Non-Pharmaceutical Interventions on COVID-19 in Workers and Residents of Nursing Homes in Geneva: A Mixed Qualitative and Quantitative Study Menon, Lakshmi Krishna; Wisniak, Ania; Regard, Simon; Stringhini, Silvia; Guessous, Idris; Balavoine, Jean-François; Kherad, Omar; The SEROCoV-WORK + Study Group
Abstract
The objective of this study was to examine the impact of varying levels of non-pharmaceutical interventions (NPIs) on COVID-19 transmission in nursing homes during the first wave of the pandemic. Background/Objectives: The primary aim involved exploring qualitative insights from staff and management regarding the implementation of NPIs. The secondary aim was to determine the cumulative incidence of PCR-confirmed COVID-19 cases among residents. Incident rate ratios (IRRs) were the calculated levels of NPI restrictiveness. Methods: We used a mixed methodology to identify factors that might have affected COVID-19 expansion in nursing homes in the canton of Geneva, Switzerland. For the qualitative component, we interviewed the Attending Physicians and/or Director of each nursing home. In the quantitative component, we calculated incident rate ratios (IRRs) for infection between the three levels of COVID-19-related measures taken in these nursing homes, and the cumulative incidence of PCR-confirmed COVID-19 cases in their resident population. This study was conducted in 12 nursing homes located in the canton of Geneva, Switzerland, between 1 March 2020, and 1 June 2020. Results: Most nursing homes mandated NPIs for their staff and residents during the first wave of COVID-19. We found an equal distribution of maximally (n = 4), moderately (n = 4), and minimally (n = 4) restrictive NPIs for nursing home workers and residents. The extent of NPIs implemented was not shown to be significantly associated with the cumulative incidence of COVID- 19 cases among residents (maximally restrictive IRR = 3.90, 95%CI 0.82–45.54, p = 0.184; moderately restrictive IRR = 3.55, 95%CI 0.75–41.42, p = 0.212; minimally restrictive IRR = reference). Conclusions: Nursing homes in our study showed high variability in which NPIs, and to what extent, they implemented, with no significant relationship between the restrictiveness of NPIs and COVID-19 incidence among nursing home residents. This suggests that other factors influence the transmission of COVID-19 in these settings. Future research should explore additional determinants and the balance between strict NPIs and the overall well-being of residents.

The objective of this study was to examine the impact of varying levels of
non-pharmaceutical interventions (NPIs) on COVID-19 transmission in nursing homes
during the first wave of the pandemic. Background/Objectives: The primary aim involved
exploring qualitative insights from staff and management regarding the implementation of
NPIs. The secondary aim was to determine the cumulative incidence of PCR-confirmed
COVID-19 cases among residents. Incident rate ratios (IRRs) were the calculated levels of
NPI restrictiveness. Methods: We used a mixed methodology to identify factors that might
have affected COVID-19 expansion in nursing homes in the canton of Geneva, Switzerland.
For the qualitative component, we interviewed the Attending Physicians and/or Director
of each nursing home. In the quantitative component, we calculated incident rate ratios
(IRRs) for infection between the three levels of COVID-19-related measures taken in these
nursing homes, and the cumulative incidence of PCR-confirmed COVID-19 cases in their
resident population. This study was conducted in 12 nursing homes located in the canton
of Geneva, Switzerland, between 1 March 2020, and 1 June 2020. Results: Most nursing
homes mandated NPIs for their staff and residents during the first wave of COVID-19. We
found an equal distribution of maximally (n = 4), moderately (n = 4), and minimally (n = 4)
restrictive NPIs for nursing home workers and residents. The extent of NPIs implemented
was not shown to be significantly associated with the cumulative incidence of COVID-
19 cases among residents (maximally restrictive IRR = 3.90, 95%CI 0.82–45.54, p = 0.184;
moderately restrictive IRR = 3.55, 95%CI 0.75–41.42, p = 0.212; minimally restrictive IRR
= reference). Conclusions: Nursing homes in our study showed high variability in which
NPIs, and to what extent, they implemented, with no significant relationship between
the restrictiveness of NPIs and COVID-19 incidence among nursing home residents. This
suggests that other factors influence the transmission of COVID-19 in these settings. Future research should explore additional determinants and the balance between strict NPIs and
the overall well-being of residents.
