A list of patients last seen eight months ago is worth more than any advertising budget. Most of them stopped because life got busy, and a short message at the right moment brings a meaningful share of them back.
Courses of care fall apart in the middle. Knowing who has had three of six planned visits, and who simply vanished after the second, is the difference between finishing treatment and losing the patient to a competitor.
Missed appointments are the largest avoidable loss. A reminder the day before and a clear policy recover most of the slots that would otherwise sit empty at short notice.
Notes are a professional obligation with real consequences. Written in the room rather than at the end of the day, they stay accurate and they hold up if anyone ever asks.
