It is generally accepted that nurses have insufficient knowledge about disaster preparedness due to a lack of acceptance of core competencies and the absence of disaster preparedness in nursing curricula. This study explored nurses' knowledge and sources of knowledge, and skills as they relate to disaster management in Saudi Arabia, where more than 4660 people have died, 32,000 people have been affected, and US$4.65 billion in damage has been caused by disaster since 1980.A quantitative, non-experimental, descriptive research design.Nurses in Saudi Arabia have moderate knowledge concerning disaster preparedness. However, nurses in military hospitals possess more knowledge than those who work in government hospitals. The majority of nurses gained their knowledge and skills from disaster drills.Nurses need more education in all areas of disaster management, most importantly in their roles during response to disasters. Nurses perceive themselves as not well-prepared but they are willing to improve their skills in disaster preparedness if educational opportunities are provided.
