This review was undertaken to identify the perceived barriers and facilitators of nurses' and physicians' willingness to work during a respiratory disease outbreak. This mixed-methods systematic review involved the extraction of data from the electronic databases PubMed, Web of Science, CINAHL, and PsycINFO and from a manual search of articles published between 2003 and April 2021. The quality of the included studies was assessed using a mixed-method appraisal tool. A total of 29 studies were eligible for inclusion: 21 quantitative and 8 qualitative. Using the Integrated Behavioral Model, perceived barriers and facilitators were identified under seven categories: demographics, attitude, perceived norm, personal agency, knowledge and skills to perform the behavior, environmental constraints, and habit. The results of this study broaden the understanding of various factors that affect nurses' and physicians' willingness to work during a respiratory disease outbreak. These findings will facilitate the modification of current pandemic workplace staffing strategies and practices and will inform preparedness planning for similar situations in the future.
