Development and Validation of a Pragmatic Electronic Phenotype for CKD.

Background And Objectives: Poor identification of individuals with CKD is a major barrier to research and appropriate clinical management of the disease. We aimed to develop and validate a pragmatic electronic (e-) phenotype to identify patients likely to have CKD.

Design, Setting, Participants, & Measurements: The e-phenotype was developed by an expert working group and implemented among adults receiving in- or outpatient care at five healthcare organizations.
