Additional Manufacturer Narrative
Context: a customer in france notified biomérieux of obtaining a false-positive instrument results on the bact/alert 3d instrument- reference 200291 (serial number: (b)(6)) when testing an advanced therapy medicinal product (atmp).Investigation results: complaint analysis: search has been performed for complaint registered for false positive results.The review did not indicate any systematic quality issue for bact/alert virtuo.No corrective or preventive actions were opened for this performance issue during the analyzed period.Review of the bact/alert® 3d: the review of the bact/alert® 3d indicates that the user mixed up the bottle id and the accession number.Steps to reproduce the customer issue has been identified during the investigation: the user scanned the accession number into the bottle id field.The instrument advanced to the accession number field but continuously beeped to alert the user that it does not recognize the bottle id / type.Then, the user scanned the bottle id number in the accession number field.The instrument reverted back to the bottle id field and continued to beep to alert the user of an issue.The user proceeded with loading the bottle into cell 1a22 while the instrument continued to alert the user with beeps.As a consequence, the instrument assigned the bottle as a generic bottle and the instrument analyzed the bottle with the wrong algorithm (#9).Indeed, the appropriate algorithm has a different initial value threshold.This use error has caused the instrument to flag the bottle as positive.When the correct bottle type is selected during the loading bottle process, the instrument analyzes the bottle with the appropriate algorithm (#25) and the bottle does not flag positive.The bottle history shows that when the correct bottle id is selected, the instrument assigned the correct algorithm and tested the bottle correctly.The bottle result was negative.The instrument is functioning as designed by flagging the bottle positive due to the use error.Instruction for use - review: the user manual provides the following instructions to the user to follow when loading bottles.Bact/alert 3d b.50 user manual 514818-1en1 reviewed; verify that the bottle id field appears white.Then scan or manually enter the bottle id.If the field is left blank when a bottle is loaded, then the bottle is considered anonymously loaded.Verify that the correct bottle type is displayed on the bottle type scroll button.If the bottle id field contains data from a generic label, the bottle type can be manually entered using the bottle type scroll button before inserting the bottle to ensure proper testing of the bottle.The instrument will also beep continuously to alert the operator that the bottle type needs to be manually entered.The audible alert can be disabled by calling biomérieux for assistance.User manual also alert the user with a warning message of improper loading.Conclusion: the false positive results has been caused by an use error related to the incorrect bottle identification.The issue has been reproduced and the investigation has confirmed that the instrument functions as intended and that the instruction for use mention the steps to correctly identify a bottle.
Additional Manufacturer Narrative
The mdr guidance, "medical device reporting for manufacturers, issued november 8, 2016", section 2.15, establishes that once a malfunction has caused or contributed to a death or serious injury, a presumption that the malfunction is likely to cause or contribute to a death or serious injury has been established.Biomérieux has performed a review and analysis of the mdr submissions, specific to the biomérieux bact/alert® reagents and virtuo® instrument.The review included mdrs submitted to the fda from 01-jan-2022 to 22-feb-2024.Based upon our review and analysis of biomérieux bact/alert® reagents and virtuo® instrument mdr submissions, there have been no customer claims of death or serious injury in the past two (2) years.Each has been investigated or is currently undergoing investigation, and any issues have been addressed by the manufacturing site.With the completion of our mdr data analysis, we have updated our mdr criteria for bact/alert® reagents and virtuo® instrument.Malfunction events for medical device problem code: a090804, false positive result will no longer be reported for all bact/alert® reagents and virtuo® instrument (product codes: mdb, mzc) as these events are not "likely to cause or contribute to a death or serious injury" if they were to recur.Moving forward, if we become aware of a death or serious injury event related to nonstandard device results obtained with an bact/alert® reagents or virtuo® instrument, we will report that event to the fda per the fda mdr guidance and update our mdr criteria to include reporting the specific associated malfunction as required by the mdr guidance.
