Factors Influencing Influenza and COVID-19 Vaccine Decision-Making in the Post-ICU Period: A Secondary Analysis.

backgroundThe introduction of COVID-19 vaccines exposed volatility and hesitancy around vaccines. Some health care models, including ICU recovery clinics (ICU-RCs), are structured to provide vaccine counseling. However, information regarding provider and patient vaccine conversations is limited in this postacute setting. RESEARCH QUESTION: What factors influence the decision-making process of patients who have survived an ICU stay surrounding influenza and COVID-19 vaccination? STUDY DESIGN AND

methodsTo understand further vaccine perceptions after critical illness, a secondary qualitative thematic analysis was performed using transcripts from a randomized controlled trial designed to develop and refine a telemedicine approach to ICU recovery. Thirty-three ICU-RC visits with 19 adult patients and 13 caregivers were conducted within 12 weeks of hospital discharge. The analysis was guided by the theory of planned behavior (TPB).

resultsFive themes were elicited from the data. The first four themes arose from the TPB: (1) behavioral and attitudinal beliefs (not being susceptible to the flu, concerns about the COVID-19 vaccine causing fertility issues, and not being tested enough), (2) normative beliefs (everyone they know is getting the influenza vaccine so they are, too), (3) control vaccine beliefs (patients are more likely to get the COVID-19 vaccine if it is easy to obtain), and (4) intention to vaccinate. Another theme not related to the TPB arose and could contribute to vaccine intent and behavior: (5) health team engagement with patients and caregivers (allowing for ICU clinicians to correct vaccine misinformation in real time).

interpretationUsing the information learned in our study, the period after critical illness or other acute illness events may be an especially fruitful target for designing an action plan for improving public trust in vaccines and improving overall completion rates; however, further research is needed.
