Insights
Four clusters of medical emergency team (MET) triggers were identified in pediatric patients. Specific trigger combinations, like low oxygen and altered mental status, were linked to worse outcomes, guiding better emergency care.
Area of Science:
- Pediatric critical care medicine
- Clinical informatics
- Healthcare quality improvement
Background:
- Medical emergency teams (METs) are crucial for managing clinical deterioration in acute care.
- Understanding patterns of MET activation triggers and their impact on patient outcomes is limited.
- Pediatric MET activation patterns require further investigation to optimize patient care.
Purpose of the Study:
- To identify and describe clusters of triggers activating pediatric METs.
- To examine the association between these trigger clusters and patient outcomes.
- To inform clinical decision-making and predictive modeling for pediatric emergencies.
Main Methods:
- Utilized data from the Get With The Guidelines®-Resuscitation registry (2015-2019) for 4289 pediatric MET events.
- Applied cluster analysis to group MET activation triggers into distinct clusters.
- Employed statistical methods (Pearson χ2, ANOVA, hierarchical logistic regression) to compare patient characteristics and assess outcome associations.
Main Results:
- Identified four distinct MET trigger clusters based on presenting signs and symptoms.
- Cluster 1 (low oxygen saturation, altered mental status) and Cluster 3 (new breathing difficulty, staff concern) were associated with increased critical care transfer.
- Cluster 1 was also linked to a higher likelihood of acute respiratory compromise requiring assisted ventilation.
Conclusions:
- Four unique pediatric MET trigger clusters demonstrate varying associations with patient outcomes.
- MET trigger clusters can enhance bedside triage and clinical emergency management.
- These findings can contribute to developing more precise predictive models for identifying clinical deterioration.
Objectives:
Medical emergency teams (METs) are activated in response to signs and symptoms, or triggers, of clinical deterioration in acute care settings. However, the patterns in which triggers manifest and impact outcomes are poorly understood. We identified and described the patterns in which multiple triggers cluster to activate pediatric METs and examined the associations between these clusters and outcomes.
Methods:
Pediatric MET events from January 2015 to December 2019 in the Get With The Guidelines®-Resuscitation national registry focused on METs (N = 4289) were grouped into MET trigger clusters using cluster analyses based on triggers used to activate the MET. Differences in patient characteristics across MET trigger clusters were compared using Pearson χ2 and analysis of variance (ANOVA) tests. Hierarchical logistic regressions tested associations between trigger clusters and outcomes.
Results:
A total of 4 MET trigger clusters were identified. The triggers that predominantly defined each cluster were as follows: Cluster 1, decreased oxygen saturation and mental status changes; Cluster 2, tachypnea, tachycardia, and staff concern; Cluster 3, new onset difficulty in breathing and staff concern; and Cluster 4, the reference cluster, tachypnea, new onset difficulty in breathing, and decreased oxygen saturation. Patients in Cluster 1 were more likely to experience acute respiratory compromise (need for emergent assisted ventilation), and patients in Clusters 1 and 3 were more likely to be transferred to critical care.
Conclusions:
A total of 4 MET trigger clusters were identified and have varying associations with outcomes. MET trigger clusters could guide bedside care and triage in clinical emergencies and help develop more accurate predictive models for detecting clinical deterioration.
