IntroductionPrior studies have shown that the surgical stabilization of rib fractures (SSRF) for patients with multiple rib fractures is associated with improved outcomes by restoring chest wall integrity and decreasing time to return to prior functional status. It is unclear if patients with pulmonary comorbidities (PCM) would benefit from this procedure.ObjectiveTo compare the difference in morbidity and mortality of patients with multiple rib fractures undergoing SSRF who have underlying PCM to those who do not have PCM.MethodsWe performed a retrospective cohort study of patients with multiple rib fractures using data from the Trauma Quality Improvement Program (January 2015 to December 2018). Patients with penetrating injuries, those who died within the first 24 h, those with substantial head, spine, or abdominopelvic injuries, and those who were pregnant, were excluded. A PCM was defined as chronic lower respiratory disease, active smoking, or morbid obesity. Dichotomous outcomes were adjusted for potential confounders by creating a propensity score for PCM and applying inverse probability weighting. The propensity score accounted for multiple patient-level and hospital level covariates. Continuous outcomes were adjusted for these same covariates using multivariable quantile regression.ResultsOf the 4,084 patients who underwent SSRF, 3048 (75%) were males, the median age was 57 years [IQR 47, 66], and 1504 (37%) had at least one PCM. After adjusting for the propensity score, patients with PCM who underwent SSRF had no significant difference in mortality compared to those without PCM (absolute difference, 0.7% [95% CI -0.2, 1.7]). Similarly, there was no significant difference in time on the ventilator (0.6 days [-0.1, 1.4]). Patients with PCM, however, had a statistically significantly longer hospital LOS (0.8 days [0.3, 1.3]) and ICU LOS (0.6 days [0.1, 1.1]), higher risk of tracheostomy (2.7% [0.1, 4.6]) and higher probability of pulmonary complications (2.7% [1.2, 4.2]), compared to those without PCM.ConclusionAmong patients with multiple rib fractures who undergo SSRF, having a PCM did not result in a clinically important higher probability of dying or experiencing substantial morbidity. This factor should not exclude patients with PCM from receiving SSRF for multiple rib fractures but the small increased risk in morbidity should be discussed with patients prior to SSRF.Copyright © 2023 Elsevier Ltd.
