Health care quality assessment under managed care organizations is usually derived from two sources: (1) consumer satisfaction surveys, and (2) The Health Plan Employer Data Information Set reports. There is little published data regarding physicians' critiques. This study surveyed physicians and office managers as to the quality of healthcare under 10 managed care organizations in the Greater Baton Rouge area. Performance indicators in the physician questionnaire focused on personal satisfaction, perception of patient satisfaction, and mental health coverage. The office managers' checklist included payment and certification issues, telephone time spent gaining certification, level of knowledge among plan enrollees of their benefits, appeal process, and adequacy of reimbursement. Means were calculated for each performance indicator and managed care organizations were ranked. Tukey-Kramer's post-hoc multiple comparisons test was used to confirm rank order validity. Significant differences were found among companies. Significant rank-order agreement by both physicians and office managers was evident. The usefulness of such surveys and performing them annually is discussed.
