Proposed Change for Over-the-Counter ELR HL7 Messages

Datapult has heard from a jurisdiction that they are having issues validating the date when the specimen collection date/time (OBR-7, OBX-14, SPM-17) and the test result date/time (OBX-19) are the same. As you are aware, over-the-counter (OTC) tests are typically reported by the patient via an app that does not ask the time of specimen collection. The reporting system will typically only have the date/time that the patient reported the result in the app. This date/time is then used in OBR-7, OBX-14, OBX-19, SPM-17, and SPM-18 (Specimen Received Date/Time).
 
With this in mind, we propose making some changes to the way times are sent for OTC HL7 messages. Instead of using the same date/time for specimen collection, specimen received, and test result date/time, we propose using “0000” for OBR-7, OBX-14 (if populated), and SPM-17 as the specimen collection date/time is actually unknown. This is in line with the guidance in the HL7 ELR R1 standard. We do not propose making any changes to the date/time in OBX-19 and SPM-18 for OTC messages.  
 
Please let us know if this proposed change would adversely affect your system. We also plan on discussing on the Open ELR call this Thursday.
 
Thanks,

“0000” for OBR-7, OBX-14 (if populated), and SPM-17 would cause validation errors in our system. I think we can reasonably make the assumption that for OTC tests, the date remains the same for all relevant date variables.

Agree. With rare exceptions, OTC tests usually have the same dates for these. We can handle if dates are the same.

Agree.  '0000' would cause errors for us but can handle if the dates are the same.

Thank you for the feedback. Based on this, we will work with the jurisdiction to find an alternative.

'0000' would cause errors for NY. We have no issues with the dates being the same.



Thanks.
