Has it come to this？Robots standing in for doctors at the hospital patients’ bedside?
Not exactly, but some doctors have found a way to use a robot to check on patients while they’re miles away from the hospital.
One is at Baltimore’s Sinai Hospital.Equipped with cameras，a screen and microphone，the robot is guided into the rooms of Dr Alex Gandsas’ patients where he speaks to them as if he was right there.
“The system allows you to be anywhere in the hospital from anywhere in the world，” said the surgeon, who specializes in weightloss operation.
Besides his normal morning and afternoon personal visits, Gandsas uses the $150,000 robot to visit patients at night or when problems arise.The robot can circle the bed and adjust the position of its two cameras, giving the perception from the patient’s standpoint that the doctor is there.“They love it.They’d rather see me through the robot，” he said of his patients’ reaction to the machine.Nurse Florence Ford, who has worked with the robot since it was introduced about 18 months ago, said patients have reacted well, particularly because “seeing the doctor’s face gives them confidence”．
Gandsas presented the idea to hospital leaders as a method to more closely observe patients following weightloss operation.Since its introduction, Dr Alex found that nearly one third of his 376 patients went out of hospital earlier than first expected.
Michael Chan, president of InTouch Technologies, said his company’s device allows doctors to “be in more than one place at the same time”．
Speaking with Gandsas through one of the robots at company headquarters, Chan said the company designs applications for the devices in remote areas and for dealing with shortages of health care workers.“They will soon be big, ”said Chan when asked about their future.
