a After 2013, the "Renal Function Status" of adult thoracic transplant recipients is no longer available.

The proportion of thoracic (heart, lung, and heart and lung) transplant recipients living with renal dysfunction 1-year post-transplant was more than 15%.
Chart Explanation: The x-axis shows the status of adult (age > 21 years) kidney transplant recipients at 1-year post-transplant. Categories included are dialysis, RD/ESRD, renal transplant, no renal dysfunction, death and renal dysfunction not available.
The y-axis shows the percentage of adult kidney transplant recipients at 1-year post-transplant that fall within each of the categories listed on the x-axis.
Individuals who received a solid organ transplant in the United States were followed up annually for assessment of their health status. These data were recorded in the Scientific Registry of Transplant Recipients (SRTR). All analyses presented are limited to adults aged 20 years or older, at the time of their first organ transplant. These data are nationally-representative of the first-time, solid-organ transplant population with less than 5% lacking information on kidney function.

Diabetes status (type 1 or 2) and hypertension status are as listed at the time of transplant. For all transplant recipients, use of calcineurin inhibitors (CNI) to prevent transplant rejection is presented as many of these medications have been shown to be nephrotoxic1. The recording of data in the SRTR pertaining to CKD/kidney function varied by organ type and is discussed below.

Thoracic transplant (heart, lung, and combined heart and lung) recipients did not have a serum creatinine measurement reported but rather a yes/no “renal dysfunction” indicator at follow-up. Information on treatment for ESRD (through dialysis or kidney transplant) is provided for thoracic transplant recipients (all patients treated for ESRD are necessarily indicated to have “renal dysfunction,” but an individual with “renal dysfunction” may or may not have been treated for ESRD). A thoracic transplant patient was defined as having “renal dysfunction” if the patient was reported as such. We have therefore retained the terminology “renal dysfunction” as opposed to “CKD” for this section of the website.

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.
