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.

Cross-cultural survey development: the colon cancer screening behaviors survey for South Asian populations.
The objective of this work was to develop a survey that considered cultural relevance and diversity of South Asian populations, with the aim of describing or predicting factors that influence colorectal cancer screening intention and adherence. The initial development of the Colon Cancer Screening Behaviours Survey for South Asian populations was completed using a number of steps. This initial survey was later cross-culturally translated and adapted into the Urdu language.

Effect of colonoscopy outreach vs fecal immunochemical test outreach on colorectal cancer screening completion: a randomized clinical trial.
Researchers compared the effectiveness of fecal immunochemical test (FIT) outreach and colonoscopy outreach to increase completion of the colorectal cancer (CRC) screening process (screening initiation and follow-up) within 3 years. Among persons aged 50 to 64 years receiving primary care at a safety-net institution, mailed outreach invitations offering FIT or colonoscopy compared with usual care increased the proportion completing CRC screening process within 3 years.

Geographic and population-level disparities in colorectal cancer testing: a multilevel analysis of Medicaid and commercial claims data.
This study used Medicaid and commercial claims data to examine individual and geographic factors associated with colorectal cancer testing rates in Oregon. CRC testing in newly age-eligible Medicaid and commercial members remains markedly low. Disparities exist by gender, geographic residence, insurance coverage, and access to primary care.

The value of explicitly emulating a target trial when using real world evidence: an application to colorectal cancer screening.
Researchers reviewed a recent observational analysis that explicitly emulated a target trial of screening colonoscopy using insurance claims from U.S. Medicare. They then compared this explicit emulation with alternative, simpler observational analyses. This empirical comparison suggests that lack of an explicit emulation of the target trial leads to biased estimates, and shows that allowing for repeated eligibility increases the statistical efficiency of the estimates.

Screening for colorectal cancer.
This case study involves a 50-year-old woman who presents for a routine visit. She is healthy with no significant medical history, takes no medications, and has no personal or family history of cancer. She asks about colorectal cancer screening. There are three multiple choice questions together with the U.S. Preventive Services Task Force answers, recommendations and related background information.

Inadequate utilization of diagnostic colonoscopy following abnormal FIT results in an integrated safety-net system.
The effectiveness of stool-based colorectal cancer (CRC) screening is contingent on colonoscopy completion in patients with an abnormal fecal immunochemical test (FIT). This study found that FIT positive patients never referred to gastroenterology or who missed their appointment after referrals were more likely to have comorbid conditions and documented illicit substance use compared with patients who completed a colonoscopy.

Effectiveness of screening colonoscopy to prevent colorectal cancer among Medicare beneficiaries aged 70 to 79 years: a prospective observational study.
The researchers evaluated the effectiveness and safety of screening colonoscopy to prevent colorectal cancer (CRC) in persons aged 70 to 74 and those aged 75 to 79 years. They concluded that screening colonoscopy may have had a modest benefit in preventing CRC in beneficiaries aged 70 to 74 years and a smaller benefit in older beneficiaries.

Reasons for lack of diagnostic colonoscopy after positive result on fecal immunochemical test in a safety-net health system.
This study aimed to characterize factors contributing to lack of follow-up colonoscopy in a racially diverse and socioeconomically disadvantaged cohort of patients with abnormal results on the fecal immunochemical test receiving care in an integrated safety-net health system. It concluded that lack of diagnostic evaluation is related to a combination of patient-, provider-, and system-level factors, highlighting the need for multilevel interventions to improve follow-up colonoscopy completion rates.
