The aim is to determine the associations between managed care controls and patient-rated quality of care from primary physicians. In a prospective cohort study, 17,187 patients were screened in the waiting rooms of 261 primary care physicians in the Seattle metropolitan area (1996-1997) to identify 2,850 English-speaking adult patients with depressive symptoms and/or selected pain problems. Patients completed 6-month follow-ups to rate the quality of care from their primary physicians. The intensity of managed care was measured for each patient's health plan, primary care office, and physician. Regression analyses revealed that patients in more managed plans and offices had lower ratings of the quality of care from their primary physicians. Managed care controls targeting physicians were generally not associated with patient ratings.
