Why you should hold your own medical records

People assume their medical history follows them. It does not, and the assumption causes repeated tests, missed information and avoidable risk.

Why records do not travel

• Health systems use incompatible record formats.
• Data protection rules restrict cross-border transfer.
• There is usually no legal obligation to send records abroad.
• Even within one country, private and public systems often do not share.
• Hospitals within the same city may not share.

The last two points surprise people most. The problem is not only international; it exists across the road.

What goes wrong without records

• Tests are repeated unnecessarily, including imaging with radiation.
• Previous treatment failures are unknown, so the same things are tried again.
• Allergies and adverse reactions are not known.
• Baseline values are unavailable, so changes cannot be assessed.
• Diagnosis takes longer and costs more.

The fourth point matters more than it sounds. A single abnormal result means little without knowing what your normal looks like.

What to collect

• Discharge summaries from every hospital admission.
• Operation and procedure reports.
• Pathology reports, including biopsy results.
• Imaging reports and the images themselves.
• Laboratory results with reference ranges.
• Specialist letters.
• Current medicine list.
• Allergy and adverse reaction history.
• Vaccination record.
• Implant and device documentation.

Reference ranges are essential because laboratories differ in method and units, and a number without its range can be misinterpreted.

Imaging deserves special attention

• The report is not the same as the images.
• A second opinion may require reviewing the images directly.
• Request images on physical media or by secure transfer.
• Ask what format they are supplied in.
• Check the media works before you rely on it.

The last point is practical advice learned the hard way. Discs handed over at discharge are sometimes blank or unreadable.

Requesting records

• Most jurisdictions give patients a right of access.
• The process is usually a written request.
• There may be a fee and a processing period.
• Request the complete file, not a summary.
• Specify the format you want.

Ask for the complete record. Summaries are prepared by someone deciding what matters, and their judgement may not match your needs later.

Timing matters

• Request records before leaving a country, not after.
• Requests from abroad are slower and sometimes refused.
• Records are retained for a limited period and then destroyed.
• Facilities close, merge or change systems.

The third point is underappreciated. Retention periods vary, and records from decades past may no longer exist.

Building a summary document

• One page, current, updated after significant events.
• Conditions with dates of diagnosis.
• Medicines with generic names and doses.
• Allergies with the reaction described.
• Past surgeries with dates.
• Key test results with dates.
• Treating clinicians and contact details.

Describing the reaction matters. "Allergic to penicillin" covers everything from a mild rash to anaphylaxis, and the difference changes decisions.

Generic names, not brands

• Brand names differ between countries.
• The same brand may contain different ingredients in different markets.
• Generic names are internationally standardised.
• Include dose, frequency and route.
• Note the indication where known.

The second point is a genuine hazard. Brand names are commercial property and are reused across products in different territories.

Organising the collection

• Chronological order within categories.
• Separate current from historical.
• Index at the front.
• Date everything.
• Keep originals where possible.

Digital storage

• Scan or photograph everything.
• Use a service you can access from any device.
• Name files consistently with dates.
• Keep a backup independent of one provider.
• Protect appropriately, since this is sensitive data.

Balance security against retrievability. A perfectly secured archive you cannot open in an emergency is not serving its purpose.

Translation

• Key documents benefit from professional translation.
• The summary page is the priority.
• Machine translation is acceptable as a fallback but check drug names.
• Keep the original alongside any translation.

Keeping the original matters because a clinician who reads the source language may prefer it, and because translations can introduce errors.

For children

• Birth records and any neonatal complications.
• Growth measurements over time.
• Immunisation record, often required for school.
• Developmental assessments.
• Hand over the file when they reach adulthood.

Growth curves in particular are a record that cannot be reconstructed later, and they matter for interpreting later problems.

Records for specific situations

• Cancer care generates large volumes across several specialties.
• Pregnancy records matter for future pregnancies.
• Cardiac device documentation includes settings and identifiers.
• Transplant records include matching and immunosuppression history.
• Psychiatric records carry particular sensitivity.

Cardiac device identifiers are worth carrying separately. If a device needs checking abroad, the model and serial number determine which programmer can interrogate it.

Family history is part of the record

• Conditions in parents, siblings and children.
• Ages at diagnosis where known.
• Causes of death in close relatives.
• Known genetic conditions in the family.

This information is easily lost between generations and cannot be reconstructed once relatives have died. Recording it while people are available is worth the awkward conversation.

What to do when records are lost

• Contact every facility you remember attending.
• Ask your regular doctor what they hold.
• Pharmacies may have dispensing histories.
• Insurers may hold claim records showing what was done.
• Write down what you remember, dated, as a partial substitute.

The fourth route is often overlooked and can reconstruct a surprising amount of a treatment timeline.

Maintaining the collection

• Request a copy after every significant appointment.
• Update the summary immediately, not later.
• Review annually.
• Remove superseded medicine lists to avoid confusion.

The last item prevents a dangerous failure mode: an out-of-date list handed to a clinician in an emergency.

Summary

Health systems rarely transfer records, even between hospitals in the same city, so you are the transfer mechanism. Collect complete files rather than summaries, and always request them before leaving a country. Imaging reports are not the same as images, and a second opinion often needs the images themselves. Use generic drug names, because brands differ between markets and are sometimes reused for different ingredients.
