Abstract

Background: The COVID-19 pandemic, and vaccine hesitancy, pose a significant public health threat. The Veterans Health Administration system is uniquely situated to provide insights into the implementation of a population health approach to vaccine acceptance.

Aim: We describe the VA Connecticut Healthcare System's (VACHS) quality improvement project to improve rates of vaccine uptake.

Setting and participants: VACHS consists of eight primary care sites with 80 primary care providers delivering care to 47,000 enrolled veterans.

Program description: Our program involved identification of a local champion, education sessions, development of vaccine acceptance tools (including the templated "COVID-19 Prevention Letter" and the "COVID-19 Prevention Telephone Note"), and application of a population health approach (use of a prioritization scheme and playbook) by primary care patient-aligned care (PACT) medical home teams.

Program evaluation: We found increased rates of vaccination at VACT compared to the surrounding region 6 months after implementation (65.16% vs 61.89%). Use of vaccine acceptance tools were associated with a statistically significant increase in vaccination (24.1% vs 13.6%, P = 0.036) in unvaccinated veterans.

Discussion: A population health approach to vaccine acceptance using EHR-based tools can impact vaccination rates, and this approach may be of practical utility to other large healthcare systems with EHR.
