"You're used to being the one that can fix things…": a qualitative snapshot of colorectal surgeons during COVID-19.
This viewpoint article reflects the narratives of 58 colorectal surgeons who engaged in an in-depth qualitative interview during the COVID-19 shutdown of elective surgeries. The goal for reporting these findings is to offer a snapshot of surgeon perspectives on the delays of elective surgeries and to give voice to surgeons who were unable to perform most or all their duties as a surgeon.

The risk of severe COVID-19 within households of school employees and school-age children.
Across the United States, school districts are grappling with questions of whether and how to reopen elementary and secondary schools in the 2020-21 academic year. Using pre-pandemic household data, the authors examined how often persons at risk of severe coronavirus disease 2019 (COVID-19) were connected to schools, either as employees or by living in the same households as school employees or school-age children.

Impact of the COVID-19 pandemic on healthcare workers' risk of infection and outcomes in a large, integrated health system.
Researchers assessed healthcare workers (HCW) risk for COVID-19 infection, hospitalization, and intensive care unit (ICU) admission. Participants were individuals who had tested for SARS-CoV-2 infection in a large academic healthcare system. The study found that, in a large healthcare system, HCW had similar odds for testing positive, but lower odds of hospitalization, compared to non-HCW. Patient-facing HCW had higher odds of a positive test.

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.

Variation in SARS-CoV-2 prevalence in U.S. skilled nursing facilities.
The objective of this study was to identify county and facility factors associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreaks in skilled nursing facilities (SNFs). The investigators concluded that larger SNFs and SNFs in areas of high SARS-CoV-2 prevalence were at high risk for outbreaks and must have access to universal testing to detect cases, implement mitigation strategies, and prevent further potentially avoidable cases and related complications.

Characterizing norovirus transmission from outbreak data, United States.
Norovirus is the leading cause of acute gastroenteritis outbreaks in the United States. In this study, the investigators estimated the basic (R(0)) and effective (R(e)) reproduction numbers for 7,094 norovirus outbreaks reported to the National Outbreak Reporting System (NORS) during 2009-2017 and used regression models to assess whether transmission varied by outbreak setting.

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.

Use of optimised dual statistical process control charts for early detection of surgical site infection outbreaks.
This study analyzed the use of optimized dual statistical process control (SPC) charts to predict surgical site infection (SSI) outbreaks. The researchers retrospectively applied an optimized pair of moving average (MA) SPC charts to all 30 SSI outbreaks previously identified and investigated from 2007 to 2015 in the Duke Infection Control Outreach Network (DICON), which is a network of more than 50 community hospitals. The dual MA SPC chart approach detected all 30 outbreaks at a median of 16 months prior to traditional surveillance detection.

COVID-19: pandemic contingency planning for the allergy and immunology clinic.
In the event of a global infectious pandemic, drastic measures may be needed that limit or require adjustment of ambulatory allergy services. However, no rationale for how to prioritize service shut down and patient care exists. A consensus-based ad-hoc expert panel of allergy/immunology specialists from the United States and Canada developed a service and patient prioritization schematic to temporarily triage allergy/immunology services. This paper describes the process, recommendations and feedback.

Network analysis of intra-hospital transfers and hospital onset Clostridium difficile infection.
This paper explores how social network analysis (SNA) software can be used to analyze intra-hospital networks of individuals with a healthcare associated infection (HAI) for further analysis in a GIS environment. The SNA analysis compared cases to controls which highlighted significant differences in the overall structure of the networks.

Quantifying the roles of vomiting, diarrhea, and residents vs. staff in norovirus transmission in U.S. nursing home outbreaks.
Norovirus transmissibility is poorly understood and the goal of this study was to examine transmission via vomiting, diarrhea, and patient exposures. Six nursing home outbreaks in South Carolina were examined from 2014 to 2016. Vomiting infected 2.12 times the number of individuals as non-vomiters, diarrhea 1.39 times, and resident cases infected 1.53 times the number of individuals as staff cases. This finding is important for not just nursing homes, but other sites of norovirus outbreaks such as cruise ships.

The potential economic value of a Zika vaccine for a woman of childbearing age.
The authors mapped the Zika vaccine and vaccination characteristic thresholds at which vaccination becomes cost effective, highly cost effective, and cost saving. They developed a Markov model to simulate a woman of childbearing age to follow the potential risk and clinical course of a Zika infection. They found that, in some cases, the vaccine was cost effective when the risk was as low as 0.015%, the cost was as high as $7,500, the efficacy was as low as 25%, and the duration of protection was 1 year. They concluded that the thresholds at which vaccination becomes cost effective and cost saving can provide targets for Zika vaccine development and implementation.
