Abstract: Objective To explore the influence of hospital informatization on case follow-up of radiology department.Methods The cases in 2016 and 2018, that were followed up and discussed in the department, were retrospectively analyzed. The number of cases tracked and the kind of diseases in the two periods were compared. The methods, time, frequency, interest of tracking cases in the two periods were counted by questionnaire. Results There was little difference in the number of cases between the two periods, and the kind of diseases increased. With the continuous improvement and enrichment of the functions and contents of the outpatient medical record system, the inpatient medical record system and the pathological system, real-time network query had become the main way of tracking cases. Time spent significantly decreased（P<0.05）; Physician interest and willingness increased significantly(P<0.05).Conclusions Hospital informatization greatly facilitates the case follow-up of radiology department. Under the new situation, we should pay more attention to and make good use of this tool.
