Under the background of new medical reform, there are many studies on the construction of internal control in public hospitals, but there is a lack of relevant studies reflecting the “verifiable” traces of internal control.According to the basic concept and scope of public hospital internal control trace, based on the characteristics of public hospital internal control trace management,it analyzes the problems in public hospitals, such as the lack of systematic internal control traces of professional committees, the limited attention to the control traces of internal control report level, and the insufficient attention to the standardization and management of in- formation control traces, which can be improved by sorting out the professional decision-making control system, the combination of business control and economic control, the optimization of information control means and other measures.
