A well-known clinical engineering (CE) pioneer, Ode Keil, recently wrote an essay in the Journal of Clinical Engineering wondering whether CE is on life support.1 In the 1960s, he wrote, the thinking was that a “graduate-degreed clinical engineer” was needed in healthcare organizations to help clinicians and administrators manage the rapid introduction of technologies and to address issues including equipment selection, user education and training, and software integration. Today, Keil believes CE is in danger of extinction because of the combination of three factors: advances in information technology (IT), cost control (“money”), and poor communication skills.

Hope for the Future

 This article marks the debut of “CE Perspectives,” a bimonthly column dedicated to the discussion of current issues and concerns for clinical engineering professionals. This column replaces “CCE Prep” by Arif Subhan, who will serve as contributing editor for CE Perspectives. 

While I agree with some of the concerns he expressed, I am definitely not as pessimistic about our future.  First, I would like to make a distinction between a CE professional and a “graduate-degreed clinical engineer.” Even though Keil did not say a 4-year engineering degree is a minimum requirement, I think it is worthwhile to clarify my viewpoint so the readers can understand the rest of this article. I believe everyone who manages and maintains medical equipment deserves to be called a CE professional, regardless of the degree he or she earned. (Would anyone like to argue with me that the recently deceased Joel Nobel, founder of ECRI Institute, should not be considered a CE professional and pioneer simply because he was a medical doctor and never earned an engineering degree?)

Within the various categories of CE professionals, those with earned degrees (and certifications) deserve respect for their investment in education and the expertise they have acquired. However, they should not be considered the sole CE professionals in the field. Biomedical technicians, imaging specialists, and equipment distribution staff are all needed, and deserve to be considered CE professionals as well.

It is true that IT and, more appropriately, the rapid evolution of electronics, material sciences, and software, have resulted in profound changes to medical equipment and, thus, the CE profession. However, the enhanced reliability of solid-state-based equipment and the fact that roughly 25% of CE departments are now under the supervision of IT do not mean that CE professionals are no longer needed for anything beyond the basic tasks of repairs and asset management. The challenges of equipment selection, user training, risk and safety management, software integration, human-factors engineering, and similar issues have actually increased since the 1960s. Just as medical equipment is nothing but a tool for clinicians to deliver health services, IT has likewise become another pervasive—and often invisible—tool for most professionals to perform their jobs.

Financial Realities

Cost control has undeniably affected the way many healthcare executives perceive CE. The illusion of perfect safety at any cost has caught up with the reality that Americans spend more per capita than the citizens of any other industrialized nation and yet don’t have the best outcomes.2 CE cannot escape from this reality and must find ways to be more efficient by eliminating waste (such as performing unjustified scheduled safety and performance inspections, blindly following manufacturers’ recommendations, and requiring only “genuine” parts). Good examples of the efficiency that can be achieved by sharing expensive resources (including CE professionals with advanced degrees and specialized skills) include the outsourcing of CE services, the formation of large health systems, and collecting and analyzing large amounts of maintenance data.

Poor communication skills is indeed one of the serious handicaps that many engineering, not just CE, professionals have. This should not be surprising, as it is widely known that the high-school nerds attend science and engineering schools, while the gregarious ones go to business, health sciences, or social studies. However, this kind of skill can be learned (as can another important one: finance). Much harder is the reverse, as engineering expertise requires years of mathematics and physics foundation, as well as systematic, critical thinking. (By the way, I think the reason Keil wrote that, “The least important part of being a clinical engineer is the technical knowledge and understanding of technology,” was only to emphasize his point that CE professionals “are irrelevant if no one is listening.”)

Concerns for the Future

On the other hand, I do share some of Keil’s concerns for the future of CE for other reasons. First and foremost, CE professionals are notorious for not willing to learn3 from and collaborate with one another, even when their livelihoods are threatened and their professional expertise is questioned. This was evident in the struggle with the edicts issued by the Centers for Medicare & Medicaid Services in the last 3 years. Our lack of cohesiveness and political savvy allowed companies to impose their wishes through political maneuvers.4

Another symptom of weak professionalism is the fact that licensure has not become a reality after more than half century of existence as a professional field.5,6 In the meantime, several other healthcare professions that started in the same era (such as respiratory therapy and physical therapy) have attained it. The lack of licensure also translates into the lack of CE undergraduate programs and the very small number of graduate programs. Without a clear professional career path, few college students are willing to venture into the field, even though new biomedical engineering graduates have had a tough time finding jobs in the industry for the last 5 years, while many healthcare and service organizations have had many unfilled vacancies.

I do agree with Keil that the future depends on us. I hope we will not become our own worst enemies. If we are not willing to fight together for our place under the sun, we should stop complaining that we are stuck in the basement next to the morgue!
