Table 3 Factors associated with potential under-triage: mixed effects regression modelling results
Model 1: Odds of potential under-triage, where secondary triage > = care within 24 h selected, and patient subsequently assessed as requiring immediate or very urgent emergency care in ED | Model 2: Odds of potential under-triage, where secondary triage > = care within 24 h selected in patients subsequently admitted for inpatient care | ||||||
