With the publication of the revised figures for the years 2021 to 2023, the current revision is not completely at an end. The table showing the price and volume development of health and social care expenditure  will be revised in the course of 2025. In addition, we will be working to add older years to the tables currently published. In view of the far-reaching changes involved in this revision (the coverage of the entire section Q, the use of claims and the methodology to correct for double counting), it is not possible to compile the entire 1998-2020 series in the same way as has now been done for the years 2021-2023. The expectation is that 2020 and 2019 will be added in any event, with further research being needed to establish whether it is also possible to add the years 2016-2018. Because the figures before revision (for the years 1998-2022) will remain available on StatLine under ‘Archive’), this means that for multiple years there will be figures arrived at using both the old and the new approaches. 

As was stated in the introduction, a revision takes place every five years. This means that no major changes will be implemented in the interim. Because revision activities often have a long lead time, consideration is already being given to further improvements of the statistics. Based on the experiences gained during the current revision, a number of topics are being considered. Some examples:

• Acquiring greater insight into the size of groups of providers of care activities delivered under the Wmo and the Child and Youth Act and the distribution between them, and into alignment with the figures for the social domain in the CBS statistics on the finances of municipalities. The use of claims data can undoubtedly contribute to that. 
• Acquiring greater insight into the level of out-of-pocket payments, and their distribution across both provider groups and care types. This relates not to the insurance excess and personal contributions under the different care acts, but to what people themselves pay for uninsured care. The possibility will be explored of obtaining greater insight into out-of-pocket payments for care in the next round of the CBS Budget Survey, which will take place in 2026. Efforts will also be made to identify other potential sources on this subject.
• Improving and possibly expanding the current figures by care type – for example, making the figures on the ‘Prevention’ care type more complete and possibly adding a care (sub)type for youth health care. 
• Making use of the information generated as a result of the expansion of the population of healthcare providers required to file annual corporate social responsibility reports, starting with the 2024 reporting year. Since as part of that accountability requirement, income is reported per Act of Parliament, it may be possible to further improve the financing distribution in the Health and Social Care Accounts.
• Acquiring greater insight into the subclasses of section Q for which little data is currently available, particularly with regard to the breakdown by care types. Even more intensive use of annual reports and the classification of units using online information may offer potential benefits, but would be highly labour-intensive.
