Paramedic Papers Daily — 11 November 2026

Seven new papers today — here are the top four. Paper one — the first year of a Sydney trauma shock registry: two hundred and fifty-seven patients, over half given blood before hospital, twenty-one per cent dead at thirty days. Paper two — a French study of roadside capillary troponin for chest pain. Paper three — UK bystander CPR is rising, but defibrillator use isn't. Paper four — augmented-reality guidance helped paramedic students scan faster in trauma ultrasound.

Paper one — Emergency Medicine Australasia. A prospective, multi-centre registry — the Sydney COAST study — reporting its first twelve months of shocked major trauma patients. Two hundred and fifty-seven adults, all in shock before hospital, taken straight to a Sydney major trauma centre. Hypotension was the shock criterion in ninety per cent of cases. Fifty-three per cent received a blood transfusion before hospital, thirty-one per cent needed interventional haemorrhage control, and seventy-four per cent were transfused once in hospital. Injuries were severe — a median injury severity score of twenty-seven. Mortality was four point seven per cent at four hours, nine per cent at twenty-four hours, and twenty-one per cent at thirty days. Prehospital blood is still limited to a few Australian services, so the shock epidemiology here travels nationally even where the blood component doesn't. It's a preliminary descriptive report — no outcome comparisons — and not all of these shocked patients were bleeding.

Paper two — the European Journal of Emergency Medicine. The VALIDATE study — a prospective, multi-centre diagnostic accuracy study across four French emergency medical systems, with ten mobile intensive care units. Adults with acute chest pain had a finger-prick capillary sample tested on a hand-held device for high-sensitivity troponin, and the treating clinicians were blinded to the result. The question: how well does a roadside troponin pick up NSTEMI at discharge? The indexed abstract doesn't report the headline numbers yet, so hold off on the precision for now. Two things temper it anyway — the French systems are physician-staffed, and point-of-care troponin isn't something Australian ambulances carry. Still an interesting direction — an answer at the roadside means faster triage decisions.

Paper three — the Journal of Paramedic Practice. A PRISMA-guided literature review of out-of-hospital cardiac arrest across the UK — five hundred and forty-four articles screened, eight included. The pattern: bystander CPR rates are increasing in England and Scotland, but AED use in cardiac arrest has shown little improvement. Intervention rates also tracked demographics and socioeconomic factors. It's a small review — eight papers spanning four health systems — so read it as a snapshot rather than a verdict. But the CPR-up, defibrillator-flat pattern is the same one Australian cardiac arrest registries keep describing — the chain of survival still breaks at the defibrillator link.

Paper four — Simulation in Healthcare. A small Japanese training study — eighteen undergraduate paramedic students, a two-hour program of a lecture plus hands-on scanning, and four FAST scans each: two conventional, two guided by augmented reality. Median total scan time fell by two hundred and sixty-three and a half seconds — call it four and a half minutes — and both quality scores improved significantly. Every view got faster except the Douglas pouch view. Big caveat: no parallel control group and a fixed scan sequence, so some of that gain is just practice. Point-of-care ultrasound is carried by a handful of Australian services, most don't — but for training, cheap augmented-reality guidance that speeds up learning looks worth a look.

Quick recap. One — a Sydney registry of two hundred and fifty-seven shocked trauma patients: half got prehospital blood, twenty-one per cent dead at thirty days. Two — roadside capillary troponin for chest pain looks promising in France, but no numbers yet and it's a physician-led model. Three — UK bystander CPR is up, AED use is flat. Four — augmented-reality guidance cut FAST scan times for paramedic students, in a small, uncontrolled study.

That's the roundup for Wednesday the eleventh of November. Also on the dashboard today — fibrinogen concentrate supply growing in Queensland, paramedic and midwifery students training together, and autonomy and support driving paramedic wellbeing. Back tomorrow.
