    OLYMPUS MEDICAL SYSTEMS CORP. (OMSC) RECEIVED A LITERATURE TITLED "EFFECT OF AN AUTOMATED FLEXIBLE ENDOSCOPE CHANNELS BRUSHING SYSTEM ON IMPROVING REPROCESSING QUALITY: A RANDOMIZED CONTROLLED STUDY". BACKGROUND AND STUDY AIMS QUALIFIED REPROCESSING, OF WHICH METICULOUS CHANNELS BRUSHING IS THE MOST CRUCIAL STEP, IS ESSENTIAL FOR PREVENTION AND CONTROL OF ENDOSCOPY-ASSOCIATED INFECTIONS. HOWEVER, CHANNELS BRUSHING IS OFTEN OMITTED IN PRACTICE. THIS STUDY AIMED TO EVALUATE THE EFFECT OF AN AUTOMATED FLEXIBLE ENDOSCOPE CHANNELS BRUSHING SYSTEM (AECBS) ON IMPROVING THE QUALITY OF ENDOSCOPE REPROCESSING. METHODS THIS PROSPECTIVE, RANDOMIZED CONTROLLED STUDY WAS CONDUCTED, BETWEEN (B)(6) 2021 AND (B)(6) 2022, AT RENMIN HOSPITAL OF WUHAN UNIVERSITY, CHINA. ELIGIBLE ENDOSCOPES WERE RANDOMLY ALLOCATED TO THE AUTO GROUP (CHANNELS BRUSHED BY AECBS) OR THE MANUAL GROUP (CHANNELS BRUSHED MANUALLY), WITH SAMPLING AND CULTURING AFTER HIGH-LEVEL DISINFECTION AND DRYING. THE PRIMARY ENDPOINT WAS THE PROPORTION OF POSITIVE CULTURES FOR ENDOSCOPES. RESULTS 204 ENDOSCOPES IN THE AUTO GROUP AND 205 IN THE MANUAL GROUP WERE EVENTUALLY ANALYZED. THE PROPORTION OF POSITIVE CULTURES WAS SIGNIFICANTLY LOWER IN THE AUTO GROUP (15.2% [95% CI 10.7-21.0%])) THAN IN THE MANUAL GROUP (23.4% [95% CI 17.9-29.9%]). CONCLUSIONS AECBS COULD EFFECTIVELY REDUCE BIOBURDEN AND IMPROVE REPROCESSING QUALITY OF GASTROSCOPES AND COLONOSCOPES. IT HAS GREAT POTENTIAL TO REPLACE MANUAL BRUSHING AND LOWER THE RISK OF ENDOSCOPY-ASSOCIATED INFECTIONS, PROVIDING A NEW IDEA FOR THE OPTIMIZATION OF REPROCESSING. POSITIVE IN CULTURE TEST - 79 OF THE 79 POSITIVE IN CULTURE TESTS, 34 OLYMPUS SCOPES WERE REPORTED TO OLYMPUS. THIS LITERATURE ARTICLE REQUIRES 34 REPORTS. THE RELATED PATIENT IDENTIFIERS ARE AS FOLLOWS: (B)(6) GIF-XQ260/2035124 (B)(6) CF-Q260AI/2914692 (B)(6) GIF-Q260 /2251882 (B)(6) GIF-Q260 /2251880 (B)(6) GIF-XQ260/2522612 (B)(6) GIF-XQ260/2522683 (B)(6) GIF-XQ260/2135577 (B)(6) CF-Q260AI/2316718 (B)(6) GIF-HQ290/2512845 (B)(6) GIF-XQ260/2345963 (B)(6) GIF-H290/2523634 (B)(6) GIF-HQ290/2513476 (B)(6) CF-H290I/ 2500920 (B)(6) CF-H290I/2500915 (B)(6) GIF-H260/2557771 (B)(6) GIF-HQ290/2857287 (B)(6) GIF-HQ290/2857264 (B)(6) CF-HQ290I/2854046 (B)(6) CF-HQ290I/2854035 (B)(6) GIF-HQ290/2858329 (B)(6) CF-HQ290I/2854501 (B)(6) GIF-HQ290/2746295 (B)(6) GIF TYPE H260/2768996 (B)(6) CF-HQ290I/2743299 (B)(6) GIF TYPE H260/2769049 (B)(6) GIF TYPE H260/2769054 (B)(6) GIF-HQ290/2960370 (B)(6) GIF-HQ290/2960372 (B)(6) GIF-HQ290/2960314 (B)(6) GIF-HQ290/2960278 (B)(6) CF-HQ290I/2955422 (B)(6) CF-HQ290I/2955421 (B)(6) CF-HQ290I/2955424 (B)(6) CF-HQ290I/2955411 THIS MEDWATCH REPORT IS FOR PATIENT IDENTIFIER (B)(6).
