MMWIN (Miyagi Medical and Welfare Information Network) is a secure data sharing network for hospital information systems. The network allows for clinical data from a hospital’s information system to be transferred into SS-MIX2-formatted XML/HL7 files. A data center is connected to the MMWIN server through a secure virtual private network (VPN).

Miyagi Medical and Welfare Information Network (MMWIN)

The Miyagi Medical and Welfare Information Network (mmwin) was launched in 2013. This network allows medical facilities in the Miyagi Prefecture to save and share patient data. These medical facilities may use the data to diagnose and treat patients, such as patients who have received dialysis.

The Miyagi Medical and Welfare Information Network, a health information exchange network, was established after the Great East Japan Earthquake hit the country in 2011. In the aftermath of the disaster, a number of medical facilities were destroyed, including hospitals and clinics. The disaster resulted in the loss of patient medical records. Because of this, backup systems were put into place.

The MMWIN system connects computers in affiliated facilities to a central server. This server transmits clinical data from the hospital information system to SS-MIX2-formatted XML/HL7 files.

Data center

Miyagi Medical and Welfare Information Network (MMWIN) and SS-MIX2 are two standards that are used to standardize medical information. Both of these standards provide enhanced security and reliability. This data center will help MMWIN and SS-MIX2 users share and store medical records.

The MMWIN data center uses a secure network that connects the computer systems of participating medical facilities to the MMWIN servers. Clinical data from the hospital information system is then transferred to SS-MIX2-format XML/HL7 files and stored on the MMWIN data center’s server.

Disasters can disrupt a healthcare system and cause lost records. In 2012, the Miyagi Medical and Welfare Information Network (MMWIN) launched a disaster-resilient data storage service. This service has since backed up the medical information of over 12 million people. In this talk, Dr. Masaharu Nakayama, Professor of Medical Informatics at the Tohoku University School of Medicine, will discuss the project’s advantages and challenges.

Hemodialysis report

The MMWIN Hemodialysis report is a medical record that provides information about dialysis treatments. The report is a format that is compatible with the SS-MIX2 format. The data can be transferred automatically from a dialysis machine to the MMWIN SS-MIX2 center. Alternatively, the data can be transferred manually via a document sharing system.

Hemodialysis patients require a team approach to their care. They often have multiple comorbidities and require a range of specialist expertise. Sharing clinical information among facilities is not always easy. Most hospitals and dialysis clinics do not use the same electronic health record (EHR) or health information exchange (HIE) system. In addition, they rarely integrate their systems. This fragmentation of clinical information can make disaster preparedness extremely difficult.

Dialysis is often performed for a short period to replace lost kidney function. However, this procedure may have some risks, and is not suitable for every person. In some cases, patients may need hemodialysis for a longer period of time. In these cases, a preemptive kidney transplant may be an option. In other cases, the patient’s condition may require more frequent or intense treatment. Ultimately, the care team will determine whether or not to continue hemodialysis.

SS-MIX2 extension storage

The MMWIN SS-MIX2 expansion storage allows healthcare facilities to store clinical data in a secure location. The system uses a virtual private network to connect all computers within a facility to a single centralized server. These computers transmit clinical data from the hospital’s information system to the MMWIN server, which then converts it to SS-MIX2 files.

The MMWIN system consists of a portal server for patient ID registration, an SS-MIX2-format storage server, and backup storage. In addition, MMWIN includes a gateway, which receives and stores clinical data from facilities. SS-MIX2 is a medical information exchange standard authorized by the Ministry of Health, Labour, and Welfare of Japan (MHLW). It enables collection of clinical information from various vendor systems. Currently, SS-MIX2 is used in several national projects in Japan.

SS-MIX2 is an XML/HL7 file format that is used to store medical information. This file format supports a hierarchical tree structure and is structured for optimal retrieval of clinical data. The SS-MIX2 viewer application, which is browser-based, can retrieve MMWIN data. Fujitsu has developed an application, Human Bridge, which enables clinicians to review clinical data from SS-MIX2 storage.
