Research on the individualized short‐term training model of nurses in emergency isolation wards during the outbreak of COVID‐19

To explore an effective personalized training model for nurses working in emergency isolation wards of COVID‐19 in a short period.

transmission routes (National Health Commission of China). COVID-19 broke out in Wuhan in December 2019, and then, the epidemic spread globally (WHO, 2020). The whole world should pay attention to how to deal with the outbreak (Kickbusch & Leung, 2020). To stop the spread of the epidemic as soon as possible, all of provinces and cities in China have taken strong measures. Although various industries have resumed production in China, the current international COVID-19 epidemic is still grim. Under this circumstance, how to control the epidemic situation and prevent the recurrence of the COVID-19 epidemic is worthy of attention (Wu, Guo, & Chao, 2020).
Through literature review, there are many studies on COVID-19 in various countries; however, there are few reports about the training content of the nurses in the emergency isolation ward. Our training methods follows the model: training → assessment → feedback → evaluation → retraining → reassessment. Hopefully, this study could provide theoretical basis for training nurses under emergency assistance of COVID-19 and we also hope to work with nursing colleagues around the world with an open attitude to save more patients.

| Background
The Sichuan Provincial People's Hospital has temporarily established an emergency isolation ward during the outbreak of COVID-19. To seek efficient nursing training mode under the epidemic situation and improve the nurses' knowledge reserve on emergency handling and control capabilities, a combination of on-site training and online training was implemented to provide COVID-19 related knowledge on nursing operation skills and hospital infections to the nursing team in a short term. The medical department, the infection control department and the nursing department trained the nursing staff through online social media (WeChat or OA system) and on-site training. The nursing operations are mainly conducted through onsite training. All nursing staff need to pass the assessment before they start to work in the emergency isolation ward. The electronic questionnaire was filled in after the nursing staff worked in the ward for 2 weeks to assess the nurses' need for training. Then, targeted training was conducted and the training results were evaluated by trainers.

| Reconstruction of emergency isolation wards
To control the spread of the epidemic, cut-off the route of transmission and protect susceptible cases effectively, Sichuan Provincial People's Hospital reconstructed emergency isolation ward within three days. There are 32 open beds in this ward. By the end of 28 February (2020), a total of 111 suspected patients were treated in the emergency isolation ward, including three patients who were diagnosed with COVID-19. They are mainly middle-aged and elderly patients.

| Preparation and management of the nursing team
During the preparation of the emergency isolation ward, the nursing department established the logistics team, professional team and management team immediately. The logistics team is responsible for participating in ward reconstruction and material preparation; the professional team is responsible for personnel training and supervision; and the management team is responsible for nursing staff management, including communication and coordination among various departments.
Firstly, the management team established a human resource database for emergency isolation ward. All nurses in the hospital are encouraged to apply online to the human resources database. Then, 71 nurses were selected by the nursing department from the human resources database. To avoid excessive fatigue, the selected nurses are divided into three echelons and work in turns on a flexible schedule. Nursing positions included clinical nurses, supervisors, trainers and head nurses.

| Nursing staff training
The training process adopts training → assessment → feedback → evaluation → retraining → reassessment. A scenario drill is added in the first operation training section.
The training forms and content are shown in Table 1. The forms are including online training and on-site training. The training contents include basic diagnosis, hospital infection, operation and psychological support.

| Disaster psychological knowledge training
Previous studies have already shown that nursing staff working in the emergency isolation wards might face tremendous psychological pressures (Oh et al., 2017). The anxiety self-rating scale (SAS) and depression self-rating scale (SDS) were implemented by head nurses to evaluate the psychological status of nursing staff.
Psychologists provide psychological support and guidance to medical staff based on individual circumstances, including online and on-site psychological counselling (Zhou, 2020). In addition, experts from the psychological workshop were invited to perform mindfulness decompression. Psychological intervention based on mindfulness meditation has become an increasingly obvious part of the healthcare field (Demarzo, Cebolla, & Garcia-Campayo, 2015).

| Evaluation tool
Evaluation indicators include the following: nurses' grasp of training content, choice of training methods and improvement of psychological conditions before and after training. A self-made online questionnaire "Nursing Staff Emergency Training Mode Approval Feedback Questionnaire" was used to access nursing staff's feedback on the emergency isolation ward's training mode. The questionnaire is divided into four parts and 20 items which mainly includes basic information, feedback on theory, operation training methods and content.
In order to evaluate the degree of recognition, the training content evaluation is divided into three angles: text, graphics and video.
The knowledge level of the COVID-19 is based on the National Health and Health Commission's diagnosis and treatment plan and the hospital's sense prevention and control requirements, including theory and operation. The "Nursing staff COVID-19 emergency training theory assessment test questions" is prepared for online assessment. The operation technology is on-site assessment. Then, comparing the pre-training and post-training, nursing theory and operation score are proportional to the degree of knowledge mastery.
The improvement of nursing staff's psychological construction level before and after the training adopts Zung's (1971) self-rating anxiety scale (SRAS) and Zung's (1965) self-rating depression scale (SRDS).
Zung's SRAS and SRDS consist of 20 questions, each of which has answers in Likert scale format from levels 1-4. The original score is converted to 100 points and psychological evaluation of the nursing staff is performed. The higher the score, the greater the degree of anxiety and depression. Comparison was made before and after training.

| Statistics
Statistical analysis was performed by SPSS13.0 software. Normal continuous variables were expressed as mean ± standard deviation, non-normal continuous variables were expressed as median values (interquartile range) and categorical variables were expressed as percentages. The comparison between groups was based on whether they met the normal distribution using the Mann-Whitney U test or t test and the categorical variables used the chi-square test or Fisher's exact test. Before and after the training, paired t test is mainly used; p < .05 was considered statistically significant.

| Ethical considerations
The study was previously explained to the head nurse of the selected hospital, with official permission. The purpose of the study was explained to all study participants, and their informed consent was subsequently obtained. All answers are confidential and used for this study only.

| RE SULTS
Basic information of nursing staff. It is shown in Table 2  and there were also nine staff whose working experience was under 5 years (12.68%). There were 36 internal nurses, accounting for 50.7%, 23 surgical nurses, accounting for 32.39% and six paediatric and obstetrics nurses, accounting for 8.45%. The mean age of nurses was 31.31 (SD 4.85), their working years ranged from 2 to 20 years.

| Nursing staff's degree of recognition of training method
Through the scale survey of nurses' degree of recognition of training methods, the results have shown that theoretical training, environmental and process training using online and offline combination (online + on-site training) method is better Statistical significance (p = .042, p = .002); while the operation training adopts on-site and on-site + network training methods, the difference is not significant.

| Nursing staff's recognition of the training content
Nursing staff recognized and evaluated the training content in the form of questionnaires in terms of text, graphics and video. It is indicated that the operation training content with partial text and video was better (p = .042, p = .040). There is no difference in the training effect of the three types of network training content, theoretical training, environment and process training (Table 4).
Compared with pre-training and post-training, the improvement of the COVID-19 theory knowledge, operation skills and psychological conditions was significantly improved by paired t test, the mean value is >0 and the p value is <.01. The SAS score decreased after training, with statistical difference (p = .019). The difference in SDS before and after training was not statistically significant, with a pvalue equal to .306 (Table 5).

| Nursing staff's understanding of COVID-19 related theory
This study has shown that compared with the pre-training, the dif- In terms of the degree of recognition of the training content, the results of this study have shown that the order of online training scoring is as follows: online video, online text and online graphics.
It illustrates that dynamic visualization training works best. And dynamic visualization training, such as animation and video, has been proved as a particularly effective teaching programme (Bernay & Betrancourt, 2016;Betrancourt & Tversky, 2000;Marcus, Cleary, Wong, & Ayres, 2013).
Regarding the selection of training methods, the results of the study have revealed that the on-site training method is effective for the nursing staff to improve their ability in emergencies, and the combination of network and on-site training methods is the best.
Supported by research, the comparison between online and faceto-face training, well-designed online training shows more advantages in terms of time efficiency and memory effect (Kalyuga, 2007; TA B L E 5 Before and after training, the nursing staff improved the COVID-19 theory knowledge, operation skills and psychological conditions Kalyuga & Sweller, 2005), which is consistent with the results of this study. But it is less effective at changing behaviours (Aspegren, 1999;Mansouri & Lockyer, 2007) and face-to-face training seems to be more effective than online training. The reason for analysis may be related to the knowledge and skills provided by online training, and the on-site training can improve the self-confidence of nursing staff.
The psychological status of nursing staff before and after working in the emergency isolation ward.
The results of this study showed that the SAS score of nursing staff after standardized training was lower than before training (p < .05). It indicates that through training and psychological intervention (mindfulness, group) related to the COVID-19, the nurses in the emergency ward can be guided to scientifically treat the infection and control of the COVID-19, thereby reducing the level of anxiety. The SDS level did not change much before and after, one of the possible reasons could be the short-term trainees did not reach the level of depression. However, although the training involves psychological aspect, the need for psychological support is repeatedly mentioned in the questionnaire, indicating that when the medical staff first contacted the patient at the beginning of the outbreak and faced a large number of patients (Suwantarat & Apisarnthanarack, 2015), the nurse's level of occupational stress is increasing. (Wheeler, 1997).

| Limitations
Due to the short-term emergency training and the high risk of infection, it is a huge challenge work for nursing staff. The survey shows that psychological problems are repeatedly mentioned, indicating that nurses have a greater need for psychological support, which seemingly suggests that future psychological support for front-line nurses needs to be strengthened in many ways (Zhou, 2020).
Selecting the nursing staff of the emergency ward of a hospital may have certain geographical restrictions, or the sample size may not be large enough. More samples from different regions can be researched in the future.
The theory of planned behaviour holds that past experience is one of the determinants of a person's beliefs (Ajzen, 1991;Oh et al., 2017). The planned selection of experienced nursing staff to participate in the rescue incident is more conducive to the rescue work. This training did not involve the problems of personnel's previous rescue experience. In future emergency rescue work, it is preferable to choose personnel with rescue experience in the human resources database.

| CON CLUS ION
Emergency training of nursing staff is crucial on preventing the spread of the COVID-19 epidemic effectively and ensuring the operation of emergency isolation ward orderly. The training content of this study is based on the COVID-19 Theory operating materials of the Chinese Health Commission and the US guidelines for disease prevention. The training form is a combination of online and offline.
In order to form the best training content and provide an optimized training model for the next epidemic prevention and control, the effectiveness of the training form was analysed. At the same time, this study pays particular attention to the psychological problems of nursing staff. Carrying out the prevention and intervention of psychological problems to the nursing staff in a timely manner will ensure the staff positively faces the epidemic situation. In short, the value of nursing staff in the prevention and control of the COVID-19 epidemic cannot be replaced. How to ensure the safety of nursing staff and patients through training is a significant issue that worth to be discussed.
