Scientific research and product development in the United States to address injuries from a radiation public health emergency.

The USA has experienced one large-scale nuclear incident in its history. Lessons learned during the Three-Mile Island nuclear accident provided government planners with insight into property damage resulting from a low-level release of radiation, and an awareness concerning how to prepare for future occurrences. However, if there is an incident resulting from detonation of an improvised nuclear device or state-sponsored device/weapon, resulting casualties and the need for medical treatment could overwhelm the nation's public health system. After the Cold War ended, government investments in radiation preparedness declined; however, the attacks on 9/11 led to re-establishment of research programs to plan for the possibility of a nuclear incident. Funding began in earnest in 2004, to address unmet research needs for radiation biomarkers, devices and products to triage and treat potentially large numbers of injured civilians. There are many biodosimetry approaches and medical countermeasures (MCMs) under study and in advanced development, including those to address radiation-induced injuries to organ systems including bone marrow, the gastrointestinal (GI) tract, lungs, skin, vasculature and kidneys. Biomarkers of interest in determining level of radiation exposure and susceptibility of injury include cytogenetic changes, 'omics' technologies and other approaches. Four drugs have been approved by the US Food and Drug Administration (FDA) for the treatment of acute radiation syndrome (ARS), with other licensures being sought; however, there are still no cleared devices to identify radiation-exposed individuals in need of treatment. Although many breakthroughs have been made in the efforts to expand availability of medical products, there is still work to be done.

Long-term prescription opioid use among US military service members injured in combat.

INTRODUCTION: During the Global War on Terrorism, many US Military service members sustained injuries with potentially long-lasting functional limitations and chronic pain. We sought to understand the patterns of prescription opioid use among service members injured in combat. METHODS: We queried the Military Health System Data Repository to identify service members injured in combat between 2007 and 2011. Sociodemographics, injury characteristics, treatment information, and costs of care were abstracted for all eligible patients. We surveyed for prescription opioid utilization subsequent to hospital discharge and through 2018. Negative binomial regression was used to identify factors associated with cumulative prescription opioid use. RESULTS: We identified 3,981 service members with combat-related injuries presenting during the study period. The median age was 24 years (interquartile range [IQR], 22-29 years), 98.5% were male, and the median follow-up was 3.3 years. During the study period, 98% (n = 3,910) of patients were prescribed opioids at least once and were prescribed opioids for a median of 29 days (IQR, 9-85 days) per patient-year of follow-up. While nearly all patients (96%; n = 3,157) discontinued use within 6 months, 91% (n = 2,882) were prescribed opioids again after initially discontinuing opioids. Following regression analysis, patients with preinjury opioid exposure, more severe injuries, blast injuries, and enlisted rank had higher cumulative opioid use. Patients who discontinued opioids within 6 months had an unadjusted median total health care cost of US $97,800 (IQR, US $42,364-237,135) compared with US $230,524 (IQR, US $134,387-370,102) among those who did not discontinue opioids within 6 months (p < 0.001). CONCLUSION: Nearly all service members injured in combat were prescribed opioids during treatment, and the vast majority experienced multiple episodes of prescription opioid use. Only 4% of the population met the criteria for sustained prescription opioid use at 6 months following discharge. Early discontinuation may not translate to long-term opioid cessation in this population. LEVEL OF EVIDENCE: Epidemiology study, level III.

Assessment of prehospital hemorrhage and airway care using a simulation model.

BACKGROUND: The quality of prehospital care impacts patient outcomes. Military efforts have focused on training revision and the creation of high-fidelity simulation models to address potentially survivable injuries. We sought to investigate the applicability of models emphasizing hemorrhage control and airway management to a civilian population. METHODS: Prehospital health care providers (PHPs) undergoing their annual training were enrolled. A trauma scenario was simulated with two modules: hemorrhage control and airway management. Experienced raters used a validated tool to assess performance. Pearson correlation, logistic regression, and χ tests were used for analysis. RESULTS: Ninety-five PHPs participated with a mean experience of 15.9 ± 8.3 years, and 7.4% reported past military training. The PHPs' overall execution rate of the six hemorrhage control measures varied from 38.9% to 88.4%. The median blood loss was 1,700 mL (interquartile range, 1,043-2,000), and the mean global rater score was 25.0 ± 7.4 (scale, 5-40). There was a significant relationship between PHP profession and past military experience to their consideration of blood transfusion and tranexamic acid. An inverse relationship between blood loss and global rater score was found (r = -0.59, n = 88, p = 1.93 × 10). After simulated direct laryngoscope failure in the airway module, 58% of PHPs selected video laryngoscopy over placement of a supraglottic airway. Eighty-six percent of participants achieved bilateral chest rise in the manikin regardless of management method. Participants reported improved comfort with skills after simulation. CONCLUSION: Our data reveal marginal performance in hemorrhage control regardless of the PHP's prior experience. The majority of PHPs were able to secure an advanced airway if direct laryngoscope was unavailable with a predisposition for video laryngoscopy over supraglottic airway. Our findings support the need for continued training for PHPs highlighting hemorrhage control maneuvers and increased familiarity with airway management options. Improved participant confidence posttraining gives credence to simulation training. LEVEL OF EVIDENCE: Prognostic/epidemiological study, level III.

The PTSD Toolkit for Nurses: Assessment, intervention, and referral of veterans.

Approximately 20% of veterans suffer from posttraumatic stress disorder (PTSD). NPs are well positioned to provide early detection and assist veterans with access to life-saving treatment. The PTSD Toolkit for Nurses helps nurses improve their skills in assessing PTSD and provides a specialized intervention and referral procedure that promotes help-seeking behavior among veterans.

[Medical support of the Persamo-Kirkenes Offensive].

Medical support of the Petsamo-Kirkenes Offensive. W consider the organizational aspects of the healthcare support of Petsamo-Kirkenes Offensive in the Arctic. The conditions and factors that influenced the preparation and conduct of operations are analysed. It is shown that success and effectiveness of medical support of the operation are based on good planning, build-up of forces and means of medical service and manoeuvre, timely evacuation of the wounded and sick, experience of interaction and mutual reinforcement of the Army Medical Services, and the fleet can be used in the development of plans for medical support of diverse groups of troops (forces) in the Far North of Russia.

Initial deployment of the 14th Parachutist Forward Surgical Team at the beginning of the operation Sangaris in Central African Republic.

As part of the operation Sangaris begun in December 2013 in the Central African Republic, the 14th Parachutist Forward Surgical Team (FST) was deployed to support French troops. The FST (role 2 in the NATO classification) is a mobile surgical-medical treatment facility. The main goal of the FST is to assure the initial damage control surgery and resuscitation for combat casualties, allowing for the early evacuation to combat support hospitals (roles 3 or 4), where further treatments are completed. During the first trimester of the operation Sangaris, 42 patients were treated at FST, of whom 29 underwent surgery. Almost 50% of patients operated on were French servicemen. All admissions were emergency admissions. Orthopedic surgery represented two-thirds of surgical interventions executed as a result of the high proportion of limb injuries. Fifty percent of injuries were specifically linked to combat. Surgery in an FST is primarily dedicated to the treatment of combat casualties with hemorrhagic injuries, but additionally plays a part in supporting general medical care of French troops. Medical aid to the general civilian population is justifiable because of the presence of medical treatment facilities, even in the initial implementation of a military operation.

Assessment of pain in less severely ill and injured aeromedical evacuation patients: a prospective field study.

Pain management is vitally important to injured patients being evacuated from the warzone. A prospective assessment of real-time ratings of pain acceptability, intensity, and satisfaction of a convenience sample of 114 less severely ill and injured U.S. military patients being evacuated on Aeromedical Evacuation (AE) missions from Ramstein Air Field, Germany, to Andrews Air Force Base, Maryland, was conducted. Data were collected before and during 12 AE flights in December 2012 and May 2013. Acceptable pain intensity was a median of 6/10 (range 2-9), with 76% of patients indicating an acceptable pain intensity greater than 4. During AE transport, 75% of patients reported at least one pain score≥4. Despite these high pain ratings, there was documentation of administration for only 58% of routine and 48% for as-needed analgesics/adjuvants. Over 47% of patients experienced pain that exceeded their acceptable intensity level, but of those patients with pain that was more severe than acceptable, only 10% rated their satisfaction with their pain management as poor or fair. This is the first study to provide real-time concurrent assessment of pain and pain management during en route care. The worst pain was reported for the hospital to aircraft arrival, suggesting the need for interventions to safely optimize pain management during this handoff period.
