[EMI net--electronic medical record sharing in local community for home care medicine].

An electronic medical information network (EMI net) includes patient records from more than 40 facilities in Matsudo City and it is now used especially to improve the communication between doctors and nurses who visit patients' homes. This fact suggests the importance of a medical information sharing system in a local area for home care medicine. An infrastructure connecting facilities to share the database of the patient records is essential for home care medicine performed by a multidisciplinary team beyond one medical facility.
