• Standardized PICU Mortality

    Why this measure is important:

    • This measure uses an established method to calculate predicted mortality.  Predicted mortality is a way to measure how likely a child is to die based upon how sick he or she is.  A number less than 1.0 indicates that mortality is LESS than would have been predicted. A number greater than 1.0 indicates that mortality is GREATER than would have been predicted.

    How we measure:  

    • Standardized PICU Mortality Ratio is measured as the ratio of actual deaths over predicted deaths for PICU patients. The number of predicted deaths is calculated during the first 24 hours of a PICU stay using the Pediatric Risk of Mortality (PRISM II) score. This score takes into account how sick a child is using 14 physiologic variables such as vital signs and results of certain laboratory tests.

    What we are doing to improve:

    • We continually monitor performance on this measure and use it as one way to signal when more detailed analysis and additional follow up may be warranted.
    • No one intervention can be identified as key to improved performance on this measure. Rather, we trace a combination of safety improvement interventions to our positive results and sustained excellent performance on PICU standardized mortality. This includes an intense focus on the reliable implementation of care bundles to prevent infections for: patients with central venous catheters, patients who are on ventilators, and patients who undergo surgical procedures. In addition, we attribute our work on reducing serious safety events, early recognition and mitigation of patient deterioration, safe hand-offs, and multidisciplinary and PICU physician-led rounds as part of the combination of efforts to continually improve and keep patients safe.
