    ON (B)(4) 2019: DFB NOTIFIED OF 4 PATIENTS ((B)(6) FROM MDR 3003690398-2019-00001, (B)(6) FROM MDR 3003690398-2019-00002, (B)(6) FROM MDR 3003690398-2019-00003, AND (B)(6) FROM MDR 3003690398-2019-00004) WHO HAD BEEN HOSPITALIZED OR HAD THEIR HOSPITALIZATION PROLONGED AFTER TESTING POSITIVE FOR ACHROMOBACTER XYLO/DENITRIFICANS AFTER UNDERGOING A BRONCHOSCOPY. SCOPE(S) REPROCESSED IN OER-PRO USING ALDAHOL 1.8 HIGH LEVEL DISINFECTANT (ALDAHOL) AS THE DISINFECTING AGENT. ON (B)(6) 2019: DFB CONFIRMED WITH THE HOSPITAL THAT THE ALDAHOL WAS USED IN MANNER CONSISTENT WITH INSTRUCTIONS FOR USE (I.E. ALDAHOL IS TESTED PRIOR TO EACH CYCLE USING RECOMMENDED TEST STRIPS AND THAT MAXIMUM REUSE PERIOD FOR THE ALDAHOL IS 14 DAYS). ON (B)(6) 2019: HOSPITAL PROVIDED RELEVANT ALDAHOL LOT NUMBERS AND ASSOCIATED CHANGE DATES: (B)(6) LOT #191913. (B)(6) LOT #191947. (B)(6) LOT #191947. (B)(6) LOT #191947. HOSPITAL REPORTED THAT THEY WERE CONDUCTING MICROBIAL TESTING ON THE OER-PRO, VIDEOSCOPES, ADAPTOR, COMPRESSOR, WATER SUPPLY AND DRAINS (AIR EXCHANGES ARE CHECKED ON A REGULAR BASIS AND ROOM MAINTAINS NEGATIVE PRESSURE). HOSPITAL CONFIRMED ALL FOUR PATIENTS WERE IMMUNOCOMPROMISED PRIOR TO THE BRONCHOSCOPY. ON (B)(6) 2019: DFB REQUESTED (B)(4) LABORATORY TO CONDUCT MICROBIOLOGICAL TESTING ON RETAINED SAMPLES OF ALDAHOL LOT NUMBER 191947 (ALL FOUR PATIENTS HAD A MINIMUM OF ONE BRONCHOSCOPE WITH THIS LOT) AGAINST A. XYLO/DENITRIFICANS. (B)(6) 2019: INITIAL REPORTER PROVIDED A PRELIMINARY INVESTIGATION SUMMARY OF THE MICROBIAL TESTING ON THE OER-PRO, VIDEOSCOPES, ADAPTOR, COMPRESSOR, WATER SUPPLY AND DRAINS WHICH CONCLUDED, "ACHROMOBACTER WAS NOT ISOLATED FROM ANY CULTURE OF THE MOST LIKELY RESERVOIRS. RESULTS DO NOT EXCLUDE THE POSSIBILITY OF A RESERVOIR OF THE ORGANISM BEING PRESENT IN THE BRONCH LAB." THIS SUMMARY ALSO REPORTED THAT THE SUSCEPTIBILITY PROFILE OF PATIENT (B)(6) (SEE MDR 3003690398-2019-00002) ISOLATE WAS RESISTANT TO ALL DRUG CLASSES TESTED WHEREAS THE ISOLATES FROM THE OTHER THREE PATIENTS ((B)(6) FROM MDR 3003690398-2019-00001, (B)(6) FROM MDR 3003690398-2019-00003, AND (B)(6) FROM MDR 3003690398-2019-00004) WERE SIMILAR TO EACH OTHER IN SHOWING SUSCEPTIBILITY TO PIP/TAZO, MEROPENEM, LEVOFLOXACIN, AND TRIM/SULFA. SHE ALSO PROVIDED A PATIENT INFORMATION TABLE WHICH INCLUDED PRE-EXISTING CONDITIONS. 28 AUG 2019: DFB MEDICAL AFFAIRS REVIEWER EVALUATED THE FOUR CASES WITH ACCOMPANYING DOCUMENTATION AND DETERMINED THAT THE FDA WAS TO BE NOTIFIED IN THE FORM OF INITIAL 30-DAY REPORTS PENDING THE RESULTS FROM (B)(4) LABORATORY. 19 SEP 2019: DFB RECEIVED (B)(4) LABORATORY STUDY REPORT (STUDY IDENTIFICATION NUMBER (B)(4)) "ANTIBACTERIAL ACTIVITY AND EFFICACY OF (B)(4), LLC'S TEST SUBSTANCE USING A TIME-KILL PROCEDURE" WHEREIN ALDAHOL LOT # 191947, EXPIRY 01 JAN 2020 AND ACTIVATOR LOT # 271922, EXPIRY 01 AUG 2020, (THE SAME LOT COMBINATIONS USED IN A MINIMUM OF ONE BRONCHOSCOPY FOR EACH PATIENT) WERE INOCULATED WITH M. TERRAE AND A. XYLOSOXIDANS, THEN MIXED AND INCUBATED. REDUCTION OF MICROORGANISMS WERE CALCULATED BY COMPARING INITIAL MICROBIAL CONCENTRATIONS TO FINAL MICROBIAL CONCENTRATIONS. STUDY RESULTS INDICATE THAT FOR M. TERRAE, WHICH WAS USED AS A COMPARISON BECAUSE THIS TEST ORGANISM WAS STUDIED IN THE ORIGINAL 510(K) TO DETERMINE DISINFECTION EFFICIENCY, THE ORGANISM DROPPED BELOW THE LIMITS OF DETECTION IN ALL THREE REPLICATES AFTER TWO MINUTES. THE A. XYLOSOXIDANS WAS DRASTICALLY REDUCED AFTER TWO MINUTES, BELOW THE LIMITS OF DETECTION IN ONE REPLICATE, AND BELOW THE LIMITS OF DETECTION IN ALL THREE REPLICATES AFTER TEN MINUTES. ACCORDING TO THE INDICATIONS FOR USE, THE EXPOSURE FOR HIGH-LEVEL DISINFECTION IS 10 MINUTES AT 20°C. BASED ON THESE RESULTS, IT IS CONCLUDED THAT THIS LOT OF ALDAHOL FUNCTIONED AS EXPECTED AND WAS NOT A CONTRIBUTING FACTOR IN THE POSITIVE TEST RESULTS OF A. XYLOSOXIDANS FOR THESE PATIENTS.

    Description of Event or Problem · 1

    PATIENT ADMITTED AFTER TESTING POSITIVE FOR ACHROMOBACTER XYL DENITRIFICANS FOLLOWING BRONCHOSCOPY. BRONCHOSCOPE HAD BEEN REPROCESSED IN OER-PRO USING ALDAHOL. FACILITY REPORTED THAT A TOTAL OF 70 BRONCHOSCOPIES HAD BEEN PERFORMED IN THE MONTH OF JULY WITH 4 PATIENTS SUBSEQUENTLY TESTING POSITIVE FOR ACHROMOBACTER XYL DENITRIFICANS. HOSPITAL MICROBIOLOGY LAB EVALUATION REPORTED THAT THE ISOLATES FROM THREE PATIENTS WERE SIMILAR TO EACH OTHER SHOWING SUSCEPTIBILITY TO PIP/TAZO, MEROPENEM, LEVOFLOXACIN, AND TRIM/SULFA. THE ISOLATE FROM THE FOURTH PATIENT (THIS PATIENT DESIGNATED HERE AS PT2-W) DIFFERED FROM THE OTHER ISOLATES. CULTURE SAMPLES IN THE BRONCH LAB WERE OBTAINED TO DETERMINE COMMON SOURCE WITH SAMPLES FROM SCOPES' "BRUSH SCRUB AND FLUSH 20ML PBS" STILL PENDING RESULTS AND ALL OTHER CULTURES NEGATIVE FOR ACHROMOBACTER. PT2-W HAD FIRST BRONCH ON (B)(6) 2019 THAT RESULTED IN ADMISSION FOLLOWED BY A REPEAT BRONCH (B)(6) 2019 THEN DISCHARGE. OUTPATIENT BRONCH ON (B)(6) 2019 TREATMENT ATTEMPTED AS OUTPATIENT BUT REQUIRED ADMISSION ON (B)(6) 2019 DUE TO INABILITY TO IMPROVE. AGAIN, ALL SPECIMENS RESULTED POSITIVE FOR ACHROMOBACTER. PREEXISTING CONDITIONS: COPD, SMOKER, LUNG CA, OSA, GERD, PE, R LOBECTOMY PROCEDURE: BRONCHOSCOPY (B)(6) 2019, (B)(6) 2019, (B)(6) 2019 (OUTPATIENT). STATUS: OUTPATIENT, ADMITTED ON (B)(6) 2019 DUE TO INABILITY TO IMPROVE. INITIAL REPORTER FURTHER CLARIFIED THAT ALL FOUR PATIENTS WERE IMMUNOCOMPROMISED PRIOR TO PROCEDURES. ALL PATIENTS SUBSEQUENTLY TREATED AND RELEASED AFTER HAVING EITHER BEEN HOSPITALIZED OR HAVING HOSPITALIZATION EXTENDED DUE TO TESTING POSITIVE.
