The effect of the 'Swim Reaper' program on water safety awareness, drowning mortality and morbidity among males aged 15-34 years in Aotearoa, New Zealand.

BACKGROUND AND OBJECTIVE: To increase water safety awareness among young males New Zealand introduced the Swim Reaper program in 2016. The program ran annually over summer and in 2018/19 an evaluation was conducted. The objective of this study was to evaluate the impact of the 2018/19 Swim Reaper social media-based campaign on self-reported water safety awareness and identify changes in fatal and nonfatal drowning rates for New Zealand resident males aged 15-34 years before and after the 2016 Swim Reaper program. METHODS: Online surveys pre (December-2018) and post (February-March-2019) Swim Reaper campaign were used to estimate water safety awareness post-campaign relative to pre-campaign using negative binomial regression adjusted for potential confounders. Interrupted time series (ITS) analysis, adjusted for seasonality, explored changes in drowning mortality, hospital admissions and Accident Compensation Corporation (ACC) claims pre and post program introduction (2016). RESULTS: A total of 518 males responded (50.6% post-campaign). There were significant improvements (post vs. pre-campaign) in self-reported water safety awareness. ITS analysis showed a reduction in drowning related hospital admissions post relative to pre-program (RR = 0.47; [95%CI: 0.24-0.90]; p = 0.02). DISCUSSION: Young males are an at-risk cohort for drowning and creating behavior change among this group can be challenging. Using a unique, humor-based approach the Swim Reaper program appears to be having some impact on self-reported water safety behaviors, as well as unintentional drowning-related hospitalization rates. Further evaluation, more clearly linked to campaign themes, is required to ascertain direct impact of the program. CONCLUSION: The novelty and reach of the campaign within the context of a prevailing downward trend in drownings may provide support for social media-based programs targeting this hard-to-reach demographic.

Fatal coastal drowning incidents: A 10-year review of body recovery times in New Zealand.

Despite drowning being a leading cause of unintentional injury worldwide, gaps in the data still exist. One area where limited data is available to guide lifeguards, police, search and rescue agencies, accident and forensic investigators, ocean scientists, and the coroner, is how far from the last known point (displacement) a missing person is likely to be found, and the time frame for this to occur. This lack of certainty can exacerbate the emotional toll on family, friends, and rescuers. This study aimed to describe body recovery times and displacement for fatal coastal drowning incidents in New Zealand. Using DrownBase™, the National Coronial Information System, and media reports, data were extracted for all fatal coastal-missing-person drowning incidents from 2008 to 2017. A total of 219 cases were selected. Almost all incidents involved males (92%) and minority groups (e.g., Maori and Pasifika) were over-represented. Older adults (> 42 years) were more likely to be engaged in boating, whereas for younger adults (≤ 42 years), it was swimming. Most missing persons were described as good swimmers (51%) and wearing everyday clothing (48%), yet only 4% wore a lifejacket. Most incidents were observed (63%), and rescue was attempted in 86% of cases. Most bodies (58%) were recovered within 24h, and only 15% were not found (9%) or not reported (6%). Most missing persons (64%) were either found in the same location (57%) or <1km from where they entered the water (7%). The quality of on-scene data limited some analysis, and the results of this study may not apply to all aquatic locations. Improved data collection could inform real-time predictive modelling of where and when a missing person might be found. The involvement of forensic and ocean scientists in future study design to widen applicability to these domains is also recommended. Fewer lives would be lost to drowning, however, if safer practices were adopted when recreating or working in, on, or around water.
