Ask whether you need reassessment now
Explain what has changed and ask what care you need now. Bring a short timeline of symptoms, visits, tests, and messages.
Understand the situation
What may help answer the question
Describe the course of the problem
Explain when symptoms began, how they changed, how they affect daily life, and what other care you received. A short account helps the team understand your concern and identify missing information.

Ask what remains possible
Several conditions can cause similar symptoms. Ask which explanations are being considered, what supports the working diagnosis, and what the examination or tests can and cannot establish. A possibility is not a confirmed diagnosis.

Review what was known at each visit
Diagnostic-safety review considers the information available at the time and how the assessment evolved. A later diagnosis or worsening condition alone does not establish that an earlier opportunity was missed. Ask what the earlier findings supported and what changed.

Leave with a follow-up plan
Ask what happens next, when to return, and which changes require earlier contact. Tell the team if you cannot obtain a test, attend a referral, or follow the instructions. Confirm who will help resolve that barrier.

Keep current safety separate from a review
Do not delay emergency care while collecting records or asking about earlier decisions. Call 911 for a suspected medical emergency, such as severe breathing difficulty or loss of consciousness.

Terms in ordinary language
- Differential diagnosis
- Possible explanations the clinician is comparing.
- Working diagnosis
- The current explanation guiding care while assessment continues.
- Return precautions
- Instructions about changes that should prompt contact with the team or urgent care.
This guide cannot determine whether a diagnosis was negligent or whether an earlier decision caused harm. A review needs the clinical context at each stage. Patient questions support communication; responsibility for safe diagnostic care does not shift to the patient.
Prepare for a conversation
Questions to put in writing
- 1What is the current explanation, and what remains uncertain?
- 2Which other possibilities matter, and what makes them more or less likely?
- 3What did the examination and tests establish, and what could they not answer?
- 4What change would require reassessment, and whom should I contact?
- 5Which tests or referrals remain outstanding, and who will review their results?
Useful information
Records that may help
Ask for relevant existing material. Not every item will exist or be available through the same process.
- Dated visit and examination notes
- Test reports and usable copies of existing images
- Patient-facing messages and documented contact notes, when available
- Referral, discharge, and follow-up instructions
Choose a next step
Practical next steps
- 1
Address current symptoms and clarify the next clinical step.
- 2
Build a short timeline, keeping your recollection separate from dated records.
- 3
Ask the treating team to explain changes in the assessment and any outstanding actions.
- 4
Consider another qualified clinical evaluation when it would help and delay is safe.
