Non-battle injury casualties during the Persian Gulf War and other deployments.

OBJECTIVE: To review injury occurrence and to evaluate various injury surveillance systems used on recent deployments of U.S. military personnel. BACKGROUND: Injuries that occur in a deployed military force are more likely to have an immediate and detrimental effect on the military mission than those in garrison or training. These injuries have a direct impact on deployed personnel and unit readiness and consume limited field medical resources. METHODS: Data collected during four recent deployments were evaluated. Administrative databases established for the routine collection of death and hospital admissions were used to characterize mortality and morbidity in the Persian Gulf War. Surveillance teams deployed to Haiti, Somalia, and Egypt provided inpatient and outpatient data for those missions. RESULTS: Data collected by these surveillance systems are presented. Unintentional trauma accounted for 81% of deaths during the Persian Gulf War and 25% of hospital admissions. During operations in Somalia and Haiti, 2.5% to 3.5% of about 20,000 troops in each deployment sought medical treatment for an injury or orthopedic problem each week. In Egypt, injuries accounted for about 25% of all outpatient visits to medical treatment facilities. CONCLUSIONS: Injuries were the leading cause of death and a leading cause of morbidity during recent deployments of U.S. troops. Comprehensive injury surveillance systems are needed during deployments to provide complete and accurate information to commanders responsible for the safety of the force. Recommendations for establishing such systems are made in this article.

The effects of inadvertent exposure of mefloquine chemoprophylaxis on pregnancy outcomes and infants of US Army servicewomen.

During US military operations in Somalia, mefloquine, a drug for malaria chemoprophylaxis, was not approved for use in pregnant women. Some female soldiers inadvertently used mefloquine before becoming aware of their pregnancy. A registry was established to follow the outcomes of these pregnancies. Questionnaires were administered at the time the pregnancy was diagnosed, after termination or delivery, and at 1 year after birth. Seventy-two soldiers were eligible for the registry. There were 17 elective abortions, 12 spontaneous abortions, 1 molar pregnancy, and 23 live births. The outcome for 19 soldiers was unknown. An unexpected high rate of spontaneous abortions was observed. All infants were healthy at birth, with no major congenital malformations. One infant died at 4 months of viral pneumonitis. At 1 year of age, 13 infants were reported to be healthy, with normal cognitive and motor development. This study provides additional postmarketing data that mefloquine does not cause gross congenital malformations.

Comparative mortality among US military personnel in the Persian Gulf region and worldwide during Operations Desert Shield and Desert Storm.

OBJECTIVE: To determine cause-specific mortality rates among US troops stationed in the Persian Gulf region and compare them with those of US troops serving elsewhere during Operations Desert Shield and Desert Storm. DESIGN: Retrospective cohort. POPULATION: US men and women on active duty from August 1, 1990, through July 31, 1991. MAIN OUTCOME MEASURES: Deaths occurring among all active-duty US military persons during the 1-year study period. Age-adjusted mortality rates among US troops stationed in the Persian Gulf region were compared with rates projected from mortality rates among troops on active duty elsewhere. RESULTS: A total of 1769 active-duty persons died during the study period, 372 in the Persian Gulf region and 1397 elsewhere. Of the 372 deaths in the Persian Gulf region, 147 (39.5%) occurred as a direct result of combat during the war, 194 (52.2%) resulted from injuries not incurred in battle, and 30 (8%) resulted from illness. Twenty-three of the deaths due to illness were considered unexpected or cardiovascular deaths. Based on age-adjusted mortality rates observed among US troops on active duty outside the Persian Gulf region, 165 deaths from unintentional injury and 32 deaths from illness (20 of which were unexpected or cardiovascular) would have been anticipated among Persian Gulf troops. CONCLUSION: Except for deaths from unintentional injury, US troops in the Persian Gulf region did not experience significantly higher mortality rates than US troops serving elsewhere. There were no clusters of unexplained deaths. The number and circumstances of nonbattle deaths among Persian Gulf troops were typical for the US military population.

Childhood injury mortality in Ohio, 1979 to 1986. Setting priorities for prevention.

Injury deaths in Ohio children aged 1 to 16 years account for less than 0.5% of all deaths in the state but 6% of all years of life lost before age 65 years. In this study, injury mortality rates were calculated by sex for three age groups (1 to 5, 6 to 11, and 12 to 16 years) and three population groups (metropolitan white, metropolitan nonwhite, and nonmetropolitan). The 15 metropolitan counties were those with a central city of at least a population of 50,000, containing 60% of the state's population. Fire is the leading cause of injury mortality for metropolitan children aged 1 to 5 years, while motor vehicle injuries and drowning are the leading causes for nonmetropolitan children in this age group. Fire is also the leading cause for metropolitan nonwhite children aged 6 to 11 years, while motor vehicle injuries are the leading cause for nonmetropolitan children, and pedestrian injuries are the leading cause for metropolitan white children. For nonmetropolitan and metropolitan white children aged 12 to 16 years, motor vehicle injuries are the leading cause, while for metropolitan nonwhite children homicide is the leading cause. Excess deaths for each cause were estimated by calculating the number of deaths expected for each age group if the rate experienced by the second-lowest population race group had applied to the whole population in that age group, and comparing this with the observed number. Using this approach, highest priority would be placed on prevention of motor vehicle deaths in 12- to 16-year-old nonmetropolitan and metropolitan white children, of fire deaths in metropolitan nonwhite children aged 1 to 11 years, and of drowning deaths in boys aged 12 to 16 years in all three population groups.
