Sustainable health financing with an ageing population: Will population ageing lead to uncontrolled health expenditure growth?
Three documents from WHO Europe are available regarding financing health for an ageing population. You can skip the third, it is about predictions for 2060. This is useless as I've said many times.
However, I agree with this comment:
These analyses find that population ageing is not, and will not become, a major driver of growth in health expenditures. Moreover, they suggest that in countries where age demographics are changing but the size of the older population is not yet large, the costs of improving coverage and access to services for older people is likely to be manageable and now is a good time to begin investing in the health system while the population is relatively young.
However, while population ageing will not become a main driver of health expenditure growth, policy choices related to how health services are delivered, the prices paid (or negotiated) for services, medicines and technologies, and volumes of care will ultimately determine health spending by age trends.
