Evaluation of a COVID-19 Rapid Antigen Testing Program in a Supervised Community Distance Learning Setting for K-8 Students

Impact and cost-effectiveness of SARS-CoV-2 self-testing strategies in schools: a multicountry modelling analysis

OBJECTIVES

To determine the most epidemiologically effective and cost-effective school-based SARS-CoV-2 antigen-detection rapid diagnostic test (Ag-RDT) self-testing strategies among teachers and students.

DESIGN

Mathematical modelling and economic evaluation.

SETTING AND PARTICIPANTS

Simulated school and community populations were parameterised to Brazil, Georgia and Zambia, with SARS-CoV-2 self-testing strategies targeted to teachers and students in primary and secondary schools under varying epidemic conditions.

INTERVENTIONS

SARS-CoV-2 Ag-RDT self-testing strategies for only teachers or teachers and students-only symptomatically or symptomatically and asymptomatically at 5%, 10%, 40% or 100% of schools at varying frequencies.

OUTCOME MEASURES

Outcomes were assessed in terms of total infections and symptomatic days among teachers and students, as well as total infections and deaths within the community under the intervention compared with baseline. The incremental cost-effectiveness ratios (ICERs) were calculated for infections prevented among teachers and students.

RESULTS

With respect to both the reduction in infections and total cost, symptomatic testing of all teachers and students appears to be the most cost-effective strategy. Symptomatic testing can prevent up to 69·3%, 64·5% and 75·5% of school infections in Brazil, Georgia and Zambia, respectively, depending on the epidemic conditions, with additional reductions in community infections. ICERs for symptomatic testing range from US$2 to US$19 per additional school infection averted as compared with symptomatic testing of teachers alone.

CONCLUSIONS

Symptomatic testing of teachers and students has the potential to cost-effectively reduce a substantial number of school and community infections.

Facilitators and barriers to use rapid antigen test for SARS-CoV-2 among community-dwelling older adults in Hong Kong: A population-based cross-sectional random telephone survey

Faster diagnosis of Coronavirus disease 2019 (COVID-19) is crucial for surveillance, prompt implementation of infection control measures and adequate patient care among older adults. This study investigated the behavioral intention to use Rapid Antigen Tests (RAT) and associated factors among older adults in Hong Kong for health monitoring and when having COVID-19-like symptoms. This was a population-based cross-sectional random telephone survey of 370 Chinese-speaking adults aged ≥65 years. The behavioral intention to use RAT was the main outcome, and logistic regression models were used to assess the associated factors, using SPSS (version 26.0.). Results indicate that among the participants, 90.3% had used RAT, of which 21.6% obtained positive results. The common challenges faced when using RAT included: difficulty choosing the right RAT kit, uncertainty about how to use RAT, and not knowing what to do after getting a positive result. Additionally, 27.3% intended to use RAT regularly for health status monitoring without any symptoms, while 87.0% if they had COVID-19-like symptoms. After adjustment for significant background characteristics, positive attitudes, perceiving Hong Kong government and their children and/or other family members would support them using RAT, belief that RAT health promotion materials were helpful to understand how to use RAT and thoughtful consideration of the veracity of COVID-19 specific information were associated with higher behavioral intention to use RAT both when having no symptoms and in presence of COVID-19-like symptoms. Having negative attitudes toward RAT was associated with a lower intention of RAT use only when having no symptoms. Addressing difficulties faced when using RAT, strengthening positive attitudes, involving significant others and empowering with adequate information-veracity evaluating skills are potentially vital strategies to increase RAT use among older adults.

Multilevel perspectives on school-based opportunities to improve HPV vaccination among medically underserved adolescents: Beyond school entry mandates

School-based HPV vaccination programs have improved vaccine uptake among adolescents globally. However, school-based HPV vaccination strategies in the United States (US) have mainly focused on school-entry mandates for vaccination, which have passed in only five states/jurisdictions. Many schools and school-based health centers (SBHCs) already provide health services to medically underserved adolescents and opportunities to improve disparities in HPV vaccine education and uptake are underexplored. This qualitative study of clinic and community members assessed potential opportunities within and outside schools to increase HPV vaccination. Data were generated from a larger mixed-methods study designed to understand experiences with HPV vaccination evidence-based strategies in medically underserved communities. The parent study included interviews and focus groups conducted with clinic (providers, clinic leaders, staff) and community (racial/ethnic minority parents, advocates, payers, policy representatives) members in Los Angeles and New Jersey between December 2020-January 2022. We created a reduced dataset of text related to schools/SBHCs (30 in-depth interviews, 7 focus groups) and conducted a directed content analysis. Participants indicated that schools and SBHCs are ideal venues for reaching medically underserved adolescents experiencing barriers to primary care access. Parents/providers expressed mutual interest in HPV vaccine administration/education in schools, but some advocates/policy participants experienced challenges due to increasing politicization of vaccines. Participants highlighted policies for expanding HPV vaccine education and administration in schools, including minor consent and increasing SBHC funding for HPV vaccines. More research is needed to explore existing infrastructure, partner motivation, and opportunities to improve HPV vaccination among medically underserved adolescents within schools beyond vaccine mandates.

A Multi-Study Synthesis of Facilitators and Barriers to SARS-CoV-2 Testing Enrollment in School Settings

OBJECTIVES

Understanding the motivators and barriers to testing enrollment from different stakeholder perspectives is essential to increasing participation in school-based testing programs, particularly among underserved populations. This multistudy analysis aimed to identify facilitators and barriers to enrollment in school-based testing for coronavirus disease 2019 (COVID-19).

METHODS

Four independent studies collected and analyzed qualitative data from study participants regarding: (1) motivators, benefits, and/or reasons for enrolling and/or participating in COVID-19 testing in schools; and/or (2) concerns, barriers, and/or negative outcomes related to COVID-19 testing in schools. Study authors conducted a retrospective review of findings from the independent studies to identify themes related to testing motivators and concerns that emerged across the studies.

RESULTS

The analysis identified 10 distinct themes regarding the perceived motivators of COVID-19 testing in schools and 15 distinct themes regarding concerns and barriers to COVID-19 testing in schools. Common motivators across multiple studies included convenience of testing in school and the desire to keep self and others safe from COVID-19. Concerns about the implications of receiving a positive test result was a barrier identified by multiple studies.

CONCLUSIONS

Themes from 4 independent studies revealed insights about the motivations and barriers to enrolling and participating in COVID-19 testing programs in kindergarten through 12th grade school settings. Study findings can be used to improve enrollment and participation in new and existing school-based testing programs to reduce transmission of COVID-19 and other infectious diseases in schools.

Evaluation of a COVID-19 rapid antigen testing program among student athletes in a public high school district

PURPOSE

The purpose of this study is to evaluate a COVID-19 rapid antigen testing program among high school athletes through testing data and qualitative analysis from key stakeholders.

METHODS

Testing data was obtained by the partnering school district. Testing staff, coaches, and parents participated in a focus group using a semi-structured focus group guide. Transcripts were analyzed using a grounded theory approach to produce the themes of the study.

RESULTS

Rapid antigen tests quickly identified a COVID-19-positive student athlete, which allowed for quick isolation and zero transmission to teammates. Focus groups with parents, testing staff, and coaches indicated the testing program improved perceived safety and demonstrated the ability for school staff to implement a widespread COVID-19 screening program with minimal training.

CONCLUSIONS

As schools continue to respond to various waves of COVID-19 infections, targeted testing for high-risk activities in school settings such as sports programs may help prevent school outbreaks during times of high community transmission rates. This evaluation adds to a body of literature that will aid schools and policy makers in their decision on how to best keep student athletes and school communities safe for future waves of COVID-19 infection and other pandemics.
