This study was conducted to investigate the predictors of hospital bankruptcy in Korea and to examine the predictive power for 3 types of statistical models of hospital bankruptcy. Data on 17 financial and 4 non-financial indicators of 30 bankrupt and 30 profitable hospitals in 1, 2, and 3 years before bankruptcy were obtained from the hospital performance databank of Korea Institute of Health Services Management. Significant variables were identified through mean comparison of each indicator between bankrupt and profitable hospitals, and the predictive power of statistical models of hospital bankruptcy were compared.
The major findings are as follows.
1. Nine out of 21 indicators - fixed ratio, quick ratio, operating profit to total assets, operating profit to gross revenue, normal profit to total assets, normal profit to gross revenue, net profit to gross revenue, inventories turnrounds, and added value per adjusted patient - were found to be significantly predictitive variables in Logit and Probit models.
2. The predicdtive power of discriminant model of hospital bankruptcy in 1, 2, and 3 years before bankruptcy were 85.4, 79.0, and 83.8% respectively.
With regard to the predictive power of the Logit model of hospitalbankruptcy, they were 82.3, 75.8, and 80.6% respectively, and of the Probit model, 87.1, 80.6, and 88.7% respectively.
3. The predictive power of the Probit model of hospital bankruptcy is better than the other two predictive models.
