Drug TypeΒΆ

Drugs can be administered in different contexts, and this element captures information about this.

enum DrugType {
    UNKNOWN_DRUG_TYPE = 0;
    PRESCRIPTION = 1;
    EHR_MEDICATION_LIST = 2;
    ADMINISTRATION_RELATED_TO_PROCEDURE = 3;
}

This element does not intend to capture the medical reason for administering a treatment. Instead, it records the context in which the medication is administered. It is assumed that medications recorded on the medication list of an electronic health record (EHR) are likely to have been actually administered as prescribed. If a prescription is given for outpatient use, it is less likely that the medication will be taken exactly as prescribed (Osterberg L, Adherence to medication. N Engl J Med. 2005). Finally, medications may be given to conduct a medical procedure such as a local anesthetic given before a skin biopsy or a sedative given to perform a bronchoscopy.
