Features of the On-Call Substitute Service "ON CALL" for Home Medical Care Institutions
We respect the treatment policies of medical institutions and the wishes of patients, and achieve high-quality on-call substitution through the following three pillars.
Adoption of a "Referral System" Centered on Physicians from Acute Care Hospitals
Our affiliated physicians are mainly those active on the front lines at university hospitals, emergency critical care centers, etc. We thoroughly implement a "referral system" where new members are recruited solely through referrals from existing members. We have assembled a reliable team possessing not only medical expertise but also the "personality" and "communication skills" essential for home healthcare.
"Two-Person System" and "Collaboration System" to Ensure Physician Quality
We visit with a mandatory two-person team consisting of a physician and a home visit director, providing high-quality medical care from on-site treatment to family care. Furthermore, by utilizing our proprietary system, we share detailed medical records and handover information the following morning, reliably passing the baton to the primary physician.
Functionality as a Regional Medical Resource
By providing nighttime and holiday coverage on a spot basis, we eliminate gaps in regional medical care and contribute to the optimization of emergency transport and support for end-of-life care at home.
