New Casemix Classification as an Alternative Method for Budget Allocation in Thai Oral Healthcare Service : A Pilot Study

Abstract EN

This study aimed to develop a new casemix classification system as an alternative method for the budget allocation of oral healthcare service (OHCS).

Initially, the International Statistical of Diseases and Related Health Problem, 10th revision, Thai Modification (ICD-10-TM) related to OHCS was used for developing the software “Grouper”.

This model was designed to allow the translation of dental procedures into eight-digit codes.

Multiple regression analysis was used to analyze the relationship between the factors used for developing the model and the resource consumption.

Furthermore, the coefficient of variance, reduction in variance, and relative weight (RW) were applied to test the validity.

The results demonstrated that 1,624 OHCS classifications, according to the diagnoses and the procedures performed, showed high homogeneity within groups and heterogeneity between groups.

Moreover, the RW of the OHCS could be used to predict and control the production costs.

In conclusion, this new OHCS casemix classification has a potential use in a global decision making.
