Quantity Overall

This shows the quantity of the drug records summarised on ingredient level. The quantity is not a required field, but it is a most useful field. How the quantity is filled depends on the drug strength pattern. For quantified drugs (where the denominator_value is not missing), the quantity identifies the number of packages / items (in case of multiple dose packages). However, in case of non-quantified drugs (where the denominator_value is missing), the quantity identifies the volume / total number of actuations or others dispensed / prescribed.

datatable(acetaminophen_checks$drugQuantity,
  rownames = FALSE
)

Column	Description
ingredient_concept_id	Concept ID of ingredient.
ingredient	Name of drug ingredient.
n_records	Number of records for ingredient concept. If n_records is the same as n_sample this means that there are more records but the number was cut at the pre-specified sample number for efficiency reasons.
n_sample	The pre-specified maximum sample. If n_records is smaller than the sample it means that sampling was ignored because the total number of records was already too small.
n_person	Number of individuals.
minimum_drug_exposure_quantity	Minimum drug exposure quantity.
q05_drug_exposure_quantity	5th quantile for drug exposure quantity.
q10_drug_exposure_quantity	10th quantile for drug exposure quantity.
q25_drug_exposure_quantity	25th quantile for drug exposure quantity.
median_drug_exposure_quantity	Median drug exposure quantity.
q75_drug_exposure_quantity	75th quantile for drug exposure quantity.
q90_drug_exposure_quantity	90th quantile for drug exposure quantity.
q95_drug_exposure_quantity	95th quantile for drug exposure quantity.
maximum_drug_exposure_quantity	Maximum drug exposure quantity.
result_obscured	TRUE if count has been suppressed due to being below the minimum cell count, otherwise FALSE.

Quantity by concept

This shows the quantity of the drug records on the drug concept level. The quantity is not a required field, but it is a most useful field. How the quantity is filled depends on the drug strength pattern. For quantified drugs (where the denominator_value is not missing), the quantity identifies the number of packages / items (in case of multiple dose packages). However, in case of non-quantified drugs (where the denominator_value is missing), the quantity identifies the volume / total number of actuations or others dispensed / prescribed. The tables are identical to the overall just including two more columns at the beginning.

Column	Description
drug_concept_id	ID of the drug concept.
drug	Name of the drug concept.
