Accuracy of influenza vaccination status in a computer-based immunization tracking system of a managed care organization.
Summary of "Accuracy of influenza vaccination status in a computer-based immunization tracking system of a managed care organization."
Influenza vaccine safety and effectiveness studies conducted using electronic medical records rely on accurate assessment of influenza vaccination status. However, influenza immunization in non-traditional settings (e.g., the workplace) may not be captured in patient immunization tracking systems. We compared influenza vaccination status from electronic records with self-reported vaccination status for five hundred and two 50-79 years olds enrolled in a large managed care organization. Influenza vaccination status in the medical record had a high positive predictive value and specificity (both >99%). The negative predictive value was 80% and sensitivity was 78%. These data suggest that an electronic record of influenza vaccination reliably indicates immunization, while the absence of such a record is only moderately accurate, partly due to vaccines received in non-traditional settings.

Medical and Biotech [MESH] Definitions
Computer-based representation of physical systems and phenomena such as chemical processes.
Any immunization following a primary immunization and involving exposure to the same or a closely related antigen.
Influenza B Virus
Species of the genus INFLUENZAVIRUS B that cause HUMAN INFLUENZA and other diseases primarily in humans. Antigenic variation is less extensive than in type A viruses (INFLUENZA A VIRUS) and consequently there is no basis for distinct subtypes or variants. Epidemics are less likely than with INFLUENZA A VIRUS and there have been no pandemics. Previously only found in humans, Influenza B virus has been isolated from seals which may constitute the animal reservoir from which humans are exposed.
Protection from an infectious disease agent that is mediated by B- and T- LYMPHOCYTES following exposure to specific antigen, and characterized by IMMUNOLOGIC MEMORY. It can result from either previous infection with that agent or vaccination (IMMUNITY, ACTIVE), or transfer of antibody or lymphocytes from an immune donor (IMMUNIZATION, PASSIVE).
Hemagglutinin Glycoproteins, Influenza Virus
Membrane glycoproteins from influenza viruses which are involved in hemagglutination, virus attachment, and envelope fusion. Fourteen distinct subtypes of HA glycoproteins and nine of NA glycoproteins have been identified from INFLUENZA A VIRUS; no subtypes have been identified for Influenza B or Influenza C viruses.
