Figures from the study showed that health insurance took up nearly 10% of all total spending in the poorest households – while it was just over 3% for the richest households.

The researchers found that poorer households, most with medical cards, were disproportionately affected by new medical card policies introduced during the economic downturn.

“This calls into question policies which have introduced new charges for medical card holders over the austerity period and in particular the imposition and increase of the prescription item levy”, said the study.
