Improving drug use through continuing education: a randomized controlled trial in Zambia

Reporting of costs and economic impacts in randomized trials of de-implementation interventions for low-value care: a systematic scoping review

BACKGROUND

De-implementation of low-value care can increase health care sustainability. We evaluated the reporting of direct costs of de-implementation and subsequent change (increase or decrease) in health care costs in randomized trials of de-implementation research.

METHODS

We searched MEDLINE and Scopus databases without any language restrictions up to May 2021. We conducted study screening and data extraction independently and in duplicate. We extracted information related to study characteristics, types and characteristics of interventions, de-implementation costs, and impacts on health care costs. We assessed risk of bias using a modified Cochrane risk-of-bias tool.

RESULTS

We screened 10,733 articles, with 227 studies meeting the inclusion criteria, of which 50 included information on direct cost of de-implementation or impact of de-implementation on health care costs. Studies were mostly conducted in North America (36%) or Europe (32%) and in the primary care context (70%). The most common practice of interest was reduction in the use of antibiotics or other medications (74%). Most studies used education strategies (meetings, materials) (64%). Studies used either a single strategy (52%) or were multifaceted (48%). Of the 227 eligible studies, 18 (8%) reported on direct costs of the used de-implementation strategy; of which, 13 reported total costs, and 12 reported per unit costs (7 reported both). The costs of de-implementation strategies varied considerably. Of the 227 eligible studies, 43 (19%) reported on impact of de-implementation on health care costs. Health care costs decreased in 27 studies (63%), increased in 2 (5%), and were unchanged in 14 (33%).

CONCLUSION

De-implementation randomized controlled trials typically did not report direct costs of the de-implementation strategies (92%) or the impacts of de-implementation on health care costs (81%). Lack of cost information may limit the value of de-implementation trials to decision-makers.

Continuing education meetings and workshops: effects on professional practice and healthcare outcomes

BACKGROUND

Educational meetings are used widely by health personnel to provide continuing medical education and to promote implementation of innovations or translate new knowledge to change practice within healthcare systems. Previous reviews have concluded that educational meetings can result in small changes in behaviour, but that effects vary considerably. Investigations into which characteristics of educational meetings might lead to greater impact have yielded varying results, and factors that might explain heterogeneity in effects remain unclear. This is the second update of this Cochrane Review.

OBJECTIVES

• To assess the effects of educational meetings on professional practice and healthcare outcomes • To investigate factors that might explain the heterogeneity of these effects SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, ERIC, Science Citation Index Expanded (ISI Web of Knowledge), and Social Sciences Citation Index (last search in November 2016).

SELECTION CRITERIA

We sought randomised trials examining the effects of educational meetings on professional practice and patient outcomes.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed risk of bias. One review author assessed the certainty of evidence (GRADE) and discussed with a second review author. We included studies in the primary analysis that reported baseline data and that we judged to be at low or unclear risk of bias. For each comparison of dichotomous outcomes, we measured treatment effect as risk difference adjusted for baseline compliance. We expressed adjusted risk difference values as percentages, and we noted that values greater than zero favour educational meetings. For continuous outcomes, we measured treatment effect as per cent change relative to the control group mean post test, adjusted for baseline performance; we expressed values as percentages and noted that values greater than zero favour educational meetings. We report means and 95% confidence intervals (CIs) and, when appropriate, medians and interquartile ranges to facilitate comparisons to previous versions of this review. We analysed professional and patient outcomes separately and analysed 22 variables that were hypothesised a priori to explain heterogeneity. We explored heterogeneity by using univariate meta-regression and by inspecting violin plots.

MAIN RESULTS

We included 215 studies involving more than 28,167 health professionals, including 142 new studies for this update. Educational meetings as the single intervention or the main component of a multi-faceted intervention compared with no intervention • Probably slightly improve compliance with desired practice when compared with no intervention (65 comparisons, 7868 health professionals for dichotomous outcomes (adjusted risk difference 6.79%, 95% CI 6.62% to 6.97%; median 4.00%; interquartile range 0.29% to 13.00%); 28 comparisons, 2577 health professionals for continuous outcomes (adjusted relative percentage change 44.36%, 95% CI 41.98% to 46.75%; median 20.00%; interquartile range 6.00% to 65.00%)) • Probably slightly improve patient outcomes compared with no intervention (15 comparisons, 2530 health professionals for dichotomous outcomes (adjusted risk difference 3.30%, 95% CI 3.10% to 3.51%; median 0.10%; interquartile range 0.00% to 4.00%); 28 comparisons, 2294 health professionals for continuous outcomes (adjusted relative percentage change 8.35%, 95% CI 7.46% to 9.24%; median 2.00%; interquartile range -1.00% to 21.00%)) The certainty of evidence for this comparison is moderate. Educational meetings alone compared with other interventions • May improve compliance with desired practice when compared with other interventions (6 studies, 1402 health professionals for dichotomous outcomes (adjusted risk difference 9.99%, 95% CI 9.47% to 10.52%; median 16.5%; interquartile range 0.80% to 16.50%); 2 studies, 72 health professionals for continuous outcomes (adjusted relative percentage change 12.00%, 95% CI 9.16% to 14.84%; median 12.00%; interquartile range 0.00% to 24.00%)) No studies met the inclusion criteria for patient outcome measurements. The certainty of evidence for this comparison is low. Interactive educational meetings compared with didactic (lecture-based) educational meetings • We are uncertain of effects on compliance with desired practice (3 studies, 370 health professionals for dichotomous outcomes; 1 study, 192 health professionals for continuous outcomes) or on patient outcomes (1 study, 54 health professionals for continuous outcomes), as the certainty of evidence is very low Any other comparison of different formats and durations of educational meetings • We are uncertain of effects on compliance with desired practice (1 study, 19 health professionals for dichotomous outcomes; 1 study, 20 health professionals for continuous outcomes) or on patient outcomes (1 study, 113 health professionals for continuous outcomes), as the certainty of evidence is very low. Factors that might explain heterogeneity of effects Meta-regression suggests that larger estimates of effect are associated with studies judged to be at high risk of bias, with studies that had unit of analysis errors, and with studies in which the unit of analysis was the provider rather than the patient. Improved compliance with desired practice may be associated with: shorter meetings; poor baseline compliance; better attendance; shorter follow-up; professionals provided with additional take-home material; explicit building of educational meetings on theory; targeting of low- versus high-complexity behaviours; targeting of outcomes with high versus low importance; goal of increasing rather than decreasing behaviour; teaching by opinion leaders; and use of didactic versus interactive teaching methods. Pre-specified exploratory analyses of behaviour change techniques suggest that improved compliance with desired practice may be associated with use of a greater number of behaviour change techniques; goal-setting; provision of feedback; provision for social comparison; and provision for social support. Compliance may be decreased by the use of follow-up prompts, skills training, and barrier identification techniques.

AUTHORS' CONCLUSIONS

Compared with no intervention, educational meetings as the main component of an intervention probably slightly improve professional practice and, to a lesser extent, patient outcomes. Educational meetings may improve compliance with desired practice to a greater extent than other kinds of behaviour change interventions, such as text messages, fees, or office systems. Our findings suggest that multi-strategy approaches might positively influence the effects of educational meetings. Additional trials of educational meetings compared with no intervention are unlikely to change the review findings; therefore we will not further update this review comparison in the future. However, we note that randomised trials comparing different types of education are needed.

Is 'Health for All' synonymous with 'antibiotics for all': changes in antibiotic prescribing in a performance-based financing pilot in Zanzibar

Universal Health Coverage, to meet the Sustainable Development Goal of 'Health for All', aims to increase the access of preventative and curative care services, particularly to the poor and vulnerable. However, the very provision of curative services by health providers in the primary care setting in low-income countries is considered one of the major drivers of antimicrobial resistance. The Zanzibar Ministry of Health introduced performance-based financing (PBF) in 2 of 10 Health Districts in July 2013. Payments to health facilities and staff were on a fee-for-service basis using 'direct quality indicators'. Results of an evaluation of secondary data of two indicators, 'treatment according to guidelines' and 'antibiotics prescribed according to guidelines' from 31 Primary Health Care Units in the two PBF pilot districts are compared with 28 in non-PBF districts. The proportion of patients treated with an antibiotic not in accordance with treatment guidelines after the introduction of PBF fell to 2%, 6% and 5% in 2014, 2015 and 2016, respectively, compared with an increase from 25% (2013) to 31% (2014) and 22% (2015, 2016) in non-PBF facilities. The key take-home messages from this evaluation are firstly that 'direct quality indicators' to improve the use of treatment guidelines, introduced into a national PBF reform that includes financial incentives and rigorous verification of register entries, have the potential to significantly reduce inappropriate use of antibiotics in high population density settings in Africa. Secondly, for a sustained reduction in the overall proportion of unnecessary antibiotic prescriptions rigorous monitoring of health worker behaviour is required to address changes in prescribing practice. A well-designed and monitored PBF with 'direct quality indicators' has the potential to ensure that 'Health for All', in terms of increased access to primary health services is not synonymous with 'antibiotics for all'.

Prescribing indicators at primary health care centers within the WHO African region: a systematic analysis (1995-2015)

Background

Rational medicine use is essential to optimize quality of healthcare delivery and resource utilization. We aim to conduct a systematic review of changes in prescribing patterns in the WHO African region and comparison with WHO indicators in two time periods 1995–2005 and 2006–2015.

Methods

Systematic searches were conducted in PubMed, Scopus, Web of science, Africa-Wide Nipad, Africa Journals Online (AJOL), Google scholar and International Network for Rational Use of Drugs (INRUD) Bibliography databases to identify primary studies reporting prescribing indicators at primary healthcare centres (PHCs) in Africa. This was supplemented by a manual search of retrieved references. We assessed the quality of studies using a 14-point scoring system modified from the Downs and Black checklist with inclusions of recommendations in the WHO guidelines.

Results

Forty-three studies conducted in 11 African countries were included in the overall analysis. These studies presented prescribing indicators based on a total 141,323 patient encounters across 572 primary care facilities. The results of prescribing indicators were determined as follows; average number of medicines prescribed per patient encounter = 3.1 (IQR 2.3–4.8), percentage of medicines prescribed by generic name =68.0 % (IQR 55.4–80.3), Percentage of encounters with antibiotic prescribed =46.8 % (IQR 33.7–62.8), percentage of encounters with injection prescribed =25.0 % (IQR 18.7–39.5) and the percentage of medicines prescribed from essential medicines list =88.0 % (IQR 76.3–94.1). Prescribing indicators were generally worse in private compared with public facilities. Analysis of prescribing across two time points 1995–2005 and 2006–2015 showed no consistent trends.

Conclusions

Prescribing indicators for the African region deviate significantly from the WHO reference targets. Increased collaborative efforts are urgently needed to improve medicine prescribing practices in Africa with the aim of enhancing the optimal utilization of scarce resources and averting negative health consequences.

What Happens When "Germs Don't Get Killed and They Attack Again and Again": Perceptions of Antimicrobial Resistance in the Context of Diarrheal Disease Treatment Among Laypersons and Health-Care Providers in Karachi, Pakistan

In south Asia, where diarrhea is common and antibiotics are accessible without prescription, antimicrobial resistance is an emerging and serious problem. However, beliefs and behaviors related to antimicrobial resistance are poorly understood. We explored laypersons' and health-care providers' (HCP) awareness and perceptions of antimicrobial resistance in the context of treatment of adult diarrheal disease in Karachi, Pakistan. In-depth, open-ended interviews were conducted with 40 laypersons and 45 HCPs in a lower-middle-class urban neighborhood. Interviews conducted in Urdu were audiotaped, transcribed, translated, and coded using applied thematic analysis. Slightly over half of laypersons and two-thirds of HCPs were aware that antimicrobial medication could lose effectiveness, but misperceptions were common. Laypersons and HCPs often believed that "the body becomes immune" or "bacteria attack more strongly" if medications are taken "improperly." Another prevalent theme was that causes and effects of antimicrobial resistance are limited to the individual taking the antimicrobial medication and to the specific diarrheal episode. Participants often attributed antimicrobial resistance to patient behaviors; HCP behavior was rarely discussed. Less than half of the HCPs were aware of treatment guidelines. To combat antimicrobial resistance in urban Pakistan, a health systems strategy and community-supported outreach campaigns on appropriate antimicrobial use are needed.

Knowledge and perceptions of asthma in Zambia: a cross-sectional survey

BACKGROUND

Zambia is currently experiencing an epidemiological transition, from communicable to non-communicable diseases. The annual rate of physician-diagnosed asthma is estimated at 3 %. However, the general public's knowledge of asthma symptoms and signs, and their perception of asthma remain unknown. A survey was conducted aiming to determine knowledge and perceptions of asthma among Zambians.

METHODS

Adults and adolescents attending four clinics in the capital, Lusaka, were surveyed using a standardized questionnaire from July 2011 to March 2012.

RESULTS

Data from 1,540 participants (mean age 30.7 years, 65% female) were collected. Most patients (74%) were living in low-cost housing. One hundred and sixteen (7.6%) participants reported either a medical diagnosis of asthma or currently taking asthma medications. The most frequent asthma symptoms reported were wheezing (88%), and waking up at night with either shortness of breath (85%), chest tightness (85%), or cough (67%). Medications used to treat asthma were mostly oral short-acting beta-agonists (SABA) (59%), inhaled SABA (30.2%) and antibiotics (29.8%). Inhaled steroids were only used by 16.4% while less than 1% were on long-acting beta-agonists (LABA). Many misconceptions were identified among the entire surveyed population with only 54.7% believing hospitalisations are not preventable, 54.7% believing asthma symptoms can be prevented with the right medications and 37% believing inhalers are addictive. Nearly 60% thought that people with asthma cannot exercise or play hard. Significantly more individuals with asthma compared to those without thought tablets are better than inhalers for the treatment of asthma (46% vs 30%).

CONCLUSIONS

We conclude that knowledge on asthma is poor in Zambia, where there remains many misconceptions on asthma and its management.

Impact of Contextual Factors on the Effect of Interventions to Improve Health Worker Performance in Sub-Saharan Africa: Review of Randomised Clinical Trials

BACKGROUND

Africa bears 24% of the global burden of disease but has only 3% of the world's health workers. Substantial variation in health worker performance adds to the negative impact of this significant shortfall. We therefore sought to identify interventions implemented in sub-Saharan African aiming to improve health worker performance and the contextual factors likely to influence local effectiveness.

METHODS AND FINDINGS

A systematic search for randomised controlled trials of interventions to improve health worker performance undertaken in sub-Saharan Africa identified 41 eligible trials. Data were extracted to define the interventions' components, calculate the absolute improvement in performance achieved, and document the likelihood of bias. Within-study variability in effect was extracted where reported. Statements about contextual factors likely to have modified effect were subjected to thematic analysis. Interventions to improve health worker performance can be very effective. Two of the three trials assessing mortality impact showed significant reductions in death rates (age<5 case fatality 5% versus 10%, p<0.01; maternal in-hospital mortality 6.8/1000 versus 10.3/1000; p<0.05). Eight of twelve trials focusing on prescribing had a statistically significant positive effect, achieving an absolute improvement varying from 9% to 48%. However, reported range of improvement between centres within trials varied substantially, in many cases exceeding the mean effect. Nine contextual themes were identified as modifiers of intervention effect across studies; most frequently cited were supply-line failures, inadequate supervision or management, and failure to follow-up training interventions with ongoing support, in addition to staff turnover.

CONCLUSIONS

Interventions to improve performance of existing staff and service quality have the potential to improve patient care in underserved settings. But in order to implement interventions effectively, policy makers need to understand and address the contextual factors which can contribute to differences in local effect. Researchers therefore must recognise the importance of reporting how context may modify effect size.

Combining user fees exemption with training and supervision helps to maintain the quality of drug prescriptions in Burkina Faso

To improve access to health care services, an intervention was implemented in Burkina Faso granting full exemption from user fees. Two further components, staff training and supervision, were added to support the intervention. Our aim in this study was to examine how this tripartite intervention affected the quality of drug prescriptions. Using a mixed methodology, we first conducted an interrupted time series over 24 months. Nine health centres were studied that had previously undergone a process analysis. A total of 14 956 prescriptions for children 0-4 years old were selected by interval sampling from the visit registries from 1 year before to 1 year after the intervention's launch. We then interviewed 14 prescribers. We used three World Health Organization (WHO) indicators to assess drug prescription quality. Analysis was carried out using linear regression and logistic regression. The prescribers' statements underwent content analysis, to understand their perceptions and changes in their practice since the subsidy's introduction. One effect of the intervention was a reduced use of injections (odd ratio (OR) = 0.28 [0.17; 0.46]) in cases of acute lower respiratory tract infections (ALRTI) without comorbidity. Another was a reduction in the inappropriate use of antibiotics in malaria without comorbidity (OR = 0.48 [0.33; 0.70]). The average number of drugs prescribed also decreased (coefficient = -0.14 [-0.20; -0.08]) in cases of ALRTI without comorbidity. The prescribers reported that their practices were either maintained or improved. The user fees exemption programme, combined with health staff training and supervision, did not lead to any deterioration in the quality of drug prescriptions.

Medical rehabilitation of leprosy patients discharged home in abia and ebonyi States of Nigeria

OBJECTIVES

To examine the extent to which medical coverage is available to discharged leprosy patients in communities. Evidence has shown that after care services, follow-up visits and national disease prevention programs are important components of medical rehabilitation to leprosy patients discharged home after treatment. Denying them accessibility to these services could expose them to multiple disabilities as well as several disease conditions including HIV/AIDS. These adverse health conditions could be averted if health workers extend healthcare services to discharged leprosy patients. This study was conducted to examine the extent to which discharged leprosy patients have access to healthcare services in the communities.

METHODS

All 33 leprosy patients who were fully treated with multi-drug therapy (MDT) and discharged home in the two leprosy settlements in Abia and Ebonyi States of Nigeria were included in this study. The list of discharged leprosy patients studied and their addresses were provided by the leprosy settlements where they were treated. Also, snowball-sampling method was used to identify some of the leprosy patients whose addresses were difficult to locate in the communities. Instruments for data collection were questionnaire, interview guide and checklist. These were administered because respondents were essentially those with no formal education. Analysis of data was done quantitatively and qualitatively.

RESULTS

Findings showed that 20 (60.6%) of discharged patients did not receive health programs like HIV/AIDS prevention or family planning. Also, follow-up visits and after-care services were poor. About 14 (42.4%) of the patients live in dirty and overcrowded houses. On the whole, discharged patients were poorly medically rehabilitated (mean score: 4.7±1.1 out of total score of 7).

CONCLUSION

Denying discharged leprosy patients opportunity of accessing health care services could increase prevalence of infectious diseases including HIV/AIDS among them. There is need to extend national prevention programs, follow-up visits, after-care services and free treatment to discharged patients in the communities.

Effect of adopting integrated management of childhood illness guidelines on drug use at a primary health care center: a case study from Egypt

BACKGROUND

Integrated Management of Childhood Illness (IMCI) is a cost- effective strategy that improves the quality of care through the use of evidence- based management protocols for the most common causes of childhood death and illness. Evidence- based clinical guidelines are critical to promoting rational use of medicines. Despite the large number of studies that assessed process and outcome of care delivered to children utilizing IMCI protocol, there is a scarcity of studies that assessed the effect of adopting IMCI on the drug use.

AIMS

To examine the impact of adopting IMCI guidelines on drug use at one of the primary health care (PHC) centers, Alexandria, Egypt.

SETTINGS AND DESIGN

Retrospective cohort study, conducted in clinic "A" not adopting IMCI guidelines and clinic "B" adopting IMCI guidelines at one of the PHC centers in Alexandria, Egypt for the period from January-- end of June 2010.

MATERIALS AND METHODS

A data collection sheet was designed to collect the required variables (based on WHO/ INRUD selected drug use indicators) from the medical records of children under five years.

STATISTICAL ANALYSIS USED

SPSS version 16 was used. Percentages, means, and standard deviations were measured. Chi square, t, and Fisher's exact tests were applied.

RESULTS

Correct drug choice, dose, dosage form, route of administration were significantly higher in the clinic adopting IMCI {clinic B} (89.3%, 87.3%, 91.3%, and 91.3%, respectively) than in the clinic not adopting it {clinic A} (78% each). Non pharmacological remedies prescribed were significantly higher in clinic B than A (64.7% vs 4.6%). Average no of drugs/ encounter was lower in clinic B than A (0.93 ± 0.2 vs 1.37 ± 0.6) and the difference between clinics was statistically significant. Difference between clinics regarding percentages of drugs prescribed by generic name, antibiotics prescribed, drugs prescribed from essential drug list, and drugs prescribed out of stock was significant.

CONCLUSION

Adopting IMCI strategy improved prescribing performance and treatment regimen.

Continuing education meetings and workshops: effects on professional practice and health care outcomes

BACKGROUND

Educational meetings are widely used for continuing medical education. Previous reviews found that interactive workshops resulted in moderately large improvements in professional practice, whereas didactic sessions did not.

OBJECTIVES

To assess the effects of educational meetings on professional practice and healthcare outcomes.

SEARCH STRATEGY

We updated previous searches by searching the Cochrane Effective Practice and Organisation of Care Group Trials Register and pending file, from 1999 to March 2006.

SELECTION CRITERIA

Randomised controlled trials of educational meetings that reported an objective measure of professional practice or healthcare outcomes.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted data and assessed study quality. Studies with a low or moderate risk of bias and that reported baseline data were included in the primary analysis. They were weighted according to the number of health professionals participating. For each comparison, we calculated the risk difference (RD) for dichotomous outcomes, adjusted for baseline compliance; and for continuous outcomes the percentage change relative to the control group average after the intervention, adjusted for baseline performance. Professional and patient outcomes were analysed separately. We considered 10 factors to explain heterogeneity of effect estimates using weighted meta-regression supplemented by visual analysis of bubble and box plots.

MAIN RESULTS

In updating the review, 49 new studies were identified for inclusion. A total of 81 trials involving more than 11,000 health professionals are now included in the review. Based on 30 trials (36 comparisons), the median adjusted RD in compliance with desired practice was 6% (interquartile range 1.8 to 15.9) when any intervention in which educational meetings were a component was compared to no intervention. Educational meetings alone had similar effects (median adjusted RD 6%, interquartile range 2.9 to 15.3; based on 21 comparisons in 19 trials). For continuous outcomes the median adjusted percentage change relative to control was 10% (interquartile range 8 to 32%; 5 trials). For patient outcomes the median adjusted RD in achievement of treatment goals was 3.0 (interquartile range 0.1 to 4.0; 5 trials). Based on univariate meta-regression analyses of the 36 comparisons with dichotomous outcomes for professional practice, higher attendance at the educational meetings was associated with larger adjusted RDs (P < 0.01); mixed interactive and didactic education meetings (median adjusted RD 13.6) were more effective than either didactic meetings (RD 6.9) or interactive meetings (RD 3.0). Educational meetings did not appear to be effective for complex behaviours (adjusted RD -0.3) compared to less complex behaviours; they appeared to be less effective for less serious outcomes (RD 2.9) than for more serious outcomes.

AUTHORS' CONCLUSIONS

Educational meetings alone or combined with other interventions, can improve professional practice and healthcare outcomes for the patients. The effect is most likely to be small and similar to other types of continuing medical education, such as audit and feedback, and educational outreach visits. Strategies to increase attendance at educational meetings, using mixed interactive and didactic formats, and focusing on outcomes that are likely to be perceived as serious may increase the effectiveness of educational meetings. Educational meetings alone are not likely to be effective for changing complex behaviours.

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.

Strategies for improving the quality of health care in maternal and child health in low- and middle-income countries: an overview of systematic reviews

There are many systematic reviews of continuing education programmes and educational strategies for quality improvement in health care. Most of the reviewed studies are one-off evaluations rather than impact evaluations with long-term follow-up. There are few systematic reviews of organisational, financial and regulatory interventions, and few high-quality studies. These interventions are probably as or more important than educational strategies, although they are less well evaluated. Few studies have been undertaken in low- and middle-income countries (LMIC) or that address maternal and child health (MCH). Thus, the results of the available studies and reviews need to be interpreted cautiously when applied to LMIC. Interactive workshops, reminders and multifaceted interventions can improve professional practice, and they generally have moderate effects. Educational outreach visits consistently improve prescribing but have variable effects on other behaviours. Audit and feedback interventions have variable effects on professional practice, but most often these are small to moderate effects. Mass-media and patient-mediated interventions may change professional practice. Multifaceted interventions that combine several quality-improvement strategies are also effective but may not be more so than single interventions. While all of these strategies are applicable to MCH in LMIC, the applicability of the results to rural settings, in particular, may be limited. Use of these strategies could exacerbate inequalities, and this should be taken into consideration when planning implementation. Scaling up and sustainability may be difficult to achieve in LMIC contexts and need careful consideration. The use of financial interventions has not been well studied; financial incentives and disincentives may be difficult to use effectively and efficiently, although their impact on practice needs to be considered. Organisational interventions are likely to be important, given that there are often underlying organisational or system problems. Regulatory interventions have not been well evaluated, but may sometimes be both inexpensive and effective. There are no 'magic bullets' or simple solutions for ensuring the quality of health care services. Interventions should be selected or tailored to address the underlying reasons for a failure to deliver effective services. Decision-makers should select the most appropriate interventions for specific problems. This requires a governance structure that clearly assigns responsibility for quality-improvement activities, priority setting, selection and design of interventions, and evaluation.

Characteristics of nurse practitioner curricula in the United States related to antimicrobial prescribing and resistance

PURPOSE

The purpose of this study was to examine current nurse practitioner (NP) curricula in the United States with regard to antibiotics and antimicrobial resistance and assess the need for a web-based module for instruction on antimicrobial resistance and appropriate prescribing of antibiotics.

DATA SOURCES

A 22-item, anonymous, self-administered, web-based survey was sent to 312 NP programs; 149 (48%) responded. Survey items included questions related to NP specialties offered, program accreditation, format of pharmacology course(s), lecture hours related to antimicrobial therapy, and whether the participant would use a Web-based module to teach NP students about antimicrobial resistance, if one were available.

CONCLUSIONS

Most NP programs (99.3%) required a pharmacology course, and 95% had lectures dedicated to antimicrobial therapy. Half of the programs (53.5%) devoted >or=4 lecture hours to antimicrobial therapy in the pharmacology course, and most (84.8%) reported covering antimicrobial therapy in nonpharmacology courses as well. Approximately half of the programs (45.3%) reported <4 h of lecture on antimicrobial therapy in nonpharmacology courses. Many programs (51.9%) did not offer a microbiology course; 39.2% required microbiology as a prerequisite. Most respondents (86.7%) were familiar with the Centers for Disease Control and Prevention antimicrobial resistance program, and 92.6% reported that they would use an electronic module regarding resistance.

IMPLICATIONS FOR PRACTICE

NP curricula generally include <10 h of content on antimicrobial therapy. An electronic module regarding antimicrobial resistance is likely to be a useful and relevant adjunct to current curricula.

A meta-analysis of continuing medical education effectiveness

INTRODUCTION

We undertook a meta-analysis of the Continuing Medical Education (CME) outcome literature to examine the effect of moderator variables on physician knowledge, performance, and patient outcomes.

METHODS

A literature search of MEDLINE and ERIC was conducted for randomized controlled trials and experimental design studies of CME outcomes in which physicians were a major group. CME moderator variables included the types of intervention, the types and number of participants, time, and the number of intervention sessions held over time.

RESULTS

Thirty-one studies met the eligibility criteria, generating 61 interventions. The overall sample-size weighted effect size for all 61 interventions was r = 0.28 (0.18). The analysis of CME moderator variables showed that active and mixed methods had medium effect sizes (r = 0.33 [0.33], r = 0.33 [0.26], respectively), and passive methods had a small effect size (r = 0.20 [0.16], confidence interval 0.15, 0.26). There was a positive correlation between the effect size and the length of the interventions (r = 0.33) and between multiple interventions over time (r = 0.36). There was a negative correlation between the effect size and programs that involved multiple disciplines (r = -0.18) and the number of participants (r = -0.13). The correlation between the effect size and the length of time for outcome assessment was negative (r = -0.31).

DISCUSSION

The meta-analysis suggests that the effect size of CME on physician knowledge is a medium one; however, the effect size is small for physician performance and patient outcome. The examination of moderator variables shows there is a larger effect size when the interventions are interactive, use multiple methods, and are designed for a small group of physicians from a single discipline.

Changing antibiotics prescribing practices in health centers of Khartoum State, Sudan

OBJECTIVE

A major problem with inappropriate use of antibiotics is the emergence of resistance. Thus, cost-effective interventional strategies are required to improve their use. This study aimed to evaluate the effect of multifaceted interventions on prescribing practices of antibiotics in health centers of Khartoum State, Sudan.

METHODS

Twenty health centers were randomly assigned to receive: (1) no intervention; (2) audit and feedback; (3) audit and feedback + seminar; or (4) audit and feedback + academic detailing. A total of 1,800 patient encounters, 30 from each health center, were randomly collected. The total number of encounters with antibiotics prescribed were determined in each health center and they were evaluated with regard to antibiotic choice, dose and duration of therapy before the study and at 1 and 3 months post-intervention.

RESULTS

In comparison to the control group, the prescriber targeted interventions involving audit and feedback, together with academic detailing (4), reduced the mean number of encounters with an antibiotic prescribed by 6.3 and 7.7 (p<0.001) at 1 and 3 months post-intervention, respectively. In addition, the mean number of encounters with an inappropriate antibiotic with respect to diagnosis, doses and/ or duration of therapy was reduced by 5.3 and 5.9 (p<0.001) at 1 and 3 months post-intervention, respectively. For audit and feedback together with seminars (3) and for audit and feedback alone (2), the corresponding reductions were 5.3, 7.1, 4.4 and 5.1 (p<0.001) and 1.4, 2.8, 1.8 and 1.9 (p>0.05), respectively.

CONCLUSION

Inappropriate prescribing patterns of antibiotics in health centers of Khartoum State, Sudan, are alarmingly high. Multifaceted interventions involving audit and feedback combined with either academic detailing or seminars appear more effective in changing prescribing practices of antibiotics than audit and feedback alone.

Changing antibiotics prescribing practices in health centers of Khartoum State, Sudan

OBJECTIVE

A major problem with inappropriate use of antibiotics is the emergence of resistance. Thus, cost-effective interventional strategies are required to improve their use. This study aimed to evaluate the effect of multifaceted interventions on prescribing practices of antibiotics in health centers of Khartoum State, Sudan.

METHODS

Twenty health centers were randomly assigned to receive: (1) no intervention; (2) audit and feedback; (3) audit and feedback + seminar; or (4) audit and feedback + academic detailing. A total of 1,800 patient encounters, 30 from each health center, were randomly collected. The total number of encounters with antibiotics prescribed were determined in each health center and they were evaluated with regard to antibiotic choice, dose and duration of therapy before the study and at 1 and 3 months post-intervention.

RESULTS

In comparison to the control group, the prescriber targeted interventions involving audit and feedback, together with academic detailing (4), reduced the mean number of encounters with an antibiotic prescribed by 6.3 and 7.7 (p<0.001) at 1 and 3 months post-intervention, respectively.

CONCLUSION

Inappropriate prescribing patterns of antibiotics in health centers of Khartoum State, Sudan, are alarmingly high. Multifaceted interventions involving audit and feedback combined with either academic detailing or seminars appear more effective in changing prescribing practices of antibiotics than audit and feedback alone.

Knowledge translation in developing countries

There is increasing evidence that the application of knowledge in developing countries is failing. One reason is the woeful shortage of health workers, but as this is redressed, it is also crucial that we have an evidence base of what works to minimize the "know-do gap." The World Health Organization and other international organizations are actively building momentum to promote research to determine effective strategies for knowledge translation (KT). At this time, the evidence base for the effectiveness of those strategies is not definitive in developed countries and is relatively sparse in developing countries. It appears, however, that the effectiveness of these strategies is highly variable and dependent on the setting, and success hinges on whether the strategies have been tailored. A useful framework to provide direction for tailoring interventions is the Ottawa Model of Research Use (OMRU). Underlying OMRU is the principle that success rests with tailoring KT strategies to the salient barriers and supports found within the setting. The model recommends that barriers and supports found in the practice environment or as characteristics of potential adopters and the evidence-based innovation or research evidence be assessed and then the KT strategy tailored and executed. The model also recommends that whether the research has been applied and has resulted in improved health outcomes should be measured. Studies in developing countries, although few, illustrate that the OMRU approach may be a valid method of tackling the challenges of KT strategies to improve health care in developing countries.

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.

Antimicrobial resistance in developing countries. Part II: strategies for containment

The growing threat from resistant organisms calls for concerted action to prevent the emergence of new resistant strains and the spread of existing ones. Developing countries have experienced unfavourable trends in resistance-as detailed in part I, published last month--and implementation of many of the containment strategies recommended by WHO is complicated by universal, as well as developing country-specific, factors. The control of selective pressure for resistance could potentially be addressed through educational and other interventions for orthodox and unorthodox prescribers, distributors, and consumers of antimicrobials. At national levels, the implementation of drug use strategies--eg, combination therapy or cycling--may prove useful to lengthen the lifespan of existing and future agents. Programmes such as the Integrated Management of Childhood Illnesses (IMCI) and directly observed short-course therapy (DOTS) for tuberculosis are prescriber-focused and patient-focused, respectively, and have both been shown to positively influence factors that contribute to the selective pressure that affects resistance. The institution of interventions to prevent the transmission of infectious diseases could also lead to beneficial effects on the prevalence of resistance, as has vaccination against Haemophilus influenzae type B and Streptococcus pneumoniae. There has been an upsurge in the number of organisations and programmes that directly address issues of resistance, and collaboration could be one way to stem the dire trend. Additional factors such as unregulated drug availability, inadequate antimicrobial drug quality assurance, inadequate surveillance, and cultures of antimicrobial abuse must be addressed to permit a holistic strategy for resistance control.

Procalcitonin-guided antibiotic use versus a standard approach for acute respiratory tract infections in primary care: study protocol for a randomised controlled trial and baseline characteristics of participating general practitioners [ISRCTN73182671]

BACKGROUND

Acute respiratory tract infections (ARTI) are among the most frequent reasons for consultations in primary care. Although predominantly viral in origin, ARTI often lead to the prescription of antibiotics for ambulatory patients, mainly because it is difficult to distinguish between viral and bacterial infections. Unnecessary antibiotic use, however, is associated with increased drug expenditure, side effects and antibiotic resistance. A novel approach is to guide antibiotic therapy by procalcitonin (ProCT), since serum levels of ProCT are elevated in bacterial infections but remain lower in viral infections and inflammatory diseases. The aim of this trial is to compare a ProCT-guided antibiotic therapy with a standard approach based on evidence-based guidelines for patients with ARTI in primary care.

METHODS/DESIGN

This is a randomised controlled trial in primary care with an open intervention. Adult patients judged by their general practitioner (GP) to need antibiotics for ARTI are randomised in equal numbers either to standard antibiotic therapy or to ProCT-guided antibiotic therapy. Patients are followed-up after 1 week by their GP and after 2 and 4 weeks by phone interviews carried out by medical students blinded to the goal of the trial. Exclusion criteria for patients are antibiotic use in the previous 28 days, psychiatric disorders or inability to give written informed consent, not being fluent in German, severe immunosuppression, intravenous drug use, cystic fibrosis, active tuberculosis, or need for immediate hospitalisation. The primary endpoint is days with restrictions from ARTI within 14 days after randomisation. Secondary outcomes are antibiotic use in terms of antibiotic prescription rate and duration of antibiotic treatment in days, days off work and days with side-effects from medication within 14 days, and relapse rate from the infection within 28 days after randomisation.

DISCUSSION

We aim to include 600 patients from 50 general practices in the Northwest of Switzerland. Data from the registry of the Swiss Medical Association suggests that our recruited GPs are representative of all eligible GPs with respect to age, proportion of female physicians, specialisation, years of postgraduate training and years in private practice.

Getting evidence into practice: what works in developing countries?

PURPOSE

We summarize and comment on the available literature on the effectiveness of interventions designed to change professional behaviour in order to bring evidence into practice in developing countries.

DATA SOURCES

We used a strategy adapted from the Effective Practice & Organization Care (EPOC) Cochrane group.

STUDY SELECTION

Forty-four studies met pre-defined selection criteria. Controlled and uncontrolled trials of interventions were included. Studies measured either professional compliance with agreed standards or patients' clinical outcomes. Data extraction. Data were extracted using a pre-defined extraction tool and studies were appraised accordingly.

RESULTS OF DATA SYNTHESIS

Data were synthesized and categorized according to different types of intervention. Audit and feedback was found to be effective, at least in the short term, when combined with other approaches. Similarly, educational interventions were more effective when designed to address local educational needs and organizational barriers. We found insufficient evidence to assess the effectiveness of educational outreach, local opinion leaders, use of mass media, and reminders. Educational materials alone are unlikely to influence change. However, the majority of studies had weak designs and failed to exclude possible biases.

CONCLUSION

Current evidence for the effectiveness of interventions to change health professionals' behaviour in developing countries is either scanty or flawed due to poorly designed research. Given the recent drive to improve quality of care, this should be a priority area for researchers and international agencies supporting health systems development in developing countries. This review provides an insight into some of the methodological issues that interested researchers may face.

Controlled Trials to Improve Antibiotic Utilization: A Systematic Review of Experience, 1984–2004

STUDY OBJECTIVES

To review the effectiveness of interventions designed to improve antibiotic prescribing patterns in clinical practice and to draw inferences about the most practical methods for optimizing antibiotic utilization in hospital and ambulatory settings.

METHODS

A literature search using online databases for the years 1975-2004 identified controlled trials of strategies for improving antibiotic utilization. Due to variation in study settings and design, quantitative meta-analysis was not feasible. Therefore, a qualitative literature review was conducted.

RESULTS

Forty-one controlled trials met the search criteria. Interventions consisted of education, peer review and feedback, physician participation, rewards and penalties, administrative methods, and combined approaches. Social marketing directed at patients and prescribers was effective in varying contexts, as was implementation of practice guidelines. Authorization systems with structured order entry, formulary restriction, and mandatory consultation were also effective. Peer review and feedback were more effective when combined with dissemination of relevant information or social marketing than when used alone.

CONCLUSIONS

Several practices were effective in improving antibiotic utilization: social marketing, practice guidelines, authorization systems, and peer review and feedback. Online systems providing clinical information, structured order entry, and decision support may be the most promising approach. Further studies, including economic analyses, are needed to confirm or refute this hypothesis.

Clinical predictors of bloodstream infections and mortality in hospitalized Malawian children

BACKGROUND

In sub-Saharan Africa, bloodstream infections (BSI) are a major cause of pediatric mortality. Because of limited resources and facilities in these developing countries, treatment often must be based solely on clinical observations and patient history and includes the use of broad spectrum antimicrobials, a factor in the emergence of antibiotic resistance.

METHODS

During July 28 through August 18, 1998 we analyzed clinical, epidemiologic and microbiologic data from a cohort of 225 hospitalized children in Malawi, Africa, to determine clinical indices associated with the presence/absence of BSI and/or mortality for use in settings with minimal microbiologic laboratory and intensive care facilities.

RESULTS

BSI (n = 35 children) were associated with malnutrition, chronic cough, lethargy by history, lethargy on examination and oral thrush; 92% of children without these symptoms were BSI-negative. Mortality (21 of 173 children with known mortality status) was associated with malnutrition, lethargy on examination, prior receipt of antimalarials and acute decreased feeding. Of those with > or =2 of these indices 69% died; of those with <2 of the indices 94% survived. Infection with human immunodeficiency virus was not significantly related to either BSI or mortality status.

CONCLUSIONS

Malnutrition, but not HIV, was strongly related to both BSI and mortality. Assessment of these BSI and mortality indices at hospital admission provides rapid, cost-free indication of which children are most/least in need of empiric antimicrobial therapy or intensive observation, thereby maximizing appropriate use of antimicrobials and limited facilities while minimizing inappropriate antimicrobial usage.

Effectiveness of feedback for improving case management of malaria, diarrhoea and pneumonia--a randomized controlled trial at provincial hospitals in Lao PDR

BACKGROUND

Standard Treatment Guidelines were introduced to all prescribers at provincial hospitals in Lao PDR and treatment indicators were developed within the National Drug Policy programme to monitor compliance.

OBJECTIVES

To evaluate the effects of an educational intervention to improve treatment practices of malaria, diarrhoea and pneumonia.

METHODS

Randomized controlled trial with prescribers at 24 departments at eight provincial hospitals, matched into four pairs. The three departments of internal medicine, paediatrics and out-patients in each pair were randomized into intervention or control group. The 6-month intervention was conducted by members of the Drug and Therapeutics Committees, and comprised monthly audit sessions in the form of outcome feedback using indicator scores on recorded treatment of malaria, diarrhoea and pneumonia. We measured treatment indicator scores 6 months after the end of the intervention compared with baseline.

RESULTS

The aggregated mean scores for all diseases, and for malaria and diarrhoea, improved significantly. For pneumonia, improvement was seen in both the intervention and control groups. Record keeping was improved for all three diseases. For malaria, there were improvements in recording patients' history, and in frequency of microscope testing; for diarrhoea, regarding weight measurements, palpation of the fontanel for children under 2 years, and reduction of irrational use of anti-diarrhoeals and antibiotics; for pneumonia, in recording respiratory count, and reducing irrational use of anti-histamines and anti-cough medications.

CONCLUSIONS

Audit-feedback systems to improve quality of care are feasible and effective also in hospital settings in low-income countries.

Factors influencing private health providers' technical quality of care for acute respiratory infections among under-five children in rural West Bengal, India

In many developing countries, private health practitioners provide a significant portion of curative care for diseases which are of public health importance. Currently, health sector reform efforts in these countries are fostering increased participation of private providers in the delivery of health services, including those of public health importance. Guaranteeing good technical quality of care is critical to the process. However, little is known about private providers' technical quality of care (disease management practices) and the factors influencing these services. The purpose of this study was to contribute information on this topic. The study was conducted among private providers in rural West Bengal, India and focused on providers' disease management practices for acute respiratory infections (ARI) among under-five children. World Health Organization (WHO) guidelines for ARI case management were used as the expected standard of care. Observations of patient-provider encounters and interviews with the providers and mothers were the main sources of data. The study found that private health providers in rural West Bengal have inadequate technical quality of care. The problem was related both to low levels of performance (limited potential) and inconsistency in performance (within-provider variation). Limited potential for good technical quality for ARI among the providers was related to lack of knowledge (technical incompetence). One of the important factors influencing within-provider variation was patient load. Since rural private providers operate on a fee-for-service payment system, there are incentives related to seeing many patients. The study concluded that to bring about sustainable improvements in private providers' ARI disease management practices, training programs and interventions that improved compliance were necessary.

Improving private pharmacy practice: a multi-intervention experiment in Hanoi, Vietnam

The objective of this study was to assess the effects of a multicomponent intervention on private pharmacy practice. From 641 private pharmacies in Hanoi, 68 pharmacies were randomly selected and matched into 34 pairs. Each pair consisted of a control and an intervention pharmacy. Three interventions were applied sequentially: Regulatory enforcement, Education, and Peer influence. Four tracer conditions were selected: uncomplicated acute respiratory infection (ARI), sexually transmitted disease (STD), requesting the prescription-only drugs prednisolone, and a short course of cefalexin. Practice was assessed through the Simulated Client Method (SCM). The intervention pharmacies improved significantly compared to the control pharmacies (P <.05) in all tracer conditions. For ARI, antibiotic dispensing decreased (P <.02) and questions regarding breathing increased (P <.01). For STD, advice to go to the doctor and dispensing the correct syndromic treatment increased (P <.01). Dispensing of prednisolone and cefalexin decreased (P <.01) and prescription requests increased (P <.01). Our conclusion is that it is possible to improve private pharmacy practice with a multicomponent intervention.

Effectiveness of educational interventions on the improvement of drug prescription in primary care: a critical literature review

This paper is a critical review of studies of educational programmes designed to improve prescription practices in ambulatory care. Scientific articles were selected from the following bibliographical indices: MEDLINE, IME, ICYT and ERIC. The searches covered the time period between 1988 and 1997. The search criteria included: primary-care, educat*, prescription* and other related keywords. The inclusion criteria were studies describing educational strategies aimed at general practitioners working in ambulatory settings. The study outcome was change in prescribing behaviour of physicians through prescribing indicators. The following data were extracted: study design, target drugs, type of intervention, follow-up period of the prescription trends, type of data analysis, type of statistical analysis and reported results. We found 3233 articles that met the search criteria. Of these, 51 met the inclusion criteria and 43 studied the efficacy/effectiveness of one or various interventions as compared to no intervention. Among seven studies evaluating active strategies, four reported positive results (57%), as opposed to three of the eight studies assessing passive strategies (38%). Among the 28 studies that tested reinforced active strategies, 16 reported positive results for all variables (57%). Eight studies were classified as a high degree of evidence (16%). We concluded that the results of our review suggest that the more personalized, the more effective the strategies are. We observe that combining active and passive strategies results in a decrease of the failure rate. Finally, better studies are still needed to enhance the efficacy and efficiency of prescribing practices.

One-to-one versus group sessions to improve prescription in primary care: a pragmatic randomized controlled trial

OBJECTIVES

The objective of the study was to evaluate the effectiveness of 2 educational strategies aimed at improving prescribing standards in primary care.

METHODS

A pragmatic controlled trial was designed; the study population included general and family practitioners in Galicia (northwestern Spain) divided into 3 study groups: a one-to-one education group (n = 98), a by-group education group (n = 92), and a control group (n = 405). The educational intervention included explicit recommendations for selecting nonsteroidal anti-inflammatory drugs (NSAIDs) for inflammation signs. Some of the subjects were given reminders. Mixed-effect linear models were applied to data analysis. Analyses were done by intention-to-treat. The dependent variable is a rate with a numerator that is the number of prescribed units of the NSAIDs recommended during intervention; the denominator is the total number of prescribed units of the NSAID total.

RESULTS

One-to-one education obtained an average prescribing behavior improvement of 6.5% (P < 0.001) in the 9 months after intervention. In the education group, the average improvement was 2.4% (P < 0.05) for the same period. Statistically significant differences were observed between the group intervention and one-to-one groups. The reminder increased significantly the effectiveness of the one-to-one intervention.

CONCLUSIONS

A single, short educational session to primary care doctors can improve their prescribing standards during long periods of > or = 9 months. Of the 2 strategies followed in the trial, one-to-one education has shown to be the most effective. Results also show that the effectiveness of these interventions increases when presented together with written material.

Continuing education meetings and workshops: effects on professional practice and health care outcomes

BACKGROUND

Educational meetings and printed educational materials are the two most common types of continuing education for health professionals. An important aim of continuing education is to improve professional practice so that patients can receive improved health care.

OBJECTIVES

To assess the effects of educational meetings on professional practice and health care outcomes.

SEARCH STRATEGY

We searched the Cochrane Effective Practice and Organisation of Care Group specialised register, MEDLINE (from 1966), the Research and Development Resource Base in Continuing Medical Education in January 1999 and reference lists of articles.

SELECTION CRITERIA

Randomised trials or well designed quasi-experimental studies examining the effect of continuing education meetings (including lectures, workshops, and courses) on the clinical practice of health professionals or health care outcomes.

DATA COLLECTION AND ANALYSIS

Two reviewers independently applied inclusion criteria, assessed the quality of each study, and extracted study data. We attempted to collect missing data from investigators. We conducted both qualitative and quantitative analyses.

MAIN RESULTS

Thirty-two studies were included with a total of 36 comparisons. The studies involved from 13 to 411 health professionals (total N= 2995) and were judged to be of moderate or high quality, although methods were generally poorly reported. There was substantial variation in the complexity of the targeted behaviours, baseline compliance, the characteristics of the interventions and the results. The heterogeneity of the results was best explained by differences in the interventions. For 10 comparisons of interactive workshops, there were moderate or moderately large effects in six (all of which were statistically significant) and small effects in four (one of which was statistically significant). For interventions that combined workshops and didactic presentations, there were moderate or moderately large effects in 12 comparisons (eleven of which were statistically significant) and small effects in seven comparisons (one of which was statistically significant). In seven comparisons of didactic presentations, there were no statistically significant effects, with the exception of one out of four outcome measures in one study.

REVIEWER'S CONCLUSIONS

Interactive workshops can result in moderately large changes in professional practice. Didactic sessions alone are unlikely to change professional practice.

Socioeconomic and behavioral factors leading to acquired bacterial resistance to antibiotics in developing countries

In developing countries, acquired bacterial resistance to antimicrobial agents is common in isolates from healthy persons and from persons with community-acquired infections. Complex socioeconomic and behavioral factors associated with antibiotic resistance, particularly regarding diarrheal and respiratory pathogens, in developing tropical countries, include misuse of antibiotics by health professionals, unskilled practitioners, and laypersons; poor drug quality; unhygienic conditions accounting for spread of resistant bacteria; and inadequate surveillance.
