PHARMACIST INTERVENTIONS IN AN PUBLIC EMERGENCY HOSPITAL SERVICE OF PORTO ALEGRE

Abstract

Objective: To analyze the records of pharmaceutical interventions of a public emergency hospital. Methods: This is a descriptive and retrospective study based on a database of records of pharmaceutical interventions performed in 2022 by the Clinical Pharmacy Service of a public emergency hospital. The interventions were quantified and classified according to the service's standards. New categorizations of pharmaceutical interventions were performed using the classification for drug-related problems of the Pharmaceutical Care Network Europe in version 9.1. Results: During 2022, 414 pharmaceutical interventions related to 337 patients were recorded. Regarding the location, the interventions were performed on patients admitted to the clinical inpatient unit (35%), intensive care unit (33%), emergency room (27%), and surgical recovery room (5%). According to the service's own classification, reconciliation of health information (36%) and dose or frequency adjustment (33%) were the most frequent pharmaceutical interventions. Using the PCNE system to classify pharmaceutical interventions, the main problems identified were: effectiveness (85.99%) and safety of treatment (7%); the main causes were: dose selection (36.23%) and patient transfer (36.71%); and the main type of intervention: related to the prescriber (92.51%). Conclusions: The study demonstrated the importance of pharmaceutical interventions in clinical and intensive care units. In the classification of the service, dose adjustment is classified as an intervention, while in the PCNE it is the cause of the problem identified in the evaluation of the prescription. The use of the PCNE has the advantage of being able to compare pharmaceutical interventions between different services; in addition, the logic of the registration process is initiated by the real or potential problem of the prescription evaluated.
