Evaluation of pharmacists' services for hospital inpatients

Patient satisfaction with pharmacist-conducted weekly medication-education classes and the underlying factor structure of the evaluation items are described. The pharmacist service consisted of weekly, one-hour classes for headache sufferers in a tertiary headache clinic's hospital unit. One pharmacist taught all of the classes and conducted them in the same manner each week, using the Indian Health Service patient-counseling technique. The classes included both lecture and one-on-one interactions. Any patient admitted to the hospital's headache unit was eligible to participate in the study. Patients were asked to complete a survey at the end of the class, evaluating the service in terms of performance, disconfirmation of expectations, affect, equity, and self-efficacy by rating three statements about each of these on a 7-point scale, where 1 = very strongly disagree and 7 = very strongly agree. Exploratory factor analysis was used to investigate the degree to which these five evaluation areas were distinct constructs. A total of 157 patients attended a medication-education class during the study period. Of these, 153 (97%) provided usable data. Respondents favorably evaluated the pharmacist service, as the means were significantly greater than the scales' midpoint scores (p < 0.001). Factor analysis results suggested that covariation in the data was best described by four factors rather than five: (1) performance, (2) disconfirmation of expectations, (3) equity, and (4) self-efficacy. Inpatients attending pharmacist-conducted weekly medication-education classes favorably evaluated the pharmacist service. Four different conceptualizations of patients' evaluations were identified.
