FDG20100017H Incidence of Venous Thomboembolism 9VTE) and Effect of Thrombosis Prophylaxis Guidelines in Patients Transported Aeromedically.

Abstract : Initial data on patients with existing VTE was received from USTRANSCOM in 2010, but did not include data on the other patients. This was addressed by granting the PI permission to use TRAC2ES. Eventually, the TRAC2ES data was received via secure website. With an approved TMA DSA in place (approved 23 Jan 2013), the M2 data was extracted and compiled by the Knowledge Center. In the process, it was learned that the M2 data prior to year 2007 was not accessible and the TRACES data only included years 2002- 2009. All data was stored on an approved external drive. The two data sets (M2 and TRACES) for the years 2007, 2008 and 2009 were merged successfully. Merger was done with SSN, FMP, and DOB. Based on the analysis, the main finding is that the U.S. military personnel (including active duty, guard and reserve members) age 25-31 that were transported aeromedically during 2007-2009 were at higher risk for developing a VTE than members age 18-21, keeping rank and sex constant. In conclusion, this study did not meet the proposed objectives. The analysis of the merged data revealed duplicate records (mostly in M2 data set) or missing information (mostly in TRACES data base). This posed difficulty in performing an efficacious analysis and providing answers to study questions.
