Postinjury Care and Complications Among U.S. Military Women With Combat-Related Major Limb Traumatic Amputation.

BACKGROUND: U.S. servicewomen may be at greater risk of injury in future conflicts as they integrate into combat occupations. More than 1,000 servicewomen were wounded during military conflicts in Iraq and Afghanistan. Some women sustained traumatic amputations, and research on their postinjury health is needed. OBJECTIVE: To describe acute care, complications, and health care utilization among servicewomen with combat-related amputations, comparing them with injured men. METHODS: In this retrospective matched-pairs study, women were identified from the Expeditionary Medical Encounter Database between 2003 and 2012 and matched with men on amputation injuries, injury severity, and age. Differences were assessed with nonparametric tests for paired data. RESULTS: Of 20 women identified for analysis, 13 received tourniquets, three were administered procoagulants, and six had massive transfusions. Women averaged 3.4 (SD = 1.6) postinjury complications, and the most frequent were heterotopic ossification (n = 17), posthemorrhagic anemias (n = 13), and bacterial wound infections (n = 10). Acute care and complications were similar among men. Women averaged more acute care days (M = 49.8, SD = 30.6) than men (M = 46.1, SD = 27.4) but fewer intensive care unit days (women: M = 2.6, SD = 4.0; men: M = 4.4, SD = 8.3). No statistical differences were observed. CONCLUSION: Postinjury care among servicewomen with combat-related amputations was comparable with servicemen, and complications were common. This information can aid providers and nursing staff in the management of these injuries.

Serious Inhalation Injuries From Military Operations in Afghanistan, Iraq, and Syria.

OBJECTIVE: To characterize serious inhalation injuries seen during recent military operations, and assess whether bronchoscopic severity findings were associated with clinical presentation and outcomes. METHODS: Service members who suffered inhalation injuries while deployed to Iraq, Afghanistan, or Syria from 2001-2018 were identified using ICD-9 and 10 codes from the Expeditionary Medical Encounter Database (EMED), which is abstracted from patient records in forward-deployed medical facilities. Further information including demographics, mechanism of injury, mortality, total burn surface area (TBSA), degree of facial burn, total Injury Severity Score (ISS), and first post-injury bronchoscopy notes were collected. Patients were excluded with ISS less than 16 or without sufficient details regarding bronchoscopy. Injuries were grouped based on bronchoscopic Abbreviated Injury Scores (AIS) into low-grade (AIS of 1), moderate-grade (AIS of 2), or high-grade (AIS of 3 or 4). RESULTS: 91 patients met inclusion criteria, with no significant differences in age, gender, paygrade, or service branch between degrees of injury. There were no statistical correlations between grade of injury and battle versus non-battle injury, blast versus non-blast mechanism, TBSA, or degree of facial burn. High-grade injuries had significantly higher ISS than low or moderate-grade injuries. After adjusting for ISS, the odds ratio of death was 10.4 (95% CI 1.47 to 74.53) for those with high-grade and 3.7 (95% CI 0.45 to 32.30) for those with moderate-grade compared to low-grade injuries. CONCLUSION: In this cohort of deployed military members with inhalation injuries, initial bronchoscopic severity findings are strongly associated with mortality even after adjusting for ISS. The AIS may be an important prognostic tool in all of those with serious inhalation injuries.

Validity and Reliability of a New Measure of Nursing Experience With Unintended Consequences of Electronic Health Records.

Unintended consequences of electronic health records represent undesired effects on individuals or systems, which may contradict initial goals and impact patient care. The purpose of this study was to determine the extent to which a new quantitative measure called the Carrington-Gephart Unintended Consequences of Electronic Health Record Questionnaire (CG-UCE-Q) was valid and reliable. Then, it was used to describe acute care nurses' experience with unintended consequences of electronic health records and relate them to the professional practice environment. Acceptable content validity was achieved for two rounds of surveys with nursing informatics experts (n = 5). Then, acute care nurses (n = 144) were recruited locally and nationally to complete the survey and describe the frequency with which they encounter unintended consequences in daily work. Principal component analysis with oblique rotation was applied to evaluate construct validity. Correlational analysis with measures of the professional practice environment and workarounds was used to evaluate convergent validity. Test-retest reliability was measured in the local sample (N = 68). Explanation for 63% of the variance across six subscales (patient safety, system design, workload issues, workarounds, technology barriers, and sociotechnical impact) supported construct validity. Relationships were significant between subscales for electronic health record-related threats to patient safety and low autonomy/leadership (P < .01), poor communication about patients (P < .01), and low control over practice (P < .01). The most frequent sources of unintended consequences were increased workload, interruptions that shifted tasks from the computer, altered workflow, and the need to duplicate data entry. Convergent validity of the CG-UCE-Q was moderately supported with both the context and processes of workarounds with strong relationships identified for when nurses perceived a block and altered process to work around it to subscales in the CG-UCE-Q for electronic health record system design (P < .01) and technological barriers (P < .01).

Sex Differences in Screening Positive for Post-Traumatic Stress Disorder After Combat Injury.

INTRODUCTION: U.S. military women were at risk of combat exposure and injury from asymmetric warfare during the conflicts in Iraq and Afghanistan. Previous research has yielded mixed results when examining sex differences in PTSD following operational deployment. To date, no study has explored sex differences in PTSD after combat injury. MATERIALS AND METHODS: This retrospective study included U.S. military service men and women who experienced a combat injury in Iraq or Afghanistan (March 2003 to March 2013) and completed a Post-Deployment Health Assessment (PDHA) within 1 year of injury. The PDHA is administered at the end of deployment and includes the 4-item Primary Care PTSD Screen. The prevalence of screening positive for PTSD was evaluated by sex using a chi-square test. Multivariable logistic regression was used to assess the association between sex and PTSD while adjusting for covariates. RESULTS: The study sample included 16,215 injured military personnel (666 women and 15,549 men). The average time between injury and PDHA was 132 days (SD = 91.0). Overall, women had a higher prevalence of screening positive for PTSD than men (48.3% vs. 40.9%, P < .001). In multivariable regression, women had higher odds than men of screening positive for PTSD (odds ratio, 1.34; 95% confidence interval, 1.14-1.57). Psychiatric history was the strongest predictor of screening positive for PTSD regardless of sex (odds ratio, 1.59; 95% confidence interval, 1.45-1.74). CONCLUSIONS: In this novel study of military service members, women were more likely to screen positive for PTSD than men after combat injury. Strategies to mitigate PTSD, enhance resiliency, and incorporate psychological care into injury rehabilitation programs for women may be needed for future U.S. military conflicts where they will play a larger role in combat operations.

Sex Differences in Postinjury Health Profiles Among U.S. Military Personnel Following Deployment-Related Concussion.

Background: Women in the U.S. military are now authorized to serve in direct combat occupations. This may increase their risk of combat injuries, such as concussion, in future conflicts. Knowledge of sex differences in health profiles after concussion is paramount for military medical planning efforts. The purpose of this study was to assess sex-related differences in health profiles among U.S. military personnel following deployment-related concussion. Materials and Methods: We conducted a retrospective study of service members who sustained a concussion during combat deployment between 2004 and 2013. Postinjury diagnoses were abstracted from outpatient encounters in electronic health records for 24 months after concussion. We used hierarchical clustering to identify clusters, termed "health profiles," and logistic regression to determine whether sex predicted membership in the health profiles. Results: The study sample included 346 women and 4536 men with deployment-related concussion. Five postinjury health profiles were identified and classified as no morbidity, back pain, tinnitus/memory loss, posttraumatic stress disorder/postconcussion syndrome, and multimorbidity. Women relative to men had higher odds of membership in the back pain (odds ratio [OR] = 1.32; 95% confidence interval [CI] = 1.05-1.67) and multimorbidity profiles (OR = 1.44; 95% CI = 1.03-2.00) and lower odds than men in the tinnitus/memory loss profile (OR = 0.62; 95% CI = 0.42-0.91). Conclusions: Postinjury health profiles among U.S. service members differ by sex following deployment-related concussion, particularly with a higher burden of multimorbidity among women than men, which may require interdisciplinary care. Women also had higher odds of membership in the back pain profile and lower odds in the tinnitus/memory loss profile than men. To prepare for future military operations where women may have greater exposure to combat, continued research elucidating health-related sex differences after deployment-related concussion is imperative.

Morphine use after combat injury in Iraq and post-traumatic stress disorder.

BACKGROUND: Post-traumatic stress disorder (PTSD) is a common adverse mental health outcome among seriously injured civilians and military personnel who are survivors of trauma. Pharmacotherapy in the aftermath of serious physical injury or exposure to traumatic events may be effective for the secondary prevention of PTSD. METHODS: We identified 696 injured U.S. military personnel without serious traumatic brain injury from the Navy-Marine Corps Combat Trauma Registry Expeditionary Medical Encounter Database. Complete data on medications administered were available for all personnel selected. The diagnosis of PTSD was obtained from the Career History Archival Medical and Personnel System and verified in a review of medical records. RESULTS: Among the 696 patients studied, 243 received a diagnosis of PTSD and 453 did not. The use of morphine during early resuscitation and trauma care was significantly associated with a lower risk of PTSD after injury. Among the patients in whom PTSD developed, 61% received morphine; among those in whom PTSD did not develop, 76% received morphine (odds ratio, 0.47; P<0.001). This association remained significant after adjustment for injury severity, age, mechanism of injury, status with respect to amputation, and selected injury-related clinical factors. CONCLUSIONS: Our findings suggest that the use of morphine during trauma care may reduce the risk of subsequent development of PTSD after serious injury.

The Psychological Consequences of Combat Injury Among U.S. Navy Health Care Personnel.

INTRODUCTION: Military health care personnel face numerous risks to mental health, including those associated with combat injury, although no study has described combat injuries within this subgroup or assessed their impact on mental health outcomes. MATERIALS AND METHODS: Male U.S. Navy-enlisted health care personnel, or corpsmen, with combat injury were identified from clinical records. Noninjured corpsmen were matched to injured corpsmen with a 4:1 ratio on year of deployment end or injury and location (Iraq or Afghanistan). The final study population included 2,025 corpsmen (405 injured and 1,620 noninjured). Mental health disorders assessed included posttraumatic stress disorder (PTSD), anxiety, adjustment, mood, and substance abuse disorders. Stratified Cox models were used for analysis while controlling for additional covariates, and injury severity was evaluated as a predictor. RESULTS: Injuries primarily involved the head/neck (73.8%) and extremities (45.7%), and overall injury severity was mostly mild-to-moderate (85.9%). Injured relative to noninjured corpsmen had greater risk of PTSD (risk ratio [RR] 2.45, 95% confidence interval [CI] 2.05 to 2.94), anxiety disorder (RR 1.61, 95% CI 1.32 to 1.96), adjustment disorder (RR 1.88, 95% CI 1.55 to 2.27), mood disorder (RR 1.44, 95% CI 1.16 to 1.79), and substance abuse (RR 1.48, 95% CI 1.14 to 1.91). More severe injuries yielded stronger associations with PTSD (RR 3.57, 95% CI 2.48 to 5.14), anxiety disorder (RR 2.53, 95% CI 1.74 to 3.69), and adjustment disorder (RR 2.17, 95% CI 1.44 to 3.27). CONCLUSIONS: U.S. Navy corpsmen are at risk of combat injury and associated mental health disorders. Injured corpsmen should be screened for mental health problems in the acute phase postinjury, during their remaining time in theater, and after returning home. Future research should address how combat injury compares with other stressors that health care personnel experience and whether the psychological consequences of these injuries (e.g., PTSD) negatively impact work performance and increase risk of burnout.

Is Prehospital Ketamine Associated With a Change in the Prognosis of PTSD?

INTRODUCTION: Ketamine is an alternative to opioids for prehospital analgesia following serious combat injury. Limited research has examined prehospital ketamine use, associated injuries including traumatic brain injury (TBI) and PTSD outcomes following serious combat injury. MATERIALS AND METHODS: We randomly selected 398 U.S. service members from the Expeditionary Medical Encounter Database who sustained serious combat injuries in Iraq and Afghanistan, 2010-2013. Of these 398 patients, 213 individuals had charted prehospital medications. Clinicians reviewed casualty records to identify injuries and all medications administered. Outcomes were PTSD diagnoses during the first year and during the first 2 years postinjury extracted from military health databases. We compared PTSD outcomes for patients treated with either (a) prehospital ketamine (with or without opioids) or (b) prehospital opioids (without ketamine). RESULTS: Fewer patients received prehospital ketamine (26%, 56 of 213) than only prehospital opioids (69%, 146 of 213) (5%, 11 of 213 received neither ketamine nor opioids). The ketamine group averaged significantly more moderate-to-serious injuries, particularly lower limb amputations and open wounds, compared with the opioid group (Ps < .05). Multivariable regressions showed a significant interaction between prehospital ketamine (versus opioids) and TBI on first-year PTSD (P = .027). In subsequent comparisons, the prehospital ketamine group had significantly lower odds of first-year PTSD (OR = 0.08, 95% CI [0.01, 0.71], P = .023) versus prehospital opioids only among patients who did not sustain TBI. We also report results from separate analyses of PTSD outcomes among patients treated with different prehospital opioids only (without ketamine), either morphine or fentanyl. CONCLUSIONS: The present results showed that patients treated with prehospital ketamine had significantly lower odds of PTSD during the first year postinjury only among patients who did not sustain TBI. These findings can inform combat casualty care guidelines for use of prehospital ketamine and opioid analgesics following serious combat injury.

A Grounded Theory Approach to Navigating Infertility Care During U.S. Military Service.

INTRODUCTION: In this study, we aimed to understand how active duty service members and their partners navigate the infertility care process within the Military Health System (MHS) while managing a military career. MATERIALS AND METHODS: We obtained Institutional Review Board approval to employ a qualitative design using grounded theory methods. We recruited participants using purposive sampling, followed by theoretical sampling. We derived data from demographic questionnaires and semi-structured interviews. Consistent with grounded theory methods, we began analysis with line-by-line coding and moved to focused coding. We employed constant comparative analysis throughout the process to name, categorize, and conceptualize data and relationships. RESULTS: The participants included 28 patients, five partners, nine health care providers, and two military leaders. The infertility care process began with active duty service members and their partners recognizing the desire to have a child and discovering infertility, followed by deciding to seek infertility care. The experience was temporally bound within the context of the military environment. We identified the following themes, which described facilitators and barriers to accessing care: Duty station location, career stage, military versus the civilian cost of services, command climate, and policy. These facilitators and barriers varied widely across the Department of Defense (DoD), which resulted in fragmented and inconsistent care cycles, contributed to emotional and physical stress, and created tension between career progression and family formation. CONCLUSIONS: Understanding how military couples perceive and manage demands of infertility care may enhance access to care, decrease patient costs, improve outcomes, result in better support for military couples who experience infertility, and ultimately improve the health and military readiness of our armed forces. The results support the need for action by providers, policy makers, and military leaders to develop effective infertility treatment programs and policies in the DoD.

Health Profiles of Military Women and the Impact of Combat-Related Injury.

PURPOSE: The role of women in the United States military is expanding. Women are now authorized to serve in all military occupations, including special operations and frontline combat units, which places them at increased risk of combat exposure and injury. Little is known regarding the impact of these injuries on the health of military women. METHODS: We conducted a retrospective matched cohort study of women service members who were injured during combat operations in Iraq and Afghanistan. Injured women were individually matched to non-injured controls at a 1:4 ratio. Medical diagnostic codes were abstracted from outpatient encounters in electronic health records, and hierarchical clustering was conducted to identify clusters of diagnostic codes, termed "health profiles." Conditional logistic regression was used to determine whether combat-related injury predicted membership in the profiles. RESULTS: The study sample included 590 injured women and 2360 non-injured controls. Cluster analysis identified six post-deployment health profiles: low morbidity, anxiety/headache, joint disorders, mixed musculoskeletal, pregnancy-related, and multimorbidity. Combat-related injury predicted membership in the anxiety/headache (odds ratio, 1.73; 95% confidence interval, 1.38-2.16) and multimorbidity (odds ratio, 3.43; 95% confidence interval, 2.65-4.43) profiles. CONCLUSIONS: Combat-related injury is associated with adverse post-deployment health profiles among military women, and women with these profiles may experience increased health care burden. As future conflicts will likely see a greater number of women with combat exposure and injury, health outcomes research among military women is paramount for the purposes of medical planning and resource allocation.

Rapid Sequence Induction Strategies Among Critically Injured U.S. Military During the Afghanistan and Iraq Conflicts.

INTRODUCTION: Rapid sequence intubation of patients experiencing traumatic hemorrhage represents a precarious phase of care, which can be marked by hemodynamic instability and pulseless arrest. Military combat trauma guidelines recommend reduced induction dose and early blood product resuscitation. Few studies have evaluated the role of induction dose and preintubation transfusion on hemodynamic outcomes. We compared rates of postintubation systolic blood pressure (SBP) of < 70 mm Hg, > 30% drop in SBP, pulseless arrest, and mortality at 24 hours and 30 days among patients who did and did not receive blood products before intubation and then examined if induction agent and dose influenced the same outcomes. MATERIALS AND METHODS: A retrospective analysis was performed of battle-injured personnel presenting to surgical care facilities in Iraq and Afghanistan between 2004 and 2018. Those who received blood transfusions, underwent intubation, and had an Injury Severity Score of ≥15 were included. Intubation for primary head, facial, or neck injury, burns, operative room intubations, or those with cardiopulmonary resuscitation in progress were excluded. Multivariable logistic regression was performed with unadjusted and adjusted odds ratios for the five study outcomes among patients who did and did not receive preintubation blood products. The same analysis was performed for patients who received full or excessive versus partial induction agent dose. RESULTS: A total of 153 patients had a mean age of 24.9 (SD 4.5), Injury Severity Score 29.7 (SD 11.2), heart rate 122.8 (SD 24), SBP 108.2 (SD 26.6). Eighty-one (53%) patients received preintubation blood products and had similar characteristics to those who did not receive transfusions. Adjusted multivariate analysis found odds ratios as follows: 30% SBP decrease 9.4 (95% CI 2.3-38.0), SBP < 70 13.0 (95% CI 3.3-51.6), pulseless arrest 18.5 (95% CI 1.2-279.3), 24-hour mortality 3.8 (95% CI 0.7-21.5), and 30-day mortality 1.3 (0.4-4.7). In analysis of induction agent choice and comparison of induction agent dose, no statistically significant benefit was seen. CONCLUSION: Within the context of this historical cohort, the early use of blood products conferred a statistically significant benefit in reducing postintubation hypotension and pulseless arrest among combat trauma victims exposed to traumatic hemorrhage. Induction agent choice and dose did not significantly influence the hemodynamic or mortality outcomes.

The use of temporary vascular shunts in military extremity wounds: a preliminary outcome analysis with 2-year follow-up.

BACKGROUND: The use of temporary vascular shunts (TVS)s in the management of wartime extremity vascular injuries has received an increasing amount of attention. However, the overall impact of this adjunct remains incompletely defined. The objective of this study is to characterize outcomes of those patients who suffered wartime extremity vascular injuries managed with TVSs. METHODS: This is a retrospective review of the Navy and Marine Corps Combat Trauma Registry examining peripheral vascular injuries treated during the military conflicts in the Middle East. Patient demographics, injury severity score, mechanism of injury, and vessels injured were recorded. Operative reports were reviewed for use of TVSs, type of definitive repair, the need for amputation, and survival. RESULTS: Eighty patients were included. Forty-six (57%) had TVSs placed and 34 (43%) underwent repair at initial presentation. The mean injury severity score for the TVS group and the non-TVS groups were 15.0 +/- 5.05 and 12.9 +/- 10.18, respectively, (p = 0.229). There were a total of 13 amputations, 6 (13%) in the TVS group and 7 (21%) in the non-TVS group (p = 0.38). There was no difference in amputation rates between either group. There were no recorded mortalities in either group. Median patient follow-up was 24.5 months (range, 3-48 months). CONCLUSIONS: This study demonstrates the importance and utility of TVSs in the management of wartime extremity vascular injury. When used to restore perfusion to an injured extremity, there seems to be no adverse effects or overall increase in limb loss rates and therefore a useful adjunct in the surgery for limb salvage.

Use of recombinant factor VIIA for control of combat-related haemorrhage.

BACKGROUND: Recombinant activated human coagulation factor VII (rFVIIa), an intravascular strategy to promote clotting, is being used as an adjunct to surgical control of bleeding in combat trauma patients. OBJECTIVE: To describe the initial experiences with rFVIIa administered to combat casualties at US Navy-Marine Corps medical treatment facilities in Iraq, and to compare survival outcomes of those treated with rFVIIa to controls not receiving rFVIIa. METHODS: Medical encounter data from the US Navy-Marine Corps Combat Trauma Registry were retrospectively reviewed to identify all battle-injured patients documented as having received rFVIIa during the period May 2004 to January 2006 of Operation Iraqi Freedom. Available clinical and injury related data are presented to characterise the patients. To assess effects of rFVIIa on survival outcomes, rFVIIa cases were matched to controls on injury severity and age. RESULTS: 22 battle-injured patients from the Combat Trauma Registry received rFVIIa. Primarily young US Marines, these patients typically had penetrating injuries from improvised explosive devices and gunshot wounds. Injuries were often abdominal. The average dose used was similar to that reported in another study of civilian trauma patients, although dosing varies widely in the existing experimental and anecdotal literature. Over two-thirds (68%) of the rFVIIa patients survived-an identical outcome seen for a matched control group of 22 patients. CONCLUSIONS: Survival of seriously injured combat casualties was good, although identical to that of a control group. Methodological limitations of this retrospective study preclude making firm conclusions about the effectiveness of rFVIIa. Future controlled studies are needed for safety and efficacy testing of rFVIIa in combat trauma patients.

Gender Differences in Mental Health Screening Outcomes Among U.S. Marines in Combat Support Occupations.

BACKGROUND: The role of women in the U.S. Military has expanded over the years. Recent policy changes allow for women to serve in all military occupations, including direct combat. Multiple studies have identified a higher risk of mental health problems with increasing levels of combat, but little is known regarding gender differences among specific combat support occupations. METHODS: A total of 15,900 U.S. Marines (1,065 women and 14,835 men) with a deployment between 2007 and 2009 were identified from electronic military records. A standard health questionnaire was completed at the end of deployment, which queried the service member on combat exposure and mental health. Mental health problems were defined as screening positive for post-traumatic stress disorder or depression, or receiving a mental health referral. Military occupation was categorized as electrical/mechanical repair, communications/intelligence, functional support/administration, and service/supply. RESULTS: Overall, men reported more combat exposure than women. The communications/intelligence and service/supply occupations had the highest rates of combat exposure. After adjusting for combat exposure, previous diagnosis of anxiety or depression, deployment time, age, and military rank, women had higher odds than men for mental health problems in service/supply (odds ratio, 1.76; 95% confidence interval, 1.21-2.56) and communications/intelligence occupations (odds ratio, 1.60; 95% confidence interval, 1.01-2.52). CONCLUSIONS: As women become fully integrated into the military, the study of health disparities becomes essential for medical planning purposes. Occupation-specific exposures should be considered, along with combat exposures, when determining a risk profile for adverse mental health outcomes among women and men after wartime deployment.

Traumatic brain injury during Operation Iraqi Freedom: findings from the United States Navy-Marine Corps Combat Trauma Registry.

OBJECT: The purpose of this study was to characterize traumatic brain injuries (TBIs) among military personnel (primarily Marines) during the second phase of Operation Iraqi Freedom from early in the medical care chain of evacuation through Landstuhl Regional Medical Center, a Level 4 American hospital in Germany. METHODS: Data were obtained from the Navy-Marine Corps Combat Trauma Registry (CTR) and included both battle and nonbattle injuries. Follow-up of patients with TBI was conducted to examine the short-term medical and personnel-related effects of TBI among those surviving. RESULTS: Those injured in battle were more likely than those not injured in battle to have multiple TBI diagnoses, a greater number of all diagnoses, more severe TBIs, and to be medically evacuated. Intracranial injuries (for example, concussions) were the predominant type of TBI, although skull fractures and open head wounds were also seen. Improvised explosive devices were the most common cause of TBIs among battle injuries; blunt trauma and motor vehicle crashes were the most common causes among nonbattle injuries. Short-term follow-up of surviving patients with TBI indicated higher morbidity and medical utilization among the patients with more severe TBI, although mental conditions were higher among patients with milder TBI. CONCLUSIONS: Data from the Navy-Marine Corps CTR provide useful information about combatants' TBIs identified early in the combat casualty process. Results may improve clinical care for those affected and suggest strategies for primary prevention. The CTR staff plans to conduct additional follow-up studies of this group of patients with TBI.

Head, face, and neck injuries during Operation Iraqi Freedom II: results from the US Navy-Marine Corps Combat Trauma Registry.

BACKGROUND: Head, face, and neck injuries (HFNIs) are an important source of combat mortality and morbidity. The objective of this study was to document the characteristics and causes of HFNIs during Operation Iraqi Freedom II. METHODS: A retrospective review of HFNIs sustained by US military casualties between March 1, 2004 and September 30, 2004 was performed. Data were collected from the Navy-Marine Corps Combat Trauma Registry. RESULTS: During the study period, 39% of all injury casualties in the registry had HFNIs. Of the 445 HFNI patients, one-third presented with multiple wounds to the head, face, and neck. Four percent of battle HFNI patients died from wounds, and nearly 40% of the surviving wounded were evacuated for treatment. Improvised explosive devices (IEDs) were the most frequent cause of battle HFNIs. Nonbattle HFNIs were most often the result of motor vehicle crashes. The majority (65%) of all HFNIs were to the face. Head injuries, overall, were more severe than face or neck wounds according to the Abbreviated Injury Scale. CONCLUSIONS: The proportion of combat-related HFNIs is increasing and is primarily caused by IEDs. Improved protection for the vulnerable facial region is needed. Continued research on the changing nature of warfare and distribution of HFNIs is necessary to enhance the planning and delivery of combat casualty medical care.

Combat amputees' health-related quality of life and psychological outcomes: A brief report from the wounded warrior recovery project.

BACKGROUND: This study extends what is known about long-term health-related quality of life (HrQoL) and other psychosocial outcomes (i.e., depression, posttraumatic stress disorder [PTSD]) among US military combat amputees serving in Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn. METHODS: A total of 63 combat amputees were identified from the Wounded Warrior Recovery Project, a study assessing long-term self-reported HrQoL and psychological outcomes among those wounded during military service. Another 477 service members from the Wounded Warrior Recovery Project were identified as a comparison group (i.e., nonamputees with moderate to severe extremity injuries). RESULTS: After adjusting for age, time since injury, overall injury severity, and traumatic brain injury, amputees had poorer functional HrQoL than those in the nonamputee comparison group overall and in the specific area related to performance of usual activities, and, to some degree, chronic and acute symptoms, and mobility/self-care. On the other hand, depression and PTSD symptoms were not different for the two groups. CONCLUSION: Results suggest that when assessed over 5 years postinjury, on average, amputees have unique physical and functional limitations, yet do not report greater depression or PTSD symptoms than others seriously injured in combat. It may be that state-of-the-art integrated amputee care that includes support networks and emphasis on adjustment and psychological health may increase successful coping and adjustment, at least to a level that is on par with other types of serious combat injury. LEVEL OF EVIDENCE: Epidemiologic/prognostic study, level III.

Characterization and Comparison of Combat-Related Injuries in Women During OIF and OEF.

Although historically restricted from combat roles, women suffer from combat-related injuries, especially in recent conflicts where asymmetrical warfare erases distinctions between forward and rear operating areas. U.S. servicewomen who sustained combat-related injury in Operation Iraqi Freedom (OIF) or Operation Enduring Freedom (OEF) between January 2003 and May 2014 were identified from the Expeditionary Medical Encounter Database. Injuries were characterized using Abbreviated Injury Scale and International Classification of Diseases, 9th Revision codes. Of the 844 combat-related injury episodes in women, 51% (n = 433) were OIF injuries and 49% (n = 411) were OEF injuries. Blast events were responsible for 90% of injuries. The average Injury Severity Score was 3, with no statistical difference in means between OIF and OEF. Of significance were increased head injuries in OEF compared with OIF (80% vs. 48%; p < 0.001). Although the majority of combat-related injuries suffered by women were mild, some women suffered life-threatening injuries, and nearly 65% of the injury episodes resulted in more than one injury. More research is needed as the roles of women in the military continue to expand. Future studies will investigate quality of life outcomes and gender differences in combat-related injuries.

Battlefield extremity injuries in Operation Iraqi Freedom.

OBJECTIVE: Extremity injuries account for the majority of wounds incurred during US armed conflicts. Information regarding the severity and short-term outcomes of patients with extremity wounds, however, is limited. The aim of the present study was to describe patients with battlefield extremity injuries in Operation Iraqi Freedom (OIF) and to compare characteristics of extremity injury patients with other combat wounded. PATIENTS AND METHODS: Data were obtained from the United States Navy-Marine Corps Combat Trauma Registry (CTR) for patients who received treatment for combat wounds at Navy-Marine Corps facilities in Iraq between September 2004 and February 2005. Battlefield extremity injuries were classified according to type, location, and severity; patient demographic, injury-specific, and short-term outcome data were analysed. Upper and lower extremity injuries were also compared. RESULTS: A total of 935 combat wounded patients were identified; 665 (71%) sustained extremity injury. Overall, multiple wounding was common (an average of 3 wounds per patient), though more prevalent amongst patients with extremity injury than those with other injury (75% vs. 56%, P<.001). Amongst the 665 extremity injury patients, 261 (39%) sustained injury to the upper extremities, 223 (34%) to the lower extremities, and 181 (27%) to both the upper and lower extremities. Though the total number of patients with upper extremity injury was higher than lower extremity injury, the total number of extremity wounds (n=1654) was evenly distributed amongst the upper and lower extremities (827 and 827 wounds, respectively). Further, lower extremity injuries were more likely than the upper extremity injuries to be coded as serious to fatal (AIS>2, P<.001). CONCLUSIONS: Extremity injuries continue to account for the majority of combat wounds. Compared with other conflicts, OIF has seen increased prevalence of patients with upper extremity injuries. Wounds to the lower extremities, however, are more serious. Further research on the risks and outcomes associated with extremity injury is necessary to enhance the planning and delivery of combat casualty medical care.
