The prevalence and impact of respiratory symptoms in asthmatics and nonasthmatics during deployment

OBJECTIVE: The purpose of this study was to compare the prevalence, severity, and impact of respiratory symptoms in asthmatics and nonasthmatics during Operation Enduring Freedom and Operation Iraqi Freedom. METHODS: A survey was given to 1,250 active duty soldiers and Department of Defense contractors returning from Operation Enduring Freedom/Operation Iraqi Freedom. Subjects were asked about demographics, smoking habits, respiratory symptoms, and impact on job performance before and during deployment. Patients with a history of asthma were asked method of diagnosis, current symptoms, and asthma therapy. RESULTS: A total of 1,193 subjects returned the completed questionnaire (95% response rate). Mean age of respondents was 38 +/- 11 years, 83% (n = 977) were male, and 31% (n = 375) were past or present smokers. Sixty-one subjects (5%) reported a previous diagnosis of asthma. Both asthmatics and nonasthmatics had increased respiratory symptoms of wheezing, cough, sputum production, chest pain/tightness, and allergy symptoms during deployment compared to predeployment (p < 0.05 for all). When compared to nonasthmatics, asthmatic subjects reported more wheezing, sputum production, and chest pain/tightness during deployment (p < 0.0001, 0.05, 0.05 respectively), had more difficulty with military duties (p < 0.05), and were more likely to seek medical attention and receive duty restrictions (p < 0.0001). Twenty-six percent (n = 16) of asthmatics reported poor baseline symptom control, and this group had significantly increased symptoms, functional limitations, and health care utilization when compared to asthmatics who were symptom-controlled at baseline. CONCLUSIONS: Respiratory symptoms were common among both asthmatics and nonasthmatics during deployment. Differences in symptoms and health care utilization in this group of asthmatics were primarily due to subjects with poor baseline control.     

Problems with veteran-family communication during operation enduring freedom/operation Iraqi freedom military deployment

Twenty Reserve component (Army and Marines) and Army National Guard male veterans of Operational Enduring Freedom/Operation Iraqi Freedom discuss their deployment and postdeployment family reintegration experiences. A Grounded Theory approach is used to highlight some of the ways in which family miscommunication during deployment can occur. Communication with civilian family members is affected by the needs of operational security, technical problems with communication tools, miscommunication between family members, or because veterans have "nothing new to say" to family back home. These communication difficulties may lead to an initial gulf of understanding between veterans and family members that can cause family strain during postdeployment family reintegration. We end with a discussion of veteran family reintegration difficulties.     

Process of care for battle casualties at Walter Reed Army Medical Center: Part II. Physical therapy service

Physical therapists, physical therapy assistants, and physical therapy technicians provide care to soldiers, sailors, Marines, and airmen returning from Operation Enduring Freedom and Operation Iraqi Freedom. We describe the inpatient and outpatient services provided, the problems and solutions encountered, and the lessons learned at the beginning of the war.     

Inpatient hospitalizations of U.S. military personnel medically evacuated from Iraq and Afghanistan with combat-related traumatic brain injury

Traumatic brain injury (TBI) has been called the signature wound of Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF). The aim of the present study was to describe and assess the incidence of inpatient hospitalizations of U.S. military personnel who were medically evacuated from OIF and OEF with combat-related TBI. Inpatient medical records from 2003 to 2008 were used to determine incident episodes of TBI requiring hospitalization in Landstuhl or CONUS Regional Medical Centers. Denominator data for calculating incidence rates were available from the Defense Manpower Data Center. During the study period, 1,213 U.S. military personnel from OIF and OEF were hospitalized with combat-related TBI. Of these, the largest proportion (40.9%) occurred in 2007. The rate of inpatient hospitalization with TBI was 10.4 per 10,000 troop strength (95% confidence interval: 9.9, 10.9). Future research should examine the incidence of TBI in-theater and include an analysis by injury severity.     

The U.S. Navy's forward resuscitative surgery system during Operation Iraqi Freedom

The forward resuscitative surgery system (FRSS) is the Navy's most forward-deployed echelon II medical unit. Between March and August 2003, six FRSS teams were deployed in support of Operation Iraqi Freedom (OIF). During the combat phase of OIF (March 21 to May 1, 2003), a total of 34 Marine Corps and 62 Iraqi patients underwent treatment at a FRSS. FRSS teams were assigned two distinct missions; "forward" FRSS teams operated with combat service support elements in direct support of regimental combat teams, and "jump" FRSS teams served as a forward element of a surgical company. This article presents the experiences of the FRSS teams in OIF, including a discussion of time to presentation from wounding, time to operation, time to evacuation, and lessons learned from the deployment of the FRSS.     

Deployment experiences of Army nurse practitioners

Army Nurse Practitioners (NPs) provide immediate and lifesaving care during combat operations. The most recent conflicts of Operation Iraqi Freedom and Operation Enduring Freedom have seen an increasing number of NP deployments. The uniqueness of these conflicts has also seen NPs being used in nontraditional roles. This study surveyed 50 Army NPs with deployment experience to explore and elucidate their clinical practices in a combat environment. Over 70% reported seeing greater than 11 patients a day with the top three diagnoses of musculoskeletal/soft tissue (noncombat), spinal pain (mechanical, sciatica), and gastrointestinal complaints. Over 74% reported having a physician available for collaboration, but 50% reported providing independent emergency care and 58% treating life-threatening injuries. The NPs in this study report standard credentialing privileges with most care falling within this realm. However, a few report nontraditional roles such as hospital admitting privileges. This study adds to the growing body of knowledge on NP practice in a combat environment, which shows increased decision making and advanced clinical skills. NPs are battlefield multipliers who bring additional skills and abilities to the combat environment.     

Combat casualty care: the Alpha Surgical Company experience during Operation Iraqi Freedom

BACKGROUND: Operation Iraqi Freedom was the first large-scale combat operation involving the U.S. Marine Corps since the Persian Gulf War in 1991. Data from a combat surgical company are presented. METHODS: Records of all U.S. and Iraqi combat casualties admitted to the surgical company were reviewed. RESULTS: Fifty-three (57%) of 93 patients suffered penetrating injuries. Most wounds were produced by high-explosive munitions (mines, hand grenades, and rocket-propelled grenades), and the majority (51%) of wounds were to the extremities. The time to surgical care averaged 4.7 hours (range, 1.5-48 hours), and 98% of the patients seen at our facility survived. CONCLUSIONS: The time from injury to surgical care was considered long by civilian standards; however, this did not appear to affect outcomes substantially. A small percentage (5.2%) of injuries were to the torso. Hypothermia was commonly present. Because of the nature of their wounds, all patients required additional surgery after evacuation to rear area facilities. The outcomes of individual patients are not known, although it is known that only one Marine died after reaching medical care and, to date, no Marines have subsequently died of their wounds.     

Deployment risk factors and postdeployment health profiles associated with traumatic brain injury in heavy drinking veterans

Along with post-traumatic stress disorder (PTSD), mild traumatic brain injury (mTBI) is considered one of the "signature wounds" of combat operations in Iraq (Operation Iraqi Freedom [OIF]) and Afghanistan (Operation Enduring Freedom [OEF]), but the role of mTBI in the clinical profiles of Veterans with other comorbid forms of post-deployment psychopathology is poorly understood. The current study explored the deployment risk and postdeployment health profiles of heavy drinking OIF and OEF Veterans as a function of mTBI. Sixty-nine heavy-drinking OIF/OEF Veterans were recruited through a Veterans' Affairs Medical Center and completed questionnaires and structured interviews assessing war-zone experiences, postdeployment drinking patterns, and PTSD symptoms. Veterans with positive mTBI screens and confirmed mTBI diagnoses endorsed higher rates of combat experiences, including direct and indirect killing, and met criteria for PTSD at a higher rate than Veterans without a history of mTBI. Both PTSD and combat experiences independently predicted screening positive for mTBI, whereas only combat experiences predicted receiving a confirmed mTBI diagnosis. mTBI was not associated with any dimension of alcohol use. These results support a growing body of literature linking mTBI with PTSD.     

Acupuncture: a useful tool for health care in an operational medicine environment

Acupuncture is a form of medical care that originated in China; it has evolved and progressed over thousands of years to become one of the most commonly used forms of health care throughout the world. Allopathic (Western) medicine has begun to seriously investigate and to use this system only in the past three decades. Although acupuncture's mechanisms for healing are not fully understood, it helps many conditions. Using acupuncture reduces or eliminates the need for expensive medications and the potential risk of adverse events resulting from medications, with cost savings and health benefits to patients. During a deployment of naval combat engineers to Iraq in support of Operation Iraqi Freedom, acupuncture was used in the health care of sailors, Marines, and soldiers. It objectively and subjectively improved the health of troops in the field. Troops were able to function while being treated, reducing or avoiding sick in quarters or light limited duty status and saving operational man-days. Acupuncture in the right hands can serve as a health force multiplier (amplifying a provider's clinical impact) and can be integrated into routine health care, whether in garrison or in the field.     

Anesthesia services aboard USNS COMFORT (T-AH-20) during Operation Iraqi Freedom

USNS COMFORT (T-AH-20), the only U.S. hospital ship to be deployed in support of combat operations during Operation Iraqi Freedom, sailed from Baltimore, Maryland, on January 6, 2003, and returned on June 12, 2003. During the course of her deployment, 648 anesthetic procedures were performed. We describe the anesthesia services provided, lessons learned, and recommendations for future concepts of employment.     

A review of 41 upper extremity war injuries and the protective gear worn during Operation Enduring Freedom and Operation Iraqi Freedom

Forty-one patients with upper extremity war injuries sustained during combat operations Operation Enduring Freedom and Operation Iraqi Freedom were reviewed to report on protective gear availability and usage at the time of injury. Participants treated at the Madigan Army Medical Center occupational therapy clinic from August 2004 until February 2005 completed a questionnaire regarding injuries sustained during deployment. Overall, 6 injuries were to upper extremity regions that were covered with issued protective gear; 21 injuries were to areas not covered with issued protective gear (i.e., participant was not wearing issued gear), and 22 injuries were to regions that were not covered because no protective gear was issued for that body area. Although this study is limited, future research would provide valuable insights about the efficacy of current body armor and the need for additional or modified gear.     

Injury and illness casualty distributions among U.S. Army and Marine Corps personnel during Operation Iraqi Freedom

The objective of this study was to evaluate the distributions of U.S. Marine Corps and Army wounded in action (WIA) and disease and nonbattle injury (DNBI) casualties during Operation Iraqi Freedom Major Combat Phase (OIF-1) and Support and Stability Phase (OIF-2). A retrospective review of hospitalization data was conducted. chi2 tests were used to assess the Primary International Classification of Diseases, 9th Revision (ICD-9), diagnostic category distributions by phase of operation, casualty type, and gender. Of the 13,071 casualties identified for analysis, 3,263 were WIA and 9,808 were DNBI. Overall, the proportion of WIA was higher during OIF-1 (36.6%) than OIF-2 (23.6%). Marines had a higher proportion of WIA and nonbattle injuries than soldiers. Although overall DNBI distributions for men and women were statistically different, their distributions of types of nonbattle injuries were similar. Identifying differences in injury and illness distributions by characteristics of the casualty population is necessary for military medical readiness planning.     

Wounding patterns for U.S. Marines and sailors during Operation Iraqi Freedom, major combat phase

This investigation examined the wounds incurred by 279 U.S. Navy-Marine personnel (97% Marines and 3% sailors) identified as wounded in action during Operation Iraqi Freedom, from March 23 through April 30, 2003. The goal was to assess the potential impact of each causative agent by comparing the differences in anatomical locations, types of injuries caused, and medical specialists needed to treat the casualties. The overall average number of diagnoses per patient was 2.2, and the overall average number of anatomical locations was 1.6. The causative agents were classified into six major categories, i.e., small arms, explosive munitions, motor vehicle accidents, falls, weaponry accidents, and other/unknown. Explosive munitions and small arms accounted for approximately three of four combat-related injuries. Upper and lower extremities accounted for approximately 70% of all injuries, a percentage consistent for battlefield injuries since World War II.     

U.S. Army disease and nonbattle injury model, refined in Afghanistan and Iraq

Previous analysis of Operation Desert Shield/Operation Desert Storm data yielded a disease and nonbattle injury (DNBI) model using distinct 95th percentile daily admission rates during the three phases of a war-fighting operation to predict medical requirements. This study refines the model with data from Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF). Inpatient health care records of U.S. Army soldiers deployed to OEF and OIF who were admitted with DNBI diagnoses were analyzed. DNBI admission rates for OEF and OIF were compared with rates for Operation Desert Shield/Operation Desert Storm. DNBI admission rates for OEF and OIF were lower than those for Operation Desert Shield/Operation Desert Storm. Rates among the phases of OIF were distinctly different. DNBI admission rates have been reduced during recent deployments. The concepts of the original model based on Operation Desert Shield/Operation Desert Storm data were validated by experiences during OEF and OIF. Continuous surveillance of DNBI admission rates is recommended.     

What was different about exposures reported by male Australian Gulf War veterans for the 1991 Persian Gulf War, compared with exposures reported for other deployments?

This study identified chemical and environmental exposures specifically associated with the 1991 Persian Gulf War. Exposures were self-reported in a postal questionnaire, in the period of 2000-2002, by 1,424 Australian male Persian Gulf War veterans in relation to their 1991 Persian Gulf War deployment and by 625 Persian Gulf War veterans and 514 members of a military comparison group in relation to other active deployments. Six of 28 investigated exposures were experienced more frequently during the Persian Gulf War than during other deployments; these were exposure to smoke (odds ratio [OR], 4.4; 95% confidence interval, 3.0-6.6), exposure to dust (OR, 3.7; 95% confidence interval, 2.6-5.3), exposure to chemical warfare agents (OR, 3.9; 95% confidence interval, 2.1-7.9), use of respiratory protective equipment (OR, 13.6; 95% confidence interval, 7.6-26.8), use of nuclear, chemical, and biological protective suits (OR, 8.9; 95% confidence interval, 5.4-15.4), and entering/inspecting enemy equipment (OR, 3.1; 95% confidence interval, 2.1-4.8). Other chemical and environmental exposures were not specific to the Persian Gulf War deployment but were also reported in relation to other deployments. The number of exposures reported was related to service type and number of deployments but not to age or rank.     

Descriptive summary of patients seen at the surgical companies during Operation Iraqi Freedom-1

The Navy-Marine Corps Combat Trauma Registry is a data repository summarizing information from data sets describing injuries sustained and treatments administered to casualties from the point of injury to rehabilitation. Among the medical facilities contributing data to the Combat Trauma Registry during Operation Iraqi Freedom were the Marine Corps forward surgical companies. The surgical companies offer resuscitative surgery, medical treatment, and temporary holding facilities, in addition to preparing patients for evacuation. This article reviews the types of patients admitted and treatments provided at the surgical companies during the major combat period of Operation Iraqi Freedom. The surgical companies saw an average of 15 to 17 patients per day during this period. Less than 20% of the U.S. casualties seen were wounded in action. In contrast, >75% of the enemy prisoner of war presentations were for battle injuries. Less than 15% of the patients were held at the facilities for >24 hours.     

Advising and assisting an Iraqi Army medical clinic: observations of a U.S. military support mission

Medical civil-military operations are important for deployed military medical units engaged in counter-insurgency missions. There are few reports on military support for a host nation's military medical infrastructure, and we describe an initiative of the 21st Combat Support Hospital in 2010 during the postsurge phase of Operation Iraqi Freedom and Operation New Dawn. The goal was to incrementally improve the quality of care provided by Iraqi 7th Army medical personnel using existing clinic infrastructure and a low budget. Direct bedside teaching to include screening and treatment of ambulatory patients (sick call), focused pharmacy and medical supply system support, medical records documentation, and basic infection control compliance were the objectives. Lessons learned include the requirement to implement culturally relevant changes, maintain focus on system processes, and maximize education and mentorship through multiple modalities. In summary, a combat hospital can successfully implement an advise and assist mission with minimal external resources.     

Magnetic resonance imaging abnormalities in symptomatic and contralateral knees: prevalence and associations with traumatic history in general practice

BACKGROUND: After trauma, internal knee lesions are found in approximately two thirds of patients. However, magnetic resonance imaging abnormalities have also been described in asymptomatic volunteers. HYPOTHESIS: Not all visualized lesions in symptomatic posttraumatic knees are the result of recent trauma; there are subgroups of lesions that may be preexistent. STUDY DESIGN: Cross-sectional study (prevalence); Level of evidence, 2. METHODS: Patients visiting their general practitioners after knee trauma were invited for magnetic resonance imaging of both knees. Prevalence of knee abnormalities was compared between symptomatic and asymptomatic knees. Multivariable analysis was performed to investigate the association between lesions that were seen in symptomatic and asymptomatic knees (ie, effusion and meniscal tears) and recent trauma, history of old trauma, age, and osteoarthritis. RESULTS: In 134 participants, ligament lesions were found almost exclusively in symptomatic knees. Meniscal lesions and effusion were almost equally found in symptomatic and asymptomatic knees. Effusion was related to recent trauma (odds ratio, 14.0; 95% confidence interval, 5.0-39.6) and osteoarthritis (odds ratio, 4.7; 95% confidence interval, 1.4-15.5) but not to history of old trauma and age. Meniscal tears were more common in older patients (odds ratio, 1.09; 95% confidence interval, 1.05-1.12) but were not related to osteoarthritis. History of old trauma was more strongly related to the group of radial, longitudinal, and complex meniscal tears (odds ratio, 8.6; 95% confidence interval, 3.3-22.5) than to horizontal tears (odds ratio, 2.3; 95% confidence interval, 0.9-5.6). Recent trauma was not related to horizontal meniscal tears but was strongly related to other types of meniscal tears (odds ratio, 3.2; 95% confidence interval, 1.4-6.9). CONCLUSION: Ligament knee lesions are most probably the result of recent trauma. Radial, longitudinal, and complex meniscal tears are strongly related to trauma, whereas horizontal meniscal tears and effusion may be preexistent in many cases.     

Challenges to military working dog management and care in the Kuwait theater of operation

In a combat environment, troop safety and installation security are paramount. Documentation of the frequent use of explosive devices by insurgents in Southwest Asia has increased the need for augmentation of defensive capabilities. Military working dogs (MWDs) are trained and certified to perform missions supporting security and detection of explosives. Challenges arise in theater because the number of certified dogs available can be limited and the standards of housing and care that are available in the continental United States are not usually available in a combat theater. Planning, preparation, and training of MWD handlers,animal care specialists, and Veterinary Corps officers will maximize mission performance and MWD health. Some of th echallenges and needs associated with management and care of the MWDs in the Kuwait theater of operation are discussed. Suggested improvements to the current deployment readiness paradigm are offered from the perspective of a staff veterinarian who was deployed in support of Operation Iraqi Freedom in 2004.
