No-shows are the most solvable revenue leak in clinical practice.
Why patients no-show (real data)
- Forgot — 42%
- Felt better — 18%
- Couldn't leave work — 15%
- Traffic / weather — 11%
- Family / childcare — 8%
- Bad past experience — 6%
60% of no-shows are simply forgetfulness. A reminder solves them.
The two-stage reminder protocol
- 24 hours before: full message with patient name, doctor, time, address, reschedule link. Sent at 6-8pm for highest open rates.
- 2 hours before: short reminder with clinic phone number. Sent on the day of appointment.
Skip a third reminder. It pushes confirmation rates marginally up but review sentiment markedly down.
WhatsApp vs SMS vs phone
- WhatsApp open rate: ~98%
- SMS open rate: ~20%
- Phone call answer rate: ~35%
WhatsApp wins by every metric. Plus patients can reply to reschedule, which a one-way SMS or call can't capture.
For high-value slots: deposit-based booking
Specialty consultation, premium time slot, or known repeat-no-show patient: require a ₹100-₹200 confirmation deposit. Cuts no-shows under 2% for that segment.
Tracking
Measure the right metric: no-show percentage = no-shows ÷ booked. Should drop from ~20% to ~7% within 4 weeks of turning on automation.
