The creation of an airway registry will allow an improvement in the quality of care, the safety of critically ill patients in pre-hospital situations, and a reduction in morbidity and mortality related to airway management.

In the care of critically ill patients in prehospital emergency settings, advanced airway management (AAM) is essential to maintain airway patency and ensure adequate oxygenation and ventilation. In Andalusia, prehospital emergency teams are composed of a physician, a nurse, and an emergency medical technician (EMT), and they operate both ground units (advanced life support ambulances) and air units (medical helicopters).

AAM encompasses a wide range of processes, techniques, and complex decision-making interventions that can be key to favorable patient outcomes. However, if not performed correctly, these procedures can also lead to adverse events, poor prognosis, or preventable mortality.

The increasing complexity and technological sophistication of healthcare require health systems to improve and adapt in order to deliver safe, high-quality care, where continuity and an integrated vision of care are essential.

This comprehensive approach is made possible through the analysis of incidents recorded in registries, which play a key role in identifying failures in clinical practice and implementing new strategies to address them.
