摘要:

慢性肾脏疾病(CKD)是一种缓慢进展的疾病,最终可能需要肾脏替代治疗(RRT),包括透析或肾移植。早期识别需要RRT的患者(最多提前1年)可改善患者结局,例如通过允许更高质量的血管通路进行透析。因此,护理团队及早认识到RRT的必要性是成功管理疾病的关键。遗憾的是,目前尚无常用的RRT启动预测工具。在这项工作中,我们提出了一个机器学习模型,动态识别CKD患者的风险,需要RRT提前一年只使用索赔数据。为了评估该模型,我们研究了大约300万名医疗保险受益人,并对其进行了800多万次预测。我们表明,该模型可以识别风险患者,灵敏度和特异性超过90%。虽然在这种方法准备用于临床之前还需要做更多的工作,但这项研究为筛选工具提供了基础,可以在一个时间窗内识别有风险的患者,从而实现旨在改善RRT结局的早期积极干预。

英文摘要:

Chronic kidney disease (CKD) represents a slowly progressive disorder that can eventually require renal replacement therapy (RRT) including dialysis or renal transplantation. Early identification of patients who will require RRT (as much as 1 year in advance) improves patient outcomes, for example by allowing higher-quality vascular access for dialysis. Therefore, early recognition of the need for RRT by care teams is key to successfully managing the disease. Unfortunately, there is currently no commonly used predictive tool for RRT initiation. In this work, we present a machine learning model that dynamically identifies CKD patients at risk of requiring RRT up to one year in advance using only claims data. To evaluate the model, we studied approximately 3 million Medicare beneficiaries for which we made over 8 million predictions. We showed that the model can identify at risk patients with over 90% sensitivity and specificity. Although additional work is required before this approach is ready for clinical use, this study provides a basis for a screening tool to identify patients at risk within a time window that enables early proactive interventions intended to improve RRT outcomes.
