A Consensus Framework for the Humanitarian Surgical Response to Armed Conflict in 21st Century Warfare

Examining nonmilitary and nongovernmental humanitarian surgical capacity and response in armed conflicts: A scoping review of the recent literature

BACKGROUND

Armed conflicts pose a burden on health care services. We sought to assess the surgical capacity and responses of nonmilitary and nongovernmental humanitarian responders in armed conflicts through proxy indicators to identify strategies to address surgical needs.

METHODS

We searched 6 databases for articles/studies from January 1, 2013, to March 10, 2023. We included articles detailing the surgical capacity of nonmilitary, nongovernmental organizations operating in armed conflicts. We defined surgical capacity through indicators including the type and number of surgical procedures; number of operating rooms, surgical beds, surgeons, anesthesiologists, and surgical equipment; and type of anesthesia employed.

RESULTS

We screened 2,187 abstracts and 279 full texts and included 30 articles/studies. Our sample covered 23 countries and 17 surgical specialties. Most publications focused on surgical capacity assessment (63.3%, 19/30) and surgical and clinical outcomes (63.3%, 19/30). Most articles/studies reported surgical capacity indicators at the hospital (56.7%, 17/30) and multinational (26.7%, 8/30) levels. The number (86.7%, 26/30) and type (76.7%, 23/30) of surgical procedures performed were the most commonly reported. More than one half of the articles (53.3%, 16/30) described strategies to meet surgical needs in armed conflicts. Most strategies addressed information management (68.8%, 11/16), health workforce (62.5%, 10/16), and service delivery (62.5%, 10/16).

CONCLUSION

This review collated common approaches for strengthening health care services in armed conflicts. Several articles emphasized strategies for improving information management, service delivery, and workforce capacity. Hence, we call for standardization of response protocols and multilevel collaborations to maintain or even scale up surgical capacity in armed conflicts.

European military surgical teams in combat theater: A survey study on deployment preparation and experience

INTRODUCTION

Adequate (predeployment) training of the nowadays highly specialized Western military surgical teams is vital to ensure a broad range of surgical skills to treat combat casualties. This survey study aimed to assess the self-perceived preparedness, training needs, deployment experience, and post-deployment impact of surgical teams deployed with the Danish, Dutch, or Finnish Armed Forces. Study findings may facilitate a customized predeployment training.

METHODS

A questionnaire was distributed among Danish, Dutch, and Finnish military surgical teams deployed between January 2013 and December 2020 (N = 142). The primary endpoint of self-perceived preparedness ratings, and data on the training needs, deployment experiences, and post-deployment impacts were compared between professions and nations.

RESULTS

The respondents comprised 35 surgeons, 25 anesthesiologists, and 39 supporting staff members, with a response rate of 69.7 % (99/142). Self-perceived deployment preparedness was rated with a median of 4.0 (IQR 4.0-4.0; scale: 1 [very unprepared]-5 [more than sufficient]). No differences were found among professions and nations. Skills that surgeons rated below average (median <6.0; scale: 1 [low]-10 [high]) included tropical disease management and maxillofacial, neurological, gynecological, ophthalmic, and nerve repair surgery. The deployment caseload was most often reported as <1 case per week (41/99, 41.4 %). The need for professional psychological help was rated at a median of 1.0 (IQR 1.0-1.0; scale: 1 [not at all]-5 [very much]).

CONCLUSIONS

Military surgical teams report overall adequate preparedness for deployment. Challenges remain for establishing broadly skilled teams because of a low deployment caseload and ongoing primary specializations. Additional training and exposure were indicated for several specialism-specific skill areas. The need for specific training should be addressed through customized predeployment programs.

Warzone pediatric trauma care: Lessons from civilian medical staff in Kyiv

INTRODUCTION

The article discusses the challenges faced by civilian healthcare providers in Kyiv, Ukraine, during the conflict in treating pediatric trauma resulting from war-related incidents.

METHODS

The authors share their experiences and insights from managing a series of 12 pediatric patients admitted to the Ohmatdyt children's hospital between February 25 and April 1, 2022. During this period, the hospital was under constant threat due to the military conflict.

RESULTS

The patients, ranging in age from 3 months to 17 years, suffered injuries from various causes, including vehicle shootings, explosions, and other traumatic events. The interventions and timely management are discussed, and two detailed clinical cases are presented to illustrate the complexities of treating pediatric trauma in a warzone.

CONCLUSION

In summary, the article sheds light on the unique challenges faced by healthcare providers in a warzone when treating pediatric trauma. It underscores the importance of timely intervention, effective triage, and the utilization of advanced medical techniques to improve patient outcomes in such challenging circumstances.

Capacity Building During Short-Term Surgical Outreach Trips: A Review of What Guidelines Exist

INTRODUCTION

While short-term surgical outreach trips improve access to care in low- and middle-income countries (LMIC), there is rising concern about their long-term impact. In response, many organizations seek to incorporate capacity building programs into their outreach efforts to help strengthen local health systems. Although leading organizations, like the World Health Organization (WHO), advocate for this approach, uniform guidelines are absent.

METHODS

We performed a systematic review, using search terms pertaining to capacity building guidelines during short-term surgical outreach trips. We extracted information on authorship, guideline development methodology, and guidelines relating to capacity building. Guidelines were classified according to the Global-QUEST framework, which outlines seven domains of capacity building on surgical outreach trips. Guideline development methodology frequencies and domain classifications frequencies were calculated; subsequently, guidelines were aggregated to develop a core guideline for each domain.

RESULTS

A total of 35 studies were included. Over 200 individual guidelines were extracted, spanning all seven framework domains. Guidelines were most frequently classified into Coordination and Community Impact domains and least frequently into the Finance domain. Less than half (46%) of studies collaborated with local communities to design the guidelines. Instead, guidelines were predominantly developed through author trip experience.

CONCLUSION

As short-term surgical trips increase, further work is needed to standardize guidelines, create actionable steps, and promote collaborations in order to promote accountability during short-term surgical outreach trips.

Burns management in the military and humanitarian setting

Burns are an unpredictable element of the modern battlespace and humanitarian operations. Most military burns are small and may not be a significant challenge for deployed healthcare assets but usually render the individual combat ineffective until healed. However, larger burns represent a more significant challenge because of the demand for fluid resuscitation therapy, early surgical intervention and regular wound management that can rapidly deplete surgical capabilities. Beyond the initial injury, longer-term consequences, such as psychological morbidity and loss of functional independence, are rarely considered as part of an ongoing care plan. Globally, most of the morbidity and mortality associated with burns are seen in less economically developed countries and are frequently associated with conflicts and natural disasters, but with simple interventions and resources, outcomes in these environments can be markedly improved. Prehospital providers should be confident to manage the initial assessment of a burn, including triaging for evacuation and packaging for safe transfer. This article provides an overview for prehospital providers on the management of thermal burns in military and humanitarian settings, with additional considerations for the management of chemical and electrical injuries.

Provision of trauma care in asymmetric warfare: a conceptual framework to support the decision to implement frontline care services

INTRODUCTION

The emerging trends of asymmetric and urban warfare call for a revision of the needs and the way in which frontline trauma care is provided to affected population. However, there is no consensus on the process to decide when and how to provide such lifesaving interventions in form of Trauma Stabilization Point (TSP).

METHODS

A three-step Delphi method was used to establish consensus. A focus group discussion was convened to propose a framework and develop the list of twenty-one (21) statements for validation of a group of experts.

RESULTS

A panel of twenty-eight (28) experts reviewed the statements and participated to both first and second rounds. Comments and recommendations provided by the FGD and during round 1 were used to analyze the findings of the study. The proposed framework includes five main categories identified as interconnected components that facilitate the decision to implement or not the TSP. A total of sixteen (16) elements distributed across the five categories have been considered as being able to guide the decision to utilize such capability in high-risk security and resource constrained settings.

CONCLUSION

The TSP has the potential to prevent death and disability. The proposed framework and categories add a structure to the decision-making process and represents an important step to support emergency and trauma care planning and implementation efforts.

Strengthening the emergency health response to children wounded by explosive weapons in conflict

The 2022 war in Ukraine has highlighted the unacceptable consequences wrought on civilians and health infrastructure by conflict. Children are among the most vulnerable of those affected and constitute an increasing percentage of non-combatants injured in conflicts globally. A disproportionate number of these injuries are caused by blast mechanisms from munitions including ‘conventional’ landmines and indiscriminate explosive weapons such as barrel bombs and improvised explosive devices. In 21st century conflict, children are no longer only accidental casualties of war, but are increasingly targeted by parties through acts such as bombing of school buses and playgrounds, conscription as child soldiers, and use as human shields. In the present viewpoint article, we review the state of pediatric blast injury studies, synthesizing current understandings of injury epidemiology and identifying gaps in research to advance the field towards a concrete agenda to improve care for this vulnerable population.

Applying the Haddon Matrix to Frontline Care Preparedness and Response in Asymmetric Warfare

Introduction:

Asymmetric warfare and the reaction to its threats have implications in the way far-forward medical assistance is provided in such settings. Investments in far-forward emergency resuscitation and stabilization can contribute to saving lives and increase the resilience of health systems. Thus, it is proposed to extend the use of the Haddon Matrix to determine a set of strategies to better understand and prioritize activities to prepare for and set-up frontline care in the form of Trauma Stabilization Points (TSPs).

Methods:

An expert consensus methodology was used to achieve the research aim. A small subject matter experts’ group was convened to create and validate the content of the Haddon Matrix.

Results:

The result of the expert group consultations presented an overview of TSP Preparedness and Operational Readiness activities within a Haddon Matrix framework. Main strategies to be adopted within the cycle from pre- to post-event had been identified and presented considering the identified opportunities in the context of the possibility of implementation. Of particular importance was the revision of a curriculum that fits the civilian medical system and facilitates its adaptation to the context and available resources.

Conclusion:

The new framework to enhance frontline care preparedness and response using the Haddon Matrix facilitated the identification of a set of strategies to support frontline health care workers in a more efficient manner. Since the existing approach and tools are insufficient for modern warfare, additional research is needed.

Characterization of Humanitarian Trauma Care by US Military Facilities During Combat Operations in Afghanistan and Iraq

OBJECTIVE

To characterize humanitarian trauma care delivered by US military treatment facilities (MTFs) in Afghanistan and Iraq during combat operations.

BACKGROUND

International Humanitarian Law, which includes the Geneva Conventions, defines protections and standards of treatment to victims of armed conflicts. In 1949 these standards expanded to include injured civilians. In 2001, the Global War on Terror began in Afghanistan and expanded to Iraq in 2003. US MTFs provided care to all military forces, civilians, and enemy prisoners. A thorough understanding of the scope, epidemiology, resource requirements and outcomes of civilian trauma in combat zones has not been previously characterized.

METHODS

Retrospective cohort analysis of the Department of Defense Trauma Registry from 2005-2019. Inclusion criteria were civilians and non-NATO coalition personnel (NNCP) with traumatic injuries treated at MTFs in Afghanistan and Iraq. Patient demographics, mechanism of injury, resource requirements, procedures, and outcomes were categorized.

RESULTS

A total of 29,963 casualties were eligible from the Registry. There were 16,749 (55.9%) civilians and 13,214 (44.1%) NNCP. The majority of patients were age >13 years [26,853 (89.6%)] and male [28,000 (93.4%)]. Most injuries were battle-related: 12,740 (76.1%) civilians and 11,099 (84.0%) NNCP. Penetrating trauma was the most common cause of both battle and nonbattle injuries: 12,293 (73.4%) civilian and 10,029 (75.9%) NNCP. Median injury severity score (ISS) was 9 in each cohort with ISS scores ≥ 25 in 2,236 (13.4%) civilians and 1,398 (10.6%) NNCP. Blood products were transfused to 35% of each cohort: 5,850 civilians received a transfusion with 2,118 (12.6%) of them receiving ≥10 units; 4,590 NNCPs received a transfusion with 1,669 (12.6%) receiving ≥ 10 units. MTF mortality rates were civilians 1,263 (7.5%) and NNCP 776 (5.9%). Interventions, both operative and non-operative, were similar between both groups.

CONCLUSIONS

In accordance with International Humanitarian Law, as well as the US military's medical rules of eligibility, civilians injured in combat zones were provided the same level of care as non-NATO Coalition Personnel. Injured civilians and NNCP had similar mechanisms of injury, injury patterns, transfusion needs, and ISS. This analysis demonstrates resource equipoise in trauma care delivered to civilians and NNCP. Hospitals in combat zones must be prepared to manage large numbers of civilian casualties with significant human and material resources allocated to optimize survival. The provision of humanitarian trauma care is resource-intensive, and these data can be used to inform planning factors for current or future humanitarian care in combat zones.

Operation Allies Refuge and Operation Allies Welcome: Military Perioperative and Perianesthesia Nursing Support to the Afghan Evacuation Mission

Nursing has a long and celebrated history of providing life-saving care during crises and periods of great need. Following the government collapse in Afghanistan and the withdrawal of US troops, a severe humanitarian and human rights crisis emerged. The US military participated in one of the largest and most complex humanitarian missions in history to aid Afghan relief efforts. US and coalition forces evacuated more than 130,000 people in the chaotic Allied airlift from the Kabul Airport. The overarching missions, Operation Allies Refuge and Operation Allies Welcome, provided humanitarian support to at-risk Afghan nationals who contributed to the Global War on Terrorism efforts, as well as US citizens living in Afghanistan. Landstuhl Regional Medical Center (LRMC), an overseas military treatment facility located in Germany, supported the healthcare needs of Afghan evacuees and injured US service members during the humanitarian crisis. LRMC clinicians provided emergent, urgent, and specialty care while advocating for evacuee health, wellness, and living conditions. Perioperative and perianesthesia nurses were essential to the humanitarian response, as many evacuees and injured US service members arrived in Germany requiring immediate surgical interventions. In this article, we describe the vital contributions of military perioperative and perianesthesia nurses to the Operation Allies Refuge and Operation Allies Welcome missions, and share our experiences providing humanitarian relief. Military and civilian healthcare planners can learn from our humanitarian relief contributions, experiences, and lessons to strategically prepare their health systems to respond to future crises.

Epidemiology of Patients Treated at the Emergency Department of a Medcins Sans Frontieres Field Hospital During the Mosul Offensive: Iraq, 2017e

BACKGROUND

Armed conflicts constitute a significant public health problem, and the advent of asymmetric warfare tactics creates unique and new challenges to health care organizations providing trauma care in conflicts.

OBJECTIVE

This study aimed to analyze the epidemiology of presentations to a civilian field hospital deployed close to an ongoing conflict.

METHODS

During the 2016-2017 Mosul offensive, the humanitarian organization Médecins Sans Frontières deployed a field hospital 30 km south of Mosul. This study is a retrospective analysis of routinely collected patient data of all presentations to the emergency department (ED) during its period of operation between February 23 and July 18, 2017. Data were collected in Microsoft Excel by health care workers and analyzed in JMP, version 13. Chi-square test was used to compare proportions. A p value < 0.05 was considered significant.

RESULTS

The analysis included 3946 presentations. Most were due to conflict-related injuries, including explosives (40.4%) and firearms (12.9%), which presented in consecutive waves over time. Approximately one-third of presentations (32.3%) were due to medical issues, which outweighed conflict-related presentations toward the latter half of the operational period. Explosives caused most of the mass casualty events. A total of 20 patients (0.5%) died in the ED.

CONCLUSIONS

The study demonstrated a cyclical burden of conflict-related injuries and extensive medical needs, which increased over time. Among conflict-related injuries, explosive etiology predominated and was likely to result in mass casualty incidents. The low mortality might be due to critical but potentially salvageable patients not reaching the hospital in time, owing to the adverse context.

Predicting surgical resource consumption and in-hospital mortality in resource-scarce conflict settings: a retrospective study

Background

In armed conflicts, civilian health care struggles to cope. Being able to predict what resources are needed is therefore vital. The International Committee of the Red Cross (ICRC) implemented in the 1990s the Red Cross Wound Score (RCWS) for assessment of penetrating injuries. It is unknown to what extent RCWS or the established trauma scores Kampala trauma Score (KTS) and revised trauma score (RTS) can be used to predict surgical resource consumption and in-hospital mortality in resource-scarce conflict settings.

Methods

A retrospective study of routinely collected data on weapon-injured adults admitted to ICRC’s hospitals in Peshawar, 2009–2012 and Goma, 2012–2014. High resource consumption was defined as ≥3 surgical procedures or ≥ 3 blood-transfusions or amputation. The relationship between RCWS, KTS, RTS and resource consumption, in-hospital mortality was evaluated with logistic regression and adjusted area under receiver operating characteristic curves (AUC). The impact of missing data was assessed with imputation. Model fit was compared with Akaike Information Criterion (AIC).

Results

A total of 1564 patients were included, of these 834 patients had complete data. For high surgical resource consumption AUC was significantly higher for RCWS (0.76, 95% CI 0.74–0.78) than for KTS (0.53, 95% CI 0.50–0.56) and RTS (0.51, 95% CI 0.48–0.54) for all patients. Additionally, RCWS had lower AIC, indicating a better model fit. For in-hospital mortality AUC was significantly higher for RCWS (0.83, 95% CI 0.79–0.88) than for KTS (0.71, 95% CI 0.65–0.76) and RTS (0.70, 95% CI 0.63–0.76) for all patients, but not for patients with complete data.

Conclusion

RCWS appears to predict surgical resource consumption better than KTS and RTS. RCWS may be a promising tool for planning and monitoring surgical care in resource-scarce conflict settings.

Severe pediatric war trauma: A military-civilian collaboration from retrieval to repatriation

BACKGROUND

Modern conflicts take a disproportionate and increasing toll on civilians and children. Since 2013, hundreds of Syrian children have fled to the Israeli border. Severely injured children were triaged for military airborne transport and brought to civilian trauma centers in Israel. After recovery, these patients returned to their homes in Syria.We sought to describe a unique model of a coordinated military-civilian response for the stabilization, transport, and in-hospital management of severe pediatric warzone trauma.

METHODS

Prehospital and in-hospital data of all severe pediatric trauma casualties transported by military helicopters from the Syrian border were extracted. Data were abstracted from the electronic medical records of military and civilian medical centers' trauma registries.

RESULTS

Sixteen critically injured children with a median age of 9.5 years (interquartile range [IQR], 6.5-11.5) were transported from the Syrian border to Level I and Level II trauma centers within Israel. All patients were admitted to intensive care units. Eight patients underwent lifesaving procedures during flight, 7 required airway management, and 5 required thoracostomy. The median injury severity score was 35 (IQR, 13-49). Seven laparotomies, 5 craniotomies, 3 orthopedic surgeries, and 1 skin graft surgery were performed. The median intensive care unit and hospital length of stay were 6 days (IQR, 3-16) and 34 days (IQR, 14-46), respectively. Fifteen patients survived to hospital discharge and returned to their families.

CONCLUSION

The findings of this small cohort suggest the benefits of a coordinated military-civilian retrieval of severe pediatric warzone trauma.

Epidemiology of Injuries Sustained by Civilians and Local Combatants in Contemporary Armed Conflict: An Appeal for a Shared Trauma Registry Among Humanitarian Actors

BACKGROUND

Conflict-related injuries sustained by civilians and local combatants are poorly described, unlike injuries sustained by US, North Atlantic Treaty Organization, and coalition military personnel. An understanding of injury epidemiology in twenty-first century armed conflict is required to plan humanitarian trauma systems capable of responding to population needs.

METHODS

We conducted a systematic search of databases (e.g., PubMed, Embase, Web of Science, World Health Organization Catalog, Google Scholar) and grey literature repositories to identify records that described conflict-related injuries sustained by civilians and local combatants since 2001.

RESULTS

The search returned 3501 records. 49 reports representing conflicts in 18 countries were included in the analysis and described injuries of 58,578 patients. 79.3% of patients were male, and 34.7% were under age 18 years. Blast injury was the predominant mechanism (50.2%), and extremities were the most common anatomic region of injury (33.5%). The heterogeneity and lack of reporting of data elements prevented pooled analysis and limited the generalizability of the results. For example, data elements including measures of injury severity, resource utilization (ventilator support, transfusion, surgery), and outcomes other than mortality (disability, quality of life measures) were presented by fewer than 25% of reports.

CONCLUSIONS

Data describing the needs of civilians and local combatants injured during conflict are currently inadequate to inform the development of humanitarian trauma systems. To guide system-wide capacity building and quality improvement, we advocate for a humanitarian trauma registry with a minimum set of data elements.

Applying trauma systems concepts to humanitarian battlefield care: a qualitative analysis of the Mosul trauma pathway

BACKGROUND

Trauma systems have been shown to save lives in military and civilian settings, but their use by humanitarians in conflict settings has been more limited. During the Battle of Mosul (October 2016-July 2017), trauma care for injured civilians was provided through a novel approach in which humanitarian actors were organized into a trauma pathway involving echelons of care, a key component of military trauma systems. A better understanding of this approach may help inform trauma care delivery in future humanitarian responses in conflicts.

METHODOLOGY

A qualitative study design was used to examine the Mosul civilian trauma response. From August-December 2017, in-depth semi-structured interviews were conducted with stakeholders (n = 54) representing nearly two dozen organizations that directly participated in or had first-hand knowledge of the response. Source document reviews were also conducted. Responses were analyzed in accordance with a published framework on civilian battlefield trauma systems, focusing on whether the response functioned as an integrated trauma system. Opportunities for improvement were identified.

RESULTS

The Mosul civilian trauma pathway was implemented as a chain of care for civilian casualties with three successive echelons (trauma stabilization points, field hospitals, and referral hospitals). Coordinated by the World Health Organization, it comprised a variety of actors, including non-governmental organizations, civilian institutions, and at least one private medical company. Stakeholders generally felt that this approach improved access to trauma care for civilians injured near the frontlines compared to what would have been available. Several trauma systems elements such as transportation, data collection, field coordination, and post-operative rehabilitative care might have been further developed to support a more integrated system.

CONCLUSIONS

The Mosul trauma pathway evolved to address critical gaps in trauma care during the Battle of Mosul. It adapted the concept of echelons of care from western military practice to push humanitarian actors closer to the frontlines and improve access to care for injured civilians. Although efforts were made to incorporate some of the integrative components (e.g. evidence-based pre-hospital care, transportation, and data collection) that have enabled recent achievements by military trauma systems, many of these proved difficult to implement in the Mosul context. Further discussion and research are needed to determine how trauma systems insights can be adapted in future humanitarian responses given resource, logistical, and security constraints, as well as to clarify the responsibilities of various actors.
