COVID-19 Vaccine Hesitancy Among Clinical Health Care Workers (HCWs) in Four Major Healthcare Systems in Metro Atlanta Público
Farrque, Mirza (Spring 2022)
Abstract
Background: Since COVID-19 vaccines were approved for emergency use in late 2020, they
remain the most effective known preventive measure for fighting the current pandemic. Several
studies have highlighted COVID-19 vaccine hesitancy in the general population; however, little
is known about the nature and extent of COVID-19 vaccine hesitancy in healthcare workers
(HCWs) in Georgia. This current study assessed the prevalence and risk factors of COVID-19
vaccine hesitancy among clinical HCWs in four healthcare systems in metro Atlanta.
Method: The study included demographic and COVID-19 vaccination-related data collected
from clinical HCWs. Data was collected through an anonymous cross-sectional survey using
Qualtrics via email to all HCWs in May-June 2021. We estimated the prevalence of vaccine hesitancy
across clinical healthcare roles and assessed the predictors using a logistic regression
model. We also examined the perception and reasons for vaccine hesitancy among vaccine-hesitant
HCWs. All analyses were done in SAS 9.4 and statistical significance was assumed at a
0.05 level.
Results: A total of 3373 clinical HCWs were surveyed in this study with a response rate of
approximately 18%. Overall, 9.7% of clinical HCWs were vaccine-hesitant. Physicians were the
least vaccine-hesitant (1.8%), whereas paramedics (29.1%), medical/nursing assistants (14.6%),
nurses (13.4%), and technologists (13.4%) were the most vaccine-hesitant groups. About half of
the vaccine-hesitant clinical HCWs were nurses. Factors that were positively associated with
vaccine-hesitancy included young age, previous COVID-19 infection, and children under 18
years at home. Higher education, Asian race, Hispanic ethnicity, and having a family member
with critical COVID-19 were negatively associated with vaccine-hesitancy. Among all
respondents, 54% doubted its effectiveness, 30% were concerned about side effects, and 40% did
not agree to mandatory COVID-19 vaccination for HCWs. Among the vaccine-hesitant HCWs,
the top concerns were side effects (45%), limited knowledge (18%), and wanting more people to
get vaccinated (26%).
Conclusion: Vaccine hesitancy among clinical HCWs was highest among younger and less
educated HCWs. A considerable proportion of HCWs had negative perceptions of COVID-19
vaccines and documented less confidence in getting this. Therefore, targeted interventions such
as information leaflets, posters, or regular plenary presentations are needed to improve vaccine
uptake among HCWs.
