Key Points

The study aimed to evaluate the effects of a culturally tailored collaborative care model on cardiometabolic outcomes and cost savings for high-risk Asian American adults with type 2 diabetes.
Conducted a retrospective cohort study of patients referred to a collaborative care clinic.
Integrated endocrinology management, diabetes self-management education (DSME), nutrition counseling, and bilingual support.
Compared outcomes over 24 months with pre-referral trajectories and concurrent community-managed patients.
A1c reduced by −0.8% in collaborative care compared to −0.1% in community care (p<0.05).

Abstract

Introduction and Objective: Asian American adults with type 2 diabetes develop cardiometabolic complications at lower BMI thresholds that are inadequately addressed by standard care. Cultural and linguistic barriers compound management challenges. We evaluated whether referral to a culturally tailored collaborative model produced sustained improvement and cost savings. Methods: We conducted a retrospective cohort study of patients referred from a community health center to a collaborative care clinic integrating endocrinology-led management, DSMES, nutrition counseling, and bilingual coordination. Patients were compared with pre-referral trajectories and concurrent community-managed patients. Outcomes included A1c, blood pressure, LDL, and composite ABC attainment over 24 months. Mixed-effects regression adjusted for baseline risk. Program costs were micro-costed; cost avoidance derived from utilization changes. Results: Patients entering collaborative care had higher baseline A1c and complexity. Collaborative care produced greater reductions in A1c (−0. 8% vs −0. 1%), LDL (−16 vs −3 mg/dL), and systolic BP (−7 vs −1 mmHg) vs community care (p0. 05). ABC attainment improved from 18% to 29%, comparable to Joslin adult clinic T2DM patients. Each DSMES visit increased ABC odds by 15% (OR 1. 15, 95% CI 1. 05-1. 26). Greatest benefit occurred in patients with A1c ≥8. 5%, eGFR 55-69, and limited English proficiency; language disparities were attenuated. Annual program cost was 1, 300; cost avoidance 2, 580, yielding net savings of 1, 200 per patient. Conclusion: Culturally tailored collaborative care produced sustained cardiometabolic improvement and net cost savings among high-risk Asian American adults previously deemed difficult to manage. Apparent treatment resistance may reflect care model limitations rather than patient characteristics. These findings support culturally concordant care as clinically sustainable and cost-efficient for equity-focused diabetes delivery. Disclosure A. Adam: None. K. Lau: None. J. Li: None. H.
