Training changes the math: the evidence on BMET education in LMICs

If you could make one investment to raise the share of working medical equipment in a low-resource health system, what would it be? More devices? More parts? The research keeps pointing somewhere less obvious: more trained people.

Engineering World Health and partners developed biomedical equipment technician (BMET) training programs deployed in Rwanda, Honduras, and Cambodia. Published evaluations of those programs reported substantial decreases in non-functional equipment — on the order of 30–43% — after training and placement, with trained technicians dramatically more productive than untrained peers.

A separate study from rural Nepal, published in BMC Health Services Research, examined what happened when government hospitals simply deployed a trained BMET where previously there was none: equipment functionality improved markedly, because faults that once waited for an outside contractor — or were never reported at all — were caught and fixed in-house.

None of this should be surprising. High-income health systems learned the same lesson decades ago when they professionalized healthcare technology management. What's encouraging is seeing the evidence accumulate that the lesson transfers: the technician is the technology's other half, everywhere on Earth.

It also reframes what generous people in our field can offer. A donated device helps one hospital. A mentored technician helps every device that ever passes through their hands — for an entire career.

That's why education is a pillar of our network and not a side program. Coursework, hands-on practice, and a mentor who answers the phone: it's the highest-leverage equipment intervention we know of, and the evidence agrees.
