Track callback activity
- •Log time spent returning voicemails and missed calls.
- •Tag callbacks by type (voicemail, missed call, referral, etc.).
- •Measure callback success rate (reached vs. left another message).
Operations KPI•Staffing efficiency
Callback Burden
Measures how much staff time is spent returning calls instead of handling live interactions.
This KPI quantifies the hidden cost of voicemail and missed calls. It shows how many hours per week staff spend on callbacks, helping leaders justify automation to reduce rework.
Expressed as hours per week spent on callbacks and average callbacks per staff FTE.
Average callback load
6–12 hrs/week per FTE
Varies by call volume and staffing levels.
Peak callback times
Morning + after lunch
Callbacks cluster when staff return messages.
Cost breakdown
“Show your work” table
| Line item | Annual spend | Per-unit | Notes |
|---|---|---|---|
| Voicemail callbacks | 8.5 hrs/week | Per FTE | Returning messages left overnight or during peaks. |
| Missed-call follow-ups | 3.2 hrs/week | Per FTE | Calling back patients who abandoned during hold times. |
| Referral clarifications | 2.1 hrs/week | Per FTE | Chasing missing information from referring offices. |
Calculate opportunity cost
- •Multiply callback hours by fully loaded staff cost.
- •Compare to cost of AI answering those calls initially.
- •Factor in lost revenue from callbacks that never reach patients.
Assumptions
What this KPI assumes
Time tracking
Based on staff-reported callback time and call logs.
Callback success
Assumes 65–75% of callbacks reach the patient.
Staff cost
Uses fully loaded cost including benefits and overhead.
