Complaint Investigation Disposition: The 483 Most Teams Don't See Coming.

The Scene

Day four of the inspection.

. The investigator pulls Complaint COMP-2024-0312. A patient reported tablet appearance variation in Losartan Potassium Tablets 50 mg, Lot 2024-0623 — small white spots on some tablets in a single bottle.

The investigation team examined the retain sample. Found similar low-incidence cosmetic variation in the retain. The conclusion: cosmetic variation only, no impact on patient safety or product performance. No further action. Complaint closed.

The investigator turns to the conclusion.

Investigator
"Cosmetic only — no further action."
She reads the conclusion twice. Then she sets the file down and looks up.
Investigator
"Who authorized the no-action determination? Was the entire lot examined or only the retain sample? Were patient safety and product performance specifically evaluated through testing, or only inferred from appearance? And on what basis was extension to other lots in the campaign ruled out?"
She listens to the verbal answer. Then she asks for the documented reasoning.
Pause

Most QA teams answer this question verbally. The file does not contain the documented reasoning. That is the gap.

Why this matters now

Complaint investigations concluding no-action without documented patient safety evaluation are commonly cited in 483 observations, particularly for products with serious indications. The pattern: visual examination performed, cosmetic conclusion drawn, no documented evaluation of broader implications.

What the file contained

The complaint investigation was complete. The retain was examined. The disposition was reached.

The retain sample was examined visually. Similar low-incidence appearance variation was identified. Patient safety implications were considered. The Complaint Investigator signed the closure. The patient was sent a courtesy response.

What the file contained was the conclusion.

What the file did not contain was the decision.

A retain examination was performed. A cosmetic-only conclusion was reached. A no-action determination was authorized. But the rationale for limiting examination to the retain sample, the documented evaluation of patient safety beyond visual inspection, and the named individual who authorized the no-action determination are not in the file.

The conclusion belongs in the file. The decision belongs in the record.

What the investigator is evaluating
21 CFR 211.198 requires investigation of complaints. The standard is not whether the visual examination was performed. The standard is whether the no-action conclusion was reached on a documented basis that includes patient safety evaluation.

Under ICH Q10 and post-market surveillance expectations, the rigor required for a no-action conclusion increases when the complaint involves a tablet appearance change that could indicate formulation, manufacturing, or packaging issues affecting other lots.

The investigation must demonstrate — in writing, contemporaneous with the determination — that patient safety was evaluated beyond visual inspection, that other lots in the manufacturing campaign were considered, and that the named authorizing individual reviewed the evidence before concluding no action.

A retain visual examination is data. A retain visual examination is not, on its own, a documented complaint disposition.

Investigator
"I am not asking whether the variation was cosmetic. I am asking whether the no-action determination was authorized — and on what evidentiary basis."
The Complaint Investigator cannot produce the record.
The Gap

The complaint may have been cosmetic. The file does not show the work behind concluding no action.

The complaint file documents the closure. It does not document who decided there was no action, on what evidence, against what alternatives, and under what authority.

The 483
"Failure to document the rationale used to justify the conclusion that the complaint did not require regulatory reporting or further product action, including the specific evidence reviewed and the basis on which reportability criteria were evaluated. The complaint closure record establishes that the complaint was investigated but does not reconstruct the decision logic that produced the disposition."
21 CFR 211.198 — applied regulatory framework.
