Heat and sun related medical concerns in Australian led outdoor activities: a three-year prospective study
An analysis of Australian incident reports found heat and sun illness in led outdoor activities linked to participant, equipment and environmental factors that system-focused approaches could reduce.
What's new
Researchers prospectively collected cases over three years (2014–2017) from a national Australian incident reporting system for led outdoor activities, selecting them by keywords linked to heat or sun exposure. Of 2,015 incidents, 48 cases were included: 25 termed heat stroke and 23 other heat- or sun-related adverse outcomes. About a third (35%) occurred during outdoor walking or running and one in four while camping. Analysis found 146 contributory factors relating to the participant (such as competence and decision making), equipment and resources (such as food, drink and dehydration), and the environment (such as hot weather). The authors suggest system-focused approaches to mitigation and wider shared responsibility for prevention.
Why it matters in Aotearoa
Hot-weather events are an increasing consideration for EOTC in Aotearoa. The study supports looking beyond the individual participant to system-level planning for heat and sun risk.
Putting it into practice
Add heat and sun illness explicitly to your EOTC risk management plans for walking, running and camping activities, covering hydration, food, weather monitoring and recognising early signs and symptoms.
How strong is the evidence
This is a descriptive analysis of incident reports from one national system. Small case numbers and reliance on reporting and keyword selection limit the conclusions.
