Abstract：Objective: To explore the effect of closed-loop management in the procedure of magnetic resonance imaging (MRI) examination for critically ill patients. Methods: Fifty-four critically ill patients who underwent MRI in the First Affiliated Hospital of Wenzhou Medical University from August 2020 to November 2020 after the process reformation were selected from picture archiving and communication systems (PACS) as the experimental group, and 28 critically ill patients who underwent MRI before the process reformation in June 2020 were allocated to the control group. We analyzed the time data and the problems in the MRI process of critically ill patients. Through multi-department collaboration, closed-loop management measures were applied to transform the process, a closed-loop path was formed for key stages, such as MRI appointments, waiting before examination, examination, and report sharing. The total length of MRI examination (including appointment duration, waiting duration before examinations, examination duration, and report sharing duration), the satisfaction degree of medical staff, and other indicators were compared and evaluated between the two groups. Results: Compared with the control group, the experimental group had significantly shorter appointment time, waiting time, examination time, report sharing time, and the overall MRI examination time (P<0.05). Compared with before process transformation, the satisfaction degree of doctors, nurses and patients after process transformation was improved (P<0.001). Conclusion: The application of closed-loop management could make all aspects of the examination seamless, effectively shorten the whole duration of the MRI examination for critically ill patients, improve the satisfaction degree of medical staff and patients, and guarantee the medical safety of patients.
