AbstractBACKGROUND: Serial testing for SARS-CoV-2 is recommended to reduce spread of the virus; however, little is known about adherence to recommended testing schedules and reporting practices to health departments. OBJECTIVE: The Self-Testing for Our Protection from COVID-19 (STOP COVID-19) study aims to examine adherence to a risk-based COVID-19 testing strategy using rapid antigen tests and reporting of test results to health departments. METHODS: STOP COVID-19 is a 12-week digital study, facilitated using a smartphone app for testing assistance and reporting. We are recruiting 20,000 participants throughout the United States. Participants are stratified into high- and low-risk groups based on history of COVID-19 infection and vaccination status. High-risk participants are instructed to perform twice-weekly testing for COVID-19 using rapid antigen tests, while low-risk participants test only in the case of symptoms or exposure to COVID-19. All participants complete COVID-19 surveillance surveys, and rapid antigen results are recorded within the smartphone app. Primary outcomes include participant adherence to a risk-based serial testing protocol and percentage of rapid tests reported to health departments. RESULTS: As of February 2022, 3496 participants have enrolled, including 1083 high-risk participants. Out of 13,730 tests completed, participants have reported 13,480 (98.18%, 95% CI 97.9%-98.4%) results to state public health departments with full personal identifying information or anonymously. Among 622 high-risk participants who finished the study period, 35.9% showed high adherence to the study testing protocol. Participants with high adherence reported a higher percentage of test results to the state health department with full identifying information than those in the moderate- or low-adherence groups (high: 71.7%, 95% CI 70.3%-73.1%; moderate: 68.3%, 95% CI 66.0%-70.5%; low: 63.1%, 59.5%-66.6%). CONCLUSIONS: Preliminary results from the STOP COVID-19 study provide important insights into rapid antigen test reporting and usage, and can thus inform the use of rapid testing interventions for COVID-19 surveillance.

Policy Brief: Addressing Social Determinants of Health through Community Health Workers: A Call to ActionLondon, Katharine; Damio, Grace; Ferrazo, Meredith; Perez-Escamalla, Rafael; Wiggins, Noelle (2018-01-30)This technical report was compiled by the Hispanic Health Council in partnership with Southwestern AHEC and a panel of Community Health Worker Policy Research Experts which included our Katharine London from the Center for Health Law and Economics. The report offers a number of policy recommendations for community health workers for communities that might benefit from community-based services. The report offers recommendations on; payment of community health workers; community health worker caseloads; community health worker recruitment; community health worker training; reflective and trauma-informed mentoring and supportive supervision of community health workers; integration of community health workers into care teams; documenting the effect of community heal worker services on social determination of health. The Hispanic Health Council believes a service design that effectively supports community health workers would incorporate the seven areas of policy recommendation included in this report.
A Public Health Framework for the State Mental Health Authority: A Call for Action by Massachusetts Consumers and Family MembersDelman, Jonathan (2006-01-01)During the Spring of 2006, Consumer Quality Initiatives (CQI) conducted 20 focus groups across the state, 12 with adults with mental illness, 3 with parents of youth with serious emotional disorder, 2 with youth with SED, 1 with family members of adult consumers, and 2 with youth in transition. Supported by a contract with Massachusetts Department of Mental Health (DMH), the goal was to assist DMH in framing the criteria for its upcoming reprocurement. Our findings reveal a frustration with an approach to health care delivery that focuses primarily on the provision of psychiatric care (egs, medication, therapy, hospitalization). We reviewed the focus group reports to identify the most significant themes, which clustered within eight broad categories.
Making the Case for Sustainable Funding for Community Health Worker Services: Talking to Payers and ProvidersLondon, Katharine (2018-01-27)In this presentation, Katharine London of the Center for Health Law and Economics makes her case for offering sustainable funding for community health worker services. Research has shown community health workers can have a distinct impact on health systems, helping them improve population health and contain costs, while also promoting health equity and community engagement. This presentation was designed to assist CHWs and other advocates in engaging with policymakers and payers to support CHW sustainability and develop a financial plan for their CHW work. It was presented as part of a CHW Sustainability event held at the Families USA’s annual conference, Health Action 2018: Staying Strong for America’s Families, in Washington, DC.
