Overview

Retrospective study reveals predictors of influenza vaccination in older adults, suggesting targeted strategies for improvement.

Key Points

  • This study aims to assess influenza vaccination uptake and the determinants influencing it in older adults.
  • Conducted a retrospective cross-sectional study among patients aged ≥65 years during the 2022-2023 influenza season.
  • Analyzed data from a unified electronic medical record system, including demographics, comorbidities, and vaccination status.
  • Utilized logistic regression to identify independent predictors of vaccine uptake.
  • Out of 302,815 eligible older adults, 160,929 (53.2%) received an influenza vaccine.
  • Prior-year vaccination was the strongest predictor of uptake (OR:30.1; 95% CI:29.5-30.7).
  • Spousal vaccination increased individual uptake significantly (OR:8.33; 95% CI:8.09-8.57).
