About this trial

This study aims to 1) describe patient-, setting-, and dispatcher-related characteristics in drowning-related emergency calls to the Emergency Medical Dispatch Centre (1-1-2 emergency phone) and 2) factors associated with 30-day survival. The investigators will separately analyse drowning-related out-of-hospital cardiac arrest (OHCA) and drowning-related non-OHCA. If feasible, the investigators will qualitatively analyse the calls to identify and describe potential barriers for an optimal handling strategy.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients at all ages registered in the Danish Prehospital Drowning Data are eligible.

Disqualifiers

Obvious clinical signs of irreversible death (decapitation, decomposition, post-mortem lividity, post-mortem rigidity)

A valid Do-Not-Attempt-Resuscitation (DNAR) order or other code status orders limiting life-sustaining therapies

Missing or corrupted audio files

Missing identification number

Trial population

All validated drowning cases registered in the Danish Prehospital Drowning Data will be linked with data from the EMDC database according to a data minimisation principle. Patients are included in the Danish Prehospital Drowning Data if they have experienced a drowning incident between 2016 and 2023, defined as experiencing respiratory impairment from submersion or immersion in liquid.

Time perspective

Retrospective

Treatments tested in this trial

  • Drowning-related OHCA

    Other intervention

    These patients were involved in a drowning incident (submersion or immersion in liquid) and experienced out-of-hospital cardiac arrest (OHCA), defined as being unconscious and not breathing normally at any time in the prehospital setting. Some of these patients may die as a consequence of the submersion injury (fatal drowning), while others may survive (non-fatal drowning).

  • Drowning-related non-OHCA

    Other intervention

    These patients were involved in a drowning incident (submersion or immersion in liquid) but did not experience an OHCA. Some of these patients may die as a consequence of the submersion injury (fatal drowning), while others may survive (non-fatal drowning).
