Abstract

Objective Many studies on the cost of Parkinson disease (PD) have been published; however, there are limited studies pertaining to this issue in Asia. This study looks to assess the direct medical costs of patients with PD at a university hospital in Japan by calculating the average monthly direct medical costs of PD patients from July to December 2008.
Methods We enrolled 724 consecutive patients (411 women and 313 men) with PD who were registered in Japan's "Specified Disease Treatment Research Program" and obtained data on the total direct medical costs of all patients.
Results Values are reported as the mean (standard deviation). The major finding of the direct medical cost analysis was that the outpatient clinic cost per subject (n=715) was USD 485.74 (376.31) per month. A multivariate analysis revealed that a younger age, the presence of wearing-off, hallucination, and longer disease duration increased the direct medical cost significantly. Disease severity had no influence on the direct medical costs. A longer disease duration was significantly correlated with higher hospitalization costs.
Conclusion The direct medical cost of PD in Japan was found to be similar to that in Western countries. Costs due to productivity loss exceeded the direct costs, and they may be reduced through the better integration of PD patients in the work environment.
