Surgical Stabilization Improves 30-day Mortality in Patients With Traumatic Flail Chest: A Comparative Case Series at a Major Trauma Center.

OBJECTIVES

To evaluate the outcomes including early mortality after surgical rib fixation using a locking plate system as part of a newly introduced chest trauma pathway.

DESIGN

Prospective cohort study with retrospective case-controlled matching with a minimum of 1-year follow-up.

SETTING

Regional Level 1 trauma center.

PATIENTS/

PARTICIPANTS

Consecutive patients undergoing surgical rib fixation were prospectively recruited over a 3-year period (56 patients) and matched to similar patients managed nonoperatively (89 patients) using our local trauma registry. Matching was based on injury severity scores and patient demographics.

INTERVENTION: Surgical rib fixation with locking plates.

MAIN OUTCOME MEASUREMENTS: The primary outcome measure was 30-day mortality with secondary outcomes of hospital length of stay, intensive care unit length of stay, and patient-reported outcome measures including quality of life (EuroQol-EQ-5D-5L). Official causes of death were obtained from the coroner including postmortem results.

RESULTS

There was a significant reduction in 30-day mortality in the fixed patients with 1.8% (1/56) compared to 12.4% (11/89) of the nonfixed patients (P = 0.03). This difference remained significant after further exclusion of other nonsurvivable injuries (P = 0.046). Although hospital length of stay was significantly longer in the fixed group, there was no difference on multivariable analysis. Other secondary outcomes were comparable between the groups with no significant differences in any patient-reported measures.

CONCLUSIONS

Mortality was significantly lower in patients who underwent rib stabilization. Quality of life and other patient-reported measures were similar, demonstrating no evidence of detrimental longer-term effects of rib stabilization.
