What's the difference between SMS and email reminders for a physio practice?

SMS has a 98% open rate vs 20% for email. SMS is read within 3 minutes on average vs 2.5 hours for email. For medical appointment reminders, SMS is significantly more effective.

What no-show reduction can be expected with automated SMS?

The observed average in physiotherapy practices is 25-40% reduction depending on the setup. A D-2 reminder plus a D-0 reminder is the most effective combination.

How should annulled slots be managed?

An early cancellation lets you offer the slot to a waiting list patient. The system should automatically send the freed slot to the first 3 patients on the waiting list.

What's the expected ROI for a 2-practitioner physio practice?

For a 2-practitioner practice with 9% no-show rate: system cost 35 EUR/month, revenue recovered 1,980 EUR/month. ROI: 5,657%.

Level 1: D-2 Reminder (48h before) - Most effective alone. "Your physio session is on [Day] at [Time]. Reply YES to confirm or NO to cancel." Average: 78% reply YES. No-show reduction: -25%.

Level 2: D-0 Reminder (2h before) - For non-respondents (22%). Additional -15% no-shows. Combined D-2 + D-0: -35 to -40% no-shows.

Level 3: Automatic Waiting List - When a patient cancels, system sends SMS to first 3 on waiting list. First YES gets the slot. Slot replacement rate: 60-75%. Gartner (2024): practices with automated waiting lists recover 68% of potentially lost revenue.
