  • Contract with 35 Local Health Jurisdictions (LHJ’s) to provide services
  • Components:
    • State-supplied hepatitis B vaccine
    • Laboratory testing
    • Information, education, consultation and technical assistance
rational for selecting evaluation activity
Rational for Selecting Evaluation Activity

objectives
Objectives

1. By January 31, 2009, determine the number of providers identified by LHJ’s as caring for infants of HBsAg+ moms and number of providers with standing orders in place for post vaccination serology.

2. By March 31, 2009, survey providers identified as caring for infants of HBsAg+ moms to determine the percent of those providers who are:

a. aware of the value of early detection and the criticality of post serology testing for infants born to HBsAg positive moms

b. educated on the value of early detection and the criticality of post serology testing for infants born to HBsAg positive moms.

Objectives (Continued)

3. By December 31, 2009, increase the number of providers identified as caring for infants of HBsAg positive moms who are:

a. aware of the value of early detection and the criticality of post serology testing for infants born to HBsAg positive moms by 5%.

b. educated on the value of early detection and the criticality of post serology testing for infants born to HBsAg positive moms by 5%.

  • By December 31, 2009, the percent of providers who have written standing orders for post serology testing for infants born to HBSAg positive mothers will increase by 10%.
  • By December 31, 2010, the rate for a three-year period from December 31, 2006-December 31, 2009, for post serology testing for infants born to HBsAg positive mothers will increase from 58% to 70% (increase of 42 infants/yr).
evaluation activities
Evaluation Activities
  • Identify LHJ’s and geographical areas where post-vaccination serology is low.
  • Identify providers where post vaccination serology is low
evaluation activities11
Evaluation Activities
  • Plan outreach to providers to assess awareness of why infants born to HBsAg positive mom’s are not getting post-vaccination serology testing ( pre-test survey)
  • Use findings to develop strategies to increase the testing rates for these infants (post-test survey)
short term outcomes
Short-Term Outcomes
  • Providers are more aware of importance of post-vaccination serology testing
  • Providers are educated on the value of early detection
  • An increased number of providers who are conducting post-vaccination serology testing
  • An increase number of LHJ’s providing consultation with providers

Evaluation question #2:

Evaluation Question #4

  • To what degree did the rate for post-vaccination serology testing for infants born to HBsAg positive mothers increase from December 2006 (baseline collected in 2007) to December 2009 (collected in December 2010)
long term outcomes
Long term outcomes
  • An increase percentage of infants born to HBsAg positive moms who receive post-vaccination serology testing
  • An increase ability to track efficacy of Hepatitis B vaccination thru post-vaccination serology
  • A decrease in hepatitis B disease in infants born to HBsAg positive moms
