Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The proposed study will inform efforts to prevent diabetes and promote weight loss in a high-risk population and generate a reproducible, scalable, and sustainable model for use with other insurer groups and clinical settings that work in immigrant populations with a high burden of chronic disease.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study "Integrated Community-Clinical Linkage Model to Promote Weight Loss among South Asians with Pre-Diabetes" aims to test the effectiveness and assess the implementation process of an integrated intervention to support weight loss for South Asian patients at-risk for type-2 diabetes mellitus (T2DM) in primary care settings. The integrated intervention involves:

1. An electronic health record (EHR) intervention for primary care providers (PCPs) utilizing embedded alerts to increase screening and identification of South Asian patients at-risk for T2DM with BMI \>23 kg/m2 and registries to track outcomes: and
2. Registry-driven community health worker (CHW)-led health coaching for patients. Using a stepped-wedge design, we will implement the study in 25 New York City PCP sites enrolling 2,840 South Asian patients at- risk for T2DM.
3. Provider Surveys (n=40) to capture data on satisfaction with workflow before and after intervention, information sources for EHR-CHW initiatives before and after intervention, acceptability of and satisfaction with the integrated EHR-CHW intervention, and barriers and facilitators of point-of-care use of the tools.
4. Key Informant Interviews (n=35) with physician champions at each site and/or administrator of each site, Health first representatives, and CHWs. At baseline, the interviews will be incorporated into the workflow analysis to assess current satisfaction and usage of EHR and health coaching. At follow-up, the interviews will assess barriers and facilitators to the implementation and adoption process of the integrated EHR-CHW intervention, fidelity to the interventions, and to solicit recommendations for the replication and scalability of the intervention to other sites and insurer organizations.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Alert + CHW-Led Coaching

Participants will receive an alert and registry-driven CHW-led coaching during either the first or second round.

Group Type EXPERIMENTAL

CHW-Led Health Coaching

Intervention Type BEHAVIORAL

The CHW intervention includes a protocol that consists of 5 monthly 90-minute group health education sessions, providing the tools and strategies to prevent diabetes.

EHR Alerts

Intervention Type OTHER

Primary care providers (PCP) treating patients in the intervention group will receive embedded EHR alerts to increase screening and identification of South Asian patients at-risk for T2DM with BMI \>23 kg/m2 and registries to track outcomes.

Usual Care - Wait-List Control

All participants waitlisted during the first round will be randomized to the control group. Control group participants will be offered the full CHW group education sessions during the second round. The control participants will receive usual care during the first round.
