Abstract

Objective: To determine mortality and length of stay (LOS) using PRISM III score in critically ill children.
Methodology: This study included a total of 129 patients who met the inclusion criteria. The study was carried out in the Pediatric Intensive Care Unit (PICU) of the UCHS & Children Hospital Lahore, spanning from December 2023 to May 2024.
Results: The mean age of patients was 7.55 ± 4.20 years, with a mean hospital stay of 5.18 ± 1.30 days. Male patients had a mean age of 8.18 ± 4.38 years, while females had 6.79 ± 3.88 years. PRISM score analysis showed a significant trend in discharge and mortality rates. In the 0-4 PRISM range, 84.7% were discharged, while 15.3% died. For scores of 5-9, 83.0% were discharged, and 17.0% died. In the 10-14 range, 57.1% survived, while 42.9% died. Among scores of 15-19, 40.0% were discharged, and 60.0% died. In the ≥20 range, 16.7% survived, while 83.3% died. Linear regression showed a significant association between PRISM score and length of stay (LOS), with a baseline LOS of 4.716 days. Each 1-unit PRISM increase extended LOS by approximately 5 hours (B = 0.069 days). Conclusion: It was concluded that the PRISM III score has discriminatory power in distinguishing between survival and mortality outcomes. Additionally, it proves to be predictor of the length of stay among survivors.
Key words: Length of stay, Mortality, PRISM III score.
