Health-care spending was 6.1% of GDP in 2008 (the latest year for which data is available) compared to an average of 9.3% of GDP across OECD countries in 2011. This translates to health spending of USD 906 per person (adjusted for PPP) in Turkey, roughly one quarter of the USD PPP 3 322 spent on average among OECD countries in 2011 (Figure 4.1). While spending increased across all major categories of health-care providers, hospitals and the retail sale of medical goods (pharmaceuticals, optical, hearing and medical aids and appliances), sustained growth rates of 11% and 5% a year respectively between 2003 and 2008.
