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.
Based on the GPS coordinates and advanced text-searching, it is possible to identify drowning incidents in Danish harbours and extract data from the Danish Prehospital Drowning Data.
This study is a nationwide registry-based study with data from the Danish Prehospital Drowning Data from 2016 to 2023. In this study, we will use 30-day mortality to differentiate between fatal and non-fatal drowning.
The primary objective is to estimate the yearly incidence of fatal and non-fatal drowning incidents in Danish harbours treated by the EMS from 2016 to 2023 and calculate the fatal to non-fatal ratio. The secondary objective is to assess risk factors associated with 30-day mortality.
| Arm | Type | Interventions | Description |
|---|---|---|---|
| Fatal drowning | Other: 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. | |
| Non-fatal drowning | Other: 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. |
Sex: All
Inclusion Criteria: * All the patients registered in the Danish Prehospital Drowning Data from 2016-2023 will be assessed for inclusion AND * Incidents registered at GPS coordinates corresponding to a Danish harbour OR * Incidents identified using advanced text-search algorithm searching for "harbour"-related words Exclusion Criteria: * 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.
