关于常规实践中结肠镜检查导致息肉检测的比例的国家级数据有限。我们的目标是确定人群亚组中结肠镜检查的诊断率。我们回顾了1999年接受结肠镜检查的所有65岁或65岁以上的按服务收费受益人的医疗保险索赔数据。使用诊断和手术代码，估计息肉手术的比例。使用三种不同的息肉检测标准。确定了大约180万次结肠镜检查程序。根据使用的具体标准，23.9%至35.7%的检查发现息肉。年轻患者、男性和白人的检出率最高。结肠镜检查在息肉检测方面的表观产率至少为24%。这些数据可能在预测与结肠镜检查相关的治疗程序的资源分配方面提供信息。未来的研究应确定使用和收益的一系列结肠镜检查息肉监测。
National-level data on the proportion of colonoscopies in routine practice that result in polyp detection are limited. Our goal was to determine the diagnostic yield of colonoscopy among population subgroups. We reviewed Medicare claims data for all fee-for-service beneficiaries 65 years or older who underwent colonoscopy in 1999. With the use of diagnosis and procedure codes, the proportion of procedures with polyps was estimated. Three different criteria for polyp detection were used. Approximately 1.8 million colonoscopy procedures were identified. Depending on the specific criteria used, 23.9% to 35.7% of examinations noted polyps. The detection rate was highest in younger patients, men, and whites. The apparent yield of colonoscopy in terms of polyp detection is at least 24%. These data may be informative in predicting resource allocation for therapeutic procedures associated with colonoscopy. Future studies should determine the use and yield of serial colonoscopies for polyp surveillance.
