ROSC nomogram from a physician-led EMS
Influencing factors analysis and prediction model development for ROSC in adult non-traumatic OHCA: a retrospective study based on pre-hospital emergency settings
Annals of Medicine · 2026-10-14 · Added 16 October 2026
Chinese retrospective study of 9,386 non-traumatic OHCA cases built a ROSC prediction nomogram (AUC 0.775) from factors including shockable rhythm, intubation and — unique to physician-staffed systems — the attending physician's sex and seniority.
- Study type
- Cohort
- Design
- Retrospective cohort with nomogram development
- Participants
- 9,386 adult non-traumatic OHCA cases, Tianjin 2023–2024
- Main finding
- 7.2% achieved sustained ROSC; independent predictors included shockable initial rhythm (aOR 2.85), intubation (aOR 2.29) and public location (aOR 1.29), with a nomogram AUC of 0.775
- Caveat
- Single-centre retrospective data from a physician-dispatch system, internally validated only
- Bottom line
- Context only
Why it matters in Australia (Low relevance). Physician-staffed Chinese EMS model — predictors like physician sex, title and years of practice simply don't exist in Australian paramedic-led systems.
Learning goal
Weigh how initial rhythm, airway management and arrest location shape my prognostication for return of spontaneous circulation in out-of-hospital cardiac arrest.

Every minute counts: early bystander CPR
A time-to-event analysis of the All-Japan Utstein registry found overall bystander CPR rates stayed stable through the pandemic, but initiation within 10 minutes slipped — and earlier starts sharply improved neurological outcomes (aOR 3.27 for 0–3 min vs >10 min).

Commotio cordis outcomes hinge on fast AED
A nationwide Japanese school-sports database reconstructed 30 sports-related OHCAs from external causes and found commotio cordis cases did dramatically better when AEDs were applied fast — 80% favourable neurological outcome — while other external causes fared poorly.

Signs of life in traumatic OHCA
Retrospective analysis of 462 adults with traumatic OHCA from a Japanese prospective registry found 4.8% survived beyond the ED, with the best survival where scene cardiac activity and spontaneous respiration coexisted (25%).

Dispatcher CPR and survival in shockable OHCA
Nationwide Hungarian cohort of 3,674 shockable OHCAs found dispatcher-assisted CPR ongoing at ambulance arrival was associated with far better outcomes than crew-initiated CPR — 30-day survival 54.6% vs 7.1% and one-year survival 45.8% vs 6.2%.
