OBJECTIVE-Post-emergency department (ED) triage of older trauma patients continues to be challenging as morbidity and mortality for any given level of injury severity tend to increase with age. The Comorbidity-Polypharmacy Score (CPS) combines the number of pre-injury medications with the number of comorbidities to estimate the severity of co-morbid conditions. This retrospective study examines the relationship between CPS and triage accuracy for older (≥45 years) patients admitted for traumatic injury.
METHODS-Patients≥ 45 years old presenting to level 1 trauma center from 2005 to 2008 were included. Basic data included patient demographics, injury severity score (ISS), morbidity/ mortality, and functional outcome measures. CPS was calculated by adding total numbers of comorbid conditions and pre-injury medications. Patients were divided into 3 triage groups: undertriage, appropriate triage, and over-triage. Under-triage criteria included initial admission to the floor or step-down unit followed by an unplanned transfer to ICU within 24 hours of admission. Over-triage was defined as initial ICU admission for <1 day without stated need for ICU level of care (i.e., lack of evidence for tracheal intubation/mechanical ventilation, injuryrelated hemorrhage, or other traditional ICU indications such as intracranial bleeding). All other patients were presumed to be correctly triaged. The three triage groups were then analyzed looking for contributors to mis-triage. RESULTS-Charts for 711 patients were evaluated (mean age 63.5, 55.7% male, mean ISS 9.02). Of those, 11 (1.55%) met criteria for "under-triage" and 14 (1.97%) were "over-triaged". The remaining 686 patients had no evidence of mis-triage. The three groups were similar in terms © 2012 Elsevier Inc. All rights reserved.

The groups were significantly different with respect to CPS, with undertriage CPS scores (14.9±6.80) being nearly three times higher than the overtriage CPS scores (5.14±3.48). There were more similarities between appropriate and overtriage groups, with the undertriage group being characterized by greater number of complications, and lower functional outcomes at discharge (all, p<0.05). The undertriage group had significantly higher mortality (27%) than the appropriate and over-triage groups (6% and 0%, respectively).CONCLUSION-In the era of medication reconciliation, the CPS is easy to obtain and calculate in patients who are not...
