Impact of Unmet Social Needs on Access to Breast Cancer Screening and Treatment: An Analysis of Barriers Faced by Patients in a Breast Cancer Navigation Program

Résumé fourni par la source

BACKGROUND: Unmet structural and social needs create barriers to breast cancer screening and treatment. The impact of the intersection of these barriers on screening participation and timeliness of breast cancer care remains poorly understood. METHODS: People identifying as women participating in a breast cancer navigation program for screening or treatment were included. Patient navigators administered survey questions that addressed potential barriers to care access using the Health Leads Screening Toolkit. Odds ratios were calculated for unadjusted bivariate associations, and Cox proportional hazards were used to examine the relationship between barriers and time to treatment. RESULTS: A total of 2804 women (mean age, 53 years) enrolled in navigation for screening or cancer treatment participated in the survey about barriers to care. Of those, 435 (16%) reported unstable housing, 610 (23%) reported poor health literacy, and 164 (6%) reported feeling depressed. Limited transportation was significantly associated with unstable housing (odds ratio [OR] = 26.5, 95% confidence interval [CI] 19.9-35.4, p < 0.00001), poor health literacy (OR = 11.5, 95% CI 9.3-14.2, p < 0.0001), and depression (OR = 2.9, 95% CI 2.1-4.0, p < 0.00001). Individual barriers were not associated with a longer time to treatment, but an increasing number of barriers was associated with a longer time to treatment (Coef = 0.9, p < 0.05). CONCLUSIONS: Compounding structural and social barriers limit participation in breast cancer screening, and women with increasing unmet social needs face delays in treatment for breast cancer. Navigation programs may help women overcome barriers to care; however, understanding and targeting the intersectionality of unmet needs is essential for targeted interventions through breast cancer care navigation programs to be effective.
