9. Flu vaccination rates amongst high risk pediatric populations



Click image to enlarge



In the 2017-2018 influenza season, influenza accounted for more than 48,000 hospitalizations in pediatric patients. At the Children's Hospital of Wisconsin-Fox Valley subspecialty clinics, influenza vaccines are available in the Asthma/Allergy program while Cardiology patients may receive the influenza vaccine at an alternate location. The purpose of the study was to determine the influenza vaccination rates of high-risk pediatric patients seen in these clinics and to determine if there is a significant difference in vaccination rates based on differing clinical operations. A retrospective chart review was completed to assess the influenza vaccination rates among patients with reactive airway disease or structural heart defects seen in both clinics during the 2017-2018 influenza season. The vaccination rate in the Asthma/Allergy clinic was 63.5%, while the vaccination rate in the Cardiology clinic was 52.3%. This difference in vaccination rates was determined to be statistically significant (p=0.0285, p<0.05). Among asthmatics, patients with persistent disease had the highest vaccination rates. Furthermore, vaccination rates increased with increasing cardiac complexity. This data suggests that offering the influenza vaccine in subspecialty clinics improves overall vaccination rates, but further prospective studies are needed to confirm these findings.
