Abstract
Objective
To determine the percentage of parents in King County, Washington using an alternative childhood immunization schedule (ACIS) and the type of ACIS used.
Patient and Methods
We distributed self-administered surveys to parents at 5 practices regarding the immunization schedule they planned to use or were using. Parents who selected an ACIS were asked to describe its main characteristics and information source.
Results
We received 517 surveys and included 502 in analysis. The percentage of parents using an ACIS was 9.4% (95% CI: 7%, 12.2%). Only 6% described their ACIS as the Dr. Sears Schedule, although the book in which it is featured was the most frequently cited ACIS information source (29%). There was a significant association between ACIS use and non-Hispanic white parents and parents of children 12–23 months old.
Conclusion(s)
A minority of King County parents use an ACIS. The Dr. Sears Schedule does not predominate.
