Margin notes

What is the most effective way to reduce no-shows?+
The single most cost-effective intervention is automated SMS reminders. A 2019 JMIR meta-analysis of 14 studies found SMS reminders reduce no-shows by 28-38%. Adding two-way confirmation increases effectiveness by 15%. Combined with a credit card hold at booking, practices typically achieve 50-65% total reduction.
Does telehealth reduce no-shows?+
Yes, significantly for behavioral health. A 2021 JMIR study found telehealth options reduce behavioral health no-shows by approximately 25%, particularly for patients with transportation barriers, social anxiety, and rural areas. The effect is smaller but still positive for general primary care.
Are cancellation fees and deposits legal?+
Yes, in all US states. Cancellation fees and deposits constitute valid service agreements. Best practices: disclose clearly before booking, obtain explicit acknowledgment, and apply consistently. For healthcare, fees are permitted but cannot be charged to Medicare/Medicaid patients as a condition of continued care.
How much do SMS reminders cost vs. how much do they save?+
Reminder platforms cost $50-$300/month. A business losing $50,000/year to no-shows that achieves a 33% reduction saves $16,500/year. Against a $1,200/year platform cost, that is a 1,275% ROI. For most businesses, SMS reminders pay for themselves within 2-4 weeks.
