Validity of PRISM Score in Predicting Mortality in a Tertiary Care Hospital in North India
Journal Title: International Journal of Contemporary Medical Research - Year 2018, Vol 5, Issue 9
Abstract
Introduction: Severity of illness assessments is a critical part of ICU management. Study aimed at validiting the Pediatric Risk of Mortality score (PRISM) score in predicting mortality in a tertiary care Pediatric Intensive Care Unit in North India. Material and Methods: It was a Prospective observational study in a Pediatric Intensive Care Unit of a tertiary care hospital in North India. 411 patients were enrolled in the study. We divided patients into two categories based on PRISM-III 24 score - Patients with PRISM score >8 and those with a score of ≤8. Three hundred twenty-three (323) patients had a PRISM score ≤8, and 38 patients died in this category (11.8% mortality). In contrast, 88 patients had a PRISM score >8, and 32 patients died in this category (36.4% mortality). Results: Prism score >8 was a significant predictor of mortality (chi-square value of 29.615 and a p-value of <0.001). The odds ratio for dying in the presence of prism score >8 was 9.28 (9 times more risk of dying compared to patients with a prism score >8) with a 95% CI of 2.47-7.43. Cox regression analysis showed that PRISM score >8 was an independent predictor of mortality. Conclusion: PRISM score is a significant predictor of mortality.
