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: Marketed Product, 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.

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.

No Yes CONCEPT CONCEPT_ID NA NA NA
147 measurement unit_source_value No varchar(50) This field contains the exact value from the source data that represents the unit of measurement used. This value corresponds to a standardized CONCEPT_ID found in UNIT_CONCEPT_ID and in the 'Unit' domain within the Standardized Vocabularies. The original code is retained here for reference purposes. No No NA NA NA NA NA
148 measurement value_source_value No varchar(50) This field houses the verbatim result value of the Measurement from the source data . If both a continuous and categorical result are given in the source data such that both VALUE_AS_NUMBER and VALUE_AS_CONCEPT_ID are both included, store the verbatim value that was mapped to VALUE_AS_CONCEPT_ID here. No No NA NA NA NA NA
149 observation observation_id Yes integer The unique key given to an Observation record for a Person. Refer to the ETL for how duplicate Observations during the same Visit were handled.

151 observation observation_concept_id Yes integer The OBSERVATION_CONCEPT_ID field is recommended for primary use in analyses, and must be used for network studies. The CONCEPT_ID that the OBSERVATION_SOURCE_CONCEPT_ID maps to. There is no specified domain that the Concepts in this table must adhere to. The only rule is that records with Concepts in the Condition, Procedure, Drug, Measurement, or Device domains MUST go to the corresponding table. No Yes CONCEPT CONCEPT_ID NA NA NA
152 observation observation_date Yes date The date of when the Observation was obtained. Depending on what the Observation represents this could be the date of a lab test, the date of a survey, or the date a patient's family history was taken. For some observations the ETL may need to make a choice as to which date to choose. No No NA NA NA NA NA
165 observation unit_source_value No varchar(50) This field houses the verbatim value from the source data representing the unit of the Observation that occurred. This code is mapped to a Standard Condition Concept in the Standardized Vocabularies and the original code is stored here for reference. No No NA NA NA NA NA
166 observation qualifier_source_value No varchar(50) This field houses the verbatim value from the source data representing the qualifier of the Observation that occurred. This code is mapped to a Standard Condition Concept in the Standardized Vocabularies and the original code is stored here for reference. No No NA NA NA NA NA
167 death person_id Yes integer NA NA No Yes PERSON PERSON_ID NA NA NA
168 death death_date Yes date The date the person was deceased. If the precise date include day or month is not known or not allowed, December is used as the default month, and the last day of the month the default day. For additional conventions related to this field, please refer to the [THEMIS repository](https://ohdsi.github.io/Themis/tag_death_date.html). No No NA NA NA NA NA
169 death death_datetime No datetime NA If you have date and time of death, populate death_datetime, otherwise leave NULL No No NA NA NA NA NA
170 death death_type_concept_id No integer This is the provenance of the death record, i.e., where it came from. It is possible that an administrative claims database would source death information from a government file so do not assume the Death Type is the same as the Visit Type, etc. Use the type concept that reflects the source of the death record. [Accepted Concepts](https://athena.ohdsi.org/search-terms/terms?domain=Type+Concept&standardConcept=Standard&page=1&pageSize=15&query=). A more detailed explanation of each Type Concept can be found on the [vocabulary wiki](https://github.com/OHDSI/Vocabulary-v5.0/wiki/Vocab.-TYPE_CONCEPT). No Yes CONCEPT CONCEPT_ID Type Concept NA NA
171 death cause_concept_id No integer This is the Standard Concept representing the Person's cause of death, if available. There is no specified domain for this concept, just choose the Standard Concept Id that best represents the person's cause of death. No Yes CONCEPT CONCEPT_ID NA NA NA
189 note_nlp note_id Yes integer This is the NOTE_ID for the NOTE record the NLP record is associated to. NA No No NA NA NA NA NA
190 note_nlp section_concept_id No integer NA The SECTION_CONCEPT_ID should be used to represent the note section contained in the NOTE_NLP record. These concepts can be found as parts of document panels and are based on the type of note written, i.e. a discharge summary. These panels can be found as concepts with the relationship 'Subsumes' to CONCEPT_ID [45875957](https://athena.ohdsi.org/search-terms/terms/45875957). No Yes CONCEPT CONCEPT_ID NA NA NA
191 note_nlp snippet No varchar(250) A small window of text surrounding the term NA No No NA NA NA NA NA
192 note_nlp "offset" No varchar(50) Character offset of the extracted term in the input note NA No No NA NA NA NA NA
193 note_nlp lexical_variant Yes varchar(250) Raw text extracted from the NLP tool. NA No No NA NA NA NA NA
194 note_nlp note_nlp_concept_id No integer NA NA No Yes CONCEPT CONCEPT_ID NA NA NA
195 note_nlp note_nlp_source_concept_id No integer NA NA No Yes CONCEPT CONCEPT_ID NA NA NA
231 care_site care_site_name No varchar(255) The name of the care_site as it appears in the source data NA No No NA NA NA NA NA
232 care_site place_of_service_concept_id No integer This is a high-level way of characterizing a Care Site. Typically, however, Care Sites can provide care in multiple settings (inpatient, outpatient, etc.) and this granularity should be reflected in the visit. Choose the concept in the visit domain that best represents the setting in which healthcare is provided in the Care Site. If most visits in a Care Site are Inpatient, then the place_of_service_concept_id should represent Inpatient. If information is present about a unique Care Site (e.g. Pharmacy) then a Care Site record should be created. [Accepted Concepts](https://athena.ohdsi.org/search-terms/terms?domain=Visit&standardConcept=Standard&page=2&pageSize=15&query=). For information about how to populate this field please see the [THEMIS Conventions](https://ohdsi.github.io/Themis/tag_place_of_service.html). No Yes CONCEPT CONCEPT_ID NA NA NA
233 care_site location_id No integer The location_id from the LOCATION table representing the physical location of the care_site. NA No Yes LOCATION LOCATION_ID NA NA NA
234 care_site care_site_source_value No varchar(50) The identifier of the care_site as it appears in the source data. This could be an identifier separate from the name of the care_site. NA No No NA NA NA NA NA
235 care_site place_of_service_source_value No varchar(50) NA Put the place of service of the care_site as it appears in the source data. No No NA NA NA NA NA
236 provider provider_id Yes integer It is assumed that every provider with a different unique identifier is in fact a different person and should be treated independently. This identifier can be the original id from the source data provided it is an integer, otherwise it can be an autogenerated number. Yes No NA NA NA NA NA
237 provider provider_name No varchar(255) NA This field is not necessary as it is not necessary to have the actual identity of the Provider. Rather, the idea is to uniquely and anonymously identify providers of care across the database. No No NA NA NA NA NA
