March 1, 2022 – Advisory: MPI Demographics May Contain Unconsented Data
InterSystems has corrected a defect affecting Patient Privacy wherein consent is not applied in the determination of the “best” record. As a result, unconsented demographic data associated with the best record are displayed at the MPI-level in Patient Search and FHIR requests. This may inadvertently reveal sensitive information, such as the patient's address associated with the unconsented facility.
This issue affects all HealthShare Information Exchange and Unified Care Record versions up to and including HealthShare 2020.2.
When populating the properties in an aggregate Patient streamlet, data from the “best record” is favored. The best record is that which was last updated at the best (lowest) tier facility. The demographics associated with this record are displayed at the MPI-level in Patient Search and FHIR requests.
The correction for this defect is identified as HSIEC-3978. It is available via ad hoc change file or full kit distribution from the Worldwide Response Center (WRC). The correction ensures that consent is evaluated for each patient record prior to the determination of the best record. As a result, the MPI demographics will only contain consented data. InterSystems recommends that all affected customers apply this correction. The correction is included in Unified Care Record 2021.1, 2021.2 and in all future product releases.
