Medical Device Patch Priority Calculator accuracy and testing
This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.
Formula source
- Priority score = severity points + exploit points + clinical criticality points + exposure points + overdue points - compensating control credit, clamped from 0 to 100.
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Severity Score: 8.2
- Known Exploit: Yes
- Clinical Criticality: 8
- Network Exposure: 7
- Days Past Patch Target: 14 days
- Compensating Controls: 40%
Expected outputs
- Patch Priority Score: 73.97
- Priority Level: High priority
- Suggested Review Window: 72 hr
- Control Credit: 10
Known limitations
- This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
- Use the result as a planning estimate unless the calculator page states a stricter purpose.
Assumptions
- Inputs are user-entered and processed locally in the browser.
- The calculator uses transparent deterministic formulas rather than vendor-specific risk, compliance, or availability models.
- Validate outputs against local policy, contracts, audit evidence, clinical safety requirements, and compliance obligations before taking action.
Unit handling
- Severity Score accepts numeric values.
- Known Exploit accepts Yes/No values.
- Clinical Criticality accepts numeric values.
- Network Exposure accepts numeric values.
- Days Past Patch Target accepts values in days.
- Compensating Controls accepts values in %.
- Suggested Review Window is displayed in hr.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
- Input precision follows configured step values where provided.
