ParanoiaIQ — Complaint Investigation Tool Preview

Overview

Seven regulatory tools. One complaint. 30 seconds.

The Complaint Investigation Tool runs a complete regulatory assessment every time a complaint is submitted. No checklists, no manual lookups. The tool applies the same framework a seasoned regulatory professional would apply — and surfaces the decision with the supporting rationale.

MDR Reportability

Evaluates reportable vs. needs-review vs. not reportable under 21 CFR 803.50, with specific basis for the determination.

21 CFR 803.50

Deadline Calculation

Calculates the 30-day (or 5-day) filing deadline from date of awareness, with days-remaining alert and overdue flag.

21 CFR 803.50(b)

Risk Score

Probability × Severity scoring on a 5×5 matrix. Classifies risk level and adjusts for service life, recurrence potential, and patient harm.

ISO 14971:2019

Investigation Required?

Determines whether a formal investigation is required (vs. complaint closure without investigation) with regulatory basis.

ISO 13485 §8.2.2

Trending Signal Check

Checks complaint history against 30-day and 12-month frequency to detect trending signals requiring escalation.

ISO 13485 §8.4

CAPA Assessment

Determines whether CAPA is required based on risk level, trending, recurrence pattern, and regulatory triggers.

ISO 13485 §8.5.2

Investigation Plan

Generates a prioritized, step-by-step investigation plan with task owner assignments and regulatory references for each step.

Step 1 (alternate) — AI-assisted entry

Paste a raw complaint narrative — the AI fills the form

When complaint text arrives as a paragraph — from a phone call, email, or MDR narrative — paste it directly. The AI extraction engine reads it and pre-fills all structured fields with confidence ratings. Reviewer confirms before running the investigation.

How AI Extraction Works

Claude reads the raw complaint narrative and extracts every field needed for the regulatory investigation — patient outcome, malfunction flag, product details, reporter type, implant status, and a condensed event description.

Confidence Ratings

✓ CONFIDENT — clear in text

~ VERIFY — plausible

! CHECK — uncertain

Note: "Fails Specification" is never auto-checked. It requires investigation to confirm — the tool flags it as uncertain and leaves it for the reviewer to determine after physical analysis.

Paste any complaint narrative — MDR report, phone call notes, email from distributor. AI extracts and confidence-rates every field. Reviewer can edit anything before running the full investigation.

Investigation Summary

This complaint involves a structural failure of a TitanSpine Lumbar Fusion System (TLF-4022) retrieved during revision surgery from a 58-year-old male patient 8.5 years post-implant. The device exhibited cracking along the superior endplate, associated with worsening radiculopathy requiring surgical intervention. The patient outcome is classified as serious injury.

MDR Reportability

This event meets the definition of an MDR-reportable event under 21 CFR 803.50(a)(2). A marketed implantable device malfunctioned, the malfunction contributed directly to serious patient injury (revision surgery), and if the malfunction were to recur, it would likely cause or contribute to serious injury or death. The 30-day reporting deadline is May 10, 2026. Filing should not be delayed pending completion of failure analysis — the regulatory clock runs from the date of awareness.

Risk Assessment

Risk was scored at 16/25 (HIGH) using ISO 14971:2019 §6 criteria. Severity is rated 4/5 — serious injury with required surgical intervention in an implantable device. Probability is rated 4/5 — 11 similar complaints in 12 months indicates a non-isolated, recurrent failure mode. The device was 8.5 years into a 10-year labeled service life (85% consumed), which is classified as approaching end-of-life rather than premature failure — relevant context for root cause framing but does not diminish the risk classification.

Trending Signal

The combination of 3 complaints in 30 days and 11 in 12 months for this specific model constitutes a statistically meaningful signal requiring formal trending evaluation. This is not an isolated complaint — it is a data point in an emerging pattern. A trending analysis covering all TLF-4022 structural failure complaints over 24 months should be initiated in parallel with the individual complaint investigation.

CAPA Requirement

A formal CAPA is required. A HIGH risk score, confirmed trending signal, and implant structural failure mode satisfy the threshold for systemic corrective action under ISO 13485:2016 §8.5.2. The CAPA scope should encompass: root cause of the structural failure mode, review of manufacturing process parameters for this lot and adjacent lots, and evaluation of whether a field safety corrective action is warranted.

ParanoiaIQ — What This Means

MDR Reportable. 30-day clock is running from date of awareness.

This complaint triggered an MDR reportable determination. The 30-day deadline is firm — it runs from the date your organization became aware of the event, not from the completion of investigation. FDA does not require the investigation to be complete before filing; it requires you to submit what you know. Filing late — or failing to file — is a primary driver of FDA warning letters in complaint handling.

If FDA reviews this complaint record later, the question they will ask is not "did you investigate?" It is: "When did you know, and when did you report?" The investigation record has to answer that question credibly.

Option 1 — Handle Internally

Proceed with internal RA/QA team. Requires: MDR competency, complaint handling SOP in place, CAPA system with documented systemic corrective action. Timeline: 2–4 weeks to compliant closure, assuming resources are available now.

Option 2 — CAPA Reset Sprint

Engage ParanoiaIQ for a focused sprint: MDR filing support, investigation plan execution, CAPA structure, and trending analysis. Typical engagement: 3–5 days. Deadline: May 10, 2026.
