Separability disorder is also called hysteria, and its main manifestations are separation symptoms and conversion symptoms. Patients often have symptoms such as acute stress disorder and traumatic stress disorder. Infectious public health emergencies are unpredictable and have a wide range of impacts. In such cases, nurses are faced with intensive work, and their mental health is greatly damaged. What’s more, it will cause psychological diseases such as acute stress disorder and traumatic stress disorder. Therefore, it is necessary to organize psychological experts to form intervention teams and establish perfect intervention procedures so as to pay attention to the psychological health of nursing staff and to track and evaluate their psychological status.

The experiment randomly selected 46 nursing staff with dissociative disorder in sudden public health events, and divided them into an experimental group (23) and a control group (23). The patients in the observation group were given routine nursing care, and the experimental group added a team of psychological experts to intervene on this basis. During the intervention, attention should be paid to the construction of a good atmosphere and the maintenance of indoor lighting, temperature, humidity, and another comfortable physical environment. After 2 months of the experiment, the SAS and SDS scores of the two groups were observed.

Table 1 shows the comparison of SAS (Self-Rating Anxiety Scale) scores and SDS (Self-Rating Depression Scale) scores of patients with dissociative disorder in two groups of public health emergencies before and after the intervention. Before the intervention, there was no significant difference between the two groups (P > 0.05). After the intervention of the psychological experts, the scores of the two groups decreased, indicating that the patient’s condition had improved. However, the psychological status of patients in the experimental group was significantly better than that in the control group, and the difference was statistically significant (P < 0.05).Table 1.

Nursing staff in public health emergencies are prone to suffer from separation disorder due to the particularity of their occupation. Therefore, based on the topic of psychological health of nursing staff, the experiment proposed the method of establishing a team of psychological experts to intervene in the psychological health of front-line nursing staff. The final experimental results show that this method can indeed improve the probability of separation disorder among nursing staff.
