Critical care drowning admissions in Southwest England 2009-2020, a retrospective study.

Aim: In the United Kingdom (UK), 600 deaths per annum are attributable to drowning. Despite this there is scarce critical care data on drowning patients globally. We describe drowning cases admitted to critical care units with a focus on functional outcomes.

Materials and methods: Medical records for critical care admissions following a drowning event were retrospectively reviewed across six hospitals in Southwest England for cases presenting in the period between 2009 and 2020. Data was collected according to the Utstein international consensus guidelines on drowning.

Results: Forty-nine patients were included, 36 males and 13 females, including seven children. Median submersion duration was 2.5 min 20 cases were in cardiac arrest when rescued. At discharge 22 patients had preserved functional status, 10 patients had a reduced functional status. 17 patients died in hospital.

Conclusion: Admission to critical care following drowning is uncommon and associated with high rates of mortality and poor functional outcomes. We find that 31% of those who survived a drowning event subsequently required an increased level of assistance with their activities of daily living.
