Data Element Information
Data Element Description This data element is used to indicate whether a specimen was unacceptable for testing. It is proposed to contain two codes, the first representing the condition of the specimen and the second representing the reason for rejection (if appropriate).
Use Case Description(s)
Use Case Description Reference Range:
This data element aligns with CLIA’s Reference Range reporting requirement. The CLIA requirements are required for laboratory reporting and should be used as the basis for laboratory and public health reporting standards. The primary use cases for this data element in the USCDI are routine communication of laboratory results to healthcare providers and public health agencies in support of test result interpretation. These use cases are similar to existing use cases for OBX-7 that are described in detail in the following documentation.
 HL7 Version 2.5.1 Implementation Guide: Laboratory Results Interface, Release 1 STU Release 3 - US Realm (https://www.hl7.org/implement/standards/product_brief.cfm?product_id=279)
 HL7 Version 2.5.1 Implementation Guide: Electronic Laboratory Reporting to Public Health, Release 1 (US Realm) (https://www.hl7.org/implement/standards/product_brief.cfm?product_id=98)
 HL7 Version 2.5.1 Implementation Guide: Orders and Observations; Interoperable Laboratory Result Reporting to EHR, Release 1 (https://www.hl7.org/implement/standards/product_brief.cfm?product_id=94).

Name and Address of Laboratory Location:
This data element aligns with CLIA’s requirement to report the name and address of the laboratory location where the test was performed. The CLIA-defined requirements are required for laboratory reporting and should be used as the basis for laboratory and public health reporting standards. The main use case is routine communication of laboratory results to healthcare providers and public health agencies in support of test result interpretation.

Condition and Disposition of Specimens:
This data element aligns align with CLIA’s requirement to report any information regarding the condition and disposition of specimens that do not meet the laboratory's criteria for acceptability. The CLIA-defined requirements are required for laboratory reporting and should be used as the basis for laboratory and public health reporting standards. The main use case is routine communication of laboratory results to healthcare providers and public health agencies in support of test result interpretation.

Test Result Harmonization Status:
The primary use case for harmonization status is in sharing data for clinical interpretation and use. If a test result from an external site has a harmonization status matching local tests, the harmonized results could be displayed in the same line of a flow sheet, and trended and processed with local results. A non-harmonized result would not be clinically compatible with local results and should be displayed and processed separately. In a public health setting, harmonized results could be grouped for surveillance processing, statistical analysis, and machine learning applications. Non-harmonized results should be kept separate.
Estimate the breadth of applicability of the use case(s) for this data element Reference Range:
The data element would be used with all laboratory result messages sent between laboratories and data recipients including public health agencies, and in messages sent between provider organizations that contained laboratory results. Since there are around 330,000 CLIA-certified laboratories in the United States that are information sources, the usage floor including laboratories and their communication partners would be substantially above that number.

Name and Address of Laboratory Location:
The data element would be used with all laboratory result messages sent between laboratories and data recipients including public health agencies, and in messages sent between provider organizations that contained laboratory results. Since there are around 330,000 CLIA-certified laboratories in the United States that are information sources, the usage floor including laboratories and their communication partners would be substantially above that number.

Condition and Disposition of Specimens:
The data element would be used with all laboratory result messages sent between laboratories and data recipients including public health agencies, and in messages sent between provider organizations that contained laboratory results. Since there are around 330,000 CLIA-certified laboratories in the United States, there is a usage floor of approximately 660,000 organizations assuming each laboratory sends data to at least one other organization.

Test Result Harmonization Status:
Because the data element would be needed to meet any current or future clinical interoperability requirements, the CAP anticipates that it would become a routine component of laboratory result reporting. Since there are around 330,000 CLIA-certified laboratories in the United States that are information sources, the usage floor including laboratories and their communication partners would be substantially above that number.
Healthcare Aims
  • Improving patient experience of care (quality and/or satisfaction)
  • Improving the health of populations
  • Reducing the cost of care
  • Improving provider experience of care
Maturity of Use and Technical Specifications for Data Element
Applicable Standard(s) These proposed elements are a work in progress and the CAP urges that the vocabulary standards listed be considered for a future version of USCDI:

Reference Range:
The CAP proposes that the content of this data element follow the OBX-7 field from the HL7 2.5.1 standard. The CAP supports the use of the HL7 2.5.1 standard because the standard was designed to help laboratories comply with CLIA requirements. For numerical values, the CAP also proposes the Unified Code for Units of Measure (UCUM) standard. The CAP supports the use of the UCUM standard because it is well-established and because a common standard for units of measure will reduce errors related to translation of units of measure from one system to another.

Name and Address of Laboratory Location:
In lieu of a non-standard and inefficient textual description of a name and address, the CAP is proposing the use of the CLIA identification number as the data element content. All laboratories performing clinical testing have a CLIA identification number and are required to be able to report it, so the use of this number is not burdensome. The name and location of a laboratory can be determined quickly from the CLIA number using available online resources (for example, https://www.cdc.gov/clia/LabSearch.html).

Condition & Disposition of Specimens:
The CAP proposes the use of SNOMED CT for data element content. SNOMED CT is a relatively complete, well-curated, and actively-managed medical ontology that has excellent coverage of concepts appropriate for description of laboratory specimens, specimen sources, and conditions, and supports a rich array of hierarchical and other concept relationships.

Test Result Harmonization Status:
This is the first proposal of a harmonization status data element, and examples do not exist in other health data standards. Recently the ISO defined standard methods for harmonizing laboratory tests (see ISO 17511:2020 and 21151:2020). The CAP proposes development of a standard representation of these methods as content for this data element.

The contents of these fields are HL7 code sets, with extensions allowed. The CAP is proposing similar concepts but using SNOMED CT for data representation.

CAP Comment on Specimen Condition and Disposition

  • Data Class: Laboratory
  • Data Element: Specimen Condition and Disposition
  • CAP Comment: The CAP applauds the ONC’s decision to add this data element to USCDI v4, as this data element includes any information regarding the condition and disposition of specimens that do not meet the laboratory's criteria for acceptability relevant to the performance or non-performance of a test as required by CLIA. The CAP recommends that SNOMED CT—which was in the original submission for this data element—be added as the vocabulary standard for this data element.

THIA Comment on Laboratory: Specimen Condition and Disposition

The Texas Health Informatics Alliance (THIA) Policy and Standards Working Group supports the proposal for specimen condition and disposition. Many institutions already have a process in practice, but there is value in standardization of this practice. Standardization means there would be data on prevalence and occurrence, which is important for quality assurance purposes.
