IMPORTANCE The incidence of human papillomavirus (HPV)-related cancers is more than 35 000 cases in the United States each year. Effective HPV vaccines have been available in the United States for several years but are underused among adolescents, the target population for vaccination. Interventions to increase uptake are needed. OBJECTIVE To evaluate the effect of a 5-component health care professional HPV vaccine communication intervention on adolescent HPV vaccination. DESIGN, SETTING, AND PARTICIPANTS A cluster randomized clinical trial using covariate-constrained randomization to assign study arms and an intent-to-treat protocol was conducted in 16 primary care practices in the Denver, Colorado, metropolitan area. Participants included 188 medical professionals and 43 132 adolescents. INTERVENTIONS The 5 components of the intervention were an HPV fact sheet library to create customized information sheets relevant to each practice's patient population, a tailored parent education website, a set of HPV-related disease images, an HPV vaccine decision aid, and 2½ hours of communication training on using a presumptive vaccine recommendation, followed by motivational interviewing if parents were resistant to vaccination. Each practice participated in a series of 2 intervention development meetings over a 6-month period (August 1, 2014, to January 31, 2015) before the intervention. MAIN OUTCOMES AND MEASURES Differences between control and intervention changes over time (ie, difference in differences between the baseline and intervention period cohorts of patients) in HPV vaccine series initiation (Ն1 dose) and completion (Ն3 doses) among patients aged 11 to 17 years seen at the practices between February 1, 2015, and January 31, 2016. Vaccination data were obtained from the practices' records and augmented with state immunization information system data. RESULTS Sixteen practices and 43 132 patients (50.3% female; median age, 12.6 years [interquartile range, 10.8-14.7 years] at the beginning of the study period) participated in this trial. Adolescents in the intervention practices had significantly higher odds of HPV vaccine series initiation (adjusted odds ratio [aOR], 1.46; 95% CI, 1.31-1.62) and completion (aOR, 1.56; 95% CI, 1.27-1.92) than those in the control practices (a 9.5-absolute percentage point increase in HPV vaccine series initiation and a 4.4-absolute percentage point increase in HPV vaccine series completion in intervention practices). The intervention had a greater effect in pediatric practices compared with family medicine practices and in private practices compared with public ones. Health care professionals reported that communication training and the fact sheets were the most used and useful intervention components. CONCLUSIONS AND RELEVANCE A health care professional communication intervention significantly improved HPV vaccine series initiation and completion among adolescent patients. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT02456077

Human papillomavirus (HPV) vaccine uptake is below that of other routine adolescent vaccines. This is due in part to the fact that the HPV vaccine is often not routinely recommended by providers to all eligible adolescents. While providers' recommendations are crucial, even a strongly stated recommendation can be insufficient among HPV vaccine-hesitant parents. Providers must be prepared to respond to parental concerns following giving the recommendation for the HPV vaccine. This paper presents the analysis of implementation of an intervention aimed at improving provider communication with HPV vaccine-hesitant parents. Healthcare providers and staff at eight pediatric and family medicine clinics received communication training that included motivational interviewing (MI) techniques. Process evaluation in the form of serial surveys, as well as program evaluation in the form of focus groups with participating providers and staff, assessed the perceived efficacy of the intervention. Outcomes included time spent discussing the HPV vaccine during clinical visits, providers' self-efficacy for addressing parental HPV vaccine hesitancy, and their general perceptions of the effectiveness of MI techniques. Overall, findings indicate the intervention improved providers' communication with HPV vaccine-hesitant parents and providers reported the use of MI played a central role in improved HPV vaccine acceptance. Lessons learned and recommendations for future interventions are also discussed.

OBJECTIVE: School-based health centers (SBHCs) have been suggested as possible patient-centered medical homes. Our objectives were to determine, in a low-income, urban population, adolescents’ reasons for visiting SBHCs and the value parents place on SBHC services, and adolescents’ and parents’ assessment of how well SBHCs fulfill criteria for a medical home as defined by the American Academy of Pediatrics. METHODS: A cross-sectional, mailed survey of a random sample of 495 adolescent SBHC users and 497 parents of SBHC users from 10 SBHCs in Denver, CO from May to October 2012. Eligible adolescents were registered in an SBHC with ≥1 visit during the 2011 to 2012 school year. RESULTS: Response rates were 40% (198/495) among adolescents and 36% (181/497) among parents. The top 3 reasons for visits were for illness (78%), vaccines (69%), and sexual health education (63%). Factors reported as very important by >75% of parents in the decision to enroll their adolescent in an SBHC included clinic offering sick or injury visits, sports physicals, and vaccinations. More than 70% of adolescents gave favorable responses (always or usually, excellent or good) to questions about American Academy of Pediatrics medical home criteria (accessibility, continuity, comprehensiveness, family-centeredness, coordination, and compassion). Most parents (83%) reported that they could always or usually trust the SBHC provider to take good care of their child; 82% were satisfied with provider-to-provider communication. CONCLUSIONS: In a low-income urban population, SBHCs met criteria of a medical home from adolescents’ and parents’ perspectives. Policymakers and communities should recognize that SBHCs play an important role in the medical community, especially for underserved adolescents.
