Health technology assessment applied to emergency preparedness: a new perspective.

Emergency preparedness is a continuous quality improvement process through which roles and responsibilities are defined to effectively anticipate, respond to, and recover from the impact of emergencies. This process results in documented plans that provide a backbone structure for developing the core capacities to address health threats. Nevertheless, several barriers can impair an effective preparedness planning, as it needs a 360° perspective to address each component according to the best evidence and practice. Preparedness planning shares common principles with health technology assessment (HTA) as both encompass a multidisciplinary and multistakeholder approach, follow an iterative cycle, adopt a 360° perspective on the impact of intervention measures, and conclude with decision-making support. Our "Perspective" illustrates how each HTA domain can address different component(s) of a preparedness plan that can indeed be seen as a container of multiple HTAs, which can then be used to populate the entire plan itself. This approach can allow one to overcome preparedness barriers, providing an independent, systematic, and robust tool to address the components and ensuring a comprehensive evaluation of their value in the mitigation of the impact of emergencies.
