Abstract

APACHE IV could predict mortality rate and length of stay for ICU patients. At this study, we compared predicted mortality rate for patients who were admitted in the intensive care unit of Babol Ayatollah Rohani Hospital based on APACHE IV. Materials & Methods: In this cross-sectional study which was carried out from April 2012 to April 2013, all the patients who were admitted in the medical intensive care unit of Ayatollah Rohani Hospital were evaluated. Exclusion criteria included all the patients less than 16 years of old, pregnant, after cardiopulmonary resuscitation, patients who died within 24 hours in the ICU. The method of data collection was based on questionnaires APACHE IV. All data were collected in the first 24 hours of ICU admission. The observed mortality rate and length of stay were compared with predicted mortality and the predicted length of stay. Results: The study was conducted on 106 patients admitted to ICU with 54 patients (50.9%) males and 52 (49.1%) were female. The mean age of patients was 64.43±18.62, and the mean length of stay was 19.3±17.54. During this study, 56 patients (53.8%) were transferred from the ICU, and 50 patients (47.2%) died. Mortality rate predicted by APACHE IV is %34.58±24.76, and the length of stay predicted by APACHE IV is 4.76±1.59 days. The actual and predicted mortality rate were statistically associated (P <0/001), and a weak correlation was found between predicted and actual length of stay (P = 0.002, and correlation = 0.298). Conclusion: The actual mortality rate was similar to the mortality predicted by APACHE IV. The length of hospital stay was greater than the expected time. The results indicated an acceptable quality of health care provided in the intensive care unit of Ayatollah Rohani Hospital.
