Advancing Military Medical Planning in Large Scale Combat Operations: Insights From Computer Simulation and Experimentation in NATO's Vigorous Warrior Exercise 2024. Mil Med 2024; 189:456-464. [PMID: 39160876 DOI: 10.1093/milmed/usae152] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 01/18/2024] [Accepted: 03/19/2024] [Indexed: 08/21/2024] Open
Abstract
INTRODUCTION The ongoing conflict in Ukraine from Russian invasion presents a critical challenge to medical planning in the context of multi-domain battle against a peer adversary deploying conventional weapon systems. The potential escalation of preventable morbidity and mortality, reaching a scale unprecedented since World War II, underscores the paramount importance of effective phases of care from Point of Injury (PoI)/Point of Wounding (PoW) or Point of Exposure (PoE) to Role 1 (R1) and Role 2 (R2) echelons of care.The NATO Vigorous Warrior (VW) Live Exercise (LIVEX) serves as a strategic platform for NATO and its partners, providing an opportunity to challenge operational concepts, experiment, innovate life-saving systems, and foster best practices across the Alliance. MATERIALS AND METHODS This study delineates the strategic application of the VW LIVEX platform for the adaptation of the computational simulation software Simulation for the Assessment and Optimization of Medical Disaster Management (SIMEDIS) within the context of Large-Scale Combat Operations (LSCO). The SIMEDIS computer simulator plays a pivotal role by furnishing real-time insights into the evolving injury patterns of patients, employing an all-hazards approach. This simulator facilitates the examination of temporal shifts in medical timelines and the ramifications of resource scarcity against both morbidity and mortality outcomes. The VW LIVEX provides a unique opportunity for systematic validation to evaluate the results of the computer simulator in a realistic setting and identify gaps for future concepts of operations. RESULTS We report the process and methodologies to be evaluated at the VW LIVEX in far forward and retrospective medical support operations. Using the SIMEDIS simulator, we can define battlefield scenarios for varied situations including artillery, drone strikes, and Chemical, Biological, Radiological, Nuclear, and explosive (CBRNe) attacks. Casualty health progressions versus time are dependent on each threat. Mortality is computed based on the concepts found in Tactical Combat Casualty Care (TCCC) of "self-aid"/"buddy-aid" factoring in the application or absence of definitive traumatic hemorrhage control and on the distribution policy of victims to medical treatment facilities through appropriate Command and Control (C2) ("Scoop and Run" versus "Stay and Play"). The number of medical supplies available along with the number of transport resources and personnel are set and are scalable, with their effect on both morbidity and mortality quantified.Concept of Medical Operations can be optimized and interoperability enhanced when shared data are provided to C2 for prospective medical planning with retrospective data. The SIMEDIS simulator determines best practices of medical management for a myriad of injury types and tactical/operational situations relevant to policy making and battlefield medical planning for LSCO. CONCLUSIONS The VW LIVEX provides a Concept Development and Experimentation platform for SIMEDIS refinement and conclusive insights into medical planning to reduce preventable morbidity and mortality. Recommending further iterations of similar methodologies at other NATO LIVEXs for validation is crucial, as is information sharing across the Alliance and partners to ensure best practice standards are met.

Riley MR. How should the Defence Medical Services prepare for an Article 5 NATO collective defence operation with the prospect of high volumes of combat casualties? BMJ Mil Health 2023:military-2023-002396. [PMID: 36997238 DOI: 10.1136/military-2023-002396] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2023] [Accepted: 03/11/2023] [Indexed: 04/01/2023]
Abstract
Since the February 2022 Russian invasion of Ukraine, the prospect of an Article 5 North Atlantic Treaty Organisation collective defence operation in Europe has increased significantly. Were this type of operation to occur, it would present different challenges to the Defence Medical Services (DMS) than those of the era of the International Security Assistance Force in Afghanistan, where air superiority was assured, and combat casualty numbers did not approach the tens of thousands experienced by Russia and Ukraine in the first months following the invasion. This essay examines how the DMS could prepare for such an operation using four key themes: preparing for prolonged field care, training medical personnel for combat, recruiting and retaining medical personnel and planning for post-traumatic stress disorder.

Resuscitation with whole blood or blood components improves survival and lessens the pathophysiological burden of trauma and haemorrhagic shock in a pre-clinical porcine model. Eur J Trauma Emerg Surg 2023; 49:227-239. [PMID: 35900383 PMCID: PMC9925484 DOI: 10.1007/s00068-022-02050-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Accepted: 06/30/2022] [Indexed: 11/03/2022]
Abstract
PURPOSE In military trauma, disaster medicine, and casualties injured in remote locations, times to advanced medical and surgical treatment are often prolonged, potentially reducing survival and increasing morbidity. Since resuscitation with blood/blood components improves survival over short pre-surgical times, this study aimed to evaluate the quality of resuscitation afforded by blood/blood products or crystalloid resuscitation over extended 'pre-hospital' timelines in a porcine model of militarily relevant traumatic haemorrhagic shock. METHODS This study underwent local ethical review and was done under the authority of Animals (Scientific Procedures) Act 1986. Forty-five terminally anaesthetised pigs received a soft tissue injury to the right thigh, haemorrhage (30% blood volume and a Grade IV liver injury) and fluid resuscitation initiated 30 min later [Group 1 (no fluid); 2 (0.9% saline); 3 (1:1 packed red blood cells:plasma); 4 (fresh whole blood); or 5 (plasma)]. Fluid (3 ml/kg bolus) was administered during the resuscitation period (maximum duration 450 min) when the systolic blood pressure fell below 80 mmHg. Surviving animals were culled with an overdose of anaesthetic. RESULTS Survival time was significantly shorter for Group 1 compared to the other groups (P < 0.05). Despite the same triggers for resuscitation when compared to blood/blood components, saline was associated with a shorter survival time (P = 0.145), greater pathophysiological burden and significantly greater resuscitation fluid volume (P < 0.0001). CONCLUSION When times to advanced medical care are prolonged, resuscitation with blood/blood components is recommended over saline due to the superior quality and stability of resuscitation achieved, which are likely to lead to improved patient outcomes.

BMJ Mil Health 2021; 169:e34-e38. [PMID: 33483453 DOI: 10.1136/bmjmilitary-2020-001542] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2020] [Revised: 12/21/2020] [Accepted: 12/27/2020] [Indexed: 11/04/2022]
Abstract
INTRODUCTION The 'golden hour' is a universal paradigm that suggests trauma patients have lower morbidity and mortality when provided with medical care within 1 hour after injury. The objective of this study was to examine whether transport time from point of injury to a military treatment facility (MTF) in-theatre was associated with patient-reported outcomes, such as post-traumatic stress disorder (PTSD), depression and quality of life (QOL), among US service members with combat-related injury. METHODS Participants were injured between March 2003 and March 2016 and completed standardised assessments of PTSD, depression and QOL for theWounded Warrior Recovery Project (WWRP) between January 2013 and November 2017. Multivariable regressions were used to assess the relationship between transport time (≤1 hour or >1 hour from injury to MTF) and positive screens for PTSD and depression, and QOL, respectively.Overall, 45.6% of participants (n=879) arrived at an MTF within 1 hour postinjury. About 8 years passed between when participants were injured on deployment and when they completed their first WWRP assessment. Approximately 48% of participants screened positive for PTSD and 51.3% for depression, with a mean QOL score of 0.513 (SD=0.150). After adjusting for covariates, transport time was not significantly associated with PTSD (OR 1.04, 95% CI 0.79 to 1.38; p=0.77), depression (OR 0.92, 95% CI 0.69 to 1.21; p=0.55) or QOL (β=0.009; p=0.38). CONCLUSION Transport time was not associated with patient-reported outcomes among US service members with combat-related injury. These findings are important as we seek to understand how combat casualties may be affected by extended medical evacuation or transport times anticipated in future expeditionary operations.

Torso body armour coverage defined according to feasibility of haemorrhage control within the prehospital environment: a new paradigm for combat trauma protection. BMJ Mil Health 2020; 168:399-403. [PMID: 33109734 DOI: 10.1136/bmjmilitary-2020-001582] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2020] [Revised: 09/24/2020] [Accepted: 09/29/2020] [Indexed: 11/03/2022]
Abstract
Developments in military personal armour have aimed to achieve a balance between anatomical coverage, protection and mobility. When death is likely to occur within 60 min of injury to anatomical structures without damage control surgery, then these anatomical structures are defined as 'essential'. However, the medical terminology used to describe coverage is challenging to convey in a Systems Requirements Document (SRD) for acquisition of new armour and to ultimately translate to the correct sizing and fitting of personal armour. Many of those with Ministry of Defence responsible for the procurement of personal armour and thereby using SRDs will likely have limited medical knowledge; therefore, the potentially complex medical terminology used to describe the anatomical boundaries must be translated into easily recognisable and measurable external landmarks. We now propose a complementary classification for ballistic protection coverage, termed threshold and objective, based on the feasibility of haemorrhage control within the prehospital environment.
