Data control and retention for PHI is not just about compliance. It’s about truth in systems. Who holds the data? Why is it still there? What process erases it when the time comes? The wrong answer is “I don’t know.”
When PHI enters your systems, control begins with ownership. Ownership means knowing every point of entrance, every destination, and every shadow copy. Logs, caches, backups—retention policies must include them all. When you map this flow, you see where your walls are solid, and where they leak.
Retention policies are not one-size-fits-all. Some PHI must live for years. Some must vanish within days. Define these rules in code, not in documents no one reads. Automate expiry. Delete without exceptions. The longer you store unnecessary PHI, the heavier your risk load becomes.
Access control is the twin pillar of retention. Limit permissions to only what is necessary, for only as long as it’s needed. Audit every change, and treat each permission like live ammunition—tracked, logged, and revoked when done.
