Integrating Lifestyle Therapy for Diabetes Prevention Into Primary Care
|Pre-Diabetes Metabolic Syndrome Type 2 Diabetes||Behavioral: Lifestyle intervention and provider feedback|
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Care Provider)
Primary Purpose: Prevention
|Official Title:||Detecting and Managing Metabolic Syndrome and Pre-Diabetes in General Medicine Clinic (Feasibility)|
- Patients adopt healthy lifestyle behaviors leading to significant weight loss, thus reducing their risk of diabetes and heart disease [ Time Frame: 1.5 years ]
- Providers improve their ability to diagnose and treat metabolic syndrome/pre-diabetes. [ Time Frame: 1.5 years ]
- Improve patient understanding of the metabolic syndrome/pre-diabetes risk parameters and the impact of healthy lifestyle changes on reducing their risk of developing heart disease and diabetes. [ Time Frame: 1.5 years ]
- Create a model multidisciplinary team (physician, nurse, dietitian, health educator) to conduct group visits, lifestyle intervention education and follow-up of patients with metabolic syndrome/pre-diabetes. [ Time Frame: 1.5 years ]
- Develop a system-wide database of patients with metabolic syndrome/pre-diabetes to target for preventive care. [ Time Frame: 1.5 years ]
- Establish physician discussions and documentations encouraging lifestyle changes such as weight loss, healthy dietary changes and exercise. [ Time Frame: 1.5 years ]
- Involve nursing staff in waist circumference measurement along with vital signs. [ Time Frame: 1.5 years ]
- Assess changes in insulin resistance using the HOMA-IR index and in vascular inflammation status using C-Reactive protein in the intervention and control groups. [ Time Frame: 1.5 years ]

Lifestyle modification education and counseling for intervention patients. Diagnosis and treatment education and feedback on performance for providers of intervention patients.
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.
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.
