Improving Immunization Rates


Shot TimeThe practice participated in the PROTECT performance improvement modules (PIM) for both childhood and adolescent immunizations, and we are pleased to announce our results.


Our goal for the childhood immunizations was to improve the number of children receiving their second Hepatitis A vaccine before their second birthday. We were able to improve our rate from 80 to 95%.

 Hepatitis A is a type of food poisoning spread by contaminated food and water. We thank parents for working with us to protect children from this serious communicable illness that causes serious jaundice and dehydration.

Our goal for adolescent immunizations was to improve the rate of human papilloma virus (HPV) vaccination. When we first looked at our data for girls:

100% of 9-13 year olds had received one dose of 

40% of 9-13 year olds had received all three doses of HPV.

For boys:


80% of 9-13 year olds had received one dose of HPV


20% of 9-13 year olds  had received all three doses of HPV.


After performance improvements, our rates for girls were relatively unchanged:


100% had received one dose, 36% had received all three doses.


For boys, however, 100% had received one dose and 40% had received all three doses.


HPV causes cancers of the cervix in women as well as throat and anal cancers in women and men, and as we approach the first decade of offering this immunization, we look forward to lower rates of these cancers as our patients move into adulthood.
