Robots improve safety, efficiency at Thai hospital

A Thai hospital famous for medical tourism and celebrated for its use of new technologies is turning to robotics to become more efficient and improve patient safety.

The idea isn't to create a nursing staff of Honda Asimo humanoid robots; rather, it's to automate some of the hospital jobs performed by humans where mistakes can be fatal.

"Robotics helps immensely in eliminating errors," said Chang Foo, chief technology officer at Bumrungrad International Hospital in Bangkok. "We have a large emphasis on technology and we evaluate where errors occur, and it's mostly human error," he said.

It's a universal problem in health care. A landmark study by the Institute of Medicine called "To Err Is Human" found that as many as 98,000 people died each year in the U.S. due to mistakes such as giving patients the wrong medicine.

Perhaps scarier than the fatal errors is that the study is a decade old, and that a follow-up published four years ago in the Journal of the American Medical Association found that progress on the issues raised had been "frustratingly slow."

Bumrungrad has already seen how robots can benefit hospitals. Staff are so enthusiastic about robots from a company called Swisslog Holdings that you might mistake them for a Swisslog sales team.

The hospital uses several Swisslog systems, including at least three robots. These are not androids like C3PO or R2D2, but more like box-shaped automated machines with conveyor belts, storage racks and robotic arms that move around pills and laboratory test samples such as blood and urine.

Two of the robots, PillPicker and BoxPicker, have boosted safety significantly at the hospital, Foo says.

PillPicker sorts pills and dosages into individual plastic bags and affixes them with barcodes that say what's inside each one before placing them in a storage area. When a prescription arrives to be filled, BoxPicker sifts through the rows of medicines to pick out the ones it needs with its robotic arm, then binds them together in a package with a new barcode tag stating which patient the medicine is for.
