Objective To study the method of modularized medical supplies for PTSD under the medical rescue supply system. Methods The incidence of PTSD during varied disasters was determined using literature search. Then the number of subjected populations, rescue soldiers and basic units, the rescue time, and the item and quantity criteria for medical materials and demand of every 100 soldiers were established. According to the incidence of PTSD during varied disasters ，the medical supply system was generated for the prevention and treatment of PTSD .Results The incidence of PTSD varies from disaster to disaster, and we can establish the item and quantity criteria for medical materials and demand of every 100 soldiers during different disasters with the medical rescue supply system. Conclusion Modularization of medical supplies is available, which may offer an effective pathway for medical supplies used for the prevention and treatment of PTSD in the course of disaster relief.
