Zest Co., Ltd. (Headquarters: Shinjuku-ku, Tokyo; Representative Director and CEO: Junnosuke Isshiki) announced that it has implemented a new update to "ZEST HUB," its dedicated smartphone and tablet app for "ZEST," a revenue improvement platform for home medical and nursing care.
This update adds a "push notification feature" for frontline staff and an "in-app cancellation processing and reason visualization feature." This will further reduce the burden of communication tasks for frontline staff and provide a strong foundation for management to accurately grasp the operational status of their facilities and the factors causing opportunity loss, thereby leading to revenue improvement.

■ Background of the Update and Business Impact of New Features
In the field of home medical and nursing care, schedule changes on the day are commonplace due to changes in the user's condition. While "ZEST" has promoted operational efficiency through automatic visit schedule creation and LINE WORKS integration, we have developed the following two new features to achieve further "revenue maximization" and "stable operation" for facilities.
① "Push Notification Feature" Dramatically Reducing Communication Workload (※iOS version only)
【Use Case: Freedom from phone calls and memos for every change】
Previously, whenever a schedule change occurred, administrators had to contact the responsible staff by phone or verbally, which put pressure on their busy schedules. It was often difficult to reach staff while driving, and there was always a risk of "he said, she said" disputes or missed visits.
【Contribution to Management and Frontline】 With this feature, when an administrator changes a schedule on the system, a push notification will automatically be sent to the staff's "ZEST HUB" app. Even facilities that have not introduced external business chat tools like "LINE WORKS" can ensure staff are reliably informed of changes on their own devices. Of course, detailed settings are possible, such as not receiving notifications for unconfirmed appointments or schedule changes other than user visits. This reduces the enormous hidden costs (personnel expenses, time) associated with administrators' communication tasks and prevents the critical risk of staff forgetting visits through the system, thereby building a reliable service provision system that protects the safety and security of users.
※ The push notification feature is currently only available for iOS (iPhone, iPad) app versions.
② "Cancellation and Reason Visualization Feature" to Capture Hints for Improving Utilization Rates
【Use Case: Prompt processing and data accumulation of sudden cancellations on site】
In home care, cancellations due to user circumstances, such as sudden illness or urgent short-term stays, occur frequently. Previously, when frontline staff received a cancellation, there were cases where reporting was delayed until they returned to the office, or schedule updates were slow. As a result, the number of visits could differ significantly from expectations at the billing stage. Furthermore, without visible cancellations, it was difficult to identify the cause and action, such as whether efforts to increase visits were insufficient or if mechanisms to prevent visit reductions were lacking.
【Contribution to Management and Frontline】 With this update, frontline staff can set schedule cancellations and reasons from the mobile app at any time. The management dashboard "ZEST BOARD" allows for detailed analysis of how many cancellations occurred for what reasons and their breakdown. This enables actions such as rescheduling to ensure necessary care is delivered without delay or reviewing the system. By making "the volume and factors of opportunity loss" visible to management, it directly contributes to solving the most critical management challenge of "improving utilization rates" by analyzing common cancellation trends to review excessive staffing or quickly assigning other visits to sudden open slots.

■ Future Outlook

We will continue to address real-world challenges on the ground and expand our functions to become an indispensable infrastructure for both management and frontline staff.
