HRSA 2023 Uniform Data System (UDS) Patient Level Submission (PLS) (UDS+) FHIR IG
1.0.1 - STU1 Release 1 - Standard for Trial-Use International flag

This page is part of the HRSA Uniform Data System (UDS) Patient Level Submission (PLS) (UDS+ or uds-plus) FHIR IG (v1.0.1: STU1) based on FHIR (HL7® FHIR® Standard) R4. This is the current published version in its permanent home (it will always be available at this URL). For a full list of available versions, see the Directory of published versions

Resource Profile: De-Identified UDS Plus Lab Observation

Official URL: http://fhir.org/guides/hrsa/uds-plus/StructureDefinition/uds-plus-lab-observation Version: 1.0.1
Standards status: Trial-use Maturity Level: 2 Computable Name: UDSPlusLabObservation

The UDS+ profile is based on the Observation resource and establishes the core elements, extensions, vocabularies and value sets for representing lab observations for UDS+ program.

Introduction

This profile is used to represent de-identified Observation for Lab Result information. The de-identification process has to remove all data elements not explicitly identified as “SUPPORTED” in the profile.

The HHS De-identification Guidance is to be followed to ensure appropriate level of de-identification is performed.

According to the HHS guidance, dates should not have a precision of more than the year. This means month and day cannot be included. This includes Observation for Lab Result.period.

In FHIR Resources, text elements and reference.display elements which provide human readable information to the providers may be generated using programs and tools from the data present within the resource. For e.g a Observation for Lab Result resource text element may contain information such as the Observation for Lab Result date, patient information. This type of information will enable identification of the individuals. In order to avoid inadvertent revealing of PII/PHI, text elements cannot be included in the De-identified FHIR resource and the submission will be rejected when text elements are present by the validation process.

Ids and References

The original Observation for Lab Result resource id should not be included in the De-identified Observation for Lab Result instance. Instead a new id should be created and provided as part of the FHIR resource. The Data Submitter should be capable of using the generated id to relink the data to the original Observation for Lab Result. All resource references to the Observation for Lab Result submitted as part of the UDS+ report should refer to newly generated id.

Resource references cannot contain text element as it may contain PHI/PII. The text element for following references are not allowed

  • subject
  • encounter

Date Truncation

The Data Submitter has to truncate the following dates to only have a precision of year

  • effective[x]
