Associations Between Structural And Social Determinants Of Health With Covid Infection Rates At A Safety Net Hospital

Background: The reported disproportionate impact of COVID-19 infections on minority populations may be due to living in disinvested communities with a high level of poverty, pollution, inadequate unsafe employment, and overcrowded housing.Objective: To determine the association of county, city, and individual risk factors with COVID-19 infection rates.Methods: Retrospective chart review on COVID-19 tests performed from March through July 2020 at Arrowhead Regional Medical Center (ARMC), Colton, California.Results: A total of 7104 tests were performed with 69% in the drive-through testing center. The mean duration of test-to-results time was 2.36 (+0.02) days. COVID-19 positive tests occurred in 1095 (15.4%). At least one symptom occurred in 414 (33%) with a sensitivity of 37.8, specificity of 86.02, a positive predictive value of 33.01, and a negative predictive value of 72.76. Individual factors significantly associated with testing positive for COVID-19 were diabetes, Hispanic ethnicity, and male gender. Younger age was significantly associated with testing COVID positive with the highest risk in children <10 years.COVID-19 positive persons significantly resided in cities with higher population density, household members, poverty, non-English speaking homes, disability, lower median household income, lack of health insurance and decreased access to a computer and Wi-Fi services. County health rankings showed a significant positive association between testing positive for COVID-19 with increased smoking, air pollution, violent crimes, physical inactivity, decreased education, and access to exercise.Conclusion: Adverse county health rankings, socially and economically disadvantaged cities are associated with an increased risk of testing positive for COVD-19.
