Looped Audiovisual Health Education Talk Reduces Vaccine Clinic Wait Time in Nigeria

Wait time at vaccine clinics is a barrier to routine childhood vaccinations in low- and middle-income countries (LMICs). Waiting for a critical mass of clients to accrue before conducting the vaccine health education talk prolongs clinic time.

We implemented a workflow change, including a looped audiovisual vaccine education talk on a solar-powered television. We compared clients' average clinic time using a before-and-after study, time-motion design, and surveyed providers and clients on their perspectives on the workflow change.

In the post-implementation phase, compared to the pre-implementation phase, the average clinic time for all clients and the subgroup who presented before 9:00 AM was significantly reduced by 13 and 31 min, respectively (p = 0.006 and < 0.000). Providers and clients were positive about the workflow change.

A looped audiovisual vaccine education talk significantly reduces client vaccine clinic wait time and is acceptable to providers. Research on the impact of workflow change with alternate vaccine health talk delivery mode on vaccine uptake and completion is required.
