Social Determinants of Health and Satisfaction With Sources of Information About COVID-19 Related to Vaccine Uptake in a Safety Net Healthcare System.

Background: Vaccination is a critical tool to combat the COVID-19 pandemic. Yet, vaccine uptake varies across communities and is often affected by sociodemographic factors and accessibility. Objectives: This article outlines a pilot study aimed to examine factors associated with COVID-19 patients within one of the nation's largest safety net healthcare systems. Methods: A cross-sectional survey design was conducted with adults over 18 years of age eligible to receive the COVID-19 vaccine. Descriptive analysis of survey data collected in 2021--2022 was employed. Unconditional and multivariate logistic regression analyses were conducted to examine associations between sociodemographics, social factors, and COVID-19 vaccine uptake. Results: Study participants (N = 280) were a diverse patient population, primarily low-income andmajority Hispanic/Latinx, with low education levels, but with a high level of COVID-19 vaccine uptake and a high rate of intent to vaccinate again. Approximately 22% report having unstable housing, and 46% experiencing food insecurity. Most trusted sources for COVID-19 data included mainstream media, including TV, radio, and newspapers, and friends, family, or other informal networks. We found that respondents who were satisfied or very satisfied with COVID-19 information received fromhealthcare providers or the government had higher odds of vaccine uptake rates. Discussion: These findings highlight the critical role of access to the COVID-19 vaccine and sources of information as an independent factor in COVID-19 vaccine uptake among patients within a safety net healthcare system. This study expands the literature on COVID-19 vaccine uptake, particularly in an underresourced region of the South Los Angeles community. Future research is needed to better understand the mechanisms between social determinants of health, perceived discrimination, and vaccine uptake. [ABSTRACT FROM AUTHOR]
