Project with no end date

In short

When people with care needs are no longer able to live at home on their own, (long-term) admission to a long-term care facility (e.g. a nursing home) becomes necessary. During the care process, there is a risk that these residents will contract an infection, referred to as healthcare-associated infections. Based on various studies, we document these healthcare-associated infections, the associated antibiotic treatments and the problem of antibiotic resistance (bacteria that become insensitive to antibiotics) in these healthcare institutions. 

Project summary

Healthcare-associated infections are infections that occur after healthcare exposure and often, but not always, result from this exposure. Residents in long-term care facilities are more likely to contract healthcare-associated infections because of the long length of stay and, therefore, also the exposure to care in these institutions. Moreover, the residents in these institutions are often elderly. They are especially vulnerable due to a reduced immune system, underlying disorders and/or physical limitations. 

Infections in these individuals are often more complicated and are frequently treated with antibiotics. Frequent and incorrect use of these antibiotics can lead to antibiotic resistance. In the case of antibiotic resistance, the bacteria have become insensitive to antibiotics and these medicines are therefore no longer effective. In the course of care, the frequent contacts between residents and care staff also increase the chance of infections and/or resistant germs being transmitted.  

For several years, a great deal of effort has been put into documenting the problem of healthcare-associated infections, antibiotic use and antibiotic resistance in Belgian long-term care facilities

Healthcare-associated infections, antibiotic resistance and the use of antimicrobials in long-term care facilities

Sciensano has already organized three (2005, 2011 and 2015) national prevalence studies (measurement of a disease or condition in a particular population at a particular time) in order to document the carrier-status of methicillin-resistant Staphylococcus aureus (MRSA) and other resistant germs in Belgian nursing homes.

Following studies on the use of antimicrobials in nursing homes (ESAC NH), Sciensano, in collaboration with the European Center for Disease Prevention and Control (ECDC), is organizing prevalence studies in European long-term care facilities. The aim of these ‘Healthcare-associated Infections and Antimicrobial use in Long-Term Care Facilities’ (HALT) studies is to measure the incidence of healthcare-associated infections and the use of antimicrobials in long-term care facilities using a standardized methodology. 

Three European HALT studies have already taken place (2010, 2013 and 2016–2017). HALT PSY took place in 2017: a study specifically aimed at psychiatric hospitals and psychiatric wards in acute hospitals in Belgium. In anticipation of a new European study, Sciensano organized a national HALT study in 2021.

The development of COVID-19 in Belgian long-term care facilities

Following the corona crisis, Sciensano, in collaboration with the regional authorities, is also monitoring the development of COVID-19 in Belgian long-term care facilities (mainly nursing homes). Via this surveillance, we measure:

  • the incidence (number of new cases in a given period) and prevalence (number of cases at a given time) of confirmed COVID-19 cases in residents and members of staff
  • the number of COVID-19 hospital admissions and deaths among residents
  • the absenteeism due to COVID-19 among the staff.

In addition, the surveillance aims to identify potential infection clusters in these institutions so that the regional authorities can investigate them further. 

Finally, Sciensano is carrying out, in collaboration with the Flemish Institute for Technological Research (VITO), the AIRCO study. This study is running from October 2021 to October 2022. In the context of this study, we measure ventilation and indoor air quality in 20 Belgian nursing homes using measuring devices in five different rooms. We also take air samples and samples from ventilation grilles. In addition, we ask questions about and observe the ventilation habits and infection prevention measures in the nursing homes.
