77 DRUG_EXPOSURE drug_exposure_id Yes integer The unique key given to records of drug dispensings or administrations for a person. Refer to the ETL for how duplicate drugs during the same visit were handled. Each instance of a drug dispensing or administration present in the source data should be assigned this unique key. In some cases, a person can have multiple records of the same drug within the same visit. It is valid to keep these duplicates and assign them individual, unique, DRUG_EXPOSURE_IDs, though it is up to the ETL how they should be handled. Yes No
78 DRUG_EXPOSURE person_id Yes integer The PERSON_ID of the PERSON for whom the drug dispensing or administration is recorded. This may be a system generated code. No Yes PERSON PERSON_ID
79 DRUG_EXPOSURE drug_concept_id Yes integer The DRUG_CONCEPT_ID field is recommended for primary use in analyses, and must be used for network studies. This is the standard concept mapped from the source concept id which represents a drug product or molecule otherwise introduced to the body. The drug concepts can have a varying degree of information about drug strength and dose. This information is relevant in the context of quantity and administration information in the subsequent fields plus strength information from the DRUG_STRENGTH table, provided as part of the standard vocabulary download. The CONCEPT_ID that the DRUG_SOURCE_VALUE maps to. The concept id should be derived either from mapping from the source concept id or by picking the drug concept representing the most amount of detail you have. Records whose source values map to standard concepts with a domain of Drug should go in this table. When the Drug Source Value of the code cannot be translated into Standard Drug Concept IDs, a Drug exposure entry is stored with only the corresponding SOURCE_CONCEPT_ID and DRUG_SOURCE_VALUE and a DRUG_CONCEPT_ID of 0. 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.

80 DRUG_EXPOSURE drug_exposure_start_date Yes date Use this date to determine the start date of the drug record. Valid entries include a start date of a prescription, the date a prescription was filled, or the date on which a Drug administration was recorded. It is a valid ETL choice to use the date the drug was ordered as the DRUG_EXPOSURE_START_DATE. No No
81 DRUG_EXPOSURE drug_exposure_start_datetime No datetime This is not required, though it is in v6. If a source does not specify datetime the convention is to set the time to midnight (00:00:0000) No No
82 DRUG_EXPOSURE drug_exposure_end_date Yes date The DRUG_EXPOSURE_END_DATE denotes the day the drug exposure ended for the patient. If this information is not explicitly available in the data, infer the end date using the following methods:<br><br> 1. Start first with duration or days supply using the calculation drug start date + days supply -1 day. 2. Use quantity divided by daily dose that you may obtain from the sig or a source field (or assumed daily dose of 1) for solid, indivisibile, drug products. If quantity represents ingredient amount, quantity divided by daily dose * concentration (from drug_strength) drug concept id tells you the dose form. 3. If it is an administration record, set drug end date equal to drug start date. If the record is a written prescription then set end date to start date + 29. If the record is a mail-order prescription set end date to start date + 89. The end date must be equal to or greater than the start date. Ibuprofen 20mg/mL oral solution concept tells us this is oral solution. Calculate duration as quantity (200 example) * daily dose (5mL) /concentration (20mg/mL) 200*5/20 = 50 days.

95 DRUG_EXPOSURE visit_detail_id No integer The VISIT_DETAIL record during which the drug exposure occurred. For example, if the person was in the ICU at the time of the drug administration the VISIT_OCCURRENCE record would reflect the overall hospital stay and the VISIT_DETAIL record would reflect the ICU stay during the hospital visit. Same rules apply as for the VISIT_OCCURRENCE_ID. No Yes VISIT_DETAIL VISIT_DETAIL_ID
96 DRUG_EXPOSURE drug_source_value No varchar(50) This field houses the verbatim value from the source data representing the drug exposure that occurred. For example, this could be an NDC or Gemscript code. This code is mapped to a Standard Drug Concept in the Standardized Vocabularies and the original code is stored here for reference. No No
97 DRUG_EXPOSURE drug_source_concept_id No integer This is the concept representing the drug source value and may not necessarily be standard. This field is discouraged from use in analysis because it is not required to contain Standard Concepts that are used across the OHDSI community, and should only be used when Standard Concepts do not adequately represent the source detail for the Drug necessary for a given analytic use case.
