The purpose and functions of immunization information systems within health care organizations

Abroad coalition of public and private health care organizations advocate the development of computerized immunization information systems as a key national strategy for achieving and sustaining high immunization coverage levels. However- widespread adoption requires greater awareness of the purpose- functions- and value of an immunization information system within health care organizations. We propose that the purpose of an immunization information system is to increase the efficiency and effectiveness of immunization-related practices and identify 9 potential functions that accomplish this purpose through improving patient care and practice management. When implementing an immunization information system within a practice setting- health care providers must consider technological and organizational issues. Health care providers should also look beyond their particular practice setting and establish public-private partnerships to create a system that links immunization data from all health care providers.
