsis and localised bacterial infections.

Results

Patients were concerned about antimicrobial resistance and the side effects, as well as the benefits, of antibiotic treatment. Prescribers viewed the onset of sepsis as the most concerning potential outcome of reduced antibiotic prescribing. More than 40% of antibiotic prescriptions in primary care had no coded indication recorded across both Vision® and EMIS® practice systems. Antibiotic prescribing rates varied widely between general practices, but there was no evidence that serious bacterial infections were less frequent at higher prescribing practices (adjusted rate ratio for 20% increase in prescribing 1.03, 95% confidence interval 1.00 to 1.06; p = 0.074). The probability of sepsis was lower if an antibiotic was prescribed at an infection consultation, and the number of antibiotic prescriptions required to prevent one episode of sepsis (i.e. the number needed to treat) decreased with age. For those aged 0–4 years, the number needed to treat was 29,773 (95% uncertainty interval 18,458 to 71,091) in boys and 27,014 (95% uncertainty interval 16,739 to 65,709) in girls. For those aged > 85 years, the number needed to treat was 262 (95% uncertainty interval 236 to 293) in men and 385 (95% uncertainty interval 352 to 421) in women. Frailty was associated with a greater risk of sepsis and a smaller number needed to treat. For severely frail patients aged 55–64 years, the number needed to treat was 247 (95% uncertainty interval 156 to 459) for men and 343 (95% uncertainty interval 234 to 556) for women. At all ages, the probability of sepsis was greatest for urinary tract infection, followed by skin infection and respiratory tract infection. The numbers needed to treat were generally smaller for the period 2014–17, when sepsis was diagnosed more frequently. The results are available using an app that we developed to provide primary care prescribers with stratified risk estimates during infection consultations.

Limitations

Analyses were based on non-randomised comparisons. Infection episodes and antibiotic prescribing are poorly documented in primary care.

Conclusions

Antibiotic treatment is generally associated with lower risks, but the most serious bacterial infections remain infrequent even without antibiotic treatment. This research identifies risk strata in which antibiotic prescribing can be more safely reduced.

Future work

The software developed from this research may be further developed and investigated for antimicrobial stewardship effect.

Care Starts at Home: Emotional State and Appeals to Altruism may Reduce Demand for Overused Health Services in the UK

BACKGROUND

Overuse of unnecessary services, screening tests, and treatments is an ongoing problem for national health care systems. Overuse is at least partly driven by patient demand.

PURPOSE

This study examined whether altering patients' emotional state and appealing to patient altruism would reduce demand for three commonly overused UK health services.

METHODS

In an online experiment, 1,267 UK volunteers were randomized to anxiety, compassion, or neutral conditions before viewing three overuse vignettes. In each vignette, use of the health service was recommended against by the doctor and participants were further randomized to one of three altruism frames, emphasizing the impact of overuse on the self, the self and others locally, or the self and others nationally. Participants rated the likelihood that they would pursue the health service and, assuming that they did not, how long they would be willing-to-wait for it.

RESULTS

Altruism frame had a small effect on intentions to use the health service. Those in the local or national (vs. self) frame were 4.7 and 6.1 percentage points, respectively, less likely to ask for the service. Emotion induction had no direct effect on outcomes. However, self-reporting higher levels of anxiety or compassion post-induction was associated with a small, greater likelihood in intentions to ask for the health service or willingness-to-wait, respectively. No interactions between frame and emotion were observed.

CONCLUSIONS

As a low-cost initiative, emphasizing the benefits to the self and local or national communities could be embedded in appeals designed to appropriately reduce health care overuse in the UK.

Patient engagement with antibiotic messaging in secondary care: a qualitative feasibility study of the ‘review and revise’ experience

Background

We aimed to investigate and optimise the acceptability and usefulness of a patient leaflet about antibiotic prescribing decisions made during hospitalisation, and to explore individual patient experiences and preferences regarding the process of antibiotic prescription ‘review and revise’ which is a key strategy to minimise antibiotic overuse in hospitals.

Methods

In this qualitative study, run within the feasibility study of a large, cluster-randomised stepped wedge trial of 36 hospital organisations, a series of semi-structured, think-aloud telephone interviews were conducted and data were analysed using thematic analysis. Fifteen adult patients who had experienced a recent acute medical hospital admission during which they had been prescribed antimicrobials and offered a patient leaflet about antibiotic prescribing were recruited to the study.

Results

Participants reacted positively to the leaflet, reporting that it was both an accessible and important source of information which struck the appropriate balance between informing and reassuring. Participants all valued open communication with clinicians, and were keen to be involved in antibiotic prescribing decisions, with individuals reporting positive experiences regarding antibiotic prescription changes or stopping. Many participants had prior experience or knowledge of antibiotics and resistance, and generally welcomed efforts to reduce antibiotic usage. Overall, there was a feeling that healthcare professionals (HCPs) are trusted experts providing the most appropriate treatment for individual patient conditions.

Conclusions

This study offers novel insights into how patients within secondary care are likely to respond to messages advocating a reduction in the use of antibiotics through the ‘review and revise’ approach. Due to the level of trust that patients place in their care provider, encouraging HCPs within secondary care to engage patients with greater communication and information provision could provide great advantages in the drive to reduce antibiotic use. It may also be beneficial for HCPs to view patient experiences as cumulative events that have the potential to impact future behaviour around antibiotic use. Finally, pre-testing messages about antibiotic prescribing and resistance is vital to dispelling any misconceptions either around effectiveness of treatment for patients, or perceptions of how messages may be received.

Risks of use and non-use of antibiotics in primary care: qualitative study of prescribers' views

PURPOSE

The emergence of antimicrobial resistance has led to increasing efforts to reduce unnecessary use of antibiotics in primary care, but potential hazards from bacterial infection continue to cause concern. This study investigated how primary care prescribers perceive risk and safety concerns associated with reduced antibiotic prescribing.

METHODS

Qualitative study using semistructured interviews conducted with primary care prescribers from 10 general practices in an urban area and a shire town in England. A thematic analysis was conducted.

RESULTS

Thirty participants were recruited, including twenty-three general practitioners, five nurses and two pharmacists. Three main themes were identified: risk assessment, balancing treatment risks and negotiating decisions and risks. Respondents indicated that their decisions were grounded in clinical risk assessment, but this was informed by different approaches to antibiotic use, with most leaning towards reduced prescribing. Prescribers' perceptions of risk included the consequences of both inappropriate prescribing and inappropriate withholding of antibiotics. Sepsis was viewed as the most concerning potential outcome of non-prescribing, leading to possible patient harm and potential litigation. Risks of antibiotic prescribing included antibiotic resistant and Clostridium difficile infections, as well as side effects, such as rashes, that might lead to possible mislabelling as antibiotic allergy. Prescribers elicited patient preferences for use or avoidance of antibiotics to inform management strategies, which included educational advice, advice on self-management including warning signs, use of delayed prescriptions and safety netting.

CONCLUSIONS

Attitudes towards antibiotic prescribing are evolving, with reduced antibiotic prescribing now being approached more systematically. The safety trade-offs associated with either use or non-use of antibiotics present difficulties especially when prescribing decisions are inconsistent with patients' expectations.

Point-of-Care C-Reactive Protein Testing to Reduce Antibiotic Prescribing for Respiratory Tract Infections in Primary Care: Systematic Review and Meta-Analysis of Randomised Controlled Trials

C-reactive protein (CRP) point-of-care testing (POCT) is increasingly being promoted to reduce diagnostic uncertainty and enhance antibiotic stewardship. In primary care, respiratory tract infections (RTIs) are the most common reason for inappropriate antibiotic prescribing, which is a major driver for antibiotic resistance. We systematically reviewed the available evidence on the impact of CRP-POCT on antibiotic prescribing for RTIs in primary care. Thirteen moderate to high-quality studies comprising 9844 participants met our inclusion criteria. Meta-analyses showed that CRP-POCT significantly reduced immediate antibiotic prescribing at the index consultation compared with usual care (RR 0.79, 95%CI 0.70 to 0.90, p = 0.0003, I² = 76%) but not during 28-day (n = 7) follow-up. The immediate effect was sustained at 12 months (n = 1). In children, CRP-POCT reduced antibiotic prescribing when CRP (cut-off) guidance was provided (n = 2). Meta-analyses showed significantly higher rates of re-consultation within 30 days (n = 8, 1 significant). Clinical recovery, resolution of symptoms, and hospital admissions were not significantly different between CRP-POCT and usual care. CRP-POCT can reduce immediate antibiotic prescribing for RTIs in primary care (number needed to (NNT) for benefit = 8) at the expense of increased re-consultations (NNT for harm = 27). The increase in re-consultations and longer-term effects of CRP-POCT need further evaluation. Overall, the benefits of CRP-POCT outweigh the potential harms (NNTnet = 11).

Intervention planning for Antibiotic Review Kit (ARK): a digital and behavioural intervention to safely review and reduce antibiotic prescriptions in acute and general medicine

Background

Hospital antimicrobial stewardship strategies, such as ‘Start Smart, Then Focus’ in the UK, balance the need for prompt, effective antibiotic treatment with the need to limit antibiotic overuse using ‘review and revise’. However, only a minority of review decisions are to stop antibiotics. Research suggests that this is due to both behavioural and organizational factors.

Objectives

To develop and optimize the Antibiotic Review Kit (ARK) intervention. ARK is a complex digital, organizational and behavioural intervention that supports implementation of ‘review and revise’ to help healthcare professionals safely stop unnecessary antibiotics.

Methods

A theory-, evidence- and person-based approach was used to develop and optimize ARK and its implementation. This was done through iterative stakeholder consultation and in-depth qualitative research with doctors, nurses and pharmacists in UK hospitals. Barriers to and facilitators of the intervention and its implementation, and ways to address them, were identified and then used to inform the intervention’s development.

Results

A key barrier to stopping antibiotics was reportedly a lack of information about the original prescriber’s rationale for and their degree of certainty about the need for antibiotics. An integral component of ARK was the development and optimization of a Decision Aid and its implementation to increase transparency around initial prescribing decisions.

Conclusions

The key output of this research is a digital and behavioural intervention targeting important barriers to stopping antibiotics at review (see http://bsac-vle.com/ark-the-antibiotic-review-kit/ and http://antibioticreviewkit.org.uk/). ARK will be evaluated in a feasibility study and, if successful, a stepped-wedge cluster-randomized controlled trial at acute hospitals across the NHS.

Novel education-based intervention to reduce inappropriate antibiotic prescribing for treatment of gonorrhoea in China: protocol for a cluster randomised controlled trial

INTRODUCTION

Inappropriate use of antibiotics to treat gonorrhoea can lead to antibiotic resistance. Education programmes may be helpful for improving physician prescribing behaviours in accordance with treatment guidelines. As traditional education based on printed materials may have limited effect on guideline-based treatment, innovative education strategies are needed. The current trial aims to assess the effectiveness of a novel education intervention to increase guideline-based treatment of gonorrhoea in China.

METHODS AND ANALYSIS

We will conduct a two-arm cluster randomised control trial at 144 hospitals (clusters) in eight Chinese provinces. The intervention will include an online training video developed on the WenJuanXing platform that covers workflows and requirements for managing a patient with uncomplicated gonorrhoea. Outpatient physicians in dermatology (dermatovenerology), urology, andrology and gynaecology will be given access to the video via a quick response code. In hospitals allocated to the control arm, physicians will continue to participate in their standard of care training programme. The primary outcome is the proportion of gonorrhoea antibiotic prescriptions adherent to Chinese national guidelines at the cluster level. In addition, to understand the reasons of physician's non-adherence to the intervention by conducting a questionnaire survey will be considered as the secondary outcome of the study.

ETHICS AND DISSEMINATION

Ethical approval was obtained from the Medical Ethics Committee of the Chinese Academy of Medical Sciences Institute of Dermatology (2020-LS-004). All physicians will provide an informed consent prior to participating in the study. Findings of the trial will be disseminated through conferences and peer-reviewed journals, and will be used to develop training programmes for physicians.

FDA collaboration to improve safe use of fluoroquinolone antibiotics: an ex post facto matched control study of targeted short-form messaging and online education served to high prescribers

Objective:

This ex post facto matched control study was conducted to evaluate the effect of targeted short-form messages or continuing medical education (CME) on fluoroquinolone prescribing among high prescribers.

Methods:

A total of 11,774 Medscape healthcare provider (HCP) members prescribing high volumes of fluoroquinolones were randomized into three segments to receive one of three unique targeted short-form messages, each delivered via email, web alerts, and mobile alerts. Some HCPs receiving targeted short-form messages also participated in CME on fluoroquinolone prescribing. A fourth segment of HCPs participated in CME only. Test HCPs were matched to third-party-provider prescriber data to identify control HCPs. We used prescriber data to determine new prescription volume; percentage (%) of HCPs with reduced prescribing; new prescription volume for acute bacterial sinusitis (ABS), uncomplicated urinary tract infection (uUTI), and acute bacterial exacerbations of chronic bronchitis in those with chronic obstructive pulmonary disease (ABECB-COPD). Open rates for emailed targeted short-form messages were also measured.

Results:

Targeted short-form messages and CME each resulted in significant new prescription volume reduction versus control. Combining targeted short-form messages with CME yielded the greatest percentage of test HCPs with reduced prescribing (80.1%) versus controls (76.2%; p<0.0001). New prescription volume decreased significantly for uUTI and ABS following exposure to targeted short-form messages, CME, or both. Targeted short-form messages containing comparative prescribing information with or without clinical context were opened at slightly higher rates (10.8% and 10.6%, respectively) than targeted short-form messages containing clinical context alone (9.1%).

Conclusions:

Targeted short-form messages and CME, alone and in combination, are associated with reduced oral fluoroquinolone prescribing among high prescribers.

Health Professions Digital Education on Antibiotic Management: Systematic Review and Meta-Analysis by the Digital Health Education Collaboration

BACKGROUND

Inappropriate antibiotic prescription is one of the key contributors to antibiotic resistance, which is managed with a range of interventions including education.

OBJECTIVE

We aimed to summarize evidence on the effectiveness of digital education of antibiotic management compared to traditional education for improving health care professionals' knowledge, skills, attitudes, and clinical practice.

METHODS

Seven electronic databases and two trial registries were searched for randomized controlled trials (RCTs) and cluster RCTs published between January 1, 1990, and September 20, 2018. There were no language restrictions. We also searched the International Clinical Trials Registry Platform Search Portal and metaRegister of Controlled Trials to identify unpublished trials and checked the reference lists of included studies and relevant systematic reviews for study eligibility. We followed Cochrane methods to select studies, extract data, and appraise and synthesize eligible studies. We used random-effect models for the pooled analysis and assessed statistical heterogeneity by visual inspection of a forest plot and calculation of the I² statistic.

RESULTS

Six cluster RCTs and two RCTs with 655 primary care practices, 1392 primary care physicians, and 485,632 patients were included. The interventions included personal digital assistants; short text messages; online digital education including emails and websites; and online blended education, which used a combination of online digital education and traditional education materials. The control groups received traditional education. Six studies assessed postintervention change in clinical practice. The majority of the studies (4/6) reported greater reduction in antibiotic prescription or dispensing rate with digital education than with traditional education. Two studies showed significant differences in postintervention knowledge scores in favor of mobile education over traditional education (standardized mean difference=1.09, 95% CI 0.90-1.28; I²=0%; large effect size; 491 participants [2 studies]). The findings for health care professionals' attitudes and patient-related outcomes were mixed or inconclusive. Three studies found digital education to be more cost-effective than traditional education. None of the included studies reported on skills, satisfaction, or potential adverse effects.

CONCLUSIONS

Findings from studies deploying mobile or online modalities of digital education on antibiotic management were complementary and found to be more cost-effective than traditional education in improving clinical practice and postintervention knowledge, particularly in postregistration settings. There is a lack of evidence on the effectiveness of other digital education modalities such as virtual reality or serious games. Future studies should also include health care professionals working in settings other than primary care and low- and middle-income countries.

Digital Learning to Improve Safe and Effective Prescribing: A Systematic Review

With the aim to modernize and harmonize prescribing education, the European Association for Clinical Pharmacology and Therapeutics (EACPT) Working Group on education recommended the extensive use and distribution of digital learning resources (DLRs). However, it is unclear whether the complex task of prescribing medicine can be taught digitally. Therefore, the aim of this review was to investigate the effect of diverse DLRs in clinical pharmacology and therapeutics education. Databases PubMed, EMBASE, CINAHL, ERIC, and CENTRAL were systematically searched. Sixty-five articles were included in the analyses. Direct effects on patients were studied, but not detected, in six articles. Skills and behavior were studied in 11 articles, 8 of which reported positive effects. Knowledge acquisition was investigated in 19 articles, all with positive effects. Qualitative analyses yielded 10 recommendations for the future development of DLRs. Digital learning is effective in teaching knowledge, attitudes, and skills associated with safe and effective prescribing.

Effectiveness of general practitioner online training and an information booklet for parents on antibiotic prescribing for children with respiratory tract infection in primary care: a cluster randomized controlled trial

Objectives

Antibiotics are too often prescribed in childhood respiratory tract infection (RTI), despite limited effectiveness, potential side effects and bacterial resistance. We aimed to reduce antibiotic prescribing for children with RTI by online training for general practitioners (GPs) and information for parents.

Methods

A pragmatic cluster randomized controlled trial in primary care. The intervention consisted of online training for GPs and an information booklet for parents. The primary outcome was the antibiotic prescription rate for children presenting with RTI symptoms, as registered by GPs. Secondary outcomes were number of reconsultations within the same disease episode, consultations for new episodes, hospital referrals and pharmacy-dispensed antibiotic courses for children. This trial was registered at the Dutch Trial Register (NTR), registration number: NTR4240.

Results

After randomization, GPs from a total of 32 general practices registered 1009 consultations. An antibiotic was prescribed in 21% of consultations in the intervention group, compared with 33% in the usual care group, controlled for baseline prescribing (rate ratio 0.65, 95% CI 0.46-0.91). The probability of reconsulting during the same RTI episode did not differ significantly between the intervention and control groups, and nor did the numbers of consultations for new episodes and hospital referrals. In the intervention group antibiotic dispensing was 32 courses per 1000 children/year lower than the control group, adjusted for baseline prescribing (rate ratio 0.78, 95% CI 0.66-0.92). The numbers and proportion of second-choice antibiotics did not differ significantly.

Conclusions

Concise, feasible, online GP training, with an information booklet for parents, showed a relevant reduction in antibiotic prescribing for children with RTI.

Antibiotic Prescribing for Acute Respiratory Tract Infections 12 Months After Communication and CRP Training: A Randomized Trial

PURPOSE

C-reactive-protein (CRP) is useful for diagnosis of lower respiratory tract infections (RTIs). A large international trial documented that Internet-based training in CRP point-of-care testing, in enhanced communication skills, or both reduced antibiotic prescribing at 3 months, with risk ratios (RRs) of 0.68, 0.53, 0.38, respectively. We report the longer-term impact in this trial.

METHODS

A total of 246 general practices in 6 countries were cluster-randomized to usual care, Internet-based training on CRP point-of-care testing, Internet-based training on enhanced communication skills and interactive booklet, or both interventions combined. The main outcome was antibiotic prescribing for RTIs after 12 months.

RESULTS

Of 228 practices providing 3-month data, 74% provided 12-month data, with no demonstrable attrition bias. Between 3 months and 12 months, prescribing for RTIs decreased with usual care (from 58% to 51%), but increased with CRP training (from 35% to 43%) and with both interventions combined (from 32% to 45%); at 12 months, the adjusted RRs compared with usual care were 0.75 (95% CI, 0.51-1.00) and 0.70 (95% CI, 0.49-0.93), respectively. Between 3 months and 12 months, the reduction in prescribing with communication training was maintained (41% and 40%, with an RR at 12 months of 0.70 [95% CI, 0.49-0.94]). Although materials were provided for free, clinicians seldom used booklets and rarely used CRP point-of-care testing. Communication training, but not CRP training, remained efficacious for reducing prescribing for lower RTIs (RR = 0.7195% CI, 0.45-0.99, and RR = 0.76; 95% CI, 0.47-1.06, respectively), whereas both remained efficacious for reducing prescribing for upper RTIs (RR = 0.60; 95% CI, 0.37-0.94, and RR = 0.58; 95% CI, 0.36-0.92, respectively).

CONCLUSIONS

Internet-based training in enhanced communication skills remains effective in the longer term for reducing antibiotic prescribing. The early improvement seen with CRP training wanes, and this training becomes ineffective for lower RTIs, the only current indication for using CRP testing.

Online Digital Education for Postregistration Training of Medical Doctors: Systematic Review by the Digital Health Education Collaboration

Background

Globally, online and local area network–based (LAN) digital education (ODE) has grown in popularity. Blended learning is used by ODE along with traditional learning. Studies have shown the increasing potential of these technologies in training medical doctors; however, the evidence for its effectiveness and cost-effectiveness is unclear.

Objective

This systematic review evaluated the effectiveness of online and LAN-based ODE in improving practicing medical doctors’ knowledge, skills, attitude, satisfaction (primary outcomes), practice or behavior change, patient outcomes, and cost-effectiveness (secondary outcomes).

Methods

We searched seven electronic databased for randomized controlled trials, cluster-randomized trials, and quasi-randomized trials from January 1990 to March 2017. Two review authors independently extracted data and assessed the risk of bias. We have presented the findings narratively. We mainly compared ODE with self-directed/face-to-face learning and blended learning with self-directed/face-to-face learning.

Results

A total of 93 studies (N=16,895) were included, of which 76 compared ODE (including blended) and self-directed/face-to-face learning. Overall, the effect of ODE (including blended) on postintervention knowledge, skills, attitude, satisfaction, practice or behavior change, and patient outcomes was inconsistent and ranged mostly from no difference between the groups to higher postintervention score in the intervention group (small to large effect size, very low to low quality evidence). Twenty-one studies reported higher knowledge scores (small to large effect size and very low quality) for the intervention, while 20 studies reported no difference in knowledge between the groups. Seven studies reported higher skill score in the intervention (large effect size and low quality), while 13 studies reported no difference in the skill scores between the groups. One study reported a higher attitude score for the intervention (very low quality), while four studies reported no difference in the attitude score between the groups. Four studies reported higher postintervention physician satisfaction with the intervention (large effect size and low quality), while six studies reported no difference in satisfaction between the groups. Eight studies reported higher postintervention practice or behavior change for the ODE group (small to moderate effect size and low quality), while five studies reported no difference in practice or behavior change between the groups. One study reported higher improvement in patient outcome, while three others reported no difference in patient outcome between the groups. None of the included studies reported any unintended/adverse effects or cost-effectiveness of the interventions.

Conclusions

Empiric evidence showed that ODE and blended learning may be equivalent to self-directed/face-to-face learning for training practicing physicians. Few other studies demonstrated that ODE and blended learning may significantly improve learning outcomes compared to self-directed/face-to-face learning. The quality of the evidence in these studies was found to be very low for knowledge. Further high-quality randomized controlled trials are required to confirm these findings.

The successful uptake and sustainability of rapid infectious disease and antimicrobial resistance point-of-care testing requires a complex 'mix-and-match' implementation package

The emergence and spread of antimicrobial resistance is one of the major global issues currently threatening the health and wealth of nations, with effective guidelines and intervention strategies urgently required. Such guidelines and interventions should ideally be targeted at individuals, communities, and nations, requiring international coordination for maximum effect. In this respect, the European Joint Programming Initiative on Antimicrobial Resistance Transnational Working Group 'Antimicrobial Resistance - Rapid Diagnostic Tests' (JPIAMR AMR-RDT) is proposing to consider a 'mix-and-match' package for the implementation of point-of-care testing (PoCT), which is described in this publication. The working group was established with the remit of identifying barriers and solutions to the development and implementation of rapid infectious disease PoCT for combatting the global spread of antimicrobial resistance. It constitutes a multi-sectoral collaboration between medical, technological, and industrial opinion leaders involved in in vitro diagnostics development, medical microbiology, and clinical infectious diseases. The mix-and-match implementation package is designed to encourage the implementation of rapid infectious disease and antimicrobial resistance PoCT in transnational medical environments for use in the fight against increasing antimicrobial resistance.

Determinants of antibiotic prescribing behaviors of primary care physicians in Hubei of China: a structural equation model based on the theory of planned behavior

Background

Over-prescription of antibiotics is prevalent all over the world, contributing to the development of antibiotic resistance. The importance of understanding how physicians prescribe antibiotics is increasingly highlighted for the purpose of promoting good practice. This study aimed to identify factors that shape the antibiotic prescribing behaviors of physicians in primary care based on the theory of planned behavior (TPB).

Methods

Data were collected from 503 prescribers within 65 primary care facilities in Hubei, tapping into four behavioral aspects leading to antibiotic prescribing based on TPB, namely, attitudes (the degree to which a prescriber is in favor of the use of antibiotics), subjective norms (perceived social pressure to which a prescriber is subject in relation to antibiotic prescriptions), perceived control of behaviors (how easy a prescriber feels in making a rational decision on antibiotic prescriptions) and intentions (the degree to which a prescriber is willing to prescribe antibiotics). A total of 440,268 prescriptions were audited to assess physician antibiotic prescribing practices. The four behavioral constructs were further linked with physician's actual use of antibiotics using structural equation modelling (SEM) based on TPB.

Results

On average, 40.54% (SD = 20.82%) of the outpatient encounters resulted in a prescription for an antibiotic given by the participants and 9.81% (SD = 10.18%) of the patients were given two or more antibiotics. The participants showing a more favorable attitude toward antibiotics had a higher intention to prescribe antibiotics (β = 0.226, p < 0.001) and a lower intention to reduce antibiotic use (β = - 0.211, p < 0.001). Those who perceived lower social pressure (β = 0.113, p = 0.030) and higher control over prescribing behaviors (β = 0.113, p = 0.037) reported a higher intention to reduce the use of antibiotics. However, such intention did not translate into prescribing practice (p > 0.05), although stronger perceived behavioral control was directly linked with lower antibiotic prescriptions (β = - 0.110, p = 0.019). Weaker perceived behavioral control was evident in the participants who showed a less favorable attitude toward antibiotics (β = 0.128, p = 0.001).

Conclusion

Antibiotic prescribing practice is not under the volitional control of prescribers in primary care in China. Their rational prescribing practice is likely to be jeopardized by perceived weak control over prescribing behaviors.

Advances in optimizing the prescription of antibiotics in outpatient settings

The inappropriate use of antibiotics can increase the likelihood of antibiotic resistance and adverse events. In the United States, nearly a third of antibiotic prescriptions in outpatient settings are unnecessary, and the selection of antibiotics and duration of treatment are also often inappropriate. Evidence shows that antibiotic prescribing is influenced by psychosocial factors, including lack of accountability, perceived patient expectations, clinician workload, and habit. A varied and growing body of evidence, including meta-analyses and randomized controlled trials, has evaluated interventions to optimize the use of antibiotics. Interventions informed by behavioral science-such as communication skills training, audit and feedback with peer comparison, public commitment posters, and accountable justification-have been associated with improved antibiotic prescribing. In addition, delayed prescribing, active monitoring, and the use of diagnostics are guideline recommended practices that improve antibiotic use for some conditions. In 2016, the Centers for Disease Control and Prevention released the Core Elements of Outpatient Antibiotic Stewardship, which provides a framework for implementing these interventions in outpatient settings. This review summarizes the varied evidence on drivers of inappropriate prescription of antibiotics in outpatient settings and potential interventions to improve their use in such settings.

Ambulatory Antibiotic Stewardship through a Human Factors Engineering Approach: A Systematic Review

INTRODUCTION

In the United States, most antibiotics are prescribed in ambulatory settings. Human factors engineering, which explores interactions between people and the place where they work, has successfully improved quality of care. However, human factors engineering models have not been explored to frame what is known about ambulatory antibiotic stewardship (AS) interventions and barriers and facilitators to their implementation.

METHODS

We conducted a systematic review and searched OVID MEDLINE, Embase, Scopus, Web of Science, and CINAHL to identify controlled interventions and qualitative studies of ambulatory AS and determine whether and how they incorporated principles from a human factors engineering model, the Systems Engineering Initiative for Patient Safety 2.0 model. This model describes how a work system (ambulatory clinic) contributes to a process (antibiotic prescribing) that leads to outcomes. The work system consists of 5 components, tools and technology, organization, person, tasks, and environment, within an external environment.

RESULTS

Of 1,288 abstracts initially identified, 42 quantitative studies and 17 qualitative studies met inclusion criteria. Effective interventions focused on tools and technology (eg, clinical decision support and point-of-care testing), the person (eg, clinician education), organization (eg, audit and feedback and academic detailing), tasks (eg, delayed antibiotic prescribing), the environment (eg, commitment posters), and the external environment (media campaigns). Studies have not focused on clinic-wide approaches to AS.

CONCLUSIONS

A human factors engineering approach suggests that investigating the role of the clinic's processes or physical layout or external pressures' role in antibiotic prescribing may be a promising way to improve ambulatory AS.

Changes in antimicrobial susceptibility of commonly clinically significant isolates before and after the interventions on surgical prophylactic antibiotics (SPAs) in Shanghai

Surveillances and interventions on antibiotics use have been suggested to improve serious drug-resistance worldwide. Since 2007, our hospital have proposed many measures for regulating surgical prophylactic antibiotics (carbapenems, third gen. cephalosporins, vancomycin, etc.) prescribing practices, like formulary restriction or replacement for surgical prophylactic antibiotics and timely feedback. To assess the impacts on drug-resistance after interventions, we enrolled infected patients in 2006 (pre-intervention period) and 2014 (post-intervention period) in a tertiary hospital in Shanghai. Proportions of targeted pathogens were analyzed: methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus spp. (VRE), imipenem-resistant Escherichia coli (IREC), imipenem-resistant Klebsiella pneumoniae (IRKP), imipenem-resistant Acinetobacter baumannii (IRAB) and imipenem-resistant Pseudomonas aeruginosa (IRPA) isolates. Rates of them were estimated and compared between Surgical Department, ICU and Internal Department during two periods. The total proportions of targeted isolates in Surgical Department (62.44%, 2006; 64.09%, 2014) were more than those in ICU (46.13%, 2006; 50.99%, 2014) and in Internal Department (44.54%, 2006; 51.20%, 2014). Only MRSA has decreased significantly (80.48%, 2006; 55.97%, 2014) (p < 0.0001). The percentages of VRE and IREC in 3 departments were all <15%, and the slightest change were also both observed in Surgical Department (VRE: 0.76%, 2006; 2.03%, 2014) (IREC: 2.69%, 2006; 2.63%, 2014). The interventions on surgical prophylactic antibiotics can be effective for improving resistance; antimicrobial stewardship must be combined with infection control practices.

Reducing early career general practitioners' antibiotic prescribing for respiratory tract infections: a pragmatic prospective non-randomised controlled trial

BACKGROUND

Inappropriate antibiotic prescription and consequent antibacterial resistance is a major threat to healthcare.

OBJECTIVES

To evaluate the efficacy of a multifaceted intervention in reducing early career general practitioners' (GPs') antibiotic prescribing for upper respiratory tract infections (URTIs) and acute bronchitis/bronchiolitis.

METHODS

A pragmatic non-randomized trial employing a non-equivalent control group design nested within an existing cohort study of GP registrars' (trainees') clinical practice. The intervention included access to online modules (covering the rationale of current clinical guidelines recommending non-prescription of antibiotics for URTI and bronchitis/bronchiolitis, and communication skills in management of acute bronchitis) followed by a face-to-face educational session. The intervention was delivered to registrars (and their supervisors) in two of Australia's seventeen regional GP training providers (RTPs). Three other RTPs were the control group. Outcomes were proportion of registrars' URTI consultations and bronchitis/bronchiolitis consultations prescribed antibiotics. Intention-to-treat analyses employed logistic regression within a Generalised Estimating Equation framework, adjusted for relevant independent variables. The predictors of interest were time; treatment group; and an interaction term for time-by-treatment group. The P value associated with an interaction term determined statistically significant differences in antibiotic prescribing.

RESULTS

Analyses include data of 217 intervention RTPs' and 311 control RTPs' registrars. There was no significant reduction in antibiotic prescribing for URTIs. For bronchitis/bronchiolitis, a significant reduction (interaction P value = 0.024) remained true for analysis adjusted for independent variables (P value = 0.040). The adjusted absolute reduction in prescribing was 15.8% (95% CI: 4.2%-27.5%).

CONCLUSIONS

A multifaceted intervention reduced antibiotic prescribing for bronchitis/bronchiolitis but not URTIs.

Focus on early-career GPs: qualitative evaluation of a multi-faceted educational intervention to improve antibiotic prescribing

BACKGROUND

We conducted an educational intervention emphasizing rational antibiotic prescribing in early-career General Practitioners (GP) in vocational training (trainees). The intervention consisted of an online introduction module, an online communication training module, face-to-face workshops, and cases to be discussed one-on-one by the trainee-supervisor dyad during regular scheduled education sessions.

OBJECTIVES

To explore the participants' experiences with the intervention.

METHODS

A qualitative study of 14 GP trainees and supervisors. Interviews followed a semi-structured interview guide, were transcribed and analysed using concurrent thematic analysis.

RESULTS

Overall, the intervention was well received. Resources were not often used in practice, but GP trainees used the information in communicating with patients. The intervention improved trainees' confidence and provided new communication strategies, e.g. explicitly asking about patients' expectations and talking patients through the examination to form an overall clinical picture. Trainees seemed eager to learn and adapt their practice, whereas GP supervisors rather commented that the intervention was reinforcing. None of the participants reported prescribing conflicts between trainee and supervisor. However, most participants identified conflicts within the GP practice or with specialists: other doctors who prescribe more antibiotics perpetuate patients' ideas that antibiotics will fix everything, which in turn causes conflict with the patient and undermines attempts to improve antibiotic prescribing.

CONCLUSION

The educational intervention was received positively. Early-career GPs thought it influenced their prescribing behaviour and improved their confidence in non-prescribing. Interventions that target teams (e.g. entire practice) could minimize conflict, ensure consistency of messages and support overall antibiotic stewardship in primary care.

An E-Learning Module to Improve Nongenetic Health Professionals' Assessment of Colorectal Cancer Genetic Risk: Feasibility Study

BACKGROUND

Nongenetic health providers may lack the relevant knowledge, experience, and communication skills to adequately detect familial colorectal cancer (CRC), despite a positive attitude toward the assessment of history of cancer in a family. Specific training may enable them to more optimally refer patients to genetic counseling.

OBJECTIVE

The aim of this study was to develop an e-learning module for gastroenterologists and surgeons (in training) aimed at improving attitudes, knowledge, and comprehension of communication skills, and to assess the feasibility of the e-learning module for continued medical education of these specialists.

METHODS

A focus group helped to inform the development of a training framework. The e-learning module was then developed, followed by a feasibility test among a group of surgeons-in-training (3rd- and 4th-year residents) and then among gastroenterologists, using pre- and posttest questionnaires.

RESULTS

A total of 124 surgeons-in-training and 14 gastroenterologists participated. The e-learning was positively received (7.5 on a scale of 1 to 10). Between pre- and posttest, attitude increased significantly on 6 out of the 10 items. Mean test score showed that knowledge and comprehension of communication skills improved significantly from 49% to 72% correct at pretest to 67% to 87% correct at posttest.

CONCLUSIONS

This study shows the feasibility of a problem-based e-learning module to help surgeons-in-training and gastroenterologists in recognizing a hereditary predisposition in patients with CRC. The e-learning led to improvements in attitude toward the assessment of cancer family history, knowledge on criteria for referral to genetic counseling for CRC, and comprehension of communication skills.

Internet and social media use for antibiotic-related information seeking: Findings from a survey among adult population in Italy

BACKGROUND

The Internet represents an increasingly common source of health-related information. Internet and Social Media can be used to promote a prudent use of antibiotics.

OBJECTIVE

To establish the extent of Internet and Social Media use to search for antibiotic related information and the potential implications in health care among adult population in Italy.

METHODS

This cross-sectional study was conducted from March to May 2017, among a sample of parents of public school students. A 2-stage cluster sample design was planned. An informed consent form and a questionnaire were given to selected students to deliver to their parents. The questionnaire included questions on knowledge, attitudes, and behavior toward antibiotic use, and questions about Internet use to gather information about antibiotics.

RESULTS

A total of 913 parents completed the questionnaire, with a 67.4% response rate; 22.1% did not know when it was appropriate to use antibiotics. 32.3% of parents reported self-medication with antibiotics. 73.4% of respondents used the Internet to search for information about antibiotic use. Among social networks users, 46.5% reported the use of these media to get information about antibiotics and 45% of instant messaging app users share information about antibiotics. The results of the multiple logistic regression analysis showed that Internet use to search for antibiotic-related information was higher among females, younger subjects, with a higher level of education, in those who reported self-medication with antibiotics and in those who needed additional information on side effects of antibiotics from the GP compared with those who did not need any additional information. Internet use was significantly less likely in participants with cardiovascular diseases and cancer compared with those without chronic conditions, and in those who reported to strongly agree/agree, or were uncertain about antibiotic use without a GP prescription, compared with those who reported to be disagree/strongly disagree.

CONCLUSIONS

Internet and social media are widely used for antibiotic-related information seeking in the Italian population. Health organizations must consider social media within their communication strategy to promote the appropriate Web use for antibiotic-related information seeking in the general population, although more evidence is needed regarding the optimal mix of communication interventions.

Qualitative interview study of antibiotics and self-management strategies for respiratory infections in primary care

OBJECTIVE

To explore perceptions of illness, the decisions to consult and the acceptability of delayed antibiotic prescriptions and self-help treatments for respiratory tract infections (RTIs).

DESIGN

Qualitative semistructured interview study.

SETTING

UK primary care.

PARTICIPANTS

20 adult patients who had been participating in the 'PIPS' (Pragmatic Ibuprofen Paracetamol and Steam) trial in the South of England.

METHOD

Semistructured telephone interviews were conducted with participants to explore their experiences and views on various treatments for RTI.

RESULTS

Participants had concerns about symptoms that were not clinically serious and were mostly unaware of the natural history of RTIs, but were aware of the limitations of antibiotics and did not expect them with every consultation. Most viewed delayed prescriptions positively and had no strong preference over which technique is used to deliver the delayed antibiotic, but some patients received mixed messages, such as being told their infection was viral then being given an antibiotic, or were sceptical about the rationale. Participants disliked self-help treatments that involved taking medication and were particularly concerned about painkillers in combination. Steam inhalation was viewed as only moderately helpful for mild symptoms.

CONCLUSION

Delayed prescribing is acceptable no matter how the delay is operationalised, but explanation of the rationale is needed and care taken to minimise mixed messages about the severity of illnesses and causation by viruses or bacteria. Better access is needed to good natural history information, and the signs and symptoms requiring or not requiring general practitioner advice. Significant concerns about paracetamol, ibuprofen and steam inhalation are likely to need careful exploration in the consultation.

A novel host-protein assay outperforms routine parameters for distinguishing between bacterial and viral lower respiratory tract infections

Bacterial and viral lower respiratory tract infections (LRTIs) are often clinically indistinguishable, leading to antibiotic overuse. We compared the diagnostic accuracy of a new assay that combines 3 host-biomarkers (TRAIL, IP-10, CRP) with parameters in routine use to distinguish bacterial from viral LRTIs. Study cohort included 184 potentially eligible pediatric and adult patients. Reference standard diagnosis was based on adjudication by an expert panel following comprehensive clinical and laboratory investigation (including respiratory PCRs). Experts were blinded to assay results and assay performers were blinded to reference standard outcomes. Evaluated cohort included 88 bacterial and 36 viral patients (23 did not fulfill inclusion criteria; 37 had indeterminate reference standard outcome). Assay distinguished bacterial from viral LRTI patients with sensitivity of 0.93±0.06 and specificity of 0.91±0.09, outperforming routine parameters, including WBC, CRP and chest x-ray signs. These findings support the assay's potential to help clinicians avoid missing bacterial LRTIs or overusing antibiotics.

Maltese Antibiotic Stewardship Programme in the Community (MASPIC): protocol of a prospective quasiexperimental social marketing intervention

INTRODUCTION

Antibiotic misuse is a key driver of antibiotic resistance. In 2015/2016, Maltese respondents reported the highest proportions of antibiotic consumption in Europe. Since antibiotics are prescription-only medicines in Malta, research on effective strategies targeting general practitioners' (GPs) knowledge and behaviour is needed. Multifaceted behaviour change (BC) interventions are likely to be effective. Social marketing (SM) can provide the tools to promote sustained BC; however, its utilisation in Europe is limited. This paper aims to describe the design and methods of a multifaceted SM intervention aimed at changing Maltese GPs' antibiotic prescribing behaviour for patients with acute respiratory tract infections (aRTIs).

METHODS AND ANALYSIS

This 4-year quasiexperimental intervention study will be carried out in Malta and includes three phases: preintervention, intervention and postintervention. The preintervention phase intends to gain insight into the practices and attitudes of GPs, pharmacists and parents through interviews, focus group discussions and antibiotic prescribing surveillance. A 6-month intervention targeting GPs will be implemented following assessment of their prescribing intention and readiness for BC. The intervention will likely comprise: prescribing guidelines, patient educational materials, delayed antibiotic prescriptions and GP education. Outcomes will be evaluated in the postintervention phase through questionnaires based on the theory of planned behaviour and stages-of-change theory, as well as postintervention surveillance. The primary outcome will be the antibiotic prescribing rate for all patients with aRTIs. Secondary outcomes will include the proportion of diagnosis-specific antibiotic prescription and symptomatic relief medication prescribed, and the change in GPs stage-of-change and their intention to prescribe antibiotics.

ETHICS AND DISSEMINATION

The project received ethical approval from the University of Malta's Research Ethics Committee. Should this intervention successfully decrease antibiotic prescribing, it may be scaled up locally and transferred to similar settings.

Clinician-targeted interventions to influence antibiotic prescribing behaviour for acute respiratory infections in primary care: an overview of systematic reviews

BACKGROUND

Antibiotic resistance is a worldwide health threat. Interventions that reduce antibiotic prescribing by clinicians are expected to reduce antibiotic resistance. Disparate interventions to change antibiotic prescribing behaviour for acute respiratory infections (ARIs) have been trialled and meta-analysed, but not yet synthesised in an overview. This overview synthesises evidence from systematic reviews, rather than individual trials.

OBJECTIVES

To systematically review the existing evidence from systematic reviews on the effects of interventions aimed at influencing clinician antibiotic prescribing behaviour for ARIs in primary care.

METHODS

We searched the Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects (DARE), MEDLINE, Embase, CINAHL, PsycINFO, and Science Citation Index to June 2016. We also searched the reference lists of all included reviews. We ran a pre-publication search in May 2017 and placed additional studies in 'awaiting classification'.We included both Cochrane and non-Cochrane reviews of randomised controlled trials evaluating the effect of any clinician-focussed intervention on antibiotic prescribing behaviour in primary care. Two overview authors independently extracted data and assessed the methodological quality of included reviews using the ROBIS tool, with disagreements reached by consensus or by discussion with a third overview author. We used the GRADE system to assess the quality of evidence in included reviews. The results are presented as a narrative overview.

MAIN RESULTS

We included eight reviews in this overview: five Cochrane Reviews (33 included trials) and three non-Cochrane reviews (11 included trials). Three reviews (all Cochrane Reviews) scored low risk across all the ROBIS domains in Phase 2 and low risk of bias overall. The remaining five reviews scored high risk on Domain 4 of Phase 2 because the 'Risk of bias' assessment had not been specifically considered and discussed in the review Results and Conclusions. The trials included in the reviews varied in both size and risk of bias. Interventions were compared to usual care.Moderate-quality evidence indicated that C-reactive protein (CRP) point-of-care testing (risk ratio (RR) 0.78, 95% confidence interval (CI) 0.66 to 0.92, 3284 participants, 6 trials), shared decision making (odds ratio (OR) 0.44, 95% CI 0.26 to 0.75, 3274 participants, 3 trials; RR 0.64, 95% CI 0.49 to 0.84, 4623 participants, 2 trials; risk difference -18.44, 95% CI -27.24 to -9.65, 481,807 participants, 4 trials), and procalcitonin-guided management (adjusted OR 0.10, 95% CI 0.07 to 0.14, 1008 participants, 2 trials) probably reduce antibiotic prescribing in general practice. We found moderate-quality evidence that procalcitonin-guided management probably reduces antibiotic prescribing in emergency departments (adjusted OR 0.34, 95% CI 0.28 to 0.43, 2605 participants, 7 trials). The overall effect of these interventions was small (few achieving greater than 50% reduction in antibiotic prescribing, most about a quarter or less), but likely to be clinically important.Compared to usual care, shared decision making probably makes little or no difference to reconsultation for the same illness (RR 0.87, 95% CI 0.74 to 1.03, 1860 participants, 4 trials, moderate-quality evidence), and may make little or no difference to patient satisfaction (RR 0.86, 95% CI 0.57 to 1.30, 1110 participants, 2 trials, low-quality evidence). Similarly, CRP testing probably has little or no effect on patient satisfaction (RR 0.79, 95% CI 0.57 to 1.08, 689 participants, 2 trials, moderate-quality evidence) or reconsultation (RR 1.08, 95% CI 0.93 to 1.27, 5132 participants, 4 trials, moderate-quality evidence). Procalcitonin-guided management probably results in little or no difference in treatment failure in general practice compared to normal care (adjusted OR 0.95, 95% CI 0.73 to 1.24, 1008 participants, 2 trials, moderate-quality evidence), however it probably reduces treatment failure in the emergency department compared to usual care (adjusted OR 0.76, 95% CI 0.61 to 0.95, 2605 participants, 7 trials, moderate-quality evidence).The quality of evidence for interventions focused on clinician educational materials and decision support in reducing antibiotic prescribing in general practice was either low or very low (no pooled result reported) and trial results were highly heterogeneous, therefore we were unable draw conclusions about the effects of these interventions. The use of rapid viral diagnostics in emergency departments may have little or no effect on antibiotic prescribing (RR 0.86, 95% CI 0.61 to 1.22, 891 participants, 3 trials, low-quality evidence) and may result in little to no difference in reconsultation (RR 0.86, 95% CI 0.59 to 1.25, 200 participants, 1 trial, low-quality evidence).None of the trials in the included reviews reported on management costs for the treatment of an ARI or any associated complications.

AUTHORS' CONCLUSIONS

We found evidence that CRP testing, shared decision making, and procalcitonin-guided management reduce antibiotic prescribing for patients with ARIs in primary care. These interventions may therefore reduce overall antibiotic consumption and consequently antibiotic resistance. There do not appear to be negative effects of these interventions on the outcomes of patient satisfaction and reconsultation, although there was limited measurement of these outcomes in the trials. This should be rectified in future trials.We could gather no information about the costs of management, and this along with the paucity of measurements meant that it was difficult to weigh the benefits and costs of implementing these interventions in practice.Most of this research was undertaken in high-income countries, and it may not generalise to other settings. The quality of evidence for the interventions of educational materials and tools for patients and clinicians was either low or very low, which prevented us from drawing any conclusions. High-quality trials are needed to further investigate these interventions.

Behavioral Approach to Appropriate Antimicrobial Prescribing in Hospitals: The Dutch Unique Method for Antimicrobial Stewardship (DUMAS) Participatory Intervention Study

Importance

Inappropriate antimicrobial prescribing leads to antimicrobial resistance and suboptimal clinical outcomes. Changing antimicrobial prescribing is a complex behavioral process that is not often taken into account in antimicrobial stewardship programs.

Objective

To examine whether an antimicrobial stewardship approach grounded in behavioral theory and focusing on preserving prescriber autonomy and participation is effective in improving appropriateness of antimicrobial prescribing in hospitals.

Design, Setting, and Participants

The Dutch Unique Method for Antimicrobial Stewardship (DUMAS) study was a prospective, stepped-wedge, participatory intervention study performed from October 1, 2011, through December 31, 2015. Outcomes were measured during a baseline period of 16 months and an intervention period of 12 months. The study was performed at 7 clinical departments (2 medical, 3 surgical, and 2 pediatric) in a tertiary care medical center and a general teaching hospital in the Netherlands. Physicians prescribing systemic antimicrobial drugs for any indication for patients admitted to the participating departments during the study period were included in the study.

Interventions

We offered prescribers a free choice of how to improve their antimicrobial prescribing. Prescribers were stimulated to choose interventions with higher potential for success based on a root cause analysis of inappropriate prescribing.

Main Outcomes and Measures

Appropriateness of antimicrobial prescriptions was determined using a validated approach based on guideline adherence and motivated guideline deviation and measured with repeated point prevalence surveys (6 per year). Appropriateness judgment was masked for the study period. Antimicrobial consumption was extracted from pharmacy records and measured as days of therapy per admission. We used linear and logistic mixed-model regression analysis to model outcomes over time.

Results

A total of 1121 patient cases with 700 antimicrobial prescriptions were assessed during the baseline period and 882 patient cases with 531 antimicrobial prescriptions during the intervention period. The mean antimicrobial appropriateness increased from 64.1% at intervention start to 77.4% at 12-month follow-up (+13.3%; relative risk, 1.17; 95% CI, 1.04-1.27), without a change in slope. No decrease in antimicrobial consumption was found.

Conclusions and Relevance

Use of a behavioral approach preserving prescriber autonomy resulted in an increase in antimicrobial appropriateness sustained for at least 12 months. The approach is inexpensive and could be easily transferable to various health care environments.

How French general practitioners manage and prevent recurrent respiratory tract infections in children: the SOURIRRE survey

BACKGROUND

Recurrent respiratory tract infections (RRTIs) are the most common reason for children's visits to primary care physicians in France; however, little is known about general practitioners' (GPs) opinions and expectations concerning the management and prevention of these common and recurrent pathologies.

PURPOSE

To describe French GPs' daily practice in the management of respiratory infections and the prevention of their recurrence in children.

METHODS

A sample group of French GPs answered a structured questionnaire on risk factors, RRTI management, antibiotic use and prevention measures.

RESULTS

A total of 358 GPs participated in the survey. Rhinopharyngitis, the most frequent respiratory infection, was considered to be recurrent if six or more episodes occurred in a year. Four risk factors were acknowledged as substantial: living in communities, passive smoking, pollution and allergies. Around 63% of GPs said that RRTIs are too often treated with antibiotics. More than 85% thought that prevention of RRTIs is possible. Smoking cessation, vaccination, allergen avoidance and hygiene were identified as the main preventive measures. A large majority of GPs (84%) prescribed products for prevention and ~90% would prescribe a product stimulating immunity if the efficacy and tolerability of these agents was proven and confirmed in their daily practice.

CONCLUSIONS

French GPs are well aware of the health and socioeconomic burdens resulting from RRTIs, as well as the risk of antibiotic overuse. They have a prevention-oriented approach, implement preventive measures when possible and prescribe products for prevention.

Microbiological point of care testing before antibiotic prescribing in primary care: considerable variations between practices

Background

Point-of-care testing (POCT) in primary care may improve rational antibiotic prescribing. We examined use of POCT in Denmark, including patient- and general practitioner (GP)-related predictors.

Methods

We linked nationwide health care databases to assess POCT use (C-reactive protein (CRP), group A streptococcal (GAS) antigen swabs, bacteriological cultures, and urine test strips) per 1,000 overall GP consultations, 2004–2013. We computed odds ratios (OR) of POCT in patients prescribed antibiotics according to patient and GP age and sex, GP practice type, location, and workload.

Results

The overall use of POCT in Denmark increased by 45.8% during 2004–2013, from 147.2 per 1,000 overall consultations to 214.8. CRP tests increased by 132%, bacteriological cultures by 101.7% while GAS swabs decreased by 8.6%. POCT preceded 28% of antibiotic prescriptions in 2004 increasing to 44% in 2013. The use of POCT varied more than 5-fold among individual practices, from 54.9 to 394.7 per 1,000 consultations in 2013. POCT use varied substantially with patient age, and males were less likely to receive POCT than females (adjusted OR = 0.75, 95% CI 0.74-0.75) driven by usage of urine test strips among females (18% vs. 7%). Odds of POCT were higher among female GPs and decreased with higher GP age, with lowest usage among male GPs >60 years. GP urban/rural location and workload had little impact.

Conclusion

GPs use POCT increasingly with the highest use among young female GPs. In 2013, 44% of all antibiotic prescriptions were preceded by POCT but testing rates vary greatly across individual GPs.

Predictors of fever-related admissions to a paediatric assessment unit, ward and reattendances in a South London emergency department: the CABIN 2 study

OBJECTIVE

To explore the risk factors for ward and paediatric assessment unit (PAU) admissions from the emergency department (ED).

DESIGN

Prospective observational study.

SETTING AND PATIENTS

Febrile children attending a large tertiary care ED during the winter of 2014-2015.

MAIN OUTCOME MEASURES

Ward and PAU admissions, National Institute for Health and Care Excellence (NICE) guidelines classification, reattendance to the ED within 28 days and antibiotic use.

RESULTS

A total of 1097 children attending the children's ED with fever were analysed. Risk factors for PAU admission were tachycardia (RR=1.1, 95% CI (1 to 1.1)), ill-appearance (RR=2.2, 95% CI (1.2 to 4.2)), abnormal chest findings (RR=2.1, 95% CI (1.2 to 4.3)), categorised as NICE amber (RR 1.7 95% CI (1.2 to 2.5)). There was a 30% discordance between NICE categorisation at triage and statistical internal validation. Predictors of ward admission were a systemic (RR=6.9, 95% CI (2.4 to 19.8)) or gastrointestinal illness (RR=3.8, 95% (1.4 to 10.4)) and categorised as NICE Red (RR=5.9, 95% CI (2.2 to 15.3)). Only 51 children had probable bacterial pneumonia (4.6%), 52 children had a proven urinary tract infection (4.2%), with just 2 (0.2%) positive blood cultures out of 485 (44%) children who received an antibiotic. 15% of all children reattended by 28 days and were more likely to have been categorised as Amber and had investigations on initial visit.

CONCLUSIONS

Risk factors for PAU and ward admissions are different in this setting with high reattendance rates and very low proportion of confirmed/probable serious bacterial infections. Future studies need to focus on reducing avoidable admissions and antibiotic treatment.

Combined assessment of clinical and patient factors on doctors' decisions to prescribe antibiotics

BACKGROUND

Antibiotic overprescription is a worldwide problem. Decisions regarding antibiotic prescription for respiratory tract infections (RTIs) are influenced by medical and non-medical factors.

METHODS

In family medicine practices in Białystok, Poland, family medicine residents directly observed consultations with patients with RTI symptoms. The observing residents completed a questionnaire including patient data, clinical symptoms, diagnosis, any prescribed antibiotic, and assessment of ten patient pressure factors.

RESULTS

Of 1546 consultations of patients with RTIs, 54.26 % resulted in antibiotic prescription. Antibiotic prescription was strongly associated with rales (OR 26.90, 95 % CI 9.00-80.40), tonsillar exudates (OR 13.03, 95 % CI 7.10-23.80), and wheezing (OR 14.72, 95 % CI 7.70-28.10). The likelihood of antibiotic prescription was increased by a >7-day disease duration (OR 3.94, 95 % CI 2.80-5.50), purulent nasal discharge (OR 3.87, 95 % CI 2.40-6.10), starting self-medication with antibiotics (OR 4.11, 95 % CI 2.30-7.30), and direct request for antibiotics (OR 1.87, 95 % CI 1.30-2.80). Direct request not to prescribe antibiotics decreased the likelihood of receiving antibiotics (OR 0.34, 95 % CI 0.27-0.55).

CONCLUSION

While clinical signs and symptoms principally impact prescribing decisions, patient factors also contribute. The most influential patient pressure factors were starting self-medication with antibiotics, and directly requesting antibiotic prescription or no antibiotic prescription. Interventions aiming to improve clinical sign and symptom interpretation and to help doctors resist direct patient pressure could be beneficial for reducing unnecessary antibiotic prescribing.

Discrepancies between qualitative and quantitative evaluation of randomised controlled trial results: achieving clarity through mixed methods triangulation

BACKGROUND

Mixed methods are commonly used in health services research; however, data are not often integrated to explore complementarity of findings. A triangulation protocol is one approach to integrating such data. A retrospective triangulation protocol was carried out on mixed methods data collected as part of a process evaluation of a trial. The multi-country randomised controlled trial found that a web-based training in communication skills (including use of a patient booklet) and the use of a C-reactive protein (CRP) point-of-care test decreased antibiotic prescribing by general practitioners (GPs) for acute cough. The process evaluation investigated GPs' and patients' experiences of taking part in the trial.

METHODS

Three analysts independently compared findings across four data sets: qualitative data collected view semi-structured interviews with (1) 62 patients and (2) 66 GPs and quantitative data collected via questionnaires with (3) 2886 patients and (4) 346 GPs. Pairwise comparisons were made between data sets and were categorised as agreement, partial agreement, dissonance or silence.

RESULTS

Three instances of dissonance occurred in 39 independent findings. GPs and patients reported different views on the use of a CRP test. GPs felt that the test was useful in convincing patients to accept a no-antibiotic decision, but patient data suggested that this was unnecessary if a full explanation was given. Whilst qualitative data indicated all patients were generally satisfied with their consultation, quantitative data indicated highest levels of satisfaction for those receiving a detailed explanation from their GP with a booklet giving advice on self-care. Both qualitative and quantitative data sets indicated higher patient enablement for those in the communication groups who had received a booklet.

CONCLUSIONS

Use of CRP tests does not appear to engage patients or influence illness perceptions and its effect is more centred on changing clinician behaviour. Communication skills and the patient booklet were relevant and useful for all patients and associated with increased patient satisfaction. A triangulation protocol to integrate qualitative and quantitative data can reveal findings that need further interpretation and also highlight areas of dissonance that lead to a deeper insight than separate analyses.

Provider Decisions to Treat Respiratory Illnesses with Antibiotics: Insights from a Randomized Controlled Trial

RATIONALE

Lower respiratory tract illness (LRTI) frequently causes adult hospitalization and antibiotic overuse. Procalcitonin (PCT) treatment algorithms have been used successfully in Europe to safely reduce antibiotic use for LRTI but have not been adopted in the United States. We recently performed a feasibility study for a randomized clinical trial (RCT) of PCT and viral testing to guide therapy for non-pneumonic LRTI.

OBJECTIVE

The primary objective of the current study was to understand factors influencing PCT algorithm adherence during the RCT and evaluate factors influencing provider antibiotic prescribing practices for LRTI.

STUDY DESIGN

From October 2013-April 2014, 300 patients hospitalized at a community teaching hospital with non-pneumonic LRTI were randomized to standard or PCT-guided care with viral PCR testing. Algorithm adherence data was collected and multivariate stepwise logistic regression of clinical variables used to model algorithm compliance. 134 providers were surveyed anonymously before and after the trial to assess knowledge of biomarkers and viral testing and antibiotic prescribing practices.

RESULTS

Diagnosis of pneumonia on admission was the only variable significantly associated with non-adherence [7% (adherence) vs. 26% (nonadherence), p = 0.01]. Surveys confirmed possible infiltrate on chest radiograph as important for provider decisions, as were severity of illness, positive sputum culture, abnormal CBC and fever. However, age, patient expectations and medical-legal concerns were also at least somewhat important to prescribing practices. Physician agreement with the importance of viral and PCT testing increased from 42% to 64% (p = 0.007) and 49% to 74% (p = 0.001), respectively, after the study.

CONCLUSIONS

Optimal algorithm adherence will be important for definitive PCT intervention trials in the US to determine if PCT guided algorithms result in better outcomes than reliance on traditional clinical variables. Factors influencing treatment decisions such as patient age, presence of fever, patient expectations and medical legal concerns may be amenable to education to improve PCT algorithm compliance for LRTI.

How can we improve antibiotic prescribing in primary care?

Antibiotic stewardship is a necessity given the worldwide antimicrobial resistance crisis. Outpatient antibiotic use represents around 90% of total antibiotic use, with more than half of these prescriptions being either unnecessary or inappropriate. Efforts to improve antibiotic prescribing need to incorporate two complementary strategies: changing healthcare professionals' behaviour, and modifying the healthcare system. In this review, we present a broad perspective on antibiotic stewardship in primary care in high and high-middle income country settings, focussing on studies published in the last five years. We present the limitations of available literature, discuss perspectives, and provide suggestions for where future work should be concentrated.

Reducing general practice trainees' antibiotic prescribing for respiratory tract infections: an evaluation of a combined face-to-face workshop and online educational intervention

Over-prescription of antibiotics for non-pneumonia respiratory tract infections (RTIs) is a major concern in general practice. Australian general practice registrars (trainees) have inappropriately high rates of prescription of antibiotics for RTIs. The 'apprenticeship' educational model and the trainee-trainer relationship are drivers of this inappropriate prescribing. We aimed to reduce registrars' non-pneumonia RTI antibiotic prescribing via an educational intervention (a 90-min face-to-face workshop supported by online modules), complemented by delivery of the same intervention, separately, to their trainers. We conducted a pre- and post-intervention comparison of the registrars' intention to prescribe antibiotics for common RTIs using McNemar's test. We similarly tested changes in supervisors' intended prescribing. Prescribing intentions were elicited by responses to six written clinical vignettes (upper respiratory tract infection, otitis media, sore throat and three acute bronchitis vignettes). We found that, for registrars, there were statistically significant reductions in antibiotic prescribing for the sore throat (24.0% absolute reduction), otitis media (17.5% absolute reduction) and two of the three acute bronchitis (12.0% and 18.0% absolute reduction) vignettes. There were significant reductions in supervisors' antibiotic prescribing intentions for the same four vignettes. We conclude that our intervention produced a significant change in registrars' intention to prescribe antibiotics for non-pneumonia RTIs.

Time series analysis of the impact of an intervention in Tayside, Scotland to reduce primary care broad-spectrum antimicrobial use

OBJECTIVES

Concern about Clostridium difficile infection (CDI) and resistance has driven interventions internationally to reduce broad-spectrum antimicrobial use. An intervention combining guidelines, education and feedback was implemented in Tayside, Scotland in 2009 aiming to reduce primary care prescribing of co-amoxiclav, cephalosporins, fluoroquinolones and clindamycin ('4C antimicrobials'). Our aim was to assess the impact of this real-world intervention on antimicrobial prescribing rates.

METHODS

We used interrupted time series with segmented regression analysis to examine associations between the intervention and changes in antimicrobial prescribing (quarterly rates of patients exposed to 4C antimicrobials, non-4C antimicrobials and any antimicrobial in 2005-12).

RESULTS

The intervention was associated with a highly significant and sustained decrease in 4C antimicrobial prescribing, by 33.5% (95% CI -26.1 to -40.9), 42.2% (95% CI -34.2 to -50.2) and 55.5% (95% CI -45.9 to -65.1) at 6, 12 and 24 months after intervention, respectively. The effect was seen across all age groups, with the largest reductions in people aged 65 years and over (58.4% reduction at 24 months, 95% CI -46.7 to -70.1) and care home residents (65.6% reduction at 24 months, 95% CI -51.8 to -79.4). There were balancing increases in doxycycline, nitrofurantoin and trimethoprim prescribing as well as a reduction in macrolide prescribing. Total antimicrobial exposure did not change.

CONCLUSIONS

A real-world intervention to reduce primary care prescribing of antimicrobials associated with CDI led to large, sustained reductions in the targeted prescribing, largely due to substitution with guideline-recommended antimicrobials rather than by avoiding antimicrobial use altogether. Further research is needed to examine the impact on antimicrobial resistance.
