Current understanding of implementation methods is limited, and research has focused on changing doctors' behaviors.
                Our aim was to evaluate the impact of audit and feedback and educational outreach in improving nursing practice and patient outcomes.
                Using a factorial design, cluster randomized controlled trial, we evaluated 194 community nurses in 157 family practices and 1078 patients with diagnosis of urinary incontinence (UI) for nurses compliance with evidence-linked review criteria for the assessment and management of UI and impact on psychologic and social well-being and symptoms. In the outreach arms, nurses' self-reported barriers informed development of tailored strategies.
                In comparison with educational materials alone, the implementation methods tested did not improve care at 6 months follow-up. Moderate rates of improvement (10-17% of patients) in performance for the assessment of UI and greater rates of improvement (20-30% of patients) for the management of care were found but effects were similar across arms. Improvement in patient outcomes was more consistently positive for educational outreach than for audit and feedback but differences were not significant. Adjustment for caseload size, severity or duration of UI and patients' age did not alter results.
                Printed educational materials alone may be as effective as audit and feedback and educational outreach in improving nurses' performance and outcomes of care for people with UI. Greater understanding of the underlying processes in improving performance within multidisciplinary teams through further, theory-driven studies with "no intervention" control groups and longer follow-up are needed. Previous studies have shown that Norwegian public health physicians do not systematically and explicitly use scientific evidence in their practice. They work in an environment that does not encourage the integration of this information in decision-making. In this study we investigate whether a theoretically grounded tailored intervention to diffuse evidence-based public health practice increases the physicians' use of research information.
                148 self-selected public health physicians were randomised to an intervention group (n = 73) and a control group (n = 75). The intervention group received a multifaceted intervention while the control group received a letter declaring that they had access to library services. Baseline assessments before the intervention and post-testing immediately at the end of a 1.5-year intervention period were conducted. The intervention was theoretically based and consisted of a workshop in evidence-based public health, a newsletter, access to a specially designed information service, to relevant databases, and to an electronic discussion list. The main outcome measure was behaviour as measured by the use of research in different documents.
                The intervention did not demonstrate any evidence of effects on the objective behaviour outcomes. We found, however, a statistical significant difference between the two groups for both knowledge scores: Mean difference of 0.4 (95% CI: 0.2-0.6) in the score for knowledge about EBM-resources and mean difference of 0.2 (95% CI: 0.0-0.3) in the score for conceptual knowledge of importance for critical appraisal. There were no statistical significant differences in attitude-, self-efficacy-, decision-to-adopt- or job-satisfaction scales. There were no significant differences in Cochrane library searching after controlling for baseline values and characteristics.
                Though demonstrating effect on knowledge the study failed to provide support for the hypothesis that a theory-based multifaceted intervention targeted at identified barriers will change professional behaviour. Research is needed to validate effective and practical strategies for improving the provision of evidence-based medicine in primary care.
                To determine whether a multimethod quality improvement intervention was more effective than a less intensive intervention for improving adherence to 21 quality indicators for primary and secondary prevention of cardiovascular disease and stroke.
                2-year randomized, controlled clinical trial with the practice as the unit of randomization.
                20 community-based family or general internal medicine practices in 14 states. All used the same electronic medical record.
                44 physicians, 17 midlevel providers, and approximately 200 staff members; data from the electronic medical records of 87,291 patients.
                All practices received copies of practice guidelines and quarterly performance reports. Intervention practices also hosted quarterly site visits to help them adopt quality improvement approaches and participated in 2 network meetings to share "best practice" approaches.
                The percentage of indicators at or above predefined targets and the percentage of patients who had achieved each clinical indicator.
                Intervention practices improved 22.4 percentage points (from 11.3% to 33.7%) in the percentage of indicators at or above the target; control practices improved 16.4 percentage points (from 6.3% to 22.7%). The 6.0-percentage point absolute difference between the intervention and control group was not statistically significant (P > 0.2). Patients in intervention practices had greater improvements than those in control practices for diagnoses of hypertension (improvement difference, 15.7 percentage points [95% CI, 5.2 to 26.3 percentage points]) and blood pressure control in patients with hypertension (improvement difference, 8.0 percentage points [CI, 0.0 to 16.0 percentage points]).
                The study involved a small number of practices and lacked a pure control group.
                Primary care practices that use electronic medical records and receive regular performance reports can improve their adherence to clinical practice guidelines for cardiovascular disease and stroke prevention. To determine if an evidence-based implementation (EBI) could lead to the successful implementation of evidence based care for adult asthma in small rural district hospitals.
                A controlled trial involving eight small rural hospitals (four each in the study and control groups) was conducted. Retrospective pre-intervention audits were conducted at all eight hospitals for 7 months (1 January 2004 to 31 July 2004) and evidence-practice gaps identified. An EBI was then used to implement established guidelines for the management of asthma in the study hospitals. Post-intervention audits were then performed over a period of 7 months (1 October 2004 to 31 April 2005).
                There were 52 presentations of asthma in the study hospitals in the pre-implementation phase and 47 post-implementation. The corresponding numbers for the control hospitals were 46 and 42 respectively. There were no statistically significant differences in the severity between the groups. Following the EBI there were significant improvements at the study hospitals for the documentation of severity (8% to 62%, p <0.001), use of spirometry (12% to 62%, p <0.001) and the use of written short-term asthma plans (9% to 26%, p = 0.05). There was a decrease in use of ipratropium in mild asthma (44% to 30%, p = 0.228), an increase in the use of systemic steroids (61% to 72%, p = 0.255) and no change in prescribing antibiotics for afebrile patients with asthma (21% to 21% p = 0.956). There was no significant change in practice at the control hospitals except for a decrease in the use of systemic steroids (48% to 21%, p = 0.011). For the six clinical indicators aggregate there was a significant increase in compliance with guidelines at the study hospitals (36% to 62%, p < 0.001) but no change at the control hospitals (31% to 31%, p = 0.970).
                The pre-intervention audits demonstrated low levels of compliance with asthma guidelines across six clinical indicators. An EBI significantly improved compliance across these six indicators, and no improvement was noted in the control hospitals. This study demonstrates that an EBI can alter clinical practice in small rural district hospitals. Significant resources and time are invested in the production of research knowledge. The primary objective of this randomized controlled trial was to evaluate the effectiveness of three knowledge translation and exchange strategies in the incorporation of research evidence into public health policies and programs.
                This trial was conducted with a national sample of public health departments in Canada from 2004 to 2006. The three interventions, implemented over one year in 2005, included access to an online registry of research evidence; tailored messaging; and a knowledge broker. The primary outcome assessed the extent to which research evidence was used in a recent program decision, and the secondary outcome measured the change in the sum of evidence-informed healthy body weight promotion policies or programs being delivered at health departments. Mixed-effects models were used to test the hypotheses.
                One hundred and eight of 141 (77%) health departments participated in this study. No significant effect of the intervention was observed for primary outcome (p < 0.45). However, for public health policies and programs (HPPs), a significant effect of the intervention was observed only for tailored, targeted messages (p < 0.01). The treatment effect was moderated by organizational research culture (e.g., value placed on research evidence in decision making).
                The results of this study suggest that under certain conditions tailored, targeted messages are more effective than knowledge brokering and access to an online registry of research evidence. Greater emphasis on the identification of organizational factors is needed in order to implement strategies that best meet the needs of individual organizations.
                The trial registration number and title are as follows: ISRCTN35240937 -- Is a knowledge broker more effective than other strategies in promoting evidence-based physical activity and healthy body weight programming? To assess the efficacy and cost-effectiveness of pelvic floor muscle therapies (PFMT) in women aged > or = 40 years with urodynamic stress incontinence (USI) and mixed UI.
                In a three-arm randomized controlled trial in Leicestershire and Rutland UK, 238 community-dwelling women aged > or = 40 years with USI in whom previous primary behavioural intervention had failed were randomized to receive either intensive PFMT (79), vaginal cone therapy (80) or to continue with primary behavioural intervention (79) for 3 months. The main outcome measure was the frequency of primary UI episodes, and secondary measures were pad-test urine loss, patient perception of problem, assessment of PF function, voiding frequency, and pad usage. Validated scales for urinary dysfunction, and impact on quality of life and satisfaction were collected at an independent interview.
                All three groups had a moderate reduction in UI episodes after intervention but there was no statistically significant difference among the groups. There were marginal improvements in voiding frequency for all groups, with no statistically significant difference among them.
                In women who have already had simple behavioural therapies (including advice on PFM exercises) for urinary dysfunction, the continuation of these behavioural therapies can lead to further improvement. The addition of vaginal cone therapy or intensive PFMT does not seem to contribute to further improvement. The improvement in pelvic floor function was significantly greater in the PFMT arm than in the control arm although this did not translate into changes in urinary symptoms. Quality improvement initiatives in health services rely upon the effective introduction of clinical practice guidelines. However, even well constructed guidelines have little effect unless supported by dissemination and implementation strategies.
                To test the effectiveness of 'educational outreach' as a strategy for facilitating the uptake of dyspepsia management guidelines in primary care.
                A pragmatic, cluster-randomised controlled trial of guideline introduction, comparing educational outreach with postal guideline dissemination alone.
                One-hundred and fourteen general practices (233 general practitioners) in the Salford and Trafford Health authority catchment area in the northwest of England.
                All practices received guidelines by post in July 1997. The intervention group practices began to receive educational outreach three months later. This consisted of practice-based seminars with hospital specialists at which guideline recommendations were appraised, and implementation plans formulated. Seminars were followed up with 'reinforcement' visits after a further 12 weeks. Outcome measures were: (a) the appropriateness of referral for; and (b) findings at, open access upper gastrointestinal endoscopy; (c) costs of GP prescriptions for acid-suppressing drugs, and (d) the use of laboratory-based serological tests for Helicobacter pylori. Data were collected for seven months before and/or after the intervention and analysed by intention-to-treat.
                (a) The proportion of appropriate referrals was higher in the intervention group in the six-month post-intervention period (practice medians: control = 50.0%, intervention = 63.9%, P < 0.05); (b) the proportion of major findings at endoscopy did not alter significantly; (c) there was a greater rise in overall expenditure on acid-suppressing drugs in the intervention as compared with the control group (+8% versus +2%, P = 0.005); and (d) the median testing rate per practice for H pylori in the post-intervention period was significantly greater in the intervention group (four versus O, P < 0.001).
                This study suggests that educational outreach may be more effective than passive guideline dissemination in changing clinical behaviour. It also demonstrates that unpredictable and unanticipated outcomes may emerge. We conducted a trial to evaluate the effect of an active, multifaceted educational strategy to promote the use of the WHO Reproductive Health Library (RHL) on obstetric practices.
                Cluster randomised trial. The trial was assigned the International Standardised Randomised Controlled Trial Number ISRCTN14055385.
                Twenty-two hospitals in Mexico City and 18 in the Northeast region of Thailand.
                The intervention consisted primarily of three interactive workshops using RHL over a period of 6 months. The focus of the workshops was to provide access to knowledge and enable its use. A computer and support for using both the computer and RHL were provided at each hospital. The control hospitals did not receive any intervention.
                The main outcome measures were changes in ten selected clinical practices as recommended in RHL starting approximately four to six months after the third workshop. Clinical practice data were collected at each hospital from 1000 consecutively delivered women or for a 6-month period whichever was reached sooner.
                The active, multifaceted educational intervention we employed did not affect the ten targeted practices in a consistent and substantive way. Iron/folate supplementation, uterotonic use after birth and breastfeeding on demand were already frequently practiced, and we were unable to measure external cephalic version. Of the remaining six practices, selective, as opposed to routine episiotomy policy increased in the intervention group (difference in adjusted mean rate = 5.3%; 95% CI -0.1 to 10.7%) in Thailand, and there was a trend towards an increased use of antibiotics at caesarean section in Mexico (difference in adjusted mean rate = 19.0%; 95% CI: -8.0 to 46.0%). There were no differences in the use of labour companionship, magnesium sulphate use for eclampsia, corticosteroids for women delivering before 34 weeks and vacuum extraction. RHL awareness (24.8-65.5% in Mexico and 33.9-83.3% in Thailand) and use (4.8-34.9% in Mexico and 15.5-76.4% in Thailand) increased substantially after the intervention in both countries.
                The multifaceted, active strategy to provide health workers with the knowledge and skills to use RHL to improve their practice led to increased access to and use of RHL, however, no consistent or substantive changes in clinical practices were detected within 4-6 months after the third workshop. To evaluate the effectiveness of a multifaceted intervention to improve the clinical decision making of general practitioners (GPs) for patients with diabetes. To identify practice characteristics which predict success.
                Cluster randomized controlled trial with 124 practices and 185 GPs in The Netherlands. The intervention group received feedback reports and support from a facilitator; the control group received no special attention. Outcome measures were the compliance rates with evidence-based recommendations pertaining to discussion of body weight control, discussion of problems with medication, blood pressure measurement, foot examination, eye examination, initiating anti-diabetic medication or increasing the dosage in cases of uncontrolled blood glucose, and scheduling a follow-up appointment.
                The GPs reported on their clinical decision making in 1410 consultations with Type 2 diabetic patients at baseline and 1449 consultations after the intervention period. The intervention resulted in statistically significant improvement for two of the seven outcome measures: foot examination (odds ratio 1.68; 95% confidence interval 1.19-2.39) and eye examination (1.52; 1.07-2.16). Discussion of problems with medication showed a near significant trend towards increased benefit for the intervention group (1.52; 0.99-2.32). Practice characteristics were not found to be related to the success of the intervention.
                Feedback reports with support from facilitators appear to increase rates of foot examination and eye examination in general practice. Alternative interventions should be explored to improve the pursuit of metabolic control by GPs.
The results of this review suggest that when used alone and compared to no intervention, PEMs may have a small beneficial effect on professional practice outcomes. There is insufficient information to reliably estimate the effect of PEMs on patient outcomes, and clinical significance of the observed effect sizes is not known. The effectiveness of PEMs compared to other interventions, or of PEMs as part of a multifaceted intervention, is uncertain.
