Patient satisfaction is a valuable indicator of the quality of medical care. We assessed the impact of type of health insurance on satisfaction with seven aspects of medical care among 593 HIV-infected men without AIDS, drawn from three sites in San Francisco, California and Denver, Colorado. After adjustment for site of medical care, patient age, race, income, education, and CD4 lymphocyte count, there were few differences in satisfaction between men with fee-for-service and those with managed care insurance. Men with fee-for-service insurance were significantly more satisfied with their interpersonal relations with their clinicians (p = 0.01) but less satisfied with their finances (p = 0.0001) than persons with managed care. Uninsured men were significantly less satisfied with several aspects of care than insured persons. There were no significant differences in satisfaction between men with managed care and those with public insurance. HIV-infected persons who have a choice of insurance should carefully weigh their options, recognizing the implicit trade-offs between types of insurance. Those who choose fee-for-service insurance can expect to be more satisfied with interpersonal relations with their medical providers but less satisfied with financial aspects of their plans. Efforts to address the low satisfaction of uninsured persons are needed.
