The Letter That Brought Them Back

A breast imaging facility with a consistent monthly mammography volume believed something straightforward: some of their patients were overdue for routine screening and simply hadn't been asked to come back. They hadn't transferred care. They hadn't formally declined. They had lapsed — gotten busy, let a year slide into two, not received anything from the facility that prompted them to schedule.

The imaging director had a specific idea about how to address this, and it wasn't a generic reminder generated by a software system. She wrote the letter herself. It was a personal appeal, in the facility's own voice, emphasizing what routine screening is for and why returning matters. It was the kind of communication that reads like it came from a person — because it did.

Mammologix identified the patient population: women who had not returned within six months after the date they had been recommended to come back for their annual screening mammogram. That group became the target for the first mailing.

More than 25% of the patients who received the first letter returned for screening.

That was not a trial. It was the beginning of an ongoing program. The facility continued sending the letter on a routine basis as new patients crossed the overdue threshold. In subsequent mailings, approximately 15% to 20% of contacted patients returned — a sustained response rate over time, not a one-time spike.

The mechanics behind it were straightforward. Mammologix used the facility's existing patient tracking data to identify who was overdue and when, formatted and produced the mailing using the director's letter, and ran the outreach as a recurring operational workflow rather than a one-time campaign.

The cost of the program was low relative to what it produced. Each returned patient represented a completed screening mammogram — and, in some cases, a reestablished care relationship that continued beyond that first return visit.

This was not a complicated intervention. It was a well-timed, well-worded communication sent to the right patients at the right moment, supported by tracking data that made it possible to identify them precisely.

Some patients lapse because nothing prompted them to return. A single letter, written by someone who cared about the answer, was enough to change that for more than one in four.
