The Health Index Initiative tracks and monitors a variety of data sources to measure progress being made to increase childhood immunizations. In 2016, MaineHealth leaders set bold, aggressive targets for two of these measures as a way to challenge MaineHealth organizations to continue achieving positive steps toward the MaineHealth vision.
Short-term immunization measure and target:
- Among 2-year-olds cared for by MaineHealth member owned family medicine and pediatric practices, 60% or more will be up-to-date on all ten vaccines recommended by the U.S. Centers for Disease Control and Prevention.
Long-term immunization measure and target:
- In three of the six years from 2015-2020, 80% or more of 19 to 35 month olds in Maine will be up-to-date for the bundle of 7 vaccines.
The U.S. Centers for Disease Control and Prevention (CDC) currently recommends 10 immunizations be fully administered to all children by age 2. To be considered up-to-date for all 10 vaccines, a 2-year old child must have received 24+ doses within the time frames established in the immunization schedule published by the U.S. Centers for Disease Control and Prevention. Not even one dose of one vaccine can be missed or administered late. This strict definition is why the rates for the 10-vaccine bundle are so much lower than the rates for any individual immunization.
The percentage of 2-year-olds served by MaineHealth practices that are up-to-date on all 10 vaccines has risen from 54% in 2015 to 59% in 2018.
Across MaineHealth member-owned practices, up-to-date rates for five of the 10 individual vaccines increased from 2014 to 2017. Furthermore, the 2017 rates for eight of the 10 vaccines exceeded the Healthy People 2020 targets.
The U.S. Centers for Disease Control and Prevention (CDC) currently recommends 10 immunizations be fully administered to all children by age 2. At this time, the National Immunization Survey (NIS) does not calculate up-to-date rates for the 10-vaccine bundle but rather the seven-vaccine bundle rates (19+ doses on time). The fluctuations in Maine’s NIS estimated rates are due to the statistical limitations of surveying small samples of 200 to 250 parents per year. Because of the small samples in the NIS, the Maine Center for Disease Control and Prevention estimates more reliable up-to-date rates for the seven-vaccine bundle using data submitted by providers to ImmPact, Maine’s Immunization Information System. As of January 1, 2018, 73.5% of 2-year olds were up-to-date for the seven-vaccine bundle.
Both the Maine and U.S. estimates were below the Healthy People 2020 target of 80% and the MaineHealth goal rate of 85%.
