[Under review at this time]
When modeling an event, be sure to model the event itself and not the outcome of an event. The outcome of an event would be a finding or a disorder.
The Event hierarchy should not precoordinate periods of life/occurrence within the event concept.
Although Pharmaceutical / biologic product (product) and its descendants are considered valid values for the Causative agent (attribute) by the MRCM, they are not currently used as values for this attribute in the International Release. The only exception is 787859002 |Vaccine product (medicinal product)| and its descendants, which can be used as valid values for this attribute.
The allowed ranges will not prevent some incorrect modeling. Some allowed attributes have not yet been used for modeling in the Event domain. The planned QI project will review the modeling to ensure consistency of use the allowed attributes.
