Study Description and Methods

In this study, we wanted to describe how primary care clinicians care for patients with type 2 diabetes. This was a descriptive study of predictors of glycemic control of patients with type 2 diabetes mellitus. Physicians from the Minnesota Academy of Family Physicians Research Network (MAFPRN) and two networks in Texas also participated.

Specific Aims and Objectives

Our specific aims were:

  1. To describe the outcomes of type 2 diabetes achieved by primary care physicians and their patients; and
  2. To identify the major patient, physician, and practice characteristics that are associated with varying levels of glycemic control and health-related quality of life indicators.


This study was conducted from February 2001 through April 2002.

Key Findings and Publications

Only modest numbers of patients achieve established targets of diabetes control. Reengineering primary care practice may be necessary to substantially improve care.
