epts: Estimated Post-Transplant Survival Score (EPTS)

Description

A vectorised function to calculate EPTS scores as percentiles for norm-related prediction of patient survival after adult renal transplants. This function generates the EPTN scores as percentiles using the most recent lookup table on the OPTN website published in March 2019 and using SRTR data from 2018. The table can be found at https://optn.transplant.hrsa.gov/media/2973/epts_mapping_table_2018.pdf

Usage

epts(age, dm, prev_tx, dx)

Arguments

age

numeric vector of patient age in years (with decimals)

dm

numeric vector of whether patient diabetic (1 = yes, 0 = no)

prev_tx

numeric vector of whether patient has a previous solid organ transplant

dx

numeric vector of duration of dialysis in years (with decimals)

Value

numeric vector of EPTS scores as percentiles

Details

This function requires the dplyr package to be installed. References: https://optn.transplant.hrsa.gov/resources/allocation-calculators/epts-calculator/ and https://optn.transplant.hrsa.gov/media/1511/guide_to_calculating_interpreting_epts.pdf
