Human Papillomavirus Vaccination of Adolescents with Chronic Medical Conditions: A National Survey of Pediatric Subspecialists.

STUDY
OBJECTIVE: Many adolescents with chronic medical conditions (CMCs) are at risk of human papillomavirus (HPV) infection, associated complications, and underimmunization and often identify a pediatric subspecialist as their main provider. This study aimed to assess the HPV-related understanding, beliefs, and practices of pediatric subspecialists, which are largely unknown. DESIGN AND
SETTING: National cross-sectional study. PARTICIPANTS: Pediatric endocrinologists, hematologist/oncologists, pulmonologists, and rheumatologists identified using the American Medical Association Physician Masterfile (n = 418).
INTERVENTIONS: Subspecialists who care for adolescents with CMCs in the outpatient setting were recruited to complete a Web-based survey on their HPV-related knowledge, attitudes, comfort, and practices. MAIN OUTCOME MEASURES: HPV vaccination recommendation.
RESULTS: Over half of respondents (50.4%; n = 196/389) reported sometimes or always recommending HPV vaccination to adolescent patients with CMCs. Factors positively associated with recommendation included hematology/oncology (adjusted odds ratio [AOR], 4.69; 95% confidence interval [CI], 1.86-11.81) or rheumatology (AOR, 6.55; 95% CI, 1.67-25.74) specialization, seeing more adolescent patients with CMCs (AOR, 1.01; 95% CI, 1.00-1.02), and sometimes or always discussing sexual health (AOR, 2.53; 95% CI, 1.05-6.08) or checking vaccine status (AOR, 3.83; 95% CI, 1.59-9.20) with these patients. Those who thought it was important, but were uncomfortable discussing sexual health when recommending HPV vaccination (AOR, 0.28; 95% CI, 0.12-0.70) or who reported insufficient HPV vaccine information (AOR, 0.45; 95% CI, 0.23-0.88) or lack of primary-subspecialty care provider communication (AOR, 0.38; 95% CI, 0.16-0.93) as barriers to HPV vaccination were less likely to recommend HPV vaccination.
CONCLUSION: This study revealed that many subspecialists fail to recommend HPV vaccination to adolescents with CMCs and highlights potential targets for future interventions.
