Abstract

Background and objective: The risk of bacterial meningitis increases in cochlear implant patients. Therefore, pneumococcal, influenza and Haemophilus influenzae type b vaccination is indicated in this group. The aim of this study was to determine compliance with the vaccination calendar in patients implanted in a referral hospital.

Materials and methods: Patients with cochlear implant operated between 2005 and 2015 were included. Vaccine coverage for seasonal influenza, Haemophilus influenzae type b and pneumococcal conjugate 13-serotypes and pneumococcal polysaccharide 23-serotypes was evaluated. The sample was divided into 2 age groups (<14 years and≥14 years). A univariate and bivariate analysis was performed.

Results: Of the 153 patients studied (28.01% 0-13 years old and 71.9%≥14), only 2 (5.71%) had 100% adherence to the vaccination schedule, while 65.71% had compliance of 50% or less. Overall, vaccination coverage against the sequential pneumococcal pattern was 48.57%. The paediatric population exceeded 90% coverage for the vaccine against Haemophilus influenzae type b and pneumococcal conjugate 13-serotypes while in those over 14 years of age it barely exceeded 50%. Influenza coverage was less than 40%. An inverse correlation was obtained between age and compliance, although not statistically significant.

Conclusions: Vaccination coverage in patients with cochlear implant is lower than expected. Close collaboration between Otolaryngology departments and the Vaccination Units is proposed as the main strategy for improvement.
