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.
Detailed description
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.
