Title: [abstract] OLDER DIVERS AND OUTCOMES AFTER THE TREATMENT OF DECOMPRESSION ILLNESS
Author: Dear, GdeL; Freiberger, JJ; DeNoble, PJ; Uguccioni, DM; Moon, RE; Vann, RD
Abstract: BACKGROUND: It has been suggested that older divers have worse outcomes after the treatment of decompression illness (DCI). We present here a retrospective study of the effect of age on outcome after DCI in recreational diver MATERIALS and METHODS: All cases of DCI in the DAN database from 1998-2003 (approx.400 analyzed per year) were included. Residual symptoms at the end of the hyperbaric therapy were recorded as complete relief (CR), partial resolution or no change. An older diver (OD) was defined as age = 50 years, younger (YD) as less than 50 years. The severity of presenting symptoms was defined using the Perceived Severity Index (PSI, see DAN Report on Decompression Illness, Diving Fatalities and Project Dive Exploration, 2002) into Severe Neurological (SerN) and Mild Neurological (MildN) symptoms, Cardiopulmonary (CP), Pain Only, Skin and Other Categories (Other). The relative frequency of different presentations was examined. No attempt was made to determine the cause of DCS as limited exposure records were available RESULTS: There were 2867 records, 398 in older divers. Statistical differences between groups were analyzed by chi square. Significantly more OD had SerN, 35.93percent than YD, 27.21percent. This ratio was reversed, but not significantly for all other presentations. In OD complete relief was significantly less likely for those suffering from SerN and MildN than in YD, shown in the table below. <INSERT TABLE FROM PICTURE> SUMMARY: Older divers who experience DCI have more serious symptoms and signs and their outcome is worse. Older divers should be cautioned to expect these outcomes if they should develop symptoms of DCI. 1 Smerz RW, UHM 2004
