Higher stages of CKD at 1-year post-transplant were associated with more severe progression by the third year.
Chart Explanation: The results presented show the progression of CKD in solid organ recipients from their first year of follow-up to their third year, including progression to ESRD or death. 
Individuals who receive a solid organ transplant in the United States are followed up annually for assessment of their health status. These data are recorded in the Scientific Registry of Transplant Recipients (SRTR). All analyses presented are limited to adults, 20 years of age and older, at the time of their first organ transplant. These data are nationally-representative of the first-time, solid-organ transplant population with fewer than 5% lacking information on kidney function.

These data are recorded in the Scientific Registry of Transplant Recipients (SRTR). All analyses presented are limited to adults, 20 years of age and older, at the time of their first organ transplant. These data are nationally-representative of the first-time, solid-organ transplant population with fewer than 5% lacking information on kidney function.

Patients were classified into those that showed worsening eGFR over three years (i.e., moving to a more severe stage of CKD), stable (i.e., remaining in the same CKD stage) and those that showed apparent “improvement” (i.e. moved to a less severe CKD stage). These categories were then examined by age categories, gender, race/ethnicity, diabetes, and hypertension for a preliminary examination of potential predictors of change in CKD stage over the three years.

Pending DataNone.
Additional Data Items of InterestTrends over time, other stratification variables of interest.
Limitations of IndicatorReporting of data across organ types is not consistent. Reporting of kidney function for thoracic recipients may be subjective. Serum creatinine measurements are only taken once per follow-up, probably resulting in a large standard error.
Analytical ConsiderationsMissing data on serum creatinine measurements may be informative.
