Drug exposure duration Overall

This shows the drug exposure duration of the drug records summarised on ingredient level. The drug exposure duration is estimated through (drug_exposure_end_date - drug_exposure_start_date + 1) for every individual drug exposure record.

datatable(acetaminophen_checks$drugExposureDurationOverall,
  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.
n_non_negative_days Number of drug records with a duration of one day or more.
n_negative_days Number of drug records with a negative duration (i.e. drug exposure start date after drug exposure end date).
proportion_negative_days Proportion of drug records with a negative duration
minimum_drug_exposure_days Minimum drug exposure duration
q05_drug_exposure_days 5th quantile of drug exposure duration
q10_drug_exposure_days 10th quantile of drug exposure duration
q25_drug_exposure_days 25th quantile of drug exposure duration
median_drug_exposure_days Median drug exposure duration
q75_drug_exposure_days 75th quantile of drug exposure duration
q90_drug_exposure_days 90th quantile of drug exposure duration
q95_drug_exposure_days 95th quantile of drug exposure duration
maximum_drug_exposure_days Maximum drug exposure duration
result_obscured TRUE if count has been suppressed due to being below the minimum cell count, otherwise FALSE.

Drug exposure duration by drug concept

This shows the drug exposure duration on the drug concept level. The drug exposure duration is estimated through (drug_exposure_end_date - drug_exposure_start_date + 1) for every individual drug exposure record. 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.
