Screening, followed by colonoscopic polypectomy (or surgery for malignant lesions), prevents incident colorectal cancer and mortality. However, there are variations in effective application of nearly every aspect of the screening process. Screening is a multistep process, and failure in any single step could result in unnecessary morbidity and mortality. Awareness of variations in operator- and system-dependent performance has led to detailed, comprehensive recommendations in the United States and Europe on how colonoscopy screening should be performed and measured. Likewise, guidance has been provided on quality assurance for nonprimary colonoscopy-based screening programs, including strategies to maximize adherence. Quality improvement is now a validated science, and there is clear evidence that higher quality prevents incident cancer and cancer death. Quality must be addressed at the levels of the system, provider, and individuals, to maximize the benefits of screening for any population. We review the important aspects of measuring and improving the quality of colorectal cancer screening.

在全球范围内优化结肠直肠癌筛查的质量。

进行筛查，然后进行结肠镜息肉切除术（或恶性病变的手术），可预防大肠癌的发生和死亡率。但是，在筛选过程的几乎每个方面的有效应用方面都存在差异。筛查是一个多步骤的过程，任何一个步骤的失败都可能导致不必要的发病率和死亡率。意识到操作员和系统相关性能的差异，已导致在美国和欧洲提出详细，全面的建议，说明应如何进行结肠镜检查和测量。同样，已经为基于非主要结肠镜检查的筛查程序提供了质量保证方面的指导，包括最大限度地提高依从性的策略。质量改进现在是一门经过验证的科学，并且有明确的证据表明，更高的质量可以防止意外癌症和癌症死亡。必须在系统，提供者和个人的层次上解决质量问题，以最大化针对任何人群进行筛查的好处。我们回顾了衡量和提高结肠直肠癌筛查质量的重要方面。
