Current evidence for infection prevention and control interventions in emergency medical services: a scoping review.
This study’s aim was to summarize current evidence from the United States on the effectiveness of practices and interventions for preventing, recognizing, and controlling occupationally acquired infectious diseases in Emergency Medical Service (EMS) clinicians. A database search was conducted for literature published January 2006 through March 15, 2022 to search for studies in the United States that involved EMS clinicians and firefighters, reported on one or more workplace practices or interventions that prevented or controlled infectious diseases, and included outcome measures. Eleven observational studies reported on infection prevention and control (IPC) practices providing evidence that hand hygiene, standard precautions, mandatory vaccine policies, and on-site vaccine clinics are effective. Less frequent handwashing and less frequent hand hygiene after glove use were positively correlated with nasal colonization of Methicillin-resistant Staphylococcus aureus (MRSA). Lack of personal protective equipment (PPE) or PPE breach were correlated with higher severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) seropositivity and virus 2 (SARS-CoV-2) seropositivity. Workers were more likely to be vaccinated against influenza if their employer offered the vaccine. Vaccination rates for H1N1 influenza increased with the use of active, targeted education modules.

Reimagining infection control in U.S. nursing homes in the era of COVID-19.
This paper provides an overview of nursing home (NH) infection and control, reviews the 2016 CMS changes to federal regulations, and proposes recommendations to sustain improvements. COVID-19 put further pressure on nursing homes who were already strained by rising numbers of infections from C. difficile and multidrug-resistant organisms. The author puts out a call for reimagining infection prevention and control using the Systems Engineering Initiative for Patient Safety framework. Additional recommendations are made to enhance NH infection prevention and control programs in the areas of people, tasks, tools, organization, built environment, and external environment.

Emergent themes from a quality improvement programme for CLABSI/CAUTI prevention in ICUs amid the COVID-19 pandemic.
In this study, researchers summarized themes for maintaining infection prevention activities learned from the implementation of a quality improvement (QI) program during the COVID-19 pandemic. They concluded that future shocks such as the pandemic must be anticipated, and the healthcare system must be resilient to the resulting disruptions to healthcare-associated infection prevention activities. Their study encountered four themes for successful maintenance of infection prevention activities during the current pandemic: the value of a pre-existing infection prevention infrastructure; a flexibility in approach; broad buy-in for maintaining QI programs; and the facilitation of idea-sharing.

State social distancing restrictions and nursing home outcomes.
This study examined how state orders for social distancing to curb COVID-19 morbidity and mortality affected nursing home patients and what potential negative health consequences they may have had. The authors examined state social distancing restrictions from June to August of 2020 and their associations with the weekly numbers of new COVID cases, new COVID deaths, and new non-COVID deaths in nursing homes across the US. They found that stronger state social distancing measures were associated with improved outcomes, reduced across-facility disparities in COVID outcomes, and somewhat increased non-COVID-19 death rates. The estimates for non-COVID-19 deaths were sensitive to alternative model specifications.

The benefits of vaccinating with the first available COVID-19 coronavirus vaccine.
This study’s objective was to determine quantitatively the benefits of early vaccination for COVID-19 even if later on in the pandemic a latter vaccine has substantially higher efficacy. The team developed this model in 2020 before vaccinations became available. For example if a vaccine with 50% efficacy becomes available when 10% of the population has already been infected, waiting until 40% of the population are infected for a vaccine with 80% efficacy results in 15.6 million additional cases and 1.5 million additional hospitalizations, costing $20.6 billion more in direct medical costs and $12.4 billion more in productivity losses.

Effectiveness of interventions to reduce COVID-19 transmission in a large urban jail: a model-based analysis.
The authors sought to estimate the impact of various mitigation strategies on COVID-19 transmission in a US jail beyond those offered in national guidelines. They found that depopulation, single celling, and asymptomatic testing within jails can be effective strategies to mitigate COVID-19 transmission in addition to standard public health measures. They recommended that decision makers prioritize reductions in the jail population, single celling, and testing asymptomatic populations as additional measures to manage COVID-19 within correctional settings.

Estimation of COVID-19 basic reproduction ratio in a large urban jail in the United States.
The purpose of this study was to estimate the basic reproduction ratio () of SARS-CoV-2 inside a correctional facility early in the COVID-19 pandemic. The investigators concluded that the high of SARS-CoV-2 in a large urban jail highlighted the importance of including correctional facilities in public health strategies for COVID-19. The investigators suggested that in the absence of more aggressive mitigation strategies, correctional facilities will continue to contribute to community infections.

Masks for prevention of respiratory virus infections, including SARS-CoV-2, in health care and community settings : a living rapid review.
This study examined the effectiveness of N95, surgical, and cloth masks in community and health care settings for preventing respiratory virus infections, including coronavirus. The effects of reuse or extended use of N95 masks was also studied. The authors used multiple electronic databases, including the World Health Organization COVID-19 database and medRxiv preprint server (2003 through 2020), and reference lists. Randomized trials of masks and risks for respiratory virus infection were included. The studies were abstracted and methodological limitations were assessed by one reviewer, with a second reviewer providing verification. Thirty-nine studies with 33,867 participants were included. No studies were found that evaluated reuse or extended use of N95 masks. The studies showed that COVID-19 and MERS probably decreased with use versus nonuse and possibly decreased with N95 versus surgical mask use. Random trials in community settings found not much difference between N95 versus surgical masks. The studies’ findings were not definitive.

Vaccine efficacy needed for a COVID-19 coronavirus vaccine to prevent or stop an epidemic as the sole intervention.
This study examined the needed efficacy and coverage of a COVID-19 vaccine to prevent or stop the pandemic. Simulation experiments were conducted at 60-80% efficacy rates. At 60% efficacy, vaccination coverage needs to be 100%. If the coverage rate is reduced to 75%, the efficacy needs to be 70% and up to 80% when coverage drops to 60%. These findings show that the vaccine needs to have at least an efficacy rate of 70% to prevent an epidemic and at least 80% to extinguish an epidemic without any other measures such as social distancing.

Choosing Wisely in the COVID-19 era: preventing harm to healthcare workers.
This paper highlights the 5 top recommendations developed for hospitals in the COVID-19 era as part of the Choosing Wisely® campaign. This top 5 list of overuse practices in hospital medicine can lead to harm of both patients and healthcare workers. The recommendations include: 1) Do not obtain nonurgent labs in separate blood draws if they can be batched together; 2) Do not use bronchodilators unless there is active obstructive airway disease; 3) Do not use posteroanterior and lateral chest X-ray (CXR) as initial imaging, use a portable CXR instead; 4) Avoid in-person evaluations in favor of virtual communication unless necessary; and 5) Do not delay goals of care conversations for hospitalized patients who are unlikely to benefit from life-sustaining treatments.
