Definitive management of near-hanging at major versus non-major trauma centres

Objectives: The Victorian State Trauma System recommends that all major trauma patients receive definitive care at a major trauma service (MTS). The aim of the present study was to assess the outcomes of patients with major trauma after near-hangings who received definitive management at an MTS compared to a non-MTS. Methods: This was a registry-based cohort study of all adult (age ≥16 years) patients with near-hanging included in the Victorian State Trauma Registry from 1 July 2010 to 30 June 2019. Outcomes of interest were death at hospital discharge, time to death and extended Glasgow Outcome Scale (GOSE) score of 5–8 (favourable) at 6 months. Results: There were 243 patients included and 134 (55.1%) in-hospital deaths. Among patients presenting to a non-MTS, 24 (16.8%) were transferred to an MTS. There were 59 (47.6%) deaths at an MTS and 75 (63.0%) at a non-MTS (odds ratio [OR] 0.53; 95% confidence interval [CI] 0.32–0.89). However, more patients were managed at a non-MTS after out-of-hospital cardiac arrest (58.8% vs 50.8%) and less patients had serious neck injury (0.8% vs 11.3%). After adjustment for out-of-hospital cardiac arrests and serious neck injury, management at an MTS was not associated with mortality (adjusted OR [aOR] 0.61; 95% CI 0.23–1.65) or favourable GOSE at 6 months (aOR 1.09; 95% CI 0.40–3.03). Conclusions: After major trauma sustained from near-hanging, definitive management at an MTS did not offer a mortality benefit or better functional outcomes. Consistent with current practice, these findings suggest that most near-hanging related major trauma patients could be managed safely at a non-MTS.
