Section 3 - Dive InjuriesFigure 3.7-6 describes the outcome at discharge when the cases arestratified by DAN’s Perceived Severity Index (page 48). There is littledifference among the categories in the degree of residual symptomsat discharge, unlike previous years, when persistence of residualsymptoms after treatment was related to the severity of symptomsat presentation.Figure 3.7-6Outcomesat dischargeby PerceivedSeverity Index(n=293).The number of recompression treatments given divers varied extensively.The majority of divers (55 percent of our sample) receivedonly one recompression treatment; however, some divers receivedup to 13 treatments. Figure 3.7-7 shows this distribution.Figure 3.7-7Total numberof recompressionsfor injured divers(n=294).DAN’s <strong>Report</strong> on Decompression Illness, Diving Fatalities and Project Dive Exploration: 2005 Edition 63
Section 3 - Dive InjuriesThe majority of divers were treated in multiplace chambers. Figure3.7-8 shows this distribution.Figure 3.7-8Type of chamberin which injureddivers were treated(n=297).3.8 Data Collection IssuesThis is the last year that DAN’s diving report will present data collectedusing only the DIRF. During the years 2004 and 2005, thetransition to the new Scuba Epidemiological <strong>Report</strong>ing Form (SERF)will occur. Using the SERF should result in an improvement in boththe response rate and the quality of the data reported.The SERF was designed to specifically answer the question of howthe severity of an injured diver’s symptoms at the time of presentationto a medical facility correlates with the eventual medical outcome.To accomplish this goal, the SERF strictly stratifies all cases byseverity at the time of presentation. Since the issue of delayed treatmentand the effect of time on long-term outcome are still unknown,the condition and evolution of symptoms at multiple time points isalso recorded. Because the issue of diagnostic ambiguity is important,the SERF allows the treating physician to state his or herdegree of confidence in the diagnosis.Finally, the SERF is integrated with PDE technology to facilitate thecapture of dive profile information from the injured diver’s divecomputer. This will allow precise documentation of the pressuretimeexposure associated with the specific injury. All of these innovationswill be of great assistance in answering questions regardingthe risks of decompression illness in recreational diving.64DAN’s <strong>Report</strong> on Decompression Illness, Diving Fatalities and Project Dive Exploration: 2005 Edition
