dc.description Abstract of the Undersea and Hyperbaric Medical Society, Inc. Annual Scientific Meeting held June 14-16, 2007. Ritz-Carlton Kapalua Maui, Hawaii (http:www.uhms.org) en
dc.description.abstract BACKGROUND: The Pareto principle states that for many phenomena, a few vital causes are responsible for most failures, and thus, failures can be effectively reduced by minimizing these causes. We applied this principle to identification of possible causes (or associations) in diving deaths. MATERIALS AND METHODS: For each of 974 recreational diving deaths collected by DAN from 1992-2003, we attempted to identify an event sequence that included a trigger (the earliest adverse event, e.g., insufficient gas), harmful action (HA, an adverse event immediately preceding the disabling event, e.g., emergency ascent), disabling event (DE, e.g., arterial gas embolism (AGE)), and cause of death (COD, e.g., drowning). COD and DE were ascertained from possible causes listed in medical examiner reports (MER). When more then one possible cause was mentioned, the earliest was defined as the DE. RESULTS: In the absence of other causes in MER, drowning was the COD in 70% of 862 cases where COD could be identified, but since drowning can result from DE that lead to incapacitation or unconsciousness, we concluded that DE was more informative than COD. Of 602 cases for which DE could be identified, drowning was assigned in 32%, AGE in 29%, and cardiac incidents in 26%. Other DEs were rare and ascribed to trauma (6%), decompression sickness (3%), loss of consciousness (2%), and inappropriate gas (2%). Drowning, AGE, and cardiac incidents had characteristic HA and triggers. In drowning, 79% of HA and 72% of triggers involved entrapment or insufficient gas. In AGE, 96% of HA involved emergency ascent while 83% of triggers included insufficient gas or equipment trouble. Cardiac incidents were seldom preceded by identifiable HA or triggers. CONCLUSIONS: According to the Pareto principal, interventions that decreased entrapment, insufficient gas, emergency ascent, and equipment problems would have the greatest impact on reducing diving deaths. en
