- W4205671476 abstract "Abstract Purpose: Black women newly diagnosed with breast cancer and who have multiple comorbidities at the time of cancer diagnosis require greater care coordination to simultaneously manage cancer care and other chronic conditions. Care coordination may be complicated when multiple clinicians from diverse disciplines are involved in managing care and are located in different health systems, defined as care fragmentation. Given that Black women are disproportionately burdened by comorbidities and breast cancer, we examined the degree of care fragmentation and care coordination experienced by this group from a health system and care team perspective using two population-based cohorts. Methods: We analyzed data from two separate cohorts of Black women diagnosed with breast cancer who had diabetes and/or cardiovascular disease. In the first study we used the Women's Circle of Health Follow-Up Study (n=228) to examine types of practice setting for first primary care visit and primary breast surgery, and, through medical chart abstraction, identified whether care visit was within or outside the same health system. In a separate study, we identified women from the SEER-Medicare database (n=3,420) diagnosed with breast cancer and used encounter claims to examine the complexity and composition of the clinical care team. Results: Care fragmentation was experienced by 79% of Black women in the Women's Circle of Health Follow-Up Study, and individual-level factors (age, health insurance, cancer stage, and comorbidity count) were not associated with care fragmentation (p>.05). In the SEER-Medicare cohort, the most common clinical care team composition was oncology with primary care (45%) followed by oncology, primary care, and medical subspecialty (26%). In the adjusted model, Black women were more likely to have a clinical care team of higher complexity if they had cardiopulmonary disease (OR: 1.74; 95% CI: 1.68, 1.81) or diabetes (OR: 1.69; 95% CI: 1.63,1.75) compared with hypertension only. Women were also less likely to have a complex care team if they were dual Medicaid-Medicare covered (OR: 0.56; 95% CI: 0.48, 0.65) compared with Medicare only, rural residents (OR: 0.54; 95% CI: 0.42, 0.65) compared with urban, or diagnosed with stage III cancer (OR: 0.59; 95% CI: 0.47, 0.75) compared with stage I. Conclusion: The majority of Black breast cancer survivors with comorbidities see multiple clinicians from diverse disciplines and in different health systems, illustrating high care coordination demands and care fragmentation. However, the impact of the health system and care team on care outcomes still need to be assessed, and this includes care transitions into survivorship. To address cancer care disparities experienced by Black women, future research should consider examining clinician's perspectives regarding roles and responsibilities for chronic disease management and cancer care, as well as address care fragmentation across diverse healthcare delivery settings.
