ABSTRACT
In 2015, the Centers for Medicare and Medicaid Services started reimbursing chronic care management (CCM) services for patients with multiple chronic conditions. This study used 2015-2020 Medicare claims data from Illinois, Iowa, Minnesota, and Wisconsin and conducted a retrospective cohort study of 885,132 beneficiaries with an evaluation and management visit, following a diabetes diagnosis with other co-occurring chronic conditions. A competing-risk model was estimated to analyze factors associated with patients’ receipt of their first CCM services and a Cox proportional hazard model was estimated to assess the risk of death post-CCM initiation. Diabetic patients with multiple chronic conditions had mean age of 70 years (SD = 10.3), 50.7% were female, and 81.3% were white. 1.0% (9,075 beneficiaries) had CCM claims. Excluding chronic conditions, variables associated with a higher likelihood of CCM initiation included age (sub-distribution hazard ratios [SHR] = 1.003 for each additional year, 95% CI:1.00-1.01), female (SHR = 1.10, 95%CI:1.05-1.15), Black (SHR = 1.27, 95% CI:1.19-1.36) or Hispanic (SHR = 1.40, 95% CI:1.23-1.58), receiving care at home (SHR = 5.00, 95% CI:4.55-5.51) or skilled nursing facilities (SHR = 1.60, 95% CI:1.48-1.73), being a non-Iowa resident, and getting a diabetes diagnosis post-2015. However, patients in non-urban areas were less likely to receive such services. No statistical difference was found in the likelihood of mortality with CCM initiation vs. non-CCM. After accounting for CCM initiation, variables associated with a higher likelihood of death included age, American Indian/Alaska Native, residing in non-urban areas, getting a diabetes diagnosis in 2020, and receiving care in non-outpatient settings. CCM remains largely underutilized among Medicare beneficiaries. Addressing barriers, including improving access in non-urban areas and managing chronic condition earlier, may enhance adoption and decrease the risk of death for patients with multimorbidity.
