There are different methods to identify chronic kidney disease (CKD) in Clinical Practice Research Datalink (CPRD)-Hospital Episode Statistics (HES). Using CPRD-HES, nonvalvular atrial fibrillation patients were classified according to CKD category. Using glomerular filtration rate/estimated glomerular filtration rate tests only to identify patients with CKD resulted in 3.5% stage 2, 2.7% stage 3, 0.3% stage 4 and 0.03% stage 5. Using data from diagnostic codes to identify patients with CKD resulted in 1.4% stage 3, 0.4% stage 4 and 0.3% stage 5. Using test records and codes resulted in 3.5% stage 2, 4.0% stage 3, 0.6% stage 4 and 0.4% stage 5. To identify CKD status in CPRD-HES, a combination of test records and codes should be used. Using diagnostic codes only significantly underestimates CKD prevalence.
在临床实践研究数据库(CPRD)-医院入院统计(HES)中有不同的方法可以识别慢性肾脏病(CKD)。 使用 CPRD-HES,根据 CKD 类别对非瓣膜性心房颤动患者进行分类。 使用肾小球滤过率/估计肾小球滤过率检查仅识别 CKD 患者会导致 2 期 3.5%、3 期 2.7%、4 期 0.3%和 5 期 0.03%。 使用诊断代码数据识别 CKD 患者会导致 3 期 1.4%、4 期 0.4%和 5 期 0.3%。 使用检查记录和代码会导致 2 期 3.5%、3 期 4.0%、4 期 0.6%和 5 期 0.4%。 要在 CPRD-HES 中识别 CKD 状态,应结合使用检查记录和代码。 仅使用诊断代码会严重低估 CKD 的患病率。
