Mckesson's investigation determined that the root cause of the issue is a software defect.The date and time of an ecg procedure stored in mckesson cardiology ecg management is incorrectly updated when a procedure with the same accession number is received for the same patient.As designed, the second ecg procedure with the same accession number received is not imported and placed in the "failed import queue" for further review and correction by an end-user.However, no updates to the date and time of the pre-existing ecg procedure should be made in this instance.Mckesson will notify affected users of the issue and supply instructions (via safety notice) for identifying any potential affected ecg procedures.A software update to correct the problem in all affected versions of the software will be provided to affected users.
