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

[Strategies for the prevention and non-pharmacological treatment of obesity. Models of care]

The prevalence of obesity has increased in recent years worldwide. In this context, strategies for management obesity in primary care are essential. The first step in the treatment of obesity are lifestyle intervention programs. The three pillars of these programs, ideally of high intensity (high frequency of visits), are dietary intervention, exercise and behavioral therapy. There is no universal model of care for patients with obesity, but it must take into account key aspects, such as facilitating the access and adherence of the patient and a multidisciplinary and coordinated care among professionals at different levels of healthcare. The components of the model of care and its format should be defined according to the resources available and the characteristics of the population to be treated.

Healthcare professionals' experiences of interprofessional collaboration in patient education: A systematic review

OBJECTIVES

This study explores interprofessional collaboration amongst healthcare professionals in patient education.

METHODS

A systematic review was conducted. A search in seven databases was conducted from 2011 to 2022 and screened against the inclusion criteria. Quality appraisal was done independently by two reviewers. Studies were extracted and synthesised using the data-based convergent synthesis design.

RESULTS

Twenty-one studies were included. Five themes on factors affecting interprofessional collaboration in patient education emerged: 1) role clarification, 2) communication infrastructure, 3) shared space for collaboration, 4) interprofessional trust, and 5) organisational support.

CONCLUSION

Findings highlighted the importance of developing trustful relationships within the multidisciplinary team in delivering patient education. Channels for additional infrastructural support, guidelines and training in patient education delivery is required. Future research could explore patients' perspectives on how their learning needs in patient education may be optimised through a multidisciplinary approach.

PRACTICE IMPLICATIONS

Healthcare leaders could promote shared goals within the team by facilitating a common space and time for interprofessional team rounding, and by developing shared patient education resources and documentation processes. Interprofessional education focusing on the delivery of team-based patient education could be implemented to foster understanding of the interdependent role of multidisciplinary healthcare professionals.

In it for the long haul: the complexities of managing overweight in family practice: qualitative thematic analysis from the Health eLiteracy for Prevention in General Practice (HeLP-GP) trial

BACKGROUND

Australia has one of the highest rates of overweight and obesity in the developed world, and this increasing prevalence and associated chronic disease morbidity reinforces the importance of understanding the attitudes, views, and experiences of patients and health providers towards weight management interventions and programs. The purpose of this study was to investigate patients, family practitioners and family practice nurses' perceptions and views regarding the receipt or delivery of weight management within the context of the HeLP-GP intervention.

METHODS

A nested qualitative study design including semi-structured interviews with family practitioners (n = 8), family practice nurses (n = 4), and patients (n = 25) attending family practices in New South Wales (n = 2) and South Australia (n = 2). The patient interviews sought specific feedback about each aspect of the intervention and the provider interviews sought to elicit their understanding and opinions of the strategies underpinning the intervention as well as general perceptions about providing weight management to their patients. Interviews were recorded and transcribed verbatim, and coding and management conducted using NVivo 12 Pro. We analysed the interview data using thematic analysis.

RESULTS

Our study identified three key themes: long-term trusting and supportive relationships (being 'in it for the long haul'); initiating conversations and understanding motivations; and ensuring access to multi-modal weight management options that acknowledge differing levels of health literacy. The three themes infer that weight management in family practice with patients who are overweight or obese is challenged by the complexity of the task and the perceived motivation of patients. It needs to be facilitated by positive open communication and programs tailored to patient needs, preferences, and health literacy to be successful.

CONCLUSIONS

Providing positive weight management in family practice requires ongoing commitment and an open and trusting therapeutic relationship between providers and patients. Behaviour change can be achieved through timely and considered interactions that target individual preferences, are tailored to health literacy, and are consistent and positive in their messaging. Ongoing support of family practices is required through funding and policy changes and additional avenues for referral and adjunctive interventions are required to provide comprehensive weight management within this setting.

Contextually Appropriate Tools and Solutions to Facilitate Healthy Eating Identified by People with Type 2 Diabetes

Type 2 diabetes (T2D) is a complex, multifaceted disease and its treatment involves lifestyle intervention (LI) programs that participants may find difficult to adopt and maintain. The objective of this study is to understand the lived experiences of participants with T2D regarding healthy eating behavior change, in order to identify and incorporate relevant information, skills, and educational approaches into LI programs. An explorative qualitative study was undertaken. Purposeful sampling was used to recruit 15 participants. One-on-one, semi-structured, open-ended, and in-depth interviews were conducted. An essentialist paradigm was adopted to accurately report the experiences, meaning, and reality of participants. An inductive approach was used to analyze the data. Participants reported that being diagnosed and living with T2D could be overwhelming, and their ability to manage was influenced by health care providers (HCP), family, and individual context. Many experienced a loop of “good–bad” eating behaviors. Participants expressed desires for future diabetes management that would include program content (nutrition, physical activity, mental health, foot care, and consequences of T2D), program features (understand context, explicit information, individualized, hands-on learning, applicable, realistic, incremental, and practical), program components (access to multidisciplinary team, set goals, track progress and be held accountable, one-on-one sessions, group support, maintenance/follow-up), and policy change. In conclusion, the results of this study indicate that T2D management requires more extensive, comprehensive, and ongoing support, guided by the individual participant.

A pan-Canadian study of registered dietitians' perceptions and experiences of interprofessional collaboration

Little is known about Canadian dietitians' perceptions and experiences of interprofessional collaboration. To address this knowledge gap, a cross-sectional online survey was administered to registered dietitians in Canada. Quantitative data was analyzed in SPSS using descriptive and inferential statistics, while thematic analysis was used for open-text responses. A total of N = 469 registered dietitians representing 10 provinces participated in the study. Results showed a significant difference (p < .001) between the frequency with which dietitians collaborated with other health and social care providers and their desired frequency, with 61.0% indicating they wanted more frequent collaboration. A majority of dietitians (59.2%) had negative views of interprofessional interactions. Nearly all respondents felt there is a need to raise better awareness about the dietetic profession (95.4%) and that dietitians are underutilized in the world of healthcare (92.5%). On three measures, a majority of participants (ranging from 65.6% to 81.5%) reported that their dietetic training helped equip them for interprofessional collaboration. Insufficient time/availability was the obstacle to interprofessional collaboration cited most frequently by dietitians. Results suggest that interprofessional collaboration is an area in need of attention in the Canadian dietetic profession, as well as with health and social care providers who work with dietitians. The study's findings point to potential areas for improvement.

A systematic review and thematic synthesis of qualitative studies exploring GPs' and nurses' perspectives on discussing weight with patients with overweight and obesity in primary care

Guidelines and evidence suggest primary care clinicians should give opportunistic interventions to motivate weight loss, but these rarely occur in practice. We sought to examine why by systematically reviewing qualitative research examining general practitioners' ('GPs') and nurses' views of discussing weight with patients. We systematically searched English language publications (1945-2018) to identify qualitative interview and focus group studies. Thematic methods were used to synthesise the findings from these papers. We synthesised the studies by identifying second-order themes (explanations offered by the original researchers) and third-order constructs (new explanations which went beyond those in the original publications). Quality assessment using the Joanna Briggs checklist was undertaken. We identified 29 studies (>601 GPs, nurses and GP trainees) reporting views on discussing weight with patients. Key second-order themes were lack of confidence in treatments and patients' ability to make changes, stigma, interactional difficulty of discussing the topic and a belief of a wider societal responsibility needed to deal with patients with overweight and obesity. The third-order analytical theme was that discussions about weight were not a priority, and other behavioural interventions, including those relating to smoking, often took precedent. GPs and nurses reported that noting body mass index measurements at every consultation alongside a framework to deliver interventions would likely increase the frequency and perceived efficacy of behavioural weight interventions. GPs and nurses acknowledge the importance of obesity as a health issue, but this is insufficient, particularly amongst GPs, for them to construe this as a medical problem to address with patients in consultations. Strategies to implement clinical guidelines need to make tackling obesity a clinical priority. Training to overcome interactional difficulties, regular weighing of patients and changing expectations and understanding of weight loss interventions are also probably required.

Dietitians' Perspectives on the Impact of Multidisciplinary Teams and Electronic Medical Records on Dietetic Practice for Weight Management

Purpose: To understand the perception of dietitians regarding the effects of multidisciplinary settings and Electronic Health Records (EHRs) on their dietetic practice for weight management. Methods: Individual semi-structured interviews were conducted with 14 dietitians working in multidisciplinary settings in Ontario. All interviews were audio recorded and transcribed verbatim. Two researchers coded the data independently using a thematic analysis approach. All themes emerged inductively and were refined iteratively. Results: Most dietitians believed that working in a multidisciplinary setting allowed for interprofessional collaboration and time-effective referrals. Multidisciplinary clinics were perceived to improve patient care due to convenient scheduling, consistent messaging, and ongoing support. However, some dietitians reported instances of conflicting approaches and beliefs regarding weight management across health professionals. Dietitians suggested ways to address these conflicting approaches through clinical meetings and education. EHRs were perceived to allow for collaboration through facilitated communication and knowledge exchange; however, lack of interoperability between EHR platforms across different types of health care settings was perceived to be a barrier for optimal care. Conclusions: Overall, multidisciplinary settings were perceived to positively impact dietitians' practices for weight management as they allow for interprofessional collaboration. Consistency in health messaging across health professionals should be emphasized through knowledge exchange.

Acceptability and feasibility of weight management programmes for adults with severe obesity: a qualitative systematic review

OBJECTIVES

To improve our understanding of the acceptability of behavioural weight management programmes (WMPs) for adults with severe obesity.

DESIGN

A systematic review of qualitative evidence.

DATA SOURCES

Medline, Embase, PsycINFO, CINAHL, SCI, SSCI and CAB abstracts were searched from 1964 to May 2017.

ELIGIBILITY CRITERIA

Papers that contained qualitative data from adults with body mass index (BMI) ≥35 kg/m² (and/or the views of providers involved in their care) and considered issues about weight management.

DATA EXTRACTION AND SYNTHESIS

Two reviewers read and systematically extracted data from the included papers which were compared, and contrasted according to emerging issues and themes. Papers were appraised for methodological rigour and theoretical relevance using Toye's proposed criteria for quality in relation to meta-ethnography.

RESULTS

33 papers met our inclusion criteria from seven countries published 2007-2017. Findings were presented from a total of 644 participants and 153 programme providers. Participants described being attracted to programmes that were perceived to be novel or exciting, as well as being endorsed by their healthcare provider. The sense of belonging to a group who shared similar issues, and who had similar physiques and personalities, was particularly important and seemed to foster a strong group identity and related accountability. Group-based activities were enjoyed by many and participants preferred WMPs with more intensive support. However, some described struggling with physical activities (due to a range of physical comorbidities) and not everyone enjoyed group interaction with others (sometimes due to various mental health comorbidities). Although the mean BMI reported across the papers ranged from 36.8 to 44.7 kg/m², no quotes from participants in any of the included papers were linked to specific detail regarding BMI status.

CONCLUSIONS

Although group-based interventions were favoured, people with severe obesity might be especially vulnerable to physical and mental comorbidities which could inhibit engagement with certain intervention components.

To initiate the conversation - Public health nurses' experiences of working with obesity in persons with mobility disability

Aim

Developing a theory explaining how public health nurses accomplish and adapt counselling in lifestyle habits to decrease obesity in people with mobility disability.

Design

Empirical research ‐ qualitative.

Method

Classic grounded theory with face‐to‐face interviews, 2017–2018, using inductive approach to understand public health nurses' intervening experiences with obesity patients.

Results

To initiate the conversation emerged as the main concern meaning having difficulties initiating conversations about obesity with patients. Public health nurses’ facilitators to communicate lifestyle changes emerged as the pattern generating the theory, which consists of the categories; person‐centeredness in the situation, experience and knowledge, strengthening conditions, access to other professionals and prioritization in everyday work.

Conclusions

Public health nurses hesitate to raise topics of obesity in patients with mobility disability. They advocate increased integration with lifestyle changes in everyday work including multi‐professional cooperation. The implication is testing the emerged theory at primary health care centres.

Impact

Obesity is more common in people with mobility disability than in those without. There is a need to understand how public health nurses adapt counselling in lifestyle habits. Public health nurses hesitate to talk about obesity with patients in fear of offending anyone. Public health nurses did not distinguish between patients with or without mobility disability. Several facilitators could be helpful initiating conversation with the patients. Public health nurses need more time and resources to facilitate conversation with patients with mobility disability to counsel lifestyle changes.

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.

Implications of interprofessional primary care team characteristics for health services and patient health outcomes: A systematic review with narrative synthesis

Interprofessional primary care (IPPC) teams are promoted as an alternative to single profession physician practices in primary care with focus on preventive care and chronic disease management. Characteristics of teams can have an impact on their performance. We synthesized quantitative, qualitative or mixed-methods evidence addressing the design of IPPC teams. We searched Ovid MEDLINE, Embase, CINAHL, and PAIS using search terms focused on IPPC teams. Studies were included if they discussed the influence of team structure, organization, financial arrangements, or policies and procedures, or either health care processes or outputs, health outcomes, or costs, and were conducted in Australia, Canada, the United Kingdom or New Zealand between 2003 and 2016. We screened 11,707 titles, 5366 abstracts, and selected 77 full text articles (38 qualitative, 31 quantitative and 8 mixed-methods). Literature focused on the implications of team characteristics on team processes, such as teamwork, collaboration, or satisfaction of patients or providers. Despite heterogeneity of contexts, some trends are observable: shared space, common vision and goals, clear definitions of roles, and leadership as important to good teamwork. The impacts of these on health care outputs or patient health are not clear. To move the state of knowledge beyond perception of what works well for IPPC teams, researchers should focus on quantitative causal inference about the linkages between team characteristics and patient health.

Facing obesity: Adapting the collaborative deliberation model to deal with a complex long-term problem

OBJECTIVE

Care communication about obesity needs to respond to the complex biopsychosocial processes that affect weight and health. The collaborative deliberation model conceptualizes interpersonal work that underpins empathic communication and shared decision-making. The goal of this study was to elucidate how primary care practitioners can use the model to achieve shared obesity assessment and care planning.

METHODS

This qualitative study used direct observation of clinical encounters with twenty patients with obesity sampled for maximum variation in context, semi-structured patient and provider interviews, patient journals and two follow-up interviews over eight weeks. Themes were compared to the original model.

RESULTS

We identified five processes that may be relevant for collaborative deliberation about obesity in addition to the original model: (1) Exploring the story, (2) Reframing the story, (3) Co-constructing a new story, (4) Choosing a priority, and (5) Experimenting with alternatives.

CONCLUSIONS

We propose an enhanced collaborative deliberation model for obesity that describes the interpersonal work needed before and after deliberation about preferences and courses of action.

PRACTICE IMPLICATIONS

The enhanced model can support clinicians in achieving meaningful conversations about obesity and complex chronic disease resulting in care plans that are responsive to and achievable in the patient's lifeworld.

Practice patterns of nurse practitioners related to weight management in primary care

BACKGROUND AND OBJECTIVES

Obesity prevalence rates for adults are at an all-time high. This systematic review of the literature aimed to examine the practice patterns of nurse practitioners (NPs) related to weight management in primary care and recommend future areas of research as it relates to the diagnosis and management of patients with obesity by NPs.

DATA SOURCES

The databases CINAHL PLUS with Full Text, Cochrane Central Register of Controlled Trials, ERIC, MEDLINE, PsycINFO, and SPORTDiscuss were searched.

CONCLUSIONS

The initial search resulted in 169 articles. Fifteen peer-reviewed articles from 13 studies were included in the analysis. Four themes emerged from the analysis: approach to practice; the practitioner's role within the interdisciplinary team; communication; and resources and tools.

IMPLICATIONS FOR PRACTICE

This review was conducted to better understand the challenges and facilitators to the management of patients with obesity in primary care. Future research between NPs and variables related to obesity are necessary to further identify areas for education, training, and policy development.

Challenges faced by Canadian primary health care nurse practitioners in chronic disease management: A qualitative study among key informants

BACKGROUND AND PURPOSE

The increasing prevalence of chronic diseases is driving health care systems to rethink their operations. Despite numerous studies supporting the advantages of primary health care nurse practitioners (PHCNPs) in chronic disease management, implementing practices that fully use the skills of these practitioners seems impeded in the Canadian province of Québec. This study explores the views of leaders involved in primary health care regarding the contributions PHCNPs can make in chronic disease management and the challenges they face in doing so.

METHODS

Through semistructured interviews, an exploratory descriptive qualitative study was conducted with 20 key informants across Québec who hold a variety of professional positions connected to PHCNPs.

CONCLUSIONS

Primary health care nurse practitioners were perceived to be able to improve self-management support for chronic diseases. In reality, however, PHCNPs are mainly devoting their time to clientele in acute care, and current regulations governing their practices limit their involvement in chronic disease management.

IMPLICATIONS FOR PRACTICE

Integrating PHCNPs offers a unique opportunity for health care settings to redefine the roles of family physicians and registered nurses and to restructure practices toward a chronic disease-oriented system. A clinical manager should be designated to monitor this restructuring process and ensure its success.

Personalizing obesity assessment and care planning in primary care: patient experience and outcomes in everyday life and health

Obesity is a complex, chronic disease, frequently associated with multiple comorbidities. Its management is hampered by a lack of translation of evidence on chronicity and pathophysiology into clinical practice. Also, it is not well understood how to support effective provider-patient communication that adequately addresses patients' personal root causes and barriers and helps them feel capable to take action for their health. This study examined interpersonal processes during clinical consultations, their impacts, and outcomes with the aim to develop an approach to personalized obesity assessment and care planning. We used a qualitative, explorative design with 20 participants with obesity, sampling for maximum variation, to examine video-recorded consultations, patient interviews at three time points, provider interviews and patient journals. Analysis was grounded in a dialogic interactional perspective and found eight key processes that supported patients in making changes to improve health: compassion and listening; making sense of root causes and contextual factors in the patient's story; recognizing strengths; reframing misconceptions about obesity; focusing on whole-person health; action planning; fostering reflection and experimenting. Patient outcomes include activation, improved physical and psychological health. The proposed approach fosters emphatic care relationships and sensible care plans that support patients in making manageable changes to improve health.

Bariatric surgery, lifestyle interventions and orlistat for severe obesity: the REBALANCE mixed-methods systematic review and economic evaluation

BACKGROUND

Adults with severe obesity [body mass index (BMI) of ≥ 35 kg/m2] have an increased risk of comorbidities and psychological, social and economic consequences.

OBJECTIVES

Systematically review bariatric surgery, weight-management programmes (WMPs) and orlistat pharmacotherapy for adults with severe obesity, and evaluate the feasibility, acceptability, clinical effectiveness and cost-effectiveness of treatment.

DATA SOURCES

Electronic databases including MEDLINE, EMBASE, PsycINFO, the Cochrane Central Register of Controlled Trials and the NHS Economic Evaluation Database were searched (last searched in May 2017).

REVIEW METHODS

Four systematic reviews evaluated clinical effectiveness, cost-effectiveness and qualitative evidence for adults with a BMI of ≥ 35 kg/m2. Data from meta-analyses populated a microsimulation model predicting costs, outcomes and cost-effectiveness of Roux-en-Y gastric bypass (RYGB) surgery and the most effective lifestyle WMPs over a 30-year time horizon from a NHS perspective, compared with current UK population obesity trends. Interventions were cost-effective if the additional cost of achieving a quality-adjusted life-year is < £20,000-30,000.

RESULTS

A total of 131 randomised controlled trials (RCTs), 26 UK studies, 33 qualitative studies and 46 cost-effectiveness studies were included. From RCTs, RYGB produced the greatest long-term weight change [-20.23 kg, 95% confidence interval (CI) -23.75 to -16.71 kg, at 60 months]. WMPs with very low-calorie diets (VLCDs) produced the greatest weight loss at 12 months compared with no WMPs. Adding a VLCD to a WMP gave an additional mean weight change of -4.41 kg (95% CI -5.93 to -2.88 kg) at 12 months. The intensive Look AHEAD WMP produced mean long-term weight loss of 6% in people with type 2 diabetes mellitus (at a median of 9.6 years). The microsimulation model found that WMPs were generally cost-effective compared with population obesity trends. Long-term WMP weight regain was very uncertain, apart from Look AHEAD. The addition of a VLCD to a WMP was not cost-effective compared with a WMP alone. RYGB was cost-effective compared with no surgery and WMPs, but the model did not replicate long-term cost savings found in previous studies. Qualitative data suggested that participants could be attracted to take part in WMPs through endorsement by their health-care provider or through perceiving innovative activities, with WMPs being delivered to groups. Features improving long-term weight loss included having group support, additional behavioural support, a physical activity programme to attend, a prescribed calorie diet or a calorie deficit.

LIMITATIONS

Reviewed studies often lacked generalisability to UK settings in terms of participants and resources for implementation, and usually lacked long-term follow-up (particularly for complications for surgery), leading to unrealistic weight regain assumptions. The views of potential and actual users of services were rarely reported to contribute to service design. This study may have failed to identify unpublished UK evaluations. Dual, blinded numerical data extraction was not undertaken.

CONCLUSIONS

Roux-en-Y gastric bypass was costly to deliver, but it was the most cost-effective intervention. Adding a VLCD to a WMP was not cost-effective compared with a WMP alone. Most WMPs were cost-effective compared with current population obesity trends.

FUTURE WORK

Improved reporting of WMPs is needed to allow replication, translation and further research. Qualitative research is needed with adults who are potential users of, or who fail to engage with or drop out from, WMPs. RCTs and economic evaluations in UK settings (e.g. Tier 3, commercial programmes or primary care) should evaluate VLCDs with long-term follow-up (≥ 5 years). Decision models should incorporate relevant costs, disease states and evidence-based weight regain assumptions.

Patient experiences of a lifestyle program for metabolic syndrome offered in family medicine clinics: a mixed methods study

BACKGROUND

Patient perspectives on new programs to manage metabolic syndrome (MetS) are critical to evaluate for possible implementation in the primary healthcare system. Participants' perspectives were sought for the Canadian Health Advanced by Nutrition and Graded Exercise (CHANGE) study, which enrolled 293 participants, and demonstrated 19% reversal of MetS after 1 year. The main purpose of this study was to examine participants' perceptions of their experiences with the CHANGE program, enablers and barriers to change.

METHODS

A convergent parallel mixed methods design combined patients' perspectives collected by questionnaires (n = 164), with insights from focus groups (n = 41) from three sites across Canada. Qualitative data were thematically analyzed using interpretative description. Insights were organized within a socio-ecologic framework.

RESULTS

Key aspects identified by participants included intra-individual factors (personal agency, increased time availability), inter-individual factors (trust, social aspects) and organizational factors (increased mental health support, tailored programs).

CONCLUSION

Results revealed participants' overall support for the CHANGE program, especially the importance of an extended program under the guidance of a family physician along with a skilled and supportive team. Team delivery of a lifestyle program in primary care or family medicine clinics is a complex intervention and use of a mixed methods design was helpful for exploring patient experiences and key issues on enablers and barriers to health behavior change.

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.

Current Weight Management Approaches Used by Primary Care Providers in Six Multidisciplinary Healthcare Settings in Ontario

BACKGROUND

Obesity management in primary care has been suboptimal due to lack of access to allied health professionals, time, and resources.

PURPOSE

To understand the weight management approaches used by primary care providers working in team-based settings and how they assess the most suitable approach for a patient.

METHODS

A total of 20 primary care providers (13 nurse practitioners and 7 family physicians) working in 6 multidisciplinary clinics in Ontario were interviewed. All interviews were recorded, transcribed verbatim, and coded using NVivo qualitative software. Conventional content analysis was used to inductively elucidate codes, which were then clustered into categories.

RESULTS

A referral to on-site programming was the most frequent weight management approach used. The pharmacological approach was underutilized due to adverse side effects and cost to patients. Primary care providers assessed the most suitable weight management approach based on patients': preference, level of motivation, income status and access to resources, body mass index and comorbidities, and previous weight loss attempts. Primary care providers perceived that referring to health professionals and educational resources were the approaches preferred by patients.

CONCLUSIONS

The team-based nature of these clinics allowed for referrals to various on-site professionals and/or programs. Some barriers to pursuing weight management avenues with patients were patient dependent.

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.

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.

The 5As team patient study: patient perspectives on the role of primary care in obesity management

Background

Over 60% of people have overweight or obesity, but only a third report receiving counselling from primary care providers. We explored patients’ perspectives on the role of primary care in obesity management and their experience with existing resources, with a view to develop an improved understanding of this perspective, and more effective management strategies.

Methods

Qualitative study employing semi-structured interviews and thematic analysis, with a sample of 28 patients from a cohort of 255 patients living with obesity and receiving care to support their weight management in a large Primary Care Network of family practices in Alberta.

Results

Four illustrative themes emerged: (1) the patient-physician relationship plays an important role in the adequacy of obesity management; (2) patients have clear expectations of substantive conversations with their primary care team; (3) complex conditions affect weight and patients require assistance tailored to individual obesity drivers; (4) current services provide support in important ways (accessibility, availability, accountability, affordability, consistency of messaging), but are not yet meeting patient needs for individual plans, advanced education, and follow-up opportunities.

Conclusions

Patients have clear expectations that their primary care physician asks them about weight within a supportive therapeutic relationship. They see obesity as a complex phenomenon with multiple drivers. They want their healthcare providers to assess and address their root causes - not simplistic advice to “eat less, move more”. Patients felt that the current services were positive resources, but expressed needs for tailored weight management plans, and longer-term follow-up.

Improving Obesity Prevention and Management in Primary Care in Canada

Obesity is a major risk factor for chronic diseases with significant morbidity, mortality and health care cost. There is concern due to the dramatic increase in overweight and obesity in Canada in the last 20 years. The causes of obesity are multifactorial, with underestimation by patients and healthcare providers of the long-term nature of the condition, and its complexity. Solutions related to prevention and management will require multifaceted strategies involving education, health policy, public health and health systems across the care continuum. We believe that to support such strategies we need to have a strong primary care workforce equipped with appropriate knowledge, skills and attitudes to support persons at risk for, or with, obesity. To achieve this end, significant skills building is required to improve primary care obesity prevention and management efforts. This review will first examine the current state, and then will outline how we can improve.

The role of free fatty acids in the inflammatory and cardiometabolic profile in adolescents with metabolic syndrome engaged in interdisciplinary therapy

The purpose of the present study was to evaluate if interdisciplinary therapy can influence the cardiometabolic and serum free fatty acid profile. The second aim was to evaluate if there is an association between serum free fatty acids, inflammation and cardiometabolic biomarkers in obese adolescents with and without metabolic syndrome submitted to a long-term interdisciplinary therapy. The study involved 108 postpuberty obese adolescents, who were divided according to metabolic syndrome (MetS) diagnosis: MetS (n=32) and Non-MetS (n=76). The interdisciplinary therapy consisted of a 1-year period of nutrition, psychology, physical exercise and clinical support. After therapy, both groups improved metabolic, inflammatory (leptin, adiponectin, leptin/adiponectin ratio, adiponectin/leptin ratio and C-reactive protein) and cardiometabolic profile (PAI-1 and ICAM). Metabolic syndrome prevalence reduced from 28.70% to 12.96%. Both groups reduced myristic acid (C14:0) and increased docosahexaenoic acid (DHA, C22:6n3), heneicosapentaenoic acid (HPA, C21:5n3) and arachidonic acid (C20:4n6). After adjustment for metabolic syndrome and the number of metabolic syndrome parameters, multiple regression analysis showed that changes in VCAM and PAI-1 were negatively associated with changes in cis-linoleic acid (C18:2n6c). Additionally, changes in trans-linoleic acid (C18:2n6t) were also positively associated with these biomarkers. Moreover, leptin and leptin/adiponectin ratio were negatively associated with changes in docosapentaenoic acid (DPA, C22:5n3) and stearidonic acid (SDA, C18:4n3). Adiponectin/leptin ratio was positively associated with docosapentaenoic acid (DPA, C22:5n3). Changes in adiponectin were positively correlated with changes in omega 3, such as heneicosapentaenoic acid (HPA, C21:5n3) and docosapentaenoic acid (DPA, C22:5n3). Results support that interdisciplinary therapy can control inflammatory and cardiometabolic profile in obese adolescents. Moreover, serum fatty acids can be influenced by lifestyle changes and are able to modulate these biomarkers.
