Active patient

An active patient is one who has been seen by the practice within a defined recent window (most practices use somewhere between 18 and 24 months) as opposed to a patient who is technically still in the system but has not been in the office in years. The distinction matters because a chart in the software is not the same thing as a relationship the practice can actually count on for future revenue.

The active patient count is the real base a practice is working from day to day, and it is a more honest number than total patients of record, which almost always includes years of names who have moved, changed insurance, or quietly switched to another dentist without telling anyone. Tracking active count over time also reveals attrition before it becomes obvious in the schedule: a shrinking active base with a stable new patient count means the bucket has a leak somewhere upstream.

Define the window once, apply it consistently, and review the active count alongside the reappointment rate and patient attrition: together they tell you whether the recall system is actually keeping the patients the practice already has, not just adding new ones on top.
