150 patients attending an outpatient clinic at the University of Oklahoma Hospital over a 5-week period were asked whether the clinic care they were receiving was better than, as good as, or worse than the care they had received from local physicians. The patients were drawn from the general medicine, cardiology, and oncology-hematology units and tended to be elderly and chronically ill. Most of the patients viewed favorably the care they received in the medical outpatient clinics. 65% reported they had experienced pain or discomfort in the week prior to their visit, but there was no association between these factors and degree of satisfaction with clinic care. Patients averaged about 30 minutes with the physician, and 80% felt the doctor adequately explained their medical condition to them. Patients who rated the clinic care as being worse than the care of private practitioners felt that their condition was not adequately explained. When asked to define a "good doctor," patient responses were "interest in the patient," "skilled and thorough," and "explains things to you." Characteristics identified as being most important in a "good clinic" were; good doctors, well-trained staff, and information from doctors. Of all the factors examined, the one associated most directly with patient satisfaction was personal interest on the part of the physician in the patients.
