The impacts of changes to private health insurance
(PHI) policies introduced since 1999 ? in particular
the 30% PHI rebate and the Lifetime Health Cover
? have been much debated. We present historical
analyses of the impacts in terms of the proportion of
Australians having hospital insurance cover under
different PHI policies, by age, gender and socioeconomic
status, and project these to 2010 using a new
Private Health Insurance coverage model.
The combined effect of the 30% rebate and Lifetime
Health Cover was to increase PHI membership from
just over 30% in 1998 to just under 50% by the end
of 2000, due mainly to more people taking out PHI
cover from among the richest 20% of the population.
Among the poorest 40% the impact was minimal.
Model projections suggested that, had the new PHI
policies not been introduced, then the proportion of
Australians with PHI would have declined to around
20% by 2010, compared with 40% if the current
arrangements remained in place. Also, analysis of
2001 survey data regarding choices to use a public
or a private hospital indicated that higher income
groups with or without PHI were the more likely to
have used a private hospital than lower income
groups. Among those with PHI, older people were
more likely to have used a private hospital than
younger ones.
