PHI Exposure Risk Scoring 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

  • Risk score = weighted sum of volume, sensitivity, recipient risk, acquisition likelihood, and inverse mitigation on a 0-100 scale.

Test cases

Default input regression check

Generated from the checked-in default inputs and calculate function.

Inputs

  • Records Exposed: 500
  • Data Sensitivity: 7
  • Recipient Risk: 6
  • Acquisition Likelihood: 5
  • Mitigation Effectiveness: 6

Expected outputs

  • PHI Exposure Risk Score: 59.5
  • Planning Signal: Moderate planning risk
  • Volume Factor: 67.50%
  • Mitigation Credit: 60.00%

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 because healthcare policy, prices, retention requirements, and incident facts vary.
  • Calculations run locally in your browser and do not store PHI, incident details, access logs, system names, or operating assumptions.
  • This score is not a HIPAA breach determination and does not replace the required fact-specific risk assessment.

Unit handling

  • Records Exposed accepts numeric values.
  • Data Sensitivity accepts numeric values.
  • Recipient Risk accepts numeric values.
  • Acquisition Likelihood accepts numeric values.
  • Mitigation Effectiveness accepts numeric values.
  • Volume Factor is displayed as a percentage.
  • Mitigation Credit is displayed as a percentage.

Rounding rules

  • Number displays use up to 2 decimal places in the calculator UI.
  • Percent outputs are displayed with two decimal places.
  • Input precision follows configured step values where provided.
