AN EVALUATION IS IN PROCESS. A FOLLOW-UP REPORT WILL BE SUBMITTED WHEN THE EVALUATION IS COMPLETE. ALL AVAILABLE PATIENT INFORMATION WAS INCLUDED. ADDITIONAL PATIENT DETAILS ARE NOT AVAILABLE.
TECHNICAL INVESTIGATION PERFORMED BY THE ABBOTT SPECIALIST REVEALED THAT THE ALINIQ AMS RELEASED A NEG (NEGATIVE) RESULT (COV15) THROUGH A CALCULATION DONE BY AN ALINIQ AMS CUSTOM RULE BASED ON AN ASSESSMENT OF THE THREE NUMERIC RESULTS FOR COV15 GENE E, COV15B ORF1 AB AND COV15C QC. FURTHER ANALYSIS SHOWED THAT THE INSTRUMENT RELEASED AN "INVALID" RESULT WHICH WAS NOT ASSOCIATED TO THE QUALITATIVE RESULT (COV15) BECAUSE IT WAS INVALID. THE INSTRUMENT SENT THE INVALID RESULT INFORMATION (¿X¿ FLAG) FOR THE QUALITATIVE RESULT THAT WAS DISCARDED. FOR THE QUANTITATIVE (NM, ¿NUMERIC¿) RESULT (COV15A GENE E, ORF AND COV15B ORF1 AB), THE INSTRUMENT REPORTED ¿F¿ (¿FINAL¿, VALID RESULT) RATHER THAN ¿X¿, NOT MARKING IT ¿INVALID¿ AND, AS SUCH, NOT TO BE DISCARDED BY THE ALINIQ AMS DRIVER. CONSEQUENTLY, THESE QUANTITATIVE TESTS WERE USED TO CALCULATE THE QUANTITATIVE RESULTS THOUGHT THE ALINIQ AMS RULE AND TO REPORT IT INTO THE COV15 TEST. UPON RECEIPT OF THE QUANTITATIVE RESULT, THE ALINIQ AMS CALCULATION RULE WAS TRIGGERED, RELEASING THE QUALITATIVE "NEG" VALUE. IT WAS THEN MANUALLY VALIDATED BY THE LAB TECHNICIAN, RELEASED TO THE LIS, AND SENT TO THE COMPETENT DEPARTMENT. TO ADDRESS THIS SCENARIO, THE ALINIQ AMS RULE WAS UPDATED TO COMPENSATE THE INCORRECT DATA INPUT RECEIVED FROM THE INSTRUMENT FOR INVALID QUANTITATIVE RESULT. AN ANALYSIS OF THE AVAILABLE ALINIQ AMS LOGS OF THE LAST 7 DAYS WAS PERFORMED AND IT DIDN¿T FIND ANY OTHER SIMILAR ISSUES. TRENDING REVIEW DETERMINED NO TREND FOR THE ISSUE FOR THE PRODUCT. DEVICE HISTORY RECORD REVIEW DID NOT SHOW ANY POTENTIAL NON-CONFORMANCES, OR DEVIATIONS. LABELING WAS REVIEWED AND FOUND TO ADEQUATELY ADDRESS THE ISSUE UNDER REVIEW. THE ALINIQ AMS SMART RULE EDITOR (SRE) USER MANUAL PROVIDES ADEQUATE LABELING REGARDING HOW A RULE SHOULD MANAGE FLAGS RECEIVED FROM THE ANALYZER FOR EACH TEST. BASED ON THE AVAILABLE INFORMATION WITHIN THE COMPLAINT, THE ALINIQ AMS WAS WORKING CORRECTLY, AND NO MIDDLEWARE MALFUNCTIONS OR DEFICIENCIES WERE IDENTIFIED. AS PER THE ANALYSIS PERFORMED, THE INCORRECT NEGATIVE COV15 TEST RESULT WAS DUE TO THE INCORRECT DATA INPUT RECEIVED BY THE MIDDLEWARE: THE NON-ABBOTT INSTRUMENT (M10) DID NOT SEND AN ¿INVALID¿ FIELD FOR THE QUANTITATIVE RESULT, BUT RATHER MARKED IT AS VALID AND TRIGGERED THE ALINIQ AMS RULE TO EVALUATE IT.
THE CUSTOMER REPORTED THAT FOR SAMPLE ID (B)(6), PROCESSED ON (B)(6) 2023, A POS (POSITIVE) COV15 (COVID) TEST RESULT WAS ERRONEOUSLY RELEASED AS NEG (NEGATIVE). THE ALINIQ AMS ANALYZER MANAGEMENT SYSTEM) RELEASED A NEG (NEGATIVE) RESULT THROUGH A CALCULATION DONE BY AN AMS RULE BASED ON AN ASSESSMENT OF THE THREE NUMERIC RESULTS FOR COV15 GENE E, COV15B ORF AB AND COV15C QC. THE FINAL RESULT FOR THE TEST WAS MANUALLY VALIDATED BY THE USER, RELEASED TO THE LIS AND SENT TO THE COMPETENT DEPARTMENT. AS AGREED, THE AMS RULE, IMPLEMENTED DURING THE INSTALLATION ACTIVITY AT THE CUSTOMER'S PREMISES, ONLY EVALUATED THE QUANTITATIVE RESULTS RECEIVED BY THE INSTRUMENT, NOT CONSIDERING QUALITATIVE AND INVALID ONES. IN THIS SPECIFIC CASE, THE SAMPLE REPORTED, GENE E, IS THE NUMERIC RESULT OF THE COV15A GENE E TEST (0.00), ORF IS THE NUMERIC RESULT OF THE COV15B ORF AB TEST (0.00) WHILE QC IS THE NUMERIC RESULT OF THE COV15C QC TEST (33.82). THE RULE WAS TRIGGERED, RELEASING THE QUALITATIVE RESULT (NEG). THE AMS RELEASED AN "INVALID" RESULT SIGNALED VIA THE "X" FIELD IN THE DRIVER AND RELATED TO THE QUALITATIVE RESULT. THE "INVALID" INFORMATION WAS NOT SENT BY THE INSTRUMENT ON THE QUANTITATIVE RESULT, CONSIDERING IT A VALID RESULT. UPON RECEIPT OF THIS VALID AND QUANTITATIVE RESULT, THE AMS RULE WAS TRIGGERED, RELEASING THE "NEG" VALUE. THE CUSTOMER REPORTED THAT THE PATIENT UNDERWENT A BRONCHOSCOPY THAT WAS SCHEDULED BY THE PULMONOLOGY DEPARTMENT. HOSPITAL PRACTICE WAS TO WAIT (EXCEPT IN EMERGENCIES) FOR THE PATIENT TO BE NEGATIVE BEFORE RUNNING THIS TEST. NO NEGATIVE PATIENT IMPACT WAS REPORTED AS A RESULT OF PERFORMING THE SCHEDULED TREATMENT BASED ON THE ERRONEOUS NEGATIVE RESULT WHEN THE PATIENT WAS ACTUALLY POSITIVE. THE INSTRUMENT INTERFACING WAS PERFORMED IN (B)(6) 2022. AN ANALYSIS OF THE AVAILABLE LOGS OF THE LAST 7 DAYS DIDN¿T FIND ANY OTHER PROBLEMS, BUT THERE WAS NO WAY TO CONFIRM THE TOTAL NUMBER OF PATIENTS IMPACTED STARTING FROM THE CONFIGURATION OF THE AMS IN (B)(6) 2022 DUE TO A LACK OF AVAILABLE DATA.
