Numerator
Number of individuals ≥ 75 years of age as on 1 January in database with ≥ 5 chronically used medications with different ATC codes at the fourth level (e.g., A10BA) during the reference year. This means that a different medication should only be counted if it is not within the same ATC codes at the fourth level. Medication here refers to subgroups of chemicals classified by the World Health Organisation at the fourth level of the ATC classification system, 2017 version.
Denominator
Number of individuals ≥ 75 years of age at 1 January in database
Exclusions
Dermatologicals for topical usage are excluded of the count because these medications usually do not interact with other (systemic) medications. Antibiotics (i.e., ATC codes "J01") are also excluded because they are almost exclusively prescribed for acute infections
