Despite lacking medical backing, the term 'golden day' has been used by senior military leaders to link the resuscitative benefits of the 'golden hour' to prolonged medical care through similar nomenclature. Pseudomedical terminology can easily enter the lexicon of commanders as attractive soundbites. However, articulating the evidence-based factors influencing mortality on the battlefield is critical to effectively articulate risk to commanders. The challenges of LSCO will be significant with increased casualty numbers and treatment constraints. Realistic medical and operational planning is critical to maximising survival, with a clear understanding of what can and cannot be achieved. Recent improvements in trauma care, such as early haemorrhage control, advanced prehospital care and rapid evacuation to surgical care, have significantly reduced mortality rates. Given the predictability of when casualties die from significant injuries, the absence of timely clinical interventions will increase avoidable battlefield deaths. If evacuation to surgical care is extended to 24 hours, many more casualties will die from potentially survivable injuries. Medical planners must recognise the potential challenges associated with LSCO including contested, delayed evacuation which predicts a tripling of mortality rates from 10% to 30%. Leaders must appreciate the unchanging human physiologic response to injury and historical combat casualty statistics when preparing commanders and politicians for the excess in mortality during LSCO. Without candour, plans will be unrealistic, causing non-medical leaders and the public to be unprepared.</p>","PeriodicalId":48485,"journal":{"name":"Bmj Military Health","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142693673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing triage systems require the rescue of immersed (in water) casualties before triage is undertaken. A tool that enables triage to be undertaken <i>before</i> rescue, and therefore the prioritisation of that rescue, should improve the efficiency, efficacy and survival rate associated with the management of such incidents.In this paper, we describe the rationale and development of a proposed novel 'in-water mass casualty triage tool (IWMCTT)' to assist in the swift and effective triage of those in the water in mass casualty situations <i>before</i> they are rescued, based upon the likelihood of survival <i>after</i> immersion. The tool is based on a review of the literature related to the hazards associated with immersion, most notably drowning.The IWMCTT employs a sequential approach to streamline the identification and prioritisation for rescue of immersed individuals; it considers factors such as hazards, visibility constraints, purposeful swimming, moving or floating, airway position, availability of flotation assistance and flotation device effectiveness. It categorises casualties from W1 (high) to W4 (low) priority for rescue.The proposed IWMCTT offers a potential solution to some of the challenges faced during water-based mass casualty incidents; providing rescue assets (rigid-hulled, inflatable boats, ships and helicopters) with a rapid and effective approach to assess and prioritise individuals for rescue and medical attention, hopefully thereby reducing mortality and morbidity. The IWMCTT requires further evaluation and validation.</p>","PeriodicalId":48485,"journal":{"name":"Bmj Military Health","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142683035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effective evidence-based intervention strategies are essential to reduce MSKI incidence, and research has shown the positive effect of both nutritional interventions and physical training (PT) interventions on reducing MSKI incidence. Levels of vitamin D metabolites have been associated with MSKI and bone stress fracture risk, while calcium and vitamin D supplementation has been shown to reduce the incidence of stress fractures during military training. Protein and carbohydrate supplementation during arduous military training (high volume, high intensity) has also been shown to reduce MSKI risk and the number of limited/missed duty days. PT has played a key role in soldier development to meet the occupational demands of serving in the armed forces. Paradoxically, while PT is fundamental to enhancing soldier readiness, PT can also be a major contributor to MSKI; emerging evidence suggests that the nature of the PT being performed is a risk factor for MSKI. However, strategies like reducing training load and implementing PT programmes using evidence-based training principles can reduce MSKI incidence among military service members by 33-62%, and reduce the financial burdens for military services.
