HL7 Interface Message Failure Rate Calculator accuracy and testing

Formula source

• Failure rate = failed messages / total messages x 100. Retry rate = retried messages / total messages x 100. Triage hours = failed messages x average triage minutes / 60.

Test cases

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 transparent formulas rather than vendor-specific sizing or compliance models.
• Inputs are processed locally in the browser and are not stored by Calwarden.
• Message failures can affect patient care workflows, privacy, billing, and reporting; validate critical incidents through operational and compliance processes.

Unit handling

• Total Messages accepts numeric values.
• Failed Messages accepts numeric values.
• Retried Messages accepts numeric values.
• Average Triage Time accepts values in min/failure.
• Message Failure Rate is displayed as a percentage.
• Retry Rate is displayed as a percentage.
• Estimated Triage Time is displayed in hr.

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.
