Disease and nonbattle injury (DNBI) patterns were analyzed for reports from the Commander Fifth Fleet for 2000-2001 covering 217,972 person-weeks. The overall DNBI rate was 4.38 visits per 100 person-weeks with the largest subcategory being "other medical/surgical" conditions (1.36 visits/100 person-weeks and over 30% of the initial patient visits). This was followed by dermatological (0.89 visits/100 person-weeks) and respiratory conditions (0.65 visits/100 person-weeks). Collapsing total injuries would have created the third largest incidence category. The mean DNBI rate for cruisers/destroyers/ frigates (4.23 visits/100 person-weeks; SD, 2.64 visits) was not significantly different from aircraft carriers (4.76 visits/100 person-weeks; SD, 1.60, t(df = 207) = -0.91, p = 0.363) but was statistically different from supply ships (8.93 visits/100 person-weeks; SD, 2.44, t(df = 191) = -6.23, p = 0.000) and amphibious support ships (8.07 visits/100 person-weeks; SD, 3.99, t(df = 190) = -4.72, p = 0.000). These results are compared with historical data from land-based units, and the limitations in shipboard DNBI reporting are discussed. |
