LAKE BUENA VISTA, FLA. – Nearly 44% of incompletely vaccinated inpatients with influenza had a missed opportunity for vaccination, according to retrospective chart review at Children’s Hospital Colorado.
Among 197 such children admitted with confirmed influenza in 2010-2014, 86 (44%) had a total of 507 medical visits during which influenza vaccine was available, Dr. Suchitra Rao of the University of Colorado, Denver, reported in a poster at the Pediatric Hospital Medicine 2014 meeting.
The majority of patients with missed opportunity visits were considered high risk for severe complications from influenza from factors such as age younger than 2 years, immunosuppression, pregnancy, or an underlying chronic pulmonary, cardiovascular, renal, hepatic, neurological, hematologic, or metabolic disorder, although this finding was not statistically significant, Dr. Rao reported.
The bulk of missed opportunity visits occurred during September, October, and November (20%-23% each month) prior to onset of the influenza season, with declining percentages taking place between December and April. Most of the visits (45%) occurred at specialty clinics, followed by the emergency department or urgent care setting (22%).
"Subspecialty outpatient visits provide an excellent opportunity for influenza vaccination because they target high-risk patients and they represent the highest proportion of missed opportunities for vaccination," Dr. Rao and her colleagues wrote.
Future analyses will explore independent risk factors for missed opportunities, and identify differences in visit characteristic for high vs. low risk groups, they noted.
The Pediatric Hospital Medicine 2014 meeting was sponsored by the Society of Hospital Medicine, the American Academy of Pediatrics, the AAP Section on Hospital Medicine, and the Academic Pediatric Association.
