Brief Summary

A recent study reported significantly increased mortality from drowning-related out-of-hospital cardiac arrest in Danish harbours compared to other public places (e.g., public pools, coastlines, and lakes). Accurate and reliable data are necessary before establishing specific educational, preventative, rescue, or treatment strategies to reduce the number of drowning incidents in Danish harbours and improve survival. Therefore, it is essential to characterise drowning incidents in Danish harbours and analyse risk factors associated with fatal drowning.

Outcome Measures

Primary Outcomes (2)

• Yearly incidence of drowning incidents

  Yearly incidence of fatal and non-fatal drowning incidents in Danish harbours treated by the EMS from 2016-2023

  30 days after the drowning incident

• Fatal to non-fatal drowning ratio

  Cumulated counts of fatal to non-fatal drowning incidents from 2016-2023

  30 days after the drowning incident

Secondary Outcomes (1)

• Assess risk factors associated with 30-day mortality

  30 days after the drowning incident

Study Arms (2)

Fatal drowning

This group of patients experienced a drowning incident defined as the process of experiencing respiratory impairment from submersion or immersion in liquid and died within 30 days after the incident as a consequence of the submersion injury.

Other: Drowning

Non-fatal drowning

This group of patients experienced a drowning incident defined as the process of experiencing respiratory impairment from submersion or immersion in liquid and survived until 30 days after the incident.

Other: Drowning

Interventions

Drowning OTHER

Drowning is defined as the process of experiencing respiratory impairment from submersion or immersion in liquid.

Fatal drowning; Non-fatal drowning

Eligibility Criteria

• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

The target condition in this study is drowning, irrespective of follow-up at 30 days (fatal or non-fatal). We used the WHO definition of drowning supported by the clarification statement for non-fatal drowning as the case definition to identify drowning (target condition) during the manual validation. The study unit is the individual drowning patient. The target population are all fatal and non-fatal drowning patients in Danish harbours treated by the EMS in Denmark since 2016. Due to the comprehensive search criteria in the Danish Drowning Formula, it is reasonable to believe that the target population is identical to the study population.

You may qualify if:

• Incidents registered at GPS coordinates corresponding to a Danish harbour OR
• Incidents identified using advanced text-search algorithm searching for "harbour"-related words

You may not qualify if:

• Patients without a 30-day follow-up (e.g., due to missing or invalid civil registration numbers) and patients with a valid DNAR code will be excluded from the mortality analysis.
