Physicians' perceptions of risk adjustment and health policy formation in Minnesota.

A questionnaire was used to assess Minnesota physicians' knowledge of and opinions about risk adjustment, a policy designed to modify payments to health providers based on the relative "sickness" level of the provider's patient population. Additionally, attitudes toward this policy were measured to examine physicians' perceptions of health policy formation in Minnesota. Although familiarity with this policy appears low, respondents support the concept of diagnosis-based risk adjustment. Physicians are divided on whether to further modify risk-adjusted rates with a conversion factor; their written comments suggest a mistrust of the policymaking process. Physicians most often listed the Minnesota Medical Association as a primary source for health policy information, while few respondents reported any communication with state legislators in health policy matters. Respondents perceive an imbalance in the influence wielded by various entities in health policy formation. Only 5% believe individual physicians have significant influence in policymaking. Increased communication between physicians and their legislators may be one way for physicians to gain such influence.
