Changes in renal function over time in outpatients with eGFR ≥ 30 mL/min/1.73 m²: implication for timing of renal function testing before contrast-enhanced CT imaging.

ABSTRACT:

Purpose

To evaluate the associations between comorbidities and kidney function decline at 6-month and 1-year follow-up in outpatients with initial estimated glomerular filtration rate (eGFR) ≥ 30 mL/min/1.73 m².

Materials and methods

Outpatients aged 18 and older with confirmed diagnosis, who had eGFR ≥ 30 mL/min/1.73 m² measured between April 2017 and March 2019, were included in this retrospective observational study. Of them, 30,595 included outpatients had 6-month eGFR test and 27,698 included outpatients had 1-year eGFR test. The outpatients were further divided into two groups based on initial eGFR: between 30 and 59 and ≥ 60 mL/min/1.73 m². Impaired renal function was defined as eGFR declined to below 30 mL/min/1.73 m².
