Their inherent focus on "practical" implementation of technology has tended to keep them oriented more towards "incremental"-level redesigns and reconfigurations, as opposed to "revolutionary" R&D or cutting-edge ideas that would be many years from clinical adoptability; however, there is an effort to expand this time-horizon over which clinical engineers can influence the trajectory of biomedical innovation. In their various roles, they form a sort of "bridge" between product originators and end-users, by combining the perspectives of being both close to the point-of-use, while also trained in product and process design. Clinical engineering departments at large hospitals will sometimes hire not just biomedical engineers, but also IT, industrial/systems engineers to help address operations research, human factors, cost analyses, safety, etc.
