Impact of the coronavirus disease 2019 (COVID-19) pandemic on the adherence to hand hygiene practice in hospitals-Data from a Swiss national surveillance system.

In >100,000 observations across Swiss acute-care hospitals, hand hygiene (HH) adherence significantly increased during the first coronavirus disease 2019 (COVID-19) wave. However, despite persisting COVID-19 activity, HH adherence returned to prepandemic levels over a 2-year observation period. These results indicate that training and support remains challenging.

Remdesivir in Coronavirus Disease 2019 patients treated with anti-CD20 monoclonal antibodies: a case series.

PURPOSE: COVID-19 patients on anti-CD20 treatment can suffer a delayed viral clearance and worse clinical outcome. We aim to present our experience with remdesivir treatment in anti-CD20-treated patients with prolonged symptoms, a patient population for which no data from randomized controlled trials are available. METHODS: From the beginning of the pandemic until February 2021, we included all consecutive patients from our healthcare network on anti-CD20 treatment with prolonged COVID-19 symptoms, who received remdesivir. Patient informed consent was gathered and patients' charts were reviewed to collect baseline data, COVID-19 history including time of symptom onset, diagnosis, data on treatment and disease course. Patients or their next of kin were contacted in March 2022 to assess long-term outcomes. RESULTS: We included 11 patients, who received remdesivir at a median of 33 days after diagnosis. Eight patients showed clinical improvement along with reductions in viral loads, one patient with relapsing infection recovered after administration of convalescent plasma, and two patients died. No clinical relapses were reported (median follow-up 13 months), while follow-up PCRs were not performed. One patient died of underlying malignancy 8 months after recovery from COVID-19. CONCLUSIONS: We observed a benefit of antiviral therapy in a majority of COVID-19 patients on anti-CD20 treatment, without any clinical relapses in the 1-year follow-up. Although these data suggest that remdesivir might be a promising management option in patients with delayed viral clearance, the lack of a control group is an important limitation of the study design. TRIAL REGISTRATION: Ethikkommission Ostschweiz, Scheibenackerstrasse 4, CH-9000 St. Gallen approved this case series. Project-ID 2021-00349 EKOS 21/027.

It is complicated: Potential short- and long-term impact of coronavirus disease 2019 (COVID-19) on antimicrobial resistance-An expert review.

As of December 2021, the coronavirus disease 2019 (COVID-19) pandemic has claimed millions of deaths and caused disruptions in health systems around the world. The short- and long-term effects of COVID-19 on antimicrobial resistance (AMR), which was already a global threat before the pandemic, are manifold and complex. In this expert review, we summarize how COVID-19 might be affecting AMR in the short term (by influencing the key determinants antibiotic use, infection control practices and international/local mobility) and which additional factors might play a role in the long term. Whereas reduced outpatient antibiotic use in high-income countries, increased awareness for hand hygiene, and reduced mobility have likely mitigated the emergence and spread of AMR in the short term, factors such as overuse of antibiotics in COVID-19 patients, shortage of personal protective equipment, lack of qualified healthcare staff, and patient overcrowding have presumably facilitated its propagation. Unsurprisingly, international and national AMR surveillance data for 2020 show ambiguous trends. Although disruptions in antibiotic stewardship programs, AMR surveillance and research might promote the spread of AMR, other developments could prove beneficial to the cause in the long term. These factors include the increased public awareness for infectious diseases and infection control issues, the strengthening of the One Health perspective as outlined by the Centers for Disease Control and Prevention, and the unprecedented number of international research collaborations and platforms. These factors could even serve as leverage and provide opportunities to better combat AMR in the future.
