Data Element Information
Use Case Description(s)
Use Case Description	Disease reporting to public health relies on data from the EHR for identification of reportable events and to provide critical information used in confirming a diagnosis, understanding severity and classifying a case of disease that requires public health intervention for prevention, treatment, control, and outbreak identification and response. The specimen collection date is of particular importance for public health in understanding when laboratory confirmable evidence of a disease process was present in the patient. Specimen type and specimen site provides information useful in interpreting laboratory findings to determine severity and transmissibility.
Estimate the breadth of applicability of the use case(s) for this data element	Over 3000 public health agencies in the US would use these data elements for disease surveillance and control activities.

APHL comment to add into USCDIV2

This data element is critical in supporting specimentype information, when more generic types are submitted - for example a joint fuild sample or a tissue sample - rather than supporting a lot of pre-coordinated (and still potentially not detailed enough specimen types) use of source site allows for a clear identification of the sample's location - critical for treating infections and cancer for example. It has been included in V2 messages for a long time (OBR-15.4) and is an RE element in ELR R1.
