soft_US: SOFT score (Survival Outcomes Following Liver...

In transplantr: Audit and Research Functions for Transplantation

Description

A wrapper function using US units for the soft() vectorised function to calculate SOFT Scores for predicting patient survival after liver transplantation. The units for donor serum creatinine and recipient serum albumin in g/l.

Usage

soft_US(Age, BMI, PrevTx, AbdoSurg, Albumin, Dx, ICU, Admitted, MELD,
  LifeSupport, Encephalopathy, PVThrombosis, Ascites, PortalBleed,
  DonorAge, DonorCVA, DonorSCr, National, CIT)

Arguments

Age	numeric vector of patient ages in years
BMI	numeric vector of patient BMI in kg/m2
PrevTx	numeric vector of number of previous transplants
AbdoSurg	numeric vector of whether previous abdominal surgery (1 = "yes", 0 = "no")
Albumin	numeric vector of serum albumin in g/dl
Dx	numeric vector of whether on dialysis before transplant (1 = "yes", 0 = "no")
ICU	numeric vector of whether patients in intensive care unit before transplant (1 = "yes", 0 = "no")
Admitted	numeric vector of whether admitted to hospital pre-transplant (1 = "yes", 0 = "no")
MELD	numeric vector of MELD scores
LifeSupport	numeric vector of whether on life support pre-transplant (1 = "yes", 0 = "no")
Encephalopathy	numeric vector of whether encephalopathy present (1 = "yes", 0 = "no")
PVThrombosis	numeric vector of whether portal vein thrombosis (1 = "yes", 0 = "no")
Ascites	numeric vector of whether ascites pre-transplant (1 = "yes", 0 = "no")
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
