Background
In European ageing societies, the national expenditure on institutional long-term care (LTC) has been growing for decades, currently exceeding 1% of the GDP in many countries. At the same time, however, comparative analyses of (day) prices in the nursing and residential care facilities (NRCFs) are still lacking. The data reported by international databases vary substantially in the services they cover which makes cross-country comparisons very difficult.

Methods
We combine publicly available data from Eurostat (System of Health Accounts), OECD and national sources on the number of recipients of LTC in NRCFs, the number of beds in NRCFs and the expenditure on LTC in NRCFs in over 20 European countries. Our aim is to compute internationally comparable daily prices of LTC in NRCFs using gross-costing approach. We first validate the data by cross-checking and documenting which health care functions and providers are reported by each country. Second, based on that we identify countries with comparable data and, third, perform a cross-country comparison of the daily spending on LTC in NRCFs.

Results
The reported data vary substantially with respect to their coverage. For instance, while some countries include NRCFs for all disabled people at all ages, others focus only on the NRCFs for the elderly. The ways the beds and the recipients are counted also show substantial variation. Moreover, we found inconsistencies in the reported numbers not only between but also within countries.

Conclusions
The considerable cross-country diversity in the LTC provision within the NRCFs poses inevitable challenges to international standardised reporting. Our analysis shows, however, that at least some of the challenges can be overcome by, e.g. improving the consistency of the reported numbers at the country level.

Key messages
• A consistent definition application markedly improves the comparability of data on LTC in NRCFs.
• Given the rising demand for and economic importance of the LTC sector standardised data on NRCF services are greatly needed.
