Global GNOS site survey shows profound HDI‑linked gaps, especially prehospital and rehabilitation

Across 159 centres (153 responded) in the GNOS site survey, resource gaps for TBI care clustered in prehospital and rehabilitation phases. Operating theatre resources varied least across HDI strata while prehospital and rehab showed the largest disparities. Respondents most commonly ranked prehospital care improvements as having the greatest potential outcome impact, though lower‑HDI sites prioritized intensive care upgrades. Authors conclude strengthening non‑operative TBI interventions and prehospital systems may offer the largest global mortality gains. 1

MySurgeryRisk generalizes to multicenter data with high discrimination for major postop outcomes

In 508,097 encounters from 366,875 adults across 14 institutions, MySurgeryRisk predicted ICU admission (AUROC 0.93) and in‑hospital mortality (0.95). Postop mechanical ventilation and AKI were also well predicted (AUROCs 0.94 and 0.92 respectively). Procedure type and clinician‑specific variables were the dominant predictors across models. This supports using the framework for multicenter preoperative risk stratification, with local validation advised before clinical deployment. 2

Pilot RCT: VR plus eye‑tracking feedback outperforms mannequin training for situational awareness

In a pilot randomized trial of 35 interns, VR with eye‑tracking produced larger mean gains in situational awareness than mannequin training (Δ 6.59 vs 3.11). ATLS checklist performance improved more after VR (Δ 22.12 vs 8.22), and error scores fell further in the VR arm. Both modalities yielded significant within‑group improvements, but the study is small and exploratory. Findings support feasibility and justify larger trials before broad curricular adoption. 3
