Abstract 226: Integration of Traditional and Alternate Chronic Care Models within a Primary Care Setting for Diabetes Management and Cardiovascular Disease Prevention

Abstract

Background: Several chronic care models (CCMs) for diabetes management and cardiovascular disease prevention have been implemented, but outcomes have been marginal. Traditionally, CCMs have been offered within the trusted primary care practice environment, but self-management support is episodic, cost ineffective and difficult to scale. Alternate CCMs that offer self-management support mostly through telephone coaching or virtual (web/mobile platforms) interventions, enable easy access, scalability and cost effectiveness, yet are impaired by the limits of isolated self-management support when provided outside the context of the trusted, therapeutic relationship of a primary care practice. We hypothesize that an integrated model taking advantage of positive aspects of traditional and alternate CCMs will lead to positive behavioral change (empowerment), sustained patient participation and better outcomes. Methods: To test this hypothesis, we implemented the Empowerment and Participatory Care Model (EPCM) in a study center in Chennai, India by integrating face-to-face support with customized telephone, Internet and mobile phone enabled interventions within a primary care setting. Patients who participated in the traditional CCM formed the control group. Results: In the participents in traditional CCM (n=422), there was an average reduction of 0.57% in HbA1c, 16 mg/dl in fasting blood sugar, 30 mg/dl in post prandial blood sugar and 16 mg/dl of LDL at the end of year-one. In comparison, among the patients (66% men; mean age 52 yrs) who participated in the EPCM and had completed one-year in the program (n=112) there was average reduction of 1.6% in HbA1c, 57 mg/dl in fasting blood sugar, 80 mg/dl in post prandial blood sugar and 18 mg/dl of LDL (p<0.01). Figure 1 shows the difference in percent reduction of the various biochemical parameters between the EPCM and the control group. The total cost of care (other than medication) per patient per year in the EPCM, after taking into consideration purchasing power parity between USA and India, was 900 USD. Conclusion: The persons with diabetes who participated in the EPCM had better quality of metabolic control, but long-term follow up is required to assess overall reduction in the risk of cardiovascular complications and cost effectiveness.
