Paramedic Papers Daily — 24 October 2026

Seven new papers today — here are the top four. Paper one — younger adults, men, people born overseas and remote residents are all less likely to call an ambulance for chest pain. Paper two — prehospital ultrasound can sharpen decisions in arrest, shock and breathlessness, but it can't rule anything out. Paper three — an American state widened its paramedic oxytocin scope, and the transferable part is how the change was won. Paper four — helicopter crews follow trauma guidelines more consistently than road crews, in a registry of nearly one hundred and thirty thousand patients.

Paper one — Open Access Emergency Medicine. A systematic review of fourteen Australian studies asking a simple question — who doesn't ring for an ambulance when chest pain hits? Ambulance use for acute coronary syndrome ranged from thirty-six to seventy-nine per cent, and the gaps were consistent. Adults under forty-nine had up to sixty-eight per cent lower odds of calling than those over sixty-five. Men up to eleven per cent lower than women. People born overseas up to fifteen per cent lower, those preferring a language other than English six to twenty per cent lower, and remote residents up to twenty-five per cent lower than major-city residents. One group bucked the trend — people living alone had up to forty-eight per cent higher odds. The main caveat is method — this is a vote-counting synthesis of varied observational studies, not pooled estimates. Still, for crews, it's a reminder that the patients who most need the ambulance aren't always the ones who call it.

Paper two — The Ultrasound Journal. A structured narrative review of thirty-eight articles on point-of-care ultrasound before hospital. In cardiac arrest, it can identify cardiac activity and some reversible causes, confirm return of spontaneous circulation, and support prognostic decisions — provided getting the image doesn't interrupt compressions or delay defibrillation. In undifferentiated shock, focused cardiac and lung scans can help characterise the mechanism. In cardiogenic pulmonary oedema, lung ultrasound improves diagnostic confidence. In trauma, E-FAST is highly specific, so a positive scan can support triage and destination decisions — but sensitivity is too limited to ever be a rule-out test. The caveat: one reviewer, no formal risk-of-bias assessment, no meta-analysis. And the relevance here is mostly forward-looking — prehospital ultrasound is carried by only a handful of Australian services, most crews don't have it, so this shapes the adoption debate more than today's practice.

Paper three — Journal of Midwifery and Women's Health. A quality improvement write-up from Utah, a rural American state where prehospital births are common and paramedic coverage is thin. Before March of twenty twenty-four, paramedics there could give oxytocin only to treat postpartum haemorrhage — never to prevent it — and advanced EMTs couldn't give it at all. After a community coalition ran interviews, focus groups and stakeholder surveys, the state protocols changed that April. Paramedics can now give oxytocin to prevent postpartum haemorrhage, and advanced EMTs can give it intramuscularly for prevention and treatment. Oxytocin itself is on nearly every Australian service's drug list, so the drug isn't the news — the playbook for widening scope of practice is. The caveat: it's a single-state process description with no clinical outcome data.

Paper four — European Journal of Trauma and Emergency Surgery. A retrospective analysis of one hundred and twenty-nine thousand, seven hundred and eighty-three severely injured adults from the German trauma registry, a quarter of them flown in by helicopter. The helicopter patients were younger and more severely injured, but even within matched indication subgroups, the helicopter crews intervened more — advanced airway in impaired consciousness ninety-six point five per cent versus eighty-two point nine, and chest drains fifty point five per cent versus forty point nine. The caveats: it's a descriptive analysis using registry variables as surrogates for indications, with no adjustment for confounding. And translation needs care — this is a physician-staffed model, and chest drains sit well beyond Australian paramedic scope. But the question of who gets the helicopter, and what they get done en route, is a live one here too.

Quick recap. One — chest pain ambulance calls run low in younger adults, men, the overseas-born and remote residents. Two — prehospital ultrasound supports decisions in arrest, shock and breathlessness, but can't rule anything out. Three — Utah widened paramedic oxytocin scope, and the change process is the takeaway. Four — helicopter crews hit guideline-recommended trauma interventions at higher rates than road crews.

Also on the dashboard today — paramedics on digital decision support, cluster trials read differently to individual ones, and hot days driving dizziness call-outs. That's the roundup for Saturday the twenty-fourth of October. Back tomorrow.
