Abstract

Introduction: Administrative health data could contribute to generalizable microscopic colitis insights, but International Classification of Diseases (ICD) codes for microscopic colitis have not been validated.

Methods: We identified individuals who received care for diarrhea in the Veterans Health Administration and classified them by receipt of microscopic colitis ICD codes. We reviewed random samples of charts to calculate the positive predictive value (PPV) and negative predictive value (NPV). We then calculated the sensitivity and specificity in clinically relevant cohorts.

Results: The PPV was 0.790 and the NPV was 0.995. In a cohort of individuals with diarrhea who underwent colonoscopy, the sensitivity and specificity were 0.734 and 0.996, respectively.

Conclusion: Alternative ascertainment methods for microscopic colitis are needed because ICD codes have suboptimal performance.

微小结肠炎诊断代码的次优表现：流行病学洞察力的瓶颈。

导言：行政健康数据有助于深入了解微小结肠炎，但微小结肠炎的国际疾病分类（ICD）代码尚未得到验证：我们确定了在退伍军人健康管理局接受过腹泻治疗的人员，并根据微小结肠炎的 ICD 编码对他们进行了分类。我们对病历进行了随机抽样，以计算阳性预测值 (PPV) 和阴性预测值 (NPV)。然后，我们计算了临床相关组群的灵敏度和特异性：结果：PPV 为 0.790，NPV 为 0.995。在接受结肠镜检查的腹泻患者队列中，灵敏度和特异性分别为 0.734 和 0.996：结论：由于 ICD 代码的性能不够理想，因此需要采用其他方法来确定微小结肠炎。

期刊介绍： Clinical and Translational Gastroenterology (CTG), published on behalf of the American College of Gastroenterology (ACG), is a peer-reviewed open access online journal dedicated to innovative clinical work in the field of gastroenterology and hepatology. CTG hopes to fulfill an unmet need for clinicians and scientists by welcoming novel cohort studies, early-phase clinical trials, qualitative and quantitative epidemiologic research, hypothesis-generating research, studies of novel mechanisms and methodologies including public health interventions, and integration of approaches across organs and disciplines. CTG also welcomes hypothesis-generating small studies, methods papers, and translational research with clear applications to human physiology or disease.
