Analysis of deaths among critical patients: comparison of estimated mortality by saps-3 and observed mortality

Abstract

Objective: to compare the mortality estimated by the SAPS-3 with the observed mortality among critically ill patients admitted to an Intensive Care Unit and to identify the factors associated with death. Methods: longitudinal study carried out with secondary data from 400 critically ill patients. Estimated and observed mortality and the factors associated with death were compared. Results: there was a predominance of elderly patients (mean age 65.5 years) male (50.5%), with hospitalization financed by the Unified Health System (78.0%). The patients with the highest severity score and the highest estimated mortality were those who died (p<0.001). Death was associated with hospitalizations for infectious and parasitic diseases (p<0.001), while most patients hospitalized for external causes were discharged (p<0.001). Conclusion: the patients with the highest severity by SAPS-3 were those who died, with a predominant negative outcome among those hospitalized for infectious and parasitic diseases.
