4 MATERIAIS E MÉTODOS
7.1 Limitações e pontos fortes do estudo
O estudo apresentou limitações inerentes a estudos transversais com impossibilidade de avaliar causalidade entre as variáveis. A diferença temporal entre a ocorrência de quedas e o uso do SUS pode ter levado à diminuição vertiginosa do número de indivíduos que seriam utilizados para calcular os custos e, com isso, perda de dados valiosos. Além disso, fatores de confusão como sono de má qualidade, comorbidades e uso regular de medicamentos não puderam ser descartados.
Os pontos fortes do estudo incluem o caráter pouco aprofundado do tema de associação entre o cochilo e ocorrência de quedas em adultos e idosos, já que a grande maioria dos estudos versa apenas sobre os idosos. Estudos de estimativa de custos utilizando PROs são pouco realizados no país e podem ser base para tomadas de decisão na definição de tecnologias de saúde.
