Introduction From the onset of the COVID-19 pandemic, public health officials have sought to develop evidence-based messages to reduce COVID-19 transmission by communicating key information to media outlets and the public. We describe the development of an interdisciplinary rapid message testing model to quickly create, test, and share messages with public health officials for use in health campaigns and policy briefings. Methods An interdisciplinary research team from the University of North Carolina at Chapel Hill assembled in March 2020 to assist the state health department in developing evidence-based messages to influence social distancing behaviors in the state. We developed and iteratively executed a rapid message testing model; the components of the 4-step model were message creation, survey development, survey administration, and analysis and presentation to health department officials. The model was executed 4 times, each during a 7-day period in April and May, and each subsequent survey included new phrasing and/or messaging informed by the previous week’s survey. A total of 917 adults from North Carolina participated in the 4 surveys. Results Survey participants rated messages focused on protecting oneself and others higher than messages focused on norms and fear-based approaches. Pairing behaviors with motivations increased participants’ desire to social distance across all themes and subgroups. For example, adding “Protect your grandmother, your neighbor with cancer, and your best friend with asthma,” to messaging received a 0.9-point higher score than the base message, “Stay 6 feet apart from others when out in public.” Practice Implications Our model to promote social distancing in North Carolina during the COVID-19 pandemic can be used for rapid, iterative message testing during public health emergencies.

Background: "Decolonizing global health" (DGH) may help global health trainees understand and remediate the effects of historical colonialism on global health, but little is known regarding how trainees perceive DGH. Understanding their perspectives is critical for designing educational interventions tailored to their needs.Objectives: To understand how trainees perceive DGH research and to determine if perspectives differ between trainees from high-(HICs) versus low-and middle-income countries (LMICs).Methods: An online survey of all 2017-2022 pre-doctoral and post-doctoral trainees (n = 111) and mentors (n = 91) within a multi-university program that supports US and international investigators in one-year mentored global health research. The survey evaluated individuals' self-reported knowledge and attitudes toward DGH and their perceptions of historical colonialism's impact on eight aspects of global health. Findings:The response rate to trainee surveys was 56%. Trainees from LMICs were less aware of the concept of DGH; 5/25 (20%) had never heard of DGH and 16/25 (64%) reported that they "know a little," whereas all HIC trainees had heard of DGH and 29/36 (81%) reported that they "know a little" (p = 0.019). For three aspects of global health (i.e., which research questions get asked; development of collaborative relationships; and data/statistical analyses), trainees from LMICs were more likely to report positive effects of colonialism. However, in open-ended responses, no thematic differences existed between how LMIC and HIC trainees defined DGH (i.e., actively eliminating power imbalances; prioritizing local needs; promoting local leadership; providing equitable opportunities; and ensuring programs are culturally appropriate).

Introduction: In the early months of COVID-19 pandemic, a decline in stroke hospital admissions were reported nationwide. In a large, diverse region of Southern California, a collaborative effort was made to collect real-time data trends in stroke code activations and to assess this impact locally. The San Diego (SD) County Stroke Receiving Centers demonstrated a notable decrease of 30% in stroke code activations from March-May 2020 as compared to the same timeframe in 2019, which motivated the group to dedicate time and resources to pursue a united community messaging focused on seeking emergency treatment for stroke. Methods: A unified marketing campaign was created in collaboration with SD County EMS and the SD region American Heart Association/American Stroke Association. A single graphic message was utilized that emphasized the importance of seeking emergency treatment when suffering signs of stroke, along with the slogan “We are here for you. Every minute matters.” Impact of the campaign was gauged by quantifying the number of times our message was viewed on social media and number of stroke code activations after the campaign ended. Results: The unified social media campaign was posted by 14 of the 18 SD County stroke receiving hospitals during the month of June 2020. The team utilized Facebook, Twitter, Instagram and LinkedIn to convey the message. The campaign yielded a total of 26,727 views. The median monthly stroke code activations in July 2020 increased to 34, as compared to 26.5 for March-May 2020. Conclusion: In a time when social distancing has become the norm, it is more important than ever to band together as a community. This endeavor demonstrates that virtual messaging serves as a viable option for community education during the COVID-19 pandemic and in the future. A unified social messaging campaign targeting the importance of seeking emergency care for stroke during the COVID-19 pandemic is an effective way to reach large numbers of people regionally.
