Aim: To investigate the prevalence of insomnia among front-line nurses fighting against COVID-19 in Wuhan, China, and analyse its influencing factors. Background: Insomnia is an important factor that can affect the health and work quality of nurses. However, there is a lack of big-sample studies exploring factors that affect the insomnia of nurses fighting against COVID-19. Method: This cross-sectional study using the Ascension Insomnia Scale, Fatigue Scale-14 and Perceived Stress Scale took place in March 2020. Participants were 1,794 front-line nurses from four tertiary-level general hospitals. Results: The prevalence of insomnia among participants was 52.8%. Insomnia was predicted by gender, working experience, chronic diseases, midday nap duration, direct participation in the rescue of patients with COVID-19, frequency of night shifts, professional psychological assistance during the pandemic, negative experiences (such as family, friends or colleagues being seriously ill or dying due to COVID-19), the degree of fear of COVID-19, fatigue and perceived stress. Conclusion: The level of insomnia among participants was higher than the normal level. Interventions based on influencing factors should be implemented to ensure nurses' sleep quality. Implications for Nursing Management: An in-depth understanding of the influencing factors of insomnia among front-line nurses can help nurse managers develop solutions to improve front-line nurses' sleep quality, which will enhance the physical and mental conditions of nurses and promote the quality of care.

Aims and Objectives To investigate the present status of anxiety among nurses fighting the spread of COVID‐19 and its association with perceived stress and insomnia. Background With the outbreak of COVID‐19, nurses have been caring for infected patients for a considerable length of time in Wuhan, China. Previous COVID‐19 studies generally focused on patients’ medical treatment, but few considered healthcare workers’ psychological needs while working with a pandemic involving an unfamiliar infectious disease. Numerous nurses have experienced mental health problems, such as anxiety. Design The STROBE guidelines for a cross‐sectional questionnaire were implemented. Methods An online survey of 643 frontline nurses working with COVID‐19 patients was conducted from March 3 to 10, 2020. Sociodemographic data were collected, and the Generalized Anxiety Disorder Scale, the Chinese Perceived Stress Scale, and the Athens Insomnia Scale were administered. Results One‐third (33.4%) of participants reported anxiety, which was associated with perceived stress and insomnia among Chinese frontline nurses in Wuhan during the COVID‐19 pandemic. Significant associations were found between anxiety, perceived stress, insomnia, working four‐night shifts per week, experience working during more than two epidemics, and fear of COVID‐19. Conclusions This study found that a substantial proportion of frontline nurses caring for COVID‐19 patients experienced anxiety. We recommend that nurse managers focus on working conditions and cultivate safe and satisfactory work environments. Meanwhile, frontline nurses should foster awareness of mental health and rely on online resources for psychological training to alleviate anxiety. Relevance to clinical practice The findings of this study could facilitate better understanding of anxiety among frontline nurses; more importantly, health care authorities and nursing managers need to pay more attention to ensuring intervention training to reduce anxiety for frontline nurses worldwide.

Due to the high infectivity and long incubation period of new coronary pneumonia virus (Li et al. 2020; Rothe et al. 2020), COVID-19 has evolved into a global pandemic, and more cases and isolation measures appear in the news. Since China first reported COVID-19 in December 2019, as of May 11, 2020, a total of 234 countries and regions have reported 234,073 confirmed cases and 9840 deaths. Although various measures have been taken globally to combat new coronary pneumonia for more than 5 months, the number of confirmed cases and deaths worldwide is still increasing dramatically. COVID-19 poses a huge challenge to public health worldwide (Pan et al. 2020) and has caused serious and widespread negative effects on human beings (Lin 2020; Ahorsu et al. 2020). The uncertainty and low predictability of COVID-19 not only threaten people's physical health, but also affect people's mental health, especially emotional, stress, and sleep problems (Rothe et al. 2020) COVID-19 is mainly spread through droplets, aerosols, etc. Therefore, the closer you are to the diagnosed patient, the more likely people are to be infected. People are required to stop work, suspend school, stop production, and restrict travel, so as to reduce the chance of exposure to COVID-19 patients. However, this isolation will also have a negative impact on people's mental health. But relative to COVID-19's direct physical and mental harm, isolation is still a good choice. But what about nurses on the frontline? Nurses who test and treat patients with COVID-19 have a
