The Minnesota Department of Health (MDH) examined hospital practices as recommended by the Advisory Committee on Immunization Practice in 2005 that hepatitis B vaccine should be administered universally to newborn infants prior to hospital discharge and within 12 hours of birth if their mothers test positive or are admitted with unknown status for hepatitis B surface antigen.
The MDH conducted a survey of perinatal hepatitis B birth dosing policies in Minnesota birthing hospitals, which prompted (1) and investigation of hospital birth dose rates from the Immunization Information System (IIS) and (2) a chart review of three selected hospitals with low rates.
The (IIS) records of children born in Minnesota during 2007 and the first 5 months of 2008 showed a hepatitis B birth dose rate that was lower than expected (2007: 37%; 2008: 48%). The chart review of three hospitals with low birth does rates showed rates for the first 6 months of 2008 of 94%, 89%, and 91% compared with IIS rates of 1.4%, 40%, and 39% respectively, during the same time period.
These results prompted MDH to increase efforts to provide education to birth registrars on the importance of hepatitis B vaccine data on the birth certificate and to promote regular transmission of hospital vaccination data to the IIS.
"The most common reason for excluding records after full text review was that the article did not identify any barriers to, or factors supporting, either any aspect of the IS or data quality. Our review process resulted in 23 total studies of which 11 reported on immunization information system (IIS),1,15–24 11 on vital record systems,25–35 and 1 described a public health information system that integrated vital records with other information systems.36 "
[Show abstract][Hide abstract] ABSTRACT: Public health professionals rely on quantitative data for the daily practice of public health as well as organizational decision making and planning. However, several factors work against effective data sharing among public health agencies in the US. This review characterizes the reported barriers and enablers of effective use of public health IS from an informatics perspective.
A systematic review of the English language literature for 2005 to 2011 followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) format. The review focused on immunization information systems (IIS) and vital records information systems (VRIS). Systems were described according to the structural aspects of IS integration and data quality.
Articles describing IIS documented issues pertaining to the distribution of the system, the autonomy of the data providers, the heterogeneous nature of information sharing as well as the quality of the data. Articles describing VRIS were focused much more heavily on data quality, particularly whether or not the data were free from errors.
For state and local practitioners to effectively utilize data, public health IS will have to overcome the challenges posed by a large number of autonomous data providers utilizing a variety of technologies.
[Show abstract][Hide abstract] ABSTRACT: Immunizations are an important component of the preventive services provided, managed and promoted by public health. The need to understand the information behaviors of public health practitioners related to immunizations has become more acute as health policy changes encourage the exchange of individual level immunization data between electronic health record (EHR) systems and Immunization Information Systems (IISs). We sought to further that understanding by conducting a series of interviews focused on information needs related to immunization administration and immunization data in Washington State. Interviews were conducted with public health practitioners who represented a variety of roles in local health jurisdictions. Following transcription, interviews were coded using qualitative data analysis software. Here, we will report on the thematic analysis of the interviews and preliminary interpretations and implications of our inquiry.

[Show abstract][Hide abstract] ABSTRACT: Health information systems receive data through various methods. These data exchange methods have the potential to influence data quality. We assessed a de-identified 2010 dataset including 757,476 demographic records and 2,634,101 vaccination records from Washington State's Immunization Information System (IIS) to describe timeliness and completeness of IIS data across several data exchange methods: manual entry, HL7, and flat file upload. Overall, manually-entered data and HL7 records were more timely than records imported as flat files. Completeness, though very high overall, was slightly higher for records arriving via flat file. Washington State IIS users, including clinicians and public health, rely on its data to inform patient care and determine population coverage of immunizations. Our results suggest that although data element completeness in systems like Washington's IIS will likely not be immediately or significantly impacted by provider's migration to HL7 connections with IISs, timeliness could be substantially improved when using HL7 connections.
