Análise da utilização de medicamentos inapropriados em idosos na Atenção Primária à Saúde

Abstract

Introduction: The inappropriate use of medicines by the elderly often leads to disastrous results. Choosing the appropriate medication for the elderly is a fundamental step in preventing adverse events in this age group. To identify such drugs and avoid their use, lists such as the Beers list and the "Brazilian Consensus on Potentially Inappropriate Medicines (MPI) for the elderly" were proposed. Objective: To verify factors associated with the use of inappropriate medications by the elderly population in the context of Primary Health Care. Methods: Cross-sectional study. The prevalence of elderly people who use and also of medicines considered inappropriate by the Beers Criteria 2019 and the Brazilian Consensus on Medicines 2016 was estimated, independently and considering the clinical condition of the elderly. The association between demographic and clinical factors and the use of inappropriate drugs and the relationship between the two classifications for this purpose were verified. Multivariate logistic regression models were built to define the Odds Ratio (OR). Results: A positive report of diabetes, depression, polypharmacy and self-assessment of health were associated with the use of inappropriate medications regardless of clinical condition. Regarding the Consensus, the report of diabetes was not associated. Considering the clinical condition of the elderly, according to the Beers classifications, diabetes, heart disease, polypharmacy and falls were associated with the use of inappropriate medications. Regarding the Brazilian Consensus, depression and not diabetes were associated, in addition to the other variables. Conclusion: The associations were similar between the two classifications, indicating that both are relevant in the identification of inappropriate drugs and can be used to avoid their use with the elderly, in Primary Care.
