Sequential Organ Failure Assessment (SOFA) score in predicting morbidity and mortality in community and hospital acquired acute renal failure patient requiring dialysis

Abstract

Background: The Sequential Organ Failure Assessment (SOFA) score is an excellent tool for assessing the extent of organ dysfunction in critically ill patients. This study was planned to compare outcome and organ failure status of community (CAARF) and hospital acquired acute renal failure (HAARF) patients requiring dialysis using SOFA score.Methods: The present prospective observational study was conducted on fifty consecutive acute renal failure patients age more than 18 years of either sex requiring dialysis. Patients who developed ARF after 24 hours of admission were referred as HAARF and patients who had acute renal failure on admission were considered as CAARF. The Sequential Organ Failure Assessment (SOFA) score was used to track a patient's status during the stay in an intensive care unit in both HAARF and CAARF patients.Results: Out of 50 patients, 31(62%) patients had community acquired renal failure and 19 (38%) patients had hospital acquired renal failure. Mean SOFA in HAARF patients was high (8.84±3.13) compare to CAARF patients (6.16± 2.80). The p value calculated was 0.003 which was significant. High SOFA Score (>11) were seen predominantly in HAARF (83.3%) patients compare to CAARF (16.7%), followed by 57.1% of patients in HAARF and 42.9% of patients in CAARF had SOFA score between 9 to11.Conclusions: High SOFA Score were seen predominantly in HAARF patients compare to CAARF and so poor outcome compare to CAARF. So, SOFA score may be used in explaining prognosis and outcome of ARF patients.
