Surgical stabilization of rib fractures: The impact of volume and the need for standardized indications.

Introduction: We aimed to examine impact of trauma center (TC) surgical stabilization of rib fracture (SSRF) volume on outcomes of patients undergoing SSRF.

Methods: Blunt rib fracture patients who underwent SSRF were included from ACS-TQIP2017-2021. TCs were stratified according to tertiles of SSRF volume:low (LV), middle, and high (HV). Outcomes were time to SSRF, respiratory complications, prolonged ventilator use, mortality.

Results: 16,872 patients were identified (LV:5470,HV:5836). Mean age was 56 years, 74% were male, median thorax-AIS was 3. HV centers had a lower proportion of patients with flail chest (HV41% vs LV50%), pulmonary contusion (HV44% vs LV52%) and had shorter time to SSRF(HV58 vs LV76 ​h), less respiratory complications (HV3.2% vs LV4.5%), prolonged ventilator use (HV15% vs LV26%), mortality (HV2% vs LV2.6%) (all p ​< ​0.05). On multivariable regression analysis, HV centers were independently associated with reduced time to SSRF(β ​= ​-18.77,95%CI ​= ​-21.30to-16.25), respiratory complications (OR ​= ​0.67,95%CI ​= ​0.49-0.94), prolonged ventilator use (OR ​= ​0.49,95%CI ​= ​0.41-0.59), but not mortality.

Conclusions: HV SSRF centers have improved outcomes, however, there are variations in threshold for SSRF and indications must be standardized.

Level Of Evidence: Level III.

Study Type: Therapeutic/Care Management.
