cockcroft: Creatinine clearance by Cockcroft-Gault equation

In transplantr: Audit and Research Functions for Transplantation

Description

A vectorised function to estimate creatinine clearance using the Cockcroft-Gault equation. By default this uses serum creatinine in µmol/l but can be changed to mg/dl by setting the units parameter to "US"

Usage

cockcroft(creat, age, sex, weight, units = "SI")

Arguments

creat	numeric vector of creatinine levels in µmol/l (or mg/dl if units = "US")
age	numeric vector of ages in years
sex	character vector of sex ("F" = female, "M" = male)
weight	numeric vector of weights in kilograms
units	non-vectorised parameter for creatinine units ("SI" for µmol/l (default) or "US" for mg/dl)

Details

Reference: Cockcroft DW, Gault MH. Prediction of creatinine clearance from serum creatinine. Nephron 1976; 16(1):31-41

Value

numeric vector of creatinine clearances in ml/min

Examples

# calculate creatinine clearance using creatinine in µmol/l
cockcroft(creat = 88.4, age = 25, sex = "F", weight = 60)

# calculate using creatinine in mg/dl
cockcroft(creat = 1, age = 25, sex = "F", weight = 60, units = "US")
