Flag opioid deaths according to ISW7 rules

Given an MCOD dataframe, will apply ISW7 rules to flag opioid deaths for both ICD9 and ICD10 codes. Expects you to run unite_records() first. If you don't, it will do so, but will remove that columns by default. Change keep_cols = TRUE to keep it.

Usage

flag_opioid_deaths(processed_df, year = NULL, keep_cols = FALSE)

Arguments

processed_df

processed dataframe

year

if NULL, will attempt to detect

keep_cols

keep intermediate columns

Value

new dataframe with a binary opioid_death column

Note

"Any opioid" includes T40.6 ("other and unspecified narcotics"), following ISW7 and NCHS. Per the ISW7 (2012) Appendix B1 footnote, T40.6 can capture non-opioids (e.g., cocaine) in some jurisdictions.

Examples

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