That’s problematic for two reasons.
Competing for the same resources
First, the two systems do not have separate pools of doctors and nurses. They compete for the same surgeons, anaesthetists and other scarce health workers. A surgeon operating in a private hospital cannot simultaneously be operating on someone waiting in the public system.
Second, a significant number of private procedures don’t benefit the patient. Things like knee arthroscopy, spinal surgery, and cardiac stents for people with stable angina are no better than a placebo. This compounds the problem because it ties up scarce resources that could be put to better use in the public system.
One Australian study looked at how a particular heart examination (coronary angiography) varies from place to place. It found a large variation in how often this invasive diagnostic procedure is done around the country, but the change was only weakly related to rates of heart disease. The strongest correlation between how often these angiograms get carried out is not how sick people are, but the rate of private-hospital cardiac admissions. In other words, more of these expensive tests get done where there is more money, or at least, more private health insurance.
More care isn’t always better care.
Yet we subsidise this arrangement heavily. The Commonwealth spends around $8 billion a year directly subsidising private health insurance. That’s roughly a third of these private insurers’ annual revenue.
Think about how odd that is.
Taxpayers (including the majority without private hospital cover) subsidise a system whose most celebrated benefit is that those with insurance can get to the front of the queue for planned care.
Meanwhile, the people relying entirely on the public system are those with less money and greater health needs.
Yet, despite the hand they have been dealt, public hospitals perform remarkably well where it matters most. They carry the overwhelming majority of emergency care and look after most Australians when they suffer serious acute illness. To see this, look at Australia’s rates of mortality following stroke and heart attack – among the best in the world.
This is thanks to the public hospital system that treats the vast majority of stroke and heart attack victims.
Our two queues
There’s nothing inherently wrong with private provision of health care. But shouldn’t we question how the system allocates scarce healthcare resources and whether ability to pay should determine how quickly someone gets treatment?
Australia likes to think of itself as having universal health care. The principle behind Medicare is that access should reflect medical need rather than the size of your wallet.
Yet for a large amount of elective hospital care we have effectively built two queues.
One moves faster if you can afford the ticket, with the taxpayer subsidising that ticket.
Perhaps that deserves just a little more attention than tweaking at the edges of the PHI rebate?
