Abstract: Objective: To evaluate the effect of short-term training on the knowledge of COVID-19. Methods: Based on real-time updated knowledge of COVID-19, a six-stage roller-type training was conducted for 2099 nurses in a tertiary grade A general hospital in Beijing. After the training, the online-based coverage assessment and offline-assisted interpenetrating training quality evaluation was implemented, and a self-designed questionnaire was used to complete the evaluation of the training methods by all nurses. Results: There were no significant differences in the assessment results of the stages (P=0.482). In the training quality evaluation, the score of offline examination was 90.35±12.01, and the score of quality inspection was 90.47±12.84. In the evaluation of nurses training system, 98.9% of nurses liked this training method, and 99.3% of nurses thought the training content was updated in a timely manner and set reasonably, which was conducive to mastering the training content (99.4%), improving self-protection during the epidemic (99.5%), improving self-learning ability (99.4%) and enhancing the importance of COVID-19 (99.5%). Conclusion: During the outbreak of COVID-19, short-term training was a new method for online staff training for the nature of infectious diseases, and has achieved good results in practice. It can be non-aggregated and updated quickly during the outbreak, and effectively improve nurses' knowledge of COVID-19.
