Case study: how ClinicDirect booked 12,000 appointments with one agent
ClinicDirect runs 14 dental practices across the Nordics. In Q1 2026 they deployed a single Callable agent to handle every inbound and outbound scheduling call across the network. Over 90 days that agent booked 12,000 appointments, handled 5 languages, and maintained a 92% show-up rate — 11 percentage points higher than their previous human-only baseline. Here's what they did and what we learned.
The starting point
Before Callable, ClinicDirect ran a centralized scheduling team of six staff covering Mon-Fri 8am-6pm. After-hours and weekend calls went to voicemail. Their measured voicemail-to-booking conversion was 8%. Their show-up rate on bookings made during peak phone hours was 81%.
Two problems were obvious: the after-hours gap, and the show-up rate. Both were symptoms of the same root cause — scheduling staff under load and unable to do the consistent confirmation and reminder work that drives attendance.
What we built
The deployment uses a single agent persona (a friendly mid-range female voice named Linnea) across all 14 practices, with practice-specific knowledge injected per call. The agent handles inbound scheduling, outbound confirmation calls 48 hours before each appointment, and a reactivation campaign for patients who hadn't booked a check-up in over a year.
Calls run in Swedish, Norwegian, Danish, English and Finnish, with the agent auto-detecting language from the first two seconds of speech and switching mid-call if the caller does.
The numbers after 90 days
The most important metrics from the first quarter of running fully on Callable:
- 12,043 appointments booked across the network.
- 92% show-up rate on appointments booked by the agent (vs 81% baseline).
- 31% of bookings placed outside the previous 8am-6pm window.
- Average call length: 2m 14s (vs 3m 41s for human staff on equivalent calls).
- Zero increase in patient complaints to the central support line.
What worked
The biggest single contributor to the show-up jump was the automated 48-hour confirmation call. Human staff had been doing this inconsistently; the agent does it for 100% of bookings, in the patient's preferred language, at a time of day they're statistically likely to answer. That alone moved show-up by an estimated 7 points.
The second-biggest contributor was after-hours availability. A meaningful chunk of bookings came in between 7pm and 11pm — exactly when the human team was unavailable.
What we'd change
Two things to do differently next time. First, we underestimated how often patients want to reschedule, not book new — the initial prompt didn't handle 'I need to move my Tuesday appointment' gracefully and was tightened in week three. Second, the reactivation campaign produced great booking numbers but lower show-up; long-dormant patients need a different confirmation cadence than fresh bookings.
Both are now part of the default Callable scheduling template, so the next clinic team to deploy gets these fixes for free.
