Despite the acknowledged promise of developing a public health systems research (PHSR) agenda for emergency preparedness, there has been no systematic review of the literature in this area. The purpose of this study was to conduct a systematic literature review in order to identify and characterize the PHSR literature produced in the U.S. in the past 11 years in the field of public health emergency preparedness. ⋯ Since 2001, the PHSR literature on PHEP issues has grown at about 33% per year. However, most studies lack a rigorous design, raising questions about the validity of the results.
