Cleveland Clinic Children's Outcomes
Pediatric Critical Care
Standardized Mortality Ratio, Unplanned Readmissions, and Length of Stay Ratio
2014 - 2018
The standardized mortality ratio (SMR) is the ratio of actual deaths to predicted deaths. The number of predicted deaths is calculated using the Pediatric Risk of Mortality III (PRISM III) score or the Pediatric Index of Mortality 2 (PIM 2) score — physiology-based mortality risk tools widely used to predict the intensive care outcomes of children. An SMR of 1 indicates that observed mortality is equal to predicted mortality. An SMR > 1 suggests that more patients died than predicted using PRISM III or PIM 2, whereas an SMR < 1 indicates that fewer patients than predicted died.
