BACKGROUND: Length of stay (LOS) and patients’ outcome are two important indicators in intensivecare units (ICUs). The severity of illness influences these variables and could have a predictive valuein clinical settings. The impact of severity of illness on the LOS and outcomes in patients admittedto ICUs was investigated in a selected hospital in Iran in 2019.MATERIALS AND METHODS: This research was a descriptive longitudinal study. Data wereprospectively collected on 150 patients. The sequential organ failure assessment (SOFA) score, LOS,and demographic variables of the patients were recorded. Abbreviated mental test and Barthel indexmeasuring activities of daily living questionnaires were completed at the time of the discharge fromICU and 1 month later to show the patient outcomes. Data analysis was performed using Chi‑squaretest, t‑test, analysis of variance, Pearson’s correlation, and linear and ordinal logistic regression withSPSS software version 16.RESULTS: The mean of LOS was 11.21 ± 10.54 days. 24.7% of the patients were discharged fromICUs with optimal recovery, 49.3% with poor recovery, and 26% died in ICUs. One month afterdischarge, 67.6% of patients had optimal recovery, 24.3% had poor recovery, and 8.1% died. TheSOFA score had a significant relation with LOS and patient outcomes in discharge and 1 month later.All the patients with SOFA score <5 survived, and all the patients with SOFA score more than 12 died.CONCLUSIONS: The severity of illness had a significant relation with LOS and patient outcomes inthe time of the discharge from ICU and 1 month later. It seems that the initial SOFA score of 12 andhigher can be suggested as a cutoff point for poor prognosis in ICU patients.
