phoenix_hepatic: Phoenix Hepatic Score

Description

Apply the Phoenix Hepatic scoring based on total bilirubin and ALT.

Usage

phoenix_hepatic(
  bilirubin = NA_real_,
  alt = NA_real_,
  data = parent.frame(),
  ...
)

Value

a integer vector with values 0 or 1

As with all other Phoenix organ system scores, missing values in the data set will map to a score of zero - this is consistent with the development of the criteria.

Arguments

bilirubin

numeric vector; units of mg/dL

alt

alanine aminotransferase; a numeric vector; units of IU/L

data

a list, data.frame, or environment containing the input vectors

...

pass through

Phoenix Hepatic Scoring

1 point for total bilirubin greater or equal to 4 mg/dL and/or ALT strictly greater than 102 IU/L.
