A Multicomponent Strategy to Increase Human Papillomavirus Vaccination Rates in Primary Care: A Cluster Randomized...

Area of Science:

• Public Health
• Preventive Medicine
• Pediatrics

Background:

• Human papillomavirus (HPV) vaccination is crucial for preventing HPV-related cancers.
• Current HPV vaccination rates in primary care settings fall below national targets.
• There is a need to evaluate strategies to improve timely HPV vaccination.

Purpose of the Study:

• To assess the effectiveness of a multicomponent intervention aimed at increasing HPV vaccination initiation and completion by age 13.
• To determine if a combined strategy of practice facilitation, audit and feedback, education, and communication can improve HPV vaccination uptake.

Main Methods:

• A cluster randomized clinical trial involving 20 primary care pediatric practices.
• Intervention included practice facilitation, audit/feedback, education, and communication strategies over 24 months.
• Primary outcomes measured HPV vaccination initiation and completion by age 13, assessed at 24 and 36 months.

Main Results:

• No significant differences in HPV vaccination initiation or completion rates were observed between the intervention and control groups at 24 months.
• At 36 months, initiation rates were 82.0% (intervention) vs 74.6% (control), and completion rates were 57.8% vs 49.9%, respectively.
• While overall differences were not significant, intervention effects for vaccination initiation showed a statistically significant increase over time (P=.04).

Conclusions:

• The tested multicomponent intervention did not significantly improve HPV vaccination rates by age 13 in the evaluated timeframe.
• The observed trend of increasing intervention effects over time suggests that system-focused strategies may require longer evaluation periods.
• Further research may explore optimizing intervention components or duration for sustained impact on adolescent vaccination.
