transplantr (version 0.2.0)

soft2_US: SOFT score from P-SOFT (US units)

Description

A wrapper using US units for the soft2() vectorised function to calculate SOFT Scores for predicting patient survival after liver transplantation when the P-SOFT score is already known. The P-SOFT Score can be calculated using the transplantr::p_soft() function. Alternatively, the SOFT Score can be calculated in full, including the P-SOFT parameters using the transplantr::soft() or transplantr::soft_US() function. The units for donor serum creatinine are in mg/dl

Usage

soft2_US(PSoft, PortalBleed, DonorAge, DonorCVA, DonorSCr, National, CIT)

Arguments

PSoft

numeric vector of P-SOFT scores

PortalBleed

numeric vector of whether portal bleeding in 48 hours pre-transplant (1 = "yes", 0 = "no")

DonorAge

numeric vector of donor ages in years

DonorCVA

numeric vector of whether donor cause of death is CVA/stroke (1 = "yes", 0 = "no")

DonorSCr

numeric vector of donor terminal serum creatinine in mg/dl

National

numeric vector of whether national allocation (1 = "yes", 0 = "no")

CIT

numeric vector of cold ischaemic time in hours

Value

numeric vector of SOFT Scores
