How to Prepare a Medical Chronology Without Losing the Source Page

A step-by-step workflow for registering records, handling OCR, drafting events, preserving page locators, and reviewing the final chronology.

Short answer

Prepare a medical chronology by inventorying the authorized record, preserving immutable originals, assigning page-level coverage states, drafting one source-pinned event at a time, and requiring named human review before export. Never let a summary detach from the page that supports it.

Key takeaways

  • Start with a complete file and page inventory, not an empty timeline template.
  • Treat unreadable or uncertain OCR as a blocking gap, not a blank page.
  • Version edits and retain the reviewer and source record for the exported artifact.

Editorial methods are identified as such. Numbered links beside a paragraph or section point to the authority or framework relevant to that claim; a source does not certify Under Seal or replace current jurisdiction-specific review.

1. Define the authorized record

Basis: editorial method

Record the matter identifier, supervising attorney, primary reviewer, authorized file set, and start time. Hash or otherwise fingerprint the originals and preserve them read-only. The inventory should state the expected and observed page count for every file.

Do not mix unrelated matters or convenience copies into one index. Matter isolation is both a confidentiality control and a retrieval-quality control.

2. Create page-level coverage

Basis: editorial method

Extract native text where it exists and use an approved local OCR path for image-only pages. Assign each page a usable, needs-review, or unreadable state. Stamps, low-contrast faxes, rotations, tables, and handwriting deserve their own test cases because a single average OCR score hides the documents most likely to matter.

3. Draft atomic events

Basis: editorial method

Write one event per material occurrence. Preserve uncertainty in the wording. Attach the document and page before presenting the event as record-supported. If the date is inferred rather than stated, mark it as proposed or unresolved instead of silently turning it into fact.

  • Use concise factual wording
  • Separate symptoms, assessment, treatment, and later interpretation
  • Keep conflicting versions as reviewable conflicts
  • Do not use a citation merely because it is adjacent to the event

4. Review beside the source

Basis: editorial method

The reviewer should accept, edit, reject, or mark not found while viewing the source page. An edit creates a new version. Before export, verify that every accepted factual line has usable support and that held pages have not been used as silent evidence.
