Identifying optimal approaches to scale up colorectal cancer screening: an overview of the centers for disease control and prevention (CDC)'s learning laboratory.

Use of recommended screening tests can reduce new colorectal cancers (CRC) and deaths, but screening uptake is suboptimal in the United States (U.S.). The Centers for Disease Control and Prevention (CDC) funded a second round of the Colorectal Cancer Control Program (CRCCP) in 2015 to increase screening rates among individuals aged 50-75 years. The 30 state, university, and tribal awardees supported by the CRCCP implement a range of multicomponent interventions targeting health systems that have low CRC screening uptake, including low-income and minority populations. CDC invited a select subset of 16 CRCCP awardees to form a learning laboratory with the goal of performing targeted evaluations to identify optimal approaches to scale-up interventions to increase uptake of CRC screening among vulnerable populations. This commentary provides an overview of the CRCCP learning laboratory, presents findings from the implementation of multicomponent interventions at four FQHCs participating in the learning laboratory, and summarizes key lessons learned on intervention implementation approaches. Lessons learned can support future program implementation to ensure scalability and sustainability of the interventions as well as guide future implementation science and evaluation studies conducted by the CRCCP learning laboratory.
