Abstract

Objectives The aim of this study is to determine the factors that influence stroke hospitalization costs for financially high-risk groups under the DRG payment method.

Methods A retrospective study was conducted with stroke inpatients at Phramongkutklao Hospital. Data was collected from an administrative database and electronic medical records. Multiple regression analysis was performed to determine the association between hospital costs and factors that influence those costs in terms of a correlation coefficient for a financially high-risk group.

Results The results indicate that among 272 stroke patients, 57.0% were male with a mean age of 69.2 ± 14.2 years. The median charge per admission was 52,854 (IQR : 25,434, 147,229) THB and median charge per length of stay (LOS) was 5,065 (IQR : 3,347, 7,738) THB. Multiple regression analysis among 13 factors found that having surgery, use of a ventilator, prolonged LOS, and insurance type had significant correlations with stroke hospital costs (R-square = 0.83, p < 0.05).

Conclusions In conclusion, surgery, use of a ventilator, and LOS, insurance type are clinical factors that are associated with significant increased costs for financially high-risk groups.
