Strengthening Physician Communication About HPV Vaccines

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine if a multimodal Human Papillomavirus (HPV) immunization program carried out in pediatric and family medicine practices would be more effective in improving adolescent patients' HPV immunization rates than the usual care provided to adolescents in pediatric and family medicine practices.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Intervention Practices<br>Intervention offices will adopt a multi-modal vaccine program to increase their patients' vaccine rates. | Behavioral: Multimodal Vaccine Program<br>* Efforts will be made to collaborate with pediatric and family medicine offices to utilize a multimodal intervention to improve adolescents' HPV immunization rates. As part of the overall intervention, four intervention strategies will be used: 1) a tailored website, iVac -HPV , 2) Motivational Interview Training for providers, 3) HPV Fact Sheets and 4) The Decision Aid for HPV Vaccines<br>|
| No Intervention: Control Practices<br>Control offices will offer usual health care related to immunizations throughout the duration of the study. | |

What is the study measuring?

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The percentage of adolescents who initiate the HPV vaccine series | The percent of eligible patients presenting for care at intervention offices who receive one or more HPV vaccines (using administrative, Electronic Medical Records (EMR), and Colorado Immunization Information System (CIIS) immunization data), during the intervention year, compared to the percent in control offices. | 1 year | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The percentage of adolescents who receive MCV4 vaccine | The percent of eligible patients presenting for care at intervention offices who receive MCV4 vaccine (using administrative, EMR and CIIS immunization data) compared to the percent in control offices. | 1 year | 
| The percentage of adolescents who receive Tdap vaccine | The percentage of eligible patients presenting for care at intervention offices who receive Tetanus, Diphtheria, Pertussis (Tdap) vaccine (using administrative, EMR and CIIS immunization data) during the intervention year compared to the percent in control offices. | 1 year | 
| Provider HPV vaccine recommendations | The change in intervention providers' HPV vaccine communication practices compared to control providers' as measured by self-report prior to the intervention and after the intervention. | 1 year | 
| Parents' experiences and preferences regarding provider communication about HPV vaccines | The change in intervention parents' experiences and preferences regarding provider HPV vaccine communication compared to parents of adolescents attending control practices as measured by self report prior to the intervention and after the intervention. | 1 year |
