Data Element Information
Use Case Description(s)
Use Case Description Actively monitoring diseases, making decisions about public health threats, identifying trends in healthcare services utilization and other public health matters depend on accessible and accurate data. EHRs are a data source that can provide timely and relevant data beyond its use by health care providers. EHR data, if made more available for public health professionals and researchers, can lead to more rapid disease detection, tracking, and treatment and innovation in healthcare delivery.

Laboratory information, including the test code, test performed date, result status, result value and the result date, are important to multiple public health reporting and research use cases to track and analyze information about treatment for various health conditions.

The Making EHR Data More Available for Research and Public Health (MedMorph) project's goal is to create a reliable, scalable, and interoperable method to get electronic health record data for multiple public health and research scenarios (use cases). MedMorph has identified Cancer Reporting, Healthcare Surveys, Hepatitis C Reporting, electronic Initial Case Reporting (eICR), PCORnet, and Birth Defect Reporting use cases that support the adoption of these data elements. These specific use cases are described in more depth on their respective web pages.
Estimate the breadth of applicability of the use case(s) for this data element All 50 states participate in one or more of the public health use cases that exchange these data elements. Up to 14 territorial or city jurisdictions also participate in one of these public health use cases and use these data elements.

All hospitals and physicians who diagnose or treat cancer are required to provide cancer related laboratory information to state cancer registries.

Approximately 620,000 physicians in the US are active and have at least some component of ambulatory practice and thus are annually eligible to sampling and recruitment into the National Ambulatory Medical Care Survey (NAMCS), which samples from between 3,500 to 20,000 of these physicians annually. Presently each sampled physician submits one weeks' worth of patient encounters to NAMCS. Approximately 600 hospitals are in the National Hospital Care Survey (NHCS). 1/3 of that number are either in, or actively being recruited into, the EHR data submission mode for NHCS. NHCS is already receiving electronic CDA documents. When they reach their target of 200 hospitals submitting by this mode annually they will be receiving >1.2 million documents and sets including multiple sets of medication data annually. 

There were approximately 1,000,000 practicing physicians (as of 2020), approximately 120,000 certified physician assistants (as of 2019), and 290,000 licensed nurse practitioners (as of 2019). Most of these licensed clinicians interact with one of these public health use cases intermittently, annually. As of 2018, AHA reported 6,146 hospitals in the US experiencing 36,353,946 admissions. Almost all of those hospitals and at least half of the admissions interact with one or more of the public health use cases. The vast majority of these exchanges include full sets of medication data, including the data elements requested for USCDI consideration here.

Use Case Description A foundational goal of MedMorph is generalizability beyond the 10 use cases that are actively informing the MedMorph project, in order to support many more public health and research use cases. Therefore, other public health and research use cases that use the MedMorph architecture will also benefit from the adoption of these data elements.

Part of Core EHR Certification since at least 2014
Specified in Meaningful Use/Promoting Interoperability since Stage 1
Part of EHR Certification for Transmission to Cancer Registries (2015 and 2014 Editions)

Promoting Interoperability Programs Eligible Hospitals and Critical Access Hospitals are required to, and Merit-based Incentive Payment System (MIPS) participants may optionally, report on any two measures under the Public Health and Clinical Data Exchange objective of these programs. The § 170.315(f)(5) – Transmission to public health agencies – electronic case reporting certification criteria in the 2015 Edition Final Rule and the ONC Cures Act Final Rule, the § 170.315(f)(7) – Transmission to public health agencies – health care surveys, and the § 170.315 (f)(4) – Transmission to Cancer Registries are three such options to meet these measures.

The current standard for § 170.315(f)(5), as listed in ONC’s 2020 Interoperability Standards Advisory Reference Edition, is HL7® CDA® R2 Implementation Guide: Public Health Case Report, Release 2: the Electronic Initial Case Report (eICR), Release 1, STU Release 1.1. ONC’s Certified Health IT Product List (CHPL) lists 73 EHR or HIT Module products certified to (f)(5) using this standard. eCR IG: https://www.hl7.org/implement/standards/product_brief.cfm?product_id=436

The current standard for § 170.315(f)(7), as listed in ONC’s 2020 Interoperability Standards Advisory Reference Edition, is HL7® CDA® R2 Implementation Guide: National Health Care Surveys (NHCS), R1 DSTU Release 1.2 - US Realm. ONC’s Certified Health IT Product List (CHPL) lists 116 EHR or HIT Module products certified to (f)(5) using this standard. NHCS IG: https://www.hl7.org/implement/standards/product_brief.cfm?product_id=385

The current standard for § 170.315 (f)(4), as listed in ONC’s 2020 Interoperability Standards Advisory Reference Edition, is HL7 CDA® R2 IG: Reporting to Public Health Cancer Registries from Ambulatory Healthcare Providers, R1, DSTU Release 1.1 - US Realm. ONC’s Certified Health IT Product List (CHPL) lists 288 EHR or HIT Module products certified to (f)(4) using this standard. Cancer Reporting IG: https://www.hl7.org/implement/standards/product_brief.cfm?product_id=398

These three widely adopted CDA standards have many of the Laboratory data elements contained on this form as Shall (required) or Should (best practice to include if available) conformance criteria, which demonstrates the maturity of these commonly exchanged data elements.

CDC's comment on behalf of WA DOH

Recommend changing the element name to: 
"Laboratory test performed: date and timestamps" since timestamp is already part of the element's scope.

Submitted by Riki Merrick APHL on

The data element name and definition don’t match

The clinically relevant date time of the observation for a lab test is the specimen collection, which is part of the element definition. So if that is what is desired here it should be merged with this element Specimen collection date/time (https://www.healthit.gov/isa/taxonomy/term/3256/level-2)

If the desire is to represent the actual date/time the result was obtained as the name suggests, it should be merged with Laboratory results: date and timestamps (https://www.healthit.gov/isa/taxonomy/term/2426/level-2)

For non- lab observations the clinically relevant time is the same as this element Observation Timing (https://www.healthit.gov/isa/taxonomy/term/1411/level-2)

Unified Comment from CDC

  • Citable sources: https://www.cdc.gov/infectioncontrol/basics/transmission-based-precautions.html   CDC has promulgated use of the terms contact precautions, droplet precautions, and airborne precautions for many years.  Additional background information and useful definitions are available at: https://www.cdc.gov/infectioncontrol/pdf/guidelines/isolation-guidelines-H.pdf
     
  • Additional Use Case: HIV, STDs, Viral Hepatitis and Tuberculosis are nationally notifiable diseases for which diagnosis is dependent upon laboratory results. As such, laboratory test performed date, result value and result status are collected as part of CDC's routine surveilannce for these conditions. Additionally, beyond diagnostic tests, additional laboratory test information is collected to understand the health status of patients (e.g. HIV viral load, liver enzymes), and trends in drug susceptibility.
  • Additional Use Case: This is a standard data item used by central cancer registries in all states. Data received through data exchange from pathology laboratories to central cancer registries for CDC and NCI’s national cancer surveillance systems, as required by law.  
     
  • All of the laboratory data collected is used both for case management purposes within state, local, territorial and tribal health jurisdictions, and public health purposes at the national level. These data are integral to understanding disease transmission and to prioritize appropriate interventions for affecting communities.
     
  • Estimate number of stakeholders who capture, access, use or exchange this data element: All US States and DC are funded through CDC’s Division of HIV Prevention, Division of TB Elimination, Division of STD Prevention, and Division of Viral Hepatitis flagship Notice of Funding Actions to perform surveillance activities, including collection of these data for surveillance purposes.
     
  • Healthcare Aims: Improving patient experience of care, Improving health of populations, Reducing cost of care, provider experience of care.
     
  • Use of data element: Extensively used in production environment
     
  • CSTE supports inclusion of this measure into USCDI v3
