Drug Time Between

Run the drug time-between check

library(DrugExposureDiagnostics)
cdm <- mockDrugExposure()
result <- executeChecks(
  cdm = cdm,
  checks = "daysBetween",
  sample = 10
)

Drug time between overall

This check calculates the number of days between the start dates of consecutive drug exposure records for each person, summarised at the ingredient level. Only people with at least two records in the relevant group contribute an interval.

sample is not used for this check. Sampling individual records would remove records from a person’s exposure sequence and create artificial gaps. Therefore, even when a sample size is supplied to executeChecks(), the time-between check uses all eligible records after any earliestStartDate, concept, and exposure-type restrictions have been applied. The other requested checks continue to use the record-level sample.

Column Description
ingredient_concept_id Concept ID of the ingredient.
ingredient Name of the drug ingredient.
n_records Number of consecutive-record intervals included in the summary. This is not the number of original drug exposure records.
n_person Number of people contributing at least one consecutive-record interval.
minimum_time_between_days Minimum number of days between consecutive drug exposure start dates.
q05_time_between_days 5th percentile of the time between consecutive records.
q10_time_between_days 10th percentile of the time between consecutive records.
q25_time_between_days 25th percentile of the time between consecutive records.
median_time_between_days Median number of days between consecutive records.
q75_time_between_days 75th percentile of the time between consecutive records.
q90_time_between_days 90th percentile of the time between consecutive records.
q95_time_between_days 95th percentile of the time between consecutive records.
maximum_time_between_days Maximum number of days between consecutive drug exposure start dates.
result_obscured TRUE if counts have been suppressed because they are below the minimum cell count; otherwise FALSE.

There is no n_sample column because this check does not use a record-level sample.

Drug time between by drug concept

When byConcept = TRUE (the default), drugTimeBetweenByConcept provides the same summary separately for each drug concept. Consecutive records are determined within person and drug concept.

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