Parameters for ATC Codes
ATC_parameters.RdA dataset containing parameters associated with ATC (Anatomical Therapeutic Chemical) codes used in the PRE2DUP-R package.
Format
A `data.frame` or `data.table` with one row per ATC code. Includes the following variables:
- partial_atc
Partial or full ATC code (character)
- lower_ddd_atc
Minimum commonly used daily dose (numeric, in DDDs)
- usual_ddd_atc
Usual daily dose (numeric, in DDDs)
- minimum_dur_atc
Minimum allowed treatment duration (numeric, in days)
- maximum_dur_atc
Maximum allowed treatment duration (numeric, in days)
Details
The ATC codes may be partial or complete; the program uses the closest match to the ATC code in the drug purchases. All ATC codes appearing in drug purchases must be included in the ATC parameters table, at least at a partial-code level. These parameters are used when package-specific information is not available.
