For patients with chronic kidney disease (i.e., those with estimated glomerular filtration rate (eGFR) less than 60 mL/min/1.73m^{2}), this calculator returns an estimated probability of developing kidney failure in the next two or five years (expressed as a percentage, or a range of percentages, from 0% to 100%).
These probabilities could be used to facilitate patient and provider communication, to heighten awareness and guide optimal disease management for best outcomes.
Two versions of this calculator are provided, one with four input variables, and one with eight input variables.
Using more variables, when available, will yield a more precise estimate.
The ‘sliders’ for each laboratory variable in the data entry table below allow a range of values to be selected in case of uncertainty in a single value.
Details of risk equation development (Tangri et al., 2011) are available here: https://www.ncbi.nlm.nih.gov/pubmed/21482743.
