It was found that the management was weak. The administrative top-down MDT management mode intervention was added from 2021，and use PDCA tools to continuously improve and analyze related intervention effects. Results：The incidence of unplanned return to the operating room for reoperation in 2021 was 0.26%，lower from 0.32% in 2018-2020.Medical disputes and related quality indicators caused by unplanned return to the operating room for reoperation were significantly improved.
