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.

ASTP Evaluation Details
Each submitted Data Element has been evaluated based on the following criteria. The overall Level classification is a composite of the maturity based on these individual criteria. This information can be used to identify areas that require additional work to raise the overall classification level and consideration for inclusion in future versions of USCDI
Criterion #1
Maturity - Current Standards		 Level 2 - Data element is represented by a terminology standard or SDO-balloted technical specification or implementation guide.
Criterion #2
Maturity - Current Use 		Level 2 - Data element is captured, stored, or accessed in multiple production EHRs or other HIT modules from more than one developer.
Criterion #3
Maturity - Current Exchange		 Level 2 - Data element is electronically exchanged between more than two production EHRs or other HIT modules of different developers using available interoperability standards.
Criterion #4
Use Case(s) - Breadth of Applicability		 Level 0 - Use cases apply to a limited number of care settings or specialties, or data element represents a specialization of other, more general data elements.
Evaluation Comment This data element represents a specific type of existing USCDI data element Performance Time in the Procedures data class.

CAP Comment on Specimen collection date/time

Data Element: Specimen collection date/time

  • Description: The College of American Pathologists (CAP) supports the inclusion of this Level 2 data element into USCDI v4. While this is not a CLIA requirement, the specimen collection time defines the clinically applicable time of the result, which is crucial for correct interpretation of the result by care providers and correct response by public health agencies in emergency (eg, pandemic) preparedness and response settings. For future iterations of USCDI, we may recommend replacing this data element with two data elements corresponding to the OBX-14 and SPM-17 fields in HL7 2.5.1. The data elements should be named “Date/time of the observation” which is the name of OBX-14, and “Date/time of specimen collection,” which is a minor variation on the name of SPM-17. Date/time of the observation refers to the clinically-relevant date/time associated with the measurement. When there is testing of a specimen, HL7 2.5.1 specifies that the content of OBX-14 and SPM-17 should be identical. Having these two data elements allows for documentation of specimen collection time in rare cases where the clinically relevant time and specimen collection time might differ. The CAP may submit these new data elements for USCDI v5 in 2023.
  • Vocabulary Standard: The CAP recommends the value format from the SPM-17 field in HL7 2.5.1, which is a version of the Health Level Seven (HL7) standard that defines methods for transferring and sharing data between various healthcare systems and providers. The CAP supports the use of the HL7 2.5.1 standard because the standard was designed to help laboratories comply with CLIA requirements. HL7 2.5.1 SPM-17 is aligned with the ISO 8601 international standard for communicating date and time information.

APHL Comments on ISA 2022

APHL supports inclusion of this data element in the Laboratory class of USCDI V4 because it is a CLIA required element and represents the clinically relevant time of laboratory results, which means it provides the temporal context to the clinician.
