Disability care facilities

Where do the numbers come from?

The figures on disability care are provided by the National Institute for Public Health and the Environment (RIVM). RIVM supplies the figures as an open data file.

How are these figures determined?

Positive tests among residents
From 1 July 2020, the GGDs registers whether a newly-infected person is resident in a disability care facility. RIVM considers a person to be a disability care home resident if they are registered as such in the central OSIRIS database. If this is not known, RIVM counts the person as a disability care home resident if they are not a health worker and:

  • the location of the infection is a disability care home, or
  • they can be linked to the disability care home on the basis of information given in free text fields.

The word ‘locations’ refers to the 2,586 care homes in the Netherlands that are registered by Zorgkaart Nederland as providing residential care to people with disabilities. The total number of locations per safety region is provided by RIVM. Locations with the same postcode are counted as one location. The same method is used to determine the number of infected locations. It is necessary to know the total number of locations per safety region in order to calculate the percentage of locations that are infected. To calculate the total number of locations nationwide, we add up the totals of all safety regions.

Deceased residents
We show the number of deaths among disability care facility residents by the date of death. If we do not know the date of death, which is sometimes the case, we do not show the death on the dashboard.

Average over 7 days
The graph showing the number of confirmed cases among residents and the graph showing the number of deaths among residents shows the average over 7 days.

Adjustments and corrections

Change in delivery of data from 1 January 2023

As of 1 January 2023, if a test result is positive, less information is collected.

This information was collected by the GGDs and was an important source of information at an earlier stage of the COVID-19 pandemic. In the meantime, other monitoring instruments and information sources (such as Infectieradar, sewage and germ surveillance and hospital registrations) have become important or have been further developed.

The page Disability care will no longer be updated. Available information will be shown on a new page about Vulnerable groups and 70+.

If the epidemiological situation changes and additional data sources are required, the GGDs can be asked to provide additional information.

Changes in the figures
For reports of confirmed cases amongst residents without a stated first day of illness, the RIVM determines a calculated first day of illness. This calculation method has been adjusted from 16 July 2021. The figures for the number of infected locations have been retroactively adjusted on the dashboard.

As of November 2021, due to the scaled-down contact tracing, it will not be standard practice to check whether people live in an institution. This leads to an underreporting of the number of positively tested residents of disability care facilities.
