Here is a link to the USCDI V6 draft: United States Core Data for Interoperability (USCDI) - Draft Version 6.
In Draft V6, ASTP added 6 new data elements. The Unique Device Identifier has a possible impact on laboratory data. Of the substantive changes/updates that they highlight in their summary, these are the most important for laboratorians to be aware of:
Laboratory Order, Diagnostic Imaging Order, and Clinical Test Order would include LOINC as the applicable standard
Updated the applicable vocabulary to the latest versions of LOINC and SNOMED as of the publication of Draft USCDI v6
APHL’s draft comments on Draft V6
· Date/timestamps: ASTP’s current approach is to use a single procedure performance date/time element in USCDI to cover all lab relevant date/time, which include: Specimen collection date/time; Specimen received date time; Test performed date/time; Report released date/time. APHL raises the concern that most systems don’t model these observations as procedures. APHL recommends at a minimum adding data elements to capture Specimen Collection date/time (https://www.healthit.gov/isp/taxonomy/term/3256/level-0 ), Specimen receipt at the lab date/time (submitted to USCDI+ for the PH Lab Reporting Use case, but not available on the USCDI+ website yet), Laboratory Test performed data/time (https://www.healthit.gov/isp/taxonomy/term/2436/level-0 ), and Report released date/time (submitted to USCDI+ for the PH Lab Reporting Use case as a corellary to eCR report date element, but not available on the USCDI+ website yet https://uscdiplus.healthit.gov/uscdiplus?id=uscdi_record&table=x_g_sshh_uscdi_uscdi_elements&sys_id=04a7ba8a1b367d1094626318624bcbf3&view=sp ).
· Assigning Authority: APHL recommends ASTP include the assigning authority with ANY identifier data element (in all HL7 products this is part of the various supported identifier type data type). This comment applies to Identifier (), Specimen Identifier (https://www.healthit.gov/isp/taxonomy/term/3721/uscdi-v5 ), Medical Record Number (), and Medicare Patient Identifier. We recommend that the definitions for these data elements include the following language: "Alphanumeric value that uniquely identifies the patient's health record over time, at minimum within one organization, ideally at the national level, including a means to identify the organization or system that assigned it."
