Clinical Trial Summary

An educational intervention in the General Medicine Clinic aimed at both primary care providers (PCPs) and their patients with metabolic syndrome/pre-diabetes (MetSyn/PDM). Improving PCPs ability to detect and manage MetSyn/PDM, as measured by the increased incorporation of MetSyn/PDM into PCPs care plan, and increasing patients' awareness of healthy lifestyle behaviors results in positive patient health behaviors and outcomes.

Description:

The highest diabetes prevalence in the US is among African Americans (13.3%), American Indians (12.8%), and Mexican Americans (9.5%) with 8.7% of European Americans diagnosed with diabetes. In addition, certain minorities also have much higher rates of diabetes-related complications and death, in some instances by as much as 50% more than the general population, highlighting that the greatest need for preventive measures are amongst ethnic minorities.

The efficacy of lifestyle intervention in reducing the incidence of type 2 diabetes has been established by the Diabetes Prevention Program and other studies. The Cook County Bureau of Health Services, a publicly-funded healthcare system serving a primarily low-income, uninsured, ethnically diverse population in Chicago, IL, currently treats an estimated 40,000 patients annually for type 2 diabetes and estimates that another 85,000 to 100,000 patients are at risk for developing diabetes.

Our primary objective was to test the feasibility of integrating less intensive lifestyle intervention therapy into patient visits with their primary care provider to improve weight loss and decrease the intensity of metabolic syndrome and pre-diabetes risk factors. The site of the study is the General Medicine Clinic, a busy primary care outpatient site treating approximately 12,000 patients/year and 200 patients/day, staffed primarily by medical residents supervised by attending physicians.

Intervention

Behavioral:
• Lifestyle intervention and provider feedback
Patients receive lifestyle education and counseling after each visit with their primary care provider. Lifestyle modification goals are set and progress monitored. Frequency is dependent on frequency of visits with primary care provider which can range from one month to nine months. Primary care providers of the intervention patients receive one education session at the commencement of the study covering the diagnosis and treatment of metabolic syndrome and pre-diabetes. Feedback on provider performance as assessed by provider documentation of diagnosis and treatment recommendations compared to patient outcomes is given every six months.
