Pragmatic randomised trial assessing the impact of peer comparison and therapeutic recommendations, including repetition, on antibiotic prescribing patterns of family physicians across British Columbia for uncomplicated lower urinary tract infections

OBJECTIVE

To evaluate the impact of a personalised audit and feedback prescribing report (AF) and brief educational summary (ES) on empiric treatment of uncomplicated lower urinary tract infections (UTIs) by family physicians (FPs).

DESIGN

Cluster randomised control trial.

SETTING

The intervention was conducted in British Columbia, Canada between 23 September 2021 and 28 March 2022.

PARTICIPANTS

We randomised 5073 FPs into a standard AF and ES intervention arm (n=1691), an ES-only arm (n=1691) and a control arm (n=1691).

INTERVENTIONS

The AF contained personalised and peer-comparison data on first-line antibiotic prescriptions for women with uncomplicated lower UTI and key therapeutic recommendations. The ES contained detailed, evidence-based UTI management recommendations, incorporated regional antibiotic resistance data and recommended nitrofurantoin as a first-line treatment.

MAIN OUTCOME MEASURES

Nitrofurantoin as first-line pharmacological treatment for uncomplicated lower UTI, analysed using an intention-to-treat approach.

RESULTS

We identified 21 307 cases of uncomplicated lower UTI among the three trial arms during the study period. The impact of receiving both the AF and ES increased the relative probability of prescribing nitrofurantoin as first-line treatment for uncomplicated lower UTI by 28% (OR 1.28; 95% CI 1.07 to 1.52), relative to the delay arm. This translates to additional prescribing of nitrofurantoin as first-line treatment, instead of alternates, in an additional 8.7 cases of uncomplicated UTI per 100 FPs during the 6-month study period.

CONCLUSION

AF prescribing data with educational materials can improve primary care prescribing of antibiotics for uncomplicated lower UTI.

Effects of social norm feedback on adherence to clinical practice guidelines among healthcare workers and its characteristics in behavior change techniques: A systematic review and meta-analysis

BACKGROUND

Poor adherence to clinical practice guidelines among healthcare workers could have negative impacts on the effectiveness of care, patient health outcomes, and healthcare costs. Social norm feedback can be an essential means of achieving the intended intervention goals by providing information to the intervention target regarding the values, attitudes, or behaviors of the reference group or individual. However, there is a lack of consensus on the effectiveness of social norm feedback in improving adherence to clinical practice guidelines among healthcare workers. Therefore, this systematic review aimed to assess the effects of social norm feedback on adherence to clinical practice guidelines among healthcare workers and its characteristics in behavior change techniques.

METHODS

Searches of PubMed, Web of Science, Cochrane Central Register of Controlled Trials (via CENTRAL), EMBASE (via OVID), MEDLINE (via OVID), and Scopus were preformed to identify peer-reviewed studies published until February 29, 2024. Randomized controlled trials reporting social norm feedback interventions (social comparison, information about others' approval, credible source, social reward, and social incentive) to support compliance with clinical practice guidelines were included. The risk of bias of individual studies was assessed using the Cochrane Risk of Bias 2.0 tool and the certainty of evidence was rated using the GRADE method. Pooled data were analyzed in Stata 17.0 using a random effects model meta-analysis.

RESULTS

A total of 31 articles (30 studies) were identified. Fifteen behavior change techniques were tested in the included studies. The three most commonly used behavior change techniques in clinical practice guidelines were social comparison, feedback on the outcome of behavior, and social support. A meta-analysis showed that social norm feedback appeared to be an effective strategy to improve adherence to clinical practice guidelines among healthcare workers, with a rate difference (RD) of 0.04 (95 % confidence interval [CI] 0.02-0.06). Credible source (RD 0.12, 95 % CI 0.06-0.19) and multiple social norms behavioral change techniques (RD 0.05, 95 % CI 0.04-0.06) seemed effective when combined with other behavioral change techniques, compared to the control condition. The certainty of evidence across the outcomes ranged from very low to high based on the GRADE approach.

CONCLUSION

Social norm feedback appears to be an effective method for improving adherence to clinical practice guidelines among healthcare workers. This review provides a broad understanding of how social norm feedback can be applied to improve adherence of healthcare workers to clinical practice guidelines, ultimately improving patient health and quality of care.

Audit and Feedback Interventions for Antibiotic Prescribing in Primary Care: A Systematic Review and Meta-analysis

BACKGROUND

This systematic review evaluates the effect of audit and feedback (A&F) interventions targeting antibiotic prescribing in primary care and examines factors that may explain the variation in effectiveness.

METHODS

Randomized controlled trials (RCTs) involving A&F interventions targeting antibiotic prescribing in primary care were included in the systematic review. Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, and ClinicalTrials.gov were searched up to May 2024. Trial, participant, and intervention characteristics were extracted independently by 2 researchers. Random effects meta-analyses of trials that compared interventions with and without A&F were conducted for 4 outcomes: (1) total antibiotic prescribing volume; (2) unnecessary antibiotic initiation; (3) excessive prescription duration, and (4) broad-spectrum antibiotic selection. A stratified analysis was also performed based on study characteristics and A&F intervention design features for total antibiotic volume.

RESULTS

A total of 56 RCTs fit the eligibility criteria and were included in the meta-analysis. A&F was associated with an 11% relative reduction in antibiotic prescribing volume (N = 21 studies, rate ratio [RR] = 0.89; 95% confidence interval [CI]: .84, .95; I2 = 97); 23% relative reduction in unnecessary antibiotic initiation (N = 16 studies, RR = 0.77; 95% CI: .68, .87; I2 = 72); 13% relative reduction in prolonged duration of antibiotic course (N = 4 studies, RR = 0.87 95% CI: .81, .94; I2 = 86); and 17% relative reduction in broad-spectrum antibiotic selection (N = 17 studies, RR = 0.83 95% CI: .75, .93; I2 = 96).

CONCLUSIONS

A&F interventions reduce antibiotic prescribing in primary care. However, heterogeneity was substantial, outcome definitions were not standardized across the trials, and intervention fidelity was not consistently assessed. Clinical Trials Registration. Prospero (CRD42022298297).

Changing the antibiotic prescribing of Australian general practice registrars' for acute respiratory tract infections: a non-randomized controlled trial

BACKGROUND

Inappropriate antibiotic prescription for self-limiting respiratory tract infections (RTIs) by general practitioner (GP) registrars (trainees) is less common than by established GPs but still exceeds evidence-based benchmarks. A 2014 face-to-face educational intervention for registrars and supervisors reduced registrars' acute bronchitis antibiotic prescription by 16% (absolute reduction). We aimed to establish the efficacy of an updated registrar/supervisor RTI-management intervention (delivered at distance) on antibiotic prescribing.

METHODS

A non-randomized trial using a non-equivalent control-group nested within the ReCEnT cohort study. The intervention included online educational modules, registrar and supervisor webinars, and materials for registrar-supervisor in-practice educational sessions, and focussed on acute bronchitis as an exemplar RTI. The theoretical underpinning was the 'capability, opportunity, and motivation' (COM-B) framework. The intervention was delivered to registrars and supervisors of one large educational/training organization annually from mid-2021, with pre-intervention period from 2017, and with postintervention period ending 2023. Two other educational/training organizations served as controls. The primary outcome was antibiotics prescribed for acute bronchitis. Analyses used multivariable logistic regression with predictors of interest: time (before/after intervention), treatment group, and an interaction term for time-by-treatment group, adjusted for potential confounders. The interaction term P-value was used to infer statistical significance of the intervention effect.

RESULTS

Of 4612 acute bronchitis presentations, 70% were prescribed antibiotics. There was a 6.9% absolute reduction (adjusted) of prescribing in the intervention-group compared with the control-group. This was not statistically significant (Pinteraction = .22).

CONCLUSIONS

Failure to find a significant effect on prescribing suggests difficulties with scalability of this (and similar educational) innovations.

Exploring the content and delivery of feedback facilitation co-interventions: a systematic review

BACKGROUND

Policymakers and researchers recommend supporting the capabilities of feedback recipients to increase the quality of care. There are different ways to support capabilities. We aimed to describe the content and delivery of feedback facilitation interventions delivered alongside audit and feedback within randomised controlled trials.

METHODS

We included papers describing feedback facilitation identified by the latest Cochrane review of audit and feedback. The piloted extraction proforma was based upon a framework to describe intervention content, with additional prompts relating to the identification of influences, selection of improvement actions and consideration of priorities and implications. We describe the content and delivery graphically, statistically and narratively.

RESULTS

We reviewed 146 papers describing 104 feedback facilitation interventions. Across included studies, feedback facilitation contained 26 different implementation strategies. There was a median of three implementation strategies per intervention and evidence that the number of strategies per intervention is increasing. Theory was used in 35 trials, although the precise role of theory was poorly described. Ten studies provided a logic model and six of these described their mechanisms of action. Both the exploration of influences and the selection of improvement actions were described in 46 of the feedback facilitation interventions; we describe who undertook this tailoring work. Exploring dose, there was large variation in duration (15-1800 min), frequency (1 to 42 times) and number of recipients per site (1 to 135). There were important gaps in reporting, but some evidence that reporting is improving over time.

CONCLUSIONS

Heterogeneity in the design of feedback facilitation needs to be considered when assessing the intervention's effectiveness. We describe explicit feedback facilitation choices for future intervention developers based upon choices made to date. We found the Expert Recommendations for Implementing Change to be valuable when describing intervention components, with the potential for some minor clarifications in terms and for greater specificity by intervention providers. Reporting demonstrated extensive gaps which hinder both replication and learning. Feedback facilitation providers are recommended to close reporting gaps that hinder replication. Future work should seek to address the 'opportunity' for improvement activity, defined as factors that lie outside the individual that make care or improvement behaviour possible.

Diagnosis-linked antibiotic prescribing quality indicators: demonstrating feasibility using practice-based routine primary care data, reliability, validity and their potential in antimicrobial stewardship

BACKGROUND

Quality indicators (QIs) can be used to obtain valuable insights into prescribing quality. Five quantitative and nine diagnosis-linked QIs, aiming to provide general practitioners (GP) with feedback on their antibiotic prescribing quantity and quality, were previously developed and evaluated in a controlled study.

OBJECTIVE

To confirm, in a larger non-controlled study, the feasibility of using routinely collected and extracted electronic patient records to calculate the diagnosis-linked QI outcomes for antibiotic prescribing, and their reliability and validity.

METHODS

Retrospective study involving 299 Dutch general practices using routine care data (2018-2020). QIs describe total antibiotic and subgroup prescribing, prescribing percentages and first-choice prescribing for several clinical diagnoses. Practice variation in QI outcomes, inter-QI outcome correlations and sensitivity of QI outcomes to pandemic-induced change were determined.

RESULTS

QI outcomes were successfully obtained for 278/299 practices. With respect to reliability, outcomes for 2018 and 2019 were comparable, between-practice variation in outcomes was similar to the controlled pilot, and inter-QI outcome correlations were as expected, for example: high prescribing of second choice antibiotics with low first-choice prescribing for clinical diagnoses. Validity was confirmed by their sensitivity to pandemic-induced change: total antibiotic prescribing decreased from 282 prescriptions/1000 registered patients in 2018 to 216 in 2020, with a decrease in prescribing percentages for upper and lower respiratory infections, from 26% to 18.5%, and from 28% to 16%.

CONCLUSIONS

This study confirmed the fit-for-purpose (feasibility, reliability and validity) of the antibiotic prescribing QIs (including clinical diagnosis-linked ones) using routinely registered primary health care data as a source. This feedback can therefore be used in antibiotic stewardship programmes to improve GPs' prescribing routines.

Sustainability, spread, and scale in trials using audit and feedback: a theory-informed, secondary analysis of a systematic review

BACKGROUND

Audit and feedback (A&F) is a widely used implementation strategy to influence health professionals' behavior that is often tested in implementation trials. This study examines how A&F trials describe sustainability, spread, and scale.

METHODS

This is a theory-informed, descriptive, secondary analysis of an update of the Cochrane systematic review of A&F trials, including all trials published since 2011. Keyword searches related to sustainability, spread, and scale were conducted. Trials with at least one keyword, and those identified from a forward citation search, were extracted to examine how they described sustainability, spread, and scale. Results were qualitatively analyzed using the Integrated Sustainability Framework (ISF) and the Framework for Going to Full Scale (FGFS).

RESULTS

From the larger review, n = 161 studies met eligibility criteria. Seventy-eight percent (n = 126) of trials included at least one keyword on sustainability, and 49% (n = 62) of those studies (39% overall) frequently mentioned sustainability based on inclusion of relevant text in multiple sections of the paper. For spread/scale, 62% (n = 100) of trials included at least one relevant keyword and 51% (n = 51) of those studies (31% overall) frequently mentioned spread/scale. A total of n = 38 studies from the forward citation search were included in the qualitative analysis. Although many studies mentioned the need to consider sustainability, there was limited detail on how this was planned, implemented, or assessed. The most frequent sustainability period duration was 12 months. Qualitative results mapped to the ISF, but not all determinants were represented. Strong alignment was found with the FGFS for phases of scale-up and support systems (infrastructure), but not for adoption mechanisms. New spread/scale themes included (1) aligning affordability and scalability; (2) balancing fidelity and scalability; and (3) balancing effect size and scalability.

CONCLUSION

A&F trials should plan for sustainability, spread, and scale so that if the trial is effective, the benefits can continue. A deeper empirical understanding of the factors impacting A&F sustainability is needed. Scalability planning should go beyond cost and infrastructure to consider other adoption mechanisms, such as leadership, policy, and communication, that may support further scalability.

Best practice guidance for antibiotic audit and feedback interventions in primary care: a modified Delphi study from the Joint Programming Initiative on Antimicrobial resistance: Primary Care Antibiotic Audit and Feedback Network (JPIAMR-PAAN)

BACKGROUND

Primary care is a critical partner for antimicrobial stewardship efforts given its high human antibiotic usage. Peer comparison audit and feedback (A&F) is often used to reduce inappropriate antibiotic prescribing. The design and implementation of A&F may impact its effectiveness. There are no best practice guidelines for peer comparison A&F in antibiotic prescribing in primary care.

OBJECTIVE

To develop best practice guidelines for peer comparison A&F for antibiotic prescribing in primary care in high income countries by leveraging international expertise via the Joint Programming Initiative on Antimicrobial Resistance-Primary Care Antibiotic Audit and Feedback Network.

METHODS

We used a modified Delphi process to achieve convergence of expert opinions on best practice statements for peer comparison A&F based on existing evidence and theory. Three rounds were performed, each with online surveys and virtual meetings to enable discussion and rating of each best practice statement. A five-point Likert scale was used to rate consensus with a median threshold score of 4 to indicate a consensus statement.

RESULTS

The final set of guidelines include 13 best practice statements in four categories: general considerations (n = 3), selecting feedback recipients (n = 1), data and indicator selection (n = 4), and feedback delivery (n = 5).

CONCLUSION

We report an expert-derived best practice recommendations for designing and evaluating peer comparison A&F for antibiotic prescribing in primary care. These 13 statements can be used by A&F designers to optimize the impact of their quality improvement interventions, and improve antibiotic prescribing in primary care.

Effect of Antibiotic Prescription Audit and Feedback on Antibiotic Prescribing in Primary Care: A Randomized Clinical Trial

Importance

Antibiotics are commonly prescribed in primary care, increasing the risk of antimicrobial resistance in the population.

Objective

To investigate the effect of quarterly audit and feedback on antibiotic prescribing among primary care physicians in Switzerland with medium to high antibiotic prescription rates.

Design, Setting, and Participants

This pragmatic randomized clinical trial was conducted from January 1, 2018, to December 31, 2019, among 3426 registered primary care physicians and pediatricians in single or small practices in Switzerland who were among the top 75% prescribers of antibiotics. Intention-to-treat analysis was performed using analysis of covariance models and conducted from September 1, 2021, to January 31, 2022.

Interventions

Primary care physicians were randomized in a 1:1 fashion to undergo quarterly antibiotic prescribing audit and feedback with peer benchmarking vs no intervention for 2 years, with 2017 used as the baseline year. Anonymized patient-level claims data from 3 health insurers serving roughly 50% of insurees in Switzerland were used for audit and feedback. The intervention group also received evidence-based guidelines for respiratory tract and urinary tract infection management and community antibiotic resistance information. Physicians in the intervention group were blinded regarding the nature of the trial, and physicians in the control group were not informed of the trial.

Main Outcomes and Measures

The claims data used for audit and feedback were analyzed to assess outcomes. Primary outcome was the antibiotic prescribing rate per 100 consultations during the second year of the intervention. Secondary end points included overall antibiotic use in the first year and over 2 years, use of quinolones and oral cephalosporins, all-cause hospitalizations, and antibiotic use in 3 age groups.

Results

A total of 3426 physicians were randomized to the intervention (n = 1713) and control groups (n = 1713) serving 629 825 and 622 344 patients, respectively, with a total of 4 790 525 consultations in the baseline year of 2017. In the entire cohort, a 4.2% (95% CI, 3.9%-4.6%) relative increase in the antibiotic prescribing rate was noted during the second year of the intervention compared with 2017. In the intervention group, the median annual antibiotic prescribing rate per 100 consultations was 8.2 (IQR, 6.1-11.4) in the second year of the intervention and was 8.4 (IQR, 6.0-11.8) in the control group. Relative to the overall increase, a -0.1% (95% CI, -1.2% to 1.0%) lower antibiotic prescribing rate per 100 consultations was found in the intervention group compared with the control group. No relevant reductions in specific antibiotic prescribing rates were noted between groups except for quinolones in the second year of the intervention (-0.9% [95% CI, -1.5% to -0.4%]).

Conclusions and Relevance

This randomized clinical trial found that quarterly personalized antibiotic prescribing audit and feedback with peer benchmarking did not reduce antibiotic prescribing among primary care physicians in Switzerland with medium to high antibiotic prescription rates.

Characterizing the Gaps Between Best-Practice Implementation Strategies and Real-world Implementation: Qualitative Study Among Family Physicians Who Engaged With Audit and Feedback Reports

BACKGROUND

In Ontario, Canada, a government agency known as Ontario Health is responsible for making audit and feedback reports available to all family physicians to encourage ongoing quality improvement. The confidential report provides summary data on 3 key areas of practice: safe prescription, cancer screening, and diabetes management.

OBJECTIVE

This report was redesigned to improve its usability in line with evidence. The objective of this study was to explore how the redesign was perceived, with an emphasis on recipients' understanding of the report and their engagement with it.

METHODS

We conducted qualitative semistructured interviews with family physicians who had experience with both versions of the report recruited through purposeful and snowball sampling. We analyzed the transcripts following an emergent and iterative approach.

RESULTS

Saturation was reached after 17 family physicians participated. In total, 2 key themes emerged as factors that affected the perceived usability of the report: alignment between the report and the recipients' expectations and capacity to engage in quality improvement. Family physicians expected the report and its quality indicators to reflect best practices and to be valid and accurate. They also expected the report to offer feedback on the clinical activities they perceived to be within their control to change. Furthermore, family physicians expected the goal of the report to be aligned with their perspective on feasible quality improvement activities. Most of these expectations were not met, limiting the perceived usability of the report. The capacity to engage with audit and feedback was hindered by several organizational and physician-level barriers, including the lack of fit with the existing workflow, competing priorities, time constraints, and insufficient skills for bridging the gaps between their data and the corresponding desired actions.

CONCLUSIONS

Despite recognized improvements in the design of the report to better align with best practices, it was not perceived as highly usable. Improvements in the presentation of the data could not overcome misalignment with family physicians' expectations or the limited capacity to engage with the report. Integrating iterative evaluations informed by user-centered design can complement evidence-based guidance for implementation strategies. Creating a space for bringing together audit and feedback designers and recipients may help improve usability and effectiveness.

Comparing antibiotic prescriptions in primary care between SARS-CoV-2 and influenza: a retrospective observational study

BACKGROUND

Antibiotics are frequently prescribed during viral respiratory infection episodes in primary care. There is limited information about antibiotic prescription during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic in primary care and its association with risk factors for an adverse course.

AIM

To compare the proportion of antibiotic prescriptions between patients with COVID-19 and influenza or influenza-like symptoms, and to assess the association between antibiotic prescriptions and risk factors for an adverse course of COVID-19.

DESIGN & SETTING

An observational cohort study using pseudonymised and coded routine healthcare data extracted from 85 primary care practices in the Netherlands.

METHOD

Adult patients with influenza and influenza-like symptoms were included from the 2017 influenza season to the 2020 season. Adult patients with suspected or confirmed COVID-19 were included from the first (15 February 2020-1 August 2020) and second (1 August 2020-1 January 2021) SARS-CoV-2 waves. Proportions of antibiotic prescriptions were calculated for influenza and COVID-19 patients. Odds ratios (ORs) were used to compare the associations of antibiotic prescriptions in COVID-19 patients with risk factors, hospital admission, intensive care unit (ICU) admission, and mortality.

RESULTS

The proportion of antibiotic prescriptions during the first SARS-CoV-2 wave was lower than during the 2020 influenza season (9.6% versus 20.7%), difference 11.1% (95% confidence interval [CI] = 8.7 to 13.5). During the second SARS-CoV-2 wave, antibiotic prescriptions were associated with being aged ≥70 years (OR 2.05; 95% CI = 1.43 to 2.93), the number of comorbidities (OR 1.46; 95% CI = 1.18 to 1.82), and admission to hospital (OR 3.19; 95% CI = 2.02 to 5.03) or ICU (OR 4.64; 95% CI = 2.02 to 10.62).

CONCLUSION

Antibiotic prescription was less common during the SARS-CoV-2 pandemic than during influenza seasons, and was associated with an adverse course and its risk factors. The findings suggest a relatively targeted prescription policy of antibiotics in primary care during COVID-19.

The use of postal audit and feedback among Irish General Practitioners for the self – management of antimicrobial prescribing: a qualitative study

Objective

Inappropriate use of antibiotics has been acknowledged as a significant contributor to the proliferation of antimicrobial resistance worldwide. Physician prescribing of antibiotics has been identified as a factor in the inappropriate use of antibiotics. One methodology that is used in an attempt to alter physician prescribing behaviours is audit and feedback. This study aimed to explore the perceptions of Irish General Practitioners (GPs) towards the national introduction of postal feedback on their antibiotic prescribing behaviours beginning in 2019.

Design

A qualitative descriptive methodology was used. Semi–structured interviews were conducted with GPs in receipt of postal audit and feedback.

Method

GPs working in Ireland and in receipt of postal audit and feedback on their antibiotic prescribing behaviours participated in phone-based interviews. The interviews were recorded and transcribed verbatim. The collected data was then analysed using an inductive thematic analysis.

Results

Twelve GPs participated in the study (female = 5). Three themes were identified from the analysis. The themes identified were the reliability and validity of the feedback received, feedback on antibiotic prescribing is useful but limited and feedback needs to be easily digestible.

Conclusion

While the postal audit and feedback were broadly welcomed by the participants, the themes identified a perceived limitation in the quality of the feedback data, the perception of a likely low public health impact of the feedback and difficulties with efficiently processing the audit and feedback information. These findings can help refine future audit and feedback interventions on antibiotic prescribing.

A Baker's Dozen of Top Antimicrobial Stewardship Intervention Publications in Non-Hospital Care Settings in 2021

The scope of antimicrobial stewardship programs has expanded beyond the acute hospital setting. The need to optimize antimicrobial use in emergency departments, urgent, primary, and specialty care clinics, nursing homes, and long-term care facilities prompted the development of core elements of stewardship programs in these settings. Identifying the most innovative and well-designed stewardship literature in these novel stewardship areas can be challenging. The Southeastern Research Group Endeavor (SERGE-45) network evaluated antimicrobial stewardship-related, peer-reviewed literature published in 2021 that detailed actionable interventions specific to the nonhospital setting. The top 13 publications were summarized following identification using a modified Delphi technique. This article highlights the selected interventions and may serve as a key resource for expansion of antimicrobial stewardship programs beyond the acute hospital setting.

Effect of unifaceted and multifaceted interventions on antibiotic prescription control for respiratory diseases: A systematic review of randomized controlled trials

BACKGROUND

The global health system is improperly using antibiotics, particularly in the treatment of respiratory diseases. We aimed to examine the effectiveness of implementing a unifaceted and multifaceted intervention for unreasonable antibiotic prescriptions.

METHODS

Relevant literature published in the databases of Pubmed, Embase, Science Direct, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure and Wanfang was searched. Data were independently filtered and extracted by 2 reviewers based on a pre-designed inclusion and exclusion criteria. The Cochrane collaborative bias risk tool was used to evaluate the quality of the included randomized controlled trials studies.

RESULTS

A total of 1390 studies were obtained of which 23 studies the outcome variables were antibiotic prescription rates with the number of prescriptions and intervention details were included in the systematic review. Twenty-two of the studies involved educational interventions for doctors, including: online training using email, web pages and webinar, antibiotic guidelines for information dissemination measures by email, postal or telephone reminder, training doctors in communication skills, short-term interactive educational seminars, and short-term field training sessions. Seventeen studies of interventions for health care workers also included: regular or irregular assessment/audit of antibiotic prescriptions, prescription recommendations from experts and peers delivered at a meeting or online, publicly reporting on doctors' antibiotic usage to patients, hospital administrators, and health authorities, monitoring/feedback prescribing behavior to general practices by email or poster, and studies involving patients and their families (n = 8). Twenty-one randomized controlled trials were rated as having a low risk of bias while 2 randomized controlled trials were rated as having a high risk of bias. Six studies contained negative results.

CONCLUSION

The combination of education, prescription audit, prescription recommendations from experts, public reporting, prescription feedback and patient or family member multifaceted interventions can effectively reduce antibiotic prescription rates in health care institutions. Moreover, adding multifaceted interventions to educational interventions can control antibiotic prescription rates and may be a more reasonable method.

Promoting rational antibiotic therapy among high antibiotic prescribers in German primary care-study protocol of the ElektRA 4-arm cluster-randomized controlled trial

Background

The rational use of antibiotics is of great importance in health care. In primary care, acute respiratory infections are the most common cause of inappropriate antibiotic prescribing. Since existing studies aiming to optimize antibiotic use are usually based on the voluntary participation of physicians, general practitioners (GPs) with inappropriate prescribing behavior are underrepresented. For the first time in Germany, the ElektRA study will assess and compare the effects of three interventions on antibiotic prescribing rates for respiratory and urinary tract infections among high prescribers in primary care.

Method

ElektRA is a 4-arm cluster-randomized controlled trial among German GPs in nine regional Associations of Statutory Health Insurance Physicians. On their behalf, the Central Research Institute of Ambulatory Health Care in Germany (Zi) analyses all outpatient claims and prescription data. Based on this database, high antibiotic prescribing GPs are identified and randomized into four groups: a control group (N=2000) and three intervention arms. We test social norm feedback on antibiotic prescribing (N=2000), social norm feedback plus online training on rational prescribing practice and communication strategies (N=2000), and social norm feedback plus online peer-moderated training on rational antibiotic prescribing, communication strategies, and sustainable behavior change (N=1250). The primary outcome is the overall rate of antibiotic prescriptions. Outcomes are measured before intervention (T0, October 2020–September 2022) and over a period of 15 months (T1, October 2022 to December 2023) after randomization.

Discussion

The aim of the study is to implement individualized, low-threshold interventions to reduce antibiotic prescribing among high prescribers in primary care. If successful, a change in behavior among otherwise difficult-to-reach high prescribers will directly improve patient care. The increase in quality of care will ideally be achieved both in terms of the quantity of antibiotics used as well as the kind of substances prescribed. Also, if effective strategies for high prescribers are identified through this study, they can be applied not only to the antibiotics addressed in this study, but also to other areas of prescription management.

Sustainability of healthcare professionals' adherence to clinical practice guidelines in primary care

BACKGROUND

Sustainability of adherence to clinical practice guidelines (CPGs) represents an important indicator of the successful implementation in the primary care setting.

AIM

To explore the sustainability of primary care providers' adherence to CPGs after receiving planned guideline implementation strategies, activities, or programmes.

METHODS

Cochrane Central Register of Controlled Trials (CENTRAL); Cumulative Index to Nursing and Allied Health Literature (CINAHL); EMBase; Joanna Briggs Institute; Journals@Ovid; Medline; PsycoINFO; PubMed, and Web of Science were searched from January 2000 through May 2021 to identify relevant studies. Studies evaluating the sustainability of primary care providers' (PCPs') adherence to CPGs in primary care after any planned guideline implementation strategies, activities, or programmes were included. Two reviewers extracted data from the included studies and assessed methodological quality independently. Narrative synthesis of the findings was conducted.

RESULTS

Eleven studies were included. These studies evaluated the sustainability of adherence to CPGs related to drug prescribing, disease management, cancer screening, and hand hygiene in primary care. Educational outreach visits, teaching sessions, reminders, audit and feedback, and printed materials were utilized in the included studies as guideline implementation strategies. None of the included studies utilized purpose-designed measurements to evaluate the extent of sustainability. Three studies showed positive sustainability results, three studies showed mixed sustainability results, and four studies reported no significant changes in the sustainability of adherence to CPGs. Overall, it was difficult to quantify the extent to which CPG-based healthcare behaviours were fully sustained based on the variety of results reported in the included studies.

CONCLUSION

Current guideline implementation strategies may potentially improve the sustainability of PCPs' adherence to CPGs. However, the literature reveals a limited body of evidence for any given guideline implementation strategy. Further research, including the development of a validated purpose-designed sustainability tool, is required to address this important clinical issue.

Changing antibiotic prescribing practices in outpatient primary care settings in China: Study protocol for a health information system-based cluster-randomised crossover controlled trial

Background

The overuse and abuse of antibiotics is a major risk factor for antibiotic resistance in primary care settings of China. In this study, the effectiveness of an automatically-presented, privacy-protecting, computer information technology (IT)-based antibiotic feedback intervention will be evaluated to determine whether it can reduce antibiotic prescribing rates and unreasonable prescribing behaviours.

Methods

We will pilot and develop a cluster-randomised, open controlled, crossover, superiority trial. A total of 320 outpatient physicians in 6 counties of Guizhou province who met the standard will be randomly divided into intervention group and control group with a primary care hospital being the unit of cluster allocation. In the intervention group, the three components of the feedback intervention included: 1. Artificial intelligence (AI)-based real-time warnings of improper antibiotic use; 2. Pop-up windows of antibiotic prescription rate ranking; 3. Distribution of educational manuals. In the control group, no form of intervention will be provided. The trial will last for 6 months and will be divided into two phases of three months each. The two groups will crossover after 3 months. The primary outcome is the 10-day antibiotic prescription rate of physicians. The secondary outcome is the rational use of antibiotic prescriptions. The acceptability and feasibility of this feedback intervention study will be evaluated using both qualitative and quantitative assessment methods.

Discussion

This study will overcome limitations of our previous study, which only focused on reducing antibiotic prescription rates. AI techniques and an educational intervention will be used in this study to effectively reduce antibiotic prescription rates and antibiotic irregularities. This study will also provide new ideas and approaches for further research in this area.

Reducing antibiotic prescribing by enhancing communication of general practitioners with their immigrant patients: protocol for a randomised controlled trial (PARCA study)

INTRODUCTION

Although antibiotic use and antimicrobial resistance in the Netherlands is comparatively low, inappropriate prescription of antibiotics is substantial, mainly for respiratory tract infections (RTIs). General practitioners (GPs) experience pressure from patients with an immigration background to prescribe antibiotics and have difficulty communicating in a culturally sensitive way. Multifaceted interventions including communication skills training for GPs are shown to be most effective in reducing antibiotic prescription. The PARCA study aims to reduce the number of antibiotic prescriptions for RTIs through implementing a culturally sensitive communication intervention for GPs and evaluate it in a randomised controlled trial (RCT).

METHODS AND ANALYSIS

A non-blinded RCT including 58 GPs (29 for each arm). The intervention consists of: (1) An E-learning with 4 modules of 10-15 min each; (2) A face-to-face training session in (intercultural) communication skills including role plays with a training actor and (3) Availability of informative patient-facing materials that use simple words (A2/B1 level) in multiple languages. The primary outcome measure is the number of dispensed antibiotic courses qualifying for RTIs in primary care, per 1000 registered patients. The secondary outcome measure is the number of all dispensed antibiotic courses, per 1000 registered patients. The intervention arm will receive the training in Autumn 2021, followed by an observation period of 6 winter months for which numbers of antibiotics will be collected for both trial arms. The GPs/practices in the control arm can attend the training after the observation period.

ETHICS AND DISSEMINATION

The study protocol was approved by the Medical Ethics Review Committee of Erasmus MC, University Medical Center Rotterdam (MEC-2020-0142). The results of the trial will be published in international peer-reviewed scientific journals and will be disseminated through national and international congresses. The project is funded by The Netherlands Organisation for Health Research and Development (ZonMw).

A pragmatic randomized trial of a primary care antimicrobial stewardship intervention in Ontario, Canada

BACKGROUND

More than 90% of antibiotics are prescribed in primary care, but 50% may be unnecessary. Reducing unnecessary antibiotic overuse is needed to limit antimicrobial resistance. We conducted a pragmatic trial of a primary care provider-focused antimicrobial stewardship intervention to reduce antibiotic prescriptions in primary care.

METHODS

Primary care practitioners from six primary care clinics in Toronto, Ontario were assigned to intervention or control groups to evaluate the effectiveness of a multi-faceted intervention for reducing antibiotic prescriptions to adults with respiratory and urinary tract infections. The intervention included provider education, clinical decision aids, and audit and feedback of antibiotic prescribing. The primary outcome was total antibiotic prescriptions for these infections. Secondary outcomes were delayed prescriptions, prescriptions longer than 7 days, recommended antibiotic use, and outcomes for individual infections. Generalized estimating equations were used to estimate treatment effects, adjusting for clustering by clinic and baseline differences.

RESULTS

There were 1682 encounters involving 54 primary care providers from January until May 31, 2019. In intervention clinics, the odds of any antibiotic prescription was reduced 22% (adjusted Odds Ratio (OR) = 0.78; 95% Confidence Interval (CI) = 0.64.0.96). The odds that a delay in filling a prescription was recommended was increased (adjusted OR=2.29; 95% CI=1.37, 3.83), while prescription durations greater than 7 days were reduced (adjusted OR=0.24; 95% CI=0.13, 0.43). Recommended antibiotic use was similar in control (85.4%) and intervention clinics (91.8%, p=0.37).

CONCLUSIONS

A community-based, primary care provider-focused antimicrobial stewardship intervention was associated with a reduced likelihood of antibiotic prescriptions for respiratory and urinary infections, an increase in delayed prescriptions, and reduced prescription durations.

Evidence-based public policy making for medicines across countries: findings and implications for the future

Aim: Global expenditure on medicines is rising up to 6% per year driven by increasing prevalence of non-communicable diseases (NCDs) and new premium priced medicines for cancer, orphan diseases and other complex areas. This is difficult to sustain without reforms. Methods: Extensive narrative review of published papers and contextualizing the findings to provide future guidance. Results: New models are being introduced to improve the managed entry of new medicines including managed entry agreements, fair pricing approaches and monitoring prescribing against agreed guidance. Multiple measures have also successfully been introduced to improve the prescribing of established medicines. This includes encouraging greater prescribing of generics and biosimilars versus originators and patented medicines in a class to conserve resources without compromising care. In addition, reducing inappropriate antibiotic utilization. Typically, multiple measures are the most effective. Conclusion: Multiple measures will be needed to attain and retain universal healthcare.

Community antibiotic prescribing for children in France from 2015 to 2017: a cross-sectional national study

OBJECTIVES

To assess recent community antibiotic prescribing for French children and identify areas of potential improvement.

METHODS

We analysed 221 768 paediatric (<15 years) visits in a national sample of 680 French GPs and 70 community paediatricians (IQVIA's EPPM database), from March 2015 to February 2017, excluding well-child visits. We calculated antibiotic prescription rates per 100 visits, separately for GPs and paediatricians. For respiratory tract infections (RTIs), we described broad-spectrum antibiotic use and duration of treatment. We used Poisson regression to identify factors associated with antibiotic prescribing.

RESULTS

GPs prescribed more antibiotics than paediatricians [prescription rate 26.1 (95% CI 25.9-26.3) versus 21.6 (95% CI 21.0-22.2) per 100 visits, respectively; P < 0.0001]. RTIs accounted for more than 80% of antibiotic prescriptions, with presumed viral RTIs being responsible for 40.8% and 23.6% of all antibiotic prescriptions by GPs and paediatricians, respectively. For RTIs, antibiotic prescription rates per 100 visits were: otitis, 68.1 and 79.8; pharyngitis, 67.3 and 53.3; sinusitis, 67.9 and 77.3; pneumonia, 80.0 and 99.2; bronchitis, 65.2 and 47.3; common cold, 21.7 and 11.6; bronchiolitis 31.6 and 20.1; and other presumed viral RTIs, 24.1 and 11.0, for GPs and paediatricians, respectively. For RTIs, GPs prescribed more broad-spectrum antibiotics [49.8% (95% CI 49.3-50.3) versus 35.6% (95% CI 34.1-37.1), P < 0.0001] and antibiotic courses of similar duration (P = 0.21). After adjustment for diagnosis, antibiotic prescription rates were not associated with season and patient age, but were significantly higher among GPs aged ≥50 years.

CONCLUSIONS

Future antibiotic stewardship campaigns should target presumed viral RTIs, broad-spectrum antibiotic use and GPs aged ≥50 years.

Safety review of current systemic treatments for severe chronic rhinosinusitis with nasal polyps and future directions

Introduction: Chronic rhinosinusitis is a common condition characterized by inflammation of the nasal and sinus linings, rhinorrhea, nasal blockage, facial pain, and loss of sense of smell for longer than 12 weeks. CRS can occur with or without nasal polyps.Areas covered: First-line treatment in chronic rhinosinusitis with nasal polyps is long-term intranasal corticosteroids, which have few adverse events associated with their use, as second-generation intranasal corticosteroids having a bioavailability of <0.5%. Systemic corticosteroids are used when intranasal steroids fail to achieve symptom control. However, the repeated use of oral corticosteroids is associated with numerous adverse events and the benefit from a course of oral corticosteroids is lost within three to six months.Expert opinion: Antibiotics are commonly prescribed in nasal polyposis although there is also very little evidence for their use outside of acute infection. Macrolide antibiotics are also associated with a transient increase in the risk of arrhythmias. Biologics offer a steroid-sparing alternative to the treatment of severe nasal polyposis. They have shown to be relatively well tolerated in studies to date; however, studies suggest that there is no disease modifying effect and that any benefit is lost within weeks of finishing treatment.

Impact of a Social Marketing Intervention on General Practitioners' Antibiotic Prescribing Practices for Acute Respiratory Tract Complaints in Malta

Introduction: Antibiotics are commonly prescribed in primary care for acute respiratory tract complaints (aRTCs), often inappropriately. Social marketing interventions could improve prescribing in such settings. We evaluate the impact of a social marketing intervention on general practitioners' (GPs') antibiotic prescribing for aRTCs in Malta. Methods: Changes in GPs' antibiotic prescribing were monitored over two surveillance periods between 2015 and 2018. Primary outcome: change in antibiotic prescription for aRTCs. Secondary outcomes: change in antibiotic prescription: (i) for immediate use, (ii) for delayed antibiotic prescription, (iii) by diagnosis, and (iv) by antibiotic class. Data were analysed using clustered analysis and interrupted time series analysis (ITSA). Results: Of 33 participating GPs, 18 successfully completed the study. Although clustered analyses showed a significant 3% decrease in overall antibiotic prescription (p = 0.024), ITSA showed no significant change overall (p = 0.264). Antibiotic prescription decreased significantly for the common cold (p < 0.001), otitis media (p = 0.044), and sinusitis (p = 0.004), but increased for pharyngitis (p = 0.015). Conclusions: The intervention resulted in modest improvements in GPs' antibiotic prescribing. A more top-down approach will likely be required for future initiatives to be successful in this setting, focusing on diagnostic and prescribing support like rapid diagnostic testing, prescribing guidelines, and standardised delayed antibiotic prescriptions.

Patients receiving a high burden of antibiotics in the community in Spain: a cross-sectional study

Some patients in the community receive a high burden of antibiotics. We aimed at describing the characteristics of these patients, antibiotics used, and conditions for which they received antibiotics. We carried out a cross-sectional study. Setting: Thirty Health Primary Care Areas from 12 regions in Spain, covering 5,960,191 inhabitants. Patients having at least 30 packages of antibacterials for systemic use dispensed in 2017 were considered. Main outcome measures: Prevalence of antibiotic use, conditions for which antibiotics were prescribed, clinical characteristics of patients, comorbidities, concomitant treatments, and microbiological isolates. Patient's average age was 70 years; 52% were men; 60% smokers/ex-smokers; 54% obese. Overall, 93% of patients had, at least, one chronic condition, and four comorbidities on average. Most common comorbidities were cardiovascular and/or hypertension (67%), respiratory diseases (62%), neurological/mental conditions (32%), diabetes (23%), and urological diseases (21%); 29% were immunosuppressed, 10% were dead at the time of data collection. Patients received three antibiotic treatments per year, mainly fluoroquinolones (28%), macrolides (21%), penicillins (19%), or cephalosporins (12%). Most frequently treated conditions were lower respiratory tract (infections or prophylaxis) (48%), urinary (27%), and skin/soft tissue infections (11%). Thirty-five percent have been guided by a microbiological diagnosis, being Pseudomonas aeruginosa (30%) and Escherichia coli (16%) the most frequent isolates. In conclusion, high antibiotic consumers in the community were basically elder, with multimorbidity and polymedication. They frequently received broad-spectrum antibiotics for long periods of time. The approach to infections in high consumers should be differentiated from healthy patients receiving antibiotics occasionally.

Impact of a multifaceted intervention to improve antibiotic prescribing: a pragmatic cluster-randomised controlled trial

OBJECTIVES

This study sought to assess the effectiveness and return on investment (ROI) of a multifaceted intervention aimed at improving antibiotic prescribing for acute respiratory infections in primary care.

DESIGN

Large-sized, two-arm, open-label, pragmatic, cluster-randomised controlled trial.

SETTING

All primary care physicians working for the Spanish National Health Service (NHS) in Galicia (region in north-west Spain).

PARTICIPANTS

The seven spatial clusters were distributed by unequal randomisation (3:4) of the intervention and control groups. A total of 1217 physicians (1.30 million patients) were recruited from intervention clusters and 1393 physicians (1.46 million patients) from control clusters.

INTERVENTIONS

One-hour educational outreach visits tailored to training needs identified in a previous study; an online course integrated in practice accreditation; and a clinical decision support system.

MAIN OUTCOME MEASURES

Changes in the ESAC (European Surveillance of Antimicrobial Consumption) quality indicators for outpatient antibiotic use. We used generalised linear mixed and conducted a ROI analysis to ascertain the overall cost savings.

RESULTS

Median follow-up was 19 months. The adjusted effect on overall antibiotic prescribing attributable to the intervention was - 4.2% (95% CI: - 5.3% to - 3.2%), with this being more pronounced for penicillins - 6.5 (95% CI: - 7.9% to - 5.2%) and for the ratio of consumption of broad- to narrow-spectrum penicillins, cephalosporins, and macrolides - 9.0% (95% CI: - 14.0 to - 4.1%). The cost of the intervention was €87 per physician. Direct savings per physician attributable to the reduction in antibiotic prescriptions was €311 for the NHS and €573 for patient contributions, with an ROI of €2.57 and €5.59 respectively.

CONCLUSIONS

Interventions designed on the basis of gaps in physicians' knowledge of and attitudes to misprescription can improve antibiotic prescribing and yield important direct cost savings.

Management of non-urgent paediatric emergency department attendances by GPs: a retrospective observational study

Background

Non-urgent emergency department (ED) attendances are common among children. Primary care management may not only be more clinically appropriate, but may also improve patient experience and be more cost-effective.

Aim

To determine the impact on admissions, waiting times, antibiotic prescribing, and treatment costs of integrating a GP into a paediatric ED.

Design and setting

Retrospective cohort study explored non-urgent ED presentations in a paediatric ED in north-west England.

Method

From 1 October 2015 to 30 September 2017, a GP was situated in the ED from 2.00 pm until 10.00 pm, 7 days a week. All children triaged as ‘green’ using the Manchester Triage System (non-urgent) were considered to be ‘GP appropriate’. In cases of GP non-availability, children considered non-urgent were managed by ED staff. Clinical and operational outcomes, as well as the healthcare costs of children managed by GPs and ED staff across the same timeframe over a 2-year period were compared.

Results

Of 115 000 children attending the ED over the study period, a complete set of data were available for 13 099 categorised as ‘GP appropriate’; of these, 8404 (64.2%) were managed by GPs and 4695 (35.8%) by ED staff. Median duration of ED stay was 39 min (interquartile range [IQR] 16–108 min) in the GP group and 165 min (IQR 104–222 min) in the ED group (P<0.001). Children in the GP group were less likely to be admitted as inpatients (odds ratio [OR] 0.16; 95% confidence interval [CI] = 0.13 to 0.20) and less likely to wait >4 hours before being admitted or discharged (OR 0.11; 95% CI = 0.08 to 0.13), but were more likely to receive antibiotics (OR 1.42; 95% CI = 1.27 to 1.58). Treatment costs were 18.4% lower in the group managed by the GP (P<0.0001).

Conclusion

Given the rising demand for children’s emergency services, GP in ED care models may improve the management of non-urgent ED presentations. However, further research that incorporates causative study designs is required.

Accuracy of signs, symptoms and blood tests for diagnosing acute bacterial rhinosinusitis and CT-confirmed acute rhinosinusitis in adults: protocol of an individual patient data meta-analysis

INTRODUCTION

This protocol outlines a diagnostic individual patient data (IPD) meta-analysis aimed at developing simple prediction models based on readily available signs, symptoms and blood tests to accurately predict acute bacterial rhinosinusitis and CT-confirmed (fluid level or total opacification in any sinus) acute rhinosinusitis (ARS) in adults presenting to primary care with clinically diagnosed ARS, target conditions associated with antibiotic benefit.

METHODS AND ANALYSIS

The systematic searches of PubMed and Embase of a review on the accuracy of signs and symptoms for diagnosing ARS in ambulatory care will be updated to April 2020 to identify relevant studies. Authors of eligible studies will be contacted and invited to provide IPD. Methodological quality of the studies will be assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 tool. Candidate predictor selection will be based on knowledge from existing literature, clinical reasoning and availability. Multivariable logistic regression analyses will be used to develop prediction models aimed at calculating absolute risk estimates. Large unexplained between-study heterogeneity in predictive accuracy of the models will be explored and may lead to either model adjustment or derivation of separate context-specific models. Calibration and discrimination will be evaluated to assess the models' performance. Bootstrap resampling techniques will be used to assess internal validation and to inform on possible adjustment for overfitting. In addition, we aim to perform internal-external cross-validation procedures.

ETHICS AND DISSEMINATION

In this IPD meta-analysis, no identifiable patient data will be used. As such, the Medical Research Involving Humans Subject Act does not apply, and official ethical approval is not required. Findings will be published in international peer-reviewed journals and presented at scientific conferences.

The effects of the primary health care providers' prescription behavior interventions to improve the rational use of antibiotics: a systematic review

Background

Irrational antibiotics use in clinical prescription, especially in primary health care (PHC) is accelerating the spread of antibiotics resistance (ABR) around the world. It may be greatly useful to improve the rational use of antibiotics by effectively intervening providers' prescription behaviors in PHC. This study aimed to systematically review the interventions targeted to providers' prescription behaviors in PHC and its' effects on improving the rational use of antibiotics.

Methods

The literatures were searched in Ovid Medline, Web of Science, PubMed, Cochrane Library, and two Chinese databases with a time limit from January 1st, 1998 to December 1st, 2018. The articles included in our review were randomized control trial, controlled before-and-after studies and interrupted time series, and the main outcomes measured in these articles were providers' prescription behaviors. The Cochrane Collaboration criteria were used to assess the risk of bias of the studies by two reviewers. Narrative analysis was performed to analyze the effect size of interventions.

Results

A total of 4422 studies were identified in this study and 17 of them were included in the review. Among 17 included studies, 13 studies were conducted in the Europe or in the United States, and the rest were conducted in low-income and-middle-income countries (LMICs). According to the Cochrane Collaboration criteria, 12 studies had high risk of bias and 5 studies had medium risk of bias. There was moderate-strength evidence that interventions targeted to improve the providers' prescription behaviors in PHC decreased the antibiotics prescribing and improved the rational use of antibiotics.

Conclusions

Interventions targeted PHC providers' prescription behaviours could be an effective way to decrease the use of antibiotics in PHC and to promote the rational use of antibiotics. However, we cannot compare the effects between different interventions because of heterogeneity of interventions and outcome measures.

Structural Antibiotic Surveillance and Stewardship via Indication-Linked Quality Indicators: Pilot in Dutch Primary Care

Insight into antibiotic prescribing quality is key to general practitioners (GPs) to improve their prescribing behavior and to national antibiotic surveillance and stewardship programs. Additionally to numbers of prescribed antibiotics, quality indicators (QIs) linked to the clinical indication for prescribing are urgently needed. The aim of this proof of concept study was to define indication-linked QIs which can be easily implemented in Dutch primary care by collaborating with data-extraction/processing companies that routinely process patient data for GP practices. An expert group of academic and practicing GPs defined indication-linked QIs for which outcomes can be derived from routine care data. QI outcomes were calculated and fed back to GPs from 44 practices, associations between QI outcomes were determined, and GPs’ opinions and suggestions with respect to the new set were captured using an online questionnaire. The new set comprises: (1) total number of prescribed antibiotics per 1000 registered patients and percentages of generally non-1st choice antibiotics; (2) prescribing percentages for episodes of upper and lower respiratory tract infection; (3) 1st choice prescribing for episodes of tonsillitis, pneumonia and cystitis in women. Large inter-practice variation in QI outcomes was found. The validity of the QI outcomes was confirmed by associations that were expected. The new set was highly appreciated by GPs and additional QIs were suggested. We conclude that it proved feasible to provide GPs with informative, indication-linked feedback of their antibiotic prescribing quality by collaborating with established data extraction/processing companies. Based on GPs’ suggestions the set will be refined and extended and used in the near future as yearly feedback with benchmarking for GPs and for national surveillance and stewardship purposes.

Systematic Review on the Impact of Guidelines Adherence on Antibiotic Prescription in Respiratory Infections

Overuse and inappropriate antibiotic prescription for respiratory tract infections (RTI) are one of the major contributors to the current antibiotic resistance problem. Guidelines provide support to prescribers for proper decision-making. Our purpose is to review the impact of prescribers' exposure to guidelines in antibiotic prescription for RTIs. A systematic review was performed searching in the scientific databases MEDLINE PubMed and EMBASE for studies which exposed prescribers to guidelines for RTI and compared antibiotic prescription rates/quality before and after the implementation, with thirty-four articles included in the review. The selected studies consisted on a simple intervention in the form of guideline implementation while others involved multifaceted interventions, and varied in population, designs, and settings. Prescription rate was shown to be reduced in the majority of the studies, along with an improvement in appropriateness, defined mainly by the prescription of narrow-spectrum rather than broad-spectrum antibiotics. Intending to ascertain if this implementation could decrease prescription costs, 7 articles accessed it, of which 6 showed the intended reduction. Overall interventions to improve guidelines adherence can be effective in reducing antibiotic prescriptions and inappropriate antibiotic selection for RTIs, supporting the importance of implementing guidelines in order to decrease the high levels of antibiotic prescriptions, and consequently reduce antimicrobial resistance.

The effectiveness of a simple antimicrobial stewardship intervention in general practice in Australia: a pilot study

BACKGROUND

Inappropriate and excessive antimicrobial prescribing can lead to antimicrobial resistance. Antimicrobial Stewardship (AMS) principles are not well established in general practice in Australia despite the relatively high rate of community antimicrobial prescribing. Few interventions have been implemented that have resulted in a significant reduction or improvement in antimicrobial prescribing by General Practitioners (GPs). This study was therefore conducted to assess the impact of a novel GP educational intervention on the appropriateness of antimicrobial prescriptions as well as GP compliance with antimicrobial prescription guidelines.

METHODS

In 2018, a simple GP educational intervention was rolled out in a large clinic with the aim of improving antimicrobial prescribing. It included face-to-face education sessions with GPs on AMS principles, antimicrobial resistance, current prescribing guidelines and microbiological testing. An antibiotic appropriateness audit on prescribing practice before and after the educational intervention was conducted. Data were summarised using percentages and compared across time points using Chi-squared tests and Poisson regression (results reported as risk ratios (RR) with 95% confidence intervals (CI)).

RESULTS

Data from 376 and 369 prescriptions in July 2016 and July 2018, respectively, were extracted. There were significant improvements in appropriate antimicrobial selection (73.9% vs 92.8%, RR = 1.26; 95% CI = 1.18-1.34), appropriate duration (53.1% vs 87.7%, RR = 1.65; 95% CI = 1.49-1.83) and compliance with guidelines (42.2% vs 58.5%, RR = 1.39, 95% CI = 1.19-1.61) post- intervention. Documentation of antimicrobial duration directions, patient follow-up as well as patient weight significantly increased after the intervention (p < 0.001). There was significant reduction in; prescriptions without a listed indication for antimicrobial therapy, prescriptions without appropriate accompanying microbiological tests and the provision of unnecessary repeat prescriptions (p < 0.001). Inappropriate antimicrobial prescriptions observed pre-intervention for medical termination of pregnancy ceased post-intervention.

CONCLUSIONS

Auditing GP antimicrobial prescriptions identified prescribing practices inconsistent with Australian guidelines. However, implementation of a simple education program led to significantly improved antimicrobial prescribing by GPs. These findings indicate the important role of AMS and continued antimicrobial education within general practice.

Practice-Level Association between Antibiotic Prescribing and Resistance: An Observational Study in Primary Care

A direct relation between antibiotic use and resistance has been shown at country level. We aim to investigate the association between antibiotic prescribing for patients from individual Dutch primary care practices and antibiotic resistance of bacterial isolates from routinely submitted urine samples from their patient populations. Practices' antibiotic prescribing data were obtained from the Julius Network and related to numbers of registered patients. Practices were classified as low-, middle- or high-prescribers and from each group size-matching practices were chosen. Culture and susceptibility data from submitted urine samples were obtained from the microbiology laboratory. Percentages of resistant isolates, and resistant isolates per 1000 registered patients per year (population resistance) were calculated and compared between the groups. The percentages of resistant Escherichia coli varied considerably between individual practices, but the three prescribing groups' means were very similar. However, as the higher-prescribing practices requested more urine cultures per 1000 registered patients, population resistance was markedly higher in the higher-prescribing groups. This study showed that the highly variable resistance percentages for individual practices were unrelated to antibiotic prescribing levels. However, population resistance (resistant strains per practice population) was related to antibiotic prescribing levels, which was shown to coincide with numbers of urine culture requests. Whether more urine culture requests in the higher-prescribing groups were related to treatment failures, more complex patient populations, or to general practitioners' testing behaviour needs further investigation.

Targets for the reduction of antibiotic use in humans in the Transatlantic Taskforce on Antimicrobial Resistance (TATFAR) partner countries

Unnecessary and inappropriate use of antibiotics in human healthcare is a major driver for the development and spread of antimicrobial resistance; many countries are implementing measures to limit the overuse and misuse of antibiotics e.g. through the establishment of antimicrobial use reduction targets. We performed a review of antimicrobial use reduction goals in human medicine in Transatlantic Taskforce on Antimicrobial Resistance partner countries. On 31 March 2017, the European Centre for Disease Prevention and Control sent a questionnaire to National Focal Points for Antimicrobial Consumption and the National Focal Points for Antimicrobial Resistance in 28 European Union countries, Iceland and Norway. The same questionnaire was sent to the TATFAR implementers in Canada and the United States. Thirty of 32 countries replied. Only nine countries indicated that they have established targets to reduce antimicrobial use in humans. Twenty-one countries replied that no target had been established. However, 17 of these 21 countries indicated that work to establish such targets is currently underway, often in the context of developing a national action plan against antimicrobial resistance. The reported targets varied greatly between countries and can be a useful resource for countries willing to engage in the reduction of antibiotic use in humans.

Antimicrobial stewardship in the primary care setting: from dream to reality?

BACKGROUND

Clinicians who work in primary care are potentially the most influential healthcare professionals to address the problem of antibiotic resistance because this is where most antibiotics are prescribed. Despite a number of evidence based interventions targeting the management of community infections, the inappropriate antibiotic prescribing rates remain high.

DISCUSSION

The question is how can appropriate prescribing of antibiotics through the use of Antimicrobial Stewardship (AMS) programs be successfully implemented in primary care. We discuss that a top-down approach utilising a combination of strategies to ensure the sustainable implementation and uptake of AMS interventions in the community is necessary to support clinicians and ensure a robust implementation of AMS in primary care. Specifically, we recommend a national accreditation standard linked to the framework of Core Elements of Outpatient Antibiotic Stewardship, supported by resources to fund the implementation of AMS interventions that are connected to quality improvement initiatives. This article debates how this can be achieved. The paper highlights that in order to support the sustainable uptake of AMS programs in primary care, an approach similar to the hospital and post-acute care settings needs to be adopted, utilising a combination of behavioural and regulatory processes supported by sustainable funding. Without these strategies the problem of inappropriate antibiotic prescribing will not be adequately addressed in the community and the successful implementation and uptake of AMS programs will remain a dream.

Successful improvement of antibiotic prescribing at Primary Care in Andalusia following the implementation of an antimicrobial guide through multifaceted interventions: An interrupted time-series analysis

BACKGROUND

Most effective strategies designed to improve antimicrobial prescribing have multiple approaches. We assessed the impact of the implementation of a rigorous antimicrobial guide and subsequent multifaceted interventions aimed at improving antimicrobial use in Primary Care.

METHODS

A quasi-experimental study was designed. Interventions aimed at achieving a good implementation of the guide consisted of the development of electronic decision support tools, local training meetings, regional workshops, conferences, targets for rates of antibiotic prescribing linked to financial incentives, feedback on antibiotic prescribing, and the implementation of a structured educational antimicrobial stewardship program. Interventions started in 2011, and continued until 2018. Outcomes: rates of antibiotics use, calculated into defined daily doses per 1,000 inhabitants-day (DID). An interrupted time-series analysis was conducted. The study ran from January 2004 until December 2018.

RESULTS

Overall annual antibiotic prescribing rates showed increasing trends in the pre-intervention period. Interventions were followed by significant changes on trends with a decline over time in antibiotic prescribing. Overall antibiotic rates dropped by 28% in the Aljarafe Area and 22% in Andalusia between 2011 and 2018, at rates of -0.90 DID per year (95%CI:-1.05 to -0.75) in Aljarafe, and -0.78 DID (95%CI:-0.95 to -0.60) in Andalusia. Reductions occurred at the expense of the strong decline of penicillins use (33% in Aljarafe, 25% in Andalusia), and more precisely, amoxicillin clavulanate, whose prescription plummeted by around 50%. Quinolones rates decreased before interventions, and continued to decline following interventions with more pronounced downward trends. Decreasing cephalosporins trends continued to decline, at a lesser extent, following interventions in Andalusia. Trends of macrolides rates went from a downward trend to an upward trend from 2011 to 2018.

CONCLUSIONS

Multifaceted interventions following the delivering of a rigorous antimicrobial guide, maintained in long-term, with strong institutional support, could led to sustained reductions in antibiotic prescribing in Primary Care.

Impact of antimicrobial stewardship fee on prescribing for Japanese pediatric patients with upper respiratory infections

BACKGROUND

In 2018, the Japanese medical reimbursement system was revised to introduce a fee for the implementation of an antimicrobial stewardship (AS) fee for pediatric patients. The purpose of this study was to evaluate physicians' prescription behavior following this revision.

METHODS

We conducted a retrospective observational study from January 1, 2017 to September 30, 2018 of pediatric (< 15 years) outpatients with upper respiratory tract infections (URIs). To assess the pattern of antibiotic prescription for the treatment of pediatric URIs before and after the introduction of the AS fee, we extracted data on pediatric URIs, diagnosed during the study period. Patients were divided based on whether medical facilities claimed AS fees. We defined antibiotic use as the number of antibiotics prescribed, and evaluated the proportion of each class to the total number of antibiotics prescribed. We also recorded the number of medical facilities that each patient visited during the study period.

RESULTS

The frequency of antibiotic prescription decreased after AS fee implementation, regardless of whether the facility claimed the AS fee, but tended to be lower in facilities that claimed the fee. Additionally, the frequency of antibiotic prescription decreased in all age groups. Despite the reduced frequency of antibiotic prescription, consultation behavior did not change.

CONCLUSIONS

The AS fee system, which compensates physicians for limiting antibiotic prescriptions, helped to reduce unnecessary antibiotic prescription and is thus a potentially effective measure against antimicrobial resistance.

Patient expectation trends on receiving antibiotic prescriptions for respiratory tract infections: A systematic review and meta-regression analysis

BACKGROUND

Despite a variety of programs developed to control inappropriate antibiotic prescribing for viral infections, antibiotics are still prescribed excessively for Respiratory Tract Infections (RTI). The patient's expectation to receive an antibiotic often influences the clinician's decision and can lead to inappropriate antibiotic prescriptions. Our objective was to investigate the changes in patient expectations over time when presenting with symptoms of a respiratory infection.

METHODS

We performed a systematic review of patient's expectation to receive antibiotics for RTIs. Two reviewers independently evaluated the collected studies based on inclusion and exclusion criteria. Our search initially identified 12 070 studies, of which 321 studies were eligible for full text review and 37 articles were selected for final evaluation. Meta-regression analysis was used to evaluate the association between patient expectations and different years. Heterogeneity was evaluated using the Q statistic.

RESULTS

Patient expectations (effect size) were pooled using a random effects model. The effect-equality test showed heterogeneity among studies (Q = 3304.23, df = 40, P < 0.0001, k = 40, τ²  = 0.63). Meta-regression results revealed that there is a significant linear negative relationship (B = -1.8374, P < 0.05) between patient expectation and year of data collection, at the global level. A similar finding is observed for the subset of studies conducted outside United States (U.S.) (B = -1.2411, P < 0.1). However, there is no discernible trend for patient expectation in the U.S. or among children and adult subgroups. Also, no significant differences are observed between the patient expectations when considering different age groups.

CONCLUSION

The trend of patient expectation for receiving antibiotics for RTIs is declining over time on a global level and also outside the U.S.

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.

Quantifying Antimicrobial Use in Dutch Companion Animals

Antimicrobial resistance (AMR) is an increasing threat, both in human and in veterinary medicine. To reduce the selection and spread of AMR, antimicrobial use (AMU) should be optimized, also in companion animals. To be able to optimize AMU, a feasible method to quantify AMU and information on current AMU are needed. Therefore, a method to quantify AMU was developed, using the number of Defined Daily Doses Animal (DDDA). This method was used to explore applied antimicrobial classes and to identify differences in prescribing patterns in time and between veterinary clinics. Antimicrobial procurement data of the years 2012-2014 were collected retrospectively from 100 Dutch veterinary clinics providing care for companion animals. The mean number of DDDAs per clinic per year decreased significantly from 2012 to 2014. A shift in used classes of antimicrobials (AMs) was seen as well, with a significant decrease in use of third choice AMs (i.e., fluoroquinolones and third generation cephalosporins). Large differences in total AMU were seen between clinics ranging from 64-fold in 2012 to 20-fold in 2014. Despite the relative low and decreasing AMU in Dutch companion animal clinics during the study, the substantial differences in antimicrobial prescribing practices between clinics suggest that there is still room for quantitative and qualitative optimization of AMU.

Effectiveness and safety of electronically delivered prescribing feedback and decision support on antibiotic use for respiratory illness in primary care: REDUCE cluster randomised trial

OBJECTIVES

To evaluate the effectiveness and safety at population scale of electronically delivered prescribing feedback and decision support interventions at reducing antibiotic prescribing for self limiting respiratory tract infections.

DESIGN

Open label, two arm, cluster randomised controlled trial.

SETTING

UK general practices in the Clinical Practice Research Datalink, randomised between 11 November 2015 and 9 August 2016, with final follow-up on 9 August 2017.

PARTICIPANTS

79 general practices (582 675 patient years) randomised (1:1) to antimicrobial stewardship (AMS) intervention or usual care.

INTERVENTIONS

AMS intervention comprised a brief training webinar, automated monthly feedback reports of antibiotic prescribing, and electronic decision support tools to inform appropriate prescribing over 12 months. Intervention components were delivered electronically, supported by a local practice champion nominated for the trial.

MAIN OUTCOME MEASURES

Primary outcome was the rate of antibiotic prescriptions for respiratory tract infections from electronic health records. Serious bacterial complications were evaluated for safety. Analysis was by Poisson regression with general practice as a random effect, adjusting for covariates. Prespecified subgroup analyses by age group were reported.

RESULTS

The trial included 41 AMS practices (323 155 patient years) and 38 usual care practices (259 520 patient years). Unadjusted and adjusted rate ratios for antibiotic prescribing were 0.89 (95% confidence interval 0.68 to 1.16) and 0.88 (0.78 to 0.99, P=0.04), respectively, with prescribing rates of 98.7 per 1000 patient years for AMS (31 907 prescriptions) and 107.6 per 1000 patient years for usual care (27 923 prescriptions). Antibiotic prescribing was reduced most in adults aged 15-84 years (adjusted rate ratio 0.84, 95% confidence interval 0.75 to 0.95), with one antibiotic prescription per year avoided for every 62 patients (95% confidence interval 40 to 200). There was no evidence of effect for children younger than 15 years (adjusted rate ratio 0.96, 95% confidence interval 0.82 to 1.12) or people aged 85 years and older (0.97, 0.79 to 1.18); there was also no evidence of an increase in serious bacterial complications (0.92, 0.74 to 1.13).

CONCLUSIONS

Electronically delivered interventions, integrated into practice workflow, result in moderate reductions of antibiotic prescribing for respiratory tract infections in adults, which are likely to be of importance for public health. Antibiotic prescribing to very young or old patients requires further evaluation.

Drivers of Irrational Use of Antibiotics in Europe

The unnecessary use of antibiotics and concomitant rapid growth of antibiotic resistance (ABR) is a widely acknowledged threat to global health, development, and sustainability. While the underlying cause of ABR is undoubtedly the overall volume of antibiotic use in general, irrational antibiotic use, which is influenced by several interrelated factors, is a major contributory factor. Here, we aimed to present and describe selected main drivers of irrational use of antibiotics in Europe. We performed a broad search of the current literature in databases such as PubMed, Google Scholar, Cochrane, as well as various institutional websites (World Health Organization, European Observatory, European Commission) to provide a new perspective on selected drivers of irrational antibiotic use in Europe. We also searched for relevant literature using snowballing, i.e., using reference lists of papers to identify additional papers. In this narrative review, we present that major factors among the general public driving antibiotic resistance are lack of public knowledge and awareness, access to antibiotics without prescription and leftover antibiotics, and knowledge attitude and perception of prescribers and dispensers, inadequate medical training, pharmaceutical promotion, lack of rapid and sufficient diagnostic tests, and patient⁻doctor interaction as major factors among healthcare providers. We further discuss initiatives that, if taken and implemented, can have an impact on and improve the current situation in Europe.

Quality assessment in general practice: diagnosis and antibiotic treatment of acute respiratory tract infections

OBJECTIVE

To investigate areas in need of quality improvement within the diagnostic process and antibiotic treatment of acute respiratory tract infections (RTIs) in Danish general practice by using quality indicators (QIs).

DESIGN AND SETTING

During a 4-week period in winter 2017, a prospective registration of patients diagnosed with RTIs was conducted in general practice in two regions of Denmark.

SUBJECTS

Throughout the registration period each patient with symptoms of an RTI was registered. Information about age, symptoms and findings, duration of symptoms, the use and result of clinical tests, allergy towards penicillin, referral to secondary care and the antibiotic given were recorded.

MAIN OUTCOME MEASURES

Values and acceptable ranges for QIs focusing on the diagnostic process, the decision to prescribe antibiotics and the choice of antibiotics for patients with RTIs.

RESULTS

Regarding the diagnostic process nearly all QIs for patients diagnosed with acute pharyngotonsillitis and pneumonia fell within the acceptable range. Contrarily, the diagnostic QIs for patients with acute otitis media and acute rhinosinusitis were outside the acceptable range. All indicators designed to measure overuse of antibiotics were outside the acceptable range and nearly all indicators assessing if patients were sufficiently treated fell within the acceptable range. QIs assessing use of the recommended type of antibiotic were only within the acceptable range for patients diagnosed with acute pharyngotonsillitis.

CONCLUSION

The findings indicate an overuse of antibiotics for RTIs in Danish general practice. Especially management of acute rhinosinusitis and acute bronchitis should be targeted in future quality improvement projects.

KEY POINTS

To improve antibiotic prescribing in general practice it is important to focus on both the diagnostic process and the prescribing patterns. The findings indicate an overuse of antibiotics for acute respiratory tract infections in Danish general practice. Especially the diagnostic process and antibiotic prescribing patterns for acute rhinosinusitis and acute bronchitis could benefit from future quality improvement interventions.

From paper to practice: Strategies for improving antibiotic stewardship in the pediatric ambulatory setting

Antibiotic stewardship aims to better patient outcomes, reduce antibiotic resistance, and decrease unnecessary health care costs by improving appropriate antibiotic use. More than half of annual antibiotic expenditures for antibiotics in the United States are prescribed in the ambulatory setting. This review provides a summary of evidence based strategies shown to improve antibiotic prescribing in ambulatory care settings including: providing education to patients and their families, providing education to clinicians regarding best practices for specific conditions, providing communications training to clinicians, implementing disease-specific treatment algorithms, implementing delayed prescribing for acute otitis media, supplying prescribing feedback to providers with peer comparisons, using commitment letters, and prompting providers to justify antibiotic prescribing for diagnoses for which antibiotics are not typically recommended. These various mechanisms to improve stewardship can be tailored to a specific practice's work flow and culture. Interventions should be used in combination to maximize impact. The intent with this review is to provide an overview of strategies that pediatric providers can take from paper to practice.

Observational pre-post study showed that a quality improvement project reduced paediatric antibiotic prescribing rates in primary care

AIM

This study assessed the effectiveness of a quality improvement project that aimed to promote more considered antibiotic prescribing in paediatric primary care.

METHOD

This was an observational pre-post study that used patient-level prescribing data from the Emilia-Romagna region of Italy to monitor indicators from 2005 to 2016. Multilevel interventions and activities were started in 2007 and these included developing guidelines and updates, disseminating evidence, audits and feedback, public information campaigns, engaging health managers and performance incentives. The primary outcomes were total antibiotic prescription rates for children aged 0-13 years and the rates for specific drugs.

RESULTS

The intervention was associated with a significant reduction in the antibiotic prescribing rate, from 1307 per 1000 children in 2005 to 881 prescriptions in 2016 (p for trend <0.001), and a significant increase in the ratio of amoxicillin to amoxicillin-clavulanic acid, from 0.6 to 1.1 (p for trend = 0.001). Prescriptions of other second-choice antibiotics also declined significantly. In contrast, antibiotic prescribing rates remained high in the rest of Italy.

CONCLUSION

The intervention was effective in promoting a more considered use of antibiotic in paediatric primary care in an Italian region. Further studies are needed to confirm its effectiveness in other settings.

Improving antibiotic prescribing by general practitioners: a protocol for a systematic review of interventions involving pharmacists

INTRODUCTION

Effective antibiotic options in general practice for patients with infections are declining significantly due to antibiotic over-prescribing and emerging antibiotic resistance. To better improve antibiotic prescribing by general practitioner (GP), pharmacist-GP collaborations have been promoted under antibiotic stewardship programmes. However, there is insufficient information about whether and how pharmacists help GPs to more appropriately prescribe antibiotics. This systematic review aims to determine whether pharmacist-led or pharmacist-involved interventions are effective at improving antibiotic prescribing by GPs.

METHODS AND ANALYSIS

A systematic review of English language randomised controlled trials (RCTs), cluster RCTs, controlled before-and-after studies and interrupted time series studies cited in MEDLINE, EMBASE, EMCARE, CINAHL Plus, PubMed, PsycINFO, Cochrane Central Register of Controlled Trials and Web of Science databases will be conducted. Studies will be included if a pharmacist is involved as the intervention provider and GPs are the intervention recipients in general practice setting. Data extraction and management will be conducted using Effective Practice and Organisation of Care data abstraction tools and a template for intervention description and replication. The Cochrane and ROBINS-I risk of bias assessment tools will be used to assess the methodological quality of studies. Primary outcome measures include changes (overall, broad spectrum and guidelines concordance) of GP-prescribed antibiotics. Secondary outcomes include quality of antibiotic prescribing, delayed antibiotic use, acceptability and feasibility of interventions. Meta-analysis for combined effect and forest plots, χ2 test and I2 statistics for detailed heterogeneity and sensitivity analysis will be performed if data permit. Grading of Recommendations Assessment, Development and Evaluation and Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols guidance will be used to report findings.

ETHICS AND DISSEMINATION

No ethics approval is required as no primary, personal or confidential data are being collected in this study. The findings will be disseminated to national and international scientific sessions and published in a peer-reviewed journal.

Identifying practice-related factors for high-volume prescribers of antibiotics in Danish general practice

Objectives

In Denmark, general practice is responsible for 75% of antibiotic prescribing in the primary care sector. We aimed to identify practice-related factors associated with high prescribers, including prescribers of critically important antibiotics as defined by WHO, after accounting for case mix by practice.

Methods

We performed a nationwide register-based survey of antibiotic prescribing in Danish general practice from 2012 to 2013. The unit of analysis was the individual practice. We used multivariable regression analyses and an assessment of relative importance to identify practice-related factors driving high antibiotic prescribing rates.

Results

We included 98% of general practices in Denmark ( n  =   1962) and identified a 10% group of high prescribers who accounted for 15% of total antibiotic prescriptions and 18% of critically important antibiotic prescriptions. Once case mix had been accounted for, the following practice-related factors were associated with being a high prescriber: lack of access to diagnostic tests in practice (C-reactive protein and urine culture); high use of diagnostic tests (urine culture and strep A throat test); a low percentage of antibiotic prescriptions issued over the phone compared with all antibiotic prescriptions; and a high number of consultations per 1000 patients. We also found that a low number of consultations per 1000 patients was associated with a reduced likelihood of being a high prescriber of antibiotics.

Conclusions

An apparent underuse or overuse of diagnostic tests in general practice as well as organizational factors were associated with high-prescribing practices. Furthermore, the choice of antibiotic type seemed less rational among high prescribers.

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.

Development of an intervention to reduce antibiotic use for childhood coughs in UK primary care using critical synthesis of multi-method research

Background

Overuse of antibiotics contributes to the global threat of antimicrobial resistance. Antibiotic stewardship interventions address this threat by reducing the use of antibiotics in occasions or doses unlikely to be effective. We aimed to develop an evidence-based, theory-informed, intervention to reduce antibiotic prescriptions in primary care for childhood respiratory tract infections (RTI). This paper describes our methods for doing so.

Methods

Green and Krueter’s Precede/Proceed logic model was used as a framework to integrate findings from a programme of research including 5 systematic reviews, 3 qualitative studies, and 1 cohort study. The model was populated using a strength of evidence approach, and developed with input from stakeholders including clinicians and parents.

Results

The synthesis produced a series of evidence-based statements summarizing the quantitative and qualitative evidence for intervention elements most likely to result in changes in clinician behaviour. Current evidence suggests that interventions which reduce clinical uncertainty, reduce clinician/parent miscommunication, elicit parent concerns, make clear delayed or no-antibiotic recommendations, and provide clinicians with alternate treatment actions have the best chance of success. We designed a web-based within-consultation intervention to reduce clinician uncertainty and pressure to prescribe, designed to be used when children with RTI present to a prescribing clinician in primary care.

Conclusions

We provide a worked example of methods for the development of future complex interventions in primary care, where multiple factors act on multiple actors within a complex system. Our synthesis provided intervention guidance, recommendations for practice, and highlighted evidence gaps, but questions remain about how best to implement these recommendations. The funding structure which enabled a single team of researchers to work on a multi-method programme of related studies (NIHR Programme Grant scheme) was key in our success.

Trial registration

The feasibility study accompanying this intervention was prospectively registered with the ISRCTN registry (ISRCTN23547970), on 27 June 2014.

Community pharmacists-Leaders for antibiotic stewardship in respiratory tract infection

WHAT IS KNOWN AND OBJECTIVE

Hospital-based pharmacists are established antibiotic stewards, but the potential for community pharmacists is largely untapped. This commentary explores the potential leadership role of the community pharmacist in antibiotic stewardship using upper respiratory tract infection (URTI) as an example.

COMMENT

Community pharmacists are well placed for antibiotic stewardship, possessing the capability (knowledge of medicines), opportunity (contact with prescribers and patients) and inherent commitment. Providing further motivation with information on patient education has great potential to change patient behaviour with respect to consulting a healthcare professional for an antibiotic prescription. A Global Respiratory Infection Partnership pharmacy-led educational initiative was shown to have a positive impact and can promote appropriate self-management of URTI and reduce levels of inappropriate antibiotic use.

WHAT IS NEW AND CONCLUSION

Community pharmacists are ideally placed as antibiotic stewards to lead the quest to contain the threat of antibiotic resistance.
