A simple system for calling patients, "One-Touch Call."

We have introduced the "One-Touch Call" calling bell at the Health and Welfare Center in Yamatsuri Town, Fukushima Prefecture. At the mass vaccination site for the novel coronavirus, when the waiting room becomes full, we provide the calling bell so that people can wait in the parking lot until their turn. "It allowed for smooth handling by giving the calling bell to those who wanted to wait outside or when the waiting room was full." "Older adults can simply return when the calling bell rings, so everything proceeded without any issues." This has received positive feedback. To use it, we hand the "One-Touch Call receiver" to those waiting at the reception, and when their turn comes, we press the "One-Touch Call transmitter," prompting the vaccine recipient to return to the reception to collect the "One-Touch Call receiver." The calling bell, familiar from food courts, is a simple device that is easy to understand and use for everyone, without requiring older adults to engage in tasks like "registering as a member via smartphone" or "scanning QR codes," which they may not be familiar with. The venue staff can also proceed smoothly without needing to explain operations or answer questions. This helps prevent difficulties in communication and understanding the situation due to crowding.
