Pharmaceutical intervention and prevention of drug related problems

Abstract

In the present study, we describe the pharmaceutical interventions performed by the pharmacy service of a public orthopaedic hospital at Rio de Janeiro, Brazil. In a retrospective study, we analysed the pharmaceutical interventions performed during a year (from june 2004 to june 2005). The pharmacy service assisted 13.6% of the 5476 patients that were submitted to internation. In 30.4 % of the patients that were directly assisted by the pharmacist was identified the necessity of pharmaceutical interventions, reaching 227 interventions during the period of the study. The physicians were the most requested professionals (71.1%), followed by nurses 16.9%. Eighty four percent of the problems that were detected were related to potential medication errors. Forty nine percent of these errors were prevented by the pharmacists. It was possible to predict some of the potential drug related problems that could be related to these patients as well. Seventy percent of the pharmaceutical interventions were accepted by the professionals. For the interventions related to prescription, sixty percent were accepted. The results suggest that pharmaceutical interventions were effective to prevent drug adverse events, reinforcing the important role of pharmacists in hospital assistance.
