Prehospital and Retrieval Medicine: Decision-Making Before the Hospital

In brief: Before the hospital, the clinician treats physiology while managing hazards, movement, time, destination and the limits of care in transit. Practise this approach in The Ship Doctor app before working beyond reliable specialist support.

The prehospital mindset

Prehospital and retrieval medicine begins before a complete diagnosis is available. The clinician must identify immediate threats, decide which interventions are worth performing now and move the patient toward the right destination. Time, access and transport physiology shape every choice.

The scene may remain dangerous. Traffic, weather, machinery, water, violence, unstable structures and aviation hazards can injure rescuers or interrupt care. A technically perfect intervention is not useful if it delays extraction from an unsafe environment or cannot be maintained during movement.

Think in parallel: resuscitation, packaging, communication, route and destination. The team should know the clinical priorities and the transport plan early, then update both as the patient responds.

Scene assessment and priorities

Begin with a rapid scene survey: hazards, number of patients, mechanism, access, available resources and likely extraction time. Triage when necessary, then address catastrophic haemorrhage, airway, breathing and circulation. Prevent heat loss from the start because exposure and long scene times can worsen coagulopathy and discomfort.

Interventions should have a clear purpose. Haemorrhage control, oxygen when indicated, ventilation, analgesia, splintage, glucose correction and selected medications can make transport safer. Procedures that carry substantial complication risk need an equally strong benefit and a plan for monitoring.

Reassess after every move. Lifting, loading, altitude, vibration and limited access can reveal instability that was not obvious on the ground.

Packaging and transfer decisions

Packaging protects physiology and preserves access. Secure the airway plan, lines, drains, dressings and splints; place monitoring where it remains visible; and make sure the team can reach essential drugs. Anticipate nausea, agitation, pain, temperature change and battery or oxygen depletion.

Destination choice is a clinical intervention. Bypassing a nearby facility may save time to definitive trauma, stroke, cardiac or obstetric care, but only when the patient can tolerate the longer journey and the receiving centre accepts the transfer. Local protocols and real-time service availability matter.

For retrieval teams, compare the capability at the sending site with capability in transit. Stabilisation before departure is useful when it corrects a reversible threat; waiting for an ideal state can be harmful when definitive treatment is time-critical.

The handover that saves time

A pre-alert lets the receiving team prepare people, space, blood, imaging and procedures before arrival. Give age, problem or mechanism, key findings, trend, treatments, response, estimated arrival and specific requirements. Do not bury the main threat in a complete history.

At the bedside, use a structured handover such as ATMIST or SBAR while one person maintains clinical responsibility. State uncertainties and events during transport. Transfer documentation, medication times and property without delaying urgent care.

Close the loop. Confirm that the receiver has understood the critical issue and accepted responsibility. A concise handover is not a rushed handover; it is prioritised information delivered at the right time.

A practical remote-care framework

For prehospital and retrieval medicine, a useful field framework is to separate the case into four questions. First, what threatens life in the next minutes? Second, what information can genuinely change treatment with the tools available? Third, what capability will the patient need over the next several hours? Fourth, how long does it take to reach that capability in the current conditions? This keeps immediate care and logistics connected.

Document the timeline, trend, important negatives, interventions and response. Remote consultations become safer when the receiving clinician can see what changed and when. State limitations plainly: unavailable tests, staffing, stock, communications, weather and transport. A capability gap is clinical information.

Use a pause point after initial treatment. Recheck the patient, equipment, oxygen, medication supply, destination and backup plan. Ask a colleague to challenge the working diagnosis where possible. This short reset helps detect fixation and makes the next decision deliberate rather than reactive.

Common failure modes

The first failure is waiting for certainty before escalating. Remote transfer systems take time, and early contact can be stood down if the patient improves. The second is allowing a score, image or app to overrule concerning physiology. Decision aids organise information; they do not make an unstable patient safe. The third is planning only for the current state rather than the likely journey.

Another common failure is poor handover. Avoid long narratives that hide the central problem. Lead with the threat, give the trajectory and response, explain the capability gap and make a clear request. Closed-loop communication should confirm who is doing what and when the next contact occurs.

Finally, do not let digital readiness replace physical readiness. Offline content still depends on a charged device, familiar interface and current download. Keep essential paper or laminated fallbacks for the highest-risk pathways and rehearse with the exact equipment used in practice.

How to practise before the emergency

Build a short scenario around the most likely presentation in your setting. Begin with realistic observations and ask the clinician to state the first five minutes, the information needed and the threshold for calling help. Add one constraint—failed connectivity, a missing item, worsening weather or a second patient—and continue until a transfer or observation plan is explicit.

Debrief the reasoning rather than only the checklist. What cues were noticed? Which assumptions were made? What action created the most safety? What equipment or protocol change would make the next response easier? Repeat the difficult segment immediately, then revisit the case weeks later to strengthen retrieval.

Clinical governance: align training and real care with local ambulance, HEMS, trauma-network and retrieval-service clinical guidelines. Scope, medicines, procedures and transfer thresholds differ by role and jurisdiction.
