Background and Aims Different scoring systems are used in predicting the health outcome and mortality rate of ICU patients. APACHE-II score has been found to have a discriminative value in predicting the mortality rate. There are some limitations to the use of this score such as the patients with multiple comorbid conditions and the physiological variables are all dynamic, that may alter the predicted mortality rate. This study is done in Surgical ICU (SICU) of DHMC, Lahore to see the diagnostic value of APACHE-II in predicting mortality rate and length of ICU stay.

Study Design: Prospective Cross-sectional Study Study Settings: Surgical ICU, Doctors Hospital and Medical Centre, Lahore, Pakistan Study Period: One year period from 1st December 2022 to 30th November 2023. Sampling Technique: Non-probability consecutive sampling All captured data were recorded and analysed in an Excel (Microsoft Corporation, USA) spreadsheet. Descriptive statistics were used. Continuous variable were compared using unpaired ‘t’ test / Mann-Whitney test between groups and paired ‘t’ test within groups at various follow-ups.
