Include only purchases of glucose lowering drugs (GLD)

But don't include glucose-lowering drugs that may be used for other conditions than diabetes like GLP-RAs or dapagliflozin/empagliflozin drugs. Since the diagnosis code data on pregnancies (see below) is insufficient to perform censoring prior to 1997, include_gld_purchases() only extracts dates from 1997 onward by default (if Medical Birth Register data is available to use for censoring, the extraction window can be extended).

Usage

include_gld_purchases(lmdb)

Arguments

lmdb

The lmdb register.

Value

The same type as the input data, default as a tibble::tibble(). Only rows with glucose lowering drug purchases are kept, plus some columns are renamed.

See the vignette("algorithm") for the logic used to filter these patients.

Examples

if (FALSE) { # \dontrun{
simulate_registers("lmdb", 1000)[[1]] |> include_gld_purchases()
} # }
