Uncertainty, multimorbidity and prioritisation

Why this matters on day one

The content map names managing uncertainty as a capability in its own right. Most ward decisions are made without a complete picture, and the safe practitioner is the one who says so and builds a net rather than manufacturing false certainty.

The sequence

1. 1Name the uncertainty. Write the differential, not a single guess. Record what would confirm or refute each, and what you have decided not to pursue and why.
2. 2Safety-net explicitly. What would change the plan, who acts, and by when. "Repeat lactate at 2am; if above 3, escalate to the medical registrar" is a safety net. "Monitor" is not.
3. 3Prioritise across patients. Sickest first; then time-critical (antibiotics, insulin, Parkinson's drugs, time-limited scans); then everything else. Rewrite the list when it changes rather than holding it in your head.
4. 4Handle multimorbidity. Treating each condition to guideline can harm the whole patient. NICE NG56 asks you to consider treatment burden, what matters to the patient, and where guidelines conflict. Deprescribing is a legitimate plan.
5. 5Say it out loud to the patient. "I don't yet know what is causing this, but here is what I have ruled out, here is what we are doing next, and here is what would make us act sooner." Patients tolerate uncertainty far better than they tolerate discovering it was concealed.

What goes wrong

• Committing to a diagnosis early and reading everything afterwards as confirmation.
• "Monitor" or "for review" with no parameter, threshold or owner.
• Treating every condition to its own guideline in a frail patient with eight of them.
• Hiding uncertainty from the patient to seem competent.
• Holding a changing priority list only in your head across a twelve-hour shift.
