Reappraising risk factors for inflammatory bowel disease-associated neoplasia: implications for colonoscopic surveillance in IBD.
One of the most feared complications of inflammatory bowel disease [IBD]-associated colitis is colorectal cancer. An opportunity for early detection is being missed in a group that is overlooked as high-risk, as a substantial proportion of colorectal cancers are being diagnosed in individuals with colonic IBD who have disease duration shorter than when guidelines recommend surveillance initiation. In this study, the investigators discuss a viewpoint that supports a paradigm shift that will ideally result in a more effective and higher-value colorectal cancer prevention approach in IBD.

Antiplatelets, anticoagulants, and colonoscopic polypectomy.
This article is a review of current best practice recommendations focusing on the risk of immediate and delayed postpolypectomy bleeding in the context of drug discontinuation or continuation of antiplatelet and anticoagulant drugs. Data was assessed whether cold snare vs conventional thermal-based polypectomy technology and prophylactic placement of hemostatic clips are endoscopic techniques that are beneficial in reducing polypectomy bleeding. Clinical takeaways are also provided to facilitate safer polypectomy among patients on antiplatelet and anticoagulant agents.

Key collaborative factors when Medicaid Accountable Care Organizations work with primary care clinics to improve colorectal cancer screening: relationships, data, and quality improvement infrastructure.
This study focused on ways that Medicaid Accountable Care Organizations (ACOs) are implementing interventions with primary care clinics to improve colorectal cancer screening. The researchers conducted a comparative case study of 14 Medicaid ACOs in Oregon and their contracted primary care clinics. They focused on interventions that reduced structural barriers (12 ACOs), delivered provider assessment and feedback (11 ACOs), and provided patient reminders (7 ACOs). There was an unintended consequence of potential exclusion of smaller clinics and metric focus and fatigue.

Changes in screening colonoscopy following Medicare reimbursement and cost-sharing changes.
This study examined changes in screening colonoscopy rates after Medicare reimbursement and cost-sharing changed when the Affordable Care Act (ACA) was implemented. A 20% random sample of fee-for-service (FFS) Medicare claims from 2002-2012 was used in this study. Screening colonoscopy rates did increase after 2001 when cost-sharing was eliminated but the amount varied depending on the algorithm used to classify the indication.

Reference pricing: the case of screening colonoscopies.
In this study, the investigators studied the introduction of reference pricing to the California Public Employees' Retirement System. The investigators found a 10 percentage point increase in the share of patients using an ambulatory surgery center (ASC), leading to a $2300 to $1700 reduction in prices paid for patients who switched to ASCs. They indicated that their results suggested the use of ASCs had a causal effect on prices paid and had no negative effect on patient health outcomes.

What happened to disparities in CRC screening among FFS Medicare enrollees following Medicare modernization?
This study examined the effects of the change in policy for colorectal screening that was implemented in 2006 for FFS Medicare beneficiaries. This new policy eliminated copayments for colonoscopies or sigmoidoscopies. Disparities in screening by race (Blacks, Asians and Hispanics relative to Whites), and gender (Males relative to Females). The time periods 2001-2005 and 2006-2009 were compared and while there was some improvement in screening rates for minorities and women, the progress was unevenly distributed across the USA.
