Appointment No-Show Rate
The percentage of eligible scheduled appointments where the scheduled attendee did not attend and did not cancel within the defined policy window.
Business question
What share of eligible scheduled appointments is recorded as a no-show under the agreed attendance policy?
Formula
Appointment no-show rate = eligible scheduled appointments recorded as no-shows under the policy ÷ eligible scheduled appointments × 100.
Calculation notes
Define the policy window, appointment eligibility, attendance event, rescheduling treatment, walk-in treatment, and the handling of provider-caused cancellations before comparing periods.
Edge-case guidance
Do not classify a late cancellation as a no-show unless the documented policy does so. Keep emergency, overbooked, and documented exception categories separate and aggregate.

Interpretation
Use this aggregate operational measure to understand unused scheduled capacity. Keep late cancellations, rescheduled appointments, walk-ins, provider-caused cancellations, and documented scheduling exceptions separate.
Caution
Use aggregate records only. Do not include names, individual record identifiers, or other personal health information. Implementation must follow applicable privacy, healthcare, and insurance requirements. Exclude records that cannot be classified consistently.
Implementation recommendation
Agree on aggregate status definitions and the policy window with scheduling owners, then annotate changes in booking policy and capacity.
Target guidance
Set a context-specific target for appointment no-show rate from comparable historical periods, then adjust it for scheduling policy, operating capacity, seasonality, service mix, and data quality. Review the target with the accountable operations owner; reducing it through punitive or exclusionary scheduling practices may distort access and the measure.
