# | Column | Type | Notes |
1 | eid | integer | A foreign key identifier to the Person about whom the measurement was recorded. |
2 | measurement_concept_id | integer | A foreign key to the standard measurement concept identifier in the Standardized Vocabularies. |
3 | measurement_date | date | The date of the Measurement. |
4 | measurement_datetime | timestamp | The date and time of the Measurement. (Some database systems don't have a datatype of time. To accomodate all temporal analyses, datatype datetime can be used (combining measurement_date and measurement_time)Relevant Forum Discussion |
5 | measurement_id | integer | A unique identifier for each Measurement. |
6 | measurement_source_concept_id | integer | A foreign key to a Concept in the Standard Vocabularies that refers to the code used in the source. |
7 | measurement_source_value | string | The Measurement name as it appears in the source data. This code is mapped to a Standard Concept in the Standardized Vocabularies and the original code is stored here for reference. |
8 | measurement_time | timestamp | A foreign key to the predefined Concept in the Standardized Vocabularies reflecting the provenance from where the Measurement record was recorded. |
9 | measurement_type_concept_id | integer | |
10 | operator_concept_id | integer | A foreign key identifier to the predefined Concept in the Standardized Vocabularies reflecting the mathematical operator that is applied to the value_as_number. Operators are <, ?, =, ?, >. |
11 | provider_id | integer | A foreign key to the provider in the PROVIDER table who was responsible for initiating or obtaining the measurement. |
12 | range_high | float | The upper limit of the normal range of the Measurement. The upper range is assumed to be of the same unit of measure as the Measurement value. |
13 | range_low | float | The lower limit of the normal range of the Measurement result. The lower range is assumed to be of the same unit of measure as the Measurement value. |
14 | unit_concept_id | integer | A foreign key to a Standard Concept ID of Measurement Units in the Standardized Vocabularies. |
15 | unit_source_value | string | The source code for the unit as it appears in the source data. This code is mapped to a standard unit concept in the Standardized Vocabularies and the original code is stored here for reference. |
16 | value_as_concept_id | integer | A foreign key to a Measurement result represented as a Concept from the Standardized Vocabularies (e.g., positive/negative, present/absent, low/high, etc.). |
17 | value_as_number | float | A Measurement result where the result is expressed as a numeric value. |
18 | value_source_value | string | The source value associated with the content of the value_as_number or value_as_concept_id as stored in the source data. |
19 | visit_detail_id | integer | |
20 | visit_occurrence_id | integer | A foreign key to the Visit in the VISIT_OCCURRENCE table during which the Measurement was recorded. |
