[Multiple correspondence analysis in the evaluation of hospital pharmacy services in Brazil]

This study aimed to evaluate associations among variables in hospital pharmacy services. Thirty variables were used from the project Diagnosis of Hospital Pharmacies in Brazil pertaining to the overall description of the hospital, overall characterization of the hospital pharmacy service, and stages in pharmaceutical care. The statistical techniques were multiple correspondence and cluster analysis. Dimension 1 of the multiple correspondence analysis explained 90.6% of variance, differentiating between hospital pharmacy services based on the presence of certain activities, thus suggesting an axis of characterization for the hospital pharmacy services. The results indicate a direct relationship between compliance with the activities and the type of hospital and pharmacists with specialized training. Cluster analysis identified six clusters related to hospital size; greater compliance with the activities was associated with large hospitals and those with a pharmacist (more time dedicated to the hospital pharmacy service and higher level of training). The study concludes that the techniques were able to identify associations and a concise range of variables for a comprehensive evaluation of hospital pharmacy services in Brazil.
