Use of fall risk-increasing drugs in older adults with multiple myeloma: A cross-sectional study.

OBJECTIVE: To investigate the use of fall risk-increasing drugs (FRIDs) and associated factors and to assess the use of medicines that induce neuropathy in older adults with multiple myeloma (MM). METHODS: Cross-sectional study with older adults with MM treated at the outpatient oncology and hematology services in a southeastern Brazilian capital. FRIDs were classified according to the Screening Tool of Older Persons Prescription in older adults with high fall risk (STOPPFall). The high risk of falling was defined using the Medication Fall Risk Score scale, and the medicines that induce neuropathy were identified according to Vilholm et al. (2014) and Jones et al. (2019). Univariate and multivariate analyses were performed to verify the association between variables. RESULTS: Approximately 54.2% of the 153 older adults included in the study were female, and the median age was 70.9 years (IQR = 13; min = 60 and max:92). Around 71.3% used FRIDs, and diuretics (25.6%), antidepressants (20.5%), and opioids (19.9%) were the most used. A total of 32.7% had a high risk of falling. Polypharmacy was associated with a higher risk of using FRIDs. Statins used concomitantly with immunomodulators or bortezomib were the most used neuropathyinducing drugs, increasing fourfold the likelihood of reporting peripheral neuropathy. CONCLUSION: The frequency of use of FRIDs is high in older adults with MM and is positively associated with polypharmacy.

Validation of an Instrument for Measuring Adherence to Treatment With Immunomodulators in Patients With Multiple Myeloma.

Background: Validate the Treatment Adherence Measure (TAM) instrument in outpatients with MM concerning construct validity, reliability and the ceiling and floor effects. Methods: This cross-sectional study included patients diagnosed with MM previously treated with an immunomodulator for at least one month, aged 18 or over, and followed-up in the investigated outpatient clinics. Adherence to immunomodulators was measured by TAM. The TAM's reliability was assessed using Cronbach's alpha; The association between adherence and health-related quality of life was investigated to analyze the divergent and convergent construct, measured by the Quality of Life Questionnaire core (QLQ-C30) and the Quality of Life Questionnaire Multiple Myeloma module (QLQ-MY20). The presence of a ceiling or floor effect in the TAM was also analyzed. Results: Eighty-four patients were included in the study, achieving 97.6% adherence. Cronbach's alpha was 0.41, and the hypothesis of convergent construct validity was confirmed, with statistical significance, in contrast to the hypothesis of divergent construct validity. The presence of the ceiling effect in TAM suggested that this instrument does not allow changes to be detected in individuals concerning adherence to IMiDs. Conclusion: TAM instrument did not show satisfactory validity and reliability to measure MM's adherence. MM patients treated at oncohematological outpatient clinics in a metropolitan region of southeastern Brazil showed high adherence to IMiDs.

Suitability of new drugs registered in Brazil from 2003 to 2013 for pediatric age groups.

OBJECTIVE: To analyze suitability of new drugs registered in Brazil from 2003 to 2013 for pediatric age groups. METHODS: A descriptive study of drugs with pediatric indication included in a retrospective cohort of new drugs registered in Brazil. The evaluation of drug suitability for the pediatric age group was performed using the following criteria: suitability of dosage form and capacity to deliver the recommended dose. The drugs were considered adequate for the pediatric age groups when they met both criteria. The statistical analysis included calculation of frequencies and proportions. RESULTS: Suitability due to the drug capacity to deliver the recommended dose was greater than 80% across all age groups. Regarding suitability of the dosage form, we identified that the older the age group, the greater suitability for pediatric use. Concerning the drugs presented in solid dosage form, we showed that half were classified as inadequate for one or more pediatric age groups to whom they were indicated. The adequacy of drugs to the pediatric age group was 64.3% for preschool children, 66.7% for full-term newborns, 66.7% for premature newborns, and over 70% for other age groups. CONCLUSION: Drugs for children aged under 6 years were less often adequate, considering the dosage form and capacity to provide the recommended dose. The availability and proportional suitability of medicines for pediatric use are greater for older age groups, according to age groups the drug is registered for.

RESUMO Objetivo Analisar a adequação às faixas etárias pediátricas dos medicamentos novos registrados no Brasil no período de 2003 a 2013. Métodos Estudo descritivo dos medicamentos com indicação pediátrica incluídos em uma coorte retrospectiva de medicamentos novos registrados no Brasil. A avaliação da adequação do medicamento à faixa etária pediátrica foi realizada empregando os seguintes critérios: adequação da forma farmacêutica e capacidade de fornecer a dose recomendada. Os medicamentos foram considerados adequados às faixas etárias pediátricas quando preencheram os dois critérios. A análise estatística compreendeu cálculo de frequências e proporções. Resultados A adequação devido à capacidade do medicamento fornecer a dose recomendada foi superior a 80% em todas as faixas etárias. Em relação à adequação da forma farmacêutica, identificou-se que quanto maior a faixa etária, maior a proporção de adequação para uso pediátrico. Em relação aos medicamentos que se apresentavam em formas farmacêuticas sólidas, evidenciou-se que metade foi classificada como inadequada para uma ou mais faixas etárias pediátricas para as quais estavam indicados. A adequação dos medicamentos à faixa etária pediátrica foi 64,3% para pré-escolares, 66,7% para recém-nascidos a termo, 66,7% para recém-nascidos prematuros e superior a 70% para as demais faixas etárias. Conclusão Os medicamentos destinados às crianças menores de 6 anos apresentaram menor frequência de adequação, considerando a forma farmacêutica e a capacidade de fornecer a dose recomendada. A disponibilidade e a proporção de adequação dos medicamentos para uso pediátrico aumentam com a elevação da faixa etária para a qual o medicamento é registrado.
