What the prompt labels mean

The person didn't share their exact words, so we wrote this from what they described. We haven't tested it, and they didn't use this exact version.

I've uploaded 145 pages of ICU medical records for a family member. I'm not a doctor. Explain the key test results in plain language, build a timeline of what has happened so far, and summarize what the hospital plans to do next. I'll add new records every day, so update the report each time.

Optional stronger version

Our rewrite with extra checks. The poster didn't test it.

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Turn a family member's hospital records into a plain-language daily report I can check, without misreading any result.

Questions to ask me first:
- What is the patient's main problem, and how long have they been in the hospital?
- Which records do you have (labs, notes, imaging), and how often do new ones arrive?
- Who in the family will read the report?

Inputs (fill in or confirm):
- Records: [UPLOAD PDFS OR TEXT]
- Patient's main problem: [PROBLEM]
- Questions the family has: [QUESTIONS]

Rules:
- For every result you call abnormal or significant, quote the exact line and the result column, and never treat a reference range column as a result.
- Separate what the records say from your own interpretation.
- Keep a dated timeline and note what changed since the last report.
- Don't suggest treatments; list questions for the care team instead.

Checkpoint: After the first report, list every finding you flagged as significant with its quoted line so I can check them against the originals.

If you get stuck: If the records are too long to read at once, tell me which pages you covered and ask for the rest instead of guessing.

Verify before you finish: Recheck each flagged finding against the original lab line before you finish.

Output: A one-page daily report: key results with quoted lines, a timeline, what the hospital plans next and questions for the care team.

Done when: The family has a report every flagged finding in which matches the original record.

Outcome

While a family member was in the ICU, Ryan Cohn uploaded 145 pages of ICU medical records to Claude and used it to build a clinical analysis report, updated daily, with key test results, a timeline and what the hospital planned next. It helped Cohn follow what the care team was saying and kept the family informed. Claude also caught an infection buried in the records; it prompted an extra test that ruled something out. But Claude also flagged Trichuris trichiura parasite eggs as a significant finding when the lab result read 'No Parasites Found.' It had confused the reference range column, which lists what the test looks for, with a positive result. Cohn caught the error by checking the original record.

Evidence: Described by posterThe person describes what happened in words, without screenshots or video.

Known limitations

PartialThe source says it only partly worked, or had a significant problem a person had to deal with.

What went wrong: Claude misread a negative parasite test as a significant finding, which Cohn caught only by checking the source. Cohn hit Claude's memory limit several times.

Context: The patient portal lagged about 24 hours, so the report always trailed the care team. Cohn says none of this replaced a doctor.
