Abstract

Abstract : BACKGROUND: Rib fractures in the geriatric trauma population are associated with significant morbidity and mortality. The outcomes of surgical stabilization of rib fractures (SSRF) have not been well defined in this population. METHODS: Data from the 2016 to 2017 Trauma Quality Improvement Program database were analyzed. Patients older than 65 years admitted with isolated chest wall injury and multiple rib fractures were abstracted from the database. Multivariate propensity score matching was utilized to stratify patients that underwent rib fixation versus nonoperative management. In the matched cohort, we assessed outcomes including mortality, intensive care unit (ICU) and hospital lengths of stay (LOS), tracheostomy rates, and ventilator-associated pneumonia (VAP) rates. We performed a secondary analysis of patients receiving early (<72 hours) versus late SSRF. RESULTS: Of the 44, 450 patients included in the study analysis, 758 (1.7%) underwent SSRF. Patients undergoing SSRF were younger, had a higher prevalence of flail chest, higher rates of emergency room intubation, higher Injury Severity Score, and increased ICU admission rates. The 1:1 propensity score match resulted in 758 patients in each group. The in-hospital mortality rate was significantly lower in patients that underwent SSRF (4.2% vs. 7.3%, p = 0.01). However, the fixation group also had higher rates of tracheostomy during admission (11.2% vs. 4.6%, p < 0.001) and VAP (3.0% vs. 1.6%, p = 0.007). In a secondary matched analysis of 326 pairs of patients undergoing SSRF, we found that early fixation was associated with decreased rates of VAP (1.5% vs. 4.6%, p = 0.01), fewer ventilator days (4 days vs. 7 days, p = 0.003), shorter ICU LOS (6 days vs. 9 days, p = 0.001), and shorter hospital LOS (10 days vs. 15 days, p < 0.001). CONCLUSION: This study demonstrates a mortality benefit in geriatric trauma patients undergoing SSRF. Early SSRF was observed to be associated with decreased rates of VAP, decreased ICU LOS, and decreased hospital LOS. Early SSRF may be associated with improved outcomes in the geriatric trauma population with multiple rib fractures. LEVEL OF EVIDENCE: Therapeutic/Care management, level III.
