A weight loss intervention delivered by peer coaches in primary care: Rationale and study design of the PROMISE trial.

Primary care offers a familiar and accessible clinical venue for patients with obesity to receive evidence-based lifestyle interventions for weight management. However, there are numerous barriers to the implementation of such programs in primary care, and previous primary care weight loss interventions demonstrate modest and temporary effects. Weight loss treatment delivered within primary care by peer coaches may offer a viable and effective alternative. The purpose of this trial is to test the effects of weight loss treatment that includes ongoing support from a peer coach (i.e., trained, salaried community health workers) as compared to self-directed treatment. Peer coach treatment will be delivered over 18 months and includes a combination of in-person, group-based office visits and individual telephone contacts. This weight loss trial will include 375 adults with obesity (BMI = 30-50 kg/m2) randomized from 10 primary care practices. The primary outcome will be changes in body weight at month 18. Secondary outcomes will include key patient-centered outcomes, including quality-of-life, physical and social functioning, mood, and treatment satisfaction. The cost-effectiveness of the peer coach intervention will also be evaluated. If this novel intervention is effective, it could offer a practical and sustainable approach for the delivery of weight loss treatment in primary care that has the potential to improve clinical outcomes for patients, increase treatment options for primary care providers, and reduce obesity-related healthcare utilization and costs.

Differences in perspectives regarding diabetes management between health care providers and patients.

Chronic conditions such as type 2 diabetes are challenging to manage. This is often due to failure of both the practice of effective diabetes self-care management by the patient and inadequate intervention strategies and follow-up by the health care provider (HCP). The aims of the study are (i) to use a social marketing survey approach to understand the gaps in perceptions between patients with type 2 diabetes and HCPs on diabetes-related topics such as levels of awareness, use and satisfaction with community resources, and perceived barriers to self-management and (ii) to present the results of a public awareness campaign/diabetes management demonstration project (Cities for Life) on change in discordant views between HCPs and patients. The study was conducted as a separate sample pre-post quasiexperimental design study as part of a clinical-community program, Cities for Life in Birmingham, AL. The surveys were administered before (Wave 1 or W1 in 2012) and after (Wave 2 or W2 in 2013) implementation of the Cities for Life program. HCPs (n = 50 and 48) and patients with type 2 diabetes and prediabetes (n = 201 and 204) responded to surveys at W1 and W2, respectively. At both timepoints, HCPs and patients identified diabetes as a major health priority and stated education and information as the most valuable aspects of community-based programs (CBPs). Although 86% of HCPs reported recommending CBPs for lifestyle modification and that their patients frequently participated in CBPs (W1 = 70%; W2 = 82%), fewer patients reported participation (W1 = 31%; W2 = 22%). Patients frequently were not able to name any CBPs for diabetes prevention or treatment (W1 = 45%; W2 = 59%) despite a large proportion perceiving CBPs as valuable (W1 = 41%; W2 = 39%). A substantial percentage of patients reported receiving "a lot of support" from family/friends/or coworkers (W1 = 54%; W2 = 64%; p < .05), but HCPs believed that a much lower proportion of their patients received "a lot of support" (W1 = 0%, W2 = 10%, p < .05). Patients and HCPs independently reported patients' lack of motivation as one of the main barriers to better diabetes care. HCPs and patients reported discordant views regarding two important aspects of diabetes self-management: the use of community resources and the degree of social suppor t received by patients. HCPs overestimated the patients' use of community resources, and underestimated the patients' degree of social support. Trans-disciplinary interventions to address patients' lack of motivation and to engage social support networks may improve communication and mutual understanding about the role and benefits of community resources in diabetes and other chronic disease self-management.

Patient Navigators Connecting Patients to Community Resources to Improve Diabetes Outcomes.

BACKGROUND: Despite the recognized importance of lifestyle modification in reducing risk of developing type 2 diabetes and in diabetes management, the use of available community resources by both patients and their primary care providers (PCPs) remains low. The patient navigator model, widely used in cancer care, may have the potential to link PCPs and community resources for reduction of risk and control of type 2 diabetes. In this study we tested the feasibility and acceptability of telephone-based nonprofessional patient navigation to promote linkages between the PCP office and community programs for patients with or at risk for diabetes. METHODS: This was a mixed-methods interventional prospective cohort study conducted between November 2012 and August 2013. We included adult patients with and at risk for type 2 diabetes from six primary care practices. Patient-level measures of glycemic control, diabetes care, and self-efficacy from medical records, and qualitative interview data on acceptability and feasibility, were used. RESULTS: A total of 179 patients participated in the study. Two patient navigators provided services over the phone, using motivational interviewing techniques. Patient navigators provided regular feedback to PCPs and followed up with the patients through phone calls. The patient navigators made 1028 calls, with an average of 6 calls per patient. At follow-up, reduction in HbA1c (7.8 ± 1.9% vs 7.2 ± 1.3%; P = .001) and improvement in patient self-efficacy (3.1 ± 0.8 vs 3.6 ± 0.7; P < .001) were observed. Qualitative analysis revealed uniformly positive feedback from providers and patients. CONCLUSIONS: The patient navigator model is a promising and acceptable strategy to link patient, PCP, and community resources for promoting lifestyle modification in people living with or at risk for type 2 diabetes.

Agromedicine focus group: cooperative extension agents and medical school instructors plan farm field trips for medical students.

BACKGROUND: Current medical education policy seeks to address the health care needs of underserved populations, among whom are individuals associated with agriculture. METHODS: This paper describes a focus group approach to planning farm field trips whereby medical students accompany agricultural extension agents to study the personal, occupational, and environmental health concerns of farmers. RESULTS: The resulting plan joins a state's cooperative extension system, medical school, and farm community in partnership to provide an experiential approach to agricultural medicine and rural health education. CONCLUSION: The planning exercise and the field trips are successful examples of agromedicine, a partnership approach to preventive agricultural medicine involving professionals in medicine and in agriculture.
