phoenix_coagulation: Phoenix Coagulation Score

Description

Applies the Phoenix coagulation organ dysfunction scoring to a set of inputs.

Usage

phoenix_coagulation(
  platelets = NA_real_,
  inr = NA_real_,
  d_dimer = NA_real_,
  fibrinogen = NA_real_,
  data = parent.frame(),
  ...
)

Value

a integer vector with values 0, 1, or 2

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

platelets

numeric vector for platelets counts in units of 1,000/uL (thousand per microliter)

inr

numeric vector for the international normalised ratio blood test

d_dimer

numeric vector for D-Dimer, units of mg/L FEU

fibrinogen

numeric vector units of mg/dL

data

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

...

pass through

Phoenix Coagulation Scoring

1 point each for platelets < 100 K/micro liter, INR > 1.3, D-dimer > 2 mg/L FEU, and fibrinogen < 100 mg/dL, with a max total score of 2.
