Impact of State Stroke Systems of Care Laws on Stroke Outcomes.

Since 2003, 38 US states and Washington, DC have adopted legislation and/or regulations to strengthen stroke systems of care (SSOCs). This study estimated the impact of SSOC laws on stroke outcomes. We used a coded legal dataset of 50 states and DC SSOC laws (years 2003-2018), national stroke accreditation information (years 1997-2018), data from the Healthcare Cost and Utilization Project (years 2012-2018), and National Vital Statistics System (years 1979-2019). We applied a natural experimental design paired with longitudinal modeling to estimate the impact of having one or more SSOC policies in effect on outcomes. On average, states with one or more SSOC policies in effect achieved better access to primary stroke centers (PSCs) than expected without SSOC policies (ranging from 2.7 to 8.0 percentage points (PP) higher), lower inpatient hospital costs (USD 610-1724 less per hospital stay), lower age-adjusted stroke mortality (1.0-1.6 fewer annual deaths per 100,000), a higher proportion of stroke patients with brain imaging results within 45 min of emergency department arrival (3.6-5.0 PP higher), and, in some states, lower in-hospital stroke mortality (5 fewer deaths per 1000). Findings were mixed for some outcomes and there was limited evidence of model fit for others. No effect was observed in racial and/or rural disparities in stroke mortality.

Reflections From School Communities in Underserved Populations on Childhood COVID-19 Vaccination.

OBJECTIVES: Outbreaks in vaccine-preventable diseases among children have increased, primarily among under- or unvaccinated subgroups. The influence and interaction of a child's school community on parental health care decisions, such as vaccination, has not been explored. Our study examined childhood coronavirus disease 2019 (COVID-19) vaccine hesitancy within the context of school communities. METHODS: This study combines data from 4 independent research studies funded by the National Institutes of Health Rapid Acceleration of Diagnostics Underserved Populations Return to School Initiative. We examined focus group data to better understand the apprehension surrounding parental and child COVID-19 vaccination among underserved school populations. RESULTS: Across all study sites, 7 main themes emerged with regard to COVID-19-related vaccination concerns for children: (1) potential side effects, (2) vaccine development, (3) misinformation (subthemes: content of vaccine and negative intent of the vaccine), (4) vaccine effectiveness, (5) timing of vaccine administration/availability for children, (6) fear of needles, and (7) mistrust. CONCLUSIONS: School settings offered unique access to youth and family perspectives in underserved communities. Our studies highlighted several factors contributing to COVID-19 vaccine hesitancy in school communities, which align with existing literature on vaccine hesitancy. These concerns centered primarily on potential harm of vaccines, as well as misinformation, mistrust, and timing of vaccines. Related recommendations for increasing vaccination rates are provided. Developing specific strategies that address parent and child concerns will be critical to reducing health inequities related to COVID-19 vaccination.

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.

Utilization and Impact of Symptomatic and Exposure SARS-CoV-2 Testing in K-12 Schools.

OBJECTIVES: The Centers for Disease Control and Prevention recommend that schools can offer severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) diagnostic (on-demand) testing for students and staff with coronavirus disease 2019 symptoms or exposures. Data related to the uptake, implementation, and effect of school-associated on-demand diagnostic testing have not been described. METHODS: The Rapid Acceleration of Diagnostics Underserved Populations Return to School program provided resources to researchers to implement on-demand SARS-CoV-2 testing in schools. This study describes the strategies used and uptake among the different testing programs. Risk of positivity was compared for symptomatic and exposure testing during the δ and ο variant periods. We estimated the number of school absence days saved with school-based diagnostic testing. RESULTS: Of the 16 eligible programs, 7 provided school-based on-demand testing. The number of persons that participated in these testing programs is 8281, with 4134 (49.9%) receiving >1 test during the school year. Risk of positivity was higher for symptomatic testing compared with exposure testing and higher during the ο variant predominant period compared with the δ variant predominant period. Overall, access to testing saved an estimated 13 806 absent school days. CONCLUSIONS: School-based on-demand SARS-CoV-2 testing was used throughout the school year, and nearly half the participants accessed testing on more than 1 occasion. Future studies should work to understand participant preferences around school-based testing and how these strategies can be used both during and outside of pandemics.

SARS-CoV-2 Screening Testing Programs for Safe In-person Learning in K-12 Schools.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) screening testing is a recommended mitigation strategy for schools, although few descriptions of program implementation are available. METHODS: Kindergarten through 12th grade (K-12) students and staff practicing universal masking during the delta and omicron variant waves from five schools in Durham, North Carolina and eight schools in Kansas City, Missouri participated; Durham's program was structured as a public health initiative facilitated by school staff, and Kansas City's as a research study facilitated by a research team. Tests included school-based rapid antigen or polymerase chain reaction testing, at-home rapid antigen testing, and off-site nucleic acid amplification testing. RESULTS: We performed nearly 5700 screening tests on more than 1600 K-12 school students and staff members. The total cost for the Durham testing program in 5 public charter K-12 schools, each with 500-1000 students, was $246 587 and approximately 752 h per semester; cost per test was $70 and cost per positive result was $7076. The total cost for the Kansas City program in eight public K-12 schools was $292 591 and required approximately 537 h in personnel time for school-based testing; cost per test was $132 and cost per positive result was $4818. SARS-CoV-2 positivity rates were generally lower (0-16.16%) than rates in the community (2.7-36.47%) throughout all testing weeks. CONCLUSIONS AND RELEVANCE: Voluntary screening testing programs in K-12 schools are costly and rarely detect asymptomatic positive persons, particularly in universally masked settings.
