Modeling the Impact of Nonpharmaceutical Interventions on COVID-19 Transmission in K-12 Schools
Background. The novel coronavirus SARS-CoV-2 spread across the world causing many waves of COVID-19. Children were at high risk of being exposed to the disease because they were not eligible for vaccination during the first 20 mo of the pandemic in the United States. While children 5 y and older are now eligible to receive a COVID-19 vaccine in the United States, vaccination rates remain low despite most schools returning to in-person instruction. Nonpharmaceutical interventions (NPIs) are important for controlling the spread of COVID-19 in K-12 schools. US school districts used varied and layered mitigation strategies during the pandemic. The goal of this article is to analyze the impact of different NPIs on COVID-19 transmission within K-12 schools. Methods. We developed a deterministic stratified SEIR model that captures the role of social contacts between cohorts in disease transmission to estimate COVID-19 incidence under different NPIs including masks, random screening, contact reduction, school closures, and test-to-stay. We designed contact matrices to simulate the contact patterns between students and teachers within schools. We estimated the proportion of susceptible infected associated with each intervention over 1 semester under the Omicron variant. Results. We find that masks and reducing contacts can greatly reduce new infections among students. Weekly screening tests also have a positive impact on disease mitigation. While self-quarantining symptomatic infections and school closures are effective measures for decreasing semester-end infections, they increase absenteeism. Conclusion. The model provides a useful tool for evaluating the impact of a variety of NPIs on disease transmission in K-12 schools. While the model is tested under Omicron variant parameters in US K-12 schools, it can be adapted to study other populations under different disease settings.HighlightsA stratified SEIR model was developed that captures the role of social contacts in K-12 schools to estimate COVID-19 transmission under different nonpharmaceutical interventions.While masks, random screening, contact reduction, school closures, and test-to-stay are all beneficial interventions, masks and contact reduction resulted in the greatest reduction in new infections among students from the tested scenarios.Layered interventions provide more benefits than implementing interventions independently
Mind maps and network analysis to evaluate conceptualization of complex issues: A case example evaluating systems science workshops for childhood obesity prevention
Across disciplines, it is common practice to bring together groups to solve complex problems. Facilitators are often asked to help groups organize information about and better understand the problem in order to develop and prioritize solutions. However, despite existence of several methods to elicit and characterize how individuals and groups think about and conceptualize an issue, many are difficult to implement in practice-based settings where resources such as technology and participant time are limited and research questions shift over time. This paper describes an easy-to-implement diagramming technique for eliciting conceptualization and a flexible network analysis method for characterizing changes in both individual and group conceptualization. We use a case example to illustrate how we used the methods to evaluate African American adolescent's conceptual understanding of obesity before and after participating in a series of four systems thinking workshops. The methods produced results that were sensitive to changes in conceptualization that were likely driven by the specific activities employed during the workshop sessions. The methods appear strong for capturing salient levels of conceptualization at both individual and collective levels. The paper concludes with a critical examination of strengths and weaknesses of the methods and implications for future practice and research
Development of a Systems Science Curriculum to Engage Rural African American Teens in Understanding and Addressing Childhood Obesity Prevention
Engaging youth from racial and ethnic minority communities as leaders for change is a potential strategy to mobilize support for addressing childhood obesity, but there are limited curricula designed to help youth understand the complex influences on obesity. Our aim was to develop and pilot test a systems science curriculum to elicit rural African American youth perspectives on childhood obesity and enhance their understanding of and support for obesity prevention solutions. The curriculum was designed so it could be integrated with existing positive youth development curricula that help youth advocate for and implement identified solutions. We conducted four workshop sessions with youth that engaged them in systems learning activities such as guided systems diagramming activities. The participants (n = 21) completed validated surveys presession and postsession that assessed their causal attributions of obesity and support for obesity prevention policies. The youths’ perception that environmental factors cause obesity increased (p <.05), and perceptions that individual behavior and biology cause obesity did not change. Their support for policies that addressed food access and food pricing significantly increased (p <.05). The youths’ system diagrams elucidated links between multilevel factors such as personal attitudes, social influence, and the built environment, which provides important information for designing synergistic solutions. The changes we observed in youths’ perceptions of obesity and support for policy changes have important implications for youths’ interest and willingness to advocate for social and environmental changes in their community. The strategies have a promising role in supporting community mobilization to address childhood obesity
Stakeholder perspectives on addressing adverse events from adjuvant cancer therapy: A qualitative study
Background: With increasing survival rates, a growing population of patients with cancer have received or will receive adjuvant therapy to prevent cancer recurrences. Patients and caregivers will confront the complexities of balancing the preventative benefits of adjuvant therapy with possible near-term or long-term adverse events (AEs). Adjuvant treatment–related AEs (from minimal to severe) can impact therapeutic adherence, quality of life, emotional and physical health, and survival. However, to the authors' knowledge, limited information is available regarding how stakeholders use or desire to use adjuvant-related AE information to inform the care of patients with cancer. Methods: A qualitative, purposeful sampling approach was used to elicit stakeholder feedback via semistructured interviews (24 interviews). Drug development, drug regulatory, clinical, payer, and patient/patient advocacy stakeholders were questioned about the generation, dissemination, and use of adjuvant treatment–related AE information to inform the care of patients with cancer. Transcripts were coded independently by 2 senior health care researchers and reconciled to identify key themes. Results: All stakeholder groups in the current study identified needed improvements in each of the following 4 areas: 1) improving the accessibility and relevance of AE-related information; 2) better integrating and implementing available information regarding AEs for decisions; 3) connecting contemporary cultural and economic value systems to the generation and use of information regarding adjuvant treatment–related AEs; and 4) addressing a lack of alignment and ownership of stakeholder efforts to improve the use of AE information in the adjuvant setting. Conclusions: Despite commonalities in the overall needs identified by the diverse stakeholders in the current study, broad systemic change has been stymied. The current study identified the lack of alignment and the absence of a central “owner” of these diffuse efforts as a previously unrecognized hurdle to realizing the desired systemic improvements. Future initiatives aimed at improving quality of life and outcomes for patients receiving adjuvant therapy through the improved use of AE information must address this challenge through innovative collectives and novel leadership strategies
A qualitative analysis of Medicaid beneficiaries perceptions of prenatal and immediate postpartum contraception counseling
Objectives: In the United States, about four out of every ten births are financed by Medicaid, making it a program that is key in addressing racial disparities in maternal health. Many women covered by Medicaid have access to prenatal and immediate postpartum contraception counseling that can aid them in their postpartum contraception decision-making. However, existing inequities within Medicaid and a history of reproductive harms targeting Black women and women with low incomes may contribute to women with Medicaid having different experiences of contraception counseling. This qualitative study explores how Black women and White women insured by Medicaid perceive prenatal and immediate postpartum contraception counseling and identifies additional factors that shape their contraception decision-making. Methods: We conducted semi-structured interviews with 15 Medicaid beneficiaries who delivered at a public teaching hospital in North Carolina. Interviews focused on women?s beliefs about planning for pregnancy, experiences with prenatal and immediate postpartum contraception counseling, and perceived need for postpartum contraception. We used a priori and emergent codes to analyze interviews. Results: Seven Black women and eight White women completed interviews 14-60 days postpartum. All women reported receiving prenatal and immediate postpartum counseling. Several women described receiving prenatal counseling, reflective of patient-centered contraception counseling, that helped in their postpartum contraception decision-making; one woman described receiving immediate postpartum counseling that helped in her decision-making. Some Black women reported receiving unsupportive/coercive contraception counseling. In addition to contraception counseling, past reproductive health experiences and future pregnancy intentions were salient to women's contraception decision-making.Conclusions:Prenatal and immediate postpartum contraception counseling can help some Medicaid beneficiaries with their postpartum contraception decision, but past reproductive health experiences and future pregnancy intentions are also relevant. Counseling that does not consider these experiences may be harmful, particularly to Black women, further contributing to racial disparities in maternal postpartum health outcomes
Action Learning Cohort Series: An Innovative Community-Engaged Approach for Translating Research Into Practice
Cultivating strong partnerships among community and academic stakeholders expedites the translation of research findings into practice and communities by enhancing opportunities for research dissemination and implementation. However, the lack of systematic methods for community stakeholder engagement may decelerate the translational research process. The North Carolina Translational Research and Clinical Sciences Institute implemented an innovative approach to community engagement called the Action Learning Cohort (ALC) Series. The ALC Series, a workgroup extension of a professional conference, used action learning and systems thinking strategies to conceptualize and develop a product aimed at preventing, treating, and controlling hypertension in eastern North Carolina. We evaluated the acceptability and practicality of the ALC Series using survey, focus group, and interview pilot data. Action learning and systems thinking strategies led ALC stakeholders to develop and disseminate The Empathy Building Resource Guide: A Toolkit for Enhancing Patient–Provider Relationships in the Treatment, Management, and Prevention of Hypertension. Stakeholders rated the Series as satisfactory and acknowledged gains in knowledge and desire for engagement with fellow ALC stakeholders beyond the Series. The ALC Series approach is a potentially practical and acceptable model for systematically engaging community stakeholders in translating knowledge into a product that addresses health topics like hypertension
Does a transition to accountable care in Medicaid shift the modality of colorectal cancer testing?
Abstract
Background
Health care reform is changing preventive services delivery. This study explored trajectories in colorectal cancer (CRC) testing over a 5-year period that included implementation of 16 Medicaid Accountable Care Organizations (ACOs, 2012) and Medicaid expansion (2014) – two provisions of the Affordable Care Act (ACA) - within the state of Oregon, USA.
Methods
Retrospective analysis of Oregon’s Medicaid claims for enrollee’s eligible for CRC screening (50–64 years) spanning January 2010 through December 2014. Our analysis was conducted and refined April 2016 through June 2018. The analysis assessed the annual probability of patients receiving CRC testing and the modality used (e.g., colonoscopy, fecal testing) relative to a baseline year (2010). We hypothesized that CRC testing would increase following Medicaid ACO formation – called Coordinated Care Organizations (CCOs).
Results
A total of 132,424 unique Medicaid enrollees (representing 255,192 person-years) met inclusion criteria over the 5-year study. Controlling for demographic and regional factors, the predicted probability of CRC testing was significantly higher in 2014 (+ 1.4 percentage points, p < 0.001) compared to the 2010 baseline but not in 2012 or 2013. Increased fecal testing using Fecal Occult Blood Tests (FOBT) or Fecal Immunochemical Tests (FIT) played a prominent role in 2014. The uptick in statewide fecal testing appears driven primarily by a subset of CCOs.
Conclusions
Observed CRC testing did not immediately increase following the transition to CCOs in 2012. However increased testing in 2014, may reflect a delay in implementation of interventions to increase CRC screening and/or a strong desire by newly insured Medicaid CCO members to receive preventive care
Cross-sector decision landscape in response to COVID-19: A qualitative network mapping analysis of North Carolina decision-makers
Introduction The COVID-19 pandemic response has demonstrated the interconnectedness of individuals, organizations, and other entities jointly contributing to the production of community health. This response has involved stakeholders from numerous sectors who have been faced with new decisions, objectives, and constraints. We examined the cross-sector organizational decision landscape that formed in response to the COVID-19 pandemic in North Carolina. Methods We conducted virtual semi-structured interviews with 44 organizational decision-makers representing nine sectors in North Carolina between October 2020 and January 2021 to understand the decision-making landscape within the first year of the COVID-19 pandemic. In line with a complexity/systems thinking lens, we defined the decision landscape as including decision-maker roles, key decisions, and interrelationships involved in producing community health. We used network mapping and conventional content analysis to analyze transcribed interviews, identifying relationships between stakeholders and synthesizing key themes. Results Decision-maker roles were characterized by underlying tensions between balancing organizational mission with employee/community health and navigating organizational vs. individual responsibility for reducing transmission. Decision-makers' roles informed their perspectives and goals, which influenced decision outcomes. Key decisions fell into several broad categories, including how to translate public health guidance into practice; when to institute, and subsequently loosen, public health restrictions; and how to address downstream social and economic impacts of public health restrictions. Lastly, given limited and changing information, as well as limited resources and expertise, the COVID-19 response required cross-sector collaboration, which was commonly coordinated by local health departments who had the most connections of all organization types in the resulting network map. Conclusions By documenting the local, cross-sector decision landscape that formed in response to COVID-19, we illuminate the impacts different organizations may have on information/misinformation, prevention behaviors, and, ultimately, health. Public health researchers and practitioners must understand, and work within, this complex decision landscape when responding to COVID-19 and future community health challenges
Endocrine therapy initiation among Medicaid-insured breast cancer survivors with hormone receptor-positive tumors
Hormone receptor positive (HR+) cancers account for most breast cancer diagnoses and deaths. Among survivors with HR+ breast cancers, endocrine therapy (ET) reduces 5-year risk of recurrence by up to 40%. Observational studies in Medicare and privately-insured survivors suggest under-utilization of ET. We sought to characterize ET use in a low-income Medicaid-insured population in North Carolina
The Burden of COVID-19 on Caregivers of Children with Suspected Genetic Conditions: A Therapeutic Odyssey
Aims: Children with disabilities and rare or undiagnosed conditions and their families have faced numerous hardships of living during the COVID-19 pandemic. For those with undiagnosed conditions, the diagnostic odyssey can be long, expensive, and marked by uncertainty. We, therefore, sought to understand whether and how COVID-19 impacted the trajectory of children’s care. Methods: We conducted semi-structured qualitative interviews with 25 caregivers who, prior to the pandemic, were on a diagnostic odyssey for their children. Results: Most caregivers did not report any interruptions to their child’s diagnostic odyssey. The greatest impact was access to therapy services, including the suspension or loss of their child’s in-person therapeutic care and difficulties with virtual therapies. This therapy gap caused caregivers to fear that their children were not making progress. Conclusion: Although much has been written about the challenges of diagnostic odysseys for children and their families, this study illustrates the importance of expanding the focus of these studies to include therapeutic odysseys. Because therapeutic odysseys continue regardless of whether diagnoses are made, future research should investigate how to support caregivers through children’s therapies within and outside of the COVID-19 context
