Operational patient care pathway: building pragmatic medical interoperability through health engagements

The future operational demand for medical support in Western militaries will likely outstrip available resources, necessitating burden-sharing through medical interoperability with allies and partners. However, the current North Atlantic Treaty Organization (NATO) model of interoperability through standardisation, while achieving high levels of commonality and integration along the operational patient care pathway (OPCP), is high-cost and resource-intensive. We have termed this model assured interoperability. Assured interoperability, while applicable to well-established partnerships with high-resource nations, is unlikely to be feasible when working with resource-limited partners or, potentially, when in a sustained conflict with a near-peer adversary. In these circumstances, there will be a requirement to develop a far less resource-intensive model of medical interoperability with lower levels of commonality, assurance and standardisation than assured interoperability, but that provides a 'good enough' OPCP for the operational context. We have termed this pragmatic interoperability. By considering these two types of interoperability, the complete continuum of medical interoperability can be mapped with the full spectrum of partners demonstrating increasing levels of interoperability from pragmatic through to assured interoperability, integrateability and interchangeability, reducing the gap between demand and provision of medical support for operations, increasing operational resilience.

Medics as influencers: a historical analysis of British Army military medical exercises in Kenya over two decades

INTRODUCTION

Annual British Army medical training exercises have run in Kenya since the early 1990s, initially with a dual purpose-to deliver the Kenyan Extended Programme of Immunisation (in remote locations) and to undertake austere training. This provided a specific response to a capability gap request from the partner nation, but as this gap closed, the exercise changed in various ways. This study aimed to qualitatively explore the impact of these exercises on the Kenyan healthcare system and the influence and relationships between the nations.

METHODS

Semistructured interviews were conducted for 10 former senior commanders and medical officers who had deployed in key command and clinical positions from 1993 to 2019. Three researchers conducted thematic content analysis on the key-informant interviews.

RESULTS

Five domains with 18 subdomains formed the study's analysis framework. 16 recurring themes were identified and placed into four categories that denote if they were of benefit to the engagement, enabled success, had the potential to cause harm or were a barrier to successful engagement. Three distinct phases of the exercise were identified: supporting Kenyan vaccinations, direct clinical care, training and education.

CONCLUSIONS

This is the first qualitative analysis of the impact of a British Defence Engagement (Health) on the partner nation and UK influence gained through it. It has identified factors which may improve outcomes, namely, ensuring sustainability and continuity between iterations; maintaining enduring stakeholder relationships; responding to a capability gap request; intelligence-led planning with incorporated assessment, monitoring and evaluation; adapting to changes in needs or contextual settings; while ensuring mutual benefit in objective setting. These may be used as the basis for a conceptual framework supporting the planning and execution of high-quality, mutually beneficial Defence Engagement (Health) activities in future. This framework and future research would also benefit from gaining perspectives from the partner nation.

Defence context for the UK's Defence Engagement (Health)

Defence Engagement (DE) has been a core UK Defence task since 2015. DE (Health) is the use of military medical capabilities to achieve DE effects within the health sector to achieve security and defence objectives. DE (Health) practitioners must understand the underlying defence context that shapes these objectives. The strategic context is becoming more uncertain with the return of great power competition layered on enduring threats from non-state actors and transnational challenges. The UK response has been to develop the Integrated Review, outlining four national security and international policy objectives. UK Defence has responded by developing the integrated operating concept, differentiating military activity between operating and warfighting. Engage is one of the three functions of operate activity, which is complementary to the other operate functions of protect and constrain. DE (Health) can play a unique role in engagement, given its ability to develop new partnerships through health-related activity. DE (Health) may be an enabler for other engagements or to enable the protect and constrain functions. This will be dependent on delivering improvement in health outcomes. Therefore, the DE (Health) practitioner must be conversant with both the contemporary defence and global health contexts to deliver effective DE (Health) activities. This is an article commissioned for the DE special issue of BMJ Military Health.

Predictors of massive blood transfusion: a Delphi Study to examine the views of experts

BACKGROUND

Trauma patients requiring massive blood transfusion (MBT) have high morbidity and mortality: early and aggressive use of blood products during immediate resuscitation may improve survival. There is currently a lack of evidence to guide initial identification of these patients which is especially important in areas where plasma may need to be thawed. In the absence of this evidence, this study aimed to robustly evaluate expert opinion by using a Delphi process to identify predictors of massive transfusion. This process can be used to ensure that decision rules include variables that have clinical validity, which may improve translation of rules into clinical practice.

METHODS

An international panel of 35 experts was identified through expert advice against specific criteria. Military and civilian experts from the fields of emergency medicine, critical care, anaesthesia, prehospital care, haematology and general/trauma surgery were included. The Delphi Study was carried out over three rounds. Consensus level was predefined at 80%.

RESULTS

195 statements were generated by the panel of which 97 (49.7%) achieved consensus at the 80% level by the end of round 3. Strikingly no clinical observations reached consensus individually. Metabolic acidosis of a base excess of -5.0 or worse, lactate >5 mmol/L and a low haematocrit on arrival were all considered predictive. Some patterns of injury, but few mechanisms of injury, were considered highly predictive of the need of MBT.

CONCLUSIONS

This Delphi process has produced a list of parameters that expert clinicians felt were predictive for MBT. This list can be used to inform the generation of decision rules. It is of note that many factors used in current decision rules were not valued by clinical experts-this may be a cause for poor uptake of those rules.

WB Cannon: a trauma pioneer

Many papers on hypovolaemia refer to ‘The Preventive Treatment of Wound Shock’ (Cannon WB, Fraser J, Cowell E. 1918. The preventive treatment of wound shock. JAMA 70: 618- 21). It is a practical paper dealing with the sequelae of blood loss, and how to minimize their impact in injured soldiers. Despite constant reference to this work, Cannon is not a name that is often heard in British medical circles, and many of his achievements are not well remembered. He was, however, a key researcher into many aspects of the physiology upon which our medical practice depends today. This brief paper aims to introduce this important gure to a wider circle.
