Verification of the relationship between the sequential organ failure assessment score and the length of intensive care unit and hospital stay in terms of medical resources input.

Abstract

This study aimed to clarify the relationship between the sequential organ failure assessment (SOFA) score and the length of intensive care unit (ICU) and hospital stays and verify whether the SOFA score can indicate the optimal length of ICU stay. Medical resource input was evaluated as the medical treatment score, converted by volume, within 2 days after ICU admission. After classifying emergency patients into surgical and nonsurgical categories, the relationship between medical resources, SOFA score, and ICU and hospital stay lengths was analyzed. Medical resource input was high when the SOFA score was high after ICU admission. A positive correlation was confirmed between the SOFA score and length of ICU stay in surgical and nonsurgical patients. Nonsurgical patients are more likely to be discharged within the diagnosis procedure combination hospital stages I and II if medical resources are high in the initial stages of ICU admission. The SOFA score affects medical resource input and the length of ICU stay. The early input of medical resources after ICU admission reduces the length of hospital stay in the diagnosis procedure combination, suggesting that the SOFA score is a valuable indicator of the optimal length of ICU stay.
