Headline indicators for monitoring the performance of health systems: findings from the european Health Systems_Indicator (euHS_I) survey.

HSPA indicators from different initiatives largely overlap and public health indicators dominate over health systems aspects. The survey allowed to quantify overlaps and gaps in HSPA indicators, their expert allocation to domain areas and establishment of an informed hierarchy structure. Yet, results show that more multidisciplinary work is needed to ensure the availability of accurate efficiency indicators which are comparable across countries.
