Mortality analysis as a tool for quality improvement in a general surgery service

The present study aims to propose a method to improve healthcare quality based on systematic analysis of mortality and mortality-related adverse effects. We analyzed all deaths in the surgery service between January, 1997 and December, 2003. There were 10,905 hospital admissions and 194 deaths. The...

Description
Summary:	The present study aims to propose a method to improve healthcare quality based on systematic analysis of mortality and mortality-related adverse effects. We analyzed all deaths in the surgery service between January, 1997 and December, 2003. There were 10,905 hospital admissions and 194 deaths. The mean number of deaths per year was 28 (range 24-36). The mean number of deaths/discharges per year was 1.77 (SD 0.2; range 1.5-2.13). The overall mean age was 80.5 years (SD 9.5; range 47-100). By sex there were 104 women (53.6%) and 90 men (46.6%). During the study period 9,437 patients underwent surgery. We defined the concept of death secondary to a hospital problem (DSHP): this easily objectified concept includes any hospital problem occurring from admission to death associated directly or indirectly with death, or simply precipitating a foreseeable death. We detected 33 DSHP. Of all deaths, 17% were DSHP. In these DSHP, 37 problems were detected (some deaths involved more than one problem). The most frequent types of problem were three nosocomial infections, 19 problems secondary to therapeutic or diagnostic techniques, seven insufficient evaluations or treatment omissions or delays, and eight harmful incidents. No deaths occurred because of organizational or structural problems. The number of DSHP in relation to discharges was 0.3%. We present a system of continuous self-evaluation, in which problems are recognized and a constructive attitude is adopted. The model can be extrapolated to other hospitals but the results must be evaluated in the specific context of each hospital. Nevertheless, the results can be used for monitoring within a single center over a period of years.
