Volume, learning-by-doing, and economies of scale in the Brazilian hospital sector: the case of hip arthroplasty

efeito volume-resultado, mortalidade hospitalar, economias de escalaResumo
Este estudo visa verificar se o resultado de saúde dos pacientes submetidos a Artroplastia de Quadril são melhores à medida que o hospital realiza mais desse procedimento (efeito volume-resultado). As evidências apontaram a existência desse efeito no setor hospitalar brasileiro. Explorando a distribuição geográfica das residências dos pacientes e dos hospitais como fonte de variação exógena para o volume, foi identificado que o efeito é resultado da hipótese de practice-makes-perfect, ocorrendo através de ganhos estáticos de escala. Esse resultado sugere que uma política que visa um volume mínimo por estabelecimento hospitalar pode conduzir a melhores resultados de saúde.
