CoROM cast. Wilderness, Austere, Remote and Resource-limited Medicine.Show Notes
This week, Aebhric is again joined by Zach Andrews, who leads the latest episode of CoROM Conversations, which explores the recognition and management of severe malaria in resource-limited and austere environments. Drawing on field-relevant clinical reasoning, the discussion focuses on the progression from uncomplicated to life-threatening disease, with emphasis on Plasmodium falciparum as the primary driver of severe pathology. The conversation highlights the diagnostic challenges faced by remote medics, where laboratory confirmation may be delayed or unavailable, and underscores the importance of clinical pattern recognition, early intervention, and ongoing reassessment. Particular attention is given to complications such as cerebral malaria, severe anaemia, metabolic acidosis, and hypoglycaemia—all of which significantly increase mortality if not rapidly addressed. From a prolonged field care perspective, the episode integrates pragmatic strategies for stabilisation, monitoring, and evacuation decision-making. It reinforces the need for structured patient assessment using frameworks such as CABCDEFGH, along with trending vital signs over time. The discussion ultimately bridges tropical medicine with austere critical care, offering actionable insights for medics operating far from definitive care.
Key Learning Points Severe malaria is a time-critical diagnosis, most commonly associated with Plasmodium falciparum, requiring immediate treatment even before confirmatory testing. Red flag features include altered mental status, respiratory distress, severe anaemia, hypoglycaemia, and shock. Hypoglycaemia is both a complication of malaria and a side effect of treatment (e.g., quinine), necessitating frequent glucose monitoring. In austere environments, clinical diagnosis often precedes laboratory confirmation, requiring high suspicion in febrile patients with travel or endemic exposure. Fluid management must be cautious, balancing the risks of hypovolaemia and pulmonary oedema. Prolonged care requires integration of nursing principles (HITMAN, SHEEP VOMIT) to prevent secondary deterioration. Early administration of parenteral antimalarials (e.g., artesunate where available) is critical to survival. Evacuation planning should be initiated early, but delays must not postpone life-saving interventions.

Clinical Pearls / Take-Home Messages Treat first, confirm later: In suspected severe malaria, delays in treatment increase mortality. Check glucose early and often: Hypoglycaemia can be rapidly fatal and easily missed. Think beyond fever: Altered mental status or respiratory changes may be the first sign of severe disease. Your greatest tool is reassessment: Trends in vital signs are more valuable than single data points. Good nursing care saves lives: Positioning, hydration, hygiene, and monitoring are critical in prolonged care environments.

This week, Aebhric O’Kelly catches up with Dmytro following his graduation from CoROM’s BSc in Remote Paramedic Practice and his successful registration as a paramedic with the UK Health and Care Professions Council (HCPC). Dmytro describes his current work providing medical care on a remote Caribbean island and reflects on previous roles in humanitarian and military medicine in sub-Saharan Africa. He explains why working remotely requires a different clinical mindset—particularly when weather, geography or resources prevent evacuation, and a patient may remain in your care for hours or even days.

This week, Aebhric O’Kelly is joined by Rob Schembri, a Canadian critical care paramedic with Ornge, Ontario’s air ambulance service, and a student on CoROM’s MSc in Austere Critical Care. Rob discusses his journey through critical care paramedicine, his recent move onto a special operations team and why, after decades in the profession, he decided to pursue postgraduate education in austere medicine. His new role includes supporting the transport of patients with high-risk pathogens and mechanical cardiac support, as well as USAR and other specialist operations. The conversation explores the Canadian paramedic system, including the progression from Primary Care Paramedic to Advanced Care Paramedic and ultimately Critical Care Paramedic. Rob explains the extensive training required at the critical care level and how international paramedics can enter the Ontario system. Rob also talks candidly about undertaking his first research project, navigating ethics approval and discovering that the thesis he initially dreaded has become one of the most interesting parts of his MSc. The episode finishes with a discussion about lifelong learning, career development and Rob’s advice to clinicians beginning a career in austere medicine: learn as much as you can, experience as much as you can—and enjoy what you do.
In this episode of the CoROM Podcast, Aebhric O'Kelly speaks with Kevin Fox, a Belgian EMT, maritime security professional and recent graduate of CoROM's BSc in Remote Paramedic Practice. Kevin's journey into medicine began following the 2016 Brussels terrorist attacks. Working in security at the time, he realised he lacked the medical knowledge to help casualties in a similar emergency. That experience eventually led him through tactical medical training, Belgian EMT education and CoROM's three-year degree. Kevin discusses his clinical placements in South Africa and Suriname, where he gained experience managing polytrauma, paediatric emergencies, childbirth and tropical infectious diseases. He describes how resource limitations challenged him to improvise, adapt and develop clinical judgement while working alongside local medical teams. The conversation then turns to tropical medicine in Europe. Kevin shares two memorable ambulance cases involving patients returning from India and Italy, explaining how a detailed travel history helped him recognise possible malaria and dengue. These experiences inspired his proposed research into incorporating recent travel more explicitly into prehospital patient assessment. Kevin also discusses his dissertation on Belgium's dengue preparedness, the importance of community education and his plans for further research and postgraduate study. Finally, he reflects on his three years at CoROM, the value of supervised clinical placements and the importance of recognising one's limitations. His advice to clinicians entering remote medicine is simple: test your equipment, remain self-critical and never become a toxic leader. 00:00 – Introducing Kevin Fox: From maritime security to remote paramedicine. 01:04 – The Brussels Terrorist Attacks: The event that inspired Kevin to pursue medical training. 03:05 – Why a Bachelor's Degree?: Professional development and European academic recognition. 04:30 – Future Academic Ambitions: Tropical medicine and postgraduate opportunities. 06:34 – Clinical Placements in Suriname: How TTEMS prepared Kevin for remote clinical practice. 08:35 – Why Suriname?: Language, culture and healthcare challenges. 10:30 – Working in a Surinamese Emergency Department: Trauma assessment and growing clinical responsibility. 13:12 – Memorable Clinical Cases: Polytrauma, paediatric emergencies and delivering a baby. 14:54 – Tropical Diseases in Suriname: Dengue, chikungunya and patients presenting with sepsis. 16:51 – Knowing Your Limitations: Clinical supervision, teamwork and asking for help. 20:10 – Three Years at CoROM: Practical training, student experiences and suggestions for improvement. 23:11 – Advice for First-Year Students: Why anatomy and physiology matter later in clinical practice. 25:28 – Kevin's Dissertation: Dengue preparedness and the establishment of tiger mosquitoes in Belgium. 28:44 – The Importance of Travel History: Recognising malaria in a patient returning from India. 30:00 – Could It Be Dengue?: A patient returning from Italy challenges clinical assumptions. 32:01 – The SAMPLER Research Project: Investigating tropical fever recognition among Belgian ambulance personnel. 33:48 – Tropical Medicine in Europe: Why clinicians need to consider emerging and imported infections. 35:19 – UK Paramedic Registration: Kevin's professional plans after graduation. 36:05 – Maritime and Offshore Medicine: Combining paramedicine with maritime security. 37:05 – Continuing Education: Tropical medicine, clinical laboratory skills and professional networks. 39:02 – Advice for Austere Clinicians: Never assume, remain self-critical and avoid toxic leadership. 40:25 – Closing Remarks.

In this episode of CoROM Conversations, Bill Vasios is joined by Dr Bob Dichiera, a retired US Army veteran with experience in operational medicine, primary care and orthopaedic surgery, and an associate professor at East Carolina University's PA programme. Bob introduces a practical approach to remote orthopaedics built around four questions: Is the patient dying? Is a limb dying? Can I stabilise it? Does the patient need evacuation? The discussion examines the orthopaedic emergencies that clinicians cannot afford to miss, including open fractures and dislocations, neurovascular compromise, compartment syndrome, vascular injuries, pelvic fractures and traumatic amputations. Throughout the session, Bob emphasises repeated pulse, motor and sensory (PMS) assessment before and after interventions. Using clinical cases, the conversation explores closed and open tibial fractures, field-expedient fracture assessment, compartment syndrome, irrigation and antibiotics, splinting, shoulder dislocations and reduction decisions. The discussion considers when reduction may be appropriate in a remote environment, particularly when prolonged transport is combined with neurovascular compromise. The later discussion examines pelvic and hip injuries, field assessment, ultrasound and the difficult question of whether procedures such as fasciotomy have a role in genuinely remote care. Bob also considers how telemedicine and remote specialist support may extend what clinicians can safely accomplish in austere environments.
This week, Aebhric O'Kelly speaks with Dr Travis Kaufman and they explore his 25-year US Army career, his transition from combat engineer and military diver to Physician Assistant (PA), and five years providing medical support through the White House Medical Unit. Travis describes one of the most difficult lessons emerging from Ukraine: prolonged tourniquet use. A Ukrainian medic explains the decision as “triage of the limb or the life” when attempting tourniquet conversion after several hours may place the casualty at considerable risk. The discussion examines unnecessary tourniquet use, the importance of reassessment, contaminated wounds and the increasing problem of sepsis when evacuation is delayed for hours or days. Travis argues that the traditional TCCC assumption of rapid evacuation can create a training scar when casualties instead remain with combat lifesavers and medics for prolonged periods. The episode then explores what PCC actually looks like in practice: trending observations, wound debridement, antimicrobial planning, pain management, positioning, pulmonary care and the fundamental nursing interventions that can determine whether a casualty deteriorates. Travis also shares examples of improvisation from the field, including improvised PEEP and wound-vacuum techniques, and discusses why clinicians need to rediscover simple solutions when sophisticated equipment is unavailable.
