Abstract

Background Older age is associated with high rates of morbidity and mortality after injury. Statewide studies suggest significantly injured patients aged ≥55 y are commonly undertriaged to lower level trauma centers (TCs) or nontrauma centers (NTCs). This study determines whether undertriage is a national phenomenon. Materials and methods Using the 2011 Nationwide Emergency Department Sample, significantly injured patients aged ≥55 y were identified by diagnosis and new injury severity score (NISS) ≥9. Undertriage was defined as definitive care anywhere other than level I or II TCs. Weighted descriptive analysis compared characteristics of patients by triage status. Multivariable logistic regression determined predictors of undertriage, controlling for hospital characteristics, injury severity, and comorbidities. Results Of 4,152,541 emergency department (ED) visits meeting inclusion criteria, 74.0% were treated at lower level TCs or NTCs. Patients at level I and II TCs more commonly had NISS ≥9 (22.2% versus 12.3%, P < 0.001), but among all patients with NISS ≥9, 61.3% were undertriaged to a lower level TC or a NTC. On multivariable logistic regression, factors independently associated with higher odds of being undertriaged were increasing age, female gender, and fall-related injuries. A subgroup analysis examined urban and suburban areas only where access to a TC is more likely and found that 55.8% of patients' age were undertriaged. Conclusions There is substantial undertriage of patients aged ≥55 y nationwide. Over half of significantly injured older patients are not treated at level I or II TCs. The impact of undertriage should be determined to ensure older patients receive trauma care at the optimal site.
