Background and Purpose of the Relocation

Our "ON CALL" service has earned deep trust from medical institutions supporting local home healthcare, recording an annual growth rate exceeding 200%.

Accompanying this growth, the number of our headquarters operational members, including call center staff (nurses) who serve as a hub during nights and holidays, and the support team that daily assists medical institutions, has significantly expanded.

The purpose of this office relocation is to enhance these headquarters functions and strengthen our system for further improving service quality. By strengthening cooperation between field and headquarters members, we aim to serve as a base that can provide even more prompt and high-quality medical support, fulfilling an infrastructure role in filling the gaps in regional medical care.

Features of "ON CALL," a Visiting Medical Service Proxy for Home Medical Institutions

We respect the medical institutions' treatment policies and patients' wishes, and achieve high-quality on-call proxy services through the following three pillars:

Adoption of a "Referral System" centered on doctors from acute care hospitals

Our affiliated doctors are primarily those active on the front lines, such as university hospitals and emergency medical centers. We strictly adhere to a "referral system" where recruitment is only through existing members. We form a reliable team equipped not only with medical skills but also with the "personality" and "communication abilities" essential for home medical care.

"Two-person System" and "Coordination System" to ensure doctor quality

Doctors and visiting directors always visit in a two-person team, providing high-quality medical care from on-site treatment to family care. Furthermore, utilizing our proprietary system, detailed medical records and handover instructions are shared by the next morning, ensuring a smooth handover to the primary physician.

Function as a regional medical resource

By handling night and holiday responses on a spot basis, we eliminate gaps in regional medical care and contribute to the optimization of emergency transport and support for home-based end-of-life care.
