Objective:
To demonstrate the use of a state-maintained database (CHILD Profile) to monitor immunization status of pediatric cochlear implant recipients, and to assess compliance with current vaccination recommendations for cochlear implant users managed at Seattle Children's Hospital.
Study Design:
Cross-sectional study.
Setting:
Tertiary academic pediatric hospital.
Subjects And Methods:
Subjects were 260 patients with cochlear implants managed at Seattle Children's Hospital between July 1, 1995, and May 1, 2008. Patients were stratified by age groups (0-2 years, 2-5 years, 5-10 years, > 10 years). Using a statewide children's immunization registry (CHILD Profile), subjects were assessed with regard to their immunization status for Haemophilus influenzae type B vaccination (HiB), 7-valent pneumococcal conjugate vaccination (PCV-7), and 23-valent pneumococcal polysaccharide vaccine (PPV-23).
Results:
Two hundred twenty-five of 260 subjects (87%) were registered in CHILD Profile; 126 of 225 (56%) were up to date with CDC recommendations for patients with cochlear implants. PPV-23 was the vaccination most likely to be incomplete. Age was predictive of immunization status only with HiB vaccination.
Conclusion:
A statewide immunization registry can be used to monitor the immunization status of cochlear implant recipients. Subjects were significantly more likely to be incomplete for PPV-23 than for either PCV-7 or HiB vaccinations.
