diff_comorbid: show the difference between two comorbidity mappings

In icd: Comorbidity Calculations and Tools for ICD-9 and ICD-10 Codes

Description

Compares two comorbidity to ICD code mappings. The results are returned invisibly as a list. Only those comorbidities with (case sensitive) overlapping names are compared.

Usage

diff_comorbid(
  x,
  y,
  all_names = NULL,
  x_names = NULL,
  y_names = NULL,
  show = TRUE,
  explain = TRUE
)

## S3 method for class 'list'
diff_comorbid(
  x,
  y,
  all_names = NULL,
  x_names = NULL,
  y_names = NULL,
  show = TRUE,
  explain = TRUE
)

Arguments

x	list of character vectors
y	list of character vectors
all_names	character vector of the comorbidity names
x_names	character vector of the comorbidity names from x to compare
y_names	character vector of the comorbidity names from y to compare
show	single logical value. The default is TRUE which causes a report to be printed.
explain	single logical value. The default is TRUE which means the differing codes are attempted to be reduced to their parent codes, in order to give a more succinct summary.

Value

A list, each item of which is another list containing the intersections and both asymmetric differences.

Methods (by class)

• list: Show difference between comorbidity maps with ICD-9 codes

Examples

# compare CHF for ICD-10 mappings from Elixhauser and AHRQ
diff_comorbid(icd10_map_elix, icd10_map_ahrq, show = FALSE)[["CHF"]]
## Not run: 
# default is to show the results in a human readable manner:
diff_result <- diff_comorbid(icd9_map_elix, icd9_map_ahrq)[["CHF"]]
# show differences for
# give full report on all comorbidities for these mappings
diff_result <- diff_comorbid(icd9_map_elix, icd9_map_ahrq, show = FALSE)

# the following outputs a summary to the console:
diff_comorbid(icd9_map_elix, icd9_map_ahrq)

## End(Not run)
