This study assessed the utility of lifeguard rescue data for providing information on person and situation factors to inform surf bather drowning prevention research.
The dataset comprised 872 beach-days (daily lifeguard reports) obtained from 26 beaches over a 95-day period in Victoria, Australia.
The rescue rate was 128 per 100,000 in-water bathers. One or more rescues were required on 125 beach-days (14%). Rescue on a beach-day was more likely for offshore wind conditions, relatively high daily air temperatures, and high bather numbers (P < .05). Compared to female bathers, males were more frequently rescued (65%) and more likely (P < .05) to be from a younger age group (30 years or less), although being older was associated with a relatively poorer condition on rescue.
Although rescues are proportional to water exposure, frequencies are also influenced by situation and person factors. Bathers at relatively high risk of rescue are hypothesized to be overrepresented in amenable sea and weather conditions, and poor patient condition on rescue may be associated with exposure to a preexisting health condition.
本研究评估了救生员救援数据在提供人员和情境因素信息以指导冲浪者溺水预防研究方面的效用。
数据集包括在澳大利亚维多利亚州95天内从26个海滩获取的872个海滩日(每日救生员报告)。
每100,000名在水中的冲浪者的救援率为128。在125个海滩日(14%)需要进行一次或多次救援。在离岸风况、相对较高的每日气温和较高的冲浪者数量的情况下,在海滩日进行救援的可能性更大(P <.05)。与女性冲浪者相比,男性被救援的频率更高(65%),且更有可能(P <.05)来自较年轻的年龄组(30岁或以下),尽管年龄较大与救援时的相对较差状况有关。
虽然救援与水中暴露成正比,但频率也受情境和人员因素影响。据推测,在适宜的海洋和天气条件下,救援风险相对较高的冲浪者比例过高,且救援时患者状况不佳可能与先前存在的健康状况暴露有关。
