Poor quality of primary care providers' vaccine recommendations lead to low adolescent human papillomavirus vaccination rates and hundreds of thousands of adolescents unnecessarily at risk for HPV-associated cancers and diseases. Though a previous provider communication intervention, called PCOM, was found to be effective for increasing adolescent HPV vaccination in primary care, its dissemination is limited by the need for significant research team involvement to teach providers how to use the intervention's components. To address this, investigators propose to develop and test a virtual version of PCOM, use mixed methods to assess contextual factors affecting its use compared to the original PCOM intervention, and develop an optimized version of PCOM for broad dissemination to increase adolescent HPV vaccination nationally.
