Need for consistent beach lifeguard data collection: results from an international survey.

Inconsistencies in lifeguard data collection present challenges to operations, safety education and prevention efforts, research and policy relying on these data. Variation in definitions, methods and collected variables generally restricts analysis to a single BLSP with limited generalisability to other beach settings. Some gaps in lifeguard data collection may soon be addressed by technology, but developing uniform, internationally acceptable standards and definitions should be prioritised.
