Mortality outcomes in hospitals with public, private not-for-profit and private for-profit ownership in Chile 2001-2010

Accepted 21 December 2014 Public, private not-for-profit (PNFP) and private for-profit (PFP) hospitals may have different behaviour and performance in different indicators such as health outcomes, cost-efficiency and quality. Chile has a mixed healthcare system both in financing and service delivery. The public National Health Fund (Fondo Nacional de Salud) covers 76% of the population-poorer and with higher health risks-whereas private health insurers cover 16% of the population-richer and with lower health risks. The aim of the study was to analyse the in-patient mortality outcomes by hospital ownership in Chile. Methods: We use hospital discharge data in Chile for the period 2001-10 with a total of 16 205 314 discharges in 20 public, 6 PNFP and 15 PFP hospitals. We analyse in-patient mortality considering all diagnoses and a subsample considering only myocardial infarction and stroke diagnoses. Using a probit regression, we estimate how hospital ownership explains in-patient mortality controlling for other confounding variables like health and socioeconomic status, and hospital characteristics. Results: The discharge condition was reported as death in 3.5% of the public hospitals' discharges, 1.3% in PNFP and 0.7% in PFP. PNFP and PFP hospitals show a lower risk of in-hospital mortality for all diagnoses, myocardial infarction and stroke in comparison with public hospitals. Discussion: The question about which type of hospital ownership performs better in Chile remains open. Policy decisions regarding health service provision requires more evidence explaining differences by ownership. Better controls for health risk and hospital characteristics are suggested to address these differences in hospital performance.
