This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests whether simple nudges—like text message reminders for patients and automatic mammogram orders for doctors—can increase breast cancer screening among women aged 40 to 74 who are overdue for a mammogram. The trial involves over 21,000 women at two health systems. Some participants receive text reminders to schedule their mammogram, while their doctors get a pre-filled order in the electronic health record. The goal is to see if these gentle pushes help more women complete screening within three to six months.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
text message reminders and electronic health record prompts
What this could lead to
If successful, this approach could provide a simple, scalable way to boost breast cancer screening rates, catching cancers earlier and saving lives.
What could go wrong
The trial tests behavioral nudges, not a new medical treatment, so the impact may be modest. Results depend on how well patients and clinicians respond to reminders, and may not apply to all healthcare settings.
