Effectiveness of Information Sessions About COVID-19 Vaccines in Healthcare Professionals Working in Geriatrics

Objectives: To determine change in (a) perceived knowledge about COVID-19 vaccines; (b) level of confidence in transmitting information about vaccines; and (c) intention to get vaccinated; among healthcare professionals (HCP) working in a Swiss academic geriatric department who attended a 30-minute information session about COVID-19 vaccines. Measurements: At the session’s end, a self-administered questionnaire collected information about socio-demographics, personnel, and/or relatives’ experience with COVID-19. In addition, participants were asked to rate their: (a) perceived knowledge about COVID-19 vaccines; (b) level of confidence in transmitting information about COVID-19 vaccines to patients and relatives; and (c) intention to get vaccinated; before and after the session. Results: Overall, 97 (42.2% of all HCPs) participated to 14 sessions and completed the questionnaire. Improvements were observed in knowledge, confidence in providing information, and intention to be vaccinated after the session (all p < .001). Similar improvements were observed in subgroup analyses by gender, age groups, profession (involved in direct care or not), and previous experience with COVID-19 (all p < .010). However, HCP aged 20 to 29 years were less likely to feel completely confident in providing information than those aged 30 to 49 and 50+ years (17.1% vs. 43.2% vs. 44.0%, respectively, p = .031) and to report being very likely to be vaccinated (31.4% vs. 56.8% vs. 56.0%, respectively, p = .060). Conclusions: These information sessions positively influenced HCP knowledge, confidence in providing information, and, to a lesser extent, intention to be vaccinated. Younger HCP reported similar improvements but remained less likely to consider vaccination. Additional efforts are needed to convince these undecided HCP and enhance COVID-19 vaccines uptake.
