研究概览
简要总结
The University of North Carolina will test the effectiveness of the Centers for Disease Control and Prevention's AFIX model for increasing HPV vaccination coverage among adolescents. AFIX (Assessment, Feedback, Incentives and eXchange) consists of brief quality improvement consultations that immunization specialists from state health departments deliver to vaccine providers in primary care settings. Using immunization registry data, the specialist evaluates the clinic's vaccination coverage and delivers education on best practices to improve coverage. We will compare changes in HPV vaccination coverage before and after consultations for high-volume pediatric and family medicine clinics across three study conditions: traditional consultations (in-person group), virtual consultations (webinar group), or no consultations (control group). In each participating state, 30 clinics will be randomly assigned to each study arm, for a total of 90 clinics per state, or 270 clinics overall. The primary objective of this study is to compare the change in coverage for HPV vaccine initiation among 11-12 year old patients, from baseline to 6-month follow-up. Secondarily, we will compare the change in coverage for other vaccines and age groups.

研究组 & 干预措施
control
This arm includes 30 high-volume primary care clinics in each of three states (Washington, Illinois, Michigan) for a total of 90 clinics. Clinics randomly assigned to this arm will receive no AFIX consultation.
AFIX in-person consultation
This arm includes 30 high-volume primary care clinics in each of three states (Washington, Illinois, Michigan) for a total of 90 clinics. Clinics randomly assigned to this arm will receive an in-person AFIX consultation. Consultations will be delivered by state health department staff.
干预措施: AFIX in-person consultation (Other)
AFIX webinar consultation
This arm includes 30 high-volume primary care clinics in each of three states (Washington, Illinois, Michigan) for a total of 90. Clinics randomly assigned to this arm will receive an AFIX consultation via interactive webinar. Consultations will be delivered by state health department staff.
干预措施: AFIX webinar consultation (Other)

Coverage change from baseline to six months in HPV vaccine initiation (≥1 dose), among 11- to 12-year old patients in the control arm versus the combined in-person and webinar intervention arms, as measured by electronic immunization information system (IIS) records, controlling for child's sex
