Abstract

This study was conducted to investigate whether outcomes of medical emergency team (MET) activations differ by time of day of hospitalized pediatric patients. This is a retrospective cohort study conduct at a tertiary pediatric hospital. Data were extracted from the charts of 846 patients (with one or more MET activations) over a 5-year period. Also can remove hospital names and affiliated institution from the body of the text as readers can find this information in the author list. Patients included children <18 years, admitted to a pediatric ward, who experienced a MET activation between January 1, 2016 and December 31, 2020. We excluded patients reviewed by the MET during a routine follow-up, planned pediatric intensive care unit (PICU) admissions from the ward, and MET activation in out-patient settings, post-anesthesia care unit, and neonatal intensive care unit. There was no intervention. A total of 1,230 MET encounters were included as part of the final analysis. Daytime (08:00–15:59) MET activation was associated with increased PICU admission (25.3%, p = 0.04). There was some evidence of a higher proportion of critical deterioration events (CDEs) during daytime MET activation; however, this did not reach statistical significance (24%, p = 0.09). The highest MET dosage occurred during the evening hours, 16:00 to 23:59 (15/1,000 admissions), and it was lowest overnight, 00:00 to 07:59 (8.8/1,000 admissions, p < 0.001). This period of lowest MET dosage immediately preceded the highest likelihood of PICU admission (08:00, 37.5%) and CDE (09:00, 30.2%). Following the period of lowest MET activity overnight, MET activations during early daytime hours were associated with the highest likelihood of unplanned PICU admission and CDEs. This work identifies potential high-risk periods for undetected critical deterioration and targets for future quality improvement.
