MRI allocation analysis of regional hospitals based on queuing simulation model / 中国医学装备

ABSTRACT

Objective:Setting up a queuing simulation model to study the allocation and usage of MRI in certain regional hospital in East China. To find out the causes and put forward suggestions. Methods: Statistical method was used for statistical analysis of MRI inspection time. Queuing simulation model was used to analyzing MRI allocation and used in 7 top hospitals. The waiting queue length, average queue length, sojourn time and waiting time was calculated.Results: The average MRI examination waiting time of the 7 top hospitals in the whole region is 0.403 h. The waiting time of 2 hospitals is more than 40 min while which is less than 20 min in 3 hospitals. The equipment utilization rate is higher in 2 hospitals (vacancy rate is 11.9%-16.4%) while which is lower in 2 other hospitals (vacancy rate is 52.3%-58.9%).Conclusion: The problem of health allocations of resources could be solved by establishing regional MRI examination center radiation regional around.
