尽管准确性存在问题，但自动化数据越来越多地用于研究和质量测量。本研究的目的是开发一种自动数据算法，旨在区分筛查和诊断性内窥镜检查（乙状结肠镜检查和结肠镜检查）。我们评估了该算法使用纸质病历作为“金标准”正确分类考试的能力。该算法使用诊断代码来识别内窥镜检查的适应症。该算法对诊断性乙状结肠镜检查和结肠镜检查的敏感性分别为48.1%和23.8%。该算法错过了大多数诊断性内窥镜检查。相反，乙状结肠镜检查和结肠镜检查的敏感性较高（分别为87.9%和84.4%），但特异性较低。我们的研究结果表明，如果不考虑适应症，仅依赖自动数据的研究会高估筛查率。这里提出的自动算法需要进一步改进，以更好地区分筛查和诊断检查。
Despite questions about accuracy, automated data are used increasingly for research and quality measurement. The goal of this study was to develop an automated data algorithm designed to distinguish screening and diagnostic endoscopy (sigmoidoscopy and colonoscopy) exams. We assessed the algorithm's ability to correctly classify the exams using paper medical records as the “gold standard.” The algorithm used diagnostic codes to identify the indication of the endoscopies. The algorithm's ability to classify the indication varied by endoscopy exam. The sensitivities for identifying diagnostic sigmoidoscopy and colonoscopy were 48.1% and 23.8%, respectively. The algorithm missed most of the diagnostic endoscopies. Conversely, the sensitivities for identifying screening sigmoidoscopy and colonoscopy were high (87.9% and 84.4%, respectively) but were associated with low specificities. Our findings suggest that studies relying solely on automated data overestimate screening rates if indication is not considered. The automated algorithm presented here needs further improvements to better differentiate screening from diagnostic exams.
