Assessment of a Situation Awareness Quality Improvement Intervention to Reduce Cardiac Arrests in the PICU.

Abstract

To use improved situation awareness to decrease cardiopulmonary resuscitation events by 25% over 18 months and demonstrate process and outcome sustainability. Structured quality improvement initiative. Single-center, 35-bed quaternary-care PICU. All patients admitted to the PICU from February 1, 2017, to December 31, 2020. Interventions targeted situation awareness and included bid safety huddles, bedside mitigation signs and huddles, smaller pod-based huddles, and an automated clinical decision support tool to identify high-risk patients. The primary outcome metric, cardiopulmonary resuscitation event rate per 1,000 patient-days, decreased from a baseline of 3.1-1.5 cardiopulmonary resuscitation events per 1,000 patient-days or by 52%. The secondary outcome metric, mortality rate, decreased from a baseline of 6.6 deaths per 1,000 patient-days to 3.6 deaths per 1,000 patient-days. Process metrics included percent of clinical deterioration events predicted, which increased from 40% to 67%, and percent of high-risk patients with shared situation awareness, which increased from 43% to 71%. Balancing metrics included time spent in daily safety huddle, median 0.4 minutes per patient (interquartile range, 0.3-0.5), and a number needed to alert of 16 (95% CI, 14-25). Neither unit acuity as measured by Pediatric Risk of Mortality III scores nor the percent of deaths in patients with do-not-attempt resuscitation orders or electing withdrawal of life-sustaining technologies changed over time. Interprofessional teams using shared situation awareness may reduce cardiopulmonary resuscitation events and, thereby, improve outcomes.
