Quality Improvement Project to Increase Human Papillomavirus Two-Dose Vaccine Series Completion by 13 Years in Pediatric Primary Care Clinics

The human papillomavirus (HPV) causes genitourinary and oropharyngeal cancers. The HPV vaccine is safe and effective in preventing those diseases; however, vaccine series completion rates remain low in the United States. Our quality improvement (QI) project aimed to increase HPV-vaccination series completion rates to 70% from 2017 to 2020 for the 13-year patient population in an extensive academic pediatric primary care network that serves predominantly minority and Medicaid-insured children in Columbus, OH. The outcome measure was the percentage of 13-years Nationwide Children's Hospital Primary Care Network patients who completed the two-dose vaccine series by their 13th birthday. Four QI implemented interventions were utilized. Electronic medical records alert informed providers when the HPV vaccines are due. We studied monthly data for the network and for individual clinics using statistical process control, displaying data on a control chart. We followed two process measures, captured opportunity rate, and the number of HPV vaccines given. We substantially increased HPV-vaccination series completion rates overall in the 13-year teen population from 27% to 65%, and three clinics reached the 70% goal for at least one quarter. Latino children had the highest completion rate of 80% and White children had the lowest completion rate at 64%. Our QI project used four measures to improve HPV-vaccination series completion rates in the 13-year patient population that serves minority and low-income teens predominantly. Further QI studies are needed to improve HPV vaccine completion rates in teens.
