Radiology Backlog 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

  • Days to clear = pending studies / (daily finalization capacity - new studies per day).

Test cases

Default input regression check

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

Inputs

  • Pending Studies: 900
  • Daily Finalization Capacity: 420
  • New Studies per Day: 360
  • Weekend Coverage: 50%

Expected outputs

  • Days to Clear Backlog: 15 days
  • Net Daily Clearance: 60 studies/day
  • Backlog Days at Capacity: 2.14 days
  • Coverage Signal: Weekend coverage included

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

  • The calculators use simple transparent formulas rather than vendor-specific analytics models.
  • Inputs are processed locally in the browser and are not stored by Calwarden.
  • This is operations planning math, not medical, legal, staffing, billing, or financial advice.

Unit handling

  • Pending Studies accepts numeric values.
  • Daily Finalization Capacity accepts numeric values.
  • New Studies per Day accepts numeric values.
  • Weekend Coverage accepts values in %.
  • Days to Clear Backlog is displayed in days.
  • Net Daily Clearance is displayed in studies/day.
  • Backlog Days at Capacity is displayed in days.

Rounding rules

  • Number displays use up to 2 decimal places in the calculator UI.
  • Input precision follows configured step values where provided.
