Create Exposure and Optional Response Groups from Diagnoses

Source: R/population_classification.R
classify_population.Rd

This function identifies individuals with exposure diagnoses (and optionally response diagnoses) based on ICD-10/9/8 codes and selected registry sources. It returns a dataset of grouped individuals with exposure (and optionally response) classifications, diagnosis dates, and relevant metadata. Function searches first diagnose date, which is given for exposure/response diagnose date.

Usage

classify_population(
  exposure_icd10 = "",
  exposure_icd9 = "",
  exposure_icd8 = "",
  exposure_src = c(""),
  response_icd10 = NULL,
  response_icd9 = NULL,
  response_icd8 = NULL,
  response_src = c(""),
  data_population = population,
  data_diagnoses = diagnoses,
  runtime_shiny = FALSE
)

Arguments

exposure_icd10

A character vector of ICD-10 codes (regex-supported) to identify exposure group.

exposure_icd9

A character vector of ICD-9 codes (regex-supported) to identify exposure group.

exposure_icd8

A character vector of ICD-8 codes (regex-supported) to identify exposure group.

exposure_src

A character vector of registry sources used to search for exposure diagnoses.

response_icd10

Optional character vector of ICD-10 codes for response group (default: NULL).

response_icd9

Optional character vector of ICD-9 codes for response group (default: NULL).

response_icd8

Optional character vector of ICD-8 codes for response group (default: NULL).

response_src

A character vector of registry sources used to search for response diagnoses.

data_population

A data frame of the target population (default: `population`).

data_diagnoses

A data frame of diagnoses (default: `diagnoses`).

runtime_shiny

Logical; if TRUE and run inside a Shiny app, shows progress bar (default: FALSE).

Value

A data frame with exposure (and optionally response) group classifications and metadata, including ID, birth/death/migration dates, diagnosis info, and binary indicators for exposure/response.

Examples

classify_population(exposure_icd10 = "I21", exposure_src = "hilmo")
#> Error in classify_population(exposure_icd10 = "I21", exposure_src = "hilmo"): object 'diagnoses' not found
classify_population(exposure_icd10 = "F32", response_icd10 = "I21")
#> Error in classify_population(exposure_icd10 = "F32", response_icd10 = "I21"): object 'diagnoses' not found
