How do you calculate a compliance documentation risk priority number?

Multiply severity by occurrence by detection, each scored 1-10. The default 7 x 3 x 5 yields the displayed score; the higher the product, the more urgent the documentation gap.

What is a good RPN for documentation risk?

There is no universal threshold, but teams commonly set an action line (for example, RPN above 100 on a raw 1-1000 scale) and always act on any gap with a severity of 9 or 10 regardless of total.

What counts as a documentation gap for hospital equipment?

Missing or unsigned device history records, an outdated device master record, absent calibration or torque traceability, or incomplete biocompatibility and labeling files for a clinical product.

Why score detection separately?

A severe, frequent gap that your review process always catches is lower risk than a subtle one that escapes to the field. Detection captures whether your controls would stop the gap before release.

Severity vs occurrence in compliance scoring?

Severity is how bad the consequence is if the gap reaches an auditor or patient; occurrence is how frequently the gap actually happens. A rare but catastrophic gap and a frequent but minor one can score very differently.

How do I reduce a documentation RPN?

You usually cannot change severity, so lower occurrence (better templates and training) or improve detection (electronic DHR checks, mandatory sign-off gates). Both pull the product down.

Hospital Equipment & Clinical Furniture calculator

Compliance Documentation Calculator

Compliance Documentation risk scoring applies FMEA-style thinking to the paperwork that keeps hospital equipment and clinical furniture legal to sell. For a regulated medical device, a missing torque record, an unsigned device history record (DHR) line, or an out-of-date device master record (DMR) can be as damaging as a physical defect, triggering audit findings, holds or recalls. Quality and regulatory staff multiply the severity of a gap, how often it occurs, and how likely it is to slip through to produce a risk priority number that ranks documentation weaknesses for remediation. It turns a vague sense that the paperwork is shaky into a prioritized, defensible action list.

What this calculator does

Score the risk of a compliance documentation gap for hospital equipment by rating severity, occurrence, and detection to produce a risk priority number for quality and regulatory reviews.
Use it when prioritizing compliance documentation gaps during an internal audit, a 510(k) submission review, or an ISO 13485 surveillance audit preparation cycle.
It computes a risk priority number for a compliance documentation gap by multiplying its severity, occurrence and detection scores on a consistent 1-10 scale.

Formula used

Compliance documentation risk priority number = severity × occurrence × detection
Use the same 1 to 10 scale consistently across all compliance documentation gaps being ranked.

Inputs explained

Severity if this documentation gap surfaces in audit or the field:
How often this documentation gap occurs:
Ability to catch the gap before release:

How to use the result

Use it when triaging documentation findings before an FDA, ISO 13485 or notified-body audit, or when building a quality-system improvement backlog.
Multiplicative RPNs treat different score combinations as equal: a 7x3x5 and a 5x3x7 both rank near the same total even though a high-severity gap usually deserves priority regardless of detection.

Current U.S. benchmarks

The producer price index for lumber and wood products stands at 280.994 (BLS, May 2026), up 4.2% from a year earlier. Quotes priced off last quarter's material cost miss this move.
U.S. manufacturing runs at 75.6% of capacity with new factory orders at $657B per month (Federal Reserve and Census, May 2026).
Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
The U.S. has 14,378 furniture and related products establishments employing about 355,594 workers (Census County Business Patterns, 2023).
