DOSE HPV: Development of Systems and Education to Improve HPV Vaccination Rates

BACKGROUND

Human Papillomavirus (HPV) causes cervical, vaginal, vulvar, anal, and oral cancers, which disproportionately affect low-income and minority populations. Universal HPV vaccination has the potential to decrease burdens and to reduce disparities in these diseases. However, HPV vaccination rates for U.S. adolescents remain low. Clinician recommendation is the most important factor influencing HPV vaccine uptake; thus enhancing clinician communication about HPV vaccines is a critically important target for interventions to prevent cancer.

OBJECTIVE

In the past six years, the investigators' research has identified factors affecting HPV vaccine communication and utilization. the investigators recently piloted a communication intervention with clinicians, and at the two pilot intervention sites, girls were 60% and boys were 15 times more likely to receive HPV vaccination than at control sites both during and after the intervention period. The investigators aim to demonstrate the effectiveness of this intervention in a randomized trial, and to directly examine its effects on communication.

SPECIFIC AIMS

Aim 1. To evaluate intervention effectiveness on raising HPV vaccination rates using a stepped wedge randomized trial in federally qualified health centers.

Aim 2: To conduct a process evaluation that examines barriers and facilitators to intervention implementation and intervention sustainability, and to assess intervention fidelity.

Aim 3. To describe specific effects of the intervention on clinician-parent communication about HPV vaccination.

STUDY DESIGN

To address Aim 1, the investigators will perform a stepped wedge randomized trial in five community health centers to determine the effectiveness of the intervention. The intervention consists of a seven session Performance Improvement Continuing Medical Education (PI CME) program that employs HPV education and training in motivational interviewing to improve clinicians' HPV vaccine communication, and allows clinicians to improve the quality of vaccine care while fulfilling board certification requirements. To address Aim 2, the investigators will individually interview a selected group of providers and clinical leaders using the Promoting Action on Research Implementation in Health Services (PARiHS) model of process evaluation, and will analyze audio recordings of clinical interactions to measure intervention fidelity. Aim 3, an exploration of the intervention's effects on parent-clinician communication, will be conducted by surveying parents and clinicians and observing clinical encounters.

CANCER RELEVANCE

Rates of HPV related cancers have been increasing, but vaccination rates have remained stagnant since 2011. Recognizing the potential impact of HPV vaccination, the President's Cancer Panel stated in 2014 that raising HPV vaccination rates was a national priority. The proposed intervention represents an innovative and scalable model for promoting cancer prevention and screening activities by clinicians.
