Can a standardized blunt thoracic trauma score lead to lower length of stay and reduced intensive care unit admission for older patients?

We implemented and evaluated a novel score called the blunt thoracic trauma score (BTTS) for the triage of chest wall injury (CWI) patients to optimize utilization of the intensive care unit (ICU). Patients who sustained rib fractures after a traumatic injury (2014-2020) were identified in our trauma registry. Demographics and clinical characteristics were summarized by cohorts pre- and post-BTTS implementation in 2017 and BTTS > 6 versus BTTS < 6 using median or frequency. Wilcoxon rank-sum test was used to compare continuous variables, and &#x3c7;or Fisher's exact test for categorical variables. Logistic/negative binomial regression models were used to find predictors for ICU admission and length of stay (LOS). Six hundred thirty-three patients were included; 407 pre-BTTS/226 post-BTTS. Pre-BTTShigher median ISS (p < 0.001), more rib fractures (p < 0.001). Post-BTTS older (p < 0.001), more comorbidities (coronary artery disease [p = 0.028], hyperlipidemia [p = 0.004], pulmonary disease [p = 0.038]). Post-BTTS cohort had lower rates of ICU admission (p = 0.008), shorter ICU-LOS (p < 0.001), and Hospital-LOS (p < 0.001). Post-BTTS cohort was associated with shorter Hospital-LOS after adjusting for other factors (p = 0.004). Implementation of a novel BTTS for triage of CWI was associated with decreased ICU admission rates and shorter ICU-LOS and Hospital-LOS. The decreased Hospital-LOS persisted even after controlling for other factors.
