Prevention of Perinatal Transmission of Hepatitis B Virus: Assessment Among Wisconsin Maternity Hospitals.

Purpose: To evaluate the completeness of identification of pregnant women testing positive for hepatitis B surface antigen (HBsAg) and birth dose hepatitis B vaccine administration, and the extent of appropriate prophylaxis of infants born to women with and without maternal HBsAg status documented in the infant medical record.

Methods: We conducted medical record reviews of 3058 maternal and infant pairs at 58 Wisconsin maternity hospitals that cumulatively delivered 90% of Wisconsin's 2010 birth cohort.

Results: A documented HBsAg test result for the current pregnancy was included in 2928 (95.

Pertussis and Influenza Vaccination Among Insured Pregnant Women — Wisconsin, 2013-2014.

On February 22, 2013, the Advisory Committee on Immunization Practices (ACIP) revised recommendations for vaccination of pregnant women to recommend tetanus-diphtheria-acellular pertussis vaccine (Tdap) during every pregnancy, optimally at 27-36 weeks of gestation, to prevent pertussis among their newborns. Since 2004, influenza vaccination has been recommended for pregnant women in any trimester to prevent influenza and associated complications for mother and newborn. To evaluate vaccination of pregnant women in Wisconsin after the 2013 Tdap recommendation, health insurance claims data for approximately 49% of Wisconsin births were analyzed.

Completeness and accuracy of the wisconsin immunization registry: an evaluation coinciding with the beginning of meaningful use.

Context: Vaccination coverage rates can be improved through the application of complete and accurate immunization information systems (IISs).

Objective: Evaluate the completeness and accuracy of Wisconsin's IIS, the Wisconsin Immunization Registry (WIR).

Design: Cross-sectional evaluation, comparing vaccination medical records (MRs) from provider clinics with WIR records.

The Wisconsin immunization registry experience: comparing real-time and batched file submissions from health care providers.

Context: The Wisconsin Immunization Registry is a confidential, web-based system used since 1999 as a centralized repository of immunization information for Wisconsin residents.

Objective: Provide evidence based on Registry experiences with electronic data exchange, comparing the benefits and drawbacks of using the Health Level 7 standard, including the option for real time data exchange vs the flat file method.

Design: For data regarding vaccinations received by children aged 4 months through 6 years with Wisconsin addresses that were submitted to the Registry during 2010 and 2011, data timeliness (days from vaccine administration to date information was received) and completeness (percentage of records received that include core data elements for electronic storage) were compared by file submission method.
