RESUMEN
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.
RESUMEN
INTRODUCTION: Heat illness among the UK Armed Forces is usually exertional, and therefore preventable, yet the incidence has not reduced since 2011. JSP 539 explicitly states that wet bulb globe temperature (WBGT) should be measured 'at the location of greatest heat risk', not 'that of most convenience'. A handheld WBGT tracker used at point-of-exertion could reduce this incidence if proven to be as accurate as the current in-service device. METHODS: Longitudinal observational comparison and equipment feasibility study of the Kestrel 5400 and QUESTemp 34 (QT-34) in worldwide firm base and deployed UK Armed Forces locations. The locations chosen were Kenya, South Sudan, Belize, Tidworth, Aldershot and Brecon. Paired data points of WBGT readings were collected from November 2017 to August 2018 in all weather conditions. RESULTS: WBGT readings were comparable between the QT-34 and Kestrel 5400 across the UK and overseas. In addition, there was no change in accuracy between readings taken from the Kestrel 5400 when tripod-mounted and handheld. The Kestrel was easy to set up and far less susceptible to resupply or power supply limitations, as it requires no user input for wet bulb temperature, and runs on AA batteries. CONCLUSION: This equipment feasibility study has shown that the Kestrel 5400 gives an acceptable accuracy and is easier to use than the QT-34. The authors recommend that the Kestrel 5400 is introduced as an adjunct to the QT-34, and its use within the military setting monitored through ongoing comparative data collection in a large-scale proof-of-concept study.
