Clinician Prompts for Human Papillomavirus Vaccination: A Cluster Randomized Trial.

Objective: We assessed the impact of an online intervention using clinician prompts for human papillomavirus (HPV) vaccination with a cluster randomized controlled trial.
Methods: The randomized trial occurred July 2021-January 2022 in 48 primary care pediatric practices (24 intervention, 24 control) across the US. We trained clinicians via two online learning modules, plus weekly ''quick tips'' delivered via text or email. The training taught practices to implement a staff prompt to the clinician (e.g., printed reminders placed on the keyboard) plus electronic health record (EHR) prompts (if not already done) at well and acute/chronic visits for initial and subsequent HPV vaccination. We assessed missed opportunities for HPV vaccination using logistic regression models accounting for clustering by practice on an intent to treat basis. Surveys assessed facilitators and barriers to using prompts.
Results: During the 6-month intervention, missed opportunities for HPV vaccination increased (worsened) in both intervention and control groups. However, at well child care visits, missed opportunities for the initial HPV vaccine increased by 4.5 (95% CI: -9.0%, -0.1%) percentage points less in intervention versus control practices. Change in missed opportunities for subsequent doses at well child care and non-well child care visits did not differ between trial groups. An end-of trial survey found understaffing as a common challenge.
Conclusions: Clinician prompts reduced missed opportunities for HPV vaccination at well child care visits. Understaffing related to the COVID-19 pandemic may have led to worsening missed opportunities for both groups and likely impeded practices in fully implementing changes.
