Public Health and Immunization Registries

Public health information systems like immunization registries can meet public health demands for assurance and assessment, support clinical decision-making and offer cost effective quality healthcare.

Public Health System

The areas of concern in healthcare emphasized are methods of prevention, access to quality and affordable healthcare which is dependent on the availability and support of information collected, analyzed, recorded and disseminated through developed health information systems. Electronic health records in medical arena help control costs, allow quality healthcare coordination, reduce errors and unnecessary testing. Electronic health records are a tool used to improve health information exchange and deliver health services to healthcare providers by facilitating the transfer of medical information.

Easy transfer of electronic medical records and health related information of patients across institutions or organizations according to nationally recognized standards is possible through public health information systems. Public health information systems provide important information on under served geographic areas, environmental influences on health or disease trends, concentrations of unfavorable health indicators and outbreaks. They allow assessment of health status disparities in population based on race or ethnicity, age, gender and other factors.
Merely summing data from electronic health records together will not provide a comprehensive picture of the population, which is essential for tracking disease trends and treatment outcomes. Comparative effectiveness researchof a national distributed health data networks or electronic practice-based networkscan support quality improvement or translational research activities.
Public healthcare system of electronic health information and records such as immunization registries are necessary components of the information infrastructure that assesses impact of healthcare changes on the population. Immunization information systems form a link between health care delivery and population based data. They are more mature, developed and standardized than other population based or public health information systems. Attributes of clinical information system of individually focused records of healthcare care delivered to adults and children is present in immunization registries. They are the public health database best suited for collecting comprehensive health information and providing clinical decision-making support.


Immunization registry is a valuable public health tool for improving delivery of immunization and delineating patterns of care by consolidating immunization records from multiple sources that have direct implications for health care planning and policy. Development of immunization registries is a means of helping public health officials and clinicians to increase updated rates of immunization, better patient tracking, improved recall and reminder efforts and preventing over-immunization. These registries are computerized confidential information systems of immunizations records. Immunization registries contain immunizations information received from the population of a particular geographic area.
Immunization registry is a healthcare tool to overcome barriers in effective immunization delivery. The potential benefit of consolidating records in immunization registries to individual or private practice sectors or public health clinics is that it reduces the frequency of missed opportunities, eliminates record scatter and facilitates immunization reminder or recall notices. A registry provides immunization delivery for preventive care and is a valuable public health tool that offers insight into documentation at population level. It helps persuade health care providers on the importance of policy implications and face deficiencies in the delivery and record patterns of immunization.
An immunization registry also contains database of children in a defined geographic location or population collected from private and public providers, schools, parents, and other agencies. The computerized information in the registry is used to track and record immunizations delivered to each child. The goal of improving immunization delivery in children requires cooperation among healthcare delivery system of different sectors within a community. Lack of accurate and timely immunization information in children among parents and healthcare providers can fail to delivery immunization to under served and poor population. These registries help healthcare providers to track and improve range of child health services. The challenge of monitoring and assessing healthcare problems in a population is sorted by innovative technologic solutions of immunization registries.
