The Software was successfully developed as a new Integrated of Medical Information System in Disaster Reduction and beta testing has been carried out by programmers, doctors, and lecturers from Disaster Medical discipline. The software appeared to be in running order and functional but also deemed to need further field test runs by officers facing real-life disaster events. Conclusions and Recommendations, is a Medical Information System for Disaster Risk Reduction has been developed and consists of 3 software modules for Training students and professional.
