raw_epts: Estimated Post-Transplant Survival Score (EPTS)

In transplantr: Audit and Research Functions for Transplantation

Description

A vectorised function to calculate raw EPTS scores for norm-related prediction of patient survival after adult renal transplants. This function generates the raw EPTS scores which can be converted to percentiles using the lookup table on the OPTN website at https://optn.transplant.hrsa.gov/media/2973/epts_mapping_table_2018.pdf

Usage

raw_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 raw EPTS scores

Examples

raw_epts(age = 23.5838467, dm = 0, prev_tx = 1, dx = 5.0814511) # 0.9666517
raw_epts(age = 52.8788501, dm = 0, prev_tx = 0, dx = 0) # 1.440306
raw_epts(age = 22.5242984, dm = 1, prev_tx = 1, dx = 6.8747433) # 1.868751
