BACKGROUND:Type 2 diabetes mellitus (DM) affects 9.4% of US adults and children, while another 33.9% of Americans are at risk of DM. Health care institutions face many barriers to systematically delivering the preventive care needed to decrease DM incidence. Community health workers (CHWs) may, as frontline public health workers bridging clinic and community, help overcome these challenges. This paper presents the protocol for a pragmatic, cluster-randomized trial integrating CHWs into two primary care clinics to support DM prevention for at-risk patients. METHODS:The trial will randomize 15 care teams, stratified by practice site (Bellevue Hospital and Manhattan VA), totaling 56 primary care physicians. The study cohort will consist of ~ 2000 patients who are 18-75 years of age, actively enrolled in a primary care team, able to speak English or Spanish, and have at least one glycosylated hemoglobin (HbA1c) result in the prediabetic range (5.7-6.4%) since 2012. Those with a current DM diagnosis or DM medication prescription (other than metformin) are ineligible. The intervention consists of four core activities - setting health goals, health education, activation for doctor's appointments, and referrals to DM prevention programs - adjustable according to the patient's needs and readiness. The primary outcome is DM incidence. Secondary outcomes include weight loss, HbA1C, and self-reported health behaviors. Clinical variables and health behaviors will be obtained through electronic medical records and surveys, respectively. Implementation outcomes, namely implementation fidelity and physicians' perspectives about CHW integration into the clinic, will be assessed using interviews and CHW activity logs and analyzed for the influence of moderating organizational factors. DISCUSSION/CONCLUSIONS:This is the first rigorous, pragmatic trial to test the effectiveness of integrating CHWs into primary care for DM prevention reaching a population-based sample. Our study's limitations include language-based eligibility and the use of HbA1c as a measure of DM risk. It will measure both clinical and implementation outcomes and potentially broaden the evidence base for CHWs and patient-centered medical home implementation. Further, the intervention's unique features, notably patient-level personalization and referral to existing programs, may offer a scalable model to benefit patients at-risk of DM.

BACKGROUND: New York City (NYC) is currently home to the largest Bangladeshi population in the United States (US) at approximately 62,000 individuals. The high prevalence of Type 2 diabetes mellitus (T2DM) among Bangladeshis has been well documented in Bangladesh, as well as in Canada and the United Kingdom (UK). However, little is known about the diabetes prevalence and management practices of US Bangladeshis. This paper describes the protocol for a Community Health Worker (CHW) intervention to improve diabetic management and control among Bangladeshis with diabetes in NYC. METHODS/DESIGN: For a two-arm, randomized controlled trial (RCT), investigators will recruit a sample of 256 participants, all of whom are 1) of Bangladeshi descent, 2) residing in NYC, 3) diagnosed with T2DM and a recent Hemoglobin A1c (HbA1c) of >/= 6.5, and 4) between the ages of 21-85. The treatment group receives a six-month CHW-led intervention consisting of five monthly group educational sessions, two one-on-one visits, and follow-up phone calls as needed from a CHW. The control group receives an introductory educational session only. Primary and secondary outcomes include clinical and behavioral measures, such as HbA1c and weight change, access to and utilization of care (i.e. appointment keeping and use of specialty care), and knowledge and practice of physical activity and healthful eating. Additionally, information regarding CHW characteristics, the processes and mechanisms for influencing healthful behavior change, and fidelity of the intervention are collected. Outcomes are measured at Baseline, 3-Months, 6-Months for both groups, and at 12-Months for the treatment group. DISCUSSION: To our knowledge, this study represents the first attempt to document the efficacy of T2DM management strategies in the NYC Bangladeshi population. Thus, future qualitative and quantitative findings of the submitted protocol will fill an important gap in the health disparities literature. TRIAL REGISTRATION: NCT02041598.

Purpose The purpose of this study is to explore the impact and feasibility of a pilot Community Health Worker (CHW) intervention to improve diabetes management among Bangladeshi-American individuals with type 2 diabetes living in New York City. Methods Participants were recruited at clinic- and community-based venues. The intervention consisted of 6 monthly, CHW-facilitated group sessions on topics related to management of diabetes. Surveys were collected at baseline and follow-up time points. Study outcomes included clinical, behavioral, and satisfaction measures for participants, as well as qualitative measures from CHWs. Results Improvements were seen in diabetes knowledge, exercise and diet to control diabetes, frequency of checking feet, medication compliance, and self-efficacy of health and physical activity from baseline to 12 months. Additionally, there were decreases in A1C, weight, and body mass index. Program evaluation revealed a high acceptability of the intervention, and qualitative findings indicated that CHWs helped overcome barriers and facilitated program outcomes through communal concordance, trust, and leadership. Conclusions The intervention demonstrated high acceptability and suggested efficacy in improving diabetes management outcomes among Bangladeshi immigrants in an urban setting. The US Bangladeshi population will continue to increase, and given the high rates of diabetes, as well as linguistic and economic barriers faced by this community, effective and culturally tailored health interventions are needed to overcome barriers and provide support for diabetes management.

STUDY OBJECTIVE: Our objective is to determine whether a point-of-care intervention that navigates willing, low-acuity patients from the emergency department (ED) to a Primary Care Clinic will increase future primary care follow-up. METHODS: We conducted a quasi-experimental trial at an urban safety net hospital. Adults presenting to the ED for select low-acuity problems were eligible. Patients were excluded if arriving by emergency medical services, if febrile, or if the triage nurse believed they required ED care. We enrolled 965 patients. Navigators escorted a subset of willing participants to the Primary Care Clinic (in the same hospital complex), where they were assigned a personal physician, were given an overview of clinic services, and received same-day clinic care. The primary outcome was Primary Care Clinic follow-up within 1 year of the index ED visit among patients having no previous primary care provider. RESULTS: In the bivariate intention-to-treat analysis, 50.3% of intervention group patients versus 36.9% of control group patients with no previous primary care provider had at least 1 Primary Care Clinic follow-up visit in the year after the intervention. In the multivariable analysis, the absolute difference in having at least 1 Primary Care Clinic follow-up for the intervention group compared with the control group was 9.3% (95% confidence interval 2.2% to 16.3%). There was no significant difference in the number of future ED visits. CONCLUSION: A point-of-care intervention offering low-acuity ED patients the opportunity to alternatively be treated at the hospital's Primary Care Clinic resulted in increased future primary care follow-up compared with standard ED referral practices.
