Prime Clinic Mitaka, operated by the medical corporation Shinkai Medical Association, is an internal medicine clinic located in Shimorenju, Mitaka City, Tokyo, specializing in home-visit medical care for patients who have difficulty attending outpatient appointments. The clinic's most notable feature is its team of 22 specialists with experience in home healthcare, covering 15 medical departments including cardiology, gastroenterology, pulmonology, neurology, psychiatry, and palliative pain management. While regular visits approximately twice a month serve as the standard, the clinic can arrange a customized care plan based on the preferences of patients and their families, aiming to provide home-based medical care comparable in scope to that of a general hospital. A wide range of tests can be performed at home, including electrocardiograms, ultrasound examinations, and blood tests, and the clinic also handles procedures such as gastrostomy tube management, home oxygen therapy, and cancer pain management. In the event that a patient under home-visit care experiences a sudden change in condition on an unscheduled day, the clinic provides telephone support and emergency home visits 24 hours a day, 365 days a year, and can arrange hospital admission at a partner medical institution if necessary. The clinic serves patients in serious conditions such as bedridden patients, those with dementia, terminal cancer, and intractable neurological diseases, and covers an area of approximately 16 km around Mitaka City, providing comprehensive support for home-based recuperation.
