Chopra I, et al. - In this retrospective longitudinal study, researchers used the SEER-Medicare linked registries to assess the link between incident cancer and coronary artery disease (CAD)-related expenditures among elderly fee-for-service Medicare beneficiaries with preexisting CAD and with incident breast, colorectal, or prostate cancer (N=12,095) or no cancer (N=34,237). Medicare payments for inpatient, home healthcare, and outpatient services were analyzed to determine CAD-related healthcare expenditures. Every 120 days during the 1-year preindex and 1-year postindex periods, they assessed the expenditures. They used the generalized linear mixed models to determine the adjusted link between incident cancer and expenditures. For elderly Medicare beneficiaries with incident cancer, specifically for those with colorectal cancer (CRC), higher CAD-related expenditures were reported. CAD-related events and expenditures could be prevented by close monitoring of patients with a cancer diagnosis and preexisting CAD.
