Health Spending in Most OECD Countries Rises, with the U.S. far Outstripping all Others


03/06/2004 - Spending on health and healthcare in most OECD countries has risen dramatically over the past five years. Combined with lower economic growth, the increase in health spending has driven the share of health expenditure as a percentage of GDP up from an average 7.8% in 1997 to 8.5% in 2002. This is in sharp contrast to the period 1992 – 1997, when the share of GDP spent on health remained almost unchanged. 

OECD Health Data 2004, the most comprehensive source of comparable statistics on health and health systems across the 30 member countries of the OECD, shows that U.S. health expenditure grew 2.3 times faster than GDP, rising from to 13% in 1997 to 14.6% in 2002. Across other OECD countries, health expenditure outpaced economic growth by 1.7 times. In the United  States, health spending reached  $5267 per capita in 2002, almost 140% above the OECD average of $2144 and around 10 times as more than Mexico and Turkey,  which spent $553 and $446 respectively.
This growth in health expenditure was, in part, a deliberate policy in some countries, such as the United Kingdom and Canada, which realised that cost containment during the mid-1990s had strained their healthcare systems. All OECD governments are under continuous pressure to reconcile economic and health concerns because the public purse funds the bulk of health spending in most countries. The public share of health expenditure increased slightly in several countries, such as Italy and Switzerland, but remained virtually unchanged in most countries during recent years - accounting for 72.3% of total spending on average across OECD countries in 1997 and 73.1% in 2002.

Rapid advances in medical technologies, population ageing and rising public expectations were largely responsible for the health spending growth,  which was particularly notable in the area of pharmaceuticals. Between 1992 and 2002, spending on pharmaceuticals grew, on average, 1.3 times faster per year than total health expenditure, rising to  account for  between 9 and 37 percent of total health spending in OECD countries in 2002.
In spite of a growing awareness of the importance of prevention and public health, OECD countries spent on average only 2.8 percent of total health expenditure on organised public and private prevention programmes.
How many doctors and nurses are needed to ensure adequate supply of health services?

The present  or potential future shortage of health professionals, and its possible negative impact on timely access and quality of care, is also a concern in  a growing number of OECD countries.      

OECD Health Data 2004 shows that the number of doctors and nurses per capita varies substantially across countries. The number of practising physicians ranges from less than two per 1 000 people in Korea, Mexico and Turkey, to more than 4 in Greece and Italy, and for nurses the variation is even more marked. In an effort to increase the number of practising doctors and nurses, governments in several countries, such as Australia, England and Norway, introduced measures such as increasing the number of medical students, encouraging trained professionals to stay by enhancing their working conditions and/or remuneration, and recruiting from abroad.  But it will take several years before these measures produce the expected results.  

The number of physicians and nurses per capita necessary to ensure adequate care is not a fixed one - productivity and other factors must also be taken into account. But there are signs that fewer physicians per capita means longer waiting times for elective surgery.

The ratio of doctors to nurses also varies greatly across OECD countries, raising questions about the optimum skill mix in the delivery of health care. In some countries certain tasks traditionally performed by doctors are being transferred to highly qualified nurses without significant changes in the quality of care provided. For example, in the U.S., nurse practitioners in some states increasingly provide services, such as check-ups and gynaecological examinations, that are also provided by primary care physicians. 

Overweight and obesity problems, a growing risk factor in OECD countries

The number of overweight and obese people has increased in all OECD countries over the past two decades due to poor eating habits and lack of physical activity. Obesity is a known risk factor for diseases such as diabetes, hypertension, cardiovascular diseases, respiratory problems (asthma) and musculoskeletal diseases (arthritis). In several OECD countries, more than 50% of adults are now classified as being overweight or obese (body mass index over 25).  The United States has the highest rate of adults considered as overweight or obese (with 34% of adults being overweight and another 31% defined as obese in 1999-2000), followed by Mexico, the United Kingdom and Australia.                                                                             

OECD Health Data 2004 is available on CD-ROM, in a multilingual version (English, French, German and Spanish, with Italian and Russian added this year), for a single-user or a network installation. OECD Health Data 2004 is an essential tool, enabling health researchers and policy advisors in governments, the private sector and the academic community to carry out comparative analyses and draw lessons from cross-country comparisons of national health care systems. This thirteenth edition covers over 1 200 descriptive statistics and indicators. Key items span the period 1970 to 2001/2002, with many time series going back to 1960. An extensive documentation of definitions, national sources and estimation methods per country is included in the database. Free technical assistance, data and software updates are accessible via the Internet at

A limited number of CD-ROMs are available for journalists from the OECD Media Relations Division.

OECD Health Data 2004 is a co-production OECD-IRDES (formerly CREDES).
