Background:
Our objective was to characterize individual-level screening patterns during a fourteen-year period spanning changing breast cancer screening guidelines and the COVID-19 pandemic.
Methods:
We conducted a retrospective analysis of mammography screening in women ages 40 years and older using 2010 to 2023 data from the Vermont Health Care Uniform Reporting and Evaluation System, a statewide all-payer insurance claims database.
Results:
Biennial mammography screening adherence declined between 2010 to 2023 by 20.7 and 6.7 percentage points for women ages 40 to 49 and 50 to 74 years, respectively. Younger birth cohorts consistently had lower screening rates at any given age compared with older cohorts. Cohorts under age 50 years during the COVID-19 pandemic have had the largest postpandemic recoveries, with postpandemic screening rates exceeding prepandemic screening adherence.
Conclusions:
Whereas mammography screening rates have been declining both between and within birth cohorts, pandemic disruptions have narrowed the gaps resulting from these trends.
Impact:
Sustaining postpandemic screening momentum may be critical to reversing long-term declines in adherence.
