What is the role of quality circles in strategies to optimise antibiotic prescribing? A pragmatic cluster-randomised controlled trial in primary care

Differences in antibiotic prescribing quality in Belgian out-of-hours primary care services

OBJECTIVES

This study aims to compare trends in antibiotic prescribing behaviour for lower urinary tract infections among different out-of-hours primary care services.

METHODS

Cross-sectional study using routine prescription data extracted from electronic health records from six out-of-hours services. The study population included 5888 cases diagnosed with an uncomplicated lower urinary tract infection from 2016 to 2020. Prescriptions were assessed based on the national guidelines.

RESULTS

Considering the total study period, an antibiotic was prescribed in 98.9% of cases. Among these cases, 55.0% was prescribed a guideline recommended antibiotic, 21.0% was prescribed fosfomycin, 17.4% was prescribed a quinolone and 1.8% was prescribed more than one antibiotic. Guideline recommended prescribing improved substantially over time. However, there were significant differences among out-of-hours services in terms of proportion over the total study period (between 49.0% and 66.7%) as well as in terms of time-trend pattern.

CONCLUSION

Substantial differences among out-of-hours services suggest a potential for further improvement in the quality of antibiotic prescribing. Monitoring prescribing behaviour per out-of-hours primary care service can guide focused interventions.

Implementation fidelity in a multifaceted program to foster rational antibiotics use in primary care: an observational study

BACKGROUND

The ARena study (Sustainable Reduction of Antimicrobial Resistance in German Ambulatory Care) is a three-arm, cluster randomized trial to evaluate a multifaceted implementation program in a German primary care setting. In the context of a prospective process evaluation conducted alongside ARena, this study aimed to document and explore fidelity of the implementation program.

METHODS

This observational study is based on data generated in a three-wave survey of 312 participating physicians in the ARena program and attendance documentation. Measures concerned persistence of participation in the ARena program and adherence to intervention components (thematic quality circles, e-learning, basic expenditure reimbursements, additional bonus payments and a computerized decision support system). Participants' views on five domains of the implementation were also measured. Binary logistic and multiple linear regression analyses were used to explore which views on the implementation were associated with participants' adherence to quality circles and use of additional bonus compensation.

RESULTS

The analysis of fidelity showed overall high persistence of participation in the intervention components across the three intervention arms (90,1%; 97,9%; 92,9%). 96.4% of planned quality circles were delivered to study participants and, across waves, 30.4% to 93% of practices participated; 56.1% of physicians attended the maximum of four quality circles. 84% of the practices (n = 158) with a minimum of one index patient received a performance-based additional bonus payment at least once. In total, bonus compensation was triggered for 51.8% of affected patients. Participation rate for e-learning (a prerequisite for reimbursement of project-related expenditure) covered 90.8% of practices across all intervention arms, with the highest rate in arm II (96.5%). Uptake of expenditure reimbursement was heterogeneous across study arms, with a mean rate of 86.5% (89.1% in arm I, 96.4% in arm II and 74.1% in arm III). Participants' views regarding participant responsiveness (OR = 2.298) 95% CI [1.598, 3.305] and Context (OR = 2.146) 95% CI [1.135, 4.055] affected additional bonus payment. Participants' views on participant responsiveness (Beta = 0.718) 95% CI [0.479, 0.957], Context (Beta = 0.323) 95% CI [0.055, 0.590] and Culture of shared decision-making (Beta = -0.334) 95% CI [-0.614, -0.053] affected quality circle attendance.

CONCLUSION

This study showed an overall high fidelity to the implementation program. Participants' views on the implementation were associated with degree of intervention fidelity.

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

Background

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

Objectives

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

Design

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

Data sources

The Clinical Practice Research Datalink.

Setting

This took place in UK general practices.

Participants

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

Main outcome measures

Sepsis and localised bacterial infections.

Results

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

Limitations

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

Conclusions

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

Future work

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

Effectiveness of interventions involving pharmacists on antibiotic prescribing by general practitioners: a systematic review and meta-analysis

BACKGROUND

The use of community antibiotic stewardship programmes (ASPs) is rising; however, their effectiveness when pharmacists are involved is uncertain.

OBJECTIVES

To assess the effectiveness of ASPs involving pharmacists at improving antibiotic prescribing by general practitioners (GPs).

METHODS

Medline, Embase, Emcare, PubMed, PsycINFO, Cochrane CENTRAL, CINAHL Plus and Web of Science databases were searched to February 2018. Randomized and non-randomized studies of ASPs involving pharmacists as interventionists to GPs were included. Primary outcomes were absolute changes in GPs' antibiotic prescribing rate (APR) and antibiotic prescribing adherence rate (APAR) according to recommendations/guidelines. Meta-analysis used random effects models.

RESULTS

Fifteen studies reporting 18 trials were included in the meta-analysis: 8 assessed the APR and 10 the APAR. APR reductions (OR 0.86, 95% CI 0.78-0.95, moderate-certainty evidence) and APAR improvements (OR 1.96, 95% CI 1.56-2.45, high-certainty evidence) were observed at 6 months median intervention follow-up. High-quality randomized trials reduced the APR (OR 0.92, 95% CI 0.90-0.94) and increased the APAR (OR 2.55, 95% CI 2.16-3.01). Interventions were successful in decreasing the APR (OR 0.93, 95% CI 0.90-0.95) and increasing the APAR (OR 1.72, 95% CI 1.04-2.84) when implemented by a pharmacist-GP team. Interventions involving pharmacist-infectious disease professional teams also decreased the APR (OR 0.81, 95% CI 0.66-1.0) and increased the APAR (OR 2.36, 95% CI 1.87-2.96). GP education plus prescribing feedback, and group meetings were effective in both outcomes, whereas GP education, academic detailing and workshop training were effective in APAR outcome. However, substantial heterogeneity was demonstrated.

CONCLUSIONS

ASPs involving pharmacists are effective in decreasing antibiotic prescribing and increasing guideline-adherent antibiotic prescribing by GPs.

Revisiting patient expectations and experiences of antibiotics in an era of antimicrobial resistance: Qualitative study

OBJECTIVE

To investigate contemporary patient expectations and experiences of antibiotic prescribing in England.

BACKGROUND

Primary care providers' compliance with patient influences has been identified as a motivation for antibiotic-prescribing behaviour. Since 2013, there have been concerted efforts to publicize and address the growing threat of antimicrobial resistance. A fresh qualitative insight into patient expectations and experiences is needed.

DESIGN

Qualitative study using semi-structured interviews.

SETTING AND PARTICIPANTS

Two English regions, one an urban metropolitan area and the other a town in rural England. Patients who recently consulted for infections were recruited. The information power approach was used to determine the number of participants, yielding a sample of 31 participants.

MAIN MEASURES

Thematic analysis was carried out to analyse the interview data.

RESULTS

Five themes were identified: beliefs, expectations, experiences of taking antibiotic, experience of antimicrobial resistance and side-effects, and experiences of consultations. The accounts reflected improved public knowledge: antibiotics were perceived to be much-needed medicines that should be prescribed when appropriate. The data showed that patients formed expectations of expectations, trying to read the prescribers' intentions and reflect on the dependency between what prescribers and patients wanted. Patient experiences featured as nuanced and detailed with knowledge of AMR and side-effects of antibiotics in the context of positive consultation experiences.

CONCLUSIONS

The study highlighted complex interplays between adherence to antibiotics and consuming antibiotics in reflexive, informed ways. Ensuring that present and future patients are informed about potential benefits and harms of antibiotic use will contribute to future antimicrobial stewardship.

The role of education in antimicrobial stewardship

The role of antimicrobial stewardship programmes (ASPs) has expanded in health systems. ASP interventions often contain an educational component; however, current guidelines suggest that educational interventions should not be used alone but to support other stewardship interventions. Such interventions are most commonly directed towards prescribers (often general practice physicians) with few studies offering education towards other healthcare providers such as pharmacists, nurses, or even members of the stewardship team. Educational interventions are offered most frequently, but not exclusively, with concomitant stewardship interventions such as prospective audit and feedback. Such strategies appear to positively impact prescribing behaviours, but it is not possible to isolate the effect of education from other interventions. Common educational methods include one-time seminars and online e-learning modules, but unique strategies such as social media platforms, educational video games and problem-based learning modules have also been employed. Education directed towards patients often occurs in conjunction with education of local prescribers and wider community-based efforts to impact prescribing. Such studies evaluating patient education often include passive educational leaflets and focus most often on appropriate treatment of upper respiratory tract infections. Educational interventions appear to be an integral component of other interventions of ASPs; however, there is a paucity of evidence to support use as a stand-alone intervention outside of regional public health interventions. Future studies should focus on efficacy of educational interventions including providing education to non-prescribers and disease states beyond upper respiratory tract infections to demonstrate a broader role for education in ASP activities.

Use of quality circles for primary care providers in 24 European countries: an online survey of European Society for Quality and Safety in family practice delegates

Objective: To identify and describe the core characteristics and the spread of quality circles in primary healthcare in European countries. Design: An online survey was conducted among European Society for Quality and Safety in Family Practice (EQuiP) delegates. To allow comparison with earlier results, a similar survey as in a study from 2000 was used. Setting: Primary Health Care in European countries. Subjects: General practitioners, delegated experts of the European Society for Quality and Safety in Family Practice (EQuiP). Main outcome measures: (1) Attendance in quality circles (2) their objectives (3) methods of quality improvement quality circles use (4) facilitator's role and training (5) role of institutions (6) supporting material and data sources quality circles use. Results: 76% of the delegates responded, representing 24 of 25 countries. In 13 countries, more than 10% of general practitioners participated in quality circles, compared with eight countries in 2000. The focus of quality circles moved from continuous medical education to quality improvement. Currently, quality circles groups use case-based discussions, educational materials and local opinion leaders in addition to audit and feedback. Some national institutions provide training for facilitators and data support for quality circle groups. Conclusion: The use of quality circles has increased in European countries with a shift in focus from continuous medical education to quality improvement. Well-trained facilitators are important, as is the use of varying didactic methods and quality improvement tools. Qualitative inquiry is necessary to examine why QCs thrive or fail in different countries and systems. KEY POINTS Countries with already established quality circle movements increased their participation rate and extended their range of quality circle activities The focus of quality circles has moved from CME/CPD to quality improvement Well-trained facilitators are important, as is the use of varying didactic methods and quality improvement tools Institutions should provide supporting material and training for facilitators.

Tools developed and disseminated by guideline producers to promote the uptake of their guidelines

BACKGROUND

The uptake of clinical practice guidelines (CPGs) is inconsistent, despite their potential to improve the quality of health care and patient outcomes. Some guideline producers have addressed this problem by developing tools to encourage faster adoption of new guidelines. This review focuses on the effectiveness of tools developed and disseminated by guideline producers to improve the uptake of their CPGs.

OBJECTIVES

To evaluate the effectiveness of implementation tools developed and disseminated by guideline producers, which accompany or follow the publication of a CPG, to promote uptake. A secondary objective is to determine which approaches to guideline implementation are most effective.

SEARCH METHODS

We searched the Cochrane Effective Practice and Organisation of Care (EPOC) Group Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL); NHS Economic Evaluation Database, HTA Database; MEDLINE and MEDLINE In-Process and other non-indexed citations; Embase; PsycINFO; CINAHL; Dissertations and Theses, ProQuest; Index to Theses; Science Citation Index Expanded, ISI Web of Knowledge; Conference Proceedings Citation Index - Science, ISI Web of Knowledge; Health Management Information Consortium (HMIC), and NHS Evidence up to February 2016. We also searched trials registers, reference lists of included studies and relevant websites.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and cluster-RCTs, controlled before-and-after studies (CBAs) and interrupted time series (ITS) studies evaluating the effects of guideline implementation tools developed by recognised guideline producers to improve the uptake of their own guidelines. The guideline could target any clinical area.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed the risk of bias of each included study using the Cochrane 'Risk of bias' criteria. We graded our confidence in the evidence using the approach recommended by the GRADE working group. The clinical conditions targeted and the implementation tools used were too heterogenous to combine data for meta-analysis. We report the median absolute risk difference (ARD) and interquartile range (IQR) for the main outcome of adherence to guidelines.

MAIN RESULTS

We included four cluster-RCTs that were conducted in the Netherlands, France, the USA and Canada. These studies evaluated the effects of tools developed by national guideline producers to implement their CPGs. The implementation tools evaluated targeted healthcare professionals; none targeted healthcare organisations or patients.One study used two short educational workshops tailored to barriers. In three studies the intervention consisted of the provision of paper-based educational materials, order forms or reminders, or both. The clinical condition, type of healthcare professional, and behaviour targeted by the CPG varied across studies.Two of the four included studies reported data on healthcare professionals' adherence to guidelines. A guideline tool developed by the producers of a guideline probably leads to increased adherence to the guidelines; median ARD (IQR) was 0.135 (0.115 and 0.159 for the two studies respectively) at an average four-week follow-up (moderate certainty evidence), which indicates a median 13.5% greater adherence to guidelines in the intervention group. Providing healthcare professionals with a tool to improve implementation of a guideline may lead to little or no difference in costs to the health service.

AUTHORS' CONCLUSIONS

Implementation tools developed by recognised guideline producers probably lead to improved healthcare professionals' adherence to guidelines in the management of non-specific low back pain and ordering thyroid-function tests. There are limited data on the relative costs of implementing these interventions.There are no studies evaluating the effectiveness of interventions targeting the organisation of care (e.g. benchmarking tools, costing templates, etc.), or for mass media interventions. We could not draw any conclusions about our second objective, the comparative effectiveness of implementation tools, due to the small number of studies, the heterogeneity between interventions, and the clinical conditions that were targeted.

Changing the Antibiotic Prescribing of general practice registrars: the ChAP study protocol for a prospective controlled study of a multimodal educational intervention

Background

Australian General Practitioners (GPs) are generous prescribers of antibiotics, prompting concerns including increasing antimicrobial resistance in the community. Recent data show that GPs in vocational training have prescribing patterns comparable with the high prescribing rate of their established GP supervisors. Evidence-based guidelines consistently advise that antibiotics are not indicated for uncomplicated upper respiratory tract infections (URTI) and are rarely indicated for acute bronchitis. A number of interventions have been trialled to promote rational antibiotic prescribing by established GPs (with variable effectiveness), but the impact of such interventions in a training setting is unclear. We hypothesise that intervening while early-career GPs are still developing their practice patterns and prescribing habits will result in better adherence to evidence-based guidelines as manifested by lower antibiotic prescribing rates for URTIs and acute bronchitis.

Methods/design

The intervention consists of two online modules, a face-to-face workshop for GP trainees, a face-to-face workshop for their supervisors and encouragement for the trainee-supervisor dyad to include a case-based discussion of evidence-based antibiotic prescribing in their weekly one-on-one teaching meetings.

We will use a non-randomised, non-equivalent control group design to assess the impact on antibiotic prescribing for acute upper respiratory infections and acute bronchitis by GP trainees in vocational training.

Discussion

Early-career GPs who are still developing their clinical practice and prescribing habits are an underutilized target-group for interventions to curb the growth of antimicrobial resistance in the community. Interventions that are embedded into existing training programs or are linked to continuing professional development have potential to increase the impact of existing interventions at limited additional cost.

Antimicrobial stewardship in outpatient settings: a systematic review

OBJECTIVE

Evaluate the effect of outpatient antimicrobial stewardship programs on prescribing, patient, microbial outcomes, and costs.

DESIGN

Systematic review

METHODS

Search of MEDLINE (2000 through November 2013), Cochrane Library, and reference lists of relevant studies. We included English language studies with patient populations relevant to the United States (eg, infectious conditions, prescription services) evaluating stewardship programs in outpatient settings and reporting outcomes of interest. Data regarding study characteristics and outcomes were extracted and organized by intervention type.

RESULTS

We identified 50 studies eligible for inclusion, with most (29 of 50; 58%) reporting on respiratory tract infections, followed by multiple/unspecified infections (17 of 50; 34%). We found medium-strength evidence that stewardship programs incorporating communication skills training and laboratory testing are associated with reductions in antimicrobial use, and low-strength evidence that other stewardship interventions are associated with improved prescribing. Patient-centered outcomes, which were infrequently reported, were not adversely affected. Medication costs were generally lower with stewardship interventions, but overall program costs were rarely reported. No studies reported microbial outcomes, and data regarding outpatient settings other than primary care clinics are limited.

CONCLUSIONS

Low- to moderate-strength evidence suggests that antimicrobial stewardship programs in outpatient settings improve antimicrobial prescribing without adversely effecting patient outcomes. Effectiveness depends on program type. Most studies were not designed to measure patient or resistance outcomes. Data regarding sustainability and scalability of interventions are limited.

Tailored interventions to address determinants of practice

BACKGROUND

Tailored intervention strategies are frequently recommended among approaches to the implementation of improvement in health professional performance. Attempts to change the behaviour of health professionals may be impeded by a variety of different barriers, obstacles, or factors (which we collectively refer to as determinants of practice). Change may be more likely if implementation strategies are specifically chosen to address these determinants.

OBJECTIVES

To determine whether tailored intervention strategies are effective in improving professional practice and healthcare outcomes. We compared interventions tailored to address the identified determinants of practice with either no intervention or interventions not tailored to the determinants.

SEARCH METHODS

We conducted searches of The Cochrane Library, MEDLINE, EMBASE, PubMed, CINAHL, and the British Nursing Index to May 2014. We conducted a final search in December 2014 (in MEDLINE only) for more recently published trials. We conducted searches of the metaRegister of Controlled Trials (mRCT) in March 2013. We also handsearched two journals.

SELECTION CRITERIA

Cluster-randomised controlled trials (RCTs) of interventions tailored to address prospectively identified determinants of practice, which reported objectively measured professional practice or healthcare outcomes, and where at least one group received an intervention designed to address prospectively identified determinants of practice.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed quality and extracted data. We undertook qualitative and quantitative analyses, the quantitative analysis including two elements: we carried out 1) meta-regression analyses to compare interventions tailored to address identified determinants with either no interventions or an intervention(s) not tailored to the determinants, and 2) heterogeneity analyses to investigate sources of differences in the effectiveness of interventions. These included the effects of: risk of bias, use of a theory when developing the intervention, whether adjustment was made for local factors, and number of domains addressed with the determinants identified.

MAIN RESULTS

We added nine studies to this review to bring the total number of included studies to 32 comparing an intervention tailored to address identified determinants of practice to no intervention or an intervention(s) not tailored to the determinants. The outcome was implementation of recommended practice, e.g. clinical practice guideline recommendations. Fifteen studies provided enough data to be included in the quantitative analysis. The pooled odds ratio was 1.56 (95% confidence interval (CI) 1.27 to 1.93, P value < 0.001). The 17 studies not included in the meta-analysis had findings showing variable effectiveness consistent with the findings of the meta-regression.

AUTHORS' CONCLUSIONS

Despite the increase in the number of new studies identified, our overall finding is similar to that of the previous review. Tailored implementation can be effective, but the effect is variable and tends to be small to moderate. The number of studies remains small and more research is needed, including trials comparing tailored interventions to no or other interventions, but also studies to develop and investigate the components of tailoring (identification of the most important determinants, selecting interventions to address the determinants). Currently available studies have used different methods to identify determinants of practice and different approaches to selecting interventions to address the determinants. It is not yet clear how best to tailor interventions and therefore not clear what the effect of an optimally tailored intervention would be.

The challenge of transferring an implementation strategy from academia to the field: a process evaluation of local quality improvement collaboratives in Dutch primary care using the normalization process theory

RATIONALE, AIMS AND OBJECTIVES

A quality improvement strategy consisting of comparative feedback and peer review embedded in available local quality improvement collaboratives proved to be effective in changing the test-ordering behaviour of general practitioners. However, implementing this strategy was problematic. We aimed for large-scale implementation of an adapted strategy covering both test ordering and prescribing performance. Because we failed to achieve large-scale implementation, the aim of this study was to describe and analyse the challenges of the transferring process.

METHODS

In a qualitative study 19 regional health officers, pharmacists, laboratory specialists and general practitioners were interviewed within 6 months after the transfer period. The interviews were audiotaped, transcribed and independently coded by two of the authors. The codes were matched to the dimensions of the normalization process theory.

RESULTS

The general idea of the strategy was widely supported, but generating the feedback was more complex than expected and the need for external support after transfer of the strategy remained high because participants did not assume responsibility for the work and the distribution of resources that came with it.

CONCLUSION

Evidence on effectiveness, a national infrastructure for these collaboratives and a general positive attitude were not sufficient for normalization. Thinking about managing large databases, responsibility for tasks and distribution of resources should start as early as possible when planning complex quality improvement strategies. Merely exploring the barriers and facilitators experienced in a preceding trial is not sufficient. Although multifaceted implementation strategies to change professional behaviour are attractive, their inherent complexity is also a pitfall for large-scale implementation.

Effectiveness of physician-targeted interventions to improve antibiotic use for respiratory tract infections

BACKGROUND

Antibiotic use and concomitant resistance are increasing. Literature reviews do not unambiguously indicate which interventions are most effective in improving antibiotic prescribing practice.

AIM

To assess the effectiveness of physician-targeted interventions aiming to improve antibiotic prescribing for respiratory tract infections (RTIs) in primary care, and to identify intervention features mostly contributing to intervention success.

DESIGN AND SETTING

Analysis of a set of physician-targeted interventions in primary care.

METHOD

A literature search (1990-2009) for studies describing the effectiveness of interventions aiming to optimise antibiotic prescription for RTIs by primary care physicians. Intervention features were extracted and effectiveness sizes were calculated. Association between intervention features and intervention success was analysed in multivariate regression analysis.

RESULTS

This study included 58 studies, describing 87 interventions of which 60% significantly improved antibiotic prescribing; interventions aiming to decrease overall antibiotic prescription were more frequently effective than interventions aiming to increase first choice prescription. On average, antibiotic prescription was reduced by 11.6%, and first choice prescription increased by 9.6%. Multiple interventions containing at least 'educational material for the physician' were most often effective. No significant added value was found for interventions containing patient-directed elements. Communication skills training and near-patient testing sorted the largest intervention effects.

CONCLUSION

This review emphasises the importance of physician education in optimising antibiotic use. Further research should focus on how to provide physicians with the relevant knowledge and tools, and when to supplement education with additional intervention elements. Feasibility should be included in this process.

Enabling factors for antibiotic prescribing for upper respiratory tract infections: perspectives of Lithuanian and Russian general practitioners

INTRODUCTION

General practitioners (GPs) write about 80% of all antibiotic prescriptions, the greatest number of them for patients with respiratory tract infections. However, there is a lack of research targeting the influence of external factors on antibiotic prescribing by physicians. This study aimed to explore experiences of GPs in Lithuania and the Russian Federation with regard to antibiotic prescription for upper respiratory tract infections. By such means it might be possible to reveal external enabling factors that influence antibiotic prescribing in these countries.

METHOD

Five focus groups were performed with 22 GPs from Lithuania and 29 GPs from the Kaliningrad Region of the Russian Federation; then, thematic analysis of data was performed.

RESULTS

Six thematic categories were identified that are related to external forces enabling antibiotic prescription: the necessity for political leadership to encourage clinically grounded antibiotic use; over-the-counter sale of antibiotics; designation of antibiotics as reimbursable medications; supervision by external oversight institutions; lack of guidelines for the treatment of upper respiratory tract infections; and pharmaceutical company activities.

CONCLUSIONS

Comprehensive efforts to reduce the burden of non-clinically grounded antibiotic prescription should go beyond addressing factors at the physician-patient level and take into account important factors in the enabling environment as well.

Can we improve adherence to guidelines for the treatment of lower urinary tract infection? A simple, multifaceted intervention in out-of-hours services

OBJECTIVES

To improve antimicrobial prescribing behaviour of general practitioners in large-scale out-of-hours services for uncomplicated lower urinary tract infection (LUTI) in females aged 20-80 years, which is regarded as one of the most prevalent bacterial infections in primary care.

METHODS

A quasi-experimental design was used in two regional large-scale out-of-hours services. A simple, multifaceted intervention was offered in a 16 week period in one region (the intervention region). During the two washout periods, at 5 and 17 months, we observed diagnoses and prescriptions. The main outcome measure was the share of appropriate and inappropriate prescriptions.

RESULTS

The proportion of patients with LUTI ranged from 1.0% to 2.1%. The relative proportion of appropriate prescriptions in the intervention region increased from 26.9% to 69.4%, but decreased afterwards to 40.8%.

CONCLUSIONS

A simple, multifaceted intervention for treatment of LUTI during out-of-hours care may improve the quality of antimicrobial prescribing, although the improvement may not be sustained in the longer term.

Effectiveness of multifaceted educational programme to reduce antibiotic dispensing in primary care: practice based randomised controlled trial

OBJECTIVE

To evaluate the effectiveness and costs of a multifaceted flexible educational programme aimed at reducing antibiotic dispensing at the practice level in primary care.

DESIGN

Randomised controlled trial with general practices as the unit of randomisation and analysis. Clinicians and researchers were blinded to group allocation until after randomisation.

SETTING

68 general practices with about 480,000 patients in Wales, United Kingdom.

PARTICIPANTS

34 practices were randomised to receive the educational programme and 34 practices to be controls. 139 clinicians from the intervention practices and 124 from control practices had agreed to participate before randomisation. Practice level data covering all the clinicians in the 68 practices were analysed.

INTERVENTIONS

Intervention practices followed the Stemming the Tide of Antibiotic Resistance (STAR) educational programme, which included a practice based seminar reflecting on the practices' own dispensing and resistance data, online educational elements, and practising consulting skills in routine care. Control practices provided usual care.

MAIN OUTCOME MEASURES

Total numbers of oral antibiotic items dispensed for all causes per 1000 practice patients in the year after the intervention, adjusted for the previous year's dispensing. Secondary outcomes included reconsultations, admissions to hospital for selected causes, and costs.

RESULTS

The rate of oral antibiotic dispensing (items per 1000 registered patients) decreased by 14.1 in the intervention group but increased by 12.1 in the control group, a net difference of 26.1. After adjustment for baseline dispensing rate, this amounted to a 4.2% (95% confidence interval 0.6% to 7.7%) reduction in total oral antibiotic dispensing for the year in the intervention group relative to the control group (P=0.02). Reductions were found for all classes of antibiotics other than penicillinase-resistant penicillins but were largest and significant individually for phenoxymethylpenicillins (penicillin V) (7.3%, 0.4% to 13.7%) and macrolides (7.7%, 1.1% to 13.8%). There were no significant differences between intervention and control practices in the number of admissions to hospital or in reconsultations for a respiratory tract infection within seven days of an index consultation. The mean cost of the programme was £2923 (€3491, $4572) per practice (SD £1187). There was a 5.5% reduction in the cost of dispensed antibiotics in the intervention group compared with the control group (-0.4% to 11.4%), equivalent to a reduction of about £830 a year for an average intervention practice.

CONCLUSION

The STAR educational programme led to reductions in all cause oral antibiotic dispensing over the subsequent year with no significant change in admissions to hospital, reconsultations, or costs. Trial registration ISRCT No 63355948.

Resource use and costs of treating acute cough/lower respiratory tract infections in 13 European countries: results and challenges

The objectives of this study were to estimate the resource use and cost of treating acute cough/lower respiratory tract infection (acute cough/LRTI) in 13 European countries, to explore reasons for differences in cost and to document the challenges that researchers face when collecting information on cost alongside multinational studies. Data on resource use and cost were collected alongside an observational study in 14 primary care networks across 13 European countries and a mean cost was generated for each network. The results show that the mean cost (standard deviation) of treating acute cough/LRTI in Europe ranged from euro23.88 (34.67) in Balatonfüred (Hungary) to euro116.47 (34.29) in Jonkoping (Sweden). The observed differences in costs were statistically significant (P < 0.01). Major cost drivers include general practitioner visits and drug costs in all networks, whilst differences in health systems and regional factors could account for differences in cost between networks. The major barrier to conducting multinational cost studies are barriers associated with identifying cost information.

Can clinical governance deliver quality improvement in Australian general practice and primary care? A systematic review of the evidence

OBJECTIVES

To review the literature on different models of clinical governance and to explore their relevance to Australian primary health care, and their potential contributions on quality and safety.

DATA SOURCES

25 electronic databases, scanning reference lists of articles and consultation with experts in the field. We searched publications in English after 1999, but a search of the German language literature for a specific model type was also undertaken. The grey literature was explored through a hand search of the medical trade press and websites of relevant national and international clearing houses and professional or industry bodies. 11 software packages commonly used in Australian general practice were reviewed for any potential contribution to clinical governance.

STUDY SELECTION

19 high-quality studies that assessed outcomes were included.

DATA EXTRACTION

All abstracts were screened by one researcher, and 10% were screened by a second researcher to crosscheck screening quality. Studies were reviewed and coded by four reviewers, with all studies being rated using standard critical appraisal tools such as the Strengthening the Reporting of Observational Studies in Epidemiology checklist. Two researchers reviewed the Australian general practice software. Interviews were conducted with 16 informants representing service, regional primary health care, national and international perspectives.

DATA SYNTHESIS

Most evidence supports governance models which use targeted, peer-led feedback on the clinician's own practice. Strategies most used in clinical governance models were audit, performance against indicators, and peer-led reflection on evidence or performance.

CONCLUSIONS

The evidence base for clinical governance is fragmented, and focuses mainly on process rather than outcomes. Few publications address models that enhance safety, efficiency, sustainability and the economics of primary health care. Locally relevant clinical indicators, the use of computerised medical record systems, regional primary health care organisations that have the capacity to support the uptake of clinical governance at the practice level, and learning from the Aboriginal community-controlled sector will help integrate clinical governance into primary care.

Establishing a standardized quality management system for the European Health Network GA2LEN

BACKGROUND

Quality management is increasingly important in clinical practice. The Global Allergy and Asthma European Network (GA(2)LEN) is a network of clinical and scientific excellence with originally 25 allergy centres in 16 European countries, a scientific society (European Academy of Allergology and Clinical Immunology), and a patient organization (European Federation of Allergy and Airways Diseases Patients' Associations). Although some allergy centres adhere to internal quality criteria, the implementation of a standardized quality management system for allergy centres across Europe was lacking.

OBJECTIVES

To implement standardized quality criteria among allergy centres organized within GA(2)LEN and thus ensure equal standards of diagnosis and care as well as to establish a culture of continuous quality improvement.

METHODS

Quality criteria covering, e.g., diagnostic and therapeutic procedures, and emergency preparedness to assure patient safety were developed and agreed upon by all 25 participating centres. To assure implementation of quality criteria, centres were audited to check quality indicators and document deviations. A follow-up survey was used to assess the usefulness of the project.

RESULTS

Deviations were documented mainly in the areas of emergency care/patient safety (27.3% lacked regular emergency training of doctors and nurses; 22.7% inadequate emergency intervention equipment; 22.7% lacked critical incidence reporting/root cause analyses) and handling of extracts/pharmaceuticals (31.8% lacked temperature logs of fridges; 4.5% inadequate check of expiration dates). Quality improvement was initiated as shown by findings of re-audits. Usefulness of the project was rated high.

CONCLUSION

The establishment of a quality management system with joint standards of care and harmonized procedures can be achieved in an international health network and ensures quality of care.

Tailored interventions to overcome identified barriers to change: effects on professional practice and health care outcomes

BACKGROUND

In the previous version of this review, the effectiveness of interventions tailored to barriers to change was found to be uncertain.

OBJECTIVES

To assess the effectiveness of interventions tailored to address identified barriers to change on professional practice or patient outcomes.

SEARCH STRATEGY

For this update, in addition to the EPOC Register and pending files, we searched the following databases without language restrictions, from inception until August 2007: MEDLINE, EMBASE, CINAHL, BNI and HMIC. We searched the National Research Register to November 2007. We undertook further searches to October 2009 to identify potentially eligible published or ongoing trials.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of interventions tailored to address prospectively identified barriers to change that reported objectively measured professional practice or healthcare outcomes in which at least one group received an intervention designed to address prospectively identified barriers to change.

DATA COLLECTION AND ANALYSIS

Two reviewers independently assessed quality and extracted data. We undertook quantitative and qualitative analyses. The quantitative analyses had two elements.1. We carried out a meta-regression to compare interventions tailored to address identified barriers to change with either no interventions or an intervention(s) not tailored to the barriers.2. We carried out heterogeneity analyses to investigate sources of differences in the effectiveness of interventions. These included the effects of: risk of bias, concealment of allocation, rigour of barrier analysis, use of theory, complexity of interventions, and the reported presence of administrative constraints.

MAIN RESULTS

We included 26 studies comparing an intervention tailored to address identified barriers to change to no intervention or an intervention(s) not tailored to the barriers. The effect sizes of these studies varied both across and within studies.Twelve studies provided enough data to be included in the quantitative analysis. A meta-regression model was fitted adjusting for baseline odds by fitting it as a covariate, to obtain the pooled odds ratio of 1.54 (95% CI, 1.16 to 2.01) from Bayesian analysis and 1.52 (95% CI, 1.27 to 1.82, P < 0.001) from classical analysis. The heterogeneity analyses found that no study attributes investigated were significantly associated with effectiveness of the interventions.

AUTHORS' CONCLUSIONS

Interventions tailored to prospectively identified barriers are more likely to improve professional practice than no intervention or dissemination of guidelines. However, the methods used to identify barriers and tailor interventions to address them need further development. Research is required to determine the effectiveness of tailored interventions in comparison with other interventions.

Stemming the Tide of Antibiotic Resistance (STAR): a protocol for a trial of a complex intervention addressing the 'why' and 'how' of appropriate antibiotic prescribing in general practice

BACKGROUND

After some years of a downward trend, antibiotic prescribing rates in the community have tended to level out in many countries. There is also wide variation in antibiotic prescribing between general practices, and between countries. There are still considerable further gains that could be made in reducing inappropriate antibiotic prescribing, but complex interventions are required. Studies to date have generally evaluated the effect of interventions on antibiotic prescribing in a single consultation and pragmatic evaluations that assess maintenance of new skills are rare. This paper describes the protocol for a pragmatic, randomized evaluation of a complex intervention aimed at reducing antibiotic prescribing by primary care clinicians.

METHODS AND DESIGN

We developed a Social Learning Theory based, blended learning program (on-line learning, a practice based seminar, and context bound learning) called the STAR Educational Program. The 'why of change' is addressed by providing clinicians in general practice with information on antibiotic resistance in urine samples submitted by their practice and their antibiotic prescribing data, and facilitating a practice-based seminar on the implications of this data. The 'how of change' is addressed through context-bound communication skills training and information on antibiotic indication and choice. This intervention will be evaluated in a trial involving 60 general practices, with general practice as the unit of randomization (clinicians from each practice to either receive the STAR Educational Program or not) and analysis. The primary outcome will be the number of antibiotic items dispensed over one year. An economic and process evaluation will also be conducted.

DISCUSSION

This trial will be the first to evaluate the effectiveness of this type of theory-based, blended learning intervention aimed at reducing antibiotic prescribing by primary care clinicians. Novel aspects include feedback of practice level data on antimicrobial resistance and prescribing, use of principles from motivational interviewing, training in enhanced communication skills that incorporates context-bound experience and reflection, and using antibiotic dispensing over one year (as opposed to antibiotic prescribing in a single consultation) as the main outcome.

Systematic Review of Interventions to Improve Prescribing

Objective:

To update 2 comprehensive reviews of systematic reviews on prescribing interventions and identify the latest evidence about the effectiveness of the interventions.

Data Sources:

Systematic searches for English-language reports of experimental and quasi-experimental research were conducted in PubMed(1951–May 2007). EMBASE (1974–March 2008), International Pharmaceutical Abstracts (1970–March 2008), and 11 other bibliographic databases of medical, social science, and business research. Following an initial title screening process and after selecting 6 specific intervention categories (identified from the previous reviews) in community settings, 2 reviewers independently assessed abstracts and then full studies for relevance and quality and extracted relevant data using formal assessment and data extraction tools. Results were then methodically incorporated into the findings of the 2 earlier reviews of systematic reviews.

Data Selection And Synthesis:

Twenty-nine of 26,314 articles reviewed were assessed to be of relevant, high-quality research. Audit and feedback, together with educational outreach visits, were the focus of the majority of recent, high-quality research into prescribing interventions. These interventions were also the most effective in improving prescribing practice. A smaller number of studies included a patient-mediated intervention; this intervention was not consistently effective. There is insufficient recent research into manual reminders to confidently update earlier reviews and there remains insufficient evidence to draw conclusions regarding the effectiveness of local consensus processes or multidisciplinary teams.

Conclusions:

Educational outreach as well as audit and feedback continue to dominate research into prescribing interventions. These 2 prescribing interventions also most consistently show positive results. Much less research is conducted into other types of interventions and there is still very little effort to systematically test why interventions do or do not work.
