The Development and Use of an EHR-Linked Database for Glomerular Disease Research and Quality Initiatives.

ÌÇÐÄ´«Ã½

Abstract

The use of electronic health record (EHR) data can facilitate efficient ÌÇÐÄ´«Ã½ and quality initiatives. The imprecision of ICD-10 codes for kidney diagnoses has been an obstacle to discrete data-defined diagnoses in the EHR. This manuscript describes the Kidney Research Network (KRN) registry and database that provide an example of a prospective, real-world data glomerular disease registry for ÌÇÐÄ´«Ã½ and quality initiatives.KRN is a multicenter collaboration of patients, physicians, and scientists across diverse health-care settings with a focus on improving treatment options and outcomes for patients with glomerular disease. The registry and data warehouse amasses retrospective and prospective data including EHR, active ÌÇÐÄ´«Ã½ study, completed clinical trials, patient reported outcomes, and other relevant data. Following consent, participating sites enter the patient into KRN and provide a physician-confirmed primary kidney diagnosis. Kidney biopsy reports are redacted and uploaded. Site programmers extract local EHR data including demographics, insurance type, zip code, diagnoses, encounters, laboratories, procedures, medications, dialysis/transplant status, vitals, and vital status monthly. Participating sites transform data to conform to a common data model prior to submitting to the Data Analysis and Coordinating Center (DACC). The DACC stores and reviews each site's EHR data for quality before loading into the KRN database.As of January 2021, 1,192 patients have enrolled in the registry. The database has been utilized for ÌÇÐÄ´«Ã½, clinical trial design, clinical trial end point validation, and supported quality initiatives. The data also support a dashboard allowing enrolling sites to assist with clinical trial enrollment and population health initiatives.A multicenter registry using EHR data, following physician- and biopsy-confirmed glomerular disease diagnosis, can be established and used effectively for ÌÇÐÄ´«Ã½ and quality initiatives. This design provides an example which may be readily replicated for other rare or common disease endeavors.
