RÉSUMÉ
Objetivo: Analisar o uso de medicamentos potencialmente inapropriados (MPIs) e o uso de medicamentos usados em terapia de suporte que requerem cautela em idosos com câncer (MTSRCICs), determinando os fatores associados. Visou-se também determinar a concordância entre os critérios explícitos empregados na identificação de MPI. Metodologia: Estudo transversal com indivíduos com mieloma múltiplo (MM), idade ≥ 60 anos em tratamento ambulatorial. Os MPI foram identificados de acordo com os critérios AGS Beers 2019, PRISCUS 2.0 e o Consenso Brasileiro de Medicamentos Potencialmente Inapropriados (CBMPI). Os MTSRCIC foram definidos de acordo com a National Comprehensive Cancer Network. Os fatores associados ao uso de MPI e MTSRCIC foram identificados por regressão logística múltipla. O grau de concordância entre os três critérios explícitos empregados no estudo foi mensurado pelo coeficiente kappa Cohen. Resultados: As frequências de MPI foram 52,29% (AGS Beers 2019), 62,74% (CBMPI), 65,36% (PRISCUS 2.0) e 52,29% (MTSRCICs). As concordâncias entre AGS Beers 2019 com PRISCUS 2,0 e com CBMPI foram altas, enquanto a concordância entre CBMPI e PRISCUS 2.0 foi excelente. No modelo final de regressão logística polifarmácia foi associada positivamente ao uso de MPI por idosos para os três critérios explícitos utilizados, além de associado à utilização de MTSRCICs. Conclusões: A frequência do uso de MPI e de MTSRCIC foi elevada. A concordância em relação ao uso de MPI entre os critérios AGS Beers 2019, CBMPI e PRISCUS 2.0 foi alta ou excelente. A polifarmácia apresentou associação independente e positiva com uso de MPIs e de MTSRCICs por pacientes idosos com MM. (AU)
Objectives: To analyze the use of potentially inappropriate medications (PIMs) and medications used in supportive therapy that require caution in older adults with cancer, in addition to determining associated factors the agreement between criteria sets used to identify PIMs. Methods: This cross-sectional study included individuals with multiple myeloma aged ≥ 60 years who were undergoing outpatient treatment. PIMs were identified according to American Geriatric Society Beers 2019, PRISCUS 2.0, and Brazilian Consensus on Potentially Inappropriate Medicines criteria. Medications of concern were defined according to National Comprehensive Cancer Network criteria. Factors associated with the use of PIMs and medications of concern were identified using multiple logistic regression. The degree of agreement between the 3 criteria sets was measured using Cohen's kappa coefficient. Results: The frequency of PIM use was 52.29% according to American Geriatric Society Beers criteria, 62.74% according to Brazilian Consensus criteria, and 65.36% according to PRISCUS criteria, while 52.29% of the patients were using medications of concern. Agreement between American Geriatric Society Beers, PRISCUS, and Brazilian Consensus criteria was high, while it was excellent between Brazilian Consensus and PRISCUS criteria. In the final logistic regression model, polypharmacy was associated with PIM use according to each criteria set, as well as the use of medications of concern. Conclusions: The frequency of PIMs and medications of concern was high. Agreement about PIM use between the American Geriatric Society Beers, Brazilian Consensus, and PRISCUS criteria was high or excellent. There was an independent association between polypharmacy and the use of PIMs and medications of concern by older patients with multiple myeloma. (AU)
