The goal of DrugExposureDiagnostics is to summarise ingredient specific drug exposure data in the OMOP CDM.

Installation

You can install the DrugExposureDiagnostics from CRAN like this:

install.packages("DrugExposureDiagnostics")

or install the development version:

install.packages("remotes")
remotes::install_github("darwin-eu/DrugExposureDiagnostics")

Example use

Let´s look at the ingredient acetaminophen (https://athena.ohdsi.org/search-terms/terms/1125315).

We can run all the checks available in ´DrugExposureDiagnostics´ using the ´executeChecks´ function.

all_checks <- executeChecks(cdm = cdm, 
                            ingredients = 1125315, 
                            checks = c("missing", "exposureDuration", "type", "route", "sourceConcept", "daysSupply", 
                                       "verbatimEndDate", "dose", "sig", "quantity", "diagnosticsSummary"))
#> population after earliestStartDate smaller than sample, sampling ignored
#> ℹ The following estimates will be computed:
#> • daily_dose: count_missing, percentage_missing, mean, sd, min, q05, q25,
#>   median, q75, q95, max
#> ! Table is collected to memory as not all requested estimates are supported on
#>   the database side
#> → Start summary of data, at 2024-06-12 14:48:26.801546
#> 
#> ✔ Summary finished, at 2024-06-12 14:48:26.97046

The output is a list which contains the following set of tibbles:

names(all_checks)

The first item contains information on the concept ids that are used in the database for a given ingredient.

Other tibbles then contain information from the various checks performed.

For example, we can see a summary of missingness for the ingredient-related records in the drug exposure table, both overall and by concept.
