PHE happens suddenly and its incidence rate is relatively low, which leaves most medical staff inexperienced and unprepared [11] . Therefore, it is important that hospitals develop emergency plans for PHE treatment programs. In this survey, more than half of respondents showed that their physicians were aware of current PHE protocols. Most hospitals had transfer and treating procedures for infectious diseases, including SARS, influenza, and infectious diarrhea, but less held these procedures for biochemical incidents, leakage of nuclear, and terrorist attacks. Because they are easily used as biological terrorist attacks materials [20] , therefore, the prevention and control of these emergencies become very important. Our statistical analyses showed that tertiary-grade, teaching and TCM-WM hospitals performed better on medical treatment procedures preparedness, which might reflect the fact that different types of hospitals have different functions and mission in the community, however, for this capacity, the statistical significance among different regions showed the important role that economic factor plays.
