Many practices can identify patients who are overdue under their own preventive-care or recall rules. Whether that list is available directly in the EHR, through a report, or through an approved API depends on the system and configuration.
Recall can be less expensive than acquiring a new patient because the practice already has a relationship and contact information. It still has costs: staff review, software, messages, integration, opt-out handling, and follow-up capacity.
If recall happens only when the schedule looks thin, eligible patients can be identified late or inconsistently.
The math
Use a scenario, not a benchmark. If a practice has 1,500 active patients, finds 300 who meet its overdue criteria, and 20% book after outreach, that would produce 60 appointments. The 300-patient count and 20% booking rate are assumptions; replace them with the practice's measured values before making an investment decision.
The automation
A continuous system rather than a periodic campaign. It queries your EHR on a schedule, identifies patients who just crossed the 12-month mark, and adds them to a sequence.
A possible sequence might use an initial message, one follow-up, and then a lower-frequency path. The timing, channel, number of attempts, consent or opt-out handling, and clinical eligibility should follow the practice's policies and applicable communication rules. Remove a patient as soon as they book or opt out.
A direct booking link can remove a step when the scheduling system supports the right appointment types and guardrails. Keep a phone or staff-assisted option for patients who cannot use it.
Evaluate the EHR's built-in recall tools first. Compare list criteria, communication controls, booking integration, reporting, security, and total cost. Build a custom workflow only when a documented gap justifies the additional implementation and maintenance.
