Learning Objectives for this Presentation:
By the end of the presentation, participants will be able to appreciate the differences in up-to-date immunization rates when children receive all recommended immunizations at one, two, or three or more clinics.

Background:
California VFC Program Representatives conduct immunization chart reviews to determine the clinic's immunization rate during their Quality Assurance Review Site Visit. Up-to-date immunization rates are based on children ages 19-35 month, looking at the 4-3-1-3-3-1 (4 DTaP, 3 Polio, 1 MMR, 3 Hib, 3 Hep B and 1 Varicella) series. Los Angeles County VFC Representatives studied if children's up-to-date immunization rate in Los Angeles County differed if they received all immunizations at one, two or three or more clinics. Having been to only “one” clinic does not necessarily mean that it was that child's medical home.

Objectives:
To determine if children's up-to-date immunization rates differ when receiving immunizations in one, two, or three or more clinics.

Methods:
Utilizing California's Lot Quality Assurance (LQA) tally sheet, immunization records of children between ages of 19-35 months were surveyed. Data was collected using the tally sheet by recording how many clinics a child had visited to receive their immunizations. This survey began August 2005 and will continue through January 2006.

Results:
To date, 492 children were assessed. 275 visited only one clinic, 177 visited two and 40 visited three or more. Based on the criteria listed above, 243 (88%) who visited only one clinic were up-to-date, 135 (76%) who visited two clinics were up-to-date and 32 (80%) who visited three or more clinics were up-to-date.

Conclusions:
Based on current results, up-to-date immunization rates differed with children visiting only one clinic having the highest rates. Interestingly, children who visited three or more clinics had a higher up-to-date immunization rate than children who visited two clinics.
