APPLICATION OF STRUCTURAL ECONOMETRICS MODEL IN THE HEALTH CARE SYSTEM TO DESCRIBE RELATIONSHIPS AMONG VARIABLES IN THE SYSTEM (THE CASE OF IRAN)

In this paper we applied structural econometrics model in to the health care system to show the interdependence between variables and to describe the relationships among them. We used the two-stage least squares (2sls) method to estimate the model parameters and the result showed three main situations. First we found that the number of the registered patients have a positive relation on the mean duration of stay in hospital, the rate of the using of beds and the mean duration of empty beds whereas it shows negative relation on total of patient days. Secondly it shows that the rate of the using of beds is positively related with the mean of occupied beds per day and the mean duration of the empty beds whereas it is negatively related with total of patient days. Finally, we also find that the rate of the using of beds is positively related with the mean of occupied beds per day and the mean duration of empty beds whereas it is negatively related with total of patient days. The findings play as a beginning and a guide line to us to study more about health care system in Iran as health care system come under increasing pressure to provide faire and equitable care to all patients.
