Managing a Family's Medical Records Without an EHR

In Mexico, electronic health records mostly don’t exist outside a handful of private hospital chains. Every visit produces a paper prescription or a printed lab report, and nothing connects one to the next. If you’re the family member managing care for someone else (an aging parent, a relative with a chronic condition), that gap becomes your job: the medication list lives in your head, the lab history in a drawer somewhere, and “who prescribed what, and how do I reach them” in whatever photo you happened to take at the time.

In healthcare, this typically means addressing the 18 identifiers specified under HIPAA’s Safe Harbor provision, or demonstrating through Expert Determination that re-identification risk is “very small.” The practical payoff: properly de-identified data is no longer considered PHI under HIPAA. That means: ...
