Impact of COVID-19 on ICU nurses’ psychology and influencing factors under COVID-19’s normalization, prevention and control: A cross-sectional survey (preprint)

Background: The first-line ICU nurses still play an important role in the nursing of patients diagnosed by designated hospitals during the normalization prevention and control of COVID-19. Discussing the mental health status of the first-line ICU nurses will help to provide more accurate measures to improve the mental status of the first-line ICU nurses and improve the quality of nursing. Aims: To explore the impact and possible influencing factors of the novel coronavirus (COVID-19) on the psychology of ICU nurses under the normalization, prevention and control. Design: A cross-sectional survey. Method: We chose 40 ICU nurses working in designated hospitals for novel coronavirus pneumonia in October to December of 2021. A post-traumatic stress disorder survey scale and questionnaire were used to investigate the situation and stressors of first-line ICU nurses. Results: The average score on post-traumatic stress disorder of first-line ICU nurses was(21.68 + 6.76 ) points under the normalization of prevention and control of COVID-19. Two nurses scored 38 points and had significant clinical symptoms, making the incidence of post-traumatic stress disorder 5%. The main stressors included the discomfort of wearing protective equipment and the concern for relatives at home. Conclusions: This study shows COVID-19 has little effect on the mental health of front-line ICU nurses and exerts a lighter degree of pressure during the normalization of COVID-19. We can also further improve the psychological status of front-line ICU nurses by improving the quality of protective equipment, increasing ICU staff, obtaining the understanding and support of family members, hierarchical training, and the care and support of managers to further improve the quality of nursing.

Team Resilience under Shock: An Empirical Analysis of GitHub Repositories during Early COVID-19 Pandemic (preprint)

While many organizations have shifted to working remotely during the COVID-19 pandemic, how the remote workforce and the remote teams are influenced by and would respond to this and future shocks remain largely unknown. Software developers have relied on remote collaborations long before the pandemic, working in virtual teams (GitHub repositories). The dynamics of these repositories through the pandemic provide a unique opportunity to understand how remote teams react under shock. This work presents a systematic analysis. We measure the overall effect of the early pandemic on public GitHub repositories by comparing their sizes and productivity with the counterfactual outcomes forecasted as if there were no pandemic. We find that the productivity level and the number of active members of these teams vary significantly during different periods of the pandemic. We then conduct a finer-grained investigation and study the heterogeneous effects of the shock on individual teams. We find that the resilience of a team is highly correlated to certain properties of the team before the pandemic. Through a bootstrapped regression analysis, we reveal which types of teams are robust or fragile to the shock.
