After cancer diagnosis, non-White patients and those with multimorbidity use less primary care and more acute care than non-Hispanic White (NHW) patients and those lacking comorbidities. Yet, positive patient experiences with physician communication (PC) are associated with more appropriate health care use. In a multimorbid cohort, we measured associations between PC experience, race and ethnicity, and health care use following colorectal cancer (CRC) diagnosis. We identified 2606 participants using Surveillance, Epidemiology, and End Results (SEER)-Consumer Assessment of Health Care Providers and Systems (CAHPS) data who were diagnosed with CRC from 2001 to 2017 with pre-existing chronic conditions. Self-reported PC experiences were derived from Medicare CAHPS surveys. Chronic condition care, emergency department, and hospital use following CRC diagnosis were identified from Medicare claims. Simple survey-weighted multivariable logistic regression stratified by experiences with care analyzed associations between race and ethnicity and health care use. Among patients reporting excellent PC experience, non-Hispanic Black (NHB), Hispanic, and non-Hispanic Asian (NHA) patients were more likely to use sufficient chronic condition care than NHW patients (NHB: OR=1.48, 99.38% CI=1.38-1.58; Hispanic: OR=1.34, 99.38% CI=1.26-1.42; NHA: OR=2.31, 99.38% CI=2.12-2.51). NHB and NHA patients were less likely than NHW patients to visit the emergency department when reporting excellent PC experience (NHB: OR=0.66, 99.38% CI=0.63-0.69; NHA: OR=0.67, 99.38% CI=0.64-0.71). Among patients reporting excellent PC, NHB, Hispanic, and NHA patients were less likely than NHW patients to be hospitalized (NHB: OR=0.93, 99.38% CI=0.87-0.99; Hispanic: OR=0.93, 99.38% CI=0.87-0.99; NHA: OR=0.20, 99.38% CI=0.19-0.22). Improving patient experiences with PC, particularly among older racial and ethnic minority cancer survivors with chronic conditions, may help reduce disparities in adverse healthcare use following CRC diagnosis.
