Prolonged Casualty Care: Extrapolating Civilian Data to the Military Context

Association of freeze-dried plasma with 24-h mortality among trauma patients at risk for hemorrhage

BACKGROUND

Blood products form the cornerstone of contemporary hemorrhage control but are limited resources. Freeze-dried plasma (FDP), which contains coagulation factors, is a promising adjunct in hemostatic resuscitation. We explore the association between FDP alone or in combination with other blood products on 24-h mortality.

STUDY DESIGN AND METHODS

This is a secondary data analysis from a cross-sectional prospective observational multicenter study of adult trauma patients in the Western Cape of South Africa. We compare mortality among trauma patients at risk of hemorrhage in three treatment groups: Blood Products only, FDP + Blood Products, and FDP only. We apply inverse probability of treatment weighting and fit a multivariable Cox proportional hazards model to assess the hazard of 24-h mortality.

RESULTS

Four hundred and forty-eight patients were included, and 55 (12.2%) died within 24 h of hospital arrival. Compared to the Blood Products only group, we found no difference in 24-h mortality for the FDP + Blood Product group (p = .40) and a lower hazard of death for the FDP only group (hazard = 0.38; 95% CI, 0.15-1.00; p = .05). However, sensitivity analyses showed no difference in 24-h mortality across treatments in subgroups with moderate and severe shock, early blood product administration, and accounting for immortal time bias.

CONCLUSION

We found insufficient evidence to conclude there is a difference in relative 24-h mortality among trauma patients at risk for hemorrhage who received FDP alone, blood products alone, or blood products with FDP. There may be an adjunctive role for FDP in hemorrhagic shock resuscitation in settings with significantly restricted access to blood products.

Addressing Differences in Knowledge and Experience in Trauma Care Capabilities Among an International Team of Military Medical Care Providers in a Deployed Setting

Military medical personnel are crucial in providing life-saving care at the point of injury (POI) in challenging environments such as combat zones and disaster areas. This article examines the specialized training US Military medical personnel undergo before deployment and the increasing trend of deploying as part of multinational forces in operations like those in Afghanistan with NATO and non-NATO countries. Integrating medical teams from diverse backgrounds poses significant challenges in maintaining a cohesive and efficient team due to varying trauma management training standards and medical practices among the allied forces. Tactical Combat Casualty Care (TCCC) training and the development of clinical practice guidelines (CPG) by the US Joint Trauma Service have been key strategies by the US Military to standardize care. However, the variation in trauma management training among NATO allies and the differences in medical subspecialties and approaches can lead to inefficiencies and reduced effectiveness in a multinational trauma center setting. For instance, the approach to trauma care can significantly differ between the US and European countries, impacting the interoperability and teamwork in multinational medical teams. To address these challenges, the article highlights the importance of standardized medical training programs that include cultural awareness to enhance the effectiveness of multidisciplinary, multinational medical teams. It also underscores the necessity for standardized international trauma training in the face of increasing global conflicts and the potential for large-scale combat operations. The article discusses the "Trauma Tuesday" program implemented in Kabul, Afghanistan, as an example of how intensive training and simulation exercises can improve team dynamics, knowledge, and skills in trauma management among a diverse team from various nations. The need for ongoing education and developing a standard for managing trauma patients in international teams is emphasized to ensure effective communication and coordination. The article suggests that multinational trauma training can significantly improve team cohesion and critical life-saving skills, essential for future battlefields where access to definitive care may be delayed. Further research is recommended to explore the best methods for achieving effective multinational medical team integration and training standardization.

Patterns of on-scene and healthcare system trauma deaths in the Western Cape of South Africa

BACKGROUND

Injuries account for 8% or 4.4 million deaths annually worldwide, with 90% of injury deaths occurring in low- and middle-income countries. Inter-personal violence and road traffic injuries account for most injury deaths in South Africa, with rates among the highest globally. Understanding the location, timing, and factors of trauma deaths can identify opportunities to strengthen care.

METHODS

This is a retrospective cross-sectional secondary analysis of trauma deaths from 2021 to 2022 in the Western Cape of South Africa. Healthcare system trauma deaths were identified from a multicenter study paired with a dataset for on-scene (i.e., prior to ambulance or hospital) trauma deaths in the same jurisdictions. We describe locations, timing, injury factors, and cause of death. We assess associations between those factors.

RESULTS

There were 2418 deaths, predominantly young men, with most (2274, 94.0%) occurring on-scene. The most frequent mechanism of injury for all deaths was firearms (32.6%), followed by road traffic collisions (17.8%). On-scene deaths (33.2%) were significantly more likely to be injured by firearms compared to healthcare system deaths (23.6%) (p-value <0.01). Most healthcare system deaths within 4-24 h of injury occurred in a hospital emergency center. Among healthcare system decedents, half died in the emergency unit.

CONCLUSIONS

We identified a large burden of deaths from interpersonal violence and road traffic collisions, mostly on-scene. In addition to primary prevention, shortening delays to care can improve mortality outcomes especially for deaths occurring within 4-24 h in emergency centers.
