On top of that, days later, patient safety managers across the Veterans Health Administration (VHA) were told that drug-to-drug interactions, duplicate medication orders, and allergy checks were not functioning as expected, and they too were provided with remedial actions.
Oracle applied a successful software patch on in April 2023, to ensure accurate VUIDs were attached to all mail order pharmacy–processed prescriptions from that date forward. However, the OIG learned the incorrect VUIDs sent from new EHR sites and stored in the Health Data Repository from as far back as October 2020 had not been corrected. Case told the subcommittee that on November 29, 2023, the VHA Pharmacy Council reported withdrawing a request for Oracle to send corrected medication VUID data to the Health Data Repository , on the presumption that remaining inaccurate VUIDs would expire in early April 2024, and the data would be corrected at that time.
The OIG is concerned, Case said, that patient medication data remains inaccurate almost a year after VA learned of the issue. The mail order pharmacy-related data generated from approximately 120,000 patients served by new EHR sites are still incorrect. These patients face an ongoing risk of an adverse medication-related event if they receive care and medications from a VA medical center using the legacy EHR system.
The OIG also learned of other problems associated with transmission of medication and allergy i nformation, which could have consequences such as:
- Patient medications being discontinued or stopped by new HCPs using Cerner that appear in ViSTA as active and current prescriptions;
- Allergy-warning messages not appearing when intended or inappropriately appearing for the wrong medication;
- Duplicate medication order checks not appearing when intended or inappropriately appearing for the wrong drug;
- Patient active medication lists having incomplete or inaccurate information, such as missing prescriptions, duplicate prescriptions, or incorrect medication order statuses.
The OIG warned VHA employees about the risks, although it wasn’t possible to determine who might actually be at risk. A VHA leader told the OIG that all patients who have been prescribed any medications or have medication allergies documented at a at a Cerner site are at risk. That could mean as many as 250,000 patients: As of September 2023, approximately 190,000 patients had a medication prescribed and 126,000 had an allergy documented at a new EHR site.
Case Example
Not surprisingly, “the OIG is not confident in [EHRM-Integration Office] leaders’ oversight and control of the new systems’ Health Data Repository interface programming,” Case said. He cited the case of a patient with posttraumatic stress disorder and traumatic brain injury with adrenal insufficiency. Four days prior to admission, a ViSTA site pharmacist used the EHR to perform a medication reconciliation for the patient. The data available did not include the patient’s most recent prednisone prescription, which had been ordered by an HCP at a facility using Cerner.
A nurse practitioner performed another reconciliation when the patient was admitted to the residential program, but the patient was unsure of all their medications. Because the most recent prednisone prescription was not visible in ViSTA, the prednisone appeared to have been completed at least 3 months prior to admission and was therefore not prescribed in the admission medication orders.
