COVID19 -- Health Communication and Structural Intervention Evaluation -- K-VAC: Kentucky Vaccinating All Communities
The purpose of this community-engaged study is to test the ability of county-level strategies to increase uptake of COVID-19 vaccination. In this study the key objective is to test whether health communication strategies or health communication + county-specific structural/environmental support increases COVID-19 vaccine uptake and changes perceptions and beliefs about the vaccination at the county-level.
The intervention trial will be a community-based, three-arm cluster randomized controlled trial. The three arms are: (1) multilevel invention (vaccine communication campaign + community-level structural intervention),(2) health communications only intervention, and (3) control/standard of care. Randomization will take place at the county level. The 15 participating counties will first be matched into blocks of three, with each block being matched as closely as possible on recent county influenza vaccination rates. After matching, the three counties within each matched block will be randomly assigned to one of the three study arms. This technique of randomizing to study arm within each matched block of counties increases confidence that community-level factors that might influence vaccine uptake are equally distributed across study arms. Following randomization, the intervention process will begin in counties in the multilevel and communication campaign intervention arms. Assessment of primary and secondary study outcomes will take place 6 months after initiation of the intervention. Finally, after assessment of outcomes is complete, the intervention components will be offered to the control counties.
Up to 2,250 participants will take part in the study --- approximately 150 residents in each of the 15 participating Appalachian Kentucky Counties. In each of the fifteen counties, the investigators will collect survey data from 150 adults who are served by Homeplace, a medical and social services organization run by the UK Center for Excellence in Rural Health, which provides services in each of the 15 partner counties. Homeplace provides services to adults who are medically underserved and typically at 100-133% of the federal poverty level, primarily through service delivery by trained local Community Health Workers (CHWs). CHWs will recruit participants and collect the survey data from the identified individuals. Importantly, the criteria for qualification for Homeplace services are equivalent across the 15 counties, providing equivalence of sample across counties. A random sample of 150 individuals per county will be drawn from the Homeplace client database for that county. Gender, ethnic background, and health status will roughly mirror that of the demographics of the county.
