OBJECTIVE To survey the utilization and management status of automated endoscope reprocessor (AER) in medical institutions in Jiangsu Province, providing references for improving endoscope reprocessing quality.

METHODS From Jun. 30, 2025 to Jul. 7, 2025, a questionnaire survey was conducted among endoscopy center staff and hospital-associated infection management personnel from 73 medical institutions in Jiangsu Province (including 41 tertiary hospitals, 16 primary and 16 secondary hospitals). The survey covered aspects such as configuration, functionality, usage, monitoring and maintenance for AER.

RESULTS The AER allocation rate reached 100.00%, but 79.45% of institutions had fewer than 5 units. Domestic brands dominated (60.27%), with "immersion + flow-through" and "immersion + spray + flow-through" as the primary disinfection methods (each accounting for 36.99%). Peracetic acid (78.08%) and ortho-phthalaldehyde (60.27%) were the most common disinfectants, and 84.93% of institutions used disinfectants repeatedly. Leak testing capability was available in 60.27% of AERs, while 72.60% of AERs had connection error alarm function. Although 97.26% of institutions have established new staff training systems, only 49.32% AER received regular maintenance from manufacturer.

CONCLUSIONS While AER allocation rate in Jiangsu medical institutions is high, deficiencies of AER persist in functional completeness, standardized management and systematic maintenance.
