Assessment of patient satisfaction with pharmaceutical services in a Nigerian teaching hospital

Objective To assess patients' satisfaction with pharmaceutical services using an“ideal referent” model, and to further explore the validity of an existing patient satisfaction instrument. Method A cross-sectional survey was conducted with a sample of 500 outpatients recruited consecutively at the University of Benin teaching hospital, Nigeria. A self-completion questionnaire that employed a Likert-type scale was used. Data were used to calculate scores on a scale that ranged from 20 to 100, with an assumed midpoint of 60. Descriptive statistics on the sample characteristics and questionnaire items were computed including means, standard deviations and frequency distributions. Varimax rotation with Kaiser normalisation was employed in principal factor analysis. Student's t-test and one-way ANOVA were used for inferential statistics. Key findings The instrument reliability was determined to be 0.9641 and was comparable to the reference study. Nearly half of the patients (46%) rated the amount of time the pharmacist offered to spend with them as poor. About one-third rated promptness of prescription service as poor. Only 49% felt satisfied with the pharmaceutical services. Overall, pharmacy services received a satisfaction rating of 56.04±24.49, below the midpoint. Perceived satisfaction was significantly higher in “friendly explanation” than in “managing therapy” (t=3.916; P<0.0001). Conclusion The study provides evidence that patients experience low satisfaction with current pharmaceutical services at the study hospital. The sociodemographic characteristics of patients were not associated with their level of satisfaction. We further confirm the validity of the patient satisfaction questionnaire in a Nigerian practice setting.
