Predictive accuracy of Apache-II for mortality in Poly Trauma patients.

Abstract

Objectives: The objective of our study was to find diagnostic accuracy of APACHE-II score to predict mortality in poly trauma patients within first 24 hours of hospitalization. Study Design: Cross Sectional study. Setting: Department of Emergency Lahore General Hospital. Period: 25 March, 2016 to 25 September, 2016. Material & Methods: A total of 230 patients who fulfilled inclusion criteria were enrolled in the study from emergency department of Lahore General Hospital, informed consent was taken from all patients or their attendants to take their demographic profile (name, age, gender and contact no) and other necessary clinical data. To calculate APACHE-II score, vital signs, blood / serum profile, GCS, age and prolong health problems were measured on patients’ arrival. Patients were classified as per their APACHE-II score. After calculating APACHE-II score patients were managed according to trauma severity and followed up till 24 hours to note the in- hospital mortality. All the data was recorded on a Performa. Statistical analysis was carried out using SPSS 20. Results: Out of 230 patients, 147 (63.91%) were male and 83(36.09%) were female; mean age was 38.53 ± 11.67 years. Out of 230 cases, in hospital mortality occurred in 84(36.5%) while other 146(63.5%) were alive within 24 hours of admission. According to APACHE-II score, 84(36.5%) cases had > 11.5 score and rests of 146(63.5%) had APACHE-II ≤ 11.5. The sensitivity, specificity, PPV, NPV and diagnostic accuracy of APACHE-II was 89.16%, 93.2%, 88.1%, 93.84% and 91.74% respectively. Conclusion: According to the findings of this study, we found APACHE-II highly accurate for indicating in-hospital mortality. Using APACHE-II in future we can devise an efficient treatment plan for poly trauma patients to reduce the probability of hospital mortality.
