20. Advanced Simulation: Dealing with Uncertainty

Clinical Uncertainty

Clinical uncertainty is when a healthcare professional has to make a decision with incomplete, unclear or changing information.

5 Main Sources of Clinical Uncertainty

1. Incomplete information

2. Ambiguity of symptoms

3. Evolving conditions

4. Patient preferences/communication

5. Knowledge gaps

How does incomplete information cause uncertainty?

The patient may not mention all symptoms, may not know key details, or tests/results may not be available yet.

How does ambiguity of symptoms cause uncertainty?

Many conditions can present with similar symptoms, making it hard to know the true cause.

What does "evolving condition" mean?

A condition may change over time, so the patient's symptoms today may not show the full picture yet.

How can patient communication create uncertainty?

Patients may describe symptoms vaguely, minimise symptoms, forget details, feel embarrassed, or have preferences that affect the plan.

What is a knowledge gap in clinical uncertainty?

When the clinician does not know enough about a condition, guideline, medicine, or referral pathway to make a confident decision.

What is the first strategy for managing uncertainty?

Use a clinical reasoning framework: gather information systematically, rule out red flags, and use diagnostic criteria/guidelines.

What does "rule out red flags" mean?

Identify symptoms that could suggest serious disease and need urgent referral rather than OTC treatment.

What red flags would matter in a diarrhoea/bowel case?

- Blood in stool

- Unexplained weight loss

- Persistent change in bowel habit

- Severe pain

- Fever, dehydration

- Nocturnal symptoms

- Age over 50 with new symptoms

- Family history of bowel cancer.

How does shared decision-making help with uncertainty?

It allows the clinician to explain uncertainty honestly, discuss options, and involve the patient in the safest plan.

What phrase could you use when explaining uncertainty to a patient?

"I can't say for certain what is causing this today, but some features mean it needs checking by a GP rather than just treating it with an over-the-counter medicine."

When should you consult a colleague or guideline?

When the presentation is unclear, there are red flags, the treatment choice is uncertain, or the case is outside your confidence/competence.

How does managing personal bias help clinical decisions?

It prevents assumptions from narrowing your thinking too early and helps you consider serious alternative diagnoses.

Anchoring Bias

Fixing too early on one diagnosis and ignoring information that points elsewhere.

Confirmation Bias

Looking mainly for information that supports your first impression while ignoring evidence against it.

Premature Closure

Stopping the diagnostic reasoning process too early before considering other possibilities.

Why is patient safety central when dealing with uncertainty?

If there is a risk of serious harm, you should stand on the side of caution and refer/escalate.

Reflective Practice

Thinking back on clinical decisions to identify what went well, what was uncertain, and what could be improved next time.

How can reflective practice reduce future uncertainty?

It helps identify knowledge gaps, improve reasoning, and build confidence for similar cases.

What emotional effects can uncertainty have on clinicians?

Anxiety, reduced confidence, fear of missing something serious, over-referral, or over-treatment.

What professional behaviours help manage uncertainty?

Staying systematic, asking focused questions, checking guidelines, documenting reasoning, safety-netting, seeking supervision, and reflecting afterwards.

What does safety-netting mean?

Giving clear advice on what to do if symptoms worsen, persist, or red flags develop.

Key Takeaway for Dealing with Uncertainty

Uncertainty is normal in clinical practice, but it should be managed using structured reasoning, guidelines, shared decision-making, bias awareness, safety-netting and escalation when needed.
