how improvements can be made as part of ongoing
changes in ways of working and in response to issues
with performance.

Following the results of distribution fitting, the patients can be divided into different groups according to their LOS in the same unit. By analyzing each group to find out its common characteristics, ******intra-hospital transfer routes*****, admission and discharge situations, the associations among significant factors, the LOS and the treatment efficiency are evaluated.
