Title: [abstract] ESTIMATED DCI INCIDENCE IN A SELECT GROUP OF RECREATIONAL DIVERS.
Author: Dear, GdeL; Uguccioni, DM; Dovenbarger, JA; Thalmann, ED; Hanson, E; Cudahy, EA
Abstract: BACKGROUND: The incidence of decompression illness (DCI) in recreational divers is difficult to determine because the total number of dives performed each year is not known, and must be estimated. METHODS: DAN, in conjunction with NSMRL, sent surveys to 3000 randomly selected DAN members. Some 1654 were returned and analyzed, of which 1628 contained information on diving activity and DCI for the last 5 years. The number of dives was fromlogs, memory, a combination of the two or estimated from log normal distributions fitted to cumalative frequency plots by eye. Data are given in table. (TABLE) About 75percent of responders were male accounting for 82percent of dives, the 25percent females accounted for 18percent of dives. The median for logged dives was similar for males and females but the male median was slightly higher in the other 2 catergories. Fifty-seven divers reported 67 cases of DCI (4.3percent of females, 1.06percent of dives; 3.3percent of males, 5.3percent of dives) but only 30 cases were reported as treated. The median number of dives for divers reporting DCI was similar for treated and untreated cases, ~25.2. Whether untreated cases were actually DCI is unknown, but if they aren't, DCI incidence would only be 1.51. CONCLUSION: Total DCI incidence, assuming untreated cases were DCI, is close to Bove's (3.41) for sport divers but above that for military divers (2.65) (Undersea Hyper Med 1998;25:175-178). If the survey population of DAN members is assumed to be representative of the larger population then an average of 1006 cases of DCI/year, reported to DAN from 1992-1997, at 3.38 DCI/104 dives would represent 2.98 million recreational dives/year. Whether untreated cases represent underreporting or false positives is unknown.
