Description

OBJECTIVE: To assess the validity of an electronic version of the Pediatric Index of Mortality 2 score. DESIGN: Retrospective observational study. SETTING: Pediatric and cardiac ICUs at a quaternary medical center. PATIENTS: Patients more than 60 days old admitted to the PICU or cardiac ICU between January 1, 2010, and December 31, 2014. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: After adapting the Pediatric Index of Mortality 2 score into a version applicable to retrospective electronic health record data, it was validated in a mixed-ICU cohort. A manually ascertained Pediatric Index of Mortality 2 score was directly compared with the electronically derived electronic version of the Pediatric Index of Mortality 2 score in 100 randomly selected patients with good agreement between score components with nine out of 11 components having an intraclass correlation coefficient or Cohen κ greater than or equal to 0.6. In assessing the electronic version of the Pediatric Index of Mortality 2 score in the entire cohort of 12,582 patient encounters, it had good discrimination with area under the receiver operating curve of 0.89, appropriate calibration with no significant difference between observed and expected deaths, and excellent predictive ability with a Brier score of 0.0135. CONCLUSIONS: The Pediatric Index of Mortality 2 score can be adapted to utilize retrospective electronic health record data with acceptable discrimination, calibration and accuracy a large mixed-ICU cohort.
