Objectives: We compared the commonly used Acute Physiology and Chronic Health Evaluation (APACHE) II score and Sequential Organ Failure Assessment (SOFA) score with the quicker and easier Therapeutic Intervention Scoring System (TISS)-28) to examine mortality in intensive care units (ICUs).
Methods: Patients treated in the ICU at Bakirköy Dr. Sadi Konuk Research and Training Hospital between May 2012 and January 2017 were included in the present study. Patients who made a full recovery and were discharged were defined as group 1, whereas those who died were defined as group 2. TISS-28 scores recorded twice in the first 24 h and APACHE II and SOFA scores recorded at the end of 24 h were evaluated. The groups were compared based on demographic data; duration of nursing (h/day); and TISS-28, APACHE II, and SOFA scores.
Results: Of 2191 patients in this 5-year study, 1405 (64%; group 1) were discharged from the ICU and 786 (36%; group 2) died. There was no significant difference in age between the two groups. The median TISS-28 score was 17 in group 1 and 25 in group 2. The median APACHE II score was 18 in group 1 and 29 in group 2. The median SOFA score was 6 in group 1 and 8 in group 2. All three scores were significantly higher in group 2.
Conclusion: TISS-28 scores correlated with APACHE II and SOFA scores, predicting mortality.
