Reduce no-shows at your vet clinic — evidence-based, messaging-first
Published May 3, 2026 · 7 min read
Average no-show rate in healthcare: 23%. JAVMA study: 34.2% of clients didn’t return for post-surgical follow-up. Every empty slot = lost revenue + idle staff.
The simplest fix: two reminders (48h + day-of) via messaging app — reduces no-shows by ~25% per BMJ meta-analysis.
Strategies ranked by evidence
| Strategy | Evidence | Effect | Difficulty |

| 2× text/chat reminder | High | ~25% relative reduction | Low |
| Reminder + confirm/cancel | Moderate | Better than plain reminder | Low-Med |
| Phone call for high-value cases | Moderate | OR 1.8 | High |
| Deposit for surgery/new clients | Moderate | 79% of clinics report effectiveness | Med |
| Walk-in buffer slots | Moderate | Doesn’t reduce no-shows but recovers capacity | Med |

No-show cost formula
Annual loss = Slots/day × Days/year × No-show rate × Revenue/visit × % slots unfilled
Example: 15 × 300 × 10% × $25 × 60% = $6,750/year for a small clinic.
Practice management software like VetGo automates reminders via Zalo/LINE/WhatsApp — 48h + day-of, with confirm/reschedule buttons, tracking no-show rate over time.
