I was two months into my first ship contract when I called the bridge about a passenger with chest pain. The ECG was showing ST elevation. I picked up the phone and told the officer of the watch, clearly and accurately, that the patient was “haemodynamically compromised with ST elevation in leads II, III, and aVF, consistent with an inferior STEMI, and required time-critical percutaneous coronary intervention.” There was a pause. Then the second officer said: “Doctor, is the passenger going to die? What do you need me to do?”
That pause — that silence on the line between my clinical precision and his operational confusion — was the most important lesson of my maritime career. Not because the second officer was unintelligent. He was a competent mariner with years of experience navigating complex situations. But he had no idea what an inferior STEMI was, what haemodynamic compromise meant, or what percutaneous coronary intervention involved. He needed three things from me: is this person in danger, what do I need from the ship, and how much time do we have. I gave him none of those things. I gave him a clinical handover designed for another doctor.
The Language Gap That Kills
This is not a trivial communication problem. It is a systemic failure point in maritime medicine that costs time, and at sea, time is measured in nautical miles, helicopter fuel, and patient survival. The gap between clinical language and command language is not just a matter of vocabulary. It is a difference in purpose. Clinical language is designed to convey diagnostic reasoning among peers who share a common training framework. Command language is designed to trigger decisions and actions among officers who think in terms of headings, ETAs, risk categories, and resource allocation.
When a doctor speaks clinical language to the bridge, the captain or officer must perform real-time translation under stress. They must decode medical terminology they have never been taught, extract the operationally relevant information, and then decide what to do with it. Most of the time, they cannot do this. Not because they lack intelligence, but because the information was never formatted for their decision-making framework.
The result is delay. The officer asks clarifying questions. The doctor repeats the same clinical language, perhaps louder or slower, as if volume and pace were the problem. The officer eventually asks the only question that matters to them: “What do you need me to do?” And the doctor, who has been thinking in diagnoses rather than actions, has to reframe their thinking on the spot. By the time the conversation produces a clear operational request, five or ten minutes have passed. In a cardiac emergency, that is the difference between myocardium that can be saved and myocardium that cannot.
What the Bridge Actually Needs to Hear
The bridge operates on a decision framework built around four questions: What is happening? How serious is it? What needs to change? How much time do we have? Every piece of information the doctor provides should map to one of these four questions. Everything else is noise.
Consider the difference between these two communications:
Clinical: “Captain, I have a 67-year-old male with acute onset chest pain radiating to the left arm, diaphoresis, ST elevation in the inferior leads, blood pressure 90/60, heart rate 110. I've administered aspirin 300mg, GTN sublingual, and morphine 5mg IV. He needs emergency PCI within 90 minutes of symptom onset for optimal outcomes.”
Operational: “Captain, I have a passenger with a serious heart emergency. This is time-critical — every hour of delay reduces his chances of survival. He needs a hospital with a cardiac catheterisation lab. What is the fastest way to get him to one? I need to know our options: nearest port with cardiac capability, helicopter range, and your recommended course of action.”
The first version is clinically impeccable. Any emergency physician would nod in recognition. But it gives the captain almost nothing to work with. The second version tells the captain exactly what he needs to know: the situation is serious, time matters, the patient needs a specific type of hospital, and the doctor is asking for operational options. The captain can act on the second version immediately. The first version requires him to decode, interpret, and then ask what you actually need.
SBAR-M: The Maritime Adaptation
The standard SBAR framework — Situation, Background, Assessment, Recommendation — is widely taught in clinical communication. It is a good framework for handovers between clinicians. But it was not designed for cross-disciplinary communication with a command team that does not share your clinical vocabulary.
The maritime adaptation, which I call SBAR-M, modifies the framework to bridge the language gap:
- Situation: One sentence describing what is happening in plain language. No diagnosis, no jargon. “I have a passenger with a serious heart problem.”
- Severity: Replace “Background” with a severity statement that maps to the bridge's risk categories. “This is time-critical. Without hospital treatment, this patient may die.”
- Action needed: Replace “Assessment” with a specific operational request. “I need the fastest route to a hospital with cardiac surgery capability.”
- Resources and time: Replace “Recommendation” with a resource and time statement. “I can sustain care onboard for approximately 6 hours. After that, our ability to keep this patient alive will degrade.”
- Maritime context: Add a final element that acknowledges the operational constraints. “I understand this may require a course change or speed increase. I am requesting this as a medical priority.”
The SBAR-M structure ensures that every communication to the bridge contains the information the captain needs to make an operational decision, without requiring him to translate clinical terminology in real time.
Examples of Bad vs. Good Communication
Understanding the gap is easier with concrete examples. Here are three common scenarios and how the communication typically goes wrong, followed by how it should go:
Scenario 1: Respiratory failure
Bad: “The patient has type 1 respiratory failure with a PaO2 of 7.2 on room air. I've started high-flow oxygen at 15 litres per minute via a non-rebreather mask and his sats are holding at 88%. He may need intubation if he deteriorates further.”
Good: “Captain, I have a patient who cannot breathe on his own. He is on oxygen support, but our oxygen supply will last approximately 14 hours at this rate. If he gets worse, I will not have the equipment to keep him alive. I need to discuss diversion or helicopter evacuation before our oxygen runs out.”
Scenario 2: Suspected stroke
Bad: “I have a passenger presenting with acute onset left-sided hemiparesis, facial droop, and dysphasia. FAST positive. Onset approximately 90 minutes ago. Within the thrombolysis window but I don't carry tPA onboard.”
Good: “Captain, I have a passenger who is having a stroke. There is a treatment that could prevent permanent brain damage, but it has to be given within a few hours and I do not have it onboard. The faster we can get this patient to a stroke-capable hospital, the better his outcome. What are our fastest options?”
Scenario 3: Traumatic injury with possible internal bleeding
Bad: “Crew member fell from a height, approximately 3 metres. Complaining of left upper quadrant pain, guarding on examination. Concerned about splenic laceration. Tachycardic at 120, BP holding at 100/70 but I'm worried about compensated shock.”
Good: “Captain, a crew member has fallen and I suspect he may be bleeding internally. He is stable right now, but his condition could deteriorate rapidly and without warning. If that happens, he will need emergency surgery that I cannot perform onboard. I recommend we begin planning for evacuation immediately while he is still stable enough to be moved safely.”
Building Your Bridge Phrase Library
The most effective ship doctors do not improvise bridge phrases during emergencies. They prepare them in advance. Before your first emergency at sea, sit down and write out bridge phrases for the ten most common scenarios you expect to encounter: cardiac emergency, respiratory failure, stroke, major trauma, acute abdomen, anaphylaxis, seizure, mental health crisis, obstetric emergency, and cardiac arrest.
For each scenario, draft a sentence that answers the bridge's four questions: what is happening, how serious is it, what needs to change, and how much time you have. Keep each phrase under four sentences. Eliminate every piece of clinical jargon. Read it aloud and ask yourself: would a maritime officer who has never set foot in a hospital understand what I need from them?
The full library of bridge phrase templates, including scenario-specific versions and the complete SBAR-M framework, is available in the Bridge Phrases section of this site and in the Maritime Medicine Playbook.
Communication as a Clinical Skill
Medical schools teach communication as a soft skill — something about empathy and patient rapport. At sea, communication is a hard skill with direct clinical consequences. A bridge phrase that triggers an immediate course change can save a life. A clinical monologue that produces confusion and delay can cost one. The words you choose when you pick up the phone to the bridge are as clinically significant as the drugs you push or the procedures you perform.
The bridge phrase is not a dumbed-down version of your assessment. It is a translation — a precise reframing of clinical information into the operational language that the command team already understands and already has systems to act upon. Learning to construct these phrases is not a compromise of your clinical standards. It is an expansion of your clinical practice to include the operational context that defines medicine at sea.
The best bridge phrase is not the one that most accurately describes the pathology. It is the one that most quickly produces the operational decision the patient needs to survive.
