Engineering has been playing an important role in serving and advancing healthcare. The term "Healthcare Engineering" has been used by professional societies, universities, scientific authors, and the healthcare industry for decades. However, the definition of "Healthcare Engineering" remains ambiguous. The purpose of this position paper is to present a definition of Healthcare Engineering as an academic discipline, an area of research, a field of specialty, and a profession. Healthcare Engineering is defined in terms of what it is, who performs it, where it is performed, and how it is performed, including its purpose, scope, topics, synergy, education/training, contributions, and prospects.Keywords: Healthcare engineering, definition, purpose, scope, topics, synergy, jobs, education, training, contributions, future
PREAMBLEEngineering has been playing a crucial role in serving healthcare, bringing about revolutionary advances in healthcare. Contributions have been made by engineers from almost all engineering disciplines, such as Biomedical, Chemical, Civil, Computer, Electrical, Environmental, Industrial, Information, Materials, Mechanical, Software, and Systems Engineering, as well as healthcare professionals such as physicians, dentists, nurses, pharmacists, allied health professionals, and health scientists who are engaged in supporting, improving, and/or advancing any aspect of healthcare through engineering approaches. "Healthcare Engineering" is the most appropriate term to encompass such a multi-disciplinary specialty, considering that advancing healthcare is the common goal for all such efforts made through engineering approaches. However, so far, a clear, rigorous definition of "Healthcare Engineering" has never been documented.Established over 50 years ago, the American Society of Healthcare Engineering (ASHE) [1] was one of the first to publicize the term "Healthcare Engineering". ASHE, as well as its many local affiliate societies (e.g., [2]), has been mainly dedicated to the health care physical environment, which represents only one sector of what engineers do in healthcare. David and Goodman [3] first used the term "healthcare engineers" in the scientific literature in 1989, where the critical role of the engineer in the healthcare delivery system was discussed. A number of academic programs have adopted the term "Healthcare Engineering" in their names (e.g., [4][5][6][7][8][9][10][11][12][13]). However, the description/definition of "Healthcare Engineering" by these programs varies, as each institution has designed its program based on its own distinctive interest, strength, focus, and emphasis, and hence created a different description/definition accordingly. Each of these versions of description/definition excellently portrays a certain facet of Healthcare Engineering, though none reflects all dimensions of the discipline. Further, the Journal of Healthcare Engineering [14], launched in 2010, focuses on engineering involved in all aspects of healthcare delivery processes and systems....
