Description:
Welcome to Signal Path. I'm Nadia Reyes, and today we're tracing a profession that most patients never see but every patient depends on.My guest is Dr. Arun Patel, a clinical engineering educator who has spent two decades training hospital technology teams.
Thanks, Nadia. Good to be here.
Let's start with the basics. What actually is a clinical engineer?
The clearest definition comes from the source itself: clinical engineers are biomedical engineers who serve at the point of care.And the global community, meaning the Global Clinical Engineering Alliance plus the IFMBE Clinical Engineering Division, puts the worldwide population at roughly one million CE professionals.
How big is that community when you look at the map?
As of 2023, over eleven hundred CE collaborators represented more than 210 countries: ministers of health, physicians, engineers, medical physicists, technologists, professors, and WHO representatives. About a third are women, and half those countries are classified by the World Bank as low- and middle-income.The fifth International Clinical Engineering and Health Technology Management Congress drew over 200 presenters from 110 countries in November 2023, followed immediately by the World Health Innovation Forum.
This profession didn't appear overnight, though.
The source traces it to Otto Schmitt, whose 1934 Schmitt Trigger, built to study squid nerve, became the basis of today's analog-to-digital converters, and to Cesar Caceres, who described computer diagnosis in 1961 and the computer electrocardiogram in 1962.By the 1970s, a 481-page volume edited by Caceres, The Practice of Clinical Engineering, defined the field as distinct from biomedical and bio-engineering, and the US Journal of Clinical Engineering emerged.There's a line in the presentation I keep coming back to: most clinical engineers are biomedical engineers, but few biomedical engineers are clinical engineers.
So what separates the two?
Breadth. One presenter lists twenty-five disciplines in his own credentials: hospital operations, patient safety and ethics, cybersecurity, digital health, systems engineering, sterilization, standards, supply chain, governance. And he insists he is not unique. A 2022 Chinese survey found very similar skill sets.
That blend of clinical fluency and engineering depth is exactly why this role is so hard to hire for.
The evidence backs that up. A 2022 Body of Knowledge and Body of Practice survey drew 870 responders, and China alone contributed 180. By WHO region, Africa accounted for 237 responses, the Western Pacific 214, and the Americas 198.One tally line in that table lists 128 responses tied to LMIC-designated countries, though the summary breakdown is dense enough that I'd treat that figure carefully.Then came COVID-19. The alliance and the IFMBE division, working with WHO, ran more than 90 global webinars between 2020 and 2023, almost entirely volunteer-produced. Representation grew from 70 countries at the 2019 congress to over 210 by the end of 2022.WHO's 2007 resolution WHA60.29 had already called for effective planning, assessment, acquisition and management of health technologies, especially medical devices. The pandemic made it urgent: 2020's question was where are the ventilators, and 2021's was where are the oxygen sources.WHO's Medical Device Unit, led by Adriana Velazquez Berumen, saw its scope expand from devices to PPE, oxygen delivery tools, and digital health tools.
And individual engineers stepped up as well.
The presentation collects those stories. In Paraguay, AI screening stratified COVID patient risk. In Pakistan, an LMIC-capable electronic medical record. In India, oxygen concentrators staged across 80 warehouses, leased at about five dollars a day. In the UK, digital pulse oximeters giving NHS-wide early warning of falling oxygen. In Kenya, a country-wide surveillance system. And in China, patient-centered digital health piloted since 2012.A second set covers AI for sepsis in Colombia, freeware asset management in Mexico that tracked emergency-use ventilators nationwide, cybersecurity training, telehealth access to specialists, a CE-IT certification effort, and remote monitoring reaching places with no care at all.The same section estimates workforce added value in bands: roughly 25 to 50 percent for low impact, 20 to 75 percent for medium, and above 75 percent for high.It also frames digital health as spanning robotics, artificial intelligence, big data and electronic records, cybersecurity, telehealth, remote patient monitoring, virtual ICUs, and autonomous or semi-autonomous medical devices.
That is a striking amount of ground, and it's being covered by people who also manage the equipment room.
Which raises the stakes. A 2022 report cited in the source notes that of 130 million US emergency department visits each year, nearly six percent are misdiagnosed and two percent involve an adverse event.The presenter's own conclusion is blunt: these are systemic problems, not just human or technology problems.Earlier, a survey run between 2017 and 2019 found 85 percent of responders would join an international CE organization, and 93 percent acknowledged the importance of creating one.The alliance's own pillars are a peer-reviewed, Scopus-indexed open-access journal published and translated in China, educational webinars and international congresses, and professional certifications. Global Clinical Engineering Day launches in China every October.Its call to action has three parts: educate the workforce for greater collaboration and resiliency, build national health technology policy, and form national and international alliances that share expertise.And the closing line is really the thesis: we must prepare competent clinical engineers and connect them to their intended roles in the future healthcare sector, not the present one.
A good place to leave it: a million-person profession, mostly invisible, quietly holding the technology layer of healthcare together.That's Signal Path for this episode. Thanks for listening.
