Objective:
To analyze if the adjusted hospital mortality varies according to source of payment of hospital admissions, legal nature, and financing settlement of hospitals.
Methods:
Cros-ssectional study with information source in administrative databases. Specific hospital admission reasons were selected considering the volume of hospital admissions and the list of quality indicators proposed by the North-American Agency for Healthcare Research and Quality (AHRQ). Were analyzed 852,864 hospital admissions of adults, occurred in 789 hospitals between 2008 and 2010, in Sao Paulo and Rio Grande do Sul, applying multilevel logistic regression.
Results:
At hospital admission level, showed higher chances of death male patients in more advanced age groups, with comorbidity, who used intensive care unit, and had the Brazilian Unified Health System as source of payment. At the level of hospitals, in those located in the mean of the distribution, the adjusted probability of death in hospital admissions financed by plan or private was 5.0%, against 9.0% when reimbursed by the Brazilian Unified Health System. This probability increased in hospital admissions financed by the Brazilian Unified Health System in hospitals to two standard deviations above the mean, reaching 29.0%.
Conclusions:
In addition to structural characteristics of the hospitals and the profile of the patients, interventions aimed at improving care should also consider the coverage of the population by health plans, the network shared between beneficiaries of plans and users of the Brazilian Unified Health System, the standard of care to the various sources of payment by hospitals and, most importantly, how these factors influence the clinical performance.
Objetivo:
Analisar se a mortalidade hospitalar ajustada varia segundo fonte de pagamento das internações, natureza jurídica e arranjo de financiamento dos hospitais.
MéTodos:
Estudo observacional transversal com fonte de informações em bases de dados administrativos. Motivos de internação específicos foram selecionados considerando o volume de internações e a lista de indicadores de qualidade propostos pela agência norte-americana de pesquisa em saúde e qualidade (AHRQ). Foram analisadas 852.864 internações em adultos, ocorridas em 789 hospitais entre 2008 e 2010, em São Paulo e Rio Grande do Sul, aplicando regressão logística multinível.
Resultados:
No nível da internação, apresentaram maiores chances de óbito pacientes do sexo masculino, em faixas etárias mais avançadas, com comorbidade, que utilizaram unidade de terapia intensiva, e tinham o Sistema Único de Saúde como fonte de pagamento. No nível dos hospitais, naqueles situados na média da distribuição, a probabilidade de morte ajustada nas internações financiadas por plano ou particular foi de 5,0%, contra 9,0% quando reembolsadas pelo Sistema Único de Saúde. Essa probabilidade aumentou nas internações financiadas pelo Sistema Único de Saúde em hospitais a dois desvios padrão acima da média, passando para 29,0%.
ConclusõEs:
Além das características estruturais dos hospitais e do perfil dos pacientes, intervenções voltadas para a melhoria do cuidado deveriam considerar também a cobertura da população por planos de saúde, a rede compartilhada entre beneficiários de planos e usuários do Sistema Único de Saúde, o padrão de atendimento às diversas fontes de pagamento pelos hospitais e, fundamentalmente, como esses fatores influenciam o desempenho clínico.
