This study characterized individual-level trends in mammography screening over a fourteen-year period (2010–2023) that encompassed evolving breast cancer screening guidelines and the COVID-19 pandemic. The analysis addressed changes in adherence to biennial screening across age groups and birth cohorts to better understand long-term patterns in early detection efforts.
Authors conducted a retrospective analysis using data from the Vermont Health Care Uniform Reporting and Evaluation System, a statewide all-payer claims database. The analytic population was women aged 40 years and older. The study period covered 2010 through 2023, allowing assessment of screening patterns before, during, and after the COVID-19 pandemic. The primary outcome reported was adherence to biennial mammography screening over time. The abstract provides these high-level methods; additional methodological specifics (for example, inclusion/exclusion criteria, statistical models, and adjustment variables) were not detailed in the provided source material.
The study found declines in adherence to biennial mammography screening between 2010 and 2023. Specifically, adherence decreased by 20.7 percentage points among women aged 40 to 49 years and by 6.7 percentage points among women aged 50 to 74 years over the study period. These numerical results were provided in the abstract as the primary quantitative outcomes describing temporal declines.
Analyses by birth cohort revealed that younger cohorts consistently had lower screening rates at a given age compared with older cohorts. This pattern indicates both between-cohort differences (younger cohorts are less likely to screen than older cohorts when compared at the same age) and within-cohort declines over time. The abstract highlights these cohort effects as an important contributor to long-term decreases in screening adherence.
The COVID-19 pandemic caused disruptions in routine health services, including breast cancer screening. In this analysis, cohorts who were under age 50 during the pandemic showed the largest postpandemic recoveries in screening. For these younger cohorts, postpandemic screening rates exceeded prepandemic screening adherence. The authors interpret this finding to mean that pandemic-era interruptions narrowed the gaps produced by long-term declining trends in screening.
The authors conclude that mammography screening rates have been declining both between birth cohorts and within cohorts over time. However, pandemic-related disruptions were associated with a narrowing of gaps in screening adherence, particularly among women under 50 during the pandemic who experienced pronounced postpandemic recoveries. The authors emphasize that sustaining postpandemic screening momentum may be critical to reversing long-term declines in adherence to mammography.
Clinically, these findings suggest the need for targeted public health and clinical interventions to support screening uptake—especially among younger birth cohorts—and to maintain gains achieved after pandemic disruptions. The abstract notes the importance of sustaining momentum but does not provide specific intervention strategies or recommendations in the provided text.
Data for this study were derived from the Vermont Health Care Uniform Reporting and Evaluation System, described as a statewide all-payer insurance claims database covering 2010–2023. The abstract reports key population ages and numerical declines in adherence. The provided source does not include full methodological details, patient-level covariates, granular subgroup analyses, or a comprehensive limitations section in the abstract. Therefore, information on potential confounders, missing data handling, coding definitions for mammography claims, or generalizability beyond Vermont was not reported in the abstract and cannot be inferred beyond what is stated.
Overall, the study uses population-level claims data to document temporal declines in biennial mammography adherence, identifies cohort-specific disparities, and notes a notable postpandemic recovery among younger women. The authors highlight the potential value of sustaining postpandemic screening gains to counteract long-term downward trends in adherence.
