Public rescue tube deployment in Hawaii: protective association with rescuer drownings.

OBJECTIVE: To describe the association between public rescue tube (PRT) flotation devices and fatal rescuer drownings in Kauai, Hawaii. METHODS: We reviewed Hawaii death certificate data from 1993 to 2017, sometimes supplemented with autopsy and emergency medical service reports, to identify fatal rescuer drownings. Incidents were analysed in relation to the initial 2008 deployment of PRT. RESULTS: Over the 25-year period, only 13% (228) of the 1750 identified drownings occurred in Kauai, but nearly half (46%, or 13) of the 28 rescuer deaths occurred there. However, only 1 of the 13 rescuer deaths in Kauai occurred after the 2008 deployment of PRT. The state-wide proportion of rescuer deaths in Kauai decreased significantly from 60% (12 of 20) from 1993 to 2007 to 13% (1 of 8) from 2008 to 2017. There were no apparent changes in the proportions of rescuer drownings in the other three counties of the state, where PRTs were essentially non-existent. CONCLUSION: Despite valid concerns, we found no fatal rescuer drownings related to PRT use after their 2008 introduction in the county of Kauai. Instead, we observed a reduction in the number of rescuer drownings, and in their proportion of total drownings in association with the deployment of PRT. The findings of this study have the potential to directly impact ocean and other open water environment-related fatal drowning prevention policy and practice.

Unique Epidemiology of Spinal Cord Injury in Hawai'i: Wave-related Incidents.

Spinal cord injury remains one of the most devastating forms of traumatic injury. The purpose of this study was to characterize the clinical characteristics of spinal cord injury patients and the geographic location where the injury occurred in the state of Hawai'i. Spinal cord injury cases from 2009-2017 were identified using the State Trauma Registry, which included demographics, mechanism of injury, and outcomes. In 1170 spinal cord injury cases, the second most frequent etiology was an ocean-wave related incident. Over half of wave related spinal cord injury occurred on ten beaches on four islands. Compared to other mechanisms, patients with wave related spinal cord injury were significantly less likely to be Hawai'i residents (15%), screen positive for alcohol (4%), or have an injury in the lower thoracic or lumbar region (4%). These patients were also less likely to die (1%) and more likely to be discharged to home (66%). Wave related incidents are a major cause of spinal cord injury in Hawai'i, disproportionately affecting visitors. Education focused toward middle-aged male visitors at beaches with moderate to severe shorebreak may reduce the incidence of injury.
