This series of events and hospital stays has given me a lot of time to observe the patient-staff interactions of a small slice of the healthcare system from the “System Safety” point of view. There are many excellent papers on many safety aspects of the healthcare industry, including Dev Raheja’s extensive writings about many of the system safety issues found with health care facilities. His many “System Safety in Healthcare” articles in the Journal of System Safety cover a wide range of topics, from the importance of system safety analyses for medical hardware to the “softer” human factors issues of providing healthcare. His articles are an excellent source of information, considerations and recommendations for improvements across the field of healthcare. In this article I am looking at the problems from a slightly different perspective, that of a “user” of the healthcare system.

Author Biography

Charles Hoes, Hoes Engineering

Charles “Charlie” Hoes began his consulting business in 1984, providing system safety engineering services to defense, aerospace, semiconductor and general industry. During that time he has become a P.E. in Safety in the State of California, a Certified Safety Profession (CSP) with a specialty System Safety Practices and earned a Master of Science degree in Safety from University of Southern California. In 1988 Charlie incorporated his business under the name of “Hoes Engineering, Inc.” He has many years of experience volunteering in support of the International System Safety Society, filling many positions including past President of the Sacramento Chapter, the Virtual Chapter, and the System Safety Society. He is a past technical editor of the System Society’s journal Hazard Prevention (re-named to be the Journal of System Safety), as well as authoring an ongoing feature article of the Journal of System Safety called “TBD” where he discusses current concerns with the system safety profession.

In his new role of being semi-retired, Charlie continues to actively work with the System Safety Society as well as participating in a few “for hire” and volunteer projects that are particularly interesting, or important, for a variety of reasons. He is enjoying the ability of being a bit more selective with regard to projects that he accepts.
