Abstract

Abstract : BACKGROUND: Western Trauma Association guidelines recommend admitting patients 65 years or older with two or more rib fractures diagnosed by chest radiograph to the intensive care unit (ICU). Increased use of computed tomography has led to identification of less severe, "occult" rib fractures. We aimed to evaluate current national trends in disposition of older patients with isolated rib cage fractures and to identify characteristics of patients initially admitted to the ward who failed ward management. METHODS: A retrospective cohort study of patients 65 years or older with isolated two or more blunt rib cage fractures using the 2010 to 2016 American College of Surgeons Trauma Quality Improvement Program database was performed. Ward failure was defined as patients initially admitted to the ward with subsequent need for unplanned ICU admission or intubation. Multivariable analyses were derived to study the independent predictors of failure of ward management. Propensity score matching sub-analysis was used to assess outcomes in patients admitted to the ward versus ICU. RESULTS: There were 5, 021 patients included in the analysis. Of these patients, 1, 406 (28.0%) were admitted to the ICU. On multivariable analysis, age was an independent predictor of ICU admission. Of the 3, 577 patients admitted directly to the ward, 38 (1.1%) patients required unplanned intubation or ICU admission. Independent predictors of failure of ward management included chronic renal failure (odds ratio [OR], 7.20; p ⩽ 0.001; 95% confidence interval [CI], 2.50–20.76), traumatic pneumothorax (OR, 8.70; p = 0.008; 95% CI, 1.76–42.93), concurrent sternal fracture (OR, 6.52; p ⩽ 0.001; 95% CI, 2.53–16.80), drug use disorder (OR, 6.58; p = 0.032; 95% CI, 1.17–36.96), and emergency department oxygen requirement or oxygen saturation less than 95% (OR, 2.38; p = 0.018; 95% CI, 1.16–4.86). Mortality was higher in patients with delayed ICU care versus patients with successful ward disposition (21.1% vs. 0.8%; p < 0.001). CONCLUSION: Our results suggest that the majority of isolated rib cage fractures in older patients are safely managed on the ward with exceedingly low ward failure rates (1.1%). Patients with failure of ward management have significantly higher mortality, and we have identified predictors of failing the ward.
