Creates a new column called heroin_present if opioid death involved heroin

Source: R/flag_heroin_present.R
flag_heroin_present.Rd

Heroin deaths were recorded in both ICD-9 and ICD-10 years. This creates a new column to flag when that death involved heroin and was an opioid death as defined by flag_opioid_death().

Usage

flag_heroin_present(
  processed_df,
  year = NULL,
  keep_cols = FALSE,
  opioid_deaths_only = TRUE
)

Arguments

processed_df

MCOD dataframe already processed

year

if NULL, will attempt to detect

keep_cols

keep intermediate columns

opioid_deaths_only

if `TRUE` (default) the flag fires only on opioid deaths (`opioid_death == 1`); if `FALSE`, it fires wherever the heroin code appears (including contributory-only records) and the caller is expected to `filter(opioid_death == 1)` themselves.

Value

a new dataframe with a binary heroin_present column

Examples

df <- data.frame(year = 2019, ucod = "X42", f_records_all = "T401 T400")
flag_heroin_present(df, year = 2019)
#>   year ucod f_records_all heroin_present
#> 1 2019  X42     T401 T400              1
