Health expenditure I: treatment versus prevention, sustainability and equity

Four features, all stable enough to state as trends without quoting a figure.

• Health spending has grown faster than the economy for decades, so it takes a rising share of national income and of government budgets. This is true across almost every high-income country, which is a clue that the cause is general rather than an Australian policy failure.
• Government pays most of it, split between federal and state, with the remainder from individuals out of pocket and from private health insurance.
• Hospitals and primary care take the largest shares. Medicines and referred medical services follow. Public health and prevention take a small share of the total — a few cents in the dollar — and that share has not grown.
• Individuals pay a meaningful share directly, and it is concentrated in dental care, some allied health and psychology, and specialist gap fees — precisely the services that sit outside or at the edge of universal coverage.

The last two facts together are the whole problem. The services with the largest long-run health return receive the smallest share, and the costs that fall on individuals fall in the areas where cost most directly stops people getting care.

The case for prevention is not that treatment is wasteful. It is that the two buy different things, and the mix is heavily weighted toward the one with the smaller remaining gain.

• Prevention acts on many people at once. A structural measure — tobacco regulation, food policy, road design, immunisation — changes the risk of a whole population, not one patient. That is why the largest health gains in Australian history came from prevention rather than from treatment.
• Treatment acts on one person at a time, and it works. It is not the alternative to prevention; it is what you need when prevention did not happen, and it is where the moral urgency is, because the person is in front of you.
• They operate on different timescales. Treatment produces a result now. Prevention produces a result in a decade or two, in a population, measured as an absence.

So why does the balance not shift, given that everyone in health policy knows this? Five reasons, and an answer that gives the mechanism rather than just asserting “more should be spent on prevention” is the one that scores.

• Prevented illness is invisible. Nobody knows they are the person who did not have the heart attack. There is no constituency for a benefit no one can identify as theirs.
• The timescales do not match the funding cycles. Costs land in this budget, benefits in one three governments from now.
• Urgency wins. A waiting list is a visible, dated, attributable failure. A rising obesity trend is not.
• The payment model rewards activity. Much of the system is paid per service delivered, so it is paid for treating and not for illness avoided.
• Prevention's levers often sit outside health. Housing, transport, planning, education, taxation. Health budgets cannot spend there, and other portfolios are not measured on health outcomes.

Two honesty points. Prevention is not always cheaper — some programs cost more than they save, and are still worth doing because they buy healthy years. And some prevention widens inequity, because uptake is highest among the least disadvantaged; that is the argument from Lesson 5 reappearing, and it is why structural prevention, which does not depend on individual uptake, is generally the more equitable form.

“Health spending is unsustainable” is a claim, not a fact, and it is usually made without saying what would have to be true for it to be sustainable. Start with the drivers, because they determine which responses could possibly work.

• New technology and new medicines. The largest driver in most analyses. New treatments are usually additions rather than replacements: they treat people who previously could not be treated, which is a gain and a permanent new cost.
• Rising expectations and earlier diagnosis. More conditions are detected and considered treatable than a generation ago.
• Chronic disease and comorbidity. Long-duration conditions cost for decades rather than for an episode.
• Population growth and ageing. Real, and a smaller driver than most people assume — a common exam misconception. Ageing raises costs steadily and predictably; technology raises them faster.
• Prices, especially workforce. Health is labour-intensive and cannot automate away most of its labour, so its costs rise with wages generally.

What follows: because the largest driver is doing more that works, spending growth is partly a measure of success. The sustainability question is therefore not “how do we spend less?” but “how do we get more health from what we spend, and who pays for the growth?”

Four responses, with their consequences:

• Improve value. Stop paying for low-value care, invest in prevention and primary care, and reduce avoidable admissions. The best answer and the slowest.
• Raise revenue. Politically hard, and it is a distribution decision as much as a fiscal one.
• Shift cost onto individuals. Reduces government spending immediately, and converts a budget problem into an access problem — which reappears later as more expensive illness.
• Ration. Formally through what is covered, or informally through waiting lists. Informal rationing is rationing that nobody has to defend.

Every response to cost pressure moves the burden somewhere. The question is never whether someone pays; it is who, and whether they can.

The syllabus groups these three words together, and the grouping is the insight: a spending decision made for sustainability reasons lands as an access outcome and shows up later as an equity outcome.

Follow one chain.

• A government facing cost pressure reduces the subsidy for a category of care, or lets the subsidy fall behind the cost of providing it.
• Providers charge a gap. The service still exists, and its affordability gate now fails for some people.
• Those people delay or skip care. Delay is not evenly distributed — it concentrates in exactly the groups from Lesson 3.
• Conditions present later and more severely, and are treated in more expensive settings, often emergency departments.
• The saving is partly or wholly recovered as a cost elsewhere in the system, and the gap in health outcomes widens.

Dental care is the clearest Australian illustration of that chain running to completion: largely outside universal coverage, the highest reported rate of cost-related delay of any common service, a strong socioeconomic gradient in outcomes, and consequences that arrive in hospitals as preventable admissions.

Two further equity dimensions belong in a full answer:

• Vertical equity. Treating people with greater need more generously — the principle behind concession arrangements and safety nets. Equal treatment of unequal need is not equity.
• Geographic equity. Funding formulas that follow population rather than need under-fund areas with older, sicker or more dispersed populations.

The dot point asks about both, and they are affected differently — which is the structure of a strong answer.

The tension is real and it is not resolvable by spending more on everything. It is an opportunity-cost problem: money spent treating today's illness is money not spent preventing tomorrow's, and the people who would have benefited from the second option cannot lobby for it, because they do not know who they are.

Which is the honest conclusion to reach: the balance is not obviously wrong because the current population's needs are real and urgent. It is systematically biased, because only one of the two options has a constituency. Recognising a structural bias rather than a mistake is what separates a top-band answer here.

For each decision, state the opportunity cost, who benefits, and who bears the consequence.

Write two short arguments, each of about six sentences.

First: argue that a government facing cost pressure should shift spending toward prevention, and name what it must accept in doing so. Second: argue the opposite — that the current population's urgent, treatable illness has the stronger claim — and make that argument as well as you can rather than as a straw man.

Then write one sentence saying which you find more persuasive and why.
