Background: Numerous individual and organizational factors can influence the spread of SARS-CoV-2 infection in Long Term Care Facilities (LTCFs). A range of outbreak control measures are still implemented in most facilities involving administrations, staff, residents and their families. This study aims to evaluate which measure could influence the transmission of SARS-CoV-2 infection among residents during the period March 2021-June 2022., Methods: We enrolled 3,272 residents aged ≥60 years. The outbreak control measures adopted to prevent or manage the infection included entry regulations, contact-regulating procedures, and virological surveillance of residents and staff. The association between LTCFs' and participants' characteristics with new cases of COVID-19 infections was analyzed using multilevel logistic regression models., Results: In 33.8% of the facilities 261 cases of SARS-CoV-2 infection were reported. Among participant characteristics, gender and age were not associated with SARS-CoV-2 infection, while having received the vaccine booster dose was protective against infection [Odds Ratio (OR) = 0.34, 95% Confidence Interval (CI) 0.12-0.99, p = 0.048]. In addition, the implementation of protected areas for family visits was associated with a significant reduction of the probability of infections (OR = 0.18, 95% CI 0.03-0.98, p = 0.047). Overall, about 66% of the variability in the probability of SARS-CoV-2 infection during the observational period may be due to facility structure characteristics and 34% to the participant characteristics., Conclusions: These data showed that vaccination booster doses and family visit restriction-control are still needed to make the LTCFs safer against SARS-CoV-2 infection., Competing Interests: SD was employed by Bluecompanion Ltd.

The COVID-19 pandemic has changed routine care practice for older persons, especially in those with frailty living in long term care (LTC) facilities. Due to the high mortality rates of Nursing home (NH) residents during the first wave of the COVID-19 pandemic, priority for COVID-19 vaccinations was given to this vulnerable population. However, the safety and efficacy of such vaccines in older frail elders remains questionable due to the fact that initial randomized clinical trials (RCTs) for such vaccines did not include this population. This type of discrimination in patient participation in RCTs continues and has been recognized in the literature. Nevertheless, in the context of a worldwide emergency, COVID-19 vaccination in older persons living in LTC facilities may provide a solid basis to protect against negative outcomes, such as COVID-19 infection and death. In this report, we present the protocol of the GeroCovid Vax study, an Italian study that began in February 2021 which is aimed at investigating the safety and efficacy of the anti-SARS-CoV-2 vaccinations in older persons living in LTCs. This protocol specially aims to continuously and closely monitor events related to- and following- the anti-SARS-CoV-2 vaccination in elderly living in LTC facilities. In this report, we will provide information related to the study protocol and describe baseline characteristics of the sample., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Ltd.
