Assessing Key Factors for Timely Follow-up after Inconclusive Screening Mammograms within Patients of the Linda Fenner Mobile Mammography Center
Abstract
Introduction and Objective. The Linda Fenner Mobile Mammography Center (LFMMC) was created to reduce disparities in screening for breast cancer and improve survival for women with limited access to such screening. However, for screened patients requiring follow-up testing, research has shown a wide variation of time taken to access diagnostic imaging, especially within uninsured women living in Miami-Dade County (MDC). The objective of this study is to explore factors associated with longer (>30 days) time interval to complete diagnostic imaging after screening. Methods. Retrospective cohort study using data collected through the LFMMC from 2014 to 2022. Women living in Miami-Dade County, over the age of 40, and uninsured who required a follow-up diagnostic imaging after breast cancer screening were included. LFMMC does not screen women with breast pain and/or lumps, a history of breast cancer or previous mammogram in the past year. Factors assessed included women’s age, zip code of residency, race, primary language spoken, marital status, BMI, history of hormone use, previous mammogram, breast implants, breast cancer in immediate family, and past breast surgery, and menopause status. The interval of time taken between receiving a screening mammogram result and completing further diagnostic imaging was the outcome, dichotomized into greater than 30 days (longer follow-up time) or up to 30 days. Multivariable logistic regression models were used to estimate independent associations (odds ratio and 95% confidence interval). Results. We analyzed 926 eligible patients. The mean age was 50.1 years (SD 8.81). About 69% were white, 72% Hispanic, 64% had history of previous mammogram and 82% had no family history of breast cancer. About 53% had a diagnostic follow-up exam performed after 30 days (median time to follow-up was 32, interquartile range 23-46 days). Single women had 30% lower odds of longer follow up compared to married women (OR = 0.70, 95% CI 0.52-0.93). No other statistically significant differences were found. Conclusions-Implications. Being single was associated with shorter time to follow-up with diagnostic imaging. Further research should include a larger sample size, and more details on selected patient factors to identity ways to optimize continuity of care and detect breast cancer at earlier stages.
