Predictors of willingness to receive updated 2023-2024 COVID-19 booster vaccines among a convenience sample in Minnesota.

OBJECTIVES: To determine factors associated with intention to receive recommended COVID-19 booster vaccines in 2023-2024. METHODS: A cross-sectional study of 1,256 individuals at Minnesota State and County fairs was conducted to assess their intention to receive a COVID-19 booster vaccine in the coming year if recommended. The association between booster intention and multiple factors believed to influence willingness to receive the vaccine, including perceived vaccine safety, perceived risk of COVID-19, public health knowledge, fear of future pandemics, and political affiliation, were analyzed using ordinal logistic regression and adjusted odds ratios (aOR). RESULTS: Intention to receive a COVID-19 booster vaccine was high among our participants with 56% reporting they were extremely likely to receive the vaccine this year and another 15% reporting that they were likely to do the same. A strong association with getting a booster vaccine was found between perceived vaccine safety (aOR: 15.3, 95% CI: 10.6-22.2), perceived COVID-19 risk (aOR: 3.5, 95% CI: 2.4-5.1), pandemic fear (aOR: 3.4, 95% CI: 2.4-4.8), public health knowledge (aOR: 1.3, 95% CI: 0.9-1.8), and democrat political affiliation (aOR: 2.8, 95%CI: 1.8-4.4). CONCLUSIONS: Our study emphasizes the importance of perceived vaccine safety as a predictor of intention to accept COVID-19 vaccines and highlights the continued need to effectively communicate with the public about the safety of vaccines.

Improved Time to Notification of Impending Brain Death and Increased Organ Donation Using an Electronic Clinical Decision Support System.

Early referral of patients to an organ procurement organization (OPO) may positively affect donation outcomes. We implemented an electronic clinic decision support (CDS) system to automatically notify our OPO of children meeting clinical triggers indicating impending brain death. Medical records of all patients who died in a pediatric critical care unit or were referred for imminent death for 3 years prior to installation of the initial CDS (pre-CDS) and for 1 year after implementation of the final CDS (post-CDS) were reviewed. Mean time to OPO notification decreased from 30.2 h pre-CDS to 1.7 h post-CDS (p = 0.015). Notification within 1 h of meeting criteria increased from 36% pre-CDS to 70% post-CDS (p = 0.003). Although an increase in donor conversion from 50% pre-CDS to 90% post-CDS did not reach statistical significance (p = 0.0743), there were more organ donors post-CDS (11 of 24 deaths) than pre-CDS (seven of 57 deaths; p = 0.002). Positive outcomes were achieved with the use of a fully automated CDS system while simultaneously realizing few false-positive notifications, low costs, and minimal workflow interruption. Use of an electronic CDS system in a pediatric hospital setting improved timely OPO notification and was associated with increased organ donation.
