Five-level emergency triage systems [9–13].

BackgroundAccidental hypothermia, defined by a core temperature MethodsIn this retrospective cohort (2020–2024) at Semmelweis University, adults with measured tympanic temperature ResultsA total of 131 patients met the inclusion criteria. Median age was 67.0 years (IQR 59.0–75.0); 88 (67.2%) were male. Median admission temperature was 29.3 °C (IQR 26.1–31.4 °C); 47 (35.9%) had severe hypothermia (ConclusionsDespite milder winters, accidental hypothermia still carries substantial early mortality. Integrating admission temperature into a general triage system enhances prognostication and may guide rapid escalation of care. Our findings suggest the need for systematic surveillance, focused clinician education, and targeted resources to protect vulnerable patients in increasingly variable climates.
