A service engineer (se) was dispatched and unable to find any technical issues with the slide preparer. All other patient samples printed correctly. Sysmex corporation (b)(4) (s-corp) performed the investigation and determined a software program defect contributed to the event. The internal processing unit (ipu) transmits patient information to the device control manager (dcm) program. The dcm program then sends the patient information to the printer. The ipu program is allowed 25 seconds to transmit patient information to the dcm program. S-corp found the transmission of the patient information from the ipu program to the dcm program was delayed greater than 25 seconds. The dcm program did not wait for the patient information to be transmitted and erroneously instructed the printer to print the previous patient information on the slide. S-corp is developing a countermeasure to resolve the issue. The countermeasure will include reducing the delay of transmission of patient information from the ipu program to the dcm program and requiring the dcm to delete all patient information after printing. When blood smears are misidentified, there is a risk for incorrect differential result reporting. Physicians who are familiar with the patient's history and other clinical signs and symptoms request verification of results with repeat sample collection and testing for inconsistent, unexplainable results prior to making clinical decisions. Good laboratory practice and regulatory requirements, mandates a system be in place for confirming and reporting abnormal values and/or significant changes in patient test results, employing user-defined delta checks, data and printout reviews, and correlation with peripheral smears. The user appropriately verified patient information prior to result reporting.
