Partnership between Boise State University & Central District Health Department
Enhance safe immunization practices Healthy People 2010 - 90% immunization coverage
rates in the State of Idaho Increase accountability and safe immunization
delivery: Promoting legislative changes to follow the ACIP’s
immunization recommendations Educating physicians, nurses, medical assistants,
school nurses, and child care providers, many of whom are responsible for the administration and delivery of immunizations
![Page 5: IMMUNIZATION EDUCATION Are Vaccines Safe and Effective?](https://reader030.fdocuments.in/reader030/viewer/2022012906/56649e245503460f94b12cb6/html5/thumbnails/5.jpg)
Problem Identification
Idaho is 49th in the US for immunization coverage!
![Page 6: IMMUNIZATION EDUCATION Are Vaccines Safe and Effective?](https://reader030.fdocuments.in/reader030/viewer/2022012906/56649e245503460f94b12cb6/html5/thumbnails/6.jpg)
Why is Idaho so low?
![Page 7: IMMUNIZATION EDUCATION Are Vaccines Safe and Effective?](https://reader030.fdocuments.in/reader030/viewer/2022012906/56649e245503460f94b12cb6/html5/thumbnails/7.jpg)
What if the vaccines we give are ineffective?
Increase the risk of disease Decrease immunization coverage Inappropriately stored vaccine results in
less vaccine availability Cost for vaccine to re-immunize 1 million
children = $20 million to $36 million
![Page 8: IMMUNIZATION EDUCATION Are Vaccines Safe and Effective?](https://reader030.fdocuments.in/reader030/viewer/2022012906/56649e245503460f94b12cb6/html5/thumbnails/8.jpg)
Invalid Immunizations:Literature Review
Common immunization errors: Injection of the wrong vaccine, improper time interval
between doses, and route of administration, and missed opportunities resulting in a late or missing immunization (Mell, et al., 2005; Stokely, Maurice, Smith, & Klevens, 2004)
Medical office personnel each give 6-20 vaccines per day
Vaccines to triple by the year 2020
10.5% of all children nationally receive at least one invalid dose
12% or more of Idaho children receive at least one invalid dose
![Page 9: IMMUNIZATION EDUCATION Are Vaccines Safe and Effective?](https://reader030.fdocuments.in/reader030/viewer/2022012906/56649e245503460f94b12cb6/html5/thumbnails/9.jpg)
Invalid Immunizations - Midwest USA
In Iowa, 224 children received Varivax inappropriately stored.
Titers & reimmunized 42% of the children 6% had evidence of chicken pox like rash on
their medical records but not diagnosed as such
32 occasions of incorrect storage Cost = $750,000 (Welte, 2007)
![Page 10: IMMUNIZATION EDUCATION Are Vaccines Safe and Effective?](https://reader030.fdocuments.in/reader030/viewer/2022012906/56649e245503460f94b12cb6/html5/thumbnails/10.jpg)
Invalid Immunizations cont…..
30% of vaccine errors resulted from inappropriate scheduling (CDC, 2007)
Out of 16,211 children only 9% received immunizations at recommended ages
(Lumin, McCauley, Stokely, Chu, and Pickering. 2002)
53-82% of all vaccine shipments in the world are compromised in some way (Techathawat, Varinsathien, Rasdjarmrearnsook, & Tharmaphornpilas, 2007)
Forty five percent of all immunizations expire before they are used (JAMC, 2004)
![Page 11: IMMUNIZATION EDUCATION Are Vaccines Safe and Effective?](https://reader030.fdocuments.in/reader030/viewer/2022012906/56649e245503460f94b12cb6/html5/thumbnails/11.jpg)
Invalid Immunizations cont…..
Storage and handling issues are directly related to the personnel managing vaccines in the medical offices
(Bell, Hogue, Manning, & Kendal, 2001; Welte, 2007)
Failure to adhere to recommended specifications for storage and handling can reduce vaccine potency, resulting in inadequate immune response in the recipient
(Kroger, Atkinson, Marcues, & Pickering, 2006)
Craig (2008) reports diminished potency of the vaccine affects natural immune response, inadequately protects against diseases, and increases risk of adverse reactions

Research Questions
Research question(s):
1. What proportion of health care providers in Idaho have adequate knowledge regarding administration and storage of the MMR (measles, mumps, rubella) vaccines?
2. Are there significant differences among health care provider types in the proportion with adequate knowledge regarding administration and storage of the MMR (measles, mumps, rubella) vaccine?

Results of Immunization Survey
Educational opportunities: Route Storage
Physicians, Nurse Practitioners and “other” category, i.e., pharmacists, require the most information and education
Immediate access to timely information is essential
Increased understanding increases compliance and greater immunization coverage
![Page 33: IMMUNIZATION EDUCATION Are Vaccines Safe and Effective?](https://reader030.fdocuments.in/reader030/viewer/2022012906/56649e245503460f94b12cb6/html5/thumbnails/33.jpg)
Recommendations for Further Study…
Research disease outbreaks & causes Connect to storage and administration
Standardize immunization education & training Change Idaho legislation to follow ACIP
recommendations Nationwide study on health care personnel
administering immunizations Peer education interventions to significantly
improve provider immunization knowledge and behaviors (Boom, et. al, 2007)
![Page 34: IMMUNIZATION EDUCATION Are Vaccines Safe and Effective?](https://reader030.fdocuments.in/reader030/viewer/2022012906/56649e245503460f94b12cb6/html5/thumbnails/34.jpg)
Immunization Education Program through Central District Health Department
Identify individual personnel educational needs, urban vs. rural educational needs, district educational needs
Education and training will be provided to 30 medical offices compared to 30 offices without training over the next 2 years
Grants received Jekker Trust Fund - $20,000 Regence Foundation – $49,000 Central District Health Department - $20,000
