Kangasniemi H, Setälä P, Olkinuora A, et al. - Given the scarcity of data on the withdrawal of life‐sustaining therapies and limitation of care orders (LCOs) during physician‐staffed Helicopter Emergency Medical Service (HEMS) missions, researchers here examined LCOs and the quality of information available when physicians made treatment decisions in prehospital care. In this prospective, nationwide, multicentre study, inclusion was performed of all Finnish physician‐staffed HEMS bases during a 6‐month study period. There were 335 missions with LCOs representing 5.7% of all HEMS missions (n = 5,895). Per observations, HEMS physicians’ work integrally involve making LCOs or treating patients with pre‐existing LCOs, with every twentieth mission involving LCO patients. When the physician made treatment decisions, there was availability of patients’ background information from on‐scene paramedics in 260 (78%) of the LCO missions, while there were patients’ medical records available in 67 (20%) of the missions. Mostly, the new LCOs referred to withholding or withdrawal of cardiopulmonary resuscitation and intensive care.
