Medical audit changes physicians' prescribing of antibiotics for respiratory tract infections

Over prescription of antibiotics in children with acute upper respiratory tract infections: A study on the knowledge, attitude and practices of non-specialized physicians in Egypt

BACKGROUND

Antimicrobial resistance (AMR) is currently one of the global public health threats. Increased antibiotic consumption in humans, animals, and agriculture has contributed directly to the spread of AMR. Upper respiratory tract infections (URIs) are one of the most common conditions treated by antibiotics, even if unnecessary as in cases of viral infections and self-limited conditions which represent the most cases of URIs. Investigating physicians' knowledge, attitudes, and practice regarding antibiotic prescriptions in children with acute URIs may reflect the problem of antibiotic over prescription. This study aims to assess the problem in our community and provide information for further planning of appropriate interventions to optimize antibiotic prescriptions.

METHODS

This is a cross-sectional study for all non-specialized physicians dealing with acute upper respiratory tract infections (URIs) in pediatrics sittings in Assiut district, Egypt. We used a self-administered questionnaire to assess physicians' knowledge, attitudes, and practice. In addition, four clinical vignettes addressing different URI scenarios were included in the questionnaire to assess the patterns of antibiotic prescriptions in common cases.

RESULTS

Our study included 153 physicians whose mean age was 32.2 ± 8.7, most of whom were pediatric residents in different health institutes in Assiut district. They had good knowledge as out of the 17 knowledge questions,the mean number of correct answers was 12.4 ± 2.9. Regarding their attitudes, mean attitude scores for inappropriate antibiotic prescribing were low. However, of those scores, the responsibility of others had the highest score (3.8 ± 0.61). Prescribing practice in special conditions of URIs showed that 80% of participants prescribed antibiotics if fever continued for more than five days and 61.4% if the child had a yellowish or greenish nasal discharge. Among 612 clinical vignettes, 326 contained antibiotic prescriptions (53.3%), and appropriate antibiotic prescriptions represented only 8.3% overall.

CONCLUSIONS

Physicians dealing with acute URIs in outpatients' clinics in the Assiut district have good knowledge about antibiotic use and resistance and demonstrate a good attitude toward appropriate antibiotic use. Although the percentage of inappropriate prescriptions in clinical vignettes in high, more research is required to investigate the factors of antibiotic inappropriate prescribing practice and non-adherence to guidelines. Also, it is essential to set up a national antibiotic stewardship program to improve antibiotic prescribing and contain antimicrobial resistance problems.

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.

A Conceptual Framework for Understanding and Reducing Overuse by Primary Care Providers

Primary care providers frequently recommend, administer, or prescribe health care services that are unlikely to benefit their patients. Yet little is known about how to reduce provider overuse behavior. In the absence of a theoretically grounded causal framework, it is difficult to predict the contexts under which different types of interventions to reduce provider overuse will succeed and under which they will fail. In this article, we present a framework based on the theory of planned behavior that is designed to guide overuse research and intervention development. We describe categories of primary care provider beliefs that lead to the formation of intentions to assess the appropriateness of services, and propose factors that may affect whether the presence of assessment intentions results in an appropriate recommendation. Interventions that have been commonly used to address provider overuse behavior are reviewed within the context of the framework.

Can the APO method be used for measuring soft data?: a pilot study

OBJECTIVES

The aims were to develop auditing according to the APO (Audit Project Odense) method for measuring soft data, exemplified by a holistic view, and to test the instrument.

DESIGN

A descriptive study of the development of an APO chart and a test registration.

SETTING

Primary health care, Blekinge County, Sweden.

SUBJECTS

Ten general practitioners (GPs) were invited to transform categories of the concept of a holistic view obtained in an earlier study, into 30 variables on an APO registration chart. The participants chose to study different kinds of knowledge as aspects of holistic care.

MAIN OUTCOME MEASURE

An APO registration chart and test of the instrument.

RESULTS

After three meetings the group had drawn up an APO registration chart supplemented with Likert scales. A pilot audit was performed. Eight doctors registered 255 consultations. In assessment of the patients' problems, factual medical knowledge was important in 83% of the cases, familiarity in 53%, and a capacity for judgement in 36%. In decision-making factual medical knowledge was used in 88% and capacity for judgement in 58%. A holistic view was necessary for the outcome in 43% and valuable in 25%. The GPs used the Likert scales in a majority of the cases.

CONCLUSIONS

In this first step in developing an instrument, the results indicate that the APO method could be an alternative for studying what happens in the consultation, and the occurrence of an abstract phenomenon such as the use of different kinds of knowledge as part of a holistic view.

Interventions to reduce unnecessary antibiotic prescribing: a systematic review and quantitative analysis

BACKGROUND

Overuse of antibiotics in ambulatory care persists despite many efforts to address this problem. We performed a systematic review and quantitative analysis to assess the effectiveness of quality improvement (QI) strategies to reduce antibiotic prescribing for acute outpatient illnesses for which antibiotics are often inappropriately prescribed.

RESEARCH DESIGN AND METHODS

We searched the Cochrane Collaboration's Effective Practice and Organisation of Care database, supplemented by MEDLINE and manual review of article bibliographies. We included randomized trials, controlled before-after studies, and interrupted time series. Two independent reviewers abstracted all data, and disagreements were resolved by consensus and discussion with a third reviewer. The primary outcome was the absolute reduction in the proportion of patients receiving antibiotics.

RESULTS

Forty-three studies reporting 55 separate trials met inclusion criteria. Most studies (N = 38) addressed prescribing for acute respiratory infections (ARIs). Among the 30 trials eligible for quantitative analysis, the median reduction in the proportion of subjects receiving antibiotics was 9.7% [interquartile range (IQR), 6.6-13.7%] over 6 months median follow-up. No single QI strategy or combination of strategies was clearly superior. However, active clinician education strategies trended toward greater effectiveness than passive strategies (P = 0.096). Compared with studies targeting specific conditions or patient populations, broad-based interventions extrapolated to larger community-level impacts on total antibiotic use, with savings of 17-117 prescriptions per 1000 person-years. Study methodologic quality was fair.

CONCLUSIONS

QI efforts are effective at reducing antibiotic use in ambulatory settings, although much room for improvement remains. Strategies using active clinician education and targeting management of all ARIs (rather than single conditions in single age groups) may yield larger reductions in community-level antibiotic use.

GPs' thoughts on prescribing medication and evidence-based knowledge: the benefit aspect is a strong motivator. A descriptive focus group study

OBJECTIVE

To describe GPs' thoughts of prescribing medication and evidence-based knowledge (EBM) concerning drug therapy.

DESIGN

Tape-recorded focus-group interviews transcribed verbatim and analysed using qualitative methods.

SETTING

GPs from the south-eastern part of Västra Götaland, Sweden.

SUBJECTS

A total of 16 GPs out of 178 from the south-eastern part of the region strategically chosen to represent urban and rural, male and female, long and short GP experience.

METHODS

Transcripts were analysed using a descriptive qualitative method.

RESULTS

The categories were: benefits, time and space, and expert knowledge. The benefit was a merge of positive elements, all aspects of the GPs' tasks. Time and space were limitations for GPs' tasks. EBM as a constituent of expert knowledge should be more customer adjusted to be able to be used in practice. Benefit was the most important category, existing in every decision-making situation for the GP. The core category was prompt and pragmatic benefit, which was the utmost benefit.

CONCLUSION

GPs' thoughts on evidence-based medicine and prescribing medication were highly related to reflecting on benefit and results. The interviews indicated that prompt and pragmatic benefit is important for comprehending their thoughts.

The meaning of quality work from the general practitioner's perspective: an interview study

Background

The quality of health care and its costs have been a subject of considerable attention and lively discussion. Various methods have been introduced to measure, assess, and improve the quality of health care. Many professionals in health care have criticized quality work and its methods as being unsuitable for health care. The aim of the study was to obtain a deeper understanding of the meaning of quality work from the general practitioner's perspective.

Methods

Fourteen general practitioners, seven women and seven men, were interviewed with the aid of a semi-structured interview guide about their experience of quality work. The interviews were tape-recorded and transcribed verbatim. Data collection and analysis were guided by a phenomenological approach intended to capture the essence of the statements.

Results

Two fundamentally different ways to view quality work emerged from the statements: A pronounced top-down perspective with elements of control, and an intra-profession or bottom-up perspective. From the top-down perspective, quality work was described as something that infringes professional freedom. From the bottom-up perspective the statements described quality work as a self-evident duty and as a professional attitude to the medical vocation, guided by the principles of medical ethics. Follow-up with a bottom-up approach is best done in internal processes, with the profession itself designing structures and methods based on its own needs.

Conclusions

The study indicates that general practitioners view internal follow-up as a professional obligation but external control as an imposition. This opposition entails a difficulty in achieving systematism in follow-up and quality work in health care. If the statutory standards for systematic quality work are to gain a real foothold, they must be packaged in such a way that general practitioners feel that both perspectives can be reconciled.

Improving antibiotic selection: a systematic review and quantitative analysis of quality improvement strategies

OBJECTIVE

We sought to assess which interventions are most effective at improving the prescribing of recommended antibiotics for acute outpatient infections.

DESIGN AND METHODS

We undertook a systematic review with quantitative analysis of the Cochrane Registry Effective Practice and Organization of Care (EPOC) database, supplemented by MEDLINE and hand-searches. Inclusion criteria included clinical trials with contemporaneous or strict historical controls that reported data on antibiotic selection in acute outpatient infections. The effect size of studies with different intervention types were compared using nonparametric statistics. To maximize comparability between studies, quantitative analysis was restricted to studies that reported absolute changes in the amount of or percent compliance with recommended antibiotic prescribing.

RESULTS

Twenty-six studies reporting 33 trials met inclusion criteria. Most interventions used clinician education alone or in combination with audit and feedback. Among the 22 comparisons amenable to quantitative analysis, recommended antibiotic prescribing improved by a median of 10.6% (interquartile range [IQR] 3.4-18.2%). Trials evaluating clinician education alone reported larger effects than interventions combining clinician education with audit and feedback (median effect size 13.9% [IQR 8.6-21.6%] vs. 3.4% [IQR 1.8-9.7%], P = 0.03). This result was confounded by trial sample size, as trials having a smaller number of participating clinicians reported larger effects and were more likely to use clinician education alone. Active forms of education, sustained interventions, and other features traditionally associated with successful quality improvement interventions were not associated with effect size and showed no evidence of confounding the association between clinician education-only strategies and outcome.

CONCLUSIONS

Multidimensional interventions using audit and feedback to improve antibiotic selection were less effective than interventions using clinician education alone. Although confounding may partially account for this finding, our results suggest that enhancing the intensity of a focused intervention may be preferable to a less intense, multidimensional approach.

Evaluation of a national quality use of medicines service in Australia: an evolving model

RATIONALE

To describe the first phase of a global evaluation framework for the National Prescribing Service (NPS), with a focus on services for health professionals, and in particular highlight the lessons learnt from evaluation around the establishment and implementation of this national program.

METHODS

The agreed evaluation framework used mixed methods focused around a series of evaluation questions, aimed at measuring the overall effect of this new organization as well as the individual programs within it. The evaluation questions were determined a priori and were based on the objectives established by the organization in its first year of operation. A detailed analyses has been completed of: the process, scope and reach of program delivery using both quantitative and qualitative measures; changes in attitudes and knowledge measured through key informant interviews and surveys of professional groups and consumers; and changes in prescribing behaviour and savings to the Pharmaceutical Benefits Scheme (PBS) through analysis of prescription data. The evaluation period for this report was mid-1998 to mid-2004.

RESULTS

The NPS has successfully implemented a complex, multi-faceted program across Australia. From 1998 to 2004, in addition to print material provided to all general practitioners (GPs) and pharmacists, 90% of all GPs have been actively involved in one or more educational activity; 116 of 120 divisions of general practice have coordinated local NPS programs; and 9% of pharmacists have actively participated in at least one educational activity. Sixty per cent of GPs and pharmacists rated the printed educational materials as good or very good. In the last three years, the NPS activities have generated savings in the range of $121-163 million to the PBS, owing to changes in prescribing practices.

CONCLUSION

The national evaluation framework has informed program delivery and ongoing design and development. Continued refinement of existing evaluation methods and further exploration of new techniques will remain a priority for the organization.

Interventions to improve antibiotic prescribing practices in ambulatory care

BACKGROUND

The development of resistance to antibiotics by many important human pathogens has been linked to exposure to antibiotics over time. The misuse of antibiotics for viral infections (for which they are of no value) and the excessive use of broad spectrum antibiotics in place of narrower spectrum antibiotics have been well-documented throughout the world. Many studies have helped to elucidate the reasons physicians use antibiotics inappropriately.

OBJECTIVES

To systematically review the literature to estimate the effectiveness of professional interventions, alone or in combination, in improving the selection, dose and treatment duration of antibiotics prescribed by healthcare providers in the outpatient setting; and to evaluate the impact of these interventions on reducing the incidence of antimicrobial resistant pathogens.

SEARCH STRATEGY

We searched the Cochrane Effective Practice and Organisation of Care Group (EPOC) specialized register for studies relating to antibiotic prescribing and ambulatory care. Additional studies were obtained from the bibliographies of retrieved articles, the Scientific Citation Index and personal files.

SELECTION CRITERIA

We included all randomised and quasi-randomised controlled trials (RCT and QRCT), controlled before and after studies (CBA) and interrupted time series (ITS) studies of healthcare consumers or healthcare professionals who provide primary care in the outpatient setting. Interventions included any professional intervention, as defined by EPOC, or a patient-based intervention.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed study quality.

MAIN RESULTS

Thirty-nine studies examined the effect of printed educational materials for physicians, audit and feedback, educational meetings, educational outreach visits, financial and healthcare system changes, physician reminders, patient-based interventions and multi-faceted interventions. These interventions addressed the overuse of antibiotics for viral infections, the choice of antibiotic for bacterial infections such as streptococcal pharyngitis and urinary tract infection, and the duration of use of antibiotics for conditions such as acute otitis media. Use of printed educational materials or audit and feedback alone resulted in no or only small changes in prescribing. The exception was a study documenting a sustained reduction in macrolide use in Finland following the publication of a warning against their use for group A streptococcal infections. Interactive educational meetings appeared to be more effective than didactic lectures. Educational outreach visits and physician reminders produced mixed results. Patient-based interventions, particularly the use of delayed prescriptions for infections for which antibiotics were not immediately indicated effectively reduced antibiotic use by patients and did not result in excess morbidity. Multi-faceted interventions combining physician, patient and public education in a variety of venues and formats were the most successful in reducing antibiotic prescribing for inappropriate indications. Only one of four studies demonstrated a sustained reduction in the incidence of antibiotic-resistant bacteria associated with the intervention.

AUTHORS' CONCLUSIONS

The effectiveness of an intervention on antibiotic prescribing depends to a large degree on the particular prescribing behaviour and the barriers to change in the particular community. No single intervention can be recommended for all behaviours in any setting. Multi-faceted interventions where educational interventions occur on many levels may be successfully applied to communities after addressing local barriers to change. These were the only interventions with effect sizes of sufficient magnitude to potentially reduce the incidence of antibiotic-resistant bacteria. Future research should focus on which elements of these interventions are the most effective. In addition, patient-based interventions and physician reminders show promise and innovative methods such as these deserve further study.

Effect of educational intervention on antibiotic prescription practices for upper respiratory infections in children: a multicentre study

OBJECTIVES

To evaluate the impact of an educational intervention on judicious antibiotic prescription for upper respiratory diseases in children.

METHODS

A multicentre before-and-after study was conducted in five major community child healthcentres in Israel. Antibiotic prescription data were collected for all visits of patients aged 3 months to 18 years with a diagnosis of acute otitis media, tonsillopharyngitis, sinusitis or upper respiratory tract infection from November 1999 through February 2000 (pre-intervention period) and from November 2000 through February 2001 (post-intervention period). The intervention consisted of a 1 day seminar on the diagnosis and judicious treatment of respiratory tract infections in children according to the recommendations of the Centers of Disease Control and Prevention. The patient files were reviewed for patient characteristics, specific respiratory disease, and specific antibiotics prescribed. The main outcome measures were the rates and appropriateness of antibiotic prescribing for the different respiratory diseases before and after an educational intervention for practising paediatricians.

RESULTS

A total of 4580 clinic visits were eligible for analysis in the pre-intervention period and 4364 in the post-intervention period. From the pre- to the post-intervention period, the odds ratio for appropriate antibiotic treatment was 1.8 for acute otitis media (95% CI 1.52-2.11, P < 0.01) and 1.35 for pharyngitis (95% CI 1.13-1.61, P < 0.01). Overall, use of antibiotics for acute otitis media decreased from 93% to 87.4% (P < 0.05), and for upper respiratory tract infection, from 13.8% to 11.5% (P < 0.05). There were no significant changes in these factors for sinusitis.

CONCLUSIONS

A targeted educational intervention can improve antibiotic prescription practices for respiratory infections in children and decrease unnecessary antibiotic use. Such studies can also pinpoint areas that require further attention.

Otitis media, tympanostomy tube placement, and use of antibiotics. Cross-sectional community study repeated after five years

OBJECTIVE

To investigate potential links between antimicrobial drug use for acute otitis media (AOM) and tympanostomy tube placements, and the relationship between parental views and physician antimicrobial prescribing habits.

DESIGN

Cross-sectional community study repeated after five years.

SUBJECTS

Representative samples of children aged 1-6 years in four well-defined communities in Iceland, examined in 2003 (n = 889) and 1998 (n = 804).

MAIN OUTCOME MEASURES

Prevalence of antimicrobial treatments for AOM, tympanostomy tube placements, and parental expectations of antimicrobial treatment. Results. Tympanostomy tubes had been placed at some time in 34% of children in 2003, as compared with 30% in 1998. A statistically significant association was found between tympanostomy tube placement rate and antimicrobial use for AOM in 2003. In the area where antimicrobial use for AOM was lowest in 1998, drug use had further diminished significantly. At the same time, the prevalence of tympanostomy tube placements had diminished from 26% to 17%. Tube placements had increased significantly, from 35% to 44%, in the area where antimicrobial use for AOM was highest. Parents in the area where antimicrobial consumption was lowest and narrow spectrum antimicrobials were most often used were less likely to be in favour of antimicrobial treatment.

CONCLUSIONS

Comparison between communities showed a positive correlation between antimicrobial use for AOM and tympanostomy tube placements. The study supports a restrictive policy in relation to prescriptions of antibiotics for AOM. It also indicates that well-informed parents predict a restrictive prescription policy.

National Prescribing Service: creating an implementation arm for national medicines policy

Medicines make an essential contribution to the health of the community, but rapidly rising drug budgets have caused governments to seek ways of ensuring this expenditure results in value for money. The National Prescribing Service was established against this background to implement a quality use of medicines service as part of the National Medicines Policy. A range of programmes that attempt to use evidence-based strategies to deliver evidence-based messages have been established. These use multifaceted interventions, such as newsletters, prescriber feedback, clinical audit and educational visiting, that are provided both centrally, through the national office, and locally, through Divisions of General Practice. The work is underpinned by an evaluation strategy that incorporates strong qualitative elements as well as an emphasis on time-series analyses for changes in drug utilization. Some 80% of Australian general practitioners have voluntarily participated in activities such as educational visiting and clinical audit within the National Prescribing Service programmes. New programmes for the community and consumers will be coordinated with the work that has become well established within general practice.

The Authority/Pharmacotherapy Care model: an explanatory model of the drug use process in primary care

BACKGROUND

Drug utilization studies have proliferated and many variants exist. Few models have been presented that account for all of the different types of studies and approaches.

PURPOSE

This article presents the Authority/Pharmacotherapy Care model, a structural-functional model of the drug use process that illustrates the factors involved in drug utilization and the relationships between factors. The concepts of authority and transfer of authority underlie the relationships.

METHODS

The drug use process is presented at the microlevel from the viewpoint of an individual who requires treatment with prescription drugs. The various categories of activity/authority (ie, level of patient care) are those of the individual, physician, pharmacist, patient, and drug. Influencing factors, both internal and external, impact upon each level of care. Three aspects must be considered at each level, which are structures, processes, and outcomes, according to Donabedian's model.

RESULTS

The result is a structural-functional model that depicts all of the major points in the drug use process, which might be used as a framework to categorize drug utilization studies.

CONCLUSIONS

This model may be used to represent the drug use process, identify the types of drug use studies, determine pertinent factors involved in the process, understand the relationships between factors, and help in evaluating drug use.

Influence of self-registration on audit participants and their non-participating colleagues. A retrospective study of medical records concerning prescription patterns

OBJECTIVE

To compare participants and non-participants early in the process of an audit on treatment of respiratory tract infections (RTIs) and to analyse any effect of the actual self-registration on the prescription of antibiotics in both groups.

DESIGN

All 80 general practitioners (GPs) at 14 health centres were invited to audit their use of antibiotics and 45 agreed to participate. There were both participants and non-participants at all centres. Data were collected retrospectively from the electronic patient records of all visits for RTI during five periods including the self-registration period. Comparisons were made over time within and between the groups.

SETTING

Primary health care in Blekinge county, Southern Sweden.

SUBJECTS

80 GPs: 45 participants and 35 non-participants.

MAIN OUTCOME MEASURE

Proportion of patients with RTI who received antibiotics.

RESULTS

At the start, the difference in prescription frequency between participants and non-participants was six percentage points (RR = 0.92; 95% CI = 0.87-0.97), and at the end seven percentage points (0.88; 0.81-0.95). The proportion of RTIs treated with antibiotics fell for both groups, (0.86; 0.80-0.92 and 0.90; 0.83-0.97, respectively).

CONCLUSIONS

GPs who chose to take part in the audit had a different prescription pattern from the non-participants right from the start. Both groups reduced their prescription of antibiotics during the study period. Either the registration had no effect on the participants or it had an effect on both the participants and the non-participants.

Utilisation of antibiotics in young children: opposite relationships to adult educational levels in Danish and Swedish counties

BACKGROUND

Antibiotic utilisation varies profoundly among and within countries, and the extent of antibiotic utilisation correlates with the frequency of bacterial resistance, particularly among children. Hence, it is important to assess which factors may influence prescribing. In addition to variations in morbidity, health-care organisation, drug regulatory and supply systems, prescriber's attitudes, parents' behaviour, attitudes and socio-economic positions seem important. We compared socio-economic position (educational level of adults) and antibiotic utilisation in children in the municipalities within a Danish and a Swedish county which are geographically close, have similar social and economic development, and similar drug regulatory and supply systems.

METHODS

Data on antibiotic utilisation (1998), expressed in defined daily doses per 1000 inhabitants per day (DDD/TID), were obtained from the Copenhagen County Health Insurance register and from the National Corporation of Swedish Pharmacies. Data on municipal educational levels were obtained from Statistics Denmark and Statistics Sweden.

RESULTS

The utilisation of antibiotics in 0- to 6-year-old children was higher in the Swedish than in the Danish county but varied between the municipalities within both the Swedish (9.6-17.7 DDD/TID) and the Danish (8.0-12.9 DDD/TID) counties. Most notably, utilisation rates correlated negatively with the education levels in the Danish (r=-0.539, P=0.021) but positively in the Swedish (r=+0.390, P=0.025) municipalities.

CONCLUSION

The observed variations in antibiotic prescribing may reflect different parental and/or prescriber attitudes towards use of antibiotics and they emphasise that antibiotic prescribing is influenced by factors other than the prevalence of bacterial infections. Relationships between socio-economic position (educational level) and drug utilisation should not be generalised from one area to another.

Do clinical practice education groups result in sustained change in GP prescribing?

BACKGROUND

Concern has been expressed at the poor uptake of evidence into clinical practice. This is despite the fact that continuing education is an embedded feature of quality assurance in general practice. There are a variety of clinical practice education methods available for dissemination of new evidence. Recent systematic reviews indicate that the effectiveness of these different strategies is extremely variable.

OBJECTIVE

Our aim was to determine whether a peer-led small group education pilot programme used to promote rational GP prescribing is an effective tool in changing practice when added to prescribing audit and feedback, academic detailing and educational bulletins, and to determine whether any effect seen decays over time.

METHODS

A retrospective analysis of a controlled trial of a small group education strategy with 24 month follow-up was carried out. The setting was an independent GPs association (IPA) of 230 GPs in the Christchurch New Zealand urban area. All intervention and control group GPs were already receiving prescribing audit and feedback, academic detailing and educational bulletins. The intervention group were the first 52 GPs to respond to an invitation to pilot the project. Two control groups were used, one group who joined the pilot later and a second group which included all other GPs in the IPA. The main outcome measures were targeted prescribing data for 12 months before and 24 months after each of four education sessions.

RESULTS

An effect in the expected direction was seen in six of the eight key messages studied. This effect was statistically significant for five of the eight messages studied. The effect size varied between 7 and 40%. Where a positive effect was seen, the effect decayed with time but persisted to a significant level for 6-24 months of observation.

CONCLUSION

The results support a positive effect of the education strategy on prescribing behaviour in the intervention group for most outcomes measured. The effect seen is statistically significant, sustained and is in addition to any effect of the other pharmaceutical educational initiatives already undertaken by the IPA.
