ABSTRACT
BACKGROUND: The American Cancer Society and the American Academy of Pediatrics recommend administering the human papillomavirus (HPV) vaccine to children aged 9 and 10 years to improve on-time vaccination rates as they continue to be below national goal. Pharmacist-led interventions using the electronic health record (EHR) may be an effective way to increase these rates. OBJECTIVE: This study aimed to evaluate change in first-dose HPV vaccination rate in 9- and 10-year-olds before and after a multifaceted HPV outreach initiative. METHODS: A pre-post, quasi-experimental study involving a pharmacist-led intervention was implemented at 2 primary care offices within a large health care network. Adolescents aged 9 and 10 years during the entire intervention period were included. Between November 1, 2021, and March 31, 2022, an education session was provided by an ambulatory care pharmacist to each primary care team regarding the HPV vaccine and eligibility of 9- and 10-year-olds. On June 1, 2022, a direct message was sent via the EHR to parents or guardians of eligible patients describing eligibility, risks and benefits, and best practice recommendations. The primary end point evaluated change in first-dose HPV vaccination rates in 9- and 10-year-olds measured 6 months after direct messaging. Secondary outcomes evaluated EHR message receipt, adverse events, and program revenue. Nominal outcomes were assessed with McNemar's test or Cochran's Q test using SPSS software; P < 0.05 was considered significant. RESULTS: A total of 367 patients aged 9 and 10 years were eligible for HPV vaccination. After the intervention, 45 patients were vaccinated with vaccination rate increasing from 0.5% to 12.8% (P < 0.001). A total of 288 (78.5%) had access to EHR messaging with 203 (55.3%) having confirmed receipt of the message. No adverse reactions were reported within 7 days of vaccination. Most patients (76%) had private insurance, followed by Medicaid (22.6%) and uninsured (1.4%). Approximate revenue of the program was $4129.89. CONCLUSIONS: A multifaceted intervention using education and EHR direct messaging significantly increased HPV vaccination rates in 9-and-10-year-olds.
