title: Practice and child characteristics associated with influenza vaccine uptake in young children.
abstract: OBJECTIVE
  The objective of this study was to determine both practice and child characteristics and practice strategies associated with receipt of influenza vaccine in young children during the 2004-2005 influenza season, the first season for the universal influenza vaccination recommendation for all children who are aged 6 to 23 months.
  
  
  METHODS
  Clinical and demographic data from randomly selected children who were aged 6 to 23 months were obtained by chart review from a community-based cohort study in 3 US counties. The proportion of children who were vaccinated by April 5, 2005, in each practice was obtained. For assessment of practice characteristics and strategies, sampled practices received a self-administered practice survey. Practice and child characteristics that predicted complete influenza vaccination were determined by using multinomial logistic regression.
  
  
  RESULTS
  Forty-six (88%) of 52 sampled practices completed the survey and permitted chart reviews. Of 2384 children who were aged 6 to 23 months and were studied, 27% were completely vaccinated. The proportion of children who were completely vaccinated varied widely among practices (0%-71%). Most (87%) practices implemented ≥1 vaccination strategy. Complete influenza vaccination was associated with 3 practice characteristics: suburban location, lower patient volume, and vaccination strategies of evening/weekend vaccine clinics; with child characteristics of younger age, existing high-risk conditions, ≥6 well visits to the practice by 3 years of age, and any practice visit from October through January.
  
  
  CONCLUSIONS
  Modifiable factors that were associated with increased influenza vaccination coverage included October to January practice visits and evening/weekend vaccine clinics.
