Measuring outcomes of care in an ambulatory primary care population. A pilot study.

This study developed a practical method for determining the functional outcome status of patients in an ambulatory setting. Health status of 1,840 primary care patients in an ambulatory setting. Health status of 1,840 primary care patients was compared at three points in time: patient's usual status, status at the initial visit, and status at time of telephone follow-up. Follow-up status was also compared with the physician's expectation, which was estimated at the time of the initial visit. Of the patients, 62% showed improvement, 31% remained at the same level, and 7% deteriorated from the time of their initial clinic visit. Physicians tended to overestimate either the speed or degree with which patients return to their usual functional status; 32% of the patients studied reported themselves as being less well than usual at the time of follow-up.
