Sponsor's own description
Most adolescents who receive human papillomavirus (HPV) vaccine are vaccinated in pediatric practices, yet missed opportunities (MOs) for HPV vaccination occur often and lead to low HPV vaccination rates. This single-arm study (embedded within arm 2 of a 2-arm cluster randomized clinical trial (RCT)) will test the effectiveness (and cost-effectiveness) of a bundled intervention (HPV vaccine communication, performance feedback reports and provider prompts), in practices that previously received standard of care, to reduce MOs and increase HPV vaccination rates.
