Disaster response demands a large workforce covering diverse professional sectors. Throughout this article, we illustrate the results of a systematic review of peer-reviewed studies to identify existing competency sets for disaster management and humanitarian assistance that would serve as guidance for the development of a common disaster curriculum. A systematic review of English-language articles was performed on PubMed, Google Scholar, Scopus, ERIC, and Cochrane Library. Studies were included if reporting competency domains, abilities, knowledge, skills, or attitudes for professionals involved disaster relief or humanitarian assistance. Exclusion criteria included abstracts, citations, case studies, and studies not dealing with disasters or humanitarian assistance. Thirty-eight papers were analyzed. Target audience was defined in all articles. Five references (13%) reported cross-sectorial competencies. Most of the articles (81.6%) were specific to health care. Eighteen (47%) papers included competencies for at least 2 different disciplines and 18 (47%) for different professional groups. Nursing was the most widely represented cadre. Eighteen papers (47%) defined competency domains and 36 (94%) reported list of competencies. Nineteen articles (50%) adopted consensus-building to define competencies, and 12 (31%) included competencies adapted to different professional responsibility levels. This systematic review revealed that the largest number of papers were mainly focused on the health care sector and presented a lack of agreement on the terminology used for competency-based definition.

Aid workers are often required to operate within disrupted political systems with no pre-existing disaster plans 2 and to perform tasks that fall outside their area of expertise, especially the management of refugees and internally displaced populations, communicable diseases, and the lack of critical resources.3 Lessons learned from relevant disasters-such as Haiti (2010), the Asian tsunami (2004), the Haiyan Typhoon (2013), and the current Ebola virus disease tragedies in West Africacall for attention to the limited capability of foreign medical teams to meet challenges posed by complex emergencies. [4][5][6][7][8][9] These concerns have prompted the international community to devise means for the development of both competence and professionalism within the humanitarian assistance sector. 4,6 Disaster response demands a large workforce with diverse professional disciplines, subspecialty categories, and levels of professional experience and cultural expertise. Regardless of their professional background, education for personnel operating i...
