AbstractThe outcome of chronic kidney disease (CKD) patients admitted to the Intensive Care Unit (ICU) is difficult to predict. This study assessed the outcome of CKD patients admitted to the ICU and evaluated prediction of 30-day mortality using the Acute Physiology and Chronic Health Evaluation (APACHE II), Simplified Acute Physiology Score (SAPS II), and Sequential Organ Failure Assessment (SOFA) score. One hundred consecutive CKD patients admitted to the ICU at a tertiary care hospital, Ahmedabad between 2011 and 2013 were included prospectively. Data on demographics, indication for admission, cause of CKD, use of vasoactive drugs and mechanical ventilation (MV), mode of renal replacement therapy (RRT), and 30-day mortality were recorded. The APACHE II, SAPS II, and SOFA scores were calculated based on the admission characteristics. The mean APACHE II, SAPS II, and SOFA scores were 28.22 ± 7.53, 43.04 ± 16.40, and 10.39 ± 5.20, respectively, and area under receiver operating characteristics curve in predicting 30-day mortality were 0.961, 0.994, and 0.950, respectively. The scores were significantly higher in 30-day nonsurvivors as compared to survivors (P = 0.001). During the ICU stay, MV and vasoactive drugs were required in 57% and 67% of the patients, respectively, and the requirement was significantly greater in nonsurvivors as compared to survivors (P = 0.001). About 85% of patients were on intermittent hemodialysis and 15% of patients were on continuous venovenous hemodiafiltration. Sepsis was the main reason for hospital admission, and the mean length of stay in the ICU was 7.74 ± 5.34 days. The study indicates that all three scores (APACHE II, SAPS II, and SOFA) perform equally well and have equal diagnostic utility in predicting 30-day mortality.
