Public health systems are stressed by increasing demands and inadequate resources. This study was designed to demonstrate how economic impact analysis can estimate the economic value of a local public health system's infrastructure as well as the economic assets of an "Academic Health Department" model. This study involved the secondary analysis of publicly available data on health department finances and employment using proprietary software specifically designed to assess economic impacts. The health department's impact on the local community was estimated at over 100 million dollars, exceeding the economic impact of other recently studied local industries with no additional costs to local taxpayers.

We provide a descriptive epidemiological analysis of needlestick injuries in Navy medical personnel from the Naval Safety Center database (INJTRAK) for a 1-year period (October 2001 through September 2002). The reports of needle sticks were reviewed on the basis of the Bureau of Labor Statistics Occupational Injury and Illness Classification system for exposure code 3431 (N = 265). Most of the reported needle sticks occurred in men (60.8%) and were from personnel <30 years of age (73.8%). Hospital corpsmen represented the most common work group (57%). Fingers were the most commonly reported anatomical location (77%) for needle sticks. The information suggests several focus areas for reducing needle-stick injuries and improving training. The analysis also reinforces the importance of timely and accurate reporting of injuries related to medical apparatus to the Naval Safety Center.

We examined tuberculosis skin conversion rates for U.S. Navy and Marine Corps personnel for 1999 to 2002, using information submitted to the Navy Environmental Health Center (Portsmouth, Virginia). The screening of 1,190,866 Navy and Marine Corps personnel with tuberculosis skin testing found 17,439 (1.46%) new reactors. The annual conversion rate increased from 1.35% in 1999 to 1.33% in 2000, 1.54% in 2001, and 1.61% in 2003 [chi2 for trend (df = 1) = 102.368; p = 0.000]. The overall conversion rate for aircraft carriers was 0.52%, with significantly higher rates for amphibious ships (1.76%; relative risk, 3.33; 95% confidence interval, 2.98-3.71; p = 0.000) and Marine units (1.13%; relative risk, 2.17; 95% confidence interval, 1.98-2.38; p = 0.000). Annual conversion rates increased significantly over the period for aircraft carriers [chi2 for trend (df = 1) = 4.950; p = 0.02608] and decreased significantly for amphibious ships [chi2 for trend (df = 1) = 40.197; p = 0.000]. Conversion rates were consistent with the recent historical values for the Navy and Marine Corps.

We analyzed weekly disease nonbattle injury data from the Joint Task Force in Haiti during 2004. Surveillance found 908 initial visits during 17,938 person-weeks, for an overall rate of 5.1% (95% confidence interval, 4.7-5.4%), above the reference rate of 4% suggested by the Chairman of the Joint Chiefs of Staff. Rates of dermatological (1%), respiratory (0.8%), and other medical/surgical (0.9%) conditions were above suggested rates, whereas rates of work injuries (0.6%) and recreational injuries (0.8%) were below suggested rates. Leading causes of light duty (n = 1,079; 6.01 days per 100 person-weeks) were recreational injuries (39%) and work-related injuries (36%), followed by other medical/surgical conditions (12%). One case of malaria was reported during the deployment. These rates are lower than disease nonbattle injury rates of 9.2% to 13% reported for multinational forces from previous operations in Haiti. They are also lower than rates of 7.1% to 8.1% reported from Bosnia and Kosovo in the late 1990s.
