RESUMO
BACKGROUND: Human papillomavirus (HPV) vaccination uptake for adolescents and young adults in the United States remains far from national goals. Using a multi-component intervention aligned with community-wide efforts, we implemented a quality improvement project to increase HPV vaccinations among 9-26 year-old male and female patients in an urban, low income, minority population family medicine residency practice. METHODS: The pre-intervention year was November 2, 2014 to October 31, 2015 and the intervention year was November 1, 2015 to October 31, 2016. Based on community input and published literature, the interventions were creative, practice-specific provider-, patient-, and system-level strategies. To compare pre- and post-intervention vaccinations, HPV vaccination data were extracted from an electronic medical record request for age-eligible patients seen in the practice during the intervention year. Chi-square, McNemar's and 2-tailed, 2-sample Z tests were used to test differences in vaccination initiation (≥1 dose) and completion (3 doses) across groups and over time. RESULTS: Despite high pre-intervention rates (58% and 75%), HPV vaccine initiation significantly increased 12.8 percentage points (PP) for males and 10.6 PP for females from pre- to post-intervention (P < 0.001). HPV vaccine completion also significantly increased 16 PP for males and 10.9 PP for females (P < 0.001). Young adult patients (18-26 years-old) had significant increases in completion rates (9.9 PP; P < 0.001), not observed among adolescents (20 PP; ns). CONCLUSIONS: Consistent and abundant positive HPV vaccination messaging, low-cost sensory rewards, process change, and community, clinician, and nonclinical staff engagement were associated with higher HPV vaccine initiation and completion, especially among young adults.
