Interventions to change the behaviour of health professionals and the organisation of care to promote weight reduction in overweight and obese people

Development of a telehealth obesity OSCE and reliable checklist for assessment of resident physicians: a pilot study

BACKGROUND

Obesity is a major public health problem, yet residents undergo little formal training and assessment in obesity-related care. Given the recent growth of telehealth, physicians must further learn to apply these skills using a virtual platform. Therefore, we aimed to develop an objective structured clinical examination (OSCE) with reliable checklists to assess resident ability to take a patient-centered obesity-focused history that was feasible over telehealth based on published obesity competencies for medical education.

METHODS

We developed a 15-minute telehealth OSCE to simulate an obesity-related encounter for residents modified from a script used to assess medical student obesity competencies. We designed three checklists to assess resident skills in history taking, communication and professionalism during the obesity-related encounter. Resident performance was assessed as the percentage of obesity-related history taking questions asked during the encounter and as the mean communication and professionalism scores on a scale of 1 through 5 with 1 representing unacceptable/offensive behavior and 5 representing excellent skills. Encounters and assessments were completed by two commissioned actors (standardized patients) and 26 internal medicine residents over a secure online platform. We assessed the reliability of each checklist by calculating the percent agreement between standardized patients and the kappa (κ) statistic on each checklist overall and by each checklist item.

RESULTS

Overall agreement between standardized patients on the history taking, communication and professionalism checklists were 83.2% (κ = 0.63), 99.5% (κ = 0.72) and 97.8% (κ =0.44), respectively. On average, residents asked 64.8% of questions on the history taking checklist and scored 3.8 and 3.9 out of 5 on the communication and professionalism checklists, respectively.

CONCLUSIONS

Results from this pilot study suggest that our telehealth obesity OSCE and checklists are moderately reliable for assessing key obesity competencies among residents on a virtual platform. Integrating obesity OSCEs and other educational interventions into residency curricula are needed to improve resident ability to take an obesity-focused history.

Using Novel Implementation Tools for Evidence-based Intervention Delivery (UNITED) across public service systems for three evidence-based autism interventions in under-resourced communities: study protocol

BACKGROUND

There are a growing number of evidence-based interventions (EBIs) for autistic individuals, but few are successfully implemented with fidelity in under-resourced communities and with families from traditionally disenfranchised groups. Implementation science offers tools to increase EBI use in communities, but most implementation strategies are designed specific to a single EBI. It is not feasible to develop a new implementation strategy each time a new EBI is introduced in the community. Therefore, to test the effectiveness and generalizability of implementation strategies we are developing and testing a multifaceted implementation strategy with three EBIs concurrently. The goal of this protocol paper is to describe the randomized field trial of an implementation strategy for use across autism EBIs, diverse settings and participants, with the goal of increasing rapid uptake of effective practices to reach our most vulnerable children.

METHODS

We developed a multifaceted implementation strategy called Using Novel Implementation Tools for Evidence-based intervention Delivery (UNITED) to facilitate the implementation and sustainment of three EBIs in under-resourced settings. We will compare fidelity to, and effectiveness of, each intervention [Mind the Gap (MTG), Remaking Recess (RR), Self-Determined Learning Model of Instruction (SDLMI)] with and without UNITED in a randomized field trial. Randomization will be stratified using a minimization allocation method. We will train community practitioners using remote delivery of modules specific to the intervention, and active coaching via Zoom for at least 6 sessions and up to 12 as dictated by each EBI. Our primary outcome is fidelity to each EBI, and our secondary outcome is at the child or family level (family empowerment for MTG, child peer social engagement for RR, and adolescent self-determination for SDLMI, respectively). We will measure progress through the implementation phases using the Stages of Implementation Completion and cost-effectiveness of UNITED.

DISCUSSION

The results of this study will provide rigorous data on the effectiveness and generalizability of one relatively light-touch implementation strategy in increasing use of autism EBIs and associated outcomes in diverse under resourced public service settings for underrepresented autistic youth.

Coalition-Committees as Network Interventions: Baseline Network Composition in Context of Childhood Obesity Prevention Interventions

Community coalitions can address local issues with deep, historic, and contextual understanding that enables customized implementation of evidence-based strategies. The individuals within the coalition, their partnerships, and the social context is likely an important component of unraveling the challenges of implementation so interventions reach people in need. We focus on the relevance of baseline coalition-committee network (CCN), the networks of purposely formed subcommittees within community coalitions, structure as one of the moderating, theoretical links between community coalition social networks and intervention success. We explore the baseline composition and characteristics of five CCNs at the beginning of childhood obesity prevention interventions. Using a combination of social network, multidimensional scaling, and correspondence analyses, we examine the structure and heterogeneity of five CCNs, each consisting of a core group of stakeholders in the coalition and sometimes the broader community itself. Cross-sectional analyses are used to examine the composition of coalition-committees related to network density, centralization, hierarchy, and coalition demographics and characteristics. Results indicate that CCNs are patterned in their structure and characteristics, and we discuss whether adjustments to childhood obesity prevention interventions according to baseline structure and characteristics could be advantageous for intervention implementation. Together, these findings can inform future longitudinal investigations into CCN network structure.

Evaluation of a Pediatric Obesity Management Toolkit for Health Care Professionals: A Quasi-Experimental Study

Health care professionals (HCPs) play a critical role in helping to address weight-related issues with pediatric patients, yet often feel ill-equipped to discuss/manage this complex and sensitive health issue. Using the five As ("Ask, Assess, Advise, Agree, and Assist") of Pediatric Obesity Management, we created a series of educational videos and evaluated the content, quality (acceptability, engagement), and impact of these videos on HCPs' self-efficacy, knowledge, and change in practice when addressing weight-related issues with pediatric patients and their families using questionnaires. HCPs (n = 65) participated in a baseline assessment and 4-6 month follow-up (n = 54). Knowledge and self-efficacy increased post-video for the majority of participants. At follow-up, most HCPs reported a change in their practice attributable to viewing the videos, and their self-efficacy ratings improved over time for the majority of questions asked. Most participants rated aspects of each of the videos highly. Preliminary findings suggest that an evidence-based educational toolkit of videos, based on the 5As framework, may lead to changes in self-reported behaviors among HCPs, and sustained improvements in their self-efficacy in addressing weight-related topics with children and their families.

SUMAMOS EXCELENCIA® Project: Results of the Implementation of Best Practice in a Spanish National Health System (NHS)

The use of certain strategies for the implementation of a specific recommendation yields better results in clinical practice. The aim of this study was to assess the effectiveness of an evidence-based model using clinical audits (GRIP model), for the implementation of recommendations in pain and urinary incontinence management as well as fall prevention, in the Spanish National Health System during the period 2015-2018. A quasi-experimental study has been conducted. The subjects were patients treated in hospitals, primary care units and nursing home centers. There were measures related to pain, fall prevention and urinary incontinence. Measurements were taken at baseline and at months 3, 6, 9, and 12. The sample consisted of 22,114 patients. The frequency of pain assessment increased from 59.9% in the first cycle to a mean of 71.6% in the last cycle, assessments of risk of falling increased from 56.8% to 87.8% in the last cycle; and finally, the frequency of assessments of urinary incontinence increased from a 43.4% in the first cycles to a mean of 62.2% in the last cycles. The implementation of specific evidence-based recommendations on pain, fall prevention, and urinary incontinence using a model based on clinical audits improved the frequency of assessments and their documentation.

Publication and related bias in quantitative health services and delivery research: a multimethod study

Background

Bias in the publication and reporting of research findings (referred to as publication and related bias here) poses a major threat in evidence synthesis and evidence-based decision-making. Although this bias has been well documented in clinical research, little is known about its occurrence and magnitude in health services and delivery research.

Objectives

To obtain empirical evidence on publication and related bias in quantitative health services and delivery research; to examine current practice in detecting/mitigating this bias in health services and delivery research systematic reviews; and to explore stakeholders’ perception and experiences concerning such bias.

Methods

The project included five distinct but interrelated work packages. Work package 1 was a systematic review of empirical and methodological studies. Work package 2 involved a survey (meta-epidemiological study) of randomly selected systematic reviews of health services and delivery research topics (n = 200) to evaluate current practice in the assessment of publication and outcome reporting bias during evidence synthesis. Work package 3 included four case studies to explore the applicability of statistical methods for detecting such bias in health services and delivery research. In work package 4 we followed up four cohorts of health services and delivery research studies (total n = 300) to ascertain their publication status, and examined whether publication status was associated with statistical significance or perceived ‘positivity’ of study findings. Work package 5 involved key informant interviews with diverse health services and delivery research stakeholders (n = 24), and a focus group discussion with patient and service user representatives (n = 8).

Results

We identified only four studies that set out to investigate publication and related bias in health services and delivery research in work package 1. Three of these studies focused on health informatics research and one concerned health economics. All four studies reported evidence of the existence of this bias, but had methodological weaknesses. We also identified three health services and delivery research systematic reviews in which findings were compared between published and grey/unpublished literature. These reviews found that the quality and volume of evidence and effect estimates sometimes differed significantly between published and unpublished literature. Work package 2 showed low prevalence of considering/assessing publication (43%) and outcome reporting (17%) bias in health services and delivery research systematic reviews. The prevalence was lower among reviews of associations than among reviews of interventions. The case studies in work package 3 highlighted limitations in current methods for detecting these biases due to heterogeneity and potential confounders. Follow-up of health services and delivery research cohorts in work package 4 showed positive association between publication status and having statistically significant or positive findings. Diverse views concerning publication and related bias and insights into how features of health services and delivery research might influence its occurrence were uncovered through the interviews with health services and delivery research stakeholders and focus group discussion conducted in work package 5.

Conclusions

This study provided prima facie evidence on publication and related bias in quantitative health services and delivery research. This bias does appear to exist, but its prevalence and impact may vary depending on study characteristics, such as study design, and motivation for conducting the evaluation. Emphasis on methodological novelty and focus beyond summative assessments may mitigate/lessen the risk of such bias in health services and delivery research. Methodological and epistemological diversity in health services and delivery research and changing landscape in research publication need to be considered when interpreting the evidence. Collection of further empirical evidence and exploration of optimal health services and delivery research practice are required.

What works and why in the identification and referral of adults with comorbid obesity in primary care: A realist review

Primary care practitioners (PCPs) are well placed to identify individuals with obesity and weight-related comorbidities and to refer them to weight management services (WMS), but this does not often happen in practice. In this realist review, we searched six databases for intervention studies targeted at PCPs to improve the identification and referral of adults with comorbid obesity. Realist analysis was used to identify context-mechanism-outcome (CMO) configurations across 30 included papers (reporting on 27 studies). Most studies used multiple intervention strategies, categorised into: (a) training, (b) tools to improve identification, (c) tools to improve ease of referral, (d) audit/feedback, (e) working in networks/quality circles, and (f) other. The realist synthesis identified 12 mechanisms through which interventions work to improve identification and referral, including increasing knowledge about obesity and awareness of and confidence in WMS among practitioners, improved communication and trust between practitioners and WMS, and higher priority given to weight management among primary care teams. The theory of "candidacy" (a person's eligibility for medical attention and intervention) provided a robust explanatory framework but required refinement: (a) to take account of the different services (primary care and weight management) that patients must navigate to access support; and (b) to acknowledge the importance of wider contextual factors.

Obesity prevention and the role of hospital and community-based health services: a scoping review

BACKGROUND

Control of obesity is an important priority to reduce the burden of chronic disease. Clinical guidelines focus on the role of primary healthcare in obesity prevention. The purpose of this scoping review is to examine what the published literature indicates about the role of hospital and community based health services in adult obesity prevention in order to map the evidence and identify gaps in existing research.

METHODS

Databases were searched for articles published in English between 2006 and 2016 and screened against inclusion and exclusion criteria. Further papers were highlighted through a manual search of the reference lists. Included papers evaluated interventions aimed at preventing overweight and obesity in adults that were implemented within and/or by hospital and community health services; were an empirical description of obesity prevention within a health setting or reported health staff perceptions of obesity and obesity prevention.

RESULTS

The evidence supports screening for obesity of all healthcare patients, combined with referral to appropriate intervention services but indicates that health professionals do not typically adopt this practice. As well as practical issues such as time and resourcing, implementation is impacted by health professionals' views about the causes of obesity and doubts about the benefits of the health sector intervening once someone is already obese. As well as lacking confidence or knowledge about how to integrate prevention into clinical care, health professional judgements about who might benefit from prevention and negative views about effectiveness of prevention hinder the implementation of practice guidelines. This is compounded by an often prevailing view that preventing obesity is a matter of personal responsibility and choice.

CONCLUSIONS

This review highlights that whilst a population health approach is important to address the complexity of obesity, it is important that the remit of health services is extended beyond medical treatment to incorporate obesity prevention through screening and referral. Further research into the role of health services in obesity prevention should take a systems approach to examine how health service structures, policy and practice interrelationships, and service delivery boundaries, processes and perspectives impact on changing models of care.

Changing provider behaviour to increase nurse visits for obesity in family practice: the 5As Team randomized controlled trial

BACKGROUND

There is increasing recognition that health care professionals often fail to provide meaningful obesity care in routine clinical practice. There is scant information on how to support practice change. The objective of the 5AsT trial was to assess whether a co-created educational intervention would increase the quantity of obesity visits conducted by family practice nurses.

METHODS

We conducted a randomized controlled trial with convergent mixed-methods evaluation in a primary care network in Alberta, Canada. The intervention, based on the Theoretical Domains Framework and 5As of Obesity Management, included 12 2-hour interactive educational sessions from November 2013 to April 2014. Twenty-four teams of nurses, mental health workers and dietitians were randomly assigned to receive the intervention or regular training. The primary outcome measure was the rate ratio of nurse visits for adult obesity care to total clinical visits. Qualitative thematic analysis was previously used to identify barriers and facilitators to intervention uptake. In this study, mixed-methods analysis assessed the impact of these factors on individual nurses' outcomes.

RESULTS

There was no significant increase in visits over the 6-month intervention (rate ratio 1.30, 95% confidence interval [CI] 0.83-2.03) nor the 9-month post-intervention period (rate ratio 1.38, 95% CI 0.87-2.19). However, provider confidence, views of obesity management, role identity and team and patient relationships were found to affect individual nurses' uptake of the intervention.

INTERPRETATION

Although the intervention did not demonstrate a significant increase in nurse visits for obesity care, this study provides insights into health care practitioners' challenges in changing their approach to obesity management. To improve provider capacity to change effectively within their teams, interventions need to foster not only provider knowledge but also confidence. Trial registration: ClinicalTrials.gov, no. NCT01967797.

Constraints to implementing guidelines for the identification, assessment, and management of childhood obesity in the clinical care setting: Prevention and treatment framework

The "Pathway for the Identification, Assessment and Management of Overweight and Obese Children & Youth" was developed to support healthcare providers in identifying and treating childhood obesity in British Columbia (Canada).

Purpose

The study aimed to determine the feasibility and effectiveness of using the Pathway in clinical settings.

Methods

13 healthcare providers (7 family physicians, 2 pediatricians, 2 registered dietitians, and 2 nurse practitioners) assessed the Pathway and participated in semi-structured interviews in 2015. A direct constant comparative analysis guided the coding of the interviews in the NVivo 9 software.

Results

The interviews uncovered the complexity of factors that influenced practices of healthcare providers. Three broad issues were identified as required if the "Pathway" were to be used and fully implemented in practices. First, the "Pathway" needs to be modified in terms of how it is presented and explained and be supplemented with appropriate documentation and resources for its implementation, Second, the constraints that limit implementation need to be addressed and should include a focus on both individual (i.e., the healthcare providers themselves) and environmental (i.e., factors within and outside of providers' organizations) factors. Lastly, there is a need to establish processes and/or infrastructure for adapting the "Pathway" to the local context as resources and supports vary by organizations and regions.

Conclusion

Healthcare providers should be involved in screening and managing childhood obesity. Addressing the challenges found in this study will enable healthcare providers to take a more active role in addressing childhood obesity in their day to day practices.

Assessing Effectiveness and Cost-Benefit of the Trinity Hospital Twin City Fit For Life Program for Weight Loss and Diabetes Prevention in a Rural Midwestern Town

INTRODUCTION

Obesity is a top public health priority in the United States. This article reports on the Fit For Life (FFL) health education program designed to address the determinants of obesity in rural settings and help participants lose weight.

PURPOSE AND OBJECTIVES

We evaluated the implementation of the original FFL program, a replication program, and a diabetes-focused program.

INTERVENTION APPROACH

The original FFL program (2006 to 2012) was a 12-week session of classes meeting once weekly. Lecture topics included stress management, nutrition, healthy eating, reading food labels, fitness, disease prevention, and healthy aging. The replication program, conducted in 4 locations from 2012 to 2015, helped determine if the FFL program could be implemented on a larger scale, with outcomes similar to the original program. The longer, more-intensive FFL diabetes prevention program, conducted in 2016 and 2017, sought to reduce the number of rural adults at risk for diabetes.

EVALUATION METHODS

We evaluated FFL participation and outcome data from 2009 through first quarter 2017. We calculated rates of course participation and completion and measured changes in several health indicators. We constructed a linear regression model to examine the impact of health behaviors on weight loss and calculated program cost-effectiveness.

RESULTS

From 2009 to 2017, FFL was delivered to over 1,200 people; 82% of participants completed the program. Completing participants lost an average of 2.7 kg or 3% of their total weight. Overall, 68% of participants said they exercised more per week at the end of the program than at the beginning. Estimated cost per kilogram lost for replication sites was between $73 and $101 for original FFL, in line with other programs. The more resource-intensive diabetes prevention program cost per kilogram lost was $151 to $171.

IMPLICATIONS FOR PUBLIC HEALTH PRACTICE

Weight loss and lifestyle management are major ways to counteract obesity. Improving program options, especially in rural locales, should be a key policy priority. These programs should be considered for population-based expansion, perhaps by health departments or public-private health care consortiums.

Nutrition care practices of primary care providers for weight management in multidisciplinary primary care settings in Ontario, Canada - a qualitative study

Background

Despite the recommended guidelines on addressing diet for the management and prevention of obesity in primary care, the literature highlights that their implementation has been suboptimal. In this paper, we provide an in-depth understanding of current nutrition-related weight management practices of primary care providers (PCPs) working in relatively new multidisciplinary health care settings in Ontario.

Methods

Three types of multidisciplinary primary care settings were included (2 Family Health Teams, 3 Community Health Centres and 1 Nurse Practitioner-Led Clinic). Participants (n = 20) included in this study were nurse practitioners (n = 13) and family physicians (n = 7) supporting care for adult patients (18 years or older). In-depth interviews were transcribed, coded and the content was analyzed using an integrated approach.

Results

Our analysis showed that most PCPs used anthropometric measures such as weight for screening patients who would benefit from nutrition counselling with a dietitian. The topic of nutrition was generally brought up either during physical examinations, when patients were diagnosed with a chronic disease, or when blood markers were out of normal range. Participants also mentioned that physical examinations are no longer occurring annually, with most PCPs offering episodic care. All participants reported utilizing dietetic referrals, noting the enablers for providing the referral, which included access to an on-site dietitian. Nonetheless, dietetic referrals were mostly used when patients had an obesity-related co-morbidity. Participants mentioned that healthy eating advice was reinforced during follow-up visits with patients only when there was enough time to do so. Electronic Health Records (EHRs) were utilized to facilitate message reinforcement by PCPs, who perceived EHRs to be helpful for viewing what was discussed in the session with the dietitian.

Conclusions

PCPs mostly used objective measures to screen for patients who would benefit from nutrition counselling rather than diet assessment, which undermines the importance of dietary intake and overemphasizes weight. With physical examinations occurring less frequently, there will be additional missed opportunities for addressing nutrition-related concerns. The presence of a dietitian on site allowed for PCPs to refer patients to nutrition counselling. Having sufficient time during medical visits and EHRs seemed to facilitate message reinforcement by PCPs in follow-up visits with patients.

GestationaL Obesity Weight management: Implementation of National Guidelines (GLOWING): a pilot cluster randomised controlled trial of a guideline implementation intervention for the management of maternal obesity by midwives

BACKGROUND

Weight management in pregnancy guidelines exist, although dissemination alone is an ineffective means of implementation. Midwives identify the need for support to overcome complex barriers to practice. An evaluation of an intervention to support midwives' guideline implementation would require a large-scale cluster randomised controlled trial. A pilot study is necessary to explore the feasibility of delivery and evaluation prior to a definitive trial. The GestationaL Obesity Weight management: Implementation of National Guidelines (GLOWING) trial aims to test whether it is feasible and acceptable to deliver a behaviour change intervention to support midwives' implementation of weight management guidelines.

METHODS

GLOWING is a multi-centre parallel group pilot cluster randomised controlled trial comparing the delivery of a behaviour change intervention for midwives versus usual practice. Four NHS Trusts (clusters) will be randomised to intervention and control arms, stratified by size of maternity services. The intervention uses social cognitive theory and consists of face-to-face midwifery training plus information resources for routine practice. The main outcomes are whether the intervention and trial procedures are feasible and acceptable to participants and the feasibility of recruitment and data collection for a definitive trial. Target recruitment involves all eligible midwives in the intervention arm recruited to receive the intervention, 30 midwives and pregnant women per arm for baseline and outcome questionnaire data collection and 20 midwives and women to provide qualitative data. All quantitative and qualitative analyses will be descriptive with the purpose of informing the development of the definitive trial.

DISCUSSION

This pilot study has been developed to support community midwives' implementation of guidelines. Community midwives have been selected as they usually carry out the booking appointment which includes measuring and discussing maternal body mass index. A cluster design is the gold standard in implementation research as there would be a high risk of contamination if randomisation was at individual midwife level: community midwives usually work in locality-based teams, interact on a daily basis, and share care of pregnant women. The results of the pilot trial will be used to further develop and refine GLOWING prior to a definitive trial to evaluate effectiveness and cost-effectiveness.

Mapping the contribution of Allied Health Professions to the wider public health workforce: a rapid review of evidence-based interventions

Objectives

The objective was to identify a selection of the best examples of the public health contributions by Allied Health Professionals (AHPs) in order to encourage a wider awareness and participation from that workforce to public health practice.

Study design

A mapping exercise was used to identify evidence-based interventions that could lead to health improvements across a population.

Methods

A rapid review was undertaken to identify evidence, followed by a survey of Allied Health Profession (AHP) practitioners and an expert panel consensus method to select the examples of AHP public health interventions.

Results

Nine evidence-based interventions are identified and selected as examples of current AHP good practice. These examples represent a contribution to public health and include screening interventions, secondary prevention and risk management.

Conclusions

This study contributes to a strategy for AHPs in public health by appraising the effectiveness and impact of some exemplar AHP practices that contribute to health improvement. There is a need for AHPs to measure the impact of their interventions and to demonstrate evidence of outcomes at population level.

Interventions to change the behaviour of health professionals and the organisation of care to promote weight reduction in children and adults with overweight or obesity

BACKGROUND

The prevalence of overweight and obesity is increasing globally, an increase which has major implications for both population health and costs to health services. This is an update of a Cochrane Review.

OBJECTIVES

To assess the effects of strategies to change the behaviour of health professionals or the organisation of care compared to standard care, to promote weight reduction in children and adults with overweight or obesity.

SEARCH METHODS

We searched the following databases for primary studies up to September 2016: CENTRAL, MEDLINE, Embase, CINAHL, DARE and PsycINFO. We searched the reference lists of included studies and two trial registries.

SELECTION CRITERIA

We considered randomised trials that compared routine provision of care with interventions aimed either at changing the behaviour of healthcare professionals or the organisation of care to promote weight reduction in children and adults with overweight or obesity.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane when conducting this review. We report the results for the professional interventions and the organisational interventions in seven 'Summary of findings' tables.

MAIN RESULTS

We identified 12 studies for inclusion in this review, seven of which evaluated interventions targeting healthcare professional and five targeting the organisation of care. Eight studies recruited adults with overweight or obesity and four recruited children with obesity. Eight studies had an overall high risk of bias, and four had a low risk of bias. In total, 139 practices provided care to 89,754 people, with a median follow-up of 12 months. Professional interventions Educational interventions aimed at general practitioners (GPs), may slightly reduce the weight of participants (mean difference (MD) -1.24 kg, 95% confidence interval (CI) -2.84 to 0.37; 3 studies, N = 1017 adults; low-certainty evidence).Tailoring interventions to improve GPs' compliance with obesity guidelines probably leads to little or no difference in weight loss (MD 0.05 (kg), 95% CI -0.32 to 0.41; 1 study, N = 49,807 adults; moderate-certainty evidence).It is uncertain if providing doctors with reminders results in a greater weight reduction than standard care (men: MD -11.20 kg, 95% CI -20.66 kg to -1.74 kg, and women: MD -1.30 kg, 95% CI [-7.34, 4.74] kg; 1 study, N = 90 adults; very low-certainty evidence).Providing clinicians with a clinical decision support (CDS) tool to assist with obesity management at the point of care leads to little or no difference in the body mass index (BMI) z-score of children (MD -0.08, 95% CI -0.15 to -0.01 in 378 children; moderate-certainty evidence), CDS tools may lead to little or no difference in weight loss in adults: MD -0.095 kg (-0.21 lbs), P = 0.47; 1 study, N = 35,665; low-certainty evidence. Organisational interventions Adults with overweight or obesity may lose more weight if the care was provided by a dietitian (by -5.60 kg, 95% CI -4.83 kg to -6.37 kg) or by a doctor-dietitian team (by -6.70 kg, 95% CI -7.52 kg to -5.88 kg; 1 study, N = 270 adults; low-certainty evidence). Shared care leads to little or no difference in the BMI z-score of children with obesity (adjusted MD -0.05, 95% CI -0.14 to 0.03; 1 study, N = 105 children; low-certainty evidence).Organisational restructuring of the delivery of primary care (i.e. introducing the chronic care model) may result in a slightly lower increase in the BMI of children who received care at intervention clinics (BMI change: adjusted MD -0.21, 95% CI -0.50 to 0.07; 1 study, unadjusted MD -0.18, 95% CI -0.20 to -0.16; N=473 participants; moderate-certainty evidence).Mail and phone interventions probably lead to little or no difference in weight loss in adults (mean weight change (kg) using mail: -0.36, 95% CI -1.18 to 0.46; phone: -0.44, 95% CI -1.26 to 0.38; 1 study, N = 1801 adults; moderate-certainty evidence). Care delivered by a nurse at a primary care clinic may lead to little or no difference in the BMI z-score in children (MD -0.02, 95% CI -0.16 to 0.12; 1 study, N = 52 children; very low-certainty evidence).Two studies reported data on cost effectiveness: one study favoured mail and standard care over telephone consultations, and the other study achieved weight loss at a modest cost in both intervention groups (doctor and doctor-dietitian). One study of shared care reported similar adverse effects in both groups.

AUTHORS' CONCLUSIONS

We found little convincing evidence for a clinically-important effect on participants' weight or BMI of any of the evaluated interventions. While pooled results from three studies indicate that educational interventions targeting healthcare professionals may lead to a slight weight reduction in adults, the certainty of these results is low. Two trials evaluating CDS tools (unpooled results) for improved weight management suggest little or no effect on weight or BMI change in adults or children with overweight or obesity. Evidence for all the other interventions evaluated came mostly from single studies. The certainty of the included evidence varied from moderate to very low for the main outcomes (weight and BMI). All of the evaluated interventions would need further investigation to ascertain their strengths and limitations as effective strategies to change the behaviour of healthcare professionals or the organisation of care. As only two studies reported on cost, we know little about cost effectiveness across the evaluated interventions.

Developing dimensions for a multicomponent multidisciplinary approach to obesity management: a qualitative study

BACKGROUND

There have been consistent recommendations for multicomponent and multidisciplinary approaches for obesity management. However, there is no clear agreement on the components, disciplines or processes to be considered within such an approach. In this study, we explored multicomponent and multidisciplinary approaches through an examination of knowledge, skills, beliefs, and recommendations of stakeholders involved in obesity management. These stakeholders included researchers, practitioners, educators, and patients.

METHODS

We used qualitative action research methods, including convergent interviewing and observation, to assist the process of inquiry.

RESULTS

The consensus was that a multicomponent and multidisciplinary approach should be based on four central meta-components (patient, practitioner, process, and environmental factors), and specific components of these factors were identified. Psychologists, dieticians, exercise physiologists and general practitioners were nominated as key practitioners to be included.

CONCLUSIONS

A complex condition like obesity requires that multiple components be addressed, and that both patients and multiple disciplines are involved in developing solutions. Implementing cycles of continuous improvement to deal with complexity, instead of trying to control for it, offers an effective way to deal with complex, changing multisystem problems like obesity.

Impact of the 5As Team study on clinical practice in primary care obesity management: a qualitative study

BACKGROUND

The 5As [Ask, Assess, Advise, Agree, Assist] of Obesity Management Team study was a randomized controlled trial of an intervention that was implemented and evaluated to help primary care providers improve clinical practice for obesity management. This paper presents health care provider perspectives of the impacts of the intervention on individual provider and team practices.

METHODS

This study reports a thematic network analysis of qualitative data collected during the 5As Team study, which involved 24 chronic disease teams affiliated with family practices in a Primary Care Network in Alberta. Qualitative data from 28 primary care providers (registered nurses/nurse practitioners [n = 14], dietitians [n = 7] and mental health workers [n = 7]) in the intervention arm were collected through semistructured interviews, field notes, practice facilitator diaries and 2 evaluation workshop questionnaires.

RESULTS

Providers internalized 5As Team intervention concepts, deepening self-evaluation and changing clinical reasoning around obesity. Providers perceived that this internalization changed the provider-patient relationship positively. The intervention changed relations between providers, increasing interdisciplinary understanding, collaboration and discovery of areas for improvement. This personal and interpersonal evolution effected change to the entire Primary Care Network.

INTERPRETATION

The 5As Team intervention had multiple impacts on providers and teams to improve obesity management in primary care. Improved provider confidence and capability is a precondition of developing effective patient interventions. Trial registration: ClinicalTrials.gov, no.: NCT01967797.

Eliciting Provider and Patient Perspectives on New Obesity Management Services in a Team-Based Primary Care Organization

PURPOSE

Both providers and patients may have important insights to inform the development of obesity prevention and management services in Canadian primary care settings. In this formative study, insights for new obesity management services were sought from both providers and patients in 1 progressive citywide organization (150 physicians, team services, separate offices).

METHODS

Seven focus groups with interprofessional health providers (n = 56) and 4 focus groups with patients (n = 34) were conducted. Two clinical vignettes (adult, child) were used to focus discussion. Four analysts coded for descriptive content and interpretative themes on possible tools and care processes using NVivo.

RESULTS

Participants identified numerous strategies for care processes, most of which could be categorized into 1 or more of 11 themes: 6 directed at clinical care of patients (raising awareness, screening, clinical care, skill building, ongoing support, and social/peer support) and 5 directed at the organization (coordination/collaboration, creating awareness among health professionals, adding new expertise to the team, marketing, and lobbying/advocacy).

CONCLUSIONS

The approach was successful in generating an extensive list of diverse activities to be considered for implementation studies. Both patients and providers identified that multiple strategies and systems approaches will be needed to address obesity management in primary care.

AIMD - a validated, simplified framework of interventions to promote and integrate evidence into health practices, systems, and policies

Background

Proliferation of terms describing the science of effectively promoting and supporting the use of research evidence in healthcare policy and practice has hampered understanding and development of the field. To address this, an international Terminology Working Group developed and published a simplified framework of interventions to promote and integrate evidence into health practices, systems, and policies. This paper presents results of validation work and a second international workgroup meeting, culminating in the updated AIMD framework [Aims, Ingredients, Mechanism, Delivery].

Methods

Framework validity was evaluated against terminology schemas (n = 51); primary studies (n = 37); and reporting guidelines (n = 10). Framework components were independently categorized as fully represented, partly represented, or absent by two researchers. Opportunities to refine the framework were systematically recorded. A meeting of the expanded international Terminology Working Group updated the framework by reviewing and deliberating upon validation findings and refinement proposals.

Results

There was variation in representativeness of the components across the three types of literature, in particular for the component ‘causal mechanisms’. Analysis of primary studies revealed that representativeness of this concept lowered from 92 to 68% if only explicit, rather than explicit and non-explicit references to causal mechanisms were included.

All components were very well represented in reporting guidelines, however the level of description of these was lower than in other types of literature. Twelve opportunities were identified to improve the framework, 9 of which were operationalized at the meeting. The updated AIMD framework comprises four components: (1) Aims: what do you want your intervention to achieve and for whom? (2) Ingredients: what comprises the intervention? (3) Mechanisms: how do you propose the intervention will work? and (4) Delivery: how will you deliver the intervention?

Conclusions

The draft simplified framework was validated with reference to a wide range of relevant literature and improvements have enhanced useability. The AIMD framework could aid in the promotion of evidence into practice, remove barriers to understanding how interventions work, enhance communication of interventions and support knowledge synthesis. Future work needs to focus on developing and testing resources and educational initiatives to optimize use of the AIMD framework in collaboration with relevant end-user groups.

A personalized, multi-platform nutrition, exercise, and lifestyle coaching program: A pilot in women

The aim of this pilot study was to examine if a personalized web-based multi-platform nutrition, exercise, and lifestyle coaching program, supported weight loss and the reduction of chronic disease risk factors in overweight or obese women. Twenty-eight women completed the program, which represented 50% of those who provided baseline data. The program consisted of a one-year curriculum with daily exercise, nutritional habits, and health behaviour lessons along with access to a one-on-one coach. The workouts, habits, and lessons were available via computer, tablet, and mobile device which, along with coaching, facilitated self-monitoring and accountability. At baseline and 12-months, weight, waist circumference, fat mass, muscle mass, blood pressure, total cholesterol, low density lipoproteins, high density lipoproteins, triglycerides, C reactive protein, and fasting glucose were collected. Over the 12 months, women who completed the program, (average age 49.64 (SD 10.99) years), lost 16.52 (SD 13.63) lbs (P < 0.001), and reduced waist circumference by 3.56 (SD 2.31) in (P < 0.0001). Diastolic blood pressure decreased by 3.77 (SD 7.25) mm Hg (P = 0.02) and high density lipoproteins increased by 0.16 (SD 0.28) mmol/L (P = 0.01). No other risk factors changed significantly. Compliance was a significant predictor of weight loss (P < 0.01). In conclusion, women who completed the web-based program experienced significant weight loss (8.62% of initial body weight) coming predominantly from body fat. Chronic disease risk factors also improved.

Interventions for sustained healthcare professional behaviour change: a protocol for an overview of reviews

BACKGROUND

Failure to successfully implement and sustain change over the long term continues to be a major problem in health and social care. Translating evidence into routine clinical practice is notoriously complex, and it is recognised that to implement new evidence-based interventions and sustain them over time, professional behaviour needs to change accordingly. A number of theories and frameworks have been developed to support behaviour change among health and social care professionals, and models of sustainability are emerging, but few have translated into valid and reliable interventions. The long-term success of healthcare professional behavioural change interventions is variable, and the characteristics of successful interventions unclear. Previous reviews have synthesised the evidence for behaviour change, but none have focused on sustainability. In addition, multiple overlapping reviews have reported inconsistent results, which do not aid translation of evidence into practice. Overviews of reviews can provide accessible succinct summaries of evidence and address barriers to evidence-based practice. We aim to compile an overview of reviews, identifying, appraising and synthesising evidence relating to sustained social and healthcare professional behaviour change.

METHODS

We will conduct a systematic review of Cochrane reviews (an Overview). We plan to systematically search the Cochrane Database of Systematic Reviews. We will include all systematic reviews of randomised controlled trials comparing a healthcare professional targeted behaviour change intervention to a standard care or no intervention control group. Two reviewers will independently assess the eligibility of the reviews and the methodological quality of included reviews using the ROBIS tool. The quality of evidence within each comparison in each review will be judged based on the GRADE criteria. Disagreements will be resolved through discussion. Effects of interventions will be systematically tabulated and the quality of evidence used to determine implications for clinical practice and make recommendations for future research.

DISCUSSION

This overview will bring together the best available evidence relating to the sustainability of health professional behaviour change, thus supporting policy makers with decision-making in this field.

Predictors of weight loss in young adults who are over-weight or obese and have psychosocial problems: a post hoc analysis

Background

The aim of this study is in a general practice trial setting to identify predictive factors for weight loss after 1 year among young adults who are over-weight or obese and who have several psychosocial problems.

Methods

Twenty-eight general practitioners recruited 495 patients aged 20–45 years with psychosocial problems for a randomized general preventive study to increase self-efficacy to achieve a self-prioritised goal for a better life by discussions of resources and barriers for reaching the goal. The present study is a post hoc analysis of possible predictors of weight loss among all 218 patients who have over-weight or obesity. A 23-pages questionnaire was completed before and 1 year after randomization. 111 patients had a one-hour preventive health consultation with their general practitioners focused on life coaching and a follow-up consultation within 3 months, and 107 patients had no preventive consultation.

Results

Twenty-two patients stated during the preventive consultation that weight loss was a prioritised goal. They had a mean weight loss of 4.7 kgs compared with 1.6 kgs in the group without this goal and 1.6 kgs in the group without preventive consultation. In a logistic regression model, predictors of weight loss or no weight loss were a) pre-interventional consideration of weight loss within 30 days, b) having weight loss as a prioritised goal for improved quality of life, c) being female, d) being in the oldest half of participants, and e) having many psychosocial problems. In a linear regression model, the predictors together explained about 11 % of the weight loss. Important predictors were: obesity (explained 4 %), pre-interventional consideration of weight loss within 30 days (3 %), and having a preventive health consultation with weight loss as a prioritised goal (2 %).

Conclusions

Pre-interventional consideration of weight loss within 30 days and having weight loss as a prioritised goal during the health consultation were two important predictors for weight loss. By structured interventions focussing on the patients’ priorities, self-chosen goals, their resources and barriers for reaching the goals, changes may be obtained; especially in participants with many problems who often do not accept participation in procedures on risks.

Challenges in interdisciplinary weight management in primary care: lessons learned from the 5As Team study

Increasingly, research is directed at advancing methods to address obesity management in primary care. In this paper we describe the role of interdisciplinary collaboration, or lack thereof, in patient weight management within 12 teams in a large primary care network in Alberta, Canada. Qualitative data for the present analysis were derived from the 5As Team (5AsT) trial, a mixed-method randomized control trial of a 6-month participatory, team-based educational intervention aimed at improving the quality and quantity of obesity management encounters in primary care practice. Participants (n = 29) included in this analysis are healthcare providers supporting chronic disease management in 12 family practice clinics randomized to the intervention arm of the 5AsT trial including mental healthcare workers (n = 7), registered dietitians (n = 7), registered nurses or nurse practitioners (n = 15). Participants were part of a 6-month intervention consisting of 12 biweekly learning sessions aimed at increasing provider knowledge and confidence in addressing patient weight management. Qualitative methods included interviews, structured field notes and logs. Four common themes of importance in the ability of healthcare providers to address weight with patients within an interdisciplinary care team emerged, (i) Availability; (ii) Referrals; (iii) Role perception and (iv) Messaging. However, we find that what was key to our participants was not that these issues be uniformly agreed upon by all team members, but rather that communication and clinic relationships support their continued negotiation. Our study shows that firm clinic relationships and deliberate communication strategies are the foundation of interdisciplinary care in weight management. Furthermore, there is a clear need for shared messaging concerning obesity and its treatment between members of interdisciplinary teams.

The role of the family doctor in the management of adults who are obese: a scoping review protocol

Background

The role of family doctors in the management of obesity in primary care will become increasingly important as more of the adult population become overweight or obese. Having a solid understanding of the family doctor’s role as a sole practitioner is important for supporting practitioners in providing patient care and for informing future research.

Objective

The purpose of this paper is to describe a protocol for a scoping review that aims to examine and map the current research base for the role of the family doctor in managing adults who are overweight or obese.

Methods

This scoping review is based on the methodology as described by the Joanna Briggs Institute which involves final consultation with stakeholders. Two reviewers (ES, NE) will be responsible for the iterative development of a search strategy based on the basic initial search terms obesity, doctor and primary care. Black and grey literature will be searched to elucidate any manuscripts involving the family doctor in the management of adults who are overweight or obese. A customised data extraction tool will be used to collect relevant items from each manuscript.

Results

Data extraction will expose the role family doctors are playing in obesity management in all stages of research including recruitment, intervention or as a control group. By looking at a broad scope of manuscripts we will discover the family doctor’s role as portrayed in research, in international guidelines and by peak bodies. We will also determine if there are any gaps in the research base.

Conclusion

This protocol describes a scoping review that will illustrate the supporting international research for the role family doctors are playing in the management of adults who are overweight or obese. Scoping of the international literature will then be translated for Australian primary care.

Achieving change in primary care--effectiveness of strategies for improving implementation of complex interventions: systematic review of reviews

OBJECTIVE

To identify, summarise and synthesise available literature on the effectiveness of implementation strategies for optimising implementation of complex interventions in primary care.

DESIGN

Systematic review of reviews.

DATA SOURCES

MEDLINE, EMBASE, CINAHL, Cochrane Library and PsychINFO were searched, from first publication until December 2013; the bibliographies of relevant articles were screened for additional reports.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Eligible reviews had to (1) examine effectiveness of single or multifaceted implementation strategies, (2) measure health professional practice or process outcomes and (3) include studies from predominantly primary care in developed countries. Two reviewers independently screened titles/abstracts and full-text articles of potentially eligible reviews for inclusion.

DATA SYNTHESIS

Extracted data were synthesised using a narrative approach.

RESULTS

91 reviews were included. The most commonly evaluated strategies were those targeted at the level of individual professionals, rather than those targeting organisations or context. These strategies (eg, audit and feedback, educational meetings, educational outreach, reminders) on their own demonstrated a small to modest improvement (2-9%) in professional practice or behaviour with considerable variability in the observed effects. The effects of multifaceted strategies targeted at professionals were mixed and not necessarily more effective than single strategies alone. There was relatively little review evidence on implementation strategies at the levels of organisation and wider context. Evidence on cost-effectiveness was limited and data on costs of different strategies were scarce and/or of low quality.

CONCLUSIONS

There is a substantial literature on implementation strategies aimed at changing professional practices or behaviour. It remains unclear which implementation strategies are more likely to be effective than others and under what conditions. Future research should focus on identifying and assessing the effectiveness of strategies targeted at the wider context and organisational levels and examining the costs and cost-effectiveness of implementation strategies.

The 5As team intervention: bridging the knowledge gap in obesity management among primary care practitioners

Background

Despite opportunities for didactic education on obesity management, we still observe low rates of weight management visits in our primary care setting. This paper describes the co-creation by front-line interdisciplinary health care providers and researchers of the 5As Team intervention to improve obesity prevention and management in primary care.

Methods

We describe the theoretical foundations, design, and core elements of the 5AsT intervention, and the process of eliciting practitioners’ self-identified knowledge gaps to inform the curricula for the 5AsT intervention. Themes and topics were identified through facilitated group discussion and a curriculum relevant to this group of practitioners was developed and delivered in a series of 12 workshops.

Result

The research question and approach were co-created with the clinical leadership of the PCN; the PCN committed internal resources and a practice facilitator to the effort. Practice facilitation and learning collaboratives were used in the intervention For the content, front-line providers identified 43 topics, related to 13 themes around obesity assessment and management for which they felt the need for further education and training. These needs included: cultural identity and body image, emotional and mental health, motivation, setting goals, managing expectations, weight-bias, caregiver fatigue, clinic dynamics and team-based care, greater understanding of physiology and the use of a systematic framework for obesity assessment (the “4Ms” of obesity). The content of the 12 intervention sessions were designed based on these themes. There was a strong innovation values fit with the 5AsT intervention, and providers were more comfortable with obesity management following the intervention. The 5AsT intervention, including videos, resources and tools, has been compiled for use by clinical teams and is available online at http://www.obesitynetwork.ca/5As_Team.

Conclusions

Primary care interdisciplinary practitioners perceive important knowledge gaps across a wide range of topics relevant to obesity assessment and management. This description of the intervention provides important information for trial replication. The 5AsT intervention may be a useful aid for primary care teams interested to improve their knowledge of obesity prevention and management.

Missing an opportunity: the embedded nature of weight management in primary care

The 5As Team study was designed to create, implement and evaluate a flexible intervention to improve the quality and quantity of weight management visits in primary care. The objective of this portion of the study was to explore how primary care providers incorporate weight management in their practice. 5AsT is a randomized controlled trial (RCT) on the implementation of a 6-month 5 As Team (5AsT) intervention designed to operationalize the 5As of obesity management in primary care. Data for the qualitative portion of the study presented here included semi-structured interviews with 29 multidisciplinary team providers and field notes of intervention sessions. Thematic analysis was undertaken. A key pattern that emerged from the data was that healthcare providers usually do not address obesity as a primary focus for a visit. Rather, obesity is embedded in a wide range of primary care encounters for other conditions. Implications were it can take extra time to discuss weight, it can be inappropriate to bring up weight as a topic, and treating risk factors and root causes of obesity have indirect benefits to patient weight management. Our findings have implications for obesity treatment approaches and tools that assume a discreet weight management visit. The embedded nature of obesity management in primary care can be harnessed to leverage multiple opportunities for asking and assessing root causes of obesity, and working longitudinally towards individual health goals.

A Clinical Protocol for the Assessment of Obesity: Addressing an Epidemic

The purpose of this article is to discuss the importance of addressing obesity, a national epidemic. Furthermore, the paper focuses on the utilization of a clinical practice protocol for identifying patients who are obese or at risk for obesity in the primary care setting. The practice protocol includes guidelines for assessment, documentation, and a consistent educational intervention for the identified priority population. The rapidly increasing incidence of obesity in our primary care practices supports the need for evidence-based approaches to ensure consistent assessment and documentation, thereby increasing the potential for weight management and obesity reduction.

Making the connection-factors influencing implementation of evidence supported and non-evaluated lifestyle interventions in healthcare: a multiple case study

Many implementation barriers relate to lifestyle interventions (LIs) being developed by scientists. Exploring whether implementation of non-evaluated LIs is less complicated, might offer insight how to improve the use of effective interventions. This study aimed to identify influencing factors for implementation and compare factors between evidence supported and non-evaluated LIs. Evidence-supported (n = 7) and non-evaluated LIs (n = 7) in hospitals, general practices and community care organizations were included as cases. Semi-structured interviews (n = 46) were conducted. Additionally, documents (n = 207) were collected describing intervention, implementation process, and policy. We used a stepwise approach to inductively identify factors, organize them by diffusion phase, and an existing framework. A total of 37 factors were identified. 'Dissemination' factors were mainly observed in evidence-supported LIs. 'Compatibility to existing structures' ('adoption'), 'funding' and 'connection to existing care processes' ('implementation') was factors identified in all cases. 'Quality control' and 'ongoing innovation' ('maintenance') were reported in evidence-supported interventions. In all domains of the framework factors were observed. Factors identified in this study are in line with the literature. The findings do not support the assumption that implementation of non-evaluated LIs is perceived as less complex.

Gap Between Evidence and Patient Access: Policy Implications for Bariatric and Metabolic Surgery in the Treatment of Obesity and its Complications

Despite consistently supportive evidence of clinical effectiveness and economic advantages compared with currently available non-surgical obesity treatments, patient access to bariatric and metabolic surgery (BMS) is impeded. To address this gap and better understand the relationship between value and access, the objectives of this study were twofold: (i) identify the multidimensional barriers to adoption of BMS created by clinical guidelines, public policies, and health technology assessments; and, most importantly, (ii) develop recommendations for stakeholders to improve patient access to BMS. Updated public policies focused on treatment and clinical guidelines that reflect the demonstrated advantages of BMS, patient education on safety and effectiveness, updated reimbursement policies, and additional data on long-term BMS effectiveness are needed to improve patient access.

Social network analysis for program implementation

This paper introduces the use of social network analysis theory and tools for implementation research. The social network perspective is useful for understanding, monitoring, influencing, or evaluating the implementation process when programs, policies, practices, or principles are designed and scaled up or adapted to different settings. We briefly describe common barriers to implementation success and relate them to the social networks of implementation stakeholders. We introduce a few simple measures commonly used in social network analysis and discuss how these measures can be used in program implementation. Using the four stage model of program implementation (exploration, adoption, implementation, and sustainment) proposed by Aarons and colleagues [1] and our experience in developing multi-sector partnerships involving community leaders, organizations, practitioners, and researchers, we show how network measures can be used at each stage to monitor, intervene, and improve the implementation process. Examples are provided to illustrate these concepts. We conclude with expected benefits and challenges associated with this approach.

The organisation and delivery of health improvement in general practice and primary care: a scoping study

Background

This project examines the organisation and delivery of health improvement activities by and within general practice and the primary health-care team. The project was designed to examine who delivers these interventions, where they are located, what approaches are developed in practices, how individual practices and the primary health-care team organise such public health activities, and how these contribute to health improvement. Our focus was on health promotion and ill-health prevention activities.

Aims

The aim of this scoping exercise was to identify the current extent of knowledge about the health improvement activities in general practice and the wider primary health-care team. The key objectives were to provide an overview of the range and type of health improvement activities, identify gaps in knowledge and areas for further empirical research. Our specific research objectives were to map the range and type of health improvement activity undertaken by general practice staff and the primary health-care team based within general practice; to scope the literature on health improvement in general practice or undertaken by health-care staff based in general practice and identify gaps in the evidence base; to synthesise the literature and identify effective approaches to the delivery and organisation of health improvement interventions in a general practice setting; and to identify the priority areas for research as defined by those working in general practice.

Methods

We undertook a comprehensive search of the literature. We followed a staged selection process involving reviews of titles and abstracts. This resulted in the identification of 1140 papers for data extraction, with 658 of these papers selected for inclusion in the review, of which 347 were included in the evidence synthesis. We also undertook 45 individual and two group interviews with primary health-care staff.

Findings

Many of the research studies reviewed had some details about the type, process or location, or who provided the intervention. Generally, however, little attention is paid in the literature to examining the impact of the organisational context on the way services are delivered or how this affects the effectiveness of health improvement interventions in general practice. We found that the focus of attention is mainly on individual prevention approaches, with practices engaging in both primary and secondary prevention. The range of activities suggests that general practitioners do not take a population approach but focus on individual patients. However, it is clear that many general practitioners see health promotion as an integral part of practice, whether as individual approaches to primary or secondary health improvement or as a practice-based approach to improving the health of their patients. Our key conclusion is that there is currently insufficient good evidence to support many of the health improvement interventions undertaken in general practice and primary care more widely.

Future Research

Future research on health improvement in general practice and by the primary health-care team needs to move beyond clinical research to include delivery systems and be conducted in a primary care setting. More research needs to examine areas where there are chronic disease burdens – cancer, dementia and other disabilities of old age. Reviews should be commissioned that examine the whole prevention pathway for health problems that are managed within primary care drawing together research from general practice, pharmacy, community engagement, etc.

Interventions targeted at primary care practitioners to improve the identification and referral of patients with co-morbid obesity: a realist review protocol

BACKGROUND

Obesity is one of the most significant public health challenges in the developed world. Recent policy has suggested that more can be done in primary care to support adults with obesity. In particular, general practitioners (GPs) and practice nurses (PNs) could improve the identification and referral of adults with obesity to appropriate weight management services. Previous interventions targeted at primary care practitioners in this area have had mixed results, suggesting a more complex interplay between patients, practitioners, and systems. The objectives of this review are (i) to identify the underlying 'programme theory' of interventions targeted at primary care practitioners to improve the identification and referral of adults with obesity and (ii) to explore how and why GPs and PNs identify and refer individuals with obesity, particularly in the context of weight-related co-morbidity. This protocol will explain the rationale for using a realist review approach and outline the key steps in this process.

METHODS

Realist review is a theory-led approach to knowledge synthesis that provides an explanatory analysis aimed at discerning what works, for whom, in what circumstances, how, and why. In this review, scoping interviews with key stakeholders involved in the planning and delivery of adult weight management services in Scotland helped to inform the identification of formal theories - from psychology, sociology, and implementation science - that will be tested as the review progresses. A comprehensive search strategy is described, including scope for iterative searching. Data analysis is outlined in three stages (describing context-mechanism-outcome configurations, exploring patterns in these configurations, and developing and testing middle-range theories, informed by the formal theories previously identified), culminating in the production of explanatory programme theory that considers individual, interpersonal, and institutional/systems-level components.

DISCUSSION

This is the first realist review that we are aware of looking at interventions targeted at primary care practitioners to improve the weight management of adults with obesity. Engagement with stakeholders at an early stage is a unique feature of realist review. This shapes the scope of the review, identification of candidate theories and dissemination strategies. The findings of this review will inform policy and future interventions.

Translation of obesity practice guidelines: interprofessional perspectives regarding the impact of public health nurse system-level intervention

OBJECTIVE

The purpose of the study was to investigate the perceptions of administrators and clinicians regarding a public health facilitated collaborative supporting the translation into practice of the Institute for Clinical Systems Improvement (ICSI) Adult Obesity Guideline.

DESIGN AND SAMPLE

This qualitative study was conducted with 10 health care organizations participating in a voluntary, interprofessional obesity management collaborative. A purposive sample of 39 participants included two to three clinicians and an administrator from each organization. Interview analysis focused on how the intervention affected participants and their practices.

RESULTS

Four themes described participant experiences of obesity guideline translation: (1) a shift from powerlessness to positive motivation, (2) heightened awareness coupled with improved capacity to respond, (3) personal ownership and use of creativity, and (4) a sense of the importance of increased interprofessional collaboration.

CONCLUSIONS

The investigation of interprofessional perspectives illuminates the feelings and perceptions of clinician and administrator participants regarding obesity practice guideline translation. These themes suggest that positive motivation, improved capacity, personal creative ownership, and interprofessional collaboration may be conducive to successful evidence-based obesity guideline implementation. Further research is needed to evaluate these findings relative to translating the ICSI obesity guideline and other guidelines into practice in diverse clinical settings.

Reducing Care Utilisation through Self-management Interventions (RECURSIVE): a systematic review and meta-analysis

Background

A critical part of future service delivery will involve improving the degree to which people become engaged in ‘self-management’. Providing better support for self-management has the potential to make a significant contribution to NHS efficiency, as well as providing benefits in patient health and quality of care.

Objective

To determine which models of self-management support are associated with significant reductions in health services utilisation (including hospital use) without compromising outcomes, among patients with long-term conditions.

Data sources

Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health, EconLit (the American Economic Association’s electronic bibliography), EMBASE, Health Economics Evaluations Database, MEDLINE (the US National Library of Medicine’s database), MEDLINE In-Process & Other Non-Indexed Citations, NHS Economic Evaluation Database (NHS EED) and PsycINFO (the behavioural science and mental health database), as well as the reference lists of published reviews of self-management support.

Methods

We included patients with long-term conditions in all health-care settings and self-management support interventions with varying levels of additional professional support and input from multidisciplinary teams. Main outcome measures were quantitative measures of service utilisation (including hospital use) and quality of life (QoL). We presented the results for each condition group using a permutation plot, plotting the effect of interventions on utilisation and outcomes simultaneously and placing them in quadrants of the cost-effectiveness plane depending on the pattern of outcomes. We also conducted conventional meta-analyses of outcomes.

Results

We found 184 studies that met the inclusion criteria and provided data for analysis. The most common categories of long-term conditions included in the studies were cardiovascular (29%), respiratory (24%) and mental health (16%). Of the interventions, 5% were categorised as ‘pure self-management’ (without additional professional support), 20% as ‘supported self-management’ (< 2 hours’ support), 47% as ‘intensive self-management’ (> 2 hours’ support) and 28% as ‘case management’ (> 2 hours’ support including input from a multidisciplinary team). We analysed data across categories of long-term conditions and also analysed comparing self-management support (pure, supported, intense) with case management. Only a minority of self-management support studies reported reductions in health-care utilisation in association with decrements in health. Self-management support was associated with small but significant improvements in QoL. Evidence for significant reductions in utilisation following self-management support interventions were strongest for interventions in respiratory and cardiovascular disorders. Caution should be exercised in the interpretation of the results, as we found evidence that studies at higher risk of bias were more likely to report benefits on some outcomes. Data on hospital use outcomes were also consistent with the possibility of small-study bias.

Limitations

Self-management support is a complex area in which to undertake literature searches. Our analyses were limited by poor reporting of outcomes in the included studies, especially concerning health-care utilisation and costs.

Conclusions

Very few self-management support interventions achieve reductions in utilisation while compromising patient outcomes. Evidence for significant reductions in utilisation were strongest for respiratory disorders and cardiac disorders. Research priorities relate to better reporting of the content of self-management support, exploration of the impact of multimorbidity and assessment of factors influencing the wider implementation of self-management support.

Interventions to change maternity healthcare professionals' behaviours to promote weight-related support for obese pregnant women: a systematic review

Background

There has been a rapid increase in the publication of guidelines for managing obesity and weight gain during pregnancy over the past five years. Healthcare professionals have identified multiple barriers to this area of practice, including the need to improve their communication skills, beliefs that pregnant women will have negative reactions to weight-related discussions, and a lack of weight management knowledge. This systematic review aimed to identify: the effectiveness of interventions in changing healthcare professionals’ practice relating to maternal obesity or weight management during pregnancy; and which behaviour change techniques and modes of intervention delivery have been used in interventions to date.

Findings

The search strategy included searching electronic databases, trial registers, and citation searching. Inclusion criteria were intervention studies targeted towards changing healthcare professionals’ practice in relation to maternal obesity or weight management. The searches identified 3,608 studies. However, no eligible completed studies were identified. One registered Canadian randomised controlled trial was identified. The trial includes a training intervention for family physicians with the aim of supporting adherence to gestational weight gain guidelines. The trial had not yet commenced therefore no effectiveness data were available.

Conclusions

The current focus of maternal obesity and weight management research is targeted towards changing pregnant women’s behaviours. These interventions do not address the multiple healthcare professionals’ barriers to maternal obesity and weight management practice. Further research is required to identify the most effective approaches to support healthcare professionals to implement maternal obesity and weight management guidelines into practice.

Exploring obesogenic environments: the design and development of the migrant obesogenic perception of the environment questionnaire (MOPE-Q) using a sample of Iranian migrants in Australia

Background

Although there are a number of studies examining the effect of migration on obesity, these studies tend to focus on the role of acculturation in this relationship. However, there are indications that the change in environment may also be an important factor. Indeed, there is a considerable lack of psychometric tools designed to assess the association between environment and migrant health behaviour. The current study aimed to assess the literature on the link between environment and health for migrants, and on the basis of this information, design and develop the Migrant Obesogenic Perception of the Environment questionnaire (MOPE-Q). The MOPE-Q is the first comprehensive measure of the impact of environmental factors on migrant health behaviour related to physical activity, food habits and body image concern, as well as weight change.

Methods

Using a systematic approach, an initial pool of items for the questionnaire was developed and refined on the basis of rigorous content and face validity assessments and factor analysis. Further, reliability tests and test re-test studies were undertaken. Differences between Iranian and Australian environmental factors as they relate to obesogenic behaviour were explored using the developed measure.

Results

A total of 36 items were developed for the MOPE-Q. Principal factor analysis identified three similar factor structures of environmental factors related to obesity (categorized in terms of facilitators, barriers and pressures) for each country. The final questionnaire consisted of four distinct subscales pertaining specifically to the Australian environment and five subscales pertaining to the Iranian environment, accounting for 59% and 63%, respectively, of the total variance in obesity rates. Data suggests that the MOPE-Q is a reliable and valid self-report measure for assessing the relationship between environmental factors linked to obesity and obesogenic behaviour for this particular migrant group.

Conclusion

The variations in environmental factors linked to obesity behaviour between home (Iran) and host (Australia) countries have been incorporated into the MOPE-Q instrument which has shown good psychometric properties. The MOPE-Q can be adapted and applied to other environments and populations to help explain changes in diet, physical activity patterns and body weight in migrant groups as they acculturate.

Evaluation of a tailored intervention to improve management of overweight and obesity in primary care: study protocol of a cluster randomised controlled trial

BACKGROUND

In the UK around 22% of men and 24% of women are obese, and there are varying but worrying levels in other European countries. Obesity is a chronic condition that carries an important health risk. National guidelines, for use in England, on the management of people who are overweight or obese have been published by the National Institute for Health and Clinical Excellence (NICE, 2006). NICE recommendations for primary care teams are: determine the degree of overweight and obesity; assess lifestyle, comorbidities and willingness to change; offer multicomponent management of overweight and obesity; referral to external services when appropriate. This study investigates a tailored intervention to improve the implementation of these recommendations by primary care teams.

METHODS/DESIGN

The study is a cluster randomised controlled trial. Primary care teams will be recruited from the East Midlands of England, and randomised into two study arms: 1) the study group, in which primary care teams are offered a set of tailored interventions to help implement the NICE guidelines for overweight and obesity; or 2) the control group in which primary care teams continue to practice usual care. The primary outcome is the proportion of overweight or obese patients for whom the primary care team adheres to the NICE guidelines. Secondary outcomes include the proportion of patients with a record of lifestyle assessment, referral to external weight loss services, the proportion of obese patients who lose weight during the intervention period, and the mean weight change over the same period.

DISCUSSION

Although often recommended, the methods of tailoring implementation interventions to account for the determinants of practice are not well developed. This study is part of a programme of studies seeking to develop the methods of tailored implementation.

Dietary advice for reducing cardiovascular risk

BACKGROUND

Changes in population diet are likely to reduce cardiovascular disease and cancer, but the effect of dietary advice is uncertain. This review is an update of a previous review published in 2007.

OBJECTIVES

To assess the effects of providing dietary advice to achieve sustained dietary changes or improved cardiovascular risk profile among healthy adults.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials, the Database of Abstracts of Reviews of Effects (DARE) and the HTA database on The Cochrane Library (Issue 4, 2010). We searched MEDLINE (Ovid) (1950 to week 2 October 2010) and EMBASE (Ovid) (1980 to Week 42 2010). Additional searches were done on CAB Health (1972 to December 1999), CVRCT registry (2000), CCT (2000) and SIGLE (1980 to 2000). Dissertation abstracts and reference lists of articles were checked and researchers were contacted.

SELECTION CRITERIA

Randomised studies with no more than 20% loss to follow-up, lasting at least three months and involving healthy adults comparing dietary advice with no advice or minimal advice. Trials involving children, trials to reduce weight or those involving supplementation were excluded.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial quality and extracted data. Study authors were contacted for additional information.

MAIN RESULTS

Forty-four trials with 52 intervention arms (comparisons) comparing dietary advice with no advice were included in the review; 18,175 participants or clusters were randomised. Twenty-nine of the 44 included trials were conducted in the USA. Dietary advice reduced total serum cholesterol by 0.15 mmol/L (95% CI 0.06 to 0.23) and LDL cholesterol by 0.16 mmol/L (95% CI 0.08 to 0.24) after 3 to 24 months. Mean HDL cholesterol levels and triglyceride levels were unchanged. Dietary advice reduced blood pressure by 2.61 mm Hg systolic (95% CI 1.31 to 3.91) and 1.45 mm Hg diastolic (95% CI 0.68 to 2.22) and 24-hour urinary sodium excretion by 40.9 mmol (95% CI 25.3 to 56.5) after 3 to 36 months but there was heterogeneity between trials for the latter outcome. Three trials reported plasma antioxidants, where small increases were seen in lutein and β-cryptoxanthin, but there was heterogeneity in the trial effects. Self-reported dietary intake may be subject to reporting bias, and there was significant heterogeneity in all the following analyses. Compared to no advice, dietary advice increased fruit and vegetable intake by 1.18 servings/day (95% CI 0.65 to 1.71). Dietary fibre intake increased with advice by 6.5 g/day (95% CI 2.2 to 10.82), while total dietary fat as a percentage of total energy intake fell by 4.48% (95% CI 2.47 to 6.48) with dietary advice, and saturated fat intake fell by 2.39% (95% CI 1.4 to 3.37).Two trials analysed incident cardiovascular disease (CVD) events (TOHP I/II). Follow-up was 77% complete at 10 to 15 years after the end of the intervention period and estimates of event rates lacked precision but suggested that sodium restriction advice probably led to a reduction in cardiovascular events (combined fatal plus non-fatal events) plus revascularisation (TOHP I hazards ratio (HR) 0.59, 95% CI 0.33 to 1.08; TOHP II HR 0.81, 95% CI 0.59 to 1.12).

AUTHORS' CONCLUSIONS

Dietary advice appears to be effective in bringing about modest beneficial changes in diet and cardiovascular risk factors over approximately 12 months, but longer-term effects are not known.

Multiple chronic conditions: diabetes associated with comorbidity and shared risk factors using CDC WEAT and SAS analytic tools

BACKGROUND

Multiple chronic conditions (MCCs) are significant public health problems receiving much attention, and rightly so, because of the substantial morbidity, mortality, and cost burden.

OBJECTIVES

To report the prevalence of selected frequent MCCs with shared risk factors that are leading causes of death; and to quantify the association between diabetes and its comorbidity and shared risk factors.

METHODS

This is a cross-sectional study of 9172 participants in Pennsylvania's 2009 Behavioral Risk Factor Surveillance System (BRFSS). Centers for Disease Control and Prevention's Web Enabled Analysis Tool (WEAT) and SAS Proc Survey were used for all analyses, to account for BRFSS's multistage complex survey design and sample weights.

RESULTS

SAS estimated prevalence among ≥35-year-olds were as follows: diabetes (11.9%), heart disease (9.5%), stroke (3.3%), diabetes and heart disease (2.9%), diabetes and stroke (1.0%), heart disease and stroke (1.1%), and diabetes, heart disease, and stroke (0.4%). Adults ≥35 years old with the following characteristics were more likely to have diabetes when self-reporting: obese (adjusted odds ratio [ORAdj] = 4.63, 95% confidence interval [95% CI] = 3.41-6.30); low income (<$15 000 ORAdj = 2.85, 95% CI = 1.90-4.27; $15 000-$24 999 ORAdj = 2.07, 95% CI = 1.50-2.86; $25 000-$34 999 ORAdj = 2.06, 95% CI = 1.47-2.88; $35 000-$49 999 ORAdj = 1.51, 95% CI = 1.08-2.12); elderly ≥65 years old (ORAdj = 2.84, 95% CI = 1.76-4.56); non-Hispanic black (ORAdj = 2.54, 95% CI = 1.08-6.00); overweight (ORAdj = 1.99, 95% CI = 1.47-2.68); heart disease (ORAdj = 1.94, 95% CI = 1.47-2.56); 45 to 64 years old (ORAdj = 1.88 95%, CI = 1.21-2.93); hypertension (ORAdj = 1.78, 95% CI = 1.39-2.29); stroke (ORAdj = 1.62, 95% CI = 1.05-2.50); high cholesterol (ORAdj = 1.49, 95% CI = 1.18-1.88); physically inactive (ORAdj = 1.33 95% CI = 1.06-1.67); and men (ORAdj = 1.32, 95% CI = 1.04-1.67).

CONCLUSION

Adults with comorbidity and risk factors were 1.3 to 4.6 times more likely to have diabetes, with obesity consistently the strongest risk factor. WEAT's limitations are the predefined categories, inability to restrict to specific age groups and to estimate the prevalence of >2 MCCs. WEAT has considerable potential to advance evidence-based primary care practice and community health programs, such as state-wide programs that target obesity and physical inactivity. The robust capability of SAS to calculate MCC prevalence and adjusted associations with risk factors provides the fundamentals for developing and evaluating primary care services and community health programs.

The Role of Health Systems in Obesity Management and Prevention: Problems and Paradigm Shifts

This paper provides an overview of a new section of Current Obesity Reports, called Health Services and programs. This new section seeks to better understand the problems within health systems around obesity management and prevention and to discuss the latest research on solutions. There are few health system issues that are quite as controversial as obesity and there remain several key problems inherent within existing obesity management and prevention approaches that necessitate the adoption of new paradigms and practices. Beginning with articles on addressing weight bias and stigma in health professional training, promoting new models of weight management provision, reviewing the role of regulation and generating an understanding of obesity through a complex systems lens, this new section will encourage readers to better address the challenging problems in obesity management and in doing so, overcome the 'paradigm paralysis' that has characterized the last few decades of obesity research and practice.

Training practitioners to deliver opportunistic multiple behaviour change counselling in primary care: a cluster randomised trial

OBJECTIVES

To evaluate the effect of training primary care health professionals in behaviour change counselling on the proportion of patients self reporting change in four risk behaviours (smoking, alcohol use, exercise, and healthy eating).

DESIGN

Cluster randomised trial with general practices as the unit of randomisation.

SETTING

General practices in Wales.

PARTICIPANTS

53 general practitioners and practice nurses from 27 general practices (one each at all but one practice) recruited 1827 patients who screened positive for at least one risky behaviour.

INTERVENTION

Behaviour change counselling was developed from motivational interviewing to enable clinicians to enhance patients' motivation to change health related behaviour. Clinicians were trained using a blended learning programme called Talking Lifestyles.

MAIN OUTCOME MEASURES

Proportion of patients who reported making beneficial changes in at least one of the four risky behaviours at three months.

RESULTS

1308 patients from 13 intervention and 1496 from 14 control practices were approached: 76% and 72% respectively agreed to participate, with 831 (84%) and 996 (92%) respectively screening eligible for an intervention. There was no effect on the primary outcome (beneficial change in behaviour) at three months (362 (44%) v 404 (41%), odds ratio 1.12 (95% CI 0.90 to 1.39)) or on biochemical or biometric measures at 12 months. More patients who had consulted with trained clinicians recalled consultation discussion about a health behaviour (724/795 (91%) v 531/966 (55%), odds ratio 12.44 (5.85 to 26.46)) and intended to change (599/831 (72%) v 491/996 (49%), odds ratio 2.88 (2.05 to 4.05)). More intervention practice patients reported making an attempt to change (328 (39%) v 317 (32%), odds ratio 1.40 (1.15 to 1.70)), a sustained behaviour change at three months (288 (35%) v 280 (28%), odds ratio 1.36 (1.11 to 1.65)), and reported slightly greater improvements in healthy eating at three and 12 months, plus improved activity at 12 months. Training cost £1597 per practice.

DISCUSSION

Training primary care clinicians in behaviour change counselling using a brief blended learning programme did not increase patients reported beneficial behaviour change at three months or improve biometric and a biochemical measure at 12 months, but it did increase patients' recollection of discussing behaviour change with their clinicians, intentions to change, attempts to change, and perceptions of having made a lasting change at three months. Enduring behaviour change and improvements in biometric measures are unlikely after a single routine consultation with a clinician trained in behaviour change counselling without additional intervention.

Obesity, lifestyle risk-factors, and health service outcomes among healthy middle-aged adults in Canada

Background

The extent to which uncomplicated obesity among an otherwise healthy middle-aged population is associated with higher longitudinal health-care expenditures remains unclear.

Methods

To examine the incremental long-term health service expenditures and outcomes associated with uncomplicated obesity, 9398 participants of the 1994–1996 National Population Health Survey were linked to administrative data and followed longitudinally forward for 11.5 years to track health service utilization costs and death. Patients with pre-existing heart disease, those who were 65 years of age and older, and those with self-reported body mass indexes of <18.5 kg/m² at inception were excluded. Propensity-matching was used to compare obesity (+/− other baseline risk-factors and lifestyle behaviours) with normal-weight healthy controls. Cost-analyses were conducted from the perspective of Ontario’s publicly-funded health care system.

Results

Obesity as an isolated risk-factor was not associated with significantly higher health-care costs as compared with normal weight matched controls (Canadian $8,294.67 vs. Canadian $7,323.59, P = 0.27). However, obesity in combination with other lifestyle factors was associated with significantly higher cumulative expenditures as compared with normal-weight healthy matched controls (CAD$14,186.81 for those with obesity + 3 additional risk-factors vs. CAD$7,029.87 for those with normal BMI and no other risk-factors, P < 0.001). The likelihood that obese individuals developed future diabetes and hypertension also rose markedly when other lifestyle factors, such as smoking, physical inactivity and/or psychosocial distress were present at baseline.

Conclusions

The incremental health-care costs associated with obesity was modest in isolation, but increased significantly when combined with other lifestyle risk-factors. Such findings have relevance to the selection, prioritization, and cost-effective targeting of therapeutic lifestyle interventions.

Comparative effectiveness research in lung diseases and sleep disorders: recommendations from the National Heart, Lung, and Blood Institute workshop

The Division of Lung Diseases of the National Heart, Lung, and Blood Institute (NHLBI) held a workshop to develop recommendations on topics, methodologies, and resources for comparative effectiveness research (CER) that will guide clinical decision making about available treatment options for lung diseases and sleep disorders. A multidisciplinary group of experts with experience in efficacy, effectiveness, implementation, and economic research identified (a) what types of studies the domain of CER in lung diseases and sleep disorders should include, (b) the criteria and process for setting priorities, and (c) current resources for and barriers to CER in lung diseases. Key recommendations were to (1) increase efforts to engage stakeholders in developing CER questions and study designs; (2) invest in further development of databases and other infrastructure, including efficient methods for data sharing; (3) make full use of a broad range of study designs; (4) increase the appropriate use of observational designs and the support of methodologic research; (5) ensure that committees that review CER grant applications include persons with appropriate perspective and expertise; and (6) further develop the workforce for CER by supporting training opportunities that focus on the methodologic and practical skills needed.

Lightening the load? A systematic review of community pharmacy-based weight management interventions

The extent to which community pharmacies can increase capacity for weight management is unknown. Thus, the objective of the present paper was to evaluate the effectiveness and cost-effectiveness of community pharmacy weight management interventions. This paper used a design of systematic review and narrative synthesis. Electronic databases (1999-2009) were searched, including Medline, EMBASE, CINAHL and Pharm-line. Weight management studies in community pharmacies were eligible for the inclusion criteria. All languages and study designs were considered. Outcome measures included body weight or anthropometry (at baseline and at least one follow-up time point). Data were extracted through independent, duplicate data extraction and quality assessment. As a result, 10 studies were included, totalling 2,583 service users and 582 pharmacies from the USA, the UK, Switzerland, Spain and Denmark. One was a randomized controlled trial of a meal-replacement versus a reduced calorie diet. A non-randomized controlled before and after study compared community pharmacist treatment using Orlistat with usual care. Eight studies were uncontrolled. Five studies described behaviour change techniques. Long-term (12 months) mean weight loss measured in three studies ranged from 1.1 to 4.1 kg. Four uncontrolled studies reported statistically significant weight loss. No study reported economic evaluations. Currently, there is insufficient evidence for the effectiveness and cost-effectiveness of community pharmacy-based weight management initiatives to support investment in their provision.
