Vaccination Programs: Immunization Information Systems

CDC

An Evidence-Based Practice

Description

Immunization information systems (IIS) are confidential, population-based, computerized databases that record all immunization doses given by participating providers to people who live within a certain geopolitical area.
Immunization information systems are set up to do the following:

-Create or support effective interventions, such as client reminder and recall systems, provider assessment and feedback, and provider reminders
-Determine client vaccination status to aid decisions made by clinicians, health departments, and schools
-Guide public health responses to outbreaks of vaccine-preventable disease
-Inform assessments of vaccination coverage, missed vaccination opportunities, invalid dose administration, and disparities in vaccination coverage
-Facilitate vaccine management and accountability

Results / Accomplishments

The Community Preventive Services Task Force (CPSTF) recommends immunization information systems (IIS) to increase vaccination rates. The CPSTF finding is based on evidence from a systematic review of 240 studies (108 published studies and 132 conference abstracts; search period January 1994 – April 2011). Included studies represented IIS-supported interventions (e.g., client reminder and recall systems) and described IIS program activities and experiences. The review was conducted on behalf of the CPSTF by a team of specialists in systematic review methods, and in research, practice, and policy related to increasing appropriate vaccination.

An Evidence-Based Practice meets the following HCI criteria:

  1. The program description includes at a minimum: the sponsoring organization, program goals, program implementation steps, and outcomes that have demonstrated program success in achieving the program goal in one or more localities.
  2. The results from an evaluation of the program include quantitative measures showing improvement in the outcome(s) of interest after the implementation of the program (i.e. increase in smoking cessation, not just the delivery of a smoking cessation program). The outcome measure(s) is/are compared at relevant time periods before and after the intervention or program implementation. Alternatively, the evaluation study compares the outcome(s) between an intervention group and an appropriate control group.
  3. The study is of peer-review quality and presents numbers in a scientific manner; measurements of precision and reliability are included (e.g. confidence intervals, standard errors), results from statistical tests show a significant difference or change in the outcome measure(s), and relevant point estimates and p-values are presented. Note: if the results from an evaluation of a program are presented in a scientific manner and the outcome measure is improved compared to the baseline measurement or the control group but the difference is not statistically significant, the practice is classified as effective and not evidence-based.
