"Modelling Usage and Cost of NSW Hospitals - An Overview"

Research output: Contribution to conference (non-published works)Paper


This paper provides an overview of a socioeconomic model of hospital users in New South Wales developed as part of a three year Australia Research Council grant. The model is based on four years of separations from both public and private hospitals, including New South Wales residents treated outside of the state. A unique patient ID is attached to each separation enabling related hospital separations to be attributed to the same (anonymous) patient. A unique measure of socioeconomic status is then imputed for each patient based on the empirical distribution of equivalent family income on census night of a person living in the same geographic area and of the same sex and age. Costs are also calculated for each separation enabling the total patient cost of treatment to be identified, including inter alia average costs of treatment by socioeconomic status, type of hospital or disease. Spatial analysis can be performed at levels as low as an average of 200 households. A model of private health insurance (PHI) is also created to estimate the likelihood that
a given individual will purchase PHI, and given the need to attend hospital, whether they will choose a public or private hospital. A facility is also developed that enables projected patient numbers and associated costs to be estimated.
