Phoenix Immunologic Score

Description

Apply the Phoenix immunologic scoring based on ANC and ALC. This is only part of Phoenix-8 and not Phoenix.

Usage

phoenix_immunologic(anc = NA_real_, alc = NA_real_, data = parent.frame(), ...)

Arguments

anc

absolute neutrophil count; a numeric vector; units of 1,000 cells per cubic millimeter

alc

absolute lymphocyte count; a numeric vector; units of 1,000 cells per cubic millimeter

data

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

...

pass through

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.

Phoenix Immunologic Scoring

1 point if ANC < 0.500 or ALC < 1.000 (units are 1000 cells per cubic millimeter).

Examples


# using the example sepsis data set
# Expected units for ALC and ANC are 1000 cells per cubic millimeter

immu_example <- sepsis[c("pid", "anc", "alc")]
immu_example$score <- phoenix_immunologic(anc, alc, sepsis)
immu_example

# example data set with all possilbe immunologic scores
# Expected units for anc and alc are 1000 cells per cubic millimeter

DF <- expand.grid(anc = c(NA, 0.200, 0.500, 0.600),
                  alc = c(NA, 0.500, 1.000, 2.000))
phoenix_immunologic(anc = anc, alc = alc, data = DF)
