OCR struggles with medical scans — anyone found reliable workflows?

Hello!

Testing GPT OCR with medical reports (lab values, structured tables, hospital PDFs). Works okay for simple text, but struggles with:
– tables + units
– handwritten notes
– compressed scan images

I'm currently preprocessing via phone scan apps, adjusting contrast, and splitting pages. Still not great.

Anyone here reverse-engineered a prompt/workflow combo that consistently boosts OCR accuracy for clinical docs?

Not for diagnosis, purely documentation.
