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.

Background: Having a usual source of primary care is known to improve health. Currently only two-thirds of ED patients have a usual source of care outside the ED, far short of Healthy People 2020's target of 84%. Prior attempts to link ED patients with primary care have had mixed results. Objectives: To determine if an intervention directly linking low-acuity patients with a primary care clinic at the time of an ED visit could lead to future primary care linkage. Methods: DESIGN: Pseudo-randomized controlled trial. SETTING: Urban safety-net hospital. SUBJECTS: Adults presenting to the ED 1/07-1/08 for select problems a layperson would identify as low-acuity. Patients were excluded if they arrived by EMS, had a PCP outside our hospital, were febrile, or the triage nurse felt they needed ED care. Consecutive patients were enrolled weekday business hours when the primary care clinic was open. Patients were assigned to usual care in the ED if a provider was ready to see them before they had completed the baseline study survey. Otherwise they were offered the intervention if a clinic slot was available. INTERVENTION: Patients agreeing to the intervention were escorted to a primary care clinic in the same hospital building. They were assigned a personal physician and given an overview of clinic services. A patient navigator ensured patients received timely same-day care. Intervention group patients could refuse the intervention and instead remain in the ED for care. Both clinic and ED patients were given follow-up clinic appointments, or a phone number to call for one, as per usual provider practice. ANALYSIS: The main outcome measure was primary care linkage, defined as having one or more primary care clinic visits within a year of the index ED visit for patients with no prior PCP. Results: 1,292 patients were potentially eligible and 853 were enrolled (662 intervention and 191 controls). Groups had similar baseline characteristics. Nearly 75% in both groups had no prior PCP. Using an intention to treat analysis, 50.3% of intervention group patients with no prior PCP achieved successful linkage (95%CI 45.7-54.9%) vs. 36.9% of the control group (95%CI 28.9-45.4%). Conclusion: A point-of-care program offering low-acuity ED patients the opportunity to instead be seen at the hospital's primary care clinic resulted in increased future primary care linkage compared to standard ED referral practices

We have reported results from the formative stage of a community health worker intervention designed to improve diabetes management among Bangladeshi patients in New York City. Trained community health workers conducted focus groups (n = 47) and surveys (n = 169) with Bangladeshi individuals recruited from community locations. Results indicated that participants faced numerous barriers to care, had high rates of limited English proficiency, and had low levels of knowledge about diabetes. Most participants expressed interest in participating in a community health worker intervention.
