First, it is a non-parametric method and can be used only as an exploratory method. Second, we assume the workload on the medical and health workers per hospitalized day for any patient is the same, which is unlikely to be true. It is has been reported that the implementation of day surgery arrangements-as opposed to admitting the patient a day earlier-has indeed caused excessive workload for medical and healthcare workers. A simple count of the number of hospitalized days might not properly reflect the additional work arising from the reduction of the mean duration of hospital stays. The change of the case mix of has not been incorporated in examining the change in hospitalization days, however, there is no significant change in morbidity and mortality pattern in Hong Kong during the period and the effect on the results is expected to be limited. Nevertheless, the complicated nature of the relationship between length codes. However, there is quite a substantial proportion of missing information on the disease code in the data, no result was available.
