Insurance coverage mandates: Impact of physician utilization in moderating colorectal cancer screening rates

Precision public health requires research that supports innovative systems and health delivery approaches, programs, and policies that are part of this vision. This study estimated the effects of health insurance mandate (HiM) variations and the effects of physician utilization on moderating colorectal cancer (CRC) screening rates. A time-series analysis using a difference-in-difference-in-differences (DDD) approach was conducted on CRC screenings (1997–2014) using a multivariate logistic framework. Key variables of interest were HiM, CRC screening status, and physician utilization. The adjusted average marginal effects from the DDD model indicate that physician utilization increased the probability of being “up-to-date” vs. non-compliance by 9.9% points (p = 0.007), suggesting that an estimated 8.85 million additional age-eligible persons would receive a CRC screening with HiM and routine physician visits. Routine physician visits and mandates that lower out-of-pocket expenses constitute an effective approach to increasing CRC screenings for persons ready to take advantage of such policies. •Routine physician visits and health insurance mandates that reduce out-of-pocket expenses represent an effective approach to increase colorectal cancer screenings.•Such policies have historically been used to improve health outcomes, and as public health strategies, they are currently being used to increase preventive health services and, in turn, to improve the nation's health.•Future research examining mandates that lower out-of-pocket costs should continue post-election to inform policymakers.
