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

Community implementation of a brief parent mediated intervention for toddlers with probable or confirmed autism spectrum disorder: feasibility, acceptability, and drivers of success (IE Drmic et al.)

Background

Social ABCs is a caregiver-mediated Naturalistic Developmental Behavioral Intervention for toddlers with confirmed/suspected Autism Spectrum Disorder (ASD), with evidence in controlled research settings. Information is lacking on implementation in community settings. We reported on the treatment effectiveness of this program within a community setting, and the current paper describes the implementation phase of this work. Distinguishing between treatment and implementation effectiveness is critical for transporting interventions from laboratory to community.

Objectives

Describe the implementation of Social ABCs through a large public autism service, supported by a research-community partnership.

Methods

We describe this project through the Exploration, Preparation, Implementation, Sustainment (EPIS) framework as it focuses on implementation of evidence-based practices in publicly funded services. We apply this framework to the reporting stage. This project took place in the context of a 3-year government-funded pilot at a hospital-based publicly funded autism service. Participants: Program developers; Autism Service team; toddlers with suspected/confirmed ASD aged 14-34 months (M = 25.18 months) and their caregivers. Training/supervision: Provided by program developers at tapering intensity. Evaluation: Caregivers completed the Caregiver Diary and satisfaction surveys. We explored training processes, intervention uptake, acceptability, adaptations to fit community context, appropriateness, perceived impact, and facilitators/barriers.

Results

Six coaches were trained to fidelity, and three of these were further trained as Site Trainers. 183 clinically referred families enrolled and 89.4% completed the 12-week program. Caregivers reported increases in adherence and competence, high satisfaction and perceived benefits for their children. Coaches reported high satisfaction. Toddlers were appropriately identified to receive the intervention. Referral processes improved, including decreased referral age, and increased family readiness for diagnostic assessment and subsequent services.

Conclusions

Social ABCs was successfully implemented in a community service through a research-community partnership. The program was feasible, acceptable, and appropriate within a community context. Drivers of success included funding, institutional support, shared decision-making, adaptations to fit context, leadership support, perceived positive impact, and commitment to evaluation.

Knowledge translation strategies to support the sustainability of evidence-based interventions in healthcare: a scoping review

BACKGROUND

Knowledge translation (KT) strategies are widely used to facilitate the implementation of EBIs into healthcare practices. However, it is unknown what and how KT strategies are used to facilitate the sustainability of EBIs in institutional healthcare settings.

OBJECTIVES

This scoping review aimed to consolidate the current evidence on (i) what and how KT strategies are being used for the sustainability of EBIs in institutional healthcare settings; (ii) the reported KT strategy outcomes (e.g., acceptability) for EBI sustainability, and (iii) the reported EBI sustainability outcomes (e.g., EBI activities or component of the intervention continue).

METHODS

We conducted a scoping review of five electronic databases. We included studies describing the use of specific KT strategies to facilitate the sustainability of EBIs (more than 1-year post-implementation). We coded KT strategies using the clustered ERIC taxonomy and AIMD framework, we coded KT strategy outcomes using Tierney et al.'s measures, and EBI sustainability outcomes using Scheirer and Dearing's and Lennox's taxonomy. We conducted descriptive numerical summaries and a narrative synthesis to analyze the results.

RESULTS

The search identified 3776 studies for review. Following the screening, 25 studies (reported in 27 papers due to two companion reports) met the final inclusion criteria. Most studies used multi-component KT strategies for EBI sustainability (n = 24). The most common ERIC KT strategy clusters were to train and educate stakeholders (n = 38) and develop stakeholder interrelationships (n = 34). Education was the most widely used KT strategy (n = 17). Many studies (n = 11) did not clearly report whether they used different or the same KT strategies between EBI implementation and sustainability. Seven studies adapted KT strategies from implementation to sustainability efforts. Only two studies reported using a new KT strategy for EBI sustainability. The most reported KT strategy outcomes were acceptability (n = 10), sustainability (n = 5); and adoption (n = 4). The most commonly measured EBI sustainability outcome was the continuation of EBI activities or components (n = 23), followed by continued benefits for patients, staff, and stakeholders (n = 22).

CONCLUSIONS

Our review provides insight into a conceptual problem where initial EBI implementation and sustainability are considered as two discrete time periods. Our findings show we need to consider EBI implementation and sustainability as a continuum and design and select KT strategies with this in mind. Our review has emphasized areas that require further research (e.g., KT strategy adaptation for EBI sustainability). To advance understanding of how to employ KT strategies for EBI sustainability, we recommend clearly reporting the dose, frequency, adaptations, fidelity, and cost of KT strategies. Advancing our understanding in this area would facilitate better design, selection, tailored, and adapted use of KT strategies for EBI sustainability, thereby contributing to improved patient, provider, and health system outcomes.

Internet-based interventions for perinatal depression and anxiety symptoms: an ethnographic qualitative study exploring the views and opinions of midwives in Switzerland

Background

Mental disorders such as depression and anxiety are common during pregnancy and postpartum, but are frequently underdiagnosed and untreated. In the last decades, internet-based interventions have emerged as a treatment alternative showing similar effectiveness to face-to-face psychotherapy. We aimed to explore midwives’ perceptions of the acceptability of internet-based interventions for the treatment of perinatal depression and anxiety symptoms.

Methods

In this ethnographic qualitative study, semi-structured interviews were conducted with 30 midwives. We followed the Consolidated Criteria for Reporting Qualitative Research Checklist (COREQ). Audio-recorded interviews were transcribed verbatim and analysed using framework analysis. The identified framework categories were rated individually by two independent raters. Krippendorff’s alpha coefficient was used to ensure the reliability of the rating.

Results

Four main themes emerged: midwives’ experience with patients’ mental health issues; the role of healthcare workers in women’s utilisation of internet-based interventions in the perinatal period; the overall perception of internet-based interventions; and recommendation of internet-based interventions to perinatal women. Twenty-five of the 30 participants viewed internet-based interventions as an acceptable type of intervention, which they would recommend to a subgroup of patients (e.g. women who are well-educated or younger). All except for two midwives identified themselves and medical doctors as key figures regarding patients’ utilisation of internet-based interventions, although a third of the interviewees highlighted that they needed sufficient information about such interventions. Finally, several participants suggested features which could be relevant to develop more acceptable and feasible internet-based interventions in the future.

Discussion

Participants’ overall perception of internet-based interventions for perinatal depression and anxiety symptoms was positive. This study underlines the importance of considering midwives’ views about internet-based interventions for perinatal mental health care. Our findings have implications for the practice not only of midwives but also of other maternity care professionals. Future studies examining the views of other health professionals are warranted.

• There is a lack of studies on health professionals’ views about women’s utilisation of internet-based interventions in the perinatal period.

• Our findings suggest that midwives have a positive perception of internet-based interventions, despite identifying disadvantages and having concerns about their use.

• These findings are encouraging and contribute to the continued efforts to develop internet-based mental health interventions as a way to support perinatal women screened or diagnosed with anxiety and/or depressive symptoms.

Personalized symptom management: a quality improvement collaborative for implementation of patient reported outcomes (PROs) in 'real-world' oncology multisite practices

Background

Little research has focused on implementation of electronic Patient Reported Outcomes (e-PROs) for meaningful use in patient management in ‘real-world’ oncology practices. Our quality improvement collaborative used multi-faceted implementation strategies including audit and feedback, disease-site champions and practice coaching, core training of clinicians in a person-centered clinical method for use of e-PROs in shared treatment planning and patient activation, ongoing educational outreach and shared collaborative learnings to facilitate integration of e-PROs data in multi-sites in Ontario and Quebec, Canada for personalized management of generic and targeted symptoms of pain, fatigue, and emotional distress (depression, anxiety).

Patients and methods

We used a mixed-methods (qualitative and quantitative data) program evaluation design to assess process/implementation outcomes including e-PROs completion rates, acceptability/use from the perspective of patients/clinicians, and patient experience (surveys, qualitative focus groups). We secondarily explored impact on symptom severity, patient activation and healthcare utilization (Ontario sites only) comparing a pre/post population cohort not exposed/exposed to our implementation intervention using Mann Whitney U tests. We hypothesized that the iPEHOC intervention would result in a reduction in symptom severity, healthcare utilization, and higher patient activation. We also identified key implementation strategies that sites perceived as most valuable to uptake and any barriers.

Results

Over 6000 patients completed e-PROs, with sites reaching 51%–95% population completion rates depending on initial readiness. e-PROs were acceptable to patients for communicating symptoms (76%) and by clinicians for treatment planning (80%). Patient experience was better than the provincial average. Compared to the pre-population, we observed a significant reduction in levels of anxiety (p = 0.008), higher levels of patient activation (p = 0.045), and reduced hospitalization rates (12.3% not exposed vs 10.1% exposed, p = 0.034). A pre/post population trend towards significance for reduced emergency department visit rates (14.8% not exposed vs 12.8% exposed, p = 0.081) was also noted.

Conclusion

This large-scale pragmatic quality improvement project demonstrates the impact of implementation strategies and a collaborative improvement approach on acceptability of using PROs in clinical practice and their potential for reducing anxiety and healthcare utilization; and improving patient experience and patient activation when implemented in ‘real-world’ multi-site oncology practices.

Initiation is recognized as a fundamental early phase of integrated knowledge translation (IKT): qualitative interviews with researchers and research users in IKT partnerships

Background

Health care researcher-research user partnerships, referred to as integrated knowledge translation (IKT), have been adopted on an international basis, and are an effective means of co-generating and implementing evidence into policy and practice. Prior research suggests that an initiation period is essential for establishing functional partnerships. To characterize IKT initiation and describe determinants of IKT initiation success, this study explored IKT initiation processes, enablers, and barriers among researchers and research users involved in IKT partnerships.

Methods

A descriptive qualitative approach was used compliant with COREQ standards. Canadian researchers and research users in research collaborations were identified on publicly-available directories and web sites, and referred by those interviewed. They were asked to describe how partnerships were initiated, influencing factors, the length of initiation, and interventions needed to support initiation. Sampling was concurrent with data collection and analysis to achieve thematic saturation. Data were analyzed using constant comparative technique by all members of the research team.

Results

In total, 22 individuals from 6 provinces were interviewed (9 researchers, 11 research users, 2 connectors). They confirmed that IKT initiation is a distinct early phase of partnerships. The period ranged from 6 months to 2 years for 75.0% of participants in pre-existing partnerships, to 6 years for newly-formed partnerships. High-level themes were: Newly identifying and securing partners is an intensive process; Processes and activities take place over a protracted period through multiple interactions; Identifying and engaging committed partners is reliant on funding; and Partnership building is challenged by maintaining continuity and enthusiasm. Participants underscored the need for an IKT partner matching forum, IKT initiation toolkit, and funding for non-research activities required during IKT initiation to establish functional researcher-research user partnerships. Themes were largely similar regardless of participant years of experience with IKT or being involved in a new versus pre-existing partnership.

Conclusions

IKT initiation is a recognized and important early phase of IKT that establishes functional partnerships, and once established, ongoing partnership for subsequent projects is likely. Further research is needed to develop and evaluate approaches recommended by participants for stimulating IKT initiation.

Exploring pathways to mental healthcare for urban Aboriginal young people: a qualitative interview study

OBJECTIVES

To explore the perceptions of Aboriginal Community Controlled Health Service (ACCHS) staff involved in providing mental healthcare to Aboriginal young people of the current and ideal pathways to mental healthcare for urban Aboriginal young people attending ACCHSs, and to identify what additional supports staff may need to provide optimal mental healthcare to Aboriginal young people.

DESIGN

Qualitative interview study conducted during May 2016-2017.

SETTING

Primary care, at two ACCHSs participating in the Study of Environment on Aboriginal Resilience and Child Health in New South Wales.

PARTICIPANTS

Purposive sampling of staff involved in mental healthcare pathways of Aboriginal young people, including general practitioners (GPs), nurses and Aboriginal Health Workers (AHWs).

RESULTS

All individuals approached for interview (n=21) participated in the study. Four overarching themes and seven sub-themes were identified: availability and use of tools in practice (valuing training and desire for tools and established pathways), targeting the ideal care pathway (initiating care and guiding young people through care), influencing the care pathway (adversities affecting access to care and adapting the care pathway) and assessing future need (appraising service availability).

CONCLUSIONS

Participants desired screening tools, flexible guidelines and training for healthcare providers to support pathways to mental healthcare for Aboriginal young people. Both GPs and AHWs were considered key in identifying children at risk and putting young people onto a pathway to receive appropriate mental healthcare. AHWs were deemed important in keeping young people on the care pathway, and participants felt care pathways could be improved with the addition of dedicated child and adolescent AHWs. The ACCHSs were highlighted as essential to providing culturally appropriate care for Aboriginal young people experiencing mental health problems, and funding for mental health specialists to be based at the ACCHSs was considered a priority.

Local opinion leaders: effects on professional practice and healthcare outcomes

BACKGROUND

Clinical practice is not always evidence-based and, therefore, may not optimise patient outcomes. Local opinion leaders (OLs) are individuals perceived as credible and trustworthy, who disseminate and implement best evidence, for instance through informal one-to-one teaching or community outreach education visits. The use of OLs is a promising strategy to bridge evidence-practice gaps. This is an update of a Cochrane review published in 2011.

OBJECTIVES

To assess the effectiveness of local opinion leaders to improve healthcare professionals' compliance with evidence-based practice and patient outcomes.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, three other databases and two trials registers on 3 July 2018, together with searching reference lists of included studies and contacting experts in the field.

SELECTION CRITERIA

We considered randomised studies comparing the effects of local opinion leaders, either alone or with a single or more intervention(s) to disseminate evidence-based practice, with no intervention, a single intervention, or the same single or more intervention(s). Eligible studies were those reporting objective measures of professional performance, for example, the percentage of patients being prescribed a specific drug or health outcomes, or both. We included all studies independently of the method used to identify OLs.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane procedures in this review. The main comparison was (i) between any intervention involving OLs (OLs alone, OLs with a single or more intervention(s)) versus any comparison intervention (no intervention, a single intervention, or the same single or more intervention(s)). We also made four secondary comparisons: ii) OLs alone versus no intervention, iii) OLs alone versus a single intervention, iv) OLs, with a single or more intervention(s) versus the same single or more intervention(s), and v) OLs with a single or more intervention(s) versus no intervention.

MAIN RESULTS

We included 24 studies, involving more than 337 hospitals, 350 primary care practices, 3005 healthcare professionals, and 29,167 patients (not all studies reported this information). A majority of studies were from North America, and all were conducted in high-income countries. Eighteen of these studies (21 comparisons, 71 compliance outcomes) contributed to the median adjusted risk difference (RD) for the main comparison. The median duration of follow-up was 12 months (range 2 to 30 months). The results suggested that the OL interventions probably improve healthcare professionals' compliance with evidence-based practice (10.8% absolute improvement in compliance, interquartile range (IQR): 3.5% to 14.6%; moderate-certainty evidence).Results for the secondary comparisons also suggested that OLs probably improve compliance with evidence-based practice (moderate-certainty evidence): i) OLs alone versus no intervention: RD (IQR): 9.15% (-0.3% to 15%); ii) OLs alone versus a single intervention: RD (range): 13.8% (12% to 15.5%); iii) OLs, with a single or more intervention(s) versus the same single or more intervention(s): RD (IQR): 7.1% (-1.4% to 19%); iv) OLs with a single or more intervention(s) versus no intervention: RD (IQR):10.25% (0.6% to 15.75%).It is uncertain if OLs alone, or in combination with other intervention(s), may lead to improved patient outcomes (3 studies; 5 dichotomous outcomes) since the certainty of evidence was very low. For two of the secondary comparisons, the IQR included the possibility of a small negative effect of the OL intervention. Possible explanations for the occasional negative effects are, for example, the possibility that the OLs may have prioritised some outcomes, at the expense of others, or that an unaccounted outcome difference at baseline, may have given a faulty impression of a negative effect of the intervention at follow-up. No study reported on costs or cost-effectiveness.We were unable to determine the comparative effectiveness of different approaches to identifying OLs, as most studies used the sociometric method. Nor could we determine which methods used by OLs to educate their peers were most effective, as the methods were poorly described in most studies. In addition, we could not determine whether OL teams were more effective than single OLs.

AUTHORS' CONCLUSIONS

Local opinion leaders alone, or in combination with other interventions, can be effective in promoting evidence-based practice, but the effectiveness varies both within and between studies.The effect on patient outcomes is uncertain. The costs and the cost-effectiveness of the intervention(s) is unknown. These results are based on heterogeneous studies differing in types of intervention, setting, and outcomes. In most studies, the role and actions of the OL were not clearly described, and we cannot, therefore, comment on strategies to enhance their effectiveness. It is also not clear whether the methods used to identify OLs are important for their effectiveness, or whether the effect differs if education is delivered by single OLs or by multidisciplinary OL teams. Further research may help us to understand how these factors affect the effectiveness of OLs.

Diffusing innovative road safety practice: A social network approach to identifying opinion leading U.S. cities

OBJECTIVE

This study sought to identify opinion-leading U.S. cities in the realm of safe transportation systems by surveying road safety professionals and asking them to identify places that served as models for road safety.

METHODS

Using a purposive sampling methodology, we surveyed professionals employed in road safety-related professions (e.g., transportation engineering, planning, public health, law enforcement, and emergency response). Using 183 professionals' complete responses, we carried out social network analysis to both describe the structure of intermunicipal advice-seeking patterns among road safety professionals and identify those municipalities with relatively high degrees of influence.

RESULTS

We discovered a large intermunicipal monitoring network related to improving road user safety. Half of the network ties (50.4%) crossed regional U.S. census boundaries. Social network statistics informed the identification of 7 opinion-leader and 4 boundary-spanning municipalities.

CONCLUSIONS

This study indicated a large intermunicipal monitoring network, half of which crossed regional boundaries. Road safety professionals have formed a country-spanning example-following network on the topic of improving road user safety in the United States. Researchers and intervention teams can tap into this network to accelerate the uptake and spread of evidence-based road safety practices.

Why (we think) facilitation works: insights from organizational learning theory

Background

Facilitation is a guided interactional process that has been popularized in health care. Its popularity arises from its potential to support uptake and application of scientific knowledge that stands to improve clinical and managerial decision-making, practice, and ultimately patient outcomes and organizational performance. While this popular concept has garnered attention in health services research, we know that both the content of facilitation and its impact on knowledge implementation vary. The basis of this variation is poorly understood, and understanding is hampered by a lack of conceptual clarity.

Discussion

In this paper, we argue that our understanding of facilitation and its effects is limited in part by a lack of clear theoretical grounding. We propose a theoretical home for facilitation in organizational learning theory. Referring to extant literature on facilitation and drawing on theoretical literature, we discuss the features of facilitation that suggest its role in contributing to learning capacity. We describe how facilitation may contribute to generating knowledge about the application of new scientific knowledge in health-care organizations.

Summary

Facilitation’s promise, we suggest, lies in its potential to stimulate higher-order learning in organizations through experimenting with, generating learning about, and sustaining small-scale adaptations to organizational processes and work routines. The varied effectiveness of facilitation observed in the literature is associated with the presence or absence of factors known to influence organizational learning, since facilitation itself appears to act as a learning mechanism. We offer propositions regarding the relationships between facilitation processes and key organizational learning concepts that have the potential to guide future work to further our understanding of the role that facilitation plays in learning and knowledge generation.

Exploring the influence of context in a community-based facilitation intervention focusing on neonatal health and survival in Vietnam: a qualitative study

BACKGROUND

In the Neonatal health - Knowledge into Practice (NeoKIP) trial in Vietnam, local stakeholder groups, supported by trained laywomen acting as facilitators, promoted knowledge translation (KT) resulting in decreased neonatal mortality. In general, as well as in the community-based NeoKIP trial, there is a need to further understand how context influences KT interventions in low- and middle-income countries (LMICs). Thus, the objective of this study was to explore the influence of context on the facilitation process in the NeoKIP intervention.

METHODS

A secondary content analysis was performed on 16 Focus Group Discussions with facilitators and participants of the stakeholder groups, applying an inductive approach to the content on context through naïve understanding and structured analysis.

RESULTS

The three main-categories of context found to influence the facilitation process in the NeoKIP intervention were: (1) Support and collaboration of local authorities and other communal stakeholders; (2) Incentives to, and motivation of, participants; and (3) Low health care coverage and utilization. In particular, the role of local authorities in a KT intervention was recognized as important. Also, while project participants expected financial incentives, non-financial benefits such as individual learning were considered to balance the lack of reimbursement in the NeoKIP intervention. Further, project participants recognized the need to acknowledge the needs of disadvantaged groups.

CONCLUSIONS

This study provides insight for further understanding of the influence of contextual aspects to improve effects of a KT intervention in Vietnam. We suggest that future KT interventions should apply strategies to improve local authorities' engagement, to identify and communicate non-financial incentives, and to make disadvantaged groups a priority. Further studies to evaluate the contextual aspects in KT interventions in LMICs are also needed.

Increases in Network Ties Are Associated With Increased Cohesion Among Intervention Participants

OBJECTIVE

Many behavior change programs are delivered in group settings to manage implementation costs and to foster support and interactions among group members in order to facilitate behavior change. Understanding the group dynamics that evolve in group settings (e.g., weight management, Alcoholics Anonymous) is important, yet rarely measured. This article examined the relationship between social network ties and group cohesion in a group-based intervention to prevent obesity in children.

METHOD

The data reported are process measures from an ongoing community-based randomized controlled trial. A total of 305 parents with a child (3-6 years) at risk of developing obesity were assigned to an intervention that taught parents healthy lifestyles. Parents met weekly for 12 weeks in small consistent groups. Two measures were collected at Weeks 3 and 6: a social network survey (people in the group with whom one discusses healthy lifestyles) and the validated Perceived Cohesion Scale. We used lagged random and fixed effects regression models to analyze the data.

RESULTS

Cohesion increased from 6.51 to 6.71 (t= 4.4,p< .01). Network nominations tended to increase over the 3-week period in each network. In the combined discussion and advice network, the number of nominations increased from 1.76 to 1.95 (z= 2.59,p< .01). Cohesion at Week 3 was the strongest predictor of cohesion at Week 6 (b= 0.55,p< .01). Number of new network nominations at Week 6 was positively related to cohesion at Week 6 (b= 0.06,p< .01). In sum, being able to name new network contacts was associated with feelings of cohesion.

CONCLUSION

This is the first study to demonstrate how network changes affect perceived group cohesion within a behavioral intervention. Given that many behavioral interventions occur in group settings, intentionally building new social networks could be promising to augment desired outcomes.

The influence of context on the effectiveness of hospital quality improvement strategies: a review of systematic reviews

Background

It is now widely accepted that the mixed effect and success rates of strategies to improve quality and safety in health care are in part due to the different contexts in which the interventions are planned and implemented. The objectives of this study were to (i) describe the reporting of contextual factors in the literature on the effectiveness of quality improvement strategies, (ii) assess the relationship between effectiveness and contextual factors, and (iii) analyse the importance of contextual factors.

Methods

We conducted an umbrella review of systematic reviews searching the following databases: PubMed, Cochrane Database of Systematic Reviews, Embase and CINAHL. The search focused on quality improvement strategies included in the Cochrane Effective Practice and Organisation of Care Group taxonomy. We extracted data on quality improvement effectiveness and context factors. The latter were categorized according to the Model for Understanding Success in Quality tool.

Results

We included 56 systematic reviews in this study of which only 35 described contextual factors related with the effectiveness of quality improvement interventions. The most frequently reported contextual factors were: quality improvement team (n = 12), quality improvement support and capacity (n = 11), organization (n = 9), micro-system (n = 8), and external environment (n = 4). Overall, context factors were poorly reported. Where they were reported, they seem to explain differences in quality improvement effectiveness; however, publication bias may contribute to the observed differences.

Conclusions

Contextual factors may influence the effectiveness of quality improvement interventions, in particular at the level of the clinical micro-system. Future research on the implementation and effectiveness of quality improvement interventions should emphasize formative evaluation to elicit information on context factors and report on them in a more systematic way in order to better appreciate their relative importance.

The role of evidence and context for implementing a multimodal intervention to increase HIV testing

Background

Increasing the use of routine preventive care such as HIV testing is important, yet implementation of such evidence-based clinical care is complex. The Promoting Action on Research Implementation in Health Services (PARiHS) model for implementation posits that implementation will be most successful when the evidence, context, and facilitation strategies are strong for the clinical practice. We evaluated the relative importance of perceived evidence, context, and facilitation of HIV testing during the implementation of a multimodal intervention in US Department of Veterans Affairs primary care clinics.

Methods

A multimodal intervention including clinical reminders (CRs), academic detailing—providing education sessions for providers—and social marketing to improve HIV testing was implemented in 15 VA primary care clinics in three regions. We conducted qualitative formative and process evaluations using semi-structured interviews with HIV lead clinicians, primary care lead clinicians, nurse managers, and social workers. Interviews were analyzed thematically to identify barriers and facilitators to implementation of HIV testing and how these were addressed by the intervention. Sites were then rated high, medium, or low on the dimensions of perceived evidence and the context for testing. We then assessed the relationship of these ratings to improvements in HIV testing rates found in earlier quantitative analyses.

Results

Sites that showed greatest improvements in HIV testing rates also rated high on evidence and context. Conversely, sites that demonstrated the poorest improvements in testing rates rated low on both dimensions. Perceptions of evidence and several contextual aspects resulted in both barriers and facilitators to implementing testing. Evidence barriers included provider perceptions of evidence for routine testing as irrelevant to their population. Contextual barriers included clinical reminder overload, insufficient resources, onerous consent processes, stigma, provider discomfort, and concerns about linking individuals who test positive to HIV treatment. While most barriers were ameliorated by the intervention, HIV stigma in particular regions and concerns about linkage to care persisted.

Conclusions

Interventions to implement evidence-based practices such as HIV testing can be successful when utilizing proven quality improvement techniques. However, it is critical to address providers’ perceptions of evidence and consider aspects of the local context in order to fully implement new routine clinical practices such as HIV testing.

A cluster randomised controlled trial of a pharmacist-led collaborative intervention to improve statin prescribing and attainment of cholesterol targets in primary care

Background

Small trials with short term follow up suggest pharmacists’ interventions targeted at healthcare professionals can improve prescribing. In comparison with clinical guidance, contemporary statin prescribing is sub-optimal and achievement of cholesterol targets falls short of accepted standards, for patients with atherosclerotic vascular disease who are at highest absolute risk and who stand to obtain greatest benefit. We hypothesised that a pharmacist-led complex intervention delivered to doctors and nurses in primary care, would improve statin prescribing and achievement of cholesterol targets for incident and prevalent patients with vascular disease, beyond one year.

Methods

We allocated general practices to a 12-month Statin Outreach Support (SOS) intervention or usual care. SOS was delivered by one of 11 pharmacists who had received additional training. SOS comprised academic detailing and practical support to identify patients with vascular disease who were not prescribed a statin at optimal dose or did not have cholesterol at target, followed by individualised recommendations for changes to management. The primary outcome was the proportion of patients achieving cholesterol targets. Secondary outcomes were: the proportion of patients prescribed simvastatin 40 mg with target cholesterol achieved; cholesterol levels; prescribing of simvastatin 40 mg; prescribing of any statin and the proportion of patients with cholesterol tested. Outcomes were assessed after an average of 1.7 years (range 1.4–2.2 years), and practice level simvastatin 40 mg prescribing was assessed after 10 years.

Findings

We randomised 31 practices (72 General Practitioners (GPs), 40 nurses). Prior to randomisation a subset of eligible patients were identified to characterise practices; 40% had cholesterol levels below the target threshold. Improvements in data collection procedures allowed identification of all eligible patients (n = 7586) at follow up. Patients in practices allocated to SOS were significantly more likely to have cholesterol at target (69.5% vs 63.5%; OR 1.11, CI 1.00–1.23; p = 0.043) as a result of improved simvastatin prescribing. Subgroup analysis showed the primary outcome was achieved by prevalent but not incident patients. Statistically significant improvements occurred in all secondary outcomes for prevalent patients and all but one secondary outcome (the proportion of patients with cholesterol tested) for incident patients. SOS practices prescribed more simvastatin 40 mg than usual care practices, up to 10 years later.

Interpretation

Through a combination of educational and organisational support, a general practice based pharmacist led collaborative intervention can improve statin prescribing and achievement of cholesterol targets in a high-risk primary care based population.

A narrative review of recent developments in knowledge translation and implications for mental health care providers

OBJECTIVE

Attention to knowledge translation (KT) has increased in the health care field in an effort to improve uptake and implementation of potentially beneficial knowledge. We provide an overview of the current state of KT literature and discuss the relevance of KT for health care professionals working in mental health.

METHOD

A systematic search was conducted using MEDLINE, PsycINFO, and CINAHL databases to identify review articles published in journals from 2007 to 2012. We selected articles on the basis of eligibility criteria and then added further articles deemed pertinent to the focus of ourpaper.

RESULTS

After removing duplicates, we scanned 214 review articles for relevance and, subsequently, we added 46 articles identified through hand searches of reference lists or from other sources. A total of 61 papers were retained for full review. Qualitative synthesis identified 5 main themes: defining KT and development of KT science; effective KT strategies; factors influencing the effectiveness of KT; KT frameworks and guides; and relevance of KT to health care providers.

CONCLUSIONS

Despite limitations in existing evidence, the concept and practice of KT holds potential value for mental health care providers. Understanding of, and familiarity with, effective approaches to KT holds the potential to enhance providers' treatment approaches and to promote the use of new knowledge in practice to enhance outcomes.

Central implementation strategies outperform local ones in improving HIV testing in Veterans Healthcare Administration facilities

BACKGROUND

Pilot data suggest that a multifaceted approach may increase HIV testing rates, but the scalability of this approach and the level of support needed for successful implementation remain unknown.

OBJECTIVE

To evaluate the effectiveness of a scaled-up multi-component intervention in increasing the rate of risk-based and routine HIV diagnostic testing in primary care clinics and the impact of differing levels of program support.

DESIGN

Three arm, quasi-experimental implementation research study.

SETTING

Veterans Health Administration (VHA) facilities.

PATIENTS

Persons receiving primary care between June 2009 and September 2011 INTERVENTION: A multimodal program, including a real-time electronic clinical reminder to facilitate HIV testing, provider feedback reports and provider education, was implemented in Central and Local Arm Sites; sites in the Central Arm also received ongoing programmatic support. Control Arm sites had no intervention

MAIN MEASURES

Frequency of performing HIV testing during the 6 months before and after implementation of a risk-based clinical reminder (phase I) or routine clinical reminder (phase II).

KEY RESULTS

The adjusted rate of risk-based testing increased by 0.4 %, 5.6 % and 10.1 % in the Control, Local and Central Arms, respectively (all comparisons, p < 0.01). During phase II, the adjusted rate of routine testing increased by 1.1 %, 6.3 % and 9.2 % in the Control, Local and Central Arms, respectively (all comparisons, p < 0.01). At study end, 70-80 % of patients had been offered an HIV test.

CONCLUSIONS

Use of clinical reminders, provider feedback, education and social marketing significantly increased the frequency at which HIV testing is offered and performed in VHA facilities. These findings support a multimodal approach toward achieving the goal of having every American know their HIV status as a matter of routine clinical practice.

Discovering opinion leaders for medical topics using news articles

Background

Rapid identification of subject experts for medical topics helps in improving the implementation of discoveries by speeding the time to market drugs and aiding in clinical trial recruitment, etc. Identifying such people who influence opinion through social network analysis is gaining prominence. In this work, we explore how to combine named entity recognition from unstructured news articles with social network analysis to discover opinion leaders for a given medical topic.

Methods

We employed a Conditional Random Field algorithm to extract three categories of entities from health-related new articles: Person, Organization and Location. We used the latter two to disambiguate polysemy and synonymy for the person names, used simple rules to identify the subject experts, and then applied social network analysis techniques to discover the opinion leaders among them based on their media presence. A network was created by linking each pair of subject experts who are mentioned together in an article. The social network analysis metrics (including centrality metrics such as Betweenness, Closeness, Degree and Eigenvector) are used for ranking the subject experts based on their power in information flow.

Results

We extracted 734,204 person mentions from 147,528 news articles related to obesity from January 1, 2007 through July 22, 2010. Of these, 147,879 mentions have been marked as subject experts. The F-score of extracting person names is 88.5%. More than 80% of the subject experts who rank among top 20 in at least one of the metrics could be considered as opinion leaders in obesity.

Conclusion

The analysis of the network of subject experts with media presence revealed that an opinion leader might have fewer mentions in the news articles, but a high network centrality measure and vice-versa. Betweenness, Closeness and Degree centrality measures were shown to supplement frequency counts in the task of finding subject experts. Further, opinion leaders missed in scientific publication network analysis could be retrieved from news articles.

The effect of a physician-targeted intervention on metoclopramide prescribing practice

Background

Metoclopramide use is associated with serious and potentially irreversible neurologic side effects. However, it is often used for questionable or unclear indications in clinical practice.

Objectives

To (1) determine whether an intervention targeted at the prescribing physician would increase the rate of metoclopramide discontinuation among patients prescribed the medication for questionable or unclear indications; and (2) assess the durability of the discontinuation.

Study design

A randomized controlled trial.

Setting

Ambulatory practices of a quaternary care medical center.

Participants

Ambulatory, electronic medical record-utilizing clinicians of the quaternary medical center.

Intervention

A letter regarding participating clinicians’ prescription(s) of metoclopramide for patients with questionable or unclear indications.

Main outcome measures

The rate and the durability of metoclopramide discontinuation.

Results

Fourteen of 31 (45%) patients of intervention group clinicians and 10 of 30 (33%) patients of nonintervention group clinicians had metoclopramide discontinued within 12 weeks, yielding a risk ratio for metoclopramide discontinuation of 1.4 (95% confidence interval [CI] 0.6–3.0) in the intervention versus nonintervention group. Of the 29 patients who had their metoclopramide discontinued during the study, 26 (90%, 95% CI 73%–98%) still had no active metoclopramide prescription in the subsequent 6 months. No adverse events were detected during the follow-up period.

Conclusion

A physician-targeted intervention letter did not lead to a statistically significantly increased rate of metoclopramide discontinuation among patients who had questionable or unclear indications for the medication. Discontinuation of metoclopramide therapy for questionable or unclear indications was durable in most patients.

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

BACKGROUND

Clinical practice is not always evidence-based and, therefore, may not optimise patient outcomes. Opinion leaders disseminating and implementing 'best evidence' is one method that holds promise as a strategy to bridge evidence-practice gaps.

OBJECTIVES

To assess the effectiveness of the use of local opinion leaders in improving professional practice and patient outcomes.

SEARCH STRATEGY

We searched Cochrane EPOC Group Trials Register, the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, HMIC, Science Citation Index, Social Science Citation Index, ISI Conference Proceedings and World Cat Dissertations up to 5 May 2009. In addition, we searched reference lists of included articles.

SELECTION CRITERIA

Studies eligible for inclusion were randomised controlled trials investigating the effectiveness of using opinion leaders to disseminate evidence-based practice and reporting objective measures of professional performance and/or health outcomes.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data from each study and assessed its risk of bias. For each trial, we calculated the median risk difference (RD) for compliance with desired practice, adjusting for baseline where data were available. We reported the median adjusted RD for each of the main comparisons.

MAIN RESULTS

We included 18 studies involving more than 296 hospitals and 318 PCPs. Fifteen studies (18 comparisons) contributed to the calculations of the median adjusted RD for the main comparisons. The effects of interventions varied across the 63 outcomes from 15% decrease in compliance to 72% increase in compliance with desired practice. The median adjusted RD for the main comparisons were: i) Opinion leaders compared to no intervention, +0.09; ii) Opinion leaders alone compared to a single intervention, +0.14; iii) Opinion leaders with one or more additional intervention(s) compared to the one or more additional intervention(s), +0.10; iv) Opinion leaders as part of multiple interventions compared to no intervention, +0.10. Overall, across all 18 studies the median adjusted RD was +0.12 representing a 12% absolute increase in compliance in the intervention group.

AUTHORS' CONCLUSIONS

Opinion leaders alone or in combination with other interventions may successfully promote evidence-based practice, but effectiveness varies both within and between studies. These results are based on heterogeneous studies differing in terms of type of intervention, setting, and outcomes measured. In most of the studies the role of the opinion leader was not clearly described, and it is therefore not possible to say what the best way is to optimise the effectiveness of opinion leaders.

Impact of multi-approach strategy on acid suppressive medication use in a teaching hospital in Qatar

OBJECTIVE

To evaluate the impact of a multi-approach strategy to improve the appropriate usage of acid suppressive medication (ASM) in medical inpatients and compare it with the baseline data from 2007.

SETTING

Five general medicine wards in a 600-bed teaching hospital in Doha, Qatar.

METHOD

A prospective evaluation of the usage of ASM 1 year after a multi-approach strategy. This consisted of four main interventions: audit and feedback method (including awareness lectures to all medical and pharmacy staff), implementation of a usage guideline for medical inpatients, circulating a logarithmic chart on the proper usage of ASM for medical inpatients from admission through to discharge and participation of clinical pharmacists in the multidisciplinary rounds. All medical patients admitted from May through June 2009 were evaluated. Data about the usage of ASM were collected upon and during admission, at discharge and at the next follow-up visit. Justified indications for its usage were based on the approved product information and on evidence-based literature recommendations. Data were compared with the findings of the baseline clinical audit done 2 years earlier.

MAIN OUTCOME MEASURE

The usage of ASM in justified and non-justified indications upon and during admission, at discharge and at the next follow up visit.

RESULTS

A total of 414 patients were admitted during the study period, 208 patients (50%) received ASM compared to 53% in 2007 (206 patients out of 389). Seventy-four patients (36%) were using ASM upon admission compared to 48 patients (23%) in the 2007 clinical audit. Inappropriate ASM use decreased with 51% during admission (66 to 32%, P < 0.0001), 62% at discharge (34 to 13%, P < 0.0001) and 67% at the next follow up visit (15 to 5%, P = 0.0008).

CONCLUSION

Despite the higher number of patients receiving ASM upon admission, the multi-approach strategy used in our institution resulted in a significant improvement in the appropriate usage of ASM in medical inpatients.

Improving cardiovascular health at population level: 39 community cluster randomised trial of Cardiovascular Health Awareness Program (CHAP)

OBJECTIVE

To evaluate the effectiveness of the community based Cardiovascular Health Awareness Program (CHAP) on morbidity from cardiovascular disease.

DESIGN

Community cluster randomised trial.

SETTING

39 mid-sized communities in Ontario, Canada, stratified by location and population size.

PARTICIPANTS

Community dwelling residents aged 65 years or over, family physicians, pharmacists, volunteers, community nurses, and local lead organisations.

INTERVENTION

Communities were randomised to receive CHAP (n = 20) or no intervention (n = 19). In CHAP communities, residents aged 65 or over were invited to attend volunteer run cardiovascular risk assessment and education sessions held in community based pharmacies over a 10 week period; automated blood pressure readings and self reported risk factor data were collected and shared with participants and their family physicians and pharmacists.

MAIN OUTCOME MEASURE

Composite of hospital admissions for acute myocardial infarction, stroke, and congestive heart failure among all community residents aged 65 and over in the year before compared with the year after implementation of CHAP.

RESULTS

All 20 intervention communities successfully implemented CHAP. A total of 1265 three hour long sessions were held in 129/145 (89%) pharmacies during the 10 week programme. 15,889 unique participants had a total of 27,358 cardiovascular assessments with the assistance of 577 peer volunteers. After adjustment for hospital admission rates in the year before the intervention, CHAP was associated with a 9% relative reduction in the composite end point (rate ratio 0.91, 95% confidence interval 0.86 to 0.97; P = 0.002) or 3.02 fewer annual hospital admissions for cardiovascular disease per 1000 people aged 65 and over. Statistically significant reductions favouring the intervention communities were seen in hospital admissions for acute myocardial infarction (rate ratio 0.87, 0.79 to 0.97; P = 0.008) and congestive heart failure (0.90, 0.81 to 0.99; P = 0.029) but not for stroke (0.99, 0.88 to 1.12; P = 0.89).

CONCLUSIONS

A collaborative, multi-pronged, community based health promotion and prevention programme targeted at older adults can reduce cardiovascular morbidity at the population level. Trial registration Current controlled trials ISRCTN50550004.

Collaborative quality improvement to manage pain in acute care hospitals

OBJECTIVE

Collaborative quality improvement programs have been successfully used to manage chronic diseases in adults and acute lung complications in premature infants. Their effectiveness to improve pain management in acute care hospitals is currently unknown. The purpose of this study was to determine whether a collaborative quality improvement program implemented at hospital level could improve pain management and overall pain relief.

DESIGN

To assess the effectiveness of the program, we performed a before-after trial comparing patient's self-reported pain management and experience before and after program implementation. We included all adult patients hospitalized for more than 24 hours and discharged either to their home or to a nursing facility, between March 1, 2001 and March 31, 2001 (before program implementation) and between September 15, 2005 and October 15, 2005 (after program implementation).

SETTING

A teaching hospital of 2,096 beds in Geneva, Switzerland.

PATIENTS

All adult patients hospitalized for more than 24 hours and discharged between 1 to 31 March 2001 (before program) and 15 September to 15 October 2005 (after program implementation).

INTERVENTIONS

Implementation of a collaborative quality improvement program using multifaceted interventions (staff education, opinion leaders, patient education, audit, and feedback) to improve pain management at hospital level.

OUTCOME MEASURES

Patient-reported pain experience, pain management, and overall hospital experience based on the Picker Patient Experience questionnaire, perceived health (SF-36 Health survey).

RESULTS

After implementation of the program only 2.3% of the patients reported having no pain relief during their hospital stay (vs 4.5% in 2001, P=0.05). Among nonsurgical patients, improvements were observed for pain assessment (42.3% vs 27.9% of the patients had pain intensity measured with a visual analog scale, P=0.012), pain management (staff did everything they could to help in 78.9% vs 67.9% of cases P=0.003), and pain relief (70.4% vs 57.3% of patients reported full pain relief P=0.008). In surgical patients, pain assessment also improved (53.7.3% vs 37.6%) as well as pain treatment. More patients received treatments to relieve pain regularly or intermittently after program implementation (95.1% vs 91.9% P=0.046).

CONCLUSION

Implementation of a collaborative quality improvement program at hospital level improved both pain management and pain relief in patients. Further studies are needed to determine the overall cost-effectiveness of such programs.

Toward the integration of education and mental health in schools

Education and mental health integration will be advanced when the goal of mental health includes effective schooling and the goal of effective schools includes the healthy functioning of students. To build a solid foundation for this reciprocal agenda, especially within the zeitgeist of recent educational reforms, a change in the fundamental framework within which school mental health is conceptualized is needed. This change involves acknowledging a new set of priorities, which include: the use of naturalistic resources within schools to implement and sustain effective supports for students' learning and emotional/behavioral health; inclusion of integrated models to enhance learning and promote health; attention to improving outcomes for all students, including those with serious emotional/behavioral needs; and strengthening the active involvement of parents. A strong research agenda to support these new priorities is essential.

The cluster-randomized Quality Initiative in Rectal Cancer trial: evaluating a quality-improvement strategy in surgery

BACKGROUND

Following surgery for rectal cancer, two unfortunate outcomes for patients are permanent colostomy and local recurrence of cancer. We tested whether a quality-improvement strategy to change surgical practice would improve these outcomes.

METHODS

Sixteen hospitals were cluster-randomized to the intervention (Quality Initiative in Rectal Cancer strategy) or control (normal practice) arm. Consecutive patients with primary rectal cancer were accrued from May 2002 to December 2004. Surgeons at hospitals in the intervention arm could voluntarily participate by attending workshops, using opinion leaders, inviting a study team surgeon to demonstrate optimal techniques of total mesorectal excision, completing postoperative questionnaires, and receiving audits and feedback. Main outcome measures were hospital rates of permanent colostomy and local recurrence of cancer.

RESULTS

A total of 56 surgeons (n = 558 patients) participated in the intervention arm and 49 surgeons (n = 457 patients) in the control arm. The median follow-up of patients was 3.6 years. In the intervention arm, 70% of surgeons participated in workshops, 70% in intraoperative demonstrations and 71% in postoperative questionnaires. Surgeons who had an intraoperative demonstration provided care to 86% of the patients in the intervention arm. The rates of permanent colostomy were 39% in the intervention arm and 41% in the control arm (odds ratio [OR] 0.97, 95% confidence interval [CI] 0.63-1.48). The rates of local recurrence were 7% in the intervention arm and 6% in the control arm (OR 1.06, 95% CI 0.68-1.64).

INTERPRETATION

Despite good participation by surgeons, the resource-intense quality-improvement strategy did not reduce hospital rates of permanent colostomy or local recurrence compared with usual practice.

Understanding uptake of continuous quality improvement in Indigenous primary health care: lessons from a multi-site case study of the Audit and Best Practice for Chronic Disease project

Background

Experimentation with continuous quality improvement (CQI) processes is well underway in Indigenous Australian primary health care. To date, little research into how health organizations take up, support, and embed these complex innovations is available on which services can draw to inform implementation. In this paper, we examine the practices and processes in the policy and organisational contexts, and aim to explore the ways in which they interact to support and/or hinder services' participation in a large scale Indigenous primary health care CQI program.

Methods

We took a theory-driven approach, drawing on literature on the theory and effectiveness of CQI systems and the Greenhalgh diffusion of innovation framework. Data included routinely collected regional and service profile data; uptake of tools and progress through the first CQI cycle, and data collected quarterly from hub coordinators on their perceptions of barriers and enablers. A total of 48 interviews were also conducted with key people involved in the development, dissemination, and implementation of the Audit and Best Practice for Chronic Disease (ABCD) project. We compiled the various data, conducted thematic analyses, and developed an in-depth narrative account of the processes of uptake and diffusion into services.

Results

Uptake of CQI was a complex and messy process that happened in fits and starts, was often characterised by conflicts and tensions, and was iterative, reactive, and transformational. Despite initial enthusiasm, the mixed successes during the first cycle were associated with the interaction of features of the environment, the service, the quality improvement process, and the stakeholders, which operated to produce a set of circumstances that either inhibited or enabled the process of change. Organisations had different levels of capacity to mobilize resources that could shift the balance toward supporting implementation. Different forms of leadership and organisational linkages were critical to success. The Greenhalgh framework provided a useful starting point for investigation, but we believe it is more a descriptive than explanatory model. As such, it has limitations in the extent to which it could assist us in understanding the interactions of the practices and processes that we observed at different levels of the system.

Summary

Taking up CQI involved engaging multiple stakeholders in new relationships that could support services to construct shared meaning and purpose, operationalise key concepts and tools, and develop and embed new practices into services systems and routines. Promoting quality improvement requires a system approach and organization-wide commitment. At the organization level, a formal high-level mandate, leadership at all levels, and resources to support implementation are needed. At the broader system level, governance arrangements that can fulfil a number of policy objectives related to articulating the linkages between CQI and other aspects of the regulatory, financing, and performance frameworks within the health system would help define a role and vision for quality improvement.

Evaluation of the sustainability of an intervention to increase HIV testing

BACKGROUND

Sustainability-the routinization and institutionalization of processes that improve the quality of healthcare-is difficult to achieve and not often studied.

OBJECTIVE

To evaluate the sustainability of increased rates of HIV testing after implementation of a multi-component intervention in two Veterans Health Administration healthcare systems.

DESIGN

Quasi-experimental implementation study in which the effect of transferring responsibility to conduct the provider education component of the intervention from research to operational staff was assessed.

PATIENTS

Persons receiving healthcare between 2005 and 2006 (intervention year) and 2006 and 2007 (sustainability year).

MEASUREMENTS

Monthly HIV testing rate, stratified by frequency of clinic visits.

RESULTS

The monthly adjusted testing rate increased from 2% at baseline to 6% at the end intervention year and then declined reaching 4% at the end of the sustainability year. However, the stratified, visit-specific testing rate for persons newly exposed to the intervention (i.e., having their first through third visits during the study period) increased throughout the intervention and sustainability years. Increases in the proportion of visits by patients who remained untested despite multiple, prior exposures to the intervention accounted for the aggregate attenuation of testing during the sustainability year. Overall, the percentage of patients who received an HIV test in the sustainability year was 11.6%, in the intervention year 11.1%, and in the pre-intervention year 5.0%

CONCLUSIONS

Provider education combined with informatics and organizational support had a sustainable effect on HIV testing rates. The effect was most pronounced during patients' early contacts with the healthcare system.

Effectiveness of strategies to encourage general practitioners to accept an offer of free access to online evidence-based information: a randomised controlled trial

Background

This study examined the effectiveness of seven different interventions designed to increase the proportion of general practitioners (GPs) accepting an offer of free access to an online evidence-based resource.

Methods

Australian GPs (n = 14,000) were randomly selected and assigned to seven intervention groups, with each receiving a different letter. Seven different strategies were used to encourage GPs to accept an offer of two years free access to an online evidence-based resource (BMJ Clinical Evidence). The first group received a standard letter of offer with no experimental demands. Groups two to seven received a standard letter of offer outlining the requirements of the study. They were asked to complete an initial online questionnaire, agree to complete a 12-month follow-up questionnaire, and agree to having data about their usage of the online evidence-based resource provided to researchers. Groups three to seven also had additional interventions included in the letter of offer: access to an online tutorial in use of the resource (group three); provision of a pamphlet with statements from influential opinion leaders endorsing the resource (group four); offer of eligibility to receive professional development points (group five); offer of eligibility for a prize of $500 for registration at a medical conference of their choice (group six); and a combination of some of the above interventions (group seven).

Results

In the group with no research demands, 27% accepted the offer. Average acceptance across all other groups was 10%. There was no advantage in using additional strategies such as financial incentives, opinion leader support, offer of professional development points, or an educational aid over a standard letter of offer to increase acceptance rates.

Conclusion

This study showed low acceptance rates of the offer of access to the online resource when there was an associated requirement of response to a short online questionnaire and non-obtrusive monitoring of GP behaviour in terms of accessing the resource. If we are to improve care and encourage evidence-based practice, we need to find effective ways of motivating doctors and other health professionals to take part in research that can inform our implementation efforts.

Study protocol for the translating research in elder care (TREC): building context - an organizational monitoring program in long-term care project (project one)

Background

While there is a growing awareness of the importance of organizational context (or the work environment/setting) to successful knowledge translation, and successful knowledge translation to better patient, provider (staff), and system outcomes, little empirical evidence supports these assumptions. Further, little is known about the factors that enhance knowledge translation and better outcomes in residential long-term care facilities, where care has been shown to be suboptimal. The project described in this protocol is one of the two main projects of the larger five-year Translating Research in Elder Care (TREC) program.

Aims

The purpose of this project is to establish the magnitude of the effect of organizational context on knowledge translation, and subsequently on resident, staff (unregulated, regulated, and managerial) and system outcomes in long-term care facilities in the three Canadian Prairie Provinces (Alberta, Saskatchewan, Manitoba).

Methods/Design

This study protocol describes the details of a multi-level – including provinces, regions, facilities, units within facilities, and individuals who receive care (residents) or work (staff) in facilities – and longitudinal (five-year) research project. A stratified random sample of 36 residential long-term care facilities (30 urban and 6 rural) from the Canadian Prairie Provinces will comprise the sample. Caregivers and care managers within these facilities will be asked to complete the TREC survey – a suite of survey instruments designed to assess organizational context and related factors hypothesized to be important to successful knowledge translation and to achieving better resident, staff, and system outcomes. Facility and unit level data will be collected using standardized data collection forms, and resident outcomes using the Resident Assessment Instrument-Minimum Data Set version 2.0 instrument. A variety of analytic techniques will be employed including descriptive analyses, psychometric analyses, multi-level modeling, and mixed-method analyses.

Discussion

Three key challenging areas associated with conducting this project are discussed: sampling, participant recruitment, and sample retention; survey administration (with unregulated caregivers); and the provision of a stable set of study definitions to guide the project.

Getting clinical trial results into practice: design, implementation, and process evaluation of the ALLHAT Dissemination Project

BACKGROUND

Conventional dissemination of clinical trial results has inconsistent impact on physician practices. A more comprehensive plan to influence determinants of prescribing practices is warranted.

PURPOSE

To report the response from the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial to the National Heart, Lung, and Blood Institute's requirement for dissemination and evaluation of trials with potential immediate public health applicability.

METHODS

ALLHAT's dissemination plan had two-components: (1) a traditional approach of media coverage, scientific presentation, and publication; and (2) a theory-based approach targeting determinants of clinician behavior. Strategies included: (1) academic detailing, in which physicians approach colleagues regarding blood pressure management, (2) direct patient messages to stimulate communication with physicians regarding blood pressure control, (3) approaches to formulary systems to use educational and economic incentives for evidence-based prescription, and (4) direct professional organization appeals to clinicians.

RESULTS

One hundred and forty-seven Investigator Educators reported 1698 presentations to 18,524 clinicians in 41 states and the District of Columbia. The pre- and post-test responses of 1709 clinicians in the face-to-face meetings indicated significant changes in expectations for positive patient outcomes and intention to prescribe diuretics. Information was mailed to 55 individuals representing 20 professional organizations and to eight formulary systems. Direct-to-patient messages were provided to 14 sites that host patient newsletters and Web sites such as health plans and insurance companies, 62 print mass media outlets, and 12 broadcast media sites.

LIMITATIONS

It was not within the scope of the project to conduct a randomized trial of the impact of the dissemination. However, impact evaluation using quasi-experimental designs is ongoing.

CONCLUSION

A large multi-method dissemination of clinical trial results is feasible. Planning for dissemination efforts, including evaluation research, should be considered as a part of the funding and design of the clinical trial and should begin early in trial planning.

Quality improvement in small office settings: an examination of successful practices

Background

Physicians in small to moderate primary care practices in the United States (U.S.) (<25 physicians) face unique challenges in implementing quality improvement (QI) initiatives, including limited resources, small staffs, and inadequate information technology systems 23,36. This qualitative study sought to identify and understand the characteristics and organizational cultures of physicians working in smaller practices who are actively engaged in measurement and quality improvement initiatives.

Methods

We undertook a qualitative study, based on semi-structured, open-ended interviews conducted with practices (N = 39) that used performance data to drive quality improvement activities.

Results

Physicians indicated that benefits to performing measurement and QI included greater practice efficiency, patient and staff retention, and higher staff and clinician satisfaction with practice. Internal facilitators included the designation of a practice champion, cooperation of other physicians and staff, and the involvement of practice leaders. Time constraints, cost of activities, problems with information management and or technology, lack of motivated staff, and a lack of financial incentives were commonly reported as barriers.

Conclusion

These findings shed light on how physicians engage in quality improvement activities, and may help raise awareness of and aid in the implementation of future initiatives in small practices more generally.

An evaluation of educational outreach to improve evidence-based prescribing in Medicaid: a cautionary tale

RATIONALE, AIMS AND OBJECTIVES

Evidence suggests that educational outreach ('academic detailing') improves evidence-based prescribing. We evaluated the impact of an academic detailing programme intended to increase new statin prescriptions.

METHODS

In a 2 x 2 factorial design we evaluated the effect of an academic detailing programme with/without telephonic care management for patients. Eligible patients were continuously enrolled Medicaid members at high risk for cardiovascular disease utilization who were not receiving statin medication in the 18 months prior to the intervention. All primary care prescribers assigned to these patients were randomized by clinic to academic detailing. Two trained nurses provided the detailing to prescribers, including specific discussion about the use of statins in this high-risk patient population. Nurses left the prescribers with a summary of clinical practice guidelines, a one-page detailing sheet and a list of patients under the care of the prescriber who were candidates for statins. The primary outcome was the incidence of a new statin prescription claim during the 6-month intervention period and the subsequent 6 months. Logistic regression models were used to estimate main effects of the interventions and to adjust for potential confounding variables in the study.

RESULTS

Forty-eight clinics were randomized, effectively randomizing a total of 284 patients and 128 prescribers. Among the 284 patients, 46 (16%) received a new statin claim during the evaluation period. Controlling for significant bivariate associations, the academic detailing intervention had no significant effect on new statin prescriptions compared with the control group (odds ratio = 0.8, 95% confidence interval: 0.4-1.6, P = 0.5).

CONCLUSION

Among this Medicaid population at high risk for cardiovascular events, an academic detailing programme to increase statin prescriptions was not effective. To assist others to learn from our failed effort, we identify and discuss critical elements in the design and implementation of the programme that could account for these results.

A system-wide intervention to improve HIV testing in the Veterans Health Administration

BACKGROUND

Although the benefits of identifying and treating asymptomatic HIV-infected individuals are firmly established, health care providers often miss opportunities to offer HIV-testing.

OBJECTIVE

To evaluate whether a multi-component intervention increases the rate of HIV diagnostic testing.

DESIGN

Pre- to post-quasi-experiment in 5 Veterans Health Administration facilities. Two facilities received the intervention; the other three facilities were controls. The intervention included a real-time electronic clinical reminder that encourages HIV testing, and feedback reports and a provider activation program.

PATIENTS

Persons receiving health care between August 2004 and September 2006 who were at risk but had not been previously tested for HIV infection.

MEASUREMENTS

Pre- to post-changes in the rates of HIV testing at the intervention and control facilities

RESULTS

At the two intervention sites, the adjusted rate of testing increased from 4.8% to 10.8% and from 5.5% to 12.8% (both comparisons, p < .001). In addition, there were 15 new diagnoses of HIV in the pre-intervention year (0.46% of all tests) versus 30 new diagnoses in the post-intervention year (0.45% of all tests). No changes were observed at the control facilities.

CONCLUSIONS

Use of clinical reminders and provider feedback, activation, and social marketing increased the frequency of HIV testing and the number of new HIV diagnoses. These findings support a multimodal approach toward achieving the Centers for Disease Control and Prevention's goal of having every American know their HIV status as a matter of routine clinical practice.

Interventions designed to improve the quality and efficiency of medication use in managed care: a critical review of the literature - 2001-2007

Background

Managed care organizations use a variety of strategies to reduce the cost and improve the quality of medication use. The effectiveness of such policies is not well understood. The objective of this research was to update a previous systematic review of interventions, published between 1966 and 2001, to improve the quality and efficiency of medication use in the US managed care setting.

Methods

We searched MEDLINE and EMBASE for publications from July 2001 to January 2007 describing interventions targeting drug use conducted in the US managed care setting. We categorized studies by intervention type and adequacy of research design using commonly accepted criteria. We summarized the outcomes of well-controlled strategies and documented the significance and magnitude of effects for key study outcomes.

Results

We identified 164 papers published during the six-year period. Predominant strategies were: educational interventions (n = 20, including dissemination of educational materials, and group or one-to-one educational outreach); monitoring and feedback (n = 22, including audit/feedback and computerized monitoring); formulary interventions (n = 66, including tiered formulary and patient copayment); collaborative care involving pharmacists (n = 15); and disease management with pharmacotherapy as a primary focus (n = 41, including care for depression, asthma, and peptic ulcer disease). Overall, 51 studies met minimum criteria for methodological adequacy. Effective interventions included one-to-one academic detailing, computerized alerts and reminders, pharmacist-led collaborative care, and multifaceted disease management. Further, changes in formulary tier-design and related increases in copayments were associated with reductions in medication use and increased out-of-pocket spending by patients. The dissemination of educational materials alone had little or no impact, while the impact of group education was inconclusive.

Conclusion

There is good evidence for the effectiveness of several strategies in changing drug use in the managed care environment. However, little is known about the cost-effectiveness of these interventions. Computerized alerts showed promise in improving short-term outcomes but little is known about longer-term outcomes. Few well-designed, published studies have assessed the potential negative clinical effects of formulary-related interventions despite their widespread use. However, some evidence suggests increases in cost sharing reduce access to essential medicines for chronic illness.

Implementing and evaluating a regional strategy to improve testing rates in VA patients at risk for HIV, utilizing the QUERI process as a guiding framework: QUERI Series

BACKGROUND

We describe how we used the framework of the U.S. Department of Veterans Affairs (VA) Quality Enhancement Research Initiative (QUERI) to develop a program to improve rates of diagnostic testing for the Human Immunodeficiency Virus (HIV). This venture was prompted by the observation by the CDC that 25% of HIV-infected patients do not know their diagnosis - a point of substantial importance to the VA, which is the largest provider of HIV care in the United States.

METHODS

Following the QUERI steps (or process), we evaluated: 1) whether undiagnosed HIV infection is a high-risk, high-volume clinical issue within the VA, 2) whether there are evidence-based recommendations for HIV testing, 3) whether there are gaps in the performance of VA HIV testing, and 4) the barriers and facilitators to improving current practice in the VA.Based on our findings, we developed and initiated a QUERI step 4/phase 1 pilot project using the precepts of the Chronic Care Model. Our improvement strategy relies upon electronic clinical reminders to provide decision support; audit/feedback as a clinical information system, and appropriate changes in delivery system design. These activities are complemented by academic detailing and social marketing interventions to achieve provider activation.

RESULTS

Our preliminary formative evaluation indicates the need to ensure leadership and team buy-in, address facility-specific barriers, refine the reminder, and address factors that contribute to inter-clinic variances in HIV testing rates. Preliminary unadjusted data from the first seven months of our program show 3-5 fold increases in the proportion of at-risk patients who are offered HIV testing at the VA sites (stations) where the pilot project has been undertaken; no change was seen at control stations.

DISCUSSION

This project demonstrates the early success of the application of the QUERI process to the development of a program to improve HIV testing rates. Preliminary unadjusted results show that the coordinated use of audit/feedback, provider activation, and organizational change can increase HIV testing rates for at-risk patients. We are refining our program prior to extending our work to a small-scale, multi-site evaluation (QUERI step 4/phase 2). We also plan to evaluate the durability/sustainability of the intervention effect, the costs of HIV testing, and the number of newly identified HIV-infected patients. Ultimately, we will evaluate this program in other geographically dispersed stations (QUERI step 4/phases 3 and 4).

The Quality Initiative in Rectal Cancer (QIRC) trial: study protocol of a cluster randomized controlled trial in surgery

BACKGROUND

Two unfortunate outcomes for patients treated surgically for rectal cancer are placement of a permanent colostomy and local tumor recurrence. Total mesorectal excision is a new technique for rectal cancer surgery that can lead to improved patient outcomes. We describe a cluster randomized controlled trial that is testing if the above patient outcomes can be improved through a knowledge translation strategy called the Quality Initiative in Rectal Cancer (QIRC) strategy. The strategy is designed to optimize the use of total mesorectal excision techniques.

METHODS AND DESIGN

Hospitals were randomized to the QIRC strategy (experimental group) versus normal practice environment (control group). Participating hospitals, and the respective surgeon group operating in them, are from Ontario, Canada and have an annual procedure volume for major rectal cancer resections of 15 or greater. Patients were eligible if they underwent major rectal surgery for a diagnosis of primary rectal cancer. The surgeon-directed QIRC interventions included a workshop, use of opinion leaders, operative demonstrations, a post-operative questionnaire, and, audit and feedback. For an operative demonstration participating surgeons invited a study team surgeon to assist them with a case of rectal cancer surgery. The intent was to demonstrate total mesorectal excision techniques. Control arm surgeons received no intervention. Sample size calculations were two-sided, considered the clustering of data at the hospital level, and were driven by requirements for the outcome local recurrence. To detect an improvement in local recurrence from 20% to 8% with confidence we required 16 hospitals and 672 patients - 8 hospitals and 336 patients in each arm. Outcomes data are collected via chart review for at least 30 months after surgery. Analyses will use an intention-to-treat principle and will consider the clustering of data. Data collection will be complete by the end of 2007.

DISCUSSION

Lower rates of permanent colostomy and local tumour recurrence in the intervention arm would suggest the QIRC strategy is efficacious. The strategy may act as a template for efforts to improve surgical quality in other areas and will contribute to knowledge on influencing surgeon practice.

The BLISS cluster randomised controlled trial of the effect of 'active dissemination of information' on standards of care for premature babies in England (BEADI) study protocol [ISRCTN89683698]

Background

Gaps between research knowledge and practice have been consistently reported. Traditional ways of communicating information have limited impact on practice changes. Strategies to disseminate information need to be more interactive and based on techniques reported in systematic reviews of implementation of changes. There is a need for clarification as to which dissemination strategies work best to translate evidence into practice in neonatal units across England. The objective of this trial is to assess whether an innovative active strategy for the dissemination of neonatal research findings, recommendations, and national neonatal guidelines is more likely to lead to changes in policy and practice than the traditional (more passive) forms of dissemination in England.

Methods/design

Cluster randomised controlled trial of all neonatal units in England (randomised by hospital, n = 182 and stratified by neonatal regional networks and neonatal units level of care) to assess the relative effectiveness of active dissemination strategies on changes in local policies and practices. Participants will be mainly consultant lead clinicians in each unit. The intervention will be multifaceted using: audit and feedback; educational meetings for local staff (evidence-based lectures on selected topics, interactive workshop to examine current practice and draw up plans for change); and quality improvement and organisational changes methods. Policies and practice outcomes for the babies involved will be collected before and after the intervention. Outcomes will assess all premature babies born in England during a three month period for timing of surfactant administration at birth, temperature control at birth, and resuscitation team (qualification and numbers) present at birth.

Taking stock of current societal, political and academic stakeholders in the Canadian healthcare knowledge translation agenda

Background

In the past 15 years, knowledge translation in healthcare has emerged as a multifaceted and complex agenda. Theoretical and polemical discussions, the development of a science to study and measure the effects of translating research evidence into healthcare, and the role of key stakeholders including academe, healthcare decision-makers, the public, and government funding bodies have brought scholarly, organizational, social, and political dimensions to the agenda.

Objective

This paper discusses the current knowledge translation agenda in Canadian healthcare and how elements in this agenda shape the discovery and translation of health knowledge.

Discussion

The current knowledge translation agenda in Canadian healthcare involves the influence of values, priorities, and people; stakes which greatly shape the discovery of research knowledge and how it is or is not instituted in healthcare delivery. As this agenda continues to take shape and direction, ensuring that it is accountable for its influences is essential and should be at the forefront of concern to the Canadian public and healthcare community. This transparency will allow for scrutiny, debate, and improvements in health knowledge discovery and health services delivery.

Effectiveness of a practice-based, multimodal quality improvement intervention for gastroenteritis within a Medicaid managed care network

OBJECTIVE

Acute gastroenteritis results in 220,000 hospitalizations yearly in the United States. The substantial geographic variation in gastroenteritis care, coupled with the evidence of effective treatment of dehydration in nonhospital settings, suggests that the majority of these hospitalizations are avoidable. We sought to decrease hospitalizations for gastroenteritis by using practice-based, multimodal quality improvement methods that target multiple care processes to make them consistent with evidence-based guidelines.

METHODS

We used a controlled before/after study design to evaluate a quality improvement intervention in a 20-practice Medicaid network. All 20 practices participated in continuing education sessions; received free oral rehydration solution, patient education materials, and performance feedback; and participated in a follow-up conference call. Three practices were chosen to develop and pilot office-process changes. These practices formed interdisciplinary teams to develop and test changes and collaborated with project faculty and each other. They shared their learning with the other 17 practices via a conference call and toolkit. We compared before/after gastroenteritis hospital admissions for children <5 years old covered by Medicaid in the intervention practices with all other Medicaid recipients in North Carolina using claims data from 2000-2002.

RESULTS

The 3 high-intensity practices all made numerous changes to care processes. Most of the 17 low-intensity practices reported changes in their gastroenteritis care processes. Gastroenteritis admission rates declined 45% in high-intensity practices and 44% in low-intensity practices during the study compared with 11% in the control practices.

CONCLUSIONS

A practice-based, multimodal quality improvement intervention that targets multiple care processes on the basis of evidence-based guidelines lowered rates of gastroenteritis hospitalization in a Medicaid network. This approach could lower costs attributable to gastroenteritis for Medicaid programs.

Impact of consensus development conference guidelines on primary care of bronchiolitis: are national guidelines being followed?

AIM

To measure the impact of French national consensus guidelines on the clinical practices of primary care paediatricians and general practitioners.

DESIGN

Non-randomized intervention study, with a first survey 1 year before the consensus development conference and a second survey 1 year after.

INTERVENTION

Implementation of bronchiolitis management guidelines through the medical press and the Internet.

SUBJECTS

Paediatricians and general practitioners treating infants 1 year of age and under consulting for a first-time episode of bronchiolitis.

RESULTS

Ninety-three doctors and 510 infants were included during the first phase of the study and 96 doctors and 394 infants during the second phase. This study showed a slight increase in adherence to the guidelines for non-validated drugs (6.6% adherence before and 14.3% after), general advice (29.0% adherence before and 57.1% after) and flow modulation respiratory physical therapy (91.9% adherence before and 98.8% after). Increase in adherence to guidelines for other practices, that is, hospitalization, prescribing antibiotics and complementary examinations, was not statistically significant. Adherence to the guidelines on providing general advice increased the most between the two studies.

CONCLUSION

The guidelines helped practitioners evolve slightly in their approach to the treatment of bronchiolitis. Non-validated drugs remain frequently used. Additional resources for implementing the guidelines should be provided to improve primary care doctors' practices.

Do clinical guidelines enhance safe practice in obstetrics and gynaecology?

Clinical guidelines are increasingly used to promote a more uniform standard of high-quality evidence-based health care. International agencies advocate guideline development methods founded on three principles: that recommendations are evidence-based, are explicitly linked to the type and quality of evidence, and are developed by multidisciplinary stakeholder groups. Numerous interventions have been described to support the implementation of guidelines. Systematic reviews suggest that most interventions produce modest to moderate improvements in care; multifaceted interventions appear to be no more effective than single interventions, and the lowest-cost implementation strategy (dissemination of printed materials) may improve care and be feasible in many settings. Given the considerable costs of developing valid guidelines de novo, we advocate local adaptation of existing guidelines if available. We suggest a pragmatic framework to assist policy-makers and clinicians in deciding how best to use the scarce resources available for quality-improvement activities.

Assessing organisational readiness for change: use of diagnostic analysis prior to the implementation of a multidisciplinary assessment for acute stroke care

BACKGROUND

Achieving evidence-based practice in health care is integral to the drive for quality improvement in the National Health Service in the UK. Encapsulated within this policy agenda are challenges inherent in leading and managing organisational change. Not least of these is the need to change the behaviours of individuals and groups in order to embed new practices. Such changes are set within a context of organisational culture that can present a number of barriers and facilitators to change. Diagnostic analysis has been recommended as a precursor to the implementation of change to enable such barriers and facilitators to be identified and a targeted implementation strategy developed. Although diagnostic analysis is recommended, there is a paucity of advice on appropriate methods to use. This paper addresses the paucity and builds on previous work by recommending a mixed method approach to diagnostic analysis comprising both quantitative and qualitative data.

METHODS

Twenty staff members with strategic accountability for stroke care were purposively sampled to take part in semi-structured interviews. Six recently discharged patients were also interviewed. Focus groups were conducted with one group of registered ward-based nurses (n = 5) and three specialist registrars (n = 3) purposively selected for their interest in stroke care. All professional staff on the study wards were sent the Team Climate Inventory questionnaire (n = 206). This elicited a response rate of 72% (n = 148).

RESULTS

A number of facilitators for change were identified, including stakeholder support, organisational commitment to education, strong team climate in some teams, exemplars of past successful organisational change, and positive working environments. A number of barriers were also identified, including: unidisciplinary assessment/recording practices, varying in structure and evidence-base; weak team climate in some teams; negative exemplars of organisational change; and uncertainty created by impending organisational merger.

CONCLUSION

This study built on previous research by proposing a mixed method approach for diagnostic analysis. The combination of qualitative and quantitative data were able to capture multiple perspectives on barriers and facilitators to change. These data informed the tailoring of the implementation strategy to the specific needs of the Trust.

Bridging the knowledge-resuscitation gap for children: Still a long way to go

The American Heart Association, along with the International Liaison Committee on Resuscitation, recently made changes to the paediatric resuscitation guidelines.Knowledge translation (KT) is imperative, but there is a lack of sufficient evidence for appropriate methodologies for implementation of these guidelines. Paediatric resuscitation presents many challenges; cases happen infrequently, affording few opportunities for implementation of the new guidelines, and are highly stressful and filled with uncertainty. Some KT strategies have shown some success in causing a notable degree of change in behaviour, but none have shown a striking difference when used alone.Previous efforts to disseminate current guidelines centred on development of courses for health care providers and preparing paediatric residents and paediatricians for circumstances they could encounter with paediatric acute illness. None of the studies assessing these techniques measured direct patient outcomes, and only a few demonstrated some long-term knowledge acquisition among trainees. The purpose of the present review was to illuminate the challenges, offer future directions for KT and outline potentially more effective methodologies and strategies to overcome current barriers.

Improving the management of acute coronary syndromes in Australia: translating evidence to outcomes

Cardiovascular disease imposes a heavy burden of morbidity and mortality on the Australian community. This situation is likely to exacerbate as the number of elderly Australians increase. Management of acute coronary syndromes (ACS) is underpinned by a robust evidence base, which is outlined in clinical practice guidelines. Yet, despite wide diffusion of guidelines, many Australians who experience acute coronary syndromes do not receive optimal care. This article reviews what we have learnt from previous quality improvement initiatives and discusses what we need to know to improve acute coronary syndromes management in Australia.

Clinical practice guideline implementation strategy patterns in Veterans Affairs primary care clinics

BACKGROUND

The Department of Veterans Affairs (VA) mandated the system-wide implementation of clinical practice guidelines (CPGs) in the mid-1990s, arming all facilities with basic resources to facilitate implementation; despite this resource allocation, significant variability still exists across VA facilities in implementation success.

OBJECTIVE

This study compares CPG implementation strategy patterns used by high and low performing primary care clinics in the VA.

RESEARCH DESIGN

Descriptive, cross-sectional study of a purposeful sample of six Veterans Affairs Medical Centers (VAMCs) with high and low performance on six CPGs.

SUBJECTS

One hundred and two employees (management, quality improvement, clinic personnel) involved with guideline implementation at each VAMC primary care clinic. MEASURES; Participants reported specific strategies used by their facility to implement guidelines in 1-hour semi-structured interviews. Facilities were classified as high or low performers based on their guideline adherence scores calculated through independently conducted chart reviews.

FINDINGS

High performing facilities (HPFs) (a) invested significantly in the implementation of the electronic medical record and locally adapting it to provider needs, (b) invested dedicated resources to guideline-related initiatives, and (c) exhibited a clear direction in their strategy choices. Low performing facilities exhibited (a) earlier stages of development for their electronic medical record, (b) reliance on preexisting resources for guideline implementation, with little local adaptation, and (c) no clear direction in their strategy choices.

CONCLUSION

A multifaceted, yet targeted, strategic approach to guideline implementation emphasizing dedicated resources and local adaptation may result in more successful implementation and higher guideline adherence than relying on standardized resources and taxing preexisting channels.

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

BACKGROUND

Clinical practice is not always evidence-based and, therefore, may not optimise patient outcomes. Opinion leaders disseminating and implementing 'best evidence' is one innovative method that holds promise as a strategy to bridge evidence-practice gaps.

OBJECTIVES

To assess the effectiveness of the use of local opinion leaders in improving the behaviour of health care professionals and patient outcomes.

SEARCH STRATEGY

We searched MEDLINE, Health Star, SIGLE and the Cochrane Effective Practice and Organisation of Care Group Trials Register. We did not apply date restrictions to our search strategy. Searches were last updated in February 2005. In addition, we searched reference lists of all potential studies that were identified.

SELECTION CRITERIA

Studies eligible for inclusion were randomized controlled trials that used objective measures of performance/provider behaviour and/or patient health outcomes.

DATA COLLECTION AND ANALYSIS

Two reviewers extracted data from each study and assessed its methodological quality. We calculated the absolute difference in the risk of 'non-compliance' with desired practice, adjusting for baseline levels of non-compliance where these data were available.

MAIN RESULTS

Twelve studies met our eligibility criteria. The adjusted absolute risk difference of non-compliance with desired practice varied from -6% (favouring control) to +25% (favouring opinion leader intervention). Overall, the median adjusted risk difference (ARD) was 0.10 representing a 10% absolute decrease in non-compliance in the intervention group.

AUTHORS' CONCLUSIONS

The use of local opinion leaders can successfully promote evidence-based practice. However the feasibility of its widespread use remains uncertain.

Planning and studying improvement in patient care: the use of theoretical perspectives

A consistent finding in articles on quality improvement in health care is that change is difficult to achieve. According to the research literature, the majority of interventions are targeted at health care professionals. But success in achieving change may be influenced by factors other than those relating to individual professionals, and theories may help explain whether change is possible. This article argues for a more systematic use of theories in planning and evaluating quality-improvement interventions in clinical practice. It demonstrates how different theories can be used to generate testable hypotheses regarding factors that influence the implementation of change, and it shows how different theoretical assumptions lead to different quality-improvement strategies.
