Description

OMOP Common Data Model (CDM) Drug Exposure The 'Drug' domain captures records about the utilization of a Drug when ingested or otherwise introduced into the body. A Drug is a biochemical substance formulated in such a way that when administered to a Person it will exert a certain physiological effect. Drugs include prescription and over-the-counter medicines, vaccines, and large-molecule biologic therapies. Radiological devices ingested or applied locally do not count as Drugs. Drug Exposure is inferred from clinical events associated with orders, prescriptions written, pharmacy dispensings, procedural administrations, and other patient-reported information, for example: The 'Prescription' section of an EHR captures prescriptions written by physicians or from electronic ordering systems; The 'Medication list' section of an EHR for both non-prescription products and medications prescribed by other providers; Prescriptions filled at dispensing providers such as pharmacies, and then captured in reimbursement claim systems; Drugs administered as part of a Procedure, such as chemotherapy or vaccines. The Observational Medical Outcomes Partnership (OMOP) was a public-private partnership established to inform the appropriate use of observational healthcare databases for studying the effects of medical products. © 2014 Observational Health Data Sciences and Informatics. This work is based on work by the Observational Medical Outcomes Partnership (OMOP) and used under license from the FNIH at http://omop.fnih.org/publiclicense. Version updated on 12.02.2019, from https://github.com/OHDSI/CommonDataModel/wiki/DRUG_EXPOSURE. The Drug Concept with the most detailed content of information is preferred during the mapping process. These are indicated in the CONCEPT_CLASS_ID field of the Concept and are recorded in the following order of precedence: 'Branded Pack', 'Clinical Pack', 'Branded Drug', 'Clinical Drug', 'Branded Drug Component', 'Clinical Drug Component', 'Branded Drug Form', 'Clinical Drug Form', and only if no other information is available 'Ingredient'. Note: If only the drug class is known, the DRUG_CONCEPT_ID field should contain 0. A Drug Type is assigned to each Drug Exposure to track from what source the information was drawn or inferred from. The valid CONCEPT_CLASS_ID for these Concepts is 'Drug Type'.

Description

A foreign key that refers to a Standard Concept identifier in the Standardized Vocabularies belonging to the 'Drug' domain. Valid Concepts for the DRUG_CONCEPT_ID field belong to the 'Drug' domain. Most Concepts in the Drug domain are based on RxNorm, but some may come from other sources.

Drug exposure end date
Description

The end date for the current instance of Drug utilization. Depending on different sources, it could be a known or an inferred date and denotes the last day at which the patient was still exposed to Drug. The DRUG_EXPOSURE_END_DATE denotes the day the drug exposure ended for the patient. This could be that the duration of DRUG_SUPPLY was reached (in which case DRUG_EXPOSURE_END_DATETIME = DRUG_EXPOSURE_START_DATETIME + DAYS_SUPPLY -1 day), or because the exposure was stopped (medication changed, medication discontinued, etc.)

Days supply
Description

The number of days of supply of the medication as prescribed. This reflects the intention of the provider for the length of exposure. When the native data suggests a drug exposure has a days supply less than 0, drop the record as unknown if a person has received the drug or not (THEMIS issue #24). If a patient has multiple records on the same day for the same drug or procedures the ETL should not de-dupe them unless there is probable reason to believe the item is a true data duplicate.

Route concept ID
Description

A foreign key that refers to a Standard Concept identifier in the Standardized Vocabularies reflecting the route of administration and belonging to the 'Route' domain. The ROUTE_CONCEPT_ID refers to a Standard Concepts of the 'Route' domain. Note: Route information can also be inferred from the Drug product itself by determining the Drug Form of the Concept, creating some partial overlap of the same type of information. Therefore, route information should be stored in DRUG_CONCEPT_ID (as a drug with corresponding Dose Form). The ROUTE_CONCEPT_ID could be used for storing more granular forms e.g. 'Intraventricular cardiac'.
