Mortality in U.S. Physicians Likely to Perform Fluoroscopy-guided Interventional Procedures Compared with Psychiatrists, 1979 to 2008.

Purpose To compare total and cause-specific mortality rates between physicians likely to have performed fluoroscopy-guided interventional (FGI) procedures (referred to as FGI MDs) and psychiatrists to determine if any differences are consistent with known radiation risks. Materials and Methods Mortality risks were compared in nationwide cohorts of 45 634 FGI MDs and 64 401 psychiatrists. Cause of death was ascertained from the National Death Index. Poisson regression was used to estimate relative risks (RRs) and 95% confidence intervals (CIs) for FGI MDs versus psychiatrists, with adjustment (via stratification) for year of birth and attained age. Results During follow-up (1979-2008), 3506 FGI MDs (86 women) and 7814 psychiatrists (507 women) died. Compared with psychiatrists, FGI MDs had lower total (men: RR, 0.80 [95% CI: 0.77, 0.83]; women: RR, 0.80 [95% CI: 0.63, 1.00]) and cancer (men: RR, 0.92 [95% CI: 0.85, 0.99]; women: RR, 0.83 [95% CI: 0.58, 1.18]) mortality. Mortality because of specific types of cancer, total and specific types of circulatory diseases, and other causes were not elevated in FGI MDs compared with psychiatrists. On the basis of small numbers, leukemia mortality was elevated among male FGI MDs who graduated from medical school before 1940 (RR, 3.86; 95% CI: 1.21, 12.3). Conclusion Overall, total deaths and deaths from specific causes were not elevated in FGI MDs compared with psychiatrists. These findings require confirmation in large cohort studies with individual doses, detailed work histories, and extended follow-up of the subjects to substantially older median age at exit. © RSNA, 2017 Online supplemental material is available for this article.

Epidemiology of contemporary seroincident HIV infection in the Navy and Marine corps.

Human Immunodeficiency Virus (HIV) infection continues at a steady rate among U.S. Sailors and Marines. This study provides the first service-specific description of HIV infection demographics. All Sailors and Marines identified as HIV infected between January 2005 and August 2010 were included. The project compared personnel and epidemiologic data, and tested reposed sera in the Department of Defense Serum Repository. This group comprised 410 Sailors and 86 Marines, predominantly men. HIV infected Marines were more likely to be foreign born than their Navy counterparts, 42% versus 10%, p < 0.001. Approximately half of the patients had deployed including to the wars in Iraq or Afghanistan. Nearly half of each group was infected by the age of 25. Similar to the U.S. epidemic, Black race was over-represented. Unlike national rates, Hispanic Sailors and Marines were not over-represented. Demographics were distinct for those of specific occupational specialties. Certain ship classes carried lower incidences. Clustering of HIV infection risk occurred around deployment. The Navy and Marine Corps have different patterns of HIV infection, which may merit distinct approaches to prevention. The Navy may have unique targets for prevention efforts to include pipeline training and first assignment as well as particular occupational environments.

Controlling health care costs in the military: the case for using financial incentives to improve beneficiary personal health indicators.

OBJECTIVE: To provide insight on the feasibility and utility of implementing a broad based incentive program for health within the Military Health System (MHS). METHOD: Published studies, articles, and information on the use of financial incentives in the military setting and to promote healthy behaviors were reviewed. RESULTS: Health care costs in the MHS have more than doubled over the past decade. The high prevalence of modifiable risk behaviors such as tobacco abuse, physical inactivity and obesity and their associated chronic diseases are accounting for a significant percentage of the growth. One evidence-based approach to address this issue would be the implementation of a broad based incentive program for health whereby all MHS beneficiaries would be eligible to receive some type of financial remuneration for meeting positive personal health metrics (e.g. not smoking or a normal body mass index). This approach if designed appropriately has the potential to have a high level of acceptance within the current beneficiary population since financial incentives are already used widely in the military to help meet overall manpower requirements. CONCLUSION: The use of a MHS wide financial incentives program to instill healthy behaviors in beneficiaries' may be an effective means to curb rising healthcare cost.

Transfusion-transmissible viral infections among US military recipients of whole blood and platelets during Operation Enduring Freedom and Operation Iraqi Freedom.

BACKGROUND: Current US military clinical practice guidelines permit emergency transfusions of non-Food and Drug Administration (FDA)-compliant freshly collected blood products in theaters of war. This investigation aimed to characterize the risks of transfusion-transmitted infections (TTIs) associated with battlefield transfusions of non-FDA-compliant blood products. STUDY DESIGN AND METHODS: US Service members who received emergency transfusion products in Iraq and Afghanistan (March 1, 2002-September 30, 2007) were tested for hepatitis C virus (HCV), human immunodeficiency virus (HIV), and hepatitis B virus (HBV) infections using reposed pre- and posttransfusion sera. Selected regions of viral genomes from epidemiologically linked infected recipients and their donors were sequenced and compared. RESULTS: Of 761 US Service members who received emergency transfusion products, 475 were tested for HCV, 472 for HIV, and 469 for HBV. One transfusion-transmitted HCV infection (incidence rate of 2.1/1000 persons) was identified. The pretransfusion numbers (prevalence per 1000 persons) were HCV-four (8/1000), HIV-zero (0/1000), chronic HBV-two (4 /1000), and naturally immune (antibody to HBV core antigen)-nine (19/1000). CONCLUSION: One HCV TTI was determined to be associated with emergency blood product use. The pretransfusion HCV and HBV prevalence in transfusion recipients, themselves members of the potential donor population, indicates better characterization of the deployed force's actual donor population, and further investigations of the TTI prevalence in these donors are needed. These data will inform countermeasure development and clinical decision making.

Drowning deaths of U.S. Service personnel associated with motor vehicle accidents occurring in Operation Iraqi Freedom and Operation Enduring Freedom, 2003-2005.

OBJECTIVE: We examined common factors in vehicular drowning deaths that might lead to changes in equipment or training. METHODS: Drowning deaths among service members deployed to Operations Iraqi Freedom or Enduring Freedom, 2003 to 2005, were ascertained using the Armed Forces Medical Examiner Tracking System database. Cases were linked to Army and Navy safety and investigative files. RESULTS: Fifty-two cases of vehicular drowning deaths were identified. These occurred mostly at night, were almost always the result of a rollover, and were most frequently associated with a high-mobility medium-weight vehicle. Seat belts were rarely worn, but the majority of injuries should not have been severe enough to affect egress from the vehicle. These drowning deaths seldom occurred while engaged with the enemy and were rarely associated with bad road conditions or bad weather. CONCLUSIONS: Effective preventive strategies might focus on training and equipment to reduce rollover events and on the expeditious extrication of victims.
