Patterns of healthcare visits and vaccination among adolescents and young adults 16–23-years-old: a retrospective US claims database analysis

Approximately one-third of commercially insured 16-23-year-olds did not have an annual HCP visit, and among commercially insured and Medicaid-insured individuals who did have visits, a substantial proportion did not have preventative visits; this proportion was higher with increasing age. The proportions of visits with vaccination were particularly low for 19-23-year-olds. Targeted interventions to promote routine visits, including framing these as opportunities for immunization, may help to increase vaccination uptake; based on the findings of this analysis, these efforts should consider age-specific shifts in health-seeking behaviors.
