(At present, the informatization construction of hospitals in my country has achieved obvious results. HIS (hospital information system) has been widely used to realize various businesses including outpatient registration, price charging, drug store management, hospitalization management, operating room management, economic calculation management, etc. It brings convenience to the management of the hospital, and greatly shortens the time for patients to seek medical treatment. But at the same time, the problems caused by the poor management of the hospital network are endless, which is completely different from the original intention of the hospital's network construction.)
