| - | * Observations differ from Measurements in that they do not require a standardized test or some other activity to generate clinical fact. Typical observations are medical history, family history, the stated need for certain treatment, social circumstances, lifestyle choices, healthcare utilization patterns, etc. If the generation clinical facts requires a standardized testing such as lab testing or imaging and leeds to a standardized result, the data item is recorded in the MEASUREMENT table. If the clinical fact observed determines a sign, symptom, diagnosis of a disease or other medical condition, it is recorded in the CONDITION_OCCURRENCE table. | + | * Observations differ from Measurements in that they do not require a standardized test or some other activity to generate clinical fact.

| * Valid Observation Concepts are not enforced to be from any domain. They still should be Standard Concepts, and they typically belong to the "Observation" or sometimes "Measurement" domain. | * Valid Observation Concepts are not enforced to be from any domain.

| * Observation can be stored as attribute value pairs, with the attribute as the Observation Concept and the value representing the clinical fact. This fact can be a Concept (stored in value_as_concept), a numerical value (value_as_number) or a verbatim string (value_as_string). Even though Observations do not have an explicit result, the clinical fact can be stated separately from the type of Observation in the value_as_ fields. | * Observation can be stored as attribute value pairs, with the attribute as the Observation Concept and the value representing the clinical fact.
