Over the past several years, healthcare has been profoundly altered by the growth of managed care. Because managed care integrates the financing and delivery of healthcare services, it dramatically alters the roles and relationships among providers, payers, and patients. While analysis of this change has focused on whether and how managed care can control costs, an increasingly important concern among healthcare providers and recipients is the impact of managed care on the physician–patient relationship. The literature includes a number of theoretical articles and anecdotal accounts of managed care's impact on the doctor–patient relationship, but little data have been collected and analyzed. We designed a survey for distribution to Wisconsin physicians to analyze the prevalence and types of managed care arrangements in the state, and the impact of these arrangements on physicians and their relationships with patients.
