Objective To improve the operation efficiency of Magnetic Resonance Imaging(MRI)examination in hospital,solve the problem of backlog of patients in MRI examination,and ensure the smooth operation of the hospital as a whole.Methods Based on the concept of lean management,an integrated application scheme of"Identification-Analysis-Solution"(IAS)was proposed and put into practice.Results Through the implementation of the scheme,the average examination cycle of MRI in hospital patients was shortened by 55.02%,the average waiting time of patients on the day of inspection was reduced by 10.28%,and the average number of examinations per MRI device was increased by 4.34%.The patient waiting satisfaction rate increased by 9.87 percentage points.Conclusion The IAS lean tool in-tegrated application scheme can improve the operation efficiency of hospital MRI examination,and is a powerful tool to improve medical quality,safety and efficiency.
