We were excited to see a study by Cahan et al1 reporting on “human factors” curriculum for surgical clerkship students in the December 2010 issue of the Archives of Surgery. Human factors research is underutilized in health care and has tremendous potential benefit to improve health care systems and patient safety. However, the human factors curriculum reported in the article covers only a small fraction of the scientific discipline of human factors,2 as the accompanying critique shows.3 As Hu and Greenberg3 note, an accurate and comprehensive understanding of the term human factors is needed before a human factors curriculum in surgery can be designed.3 The purpose of this correspondence is to provide the basis for that understanding, written from the perspective of human factors professionals, so that readers of Archives can have a broader appreciation for the potential benefits of a partnership with human factors professionals. The science of human factors is concerned with the design of technology, processes, and work systems so that they are compatible with human cognitive and physical capabilities and limitations. Thus, although the curriculum described by Cahan et al1 addresses an important void in communication skills and training for surgical students, it is not fully representative of the science of human factors. Examples of human factors problems related to the surgical environment that are not covered by Cahan et al1 but that would be highly beneficial to surgical professionals would include:
