Background Infectious disease outbreaks are common in care homes, often with substantial impact on the rates of infection and mortality of the residents, who primarily are older people vulnerable to infections. There is growing evidence that organisational characteristics of staff and facility might play a role in infectious disease outbreaks however such evidence have not previously been systematically reviewed. Therefore, this systematic review aims to examine the impact of facility and staff characteristics on the risk of infectious disease outbreaks in care homes. Methods Five databases (MEDLINE, EMBASE, ProQuest, Web of Science, CINAHL) were searched. Studies considered for inclusion were of any design reporting on an outbreak of any infectious disease in one or more care homes providing care for primarily older people with original data on: facility size, facility location (urban/rural), facility design, use of temporary hired staff, staff compartmentalizing, residence of staff, and/or nursing aides hours per resident. Retrieved studies were screened, assessed for quality using CASP, and analysed employing a narrative synthesis. Results Sixteen studies (8 cohort studies, 6 cross-sectional studies, 2 case-control) were included from the search which generated 10,424 unique records. COVID-19 was the most commonly reported cause of outbreak (n = 11). The other studies focused on influenza, respiratory and gastrointestinal outbreaks. Most studies reported on the impact of facility size (n = 11) followed by facility design (n = 4), use of temporary hired staff (n = 3), facility location (n = 2), staff compartmentalizing (n = 2), nurse aides hours (n = 2) and residence of staff (n = 1). Findings suggest that urban location and larger facility size may be associated with greater risks of an infectious disease outbreak. Additionally, the risk of a larger outbreak seems lower in larger facilities. Whilst staff compartmentalizing may be associated with lower risk of an outbreak, staff residing in highly infected areas may be associated with greater risk of outbreak. The influence of facility design, use of temporary staff, and nurse aides hours remains unclear. Conclusions This systematic review suggests that larger facilities have greater risks of infectious disease outbreaks, yet the risk of a larger outbreak seems lower in larger facilities. Due to lack of robust findings the impact of facility and staff characteristics on infectious disease outbreaks remain largely unknown. Prospero CRD42020213585.

The COVID‐19 pandemic has particularly affected older adults and resulted in high rates of infections and deaths in care homes. We have conducted a case study in which three managers of care homes for older adults in central Stockholm have shared their thoughts on the media coverage of care homes for older adults during the COVID‐19 pandemic. We analysed the data using conventional content analysis and identified three themes and five categories. The results show that the managers experienced the media coverage of care homes during the pandemic to be negative and incomplete, causing feelings of sadness and shame amongst themselves and their staff. The negative media coverage further generated added workload as they had to arrange for discussions to answer questions by staff and close relatives of the residents. Informants also thought that there is a lack of knowledge about the role of care homes and subsequently what to expect of them. Finally, informants reported that the pandemic might create an opportunity for system‐level policy changes. In light of this, we discuss possible victim blaming of staff and how greater public awareness of the care home sector could facilitate for a debate on policy changes and the low social status of caring for older adults.
