Resumo:

The beneficial effects of highly active antiretroviral therapy, increasing survival and the prevention of AIDS defining illness development are well established. However, the annual Portuguese intra-hospital mortality is still higher than expected. It is crucial to understand the hospitalization behavior to better allocate resources. This study aims to estimate the intra-hospital mortality attributable to the variation in hospitals performance, after adjusting for measurable risk factors.
The study population consists of HIV infection discharges in Portuguese National Health Service hospitals from 2005 to 2007 available on the diagnosis related groups database.
We used discharge hospital levels variables to develop a hierarchical model. Results from a frailty survival model of intra-hospital mortality and estimated hazard ratios will be presented.
