[Physician-led healthcare structures for patients in out-of-hospital intensive care nursing: a cross-sectional survey by the German Society for Out-of-Hospital Ventilation].

Background: Patients in out-of-hospital intensive care are usually provided with a tracheal cannula and often additionally receive mechanical ventilation. Less frequently, they receive non-invasive ventilation. Their potential to be weaned from the ventilator and to have their tracheostomy tubes removed must be evaluated twice per year from January 1, 2025 on. If there is a potential for weaning from mechanical ventilation or removal of the tracheostomy tube, referral to a specialized facility is required.

Objective: The study aimed at characterizing the specialized institutions which can evaluate the potential of patients to be weaned from the ventilator and to have their tracheostomy tubes removed, and which can perform these tasks as well.

Methods: Under the auspices of the German Interdisciplinary Society for Out-of-Hospital Ventilation (DIGAB) and with support from the Working group early neurological-neurosurgical rehabilitation (ENNR) a crosssectional online survey took place.

Results: Of 18 participating institutions, 11 (61.1%) were certified by professional societies representing neurorehabilitation, respiratory medicine, anaesthesiology and intensive care or paraplegiology. Most leading physicians were specialists in neurology, followed by pulmonology, anaesthesiology and paediatrics. Many professions with a variety of qualifications worked in these institutions. According to n=10 (55.6%) of the participating instituions, regional treatment capacities for patients from out-of-hospital intensive care, who need hospital admission for weaning from mechanical ventilation or a tracheal cannula, were not sufficient. About one third of the institutions offered televisits.

Discussion: Patients in out-of-hospital intensive care need interdisciplinary care, interconnecting out- and inpatient care structures due to medical complexity and participation restrictions. While interdisciplinary teams and a wide spectrum of diagnostic and therapeutic methods were provided in the participating institutions, their structure differed considerably.

Conclusion: Quality criteria should be established for centres evaluating the patients' potential to be weaned from the ventilator and to have their tracheostomy tubes removed and performing weaning from mechanical ventilation and tracheal cannulas. Further research is needed to specify those criteria, to quantify inpatient treatment capacities for patients from out-of-hospital intensive care to be weaned from mechanical ventilation or tracheal cannulas,to evaluate the feasibility of weaning from mechanical ventilation and tracheal cannulas in an out-of-hospital setting and to understand the role of telemedicine in the treatment of patients in out-of-hospital intensive care.
