Abstract

Background: Hospital drug therapy has the potential for incidents, thus it is necessary to identify situations that may compromise patient safety.Objective: To investigate potential drug-drug interactions caused by the overlapping of medications planned by nurses in the patients’ prescriptions at a hospital inpatient unit.Methodology: Descriptive, cross-sectional study of documentary analysis with a quantitative approach, of 260 prescriptions for adult patients. Potential drug- interactions were identified using the Drug Interaction Checker (Medscape®).Results: A total of 3066 doses were analyzed, with a concentration of 4 schedules, showing an institutional standardization of schedules. The omission error rate was 5.44%. Drug-drug interactions of moderate severity were more frequent, especially lopinavir/clonazepam and diazepam/tramadol combinations.Conclusion: Omission errors and interactions can be minimized with tools to support clinical decision and reconfiguration of the work process.

Highlights

  • Hospital drug therapy has the potential for incidents, it is necessary to identify situations that may compromise patient safety

  • Quanto às interações medicamentosas com risco moderado, significa que a interação resulta em exacerbação do problema de saúde do doente e/ou requer uma alteração na farmacoterapia (Lima & Godoy, 2017; Drug Interaction Checker, 2019)

  • Relativamente às limitações deste estudo, pode referir-se que, apesar do número expressivo de doses medicamentosas analisadas, os resultados obtidos não permitem generalização por serem obtidos em apenas duas unidades de internamento, podendo ocorrer resultados diferentes em outras realidades
