Upon investigation with the facility, it was determined that the site has a workflow intended to hold the first and second results of the hemoglobin a1c (hba1c).Based on the delta check, if the values are within 5%, the lowest value is released.If the values are not, both results are held for review.In this issue, the first two hemoglobin a1c (hgba1c) results were held based on rule (user facility programmed logic) configuration.When the third hgba1c result was processed, it was comparing to a result from january, which was not expected.During a review of the rule for the delta checks, it was determined that the "previous results" value rather than the "previous run" value was being used which caused the comparison to refer to an incorrect previous result.This is not a malfunction of the instrument manager medical device.This incident is due to an incorrect value being configured in the rule.The site implemented a workaround to manually check every result and subsequently terminated all testing on the analyzer.A patient impact statement has not yet been received from the site by data innovations and therefore patient impact has been unable to be determined.An investigation to determine patient impact is ongoing at the time of this report.

Additional information: a representative from the facility provided additional information on the potential patient impact.The facility stated that there was no patient harm as a result of the use of an unexpected previous glycohemoglobin (hba1c) result.Based on the additional patient impact information provided by the facility, two data values have been updated in section h6.First, the health effect - clinical code has been updated to 4582: no clinical signs, symptoms, or conditions.Second, the health effect - impact code has been updated to 2199 - no health consequences or impact.Information from original report: upon investigation with the facility, it was determined that the site has a workflow intended to hold the first and second results of the hemoglobin a1c (hba1c).Based on the delta check, if the values are within 5%, the lowest value is released.If the values are not, both results are held for review.In this issue, the first two hemoglobin a1c (hgba1c) results were held based on rule (user facility programmed logic) configuration.When the third hgba1c result was processed, it was comparing to a result from january, which was not expected.During a review of the rule for the delta checks, it was determined that the "previous results" value rather than the "previous run" value was being used which caused the comparison to refer to an incorrect previous result.This is not a malfunction of the instrument manager medical device.This incident is due to an incorrect value being configured in the rule.The site implemented a workaround to manually check every result and subsequently terminated all testing on the analyzer.A patient impact statement has not yet been received from the site by data innovations and therefore patient impact has been unable to be determined.An investigation to determine patient impact is ongoing at the time of this report.
