Local opinion leaders: effects on professional practice and health care outcomes

The timing of elective caesarean delivery between 2000 and 2009 in England

BACKGROUND

In 2004, the National Institute for Clinical Excellence (NICE) recommended that an elective caesarean section for an uncomplicated pregnancy should not be carried out before 39 completed weeks due to increased risk of respiratory morbidity in newborns. We describe the trends and variation across 63 English NHS trusts in the timing of elective caesarean section (CS) for low-risk singleton deliveries.

METHODS

We identified elective CS deliveries between 1st April 2000 and 28th February 2009 in English NHS trusts using the Hospital Episode Statistics. We selected women with uncomplicated pregnancies who had an elective CS delivery after 34 completed weeks of gestation, and analysed the trends and the trust-level variation in the timing of elective CS. The impact of the NICE guidance on the monthly rate of elective CS deliveries performed after 39 weeks was estimated using an interrupted time-series design with autoregressive integrated moving average (ARIMA).

RESULTS

There were 118,456 elective CS deliveries at the 63 NHS trusts. The overall proportion of elective CS deliveries done after 39 completed weeks steadily increased from 39% in 2000/01 to 63% in 2008/09. The proportions rose from 43% to 67% for women with breech presentation and from 35% to 62% for women with a previous CS. There was significant variation across NHS trusts in each year; in 2008/09, with the proportions of elective CS done after 39 weeks ranging from 28% to 89% (Inter-quartile range limits: 54% to 72%). We found a small but statistically significant increase in the proportion immediately after the publication of the NICE guidance, but its rate of growth rate declined slightly thereafter.

CONCLUSIONS

NHS trusts in our study have responded to the new evidence on the benefits of delaying elective CS to after 39 weeks gestation. However, substantial differences between NHS trusts remain, which indicates there is room for further improvement. We suggest that maternity services and commissioners adopt the "timing of elective caesarean" as a quality indicator to support clinical practice.

Patient or treatment centre? Where are efforts invested to improve cancer patients' psychosocial outcomes?

The psychosocial outcomes of cancer patients may be influenced by individual-level, social and treatment centre predictors. This paper aimed to examine the extent to which individual, social and treatment centre variables have been examined as predictors or targets of intervention for psychosocial outcomes of cancer patients. Medline was searched to find studies in which the psychological outcomes of cancer patient were primary variables. Papers published in English between 1999 and 2009 that reported primary data relevant to psychosocial outcomes for cancer patients were included, with 20% randomly selected for further coding. Descriptive studies were coded for inclusion of individual, social or treatment centre variables. Intervention studies were coded to determine if the unit of intervention was the individual patient, social unit or treatment centre. After random sampling, 412 publications meeting the inclusion criteria were identified, 169 were descriptive and 243 interventions. Of the descriptive papers 95.0% included individual predictors, and 5.0% social predictors. None of the descriptive papers examined treatment centre variables as predictors of psychosocial outcomes. Similarly, none of the interventions evaluated the effectiveness of treatment centre interventions for improving psychosocial outcomes. Potential reasons for the overwhelming dominance of individual predictors and individual-focused interventions in psychosocial literature are discussed.

Case-based training of evidence-based clinical practice in primary care and decreased mortality in patients with coronary heart disease

PURPOSE

We investigated the 10-year mortality rates in a trial that tested a case-based intervention in primary care aimed at reducing the gap between evidence-based goals and clinical practice in patients with coronary heart disease (CHD).

METHODS

A prospective randomized controlled pragmatic trial was undertaken in a primary care setting. New evidence-based guidelines, with intensified lipid-lowering recommendations in CHD, were mailed to all general practitioners in the region and presented at a lecture in 1995. General practitioners (n = 54) and patients with CHD (n = 88) were assigned according to their primary health care center to 2 balanced groups and randomly allocated to usual care as a control or to an active intervention. General practitioners in the intervention group participated in repeated case-based training during a 2-year period. Patients whose CHD was treated by specialists (n = 167) served as an internal specialist comparison group. Altogether, 255 consecutive patients were included. Cox regression analysis was used to detect any survival benefit of the intervention.

RESULTS

At 10 years, 22% of the patients in the intervention group had died as compared with 44% in the control group (P = .02), with a hazard ratio of 0.45 (95% confidence interval, 0.20-0.95). This difference was mainly due to reduced cardiovascular mortality in the intervention group (P = .01). In addition, the mortality rate of 22% in the intervention group was comparable to the rate of 23% seen in patients treated by a specialist.

CONCLUSIONS

Use of case-based training to implement evidence-based practice in primary care was associated with decreased mortality at 10 years in patients with CHD.

How can we improve guideline use? A conceptual framework of implementability

BACKGROUND

Guidelines continue to be underutilized, and a variety of strategies to improve their use have been suboptimal. Modifying guideline features represents an alternative, but untested way to promote their use. The purpose of this study was to identify and define features that facilitate guideline use, and examine whether and how they are included in current guidelines.

METHODS

A guideline implementability framework was developed by reviewing the implementation science literature. We then examined whether guidelines included these, or additional implementability elements. Data were extracted from publicly available high quality guidelines reflecting primary and institutional care, reviewed independently by two individuals, who through discussion resolved conflicts, then by the research team.

RESULTS

The final implementability framework included 22 elements organized in the domains of adaptability, usability, validity, applicability, communicability, accommodation, implementation, and evaluation. Data were extracted from 20 guidelines on the management of diabetes, hypertension, leg ulcer, and heart failure. Most contained a large volume of graded, narrative evidence, and tables featuring complementary clinical information. Few contained additional features that could improve guideline use. These included alternate versions for different users and purposes, summaries of evidence and recommendations, information to facilitate interaction with and involvement of patients, details of resource implications, and instructions on how to locally promote and monitor guideline use. There were no consistent trends by guideline topic.

CONCLUSIONS

Numerous opportunities were identified by which guidelines could be modified to support various types of decision making by different users. New governance structures may be required to accommodate development of guidelines with these features. Further research is needed to validate the proposed framework of guideline implementability, develop methods for preparing this information, and evaluate how inclusion of this information influences guideline use.

The African Vaccine-Preventable Diseases Network: a vaccine advocacy initiative

Achieving high and equitable childhood immunisation coverage in Africa will not only protect children from disability and premature death, it will also boost productivity, reduce poverty and support the economic growth of the continent. Thus, Africa needs innovative and sustainable vaccine advocacy initiatives. One such initiative is the African Vaccine-Preventable Diseases Network, formed in 2009. This association of immunisation practitioners, vaccinologists, paediatricians, and infectious disease experts provides a platform to advocate for the introduction of newly available vaccines (e.g. 10-valent and 13-valent pneumococcal conjugate and rotavirus vaccines) into the Expanded Programme on Immunisation (EPI) as well as increased and equitable coverage for established EPI vaccines.

Public pharmacovigilance communication: a process calling for evidence-based, objective-driven strategies

As a contribution to the debate on how best to communicate information on the effective and safe use of medicines to patients, healthcare professionals and the general public, this article proposes to distinguish between communication and transparency purposes, and to test a strategic health communication approach. Any organization aiming to improve medicines use could adapt this approach to its remits and legal obligations. The approach includes agreeing measurable communication objectives through shared problem ownership of all concerned parties, evidence-based design and a cyclic process for planning, implementation and evaluation of communication as a public health intervention. The evidence base, which supplements risk assessment for product- and situation-specific communication on safety concerns, would be derived from research into drug utilization, medical decision making and risk perception, as well as from the participation of patients and healthcare professionals. It is crucial to address the practical questions and concerns of medicine users and to find out why unfavourable patterns of medicine use persist, in order to develop behaviour change models for overcoming these obstacles. For this purpose, appropriate models for facilitating the participation of medicine users in the risk management process will need to be explored. Such two-way communication would inform risk assessment as well as the analysis of risk minimization options, allow for agreement upon communication objectives and enable understandable, attractive communication materials to be designed. The communication programme should use mixed media and repetition of messages for long-term success. This would require cooperation within healthcare and medical information systems. An evaluation of the effectiveness of the communication should support the sustainability of the programme and provide lessons for the future. Given its mission, the pharmacovigilance community has the standing and duty to expand its scale of action and take the initiative in advancing risk management through a scientific approach to improving public communication for the safety of patients.

Training family physicians in shared decision making for the use of antibiotics for acute respiratory infections: a pilot clustered randomized controlled trial

BACKGROUND

Experts estimate that the prevalence of antibiotics use exceeds the prevalence of bacterial acute respiratory infections (ARIs).

OBJECTIVE

To develop, adapt and validate DECISION+ and estimate its impact on the decision of family physicians (FPs) and their patients on whether to use antibiotics for ARIs.

DESIGN

Two-arm parallel clustered pilot randomized controlled trial.

SETTING AND PARTICIPANTS

Four family medicine groups were randomized to immediate DECISION+ participation (the experimental group) or delayed DECISION+ participation (the control group). Thirty-three FPs and 459 patients participated.

INTERVENTION

DECISION+ is a multiple-component, continuing professional development program in shared decision making that addresses the use of antibiotics for ARIs.

MAIN OUTCOME MEASURES

Throughout the pilot trial, DECISION+ was adapted in response to participant feedback. After the consultation, patients and FPs independently self-reported the decision (immediate use, delayed use, or no use of antibiotics) and its quality. Agreement between their decisional conflict was assessed. Two weeks later, patients assessed their decisional regret and health status.

RESULTS

Compared to the control group, the experimental group reduced its immediate use of antibiotics (49 vs. 33% absolute difference = 16%; P = 0.08). Decisional conflict agreement was stronger in the experimental group (absolute difference of Pearson's r = 0.26; P = 0.06). Decisional regret and perceptions of the quality of the decision and of health status in the two groups were similar.

DISCUSSION AND CONCLUSIONS

DECISION+ was developed successfully and appears to reduce the use of antibiotics for ARIs without affecting patients' outcomes. A larger trial is needed to confirm this observation.

Data for improvement and clinical excellence: protocol for an audit with feedback intervention in long-term care

Background

There is considerable evidence about the effectiveness of audit coupled with feedback, although few audit with feedback interventions have been conducted in long-term care (LTC) settings to date. In general, the effects have been found to be modest at best, although in settings where there has been little history of audit and feedback, the effects may be greater, at least initially. The primary purpose of the Data for Improvement and Clinical Excellence (DICE) Long-Term Care project is to assess the effects of an audit with feedback intervention delivered monthly over 13 months in four LTC facilities. The research questions we addressed are:

1. What effects do feedback reports have on processes and outcomes over time?

2. How do different provider groups in LTC and home care respond to feedback reports based on data targeted at improving quality of care?

Methods/design

The research team conducting this study comprises researchers and decision makers in continuing care in the province of Alberta, Canada. The intervention consists of monthly feedback reports in nine LTC units in four facilities in Edmonton, Alberta. Data for the feedback reports comes from the Resident Assessment Instrument Minimum Data Set (RAI) version 2.0, a standardized instrument mandated for use in LTC facilities throughout Alberta. Feedback reports consist of one page, front and back, presenting both graphic and textual information. Reports are delivered to all staff working in the four LTC facilities. The primary evaluation uses a controlled interrupted time series design both adjusted and unadjusted for covariates. The concurrent process evaluation uses observation and self-report to assess uptake of the feedback reports. Following the project phase described in this protocol, a similar intervention will be conducted in home care settings in Alberta. Depending on project findings, if they are judged useful by decision makers participating in this research team, we plan dissemination and spread of the feedback report approach throughout Alberta.

Influence of training in the use and generation of evidence on episiotomy practice and perineal trauma

OBJECTIVE

To examine episiotomy practices before and after a multi-component intervention designed to support the use and generation of research evidence in maternal and neonatal health care.

METHODS

Set in 9 centers across 4 Southeast Asian countries, a retrospective survey was performed for 12 recommended pregnancy/childbirth practices and 13 outcomes of women in each center before and after intervention. Qualitative interviews were conducted to assess staff awareness and experience in evidence-based practice.

RESULTS

There were significant decreases in the rate of episiotomy, from 64.1% to 60.1% (risk difference [RD] -4.0; 95% confidence interval [CI], -5.8 to -2.2) for all women and from 92.2% to 80.7% (RD -11.5; 95% CI, -13.4 to -9.6) for nulliparous women. Severe trauma decreased from 3.9% to 1.9% (RD -2.0; 95% CI, -2.7 to -1.4) for all women and from 6.7% to 3.0% (RD -3.7; 95% CI, -4.9 to -2.5) for nulliparous women. The frequency of intact perineum increased from 12.4% to 15.6% (RD 3.2; 95% CI, 1.9-4.6) for all women and from 1.7% to 8.0% (RD 6.3; 95% CI, 5.0-7.5) for nulliparous women.

CONCLUSION

An intervention based on understanding and using the best available evidence can result in significant improvements in care and health outcomes.

The impact of social networks on knowledge transfer in long-term care facilities: Protocol for a study

BACKGROUND

Social networks are theorized as significant influences in the innovation adoption and behavior change processes. Our understanding of how social networks operate within healthcare settings is limited. As a result, our ability to design optimal interventions that employ social networks as a method of fostering planned behavior change is also limited. Through this proposed project, we expect to contribute new knowledge about factors influencing uptake of knowledge translation interventions.

OBJECTIVES

Our specific aims include: To collect social network data among staff in two long-term care (LTC) facilities; to characterize social networks in these units; and to describe how social networks influence uptake and use of feedback reports.

METHODS AND DESIGN

In this prospective study, we will collect data on social networks in nursing units in two LTC facilities, and use social network analysis techniques to characterize and describe the networks. These data will be combined with data from a funded project to explore the impact of social networks on uptake and use of feedback reports. In this parent study, feedback reports using standardized resident assessment data are distributed on a monthly basis. Surveys are administered to assess report uptake. In the proposed project, we will collect data on social networks, analyzing the data using graphical and quantitative techniques. We will combine the social network data with survey data to assess the influence of social networks on uptake of feedback reports.

DISCUSSION

This study will contribute to understanding mechanisms for knowledge sharing among staff on units to permit more efficient and effective intervention design. A growing number of studies in the social network literature suggest that social networks can be studied not only as influences on knowledge translation, but also as possible mechanisms for fostering knowledge translation. This study will contribute to building theory to design such interventions.

A cluster-randomized trial to improve stroke care in hospitals

OBJECTIVE

We evaluated the effect of performance feedback on acute ischemic stroke care quality in Minnesota hospitals.

METHODS

A cluster-randomized controlled trial design with hospital as the unit of randomization was used. Care quality was defined as adherence to 10 performance measures grouped into acute, in-hospital, and discharge care. Following preintervention data collection, all hospitals received a report on baseline care quality. Additionally, in experimental hospitals, clinical opinion leaders delivered customized feedback to care providers and study personnel worked with hospital administrators to implement changes targeting identified barriers to stroke care. Multilevel models examined experimental vs control, preintervention and postintervention performance changes and secular trends in performance.

RESULTS

Nineteen hospitals were randomized with a total of 1,211 acute ischemic stroke cases preintervention and 1,094 cases postintervention. Secular trends were significant with improvement in both experimental and control hospitals for acute (odds ratio = 2.7, p = 0.007) and in-hospital (odds ratio = 1.5, p < 0.0001) care but not discharge care. There was no significant intervention effect for acute, in-hospital, or discharge care.

CONCLUSION

There was no definite intervention effect: both experimental and control hospitals showed significant secular trends with performance improvement. Our results illustrate the potential fallacy of using historical controls for evaluating quality improvement interventions.

CLASSIFICATION OF EVIDENCE

This study provides Class II evidence that informing hospital leaders of compliance with ischemic stroke quality indicators followed by a structured quality improvement intervention did not significantly improve compliance more than informing hospital leaders of compliance with stroke quality indicators without a quality improvement intervention.

Service organisation for the secondary prevention of ischaemic heart disease in primary care

BACKGROUND

Ischaemic heart disease (IHD) is a major cause of mortality and morbidity and its prevalence is set to increase. Secondary prevention aims to prevent subsequent acute events in people with established IHD. While the benefits of individual medical and lifestyle interventions is established, the effectiveness of interventions which seek to improve the way secondary preventive care is delivered in primary care or community settings is less so.

OBJECTIVES

To assess the effectiveness of service organisation interventions, identifying which types and elements of service change are associated with most improvement in clinician and patient adherence to secondary prevention recommendations relating to risk factor levels and monitoring (blood pressure, cholesterol and lifestyle factors such as diet, exercise, smoking and obesity) and appropriate prophylactic medication.

SEARCH STRATEGY

We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2007, Issue 4), MEDLINE (1966 to Feb 2008), EMBASE (1980 to Feb 2008), and CINAHL (1981 to Feb 2008). Bibliographies were checked. No language restrictions were applied.

SELECTION CRITERIA

Randomised or quasi-randomised controlled trials of service organisation interventions in primary care or community settings in populations with established IHD.

DATA COLLECTION AND ANALYSIS

Analyses were conducted according to Cochrane recommendations and Odds Ratios (with 95% confidence intervals) reported for dichotomous outcomes, mean differences (with 95% CIs) for continuous outcomes.

MAIN RESULTS

Eleven studies involving 12,074 people with IHD were included. Increased proportions of patients with total cholesterol levels within recommended levels at 12 months, OR 1.90 (1.04 to 3.48), were associated with interventions that included regular planned appointments, patient education and structured monitoring of medication and risk factors, but significant heterogeneity was apparent. Results relating to blood pressure within target levels bordered on statistical significance. There were no significant effects of interventions on mean blood pressure or cholesterol levels, prescribing, smoking status or body mass index. Few data were available on the effect on diet. There was some suggestion of a "ceiling effect" whereby interventions have a diminishing beneficial effect once certain levels of risk factor management are reached.

AUTHORS' CONCLUSIONS

There is weak evidence that regular planned recall of patients for appointments, structured monitoring of risk factors and prescribing, and education for patients can be effective in increasing the proportions of patients within target levels for cholesterol control and blood pressure. Further research in this area would benefit from greater standardisation of the outcomes measured.

Effect of point-of-care computer reminders on physician behaviour: a systematic review

BACKGROUND

The opportunity to improve care using computer reminders is one of the main incentives for implementing sophisticated clinical information systems. We conducted a systematic review to quantify the expected magnitude of improvements in processes of care from computer reminders delivered to clinicians during their routine activities.

METHODS

We searched the MEDLINE, Embase and CINAHL databases (to July 2008) and scanned the bibliographies of retrieved articles. We included studies in our review if they used a randomized or quasi-randomized design to evaluate improvements in processes or outcomes of care from computer reminders delivered to physicians during routine electronic ordering or charting activities.

RESULTS

Among the 28 trials (reporting 32 comparisons) included in our study, we found that computer reminders improved adherence to processes of care by a median of 4.2% (interquartile range [IQR] 0.8%-18.8%). Using the best outcome from each study, we found that the median improvement was 5.6% (IQR 2.0%-19.2%). A minority of studies reported larger effects; however, no study characteristic or reminder feature significantly predicted the magnitude of effect except in one institution, where a well-developed, "homegrown" clinical information system achieved larger improvements than in all other studies (median 16.8% [IQR 8.7%-26.0%] v. 3.0% [IQR 0.5%-11.5%]; p = 0.04). A trend toward larger improvements was seen for reminders that required users to enter a response (median 12.9% [IQR 2.7%-22.8%] v. 2.7% [IQR 0.6%-5.6%]; p = 0.09).

INTERPRETATION

Computer reminders produced much smaller improvements than those generally expected from the implementation of computerized order entry and electronic medical record systems. Further research is required to identify features of reminder systems consistently associated with clinically worthwhile improvements.

Information exchange networks for chronic illness care in primary care practices: an observational study

Background

Information exchange networks for chronic illness care may influence the uptake of innovations in patient care. Valid and feasible methods are needed to document and analyse information exchange networks in healthcare settings. This observational study aimed to examine the usefulness of methods to study information exchange networks in primary care practices, related to chronic heart failure, diabetes and chronic obstructive pulmonary disease.

Methods

The study was linked to a quality improvement project in the Netherlands. All health professionals in the practices were asked to complete a short questionnaire that documented their information exchange relations. Feasibility was determined in terms of response rates and reliability in terms of reciprocity of reports of receiving and providing information. For each practice, a number of network characteristics were derived for each of the chronic conditions.

Results

Ten of the 21 practices in the quality improvement project agreed to participate in this network study. The response rates were high in all but one of the participating practices. For the analysis, we used data from 67 health professionals from eight practices. The agreement between receiving and providing information was, on average, 65.6%. The values for density, centralization, hierarchy, and overlap of the information exchange networks showed substantial variation between the practices as well as between the chronic conditions. The most central individual in the information exchange network could be a nurse or a physician.

Conclusions

Further research is needed to refine the measure of information networks and to test the impact of network characteristics on the uptake of innovations.

Interventions for improving the appropriate use of imaging in people with musculoskeletal conditions

BACKGROUND

Imaging is commonly performed for musculoskeletal conditions. Identifying interventions to improve the appropriate use of imaging for musculoskeletal conditions could potentially result in improved health outcomes for patients and reduced health care costs.

OBJECTIVES

To determine the effects of interventions that aim to improve the appropriate use of imaging for people with musculoskeletal conditions.

SEARCH STRATEGY

We searched the Cochrane Effective Practice and Organisation of Care Group Specialised Register (June 2007), The Cochrane Central Register of Controlled Trials (The Cochrane Library 2007, Issue 2), MEDLINE (January 1966 to June 2007), EMBASE (January 1980 to June 2007) and CINAHL (January 1982 to June 2007). We also searched reference lists of included studies and relevant reviews. We undertook citation searches of all included studies, contacted authors of included studies, and contacted other experts in the field of effective professional practice.

SELECTION CRITERIA

Randomised controlled trials, non-randomised controlled clinical trials and interrupted time-series analyses that evaluated interventions designed to improve the use of imaging for musculoskeletal symptoms.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed risk of bias and extracted data. We contacted study authors for additional information.

MAIN RESULTS

Twenty eight studies met our inclusion criteria. The majority of the studies were for the management of osteoporosis or low back pain, and most evaluated interventions aimed at health professionals. To improve the use of imaging in the management of osteoporosis, the effect of any type of intervention compared to no-intervention controls was modest (absolute improvement in bone mineral density test ordering +10%, IQR 0.0 to +27.7). Patient mediated, reminder, and organisational interventions appeared to have most potential for improving imaging use in osteoporosis. For low back pain studies, the most common intervention evaluated was distribution of educational materials and this showed varying effects. Other interventions in low back pain studies also showed variable effects. For other musculoskeletal conditions, distribution of educational materials, educational meetings and audit and feedback were not shown to be effective for changing imaging ordering behaviour. Across all conditions, increasing the number of intervention components did not increase effect.

AUTHORS' CONCLUSIONS

For improving the use of imaging in osteoporosis, most professional interventions demonstrated benefit, and patient mediated, reminder, and organisational interventions appeared to have most potential for benefit. For low back pain studies interventions showed varying effects. For other musculoskeletal conditions, no firm conclusions can be drawn.

Computerized clinical decision support for prescribing: provision does not guarantee uptake

There is wide variability in the use and adoption of recommendations generated by computerized clinical decision support systems (CDSSs) despite the benefits they may bring to clinical practice. We conducted a systematic review to explore the barriers to, and facilitators of, CDSS uptake by physicians to guide prescribing decisions. We identified 58 studies by searching electronic databases (1990-2007). Factors impacting on CDSS use included: the availability of hardware, technical support and training; integration of the system into workflows; and the relevance and timeliness of the clinical messages. Further, systems that were endorsed by colleagues, minimized perceived threats to professional autonomy, and did not compromise doctor-patient interactions were accepted by users. Despite advances in technology and CDSS sophistication, most factors were consistently reported over time and across ambulatory and institutional settings. Such factors must be addressed when deploying CDSSs so that improvements in uptake, practice and patient outcomes may be achieved.

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.

The effect of continuing professional education on health care outcomes: lessons for dementia care

BACKGROUND

This review presents an overview of the published literature on the effectiveness of continuing professional education (CPE), which includes continuing medical education (CME) of different health care professionals in healthcare settings, for improving patient management and patient outcomes. This review summarizes key articles published on the subject, including those relating to dementia care.

METHODS

A literature search was carried out using the National Library of Medicine's PubMed database, Cochrane database and Eric databases.

RESULTS

Studies on CPE generally provide conflicting evidence on their effectiveness in bringing about a change in professional practices and healthcare outcomes. However interactive, multifaceted interventions, and interventions with repeated inputs appear more effective in bringing about positive changes than traditional non-interactive techniques. There are relatively few studies specifically concerning CPE and dementia care.

CONCLUSION

This review shows that CPE in dementia care needs to be targeted carefully. Much can be learnt from examining education approaches in the wider professional and medical education literature.

Do knowledge infrastructure facilities support evidence-based practice in occupational health? An exploratory study across countries among occupational physicians enrolled on Evidence-Based Medicine courses

Background

Evidence-Based Medicine (EBM) is an important method used by occupational physicians (OPs) to deliver high quality health care. The presence and quality of a knowledge infrastructure is thought to influence the practice of EBM in occupational health care. This study explores the facilities in the knowledge infrastructure being used by OPs in different countries, and their perceived importance for EBM practice.

Methods

Thirty-six OPs from ten countries, planning to attend an EBM course and to a large extent recruited via the European Association of Schools of Occupational Medicine (EASOM), participated in a cross-sectional study.

Results

Research and development institutes, and knowledge products and tools are used by respectively more than 72% and more than 80% of the OPs and they are rated as being important for EBM practice (more than 65 points (range 0–100)). Conventional knowledge access facilities, like traditional libraries, are used often (69%) but are rated as less important (46.8 points (range 0–100)) compared to the use of more novel facilities, like question-and-answer facilities (25%) that are rated as more important (48.9 points (range 0–100)). To solve cases, OPs mostly use non evidence-based sources. However, they regard the evidence-based sources that are not often used, e.g. the Cochrane library, as important enablers for practising EBM. The main barriers are lack of time, payment for full-text articles, language barrier (most texts are in English), and lack of skills and support.

Conclusion

This first exploratory study shows that OPs use many knowledge infrastructure facilities and rate them as being important for their EBM practice. However, they are not used to use evidence-based sources in their practice and face many barriers that are comparable to the barriers physicians face in primary health care.

Development and pilot evaluation of a complex intervention to improve experienced continuity of care in patients with cancer

High experienced continuity of care in patients with cancer is associated with lower needs for care, better quality of life and better psychological outcomes. We developed and evaluated an intervention to improve experienced continuity. The intervention, consisted of (1) a 17-item patient-completed continuity assessment; (2) feedback to clinical nurse specialists and action to address the needs identified. Multidisciplinary team meetings and oncology outpatient clinics were observed, and patients and staff were interviewed. After qualitative work and reliability testing, the intervention was evaluated in a feasibility trial. Sixty-one patients provided data for analysis. No statistically significant differences were found in patients' experienced continuity between the trial arms, but important trends were seen in measures of needs for care in favour of those receiving the intervention. Feeding back findings from the continuity assessment to clinicians reduced patients' needs for care. Our results indicate that an intervention to target patients' experiences of continuity can reduce their subsequent needs for care. However, overcoming barriers to organisational change and addressing some patients' hesitation to report their continuity difficulties must be considered when implementing such an intervention. A phase III trial targeting patients with inadequate experienced continuity of care is recommended.

Multiple factors influence compliance with colorectal cancer staging recommendations: an exploratory study

BACKGROUND

For patients with colorectal cancer (CRC) retrieval by surgeons, and assessment by pathologists of at least 12 lymph nodes (LNs) predicts the need for adjuvant treatment and improved survival. Different interventions (educational presentation, engaging clinical opinion leaders, performance data sent to hospital executives) to improve compliance with this practice had variable results. This exploratory study examined factors hypothesized to have influenced the outcome of those interventions.

METHODS

Semi-structured interviews were conducted with 26 surgeons and pathologists at eleven hospitals. Clinicians were identified by intervention organizers, public licensing body database, and referral from interviewees. An interview guide incorporating open-ended questions was pilot-tested on one surgeon and pathologist. A single investigator conducted all interviews by phone. Transcripts were analyzed independently by two investigators using a grounded approach,ho then compared findings to resolve differences.

RESULTS

Improvements in LN staging practice may have occurred largely due to educational presentations that created awareness, and self-initiated changes undertaken by pathologists. Executives that received performance data may not have shared this with staff, and opinion leaders engaged to promote compliance may not have fulfilled their roles. Barriers to change that are potentially amenable to quality improvement included perceptions about the practice (perceived lack of evidence for the need to examine at least 12 LNs) and associated responsibilities (blaming other profession), technical issues (need for pathology assistants, better clearing solutions and laboratory facilities), and a lack of organizational support for multidisciplinary interaction (little communication between surgeons and pathologists) or quality improvement (no change leaders or capacity for monitoring).

CONCLUSION

Use of an exploratory approach provided an in-depth view of the way that numerous factors amenable to quality improvement influenced the adoption of new CRC LN staging recommendations. Continued interventions targeting physicians and executives, in the absence of a receptive organizational infrastructure, may be fruitless. Individualized rather than regional or punitive performance data, coupled with increased organizational capacity for change may stimulate greater surgical and organizational response to quality improvement. Descriptive or experimental studies are needed to test these hypotheses.

Educational outreach visits: effects on professional practice and health care outcomes

BACKGROUND

Educational outreach visits (EOVs) have been identified as an intervention that may improve the practice of healthcare professionals. This type of face-to-face visit has been referred to as university-based educational detailing, academic detailing, and educational visiting.

OBJECTIVES

To assess the effects of EOVs on health professional practice or patient outcomes.

SEARCH STRATEGY

For this update, we searched the Cochrane EPOC register to March 2007. In the original review, we searched multiple bibliographic databases including MEDLINE and CINAHL.

SELECTION CRITERIA

Randomised trials of EOVs that reported an objective measure of professional performance or healthcare outcomes. An EOV was defined as a personal visit by a trained person to healthcare professionals in their own settings.

DATA COLLECTION AND ANALYSIS

Two reviewers independently extracted data and assessed study quality. We used bubble plots and box plots to visually inspect the data. We conducted both quantitative and qualitative analyses. We used meta-regression to examine potential sources of heterogeneity determined a priori. We hypothesised eight factors to explain variation across effect estimates. In our primary visual and statistical analyses, we included only studies with dichotomous outcomes, with baseline data and with low or moderate risk of bias, in which the intervention included an EOV and was compared to no intervention.

MAIN RESULTS

We included 69 studies involving more than 15,000 health professionals. Twenty-eight studies (34 comparisons) contributed to the calculation of the median and interquartile range for the main comparison. The median adjusted risk difference (RD) in compliance with desired practice was 5.6% (interquartile range 3.0% to 9.0%). The adjusted RDs were highly consistent for prescribing (median 4.8%, interquartile range 3.0% to 6.5% for 17 comparisons), but varied for other types of professional performance (median 6.0%, interquartile range 3.6% to 16.0% for 17 comparisons). Meta-regression was limited by the large number of potential explanatory factors (eight) with only 31 comparisons, and did not provide any compelling explanations for the observed variation in adjusted RDs. There were 18 comparisons with continuous outcomes, with a median adjusted relative improvement of 21% (interquartile range 11% to 41%). There were eight trials (12 comparisons) in which the intervention included an EOV and was compared to another type of intervention, usually audit and feedback. Interventions that included EOVs appeared to be slightly superior to audit and feedback. Only six studies evaluated different types of visits in head-to-head comparisons. When individual visits were compared to group visits (three trials), the results were mixed.

AUTHORS' CONCLUSIONS

EOVs alone or when combined with other interventions have effects on prescribing that are relatively consistent and small, but potentially important. Their effects on other types of professional performance vary from small to modest improvements, and it is not possible from this review to explain that variation.

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.
