The Pre-POCT-Non-Conveyance Trial: Prehospital Point-of-Care Testing to Support Non-Conveyance Decisions

Inclusion Criteria: * Adults aged ≥18 years * Emergency call or general practitioner-commissioned ambulance dispatch following telephone triage only, including video streaming triage, resulting in ambulance dispatch * Initial on-scene assessments performed by the ambulance crew * Patients initially considered for hospital conveyance based on clinical assessment * Following telemedical consultation with an Emergency Medical Dispatch Centre (EMDC) physician, deemed eligible for point-of-care blood testing (POCT) * Hemodynamically and clinically stable according to predefined operational stability criteria (including Glasgow Coma Scale, blood pressure, oxygen saturation, and heart rate), with final eligibility determined by the EMDC physician based on overall clinical assessment and the patient's baseline status Exclusion Criteria: * Non-emergency calls (e.g., interfacility transport or scheduled patient transport) * General practitioner-commissioned ambulance dispatches where the patient has been physically assessed by a general practitioner or another physician before ambulance arrival * Immediate need for emergency transport to hospital as determined by clinical assessment * Persistent unstable vital signs outside predefined operational thresholds, except for known chronic baseline deviations (e.g., reduced oxygen saturation in patients with chronic obstructive pulmonary disease or chronic tachyarrhythmia in atrial fibrillation) * Inability to obtain venous or capillary blood samples * Prior participation in the study within 30 days (to ensure complete outcome follow-up)
