Experts have warned against the pandemic burden on healthcare workers early on, however little is known about the evolution of this burden with time, in addition to the long-term effects of post-COVID symptoms in healthcare workers. Staff at the Geneva University Hospitals in Switzerland had an online follow-up in July and December 2021, on their physical and mental health, quality of life and functional capacity using validated scales. Descriptive analyses compared the prevalence of symptoms, functional impairment and quality of life in SARS-CoV-2 positive and negative individuals at baseline and at follow-up.

COVID-19 had a huge impact on healthcare systems globally. Institutions, care teams and individuals made considerable efforts to adapt their practices. The present longitudinal, mixed-methods study examined a large sample of healthcare institution employees in Switzerland.

Background: There is ongoing uncertainty regarding transmission chains and the respective roles of healthcare workers (HCWs) and elderly patients in nosocomial outbreaks of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in geriatric settings.

Methods: We performed a retrospective cohort study including patients with nosocomial coronavirus disease 2019 (COVID-19) in four outbreak-affected wards, and all SARS-CoV-2 RT-PCR positive HCWs from a Swiss university-affiliated geriatric acute-care hospital that admitted both Covid-19 and non-Covid-19 patients during the first pandemic wave in Spring 2020. We combined epidemiological and genetic sequencing data using a Bayesian modelling framework, and reconstructed transmission dynamics of SARS-CoV-2 involving patients and HCWs, to determine who infected whom.

Healthcare workers have potentially been among the most exposed to SARS-CoV-2 infection as well as the deleterious toll of the pandemic. This study has the objective to differentiate the pandemic toll from post-acute sequelae of SARS-CoV-2 infection in healthcare workers compared to the general population. The study was conducted between April and July 2021 at the Geneva University Hospitals, Switzerland.

Healthcare workers (HCWs) have significantly suffered during the COVID-19 pandemic, reporting a high prevalence of anxiety, depression and post-traumatic stress disorder (PTSD). We investigated with this survey whether HCWs benefitted from supportive measures put in place by hospitals and how these measures were perceived. This cross-sectional survey, which was conducted during the first wave of COVID-19 at the Geneva University Hospitals, Switzerland, between May and July 2021, collected information on the use and perception of practical and mental health support measures provided by the hospital.

Article Synopsis
  • The study investigated how both work-related and community exposures contributed to SARS-CoV-2 infections among staff at a long-term care facility in Switzerland during the early phase of the pandemic (March-June 2020).
  • Researchers analyzed seroprevalence data from volunteer employees and studied transmission dynamics during a COVID-19 outbreak, identifying factors related to seropositivity and the genetic similarities of virus strains.
  • Results showed that out of 176 participants, 17% tested positive, with exposure to COVID-19 patients and community cases being significant risk factors, highlighting the crucial role of both work and community interactions in spreading the virus among healthcare workers.

The COVID-19 pandemic's first wave required considerable adaptation efforts on the part of healthcare workers. The literature on resilient healthcare describes how the collective regulation strategies implemented by frontline employees make essential contributions to institutions' abilities to cope with major crises. The present mixed-methodology study was thus conducted among a large sample of employees in a variety of Swiss healthcare institutions and focused on problematic real-world situations experienced by them and their managers during the pandemic's first wave.

Background: Intensive care workers are known for their stressful work environment and for a high prevalence of mental health outcomes. The aim of this study was to evaluate the mental health, well-being and changes in lifestyle among intensive care unit (ICU) healthcare workers (HCW) during the first wave of the COVID-19 pandemic and to compare these results with those of HCW in other hospital units. Another objective was to understand which associated factors aggravate their mental health during the COVID-19 outbreak.

Article Synopsis
  • A young healthy female physician experienced reinfection with SARS-CoV-2 six months after her first mild COVID-19 episode, confirmed by whole-genome sequencing.
  • Antibody testing showed that while neutralizing antibodies declined after the first infection, they surged again after reinfection, and strong memory B-cell responses were observed.
  • This case highlights a potential risk for medical personnel due to the rapid decline of neutralizing antibodies, suggesting that reinfection can enhance immune responses; further research is needed to understand the duration of protection.

Background Return to work with or after a chronic disease is not a very well understood process, influenced by a variety of personal, professional, societal and medical factors. The aim of this study is to identify predictors for return to work 12 months after a solid organ transplant applying a bio-psycho-social model. Methods This study is based on patients included in the Swiss Transplant Cohort Study, a national prospective multicentre cohort, who underwent a first solid organ transplant (kidney, liver, heart, lung).
