Objective To describe the current state of hospital infection prevention and control for flexible endoscope in Shanghai, and analyze the trend of infection prevention and control quality from 2018 to 2022. Methods According to Regulation for Cleaning and Disinfection Technique of Flexible Endoscope (WS 507－2016), the quality of infection prevention and control for flexible endoscope was divided into seven parts: organizational management, layout, cleaning and disinfection (sterilization) process, environmental disinfection and sterilization, final rinse water, recording and monitoring, and occupational protection. Each quality control item was judged according to the on-site score and the correction opinion, and the item with correction opinion was judged as “unqualified”, otherwise it was “qualified”. The results of the infection prevention and control quality supervision for flexible endoscope from 2018 to 2022 were reviewed and analyzed, and the qualification rates of quality control items for hospitals at different levels and in different years were calculated. Results From 2018 to 2022, the total qualification rates of organization management, final rinse water, environmental disinfection and sterilization, and occupational protection were over 90%, and the total qualification rates of cleaning and disinfection (sterilization) process, and records and monitoring were over 80%. There was no statistically significant difference in the annual qualification rate (P>0.05). The total qualification rate of the layout was 78.19%, which was significantly higher before the outbreak of COVID-19 (2018-2019) than after the outbreak of COVID-19 (2020-2022) (P<0.001). There was no significant difference in the qualification rate of different levels of hospitals in terms of organizational management, layout, cleaning and disinfection (sterilization) process, records and monitoring, or occupational protection item (P>0.05). There were statistical differences in the qualification rates of different levels of hospitals in terms of final rinse water and environmental disinfection and sterilization (P<0.05). Conclusions The infection prevention and control qualification rate of flexible endoscope in Shanghai is high. However, the layout qualification rate after the COVID-19 pandemic is lower than before. There has been no significant trend in the quality of other items in the past five years. Weaknesses in the cleaning and disinfection (sterilization) process, as well as in recording and monitoring, are identified as key areas in management. Targeted training and supervision are recommended to address these weaknesses.
Brain-computer interfaces (BCIs) have become one of the cutting-edge technologies in the world, and have been mainly applicated in medicine. In this article, we sorted out the development history and important scenarios of BCIs in medical application, analyzed the research progress, technology development, clinical transformation and product market through qualitative and quantitative analysis, and looked forward to the future trends. The results showed that the research hotspots included the processing and interpretation of electroencephalogram (EEG) signals, the development and application of machine learning algorithms, and the detection and treatment of neurological diseases. The technological key points included hardware development such as new electrodes, software development such as algorithms for EEG signal processing, and various medical applications such as rehabilitation and training in stroke patients. Currently, several invasive and non-invasive BCIs are in research. The R&D level of BCIs in China and the United State is leading the world, and have approved a number of non-invasive BCIs. In the future, BCIs will be applied to a wider range of medical fields. Related products will develop shift from a single mode to a combined mode. EEG signal acquisition devices will be miniaturized and wireless. The information flow and interaction between brain and machine will give birth to brain-machine fusion intelligence. Last but not least, the safety and ethical issues of BCIs will be taken seriously, and the relevant regulations and standards will be further improved.
