First seen Jun 25, 2026 · Last updated Aug 13, 2026 · Updated 3 times
Summary
This study tests whether sending text message reminders to patients and alerts to doctors can increase the number of women who get their recommended mammograms. About 8,490 women aged 40-74 who are overdue for screening will take part. The goal is to see if these simple 'nudges' help more women complete their mammogram within 3 to 6 months after a primary care visit.
