Objective  To analyze Chinese national laws and regulations on emergencies from the perspective of nursing and on the basis of the crisis life cycle theory, to discuss the weaknesses in laws and regulations concerning emergencies, and to provide evidence for the definition of the scope of disaster nursing practice in China.

  Methods  We selected emergency laws and regulations promulgated by the National People's Congress and its Standing Committee and the State Council as the subject matter of the study, constructing the analysis framework on the basis of the core competence of disaster nursing and crisis life cycle theory. Then, the 16 laws and regulations included in the study were analyzed with NVivo 12 software by the content analysis method.

  Results  A total of 6 laws and regulations concerning earthquakes, 3 concerning infectious diseases, 2 concerning fire, 2 concerning food poisoning, 2 concerning emergencies, and 1 concerning flood were selected. A total of 24 food poisoning-related codes, 23 infectious disease codes, 22 emergency event codes, 22 earthquake codes, 21 fire codes, and 16 flood codes were obtained. In the key links of emergency preparedness, early prevention had the highest number of reference points, whereas collaborative response had the lowest number of reference points. In the key processes of emergency preparedness, aftermath management had the highest number of reference points, whereas social services and continuous operation had the lowest numbers of reference points.

  Conclusion  Laws and regulations concerning emergencies are generally formulated on the basis of certain historical experience, with collaborative response, social services, and continuous operation being the weak links and processes. In the process of disaster nursing practice, we should effectively make up for the weaknesses in laws and regulations concerning emergencies by utilizing the positive aspects and the essence of the discipline.
