Part 3 of the Primary Care Version CME describes the role of the primary care provider in delivering high-quality colonoscopy, such as pre-procedure risk assessment, safety issues to report to the endoscopist, guidance on bowel preparation and sedation, interpreting the endoscopy report, appropriate follow-up for incomplete exams, and questions to ask the endoscopist to be sure he or she is providing high-quality exams. It is the last of three parts of a continuing education activity that provides guidance and tools for clinicians on the optimal ways to implement screening for colorectal cancer to help ensure that patients receive maximum benefit.
