The island situation of the CHM, the only health establishment in the department, makes it a central player in the health response to exceptional situations. The particularity of the territory subject to climatic, epidemic and seismic risks in particular must be taken into account in emergency plans. Thus, the CHM needs to equip itself more in order not only to meet the daily need for patient care but also to cope with any crisis, be it health or climate. The project to upgrade and adapt the technical platform provides a response allowing the CHM to gain more autonomy and increase the diagnostic and management capabilities of patients.
