The Lived Experience of Standards Implementation in New York City Schools, 2011

The College and Career Readiness Standards, referred to as the Common Core Learning Standards (CCLS) in New York City, are increasingly the focus of educational reform efforts across the United States. Each year for the past several years, the New York City Department of Education (NYCDOE) has created a set of focusing expectations for schools in order to guide their engagement with the CCLS. In the 2011-12 school year, which is the focus of this report, the New York Citywide Instructional Expectations (CIEs) asked schools to engage in two central activities. First, teachers in grade levels or subject areas were asked to collaboratively examine student work and analyze the gaps between current curriculum, instructional practice, and student performance relative to the expectations of the Standards. Second, schools were asked to identify and implement performance-based assessments, or “tasks,” within a CCLS-aligned curricular unit, such that all students would experience at least one task in literacy and one in mathematics. The NYCDOE designed these activities as a set of carefully chosen opportunities for schools to engage with the more rigorous expectations for teaching and learning embodied in the Standards. The hope was that, by engaging with these learning opportunities, school staff would develop a deeper, shared understanding of the Standards, and could begin to address the scope of change necessary to meet the higher expectations. CPRE’s evaluation of CCLS implementation in New York City in 2011-12 allowed us to examine how a diverse sample of 16 elementary and middle schools engaged with the CIEs

Extended Reality Head-Mounted Displays Are Likely to Pose a Significant Risk in Medical Settings While Current Classification Remains as Non-Critical

Extended reality (XR) devices, including virtual and augmented reality head-mounted displays (HMDs), are increasingly utilised within healthcare to provide clinical interventions and education. Currently, XR devices are utilised to assist in reducing pain and improving psychological outcomes for immunocompromised patients in intensive care units, palliative care environments and surgical theatres. However, there is a paucity of research on the risks of infection from such devices in healthcare settings. Identify existing literature providing insights into the infection control risk XR HMDs pose within healthcare facilities and the efficacy of current infection control and cleaning procedures. Three databases (PubMed, Embase and CINAHL) in addition to Google Scholar were systematically searched. A total of seven studies were identified for this review. Microorganisms, including pathogenic bacteria (e.g., Staphylococcus aureus and Pseudomonas aeruginosa), were found to be present on XR HMDs. Published cleaning and infection control protocols designed to disinfect XR HMDs and protect users were heterogeneous in nature. Current cleaning protocols displayed varying levels of efficacy with microbial load affected by multiple factors, including time in use, number of users and XR HMD design features. In healthcare settings, fitting XR HMDs harbouring microorganisms near biological and mucosal entry points presents an infection control risk. An urgent revision of the Spaulding classification is required to ensure flexibility that allows for these devices to be reclassified from ‘Non-critical’ to ‘Semi-Critical’ depending on the healthcare setting and patient population (surgery, immunocompromised, burns, etc.). This review identified evidence supporting the presence of microorganisms on XR HMDs. Due to the potential for HMDs to contact mucosal entry points, devices must be re-considered within the Spaulding classification as ‘Semi-critical’. The existence of microbial contaminated XR HMDs in high-risk medical settings such as operating wards, intensive care units, emergency departments, labour and delivery wards and clinical areas with immunosuppressed patients requires urgent attention. Public health authorities have a duty of care to develop revised guidelines or new recommendations to ensure efficient sanitation of such devices

Ultraviolet-c-based mobile phone sanitisation for global public health and infection control

Introduction. Mobile phones act as fomites that pose a global public health risk of disseminating microorganisms, including highly pathogenic strains possessing antimicrobial resistances. The use of ultraviolet-C (UV-C) to sanitise mobile phones presents an alternative means to complement basic hand hygiene to prevent the cross-contamination and dissemination of microorganisms between hands and mobile phones. Aim. This study aimed to evaluate the germicidal efficacy of the Glissner CleanPhone UV-C phone sanitiser (Glissner) device. Methods. Two experimental trials were performed for the evaluation of the CleanPhone (Glissner). The first was a controlled trial, where the germicidal efficacy of the CleanPhone was evaluated against six different microorganism species that were inoculated onto mobile phones. The second was a field trial evaluating the germicidal efficacy of the CleanPhone on 100 volunteer mobile phones. Efficacy was determined based on colony counts of microorganisms on Columbia sheep blood agar before and after UV-C treatment. Results. In the controlled trial, reduction in growth was observed for all microorganisms after UV-C treatment with ST131 Escherichia coli showing the highest growth reduction at 4 log10 CFU/mL followed by C. albicans and ATCC E. coli at 3 log10 CFU/mL. An overall reduction in microorganism growth after UV-C treatment was also observed for the field trial, with an average growth reduction of 84.4% and 93.6% in colony counts at 24 h and 48 h post-incubation, respectively. Conclusion. The findings demonstrated the capability of the CleanPhone (Glissner) to rapidly sanitise mobile phones, thereby providing a means to reduce the potential dissemination of microorganisms, including highly pathogenic strains with antimicrobial resistance

Do mobile phone surfaces carry SARS-CoV-2 virus? A systematic review warranting the inclusion of a “6th” moment of hand hygiene in healthcare

Background Mobile phones, used in billions throughout the world, are high-touch devices subject to a dynamic contamination of microorganisms and rarely considered as a dynamic fomite to sanitise systematically. The emergence of SARS-CoV-2 resulted in the COVID-19 pandemic, arguably the most impactful pandemic of the 21st century with millions of deaths and disruption of all facets of modern life globally. Aim To perform a systematic review of the literature exploring SARS-CoV-2 presence as a contaminant on mobile phones. Methods A systematic search (PubMed and Google Scholar) of literature was undertaken from December 2019 to February 2023 identifying English language studies. Studies included in this review specifically identified or tested for the contamination of the SARS-CoV-2 virus or genome on mobile phones while studies SARS-CoV-2 testing for SARS-COV-2 in environments and/or other fomites samples than but not mobile phones were excluded. Results A total of 15 studies with reports of SARS-CoV-2 contamination on mobile phones between 2020-2023 were included. Amongst all studies, which encompassed ten countries, 511 mobile phones were evaluated for the presence of SARS-CoV-2 contamination and 45% (231/511) were positive for SARS-CoV-2. All studies were conducted in the hospital setting and two studies performed additional testing in residential isolation rooms and a patient’s house. Four studies (3 in 2020 and one in 2021) reported 0% contamination while two other studies (in 2020 and 2022) reported 100% of mobile phone contamination with SARS-COV-2. All other studies report mobile phones positive for the virus within a range of 4% to 77%. Conclusion A total of 45% of mobile phones are contaminated with SARS-CoV-2 virus. These devices might be an important fomite vector for viral dissemination worldwide. Competent health authorities are advised/recommended to start a global implementation of mobile phone decontamination by introducing regulations and protocols in public health and health care settings such as the 6th moment of hand washing
