Abstract

Our study found that the overall likelihood of utilising PHI versus utilising Medicare for in-patient hospitalisation, adjusted for all demographic characteristics, decreased between 1981 and 1998 but increased precipitously after 1999. We also found that the determinants of using PHI have changed significantly across health policy eras. The most significant changes occurred with respect to age (the probability of PHI use by older individuals increased) and socio-economic status (the probability of PHI use by average and disadvantaged individuals increased). This shift in the effects of determinants of PHI suggests that the introduction of the recent health policies were associated with a change in both the age and socio-economic profile of individuals who utilise PHI.
