Association of Medicaid enrollee characteristics and primary care utilization with cancer outcomes for the period spanning Medicaid expansion in New Jersey.

Medicaid patients with cancer diagnosed just before and in the initial year of eligibility expansion had worse outcomes than non-Medicaid cases. Poor outcomes were especially pronounced among new enrollees, those without outpatient visits before their diagnosis, and FFS enrollees. Targeted strategies to enhance care continuity, including access to PC providers before the diagnosis and a better understanding of pathways to cancer care upon Medicaid enrollment, are needed to improve outcomes in this population.
