The Simultaneous equation method was used to allocate cost from NRPCCs to PSs. Treatment cost of 10 most common DRGs were then calculated basing on general cost data of 27,971 patients who were admitted in ordinary wards of the hospital. Results showed that in 2002 Fiscal Year ,the overall and per-unit inpatient routine service costs were 122,694,450.27 baht and 762.83 baht per patient per day respectively. The overall routine service costs was highest for internal surgical inpatient (33,780,003.35 baht) and the per-unit routine service costs was highest for ophthalmologic inpatient (1,118.11 baht per case per day). The ratio of labour cost : material cost : capital cost was 63.12 :23.99 : 12.89. Basing on the data of 160,841 in-patient days data of 430 DRGs, the average length of stay of all DRGs was 5.75 day per case.
