PCORnet® Common Data Model

Created:2025-01

Documentation created by PCORnet® Network Partners for standardizing millions of data points from clinical information systems participating in the PCORnet® Network into a common format.

Phenotype Description

A function to derive the estimated glomerular filtration rate (eGFR) for a cohort of patients with existing serum creatinine and height measurements. eGFR values can be used to evaluate the presence and severity of chronic kidney disease (CKD) and other kidney related conditions.

Downloadable content for this Phenotype includes two R files (cohorts.R and driver.R) and a specs folder, which includes the related concept sets linked below.

Algothrithm Description

These functions will derive the estimated glomerular filtration rate (eGFR) based on age, height, sex, and serum creatinine value of a patient. The resulting number can help to determine the presence and severity of chronic kidney disease or other kidney related conditions.
