There is enormous variability between the highest income quintile (3.9%) and the lowest (18.7%), highlighting unequal access to services experienced across income groups (Figure 10). Among the poorest quintile it reached 17.4%, the highest in the EU where the average is just 4.1%. Moreover, a copayment for ambulatory visits (EUR 5) was revoked in 2015 following concerns about its impact on access. The rate of impoverishment due to out-of-pocket payments has been rising steadily since 2004, and affected 3% of all households in 2014 (Figure 13).
