The Emergency Call on Drowning

The Emergency Call on Drowning: A Registry-based Cohort Study of the Characteristics, Predictors, and Outcomes of Fatal and Non-fatal Drowning

Sponsor

Prehospital Center, Region Zealand

Enrollment

1,500 participants

Start Date

Jan 1, 2016

Study Type

OBSERVATIONAL

Conditions

Drowning Drowning; Anoxia Drowning, Near Drowning; Asphyxia Drowning and Nonfatal Submersion Drowning or Immersion of Unknown Intent Drowning and Submersion, Undetermined Intent Drowning and Submersion While in Bath-Tub Drowning and Submersion While in Natural Water Drowning and Submersion Due to Sailboat Sinking Drowning and Submersion Due to Fall Off Ship Drowning and Submersion While in Swimming-Pool

Summary

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

Inclusion Criteria1

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

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
Missing 30-day survival

Interventions

OTHERDrowning-related OHCA

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).

OTHERDrowning-related non-OHCA

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).
