The doctors and nurses wore the same suits, hats and masks, and it was difficult to tell who was who when doing an operation.To solve the problem, Rob Hackett, an anesthesiologist(麻醉师) in Sydney, Australia, had an idea to write his name on his hat. At the beginning, his workmates didn't take it seriously, even someone laughed at him, “Don’t you remember your name?”

Dr. Rob showed his thoughts on the website Bored Panda, “As we all know, doctors are a stressful job, and when facing with life and death danger, we have to race against time to try to save patients' lives. We need to create a culture that allows us to rebuild health care. We need to develop a system that reduces mistakes and errors.”

A year later, Rob had the last laugh. Surgical(外科手术)caps with names have been accepted around the world because of the following advantages:

※ This simple method can reduce human mistakes in medical care. Doctors found that doing this can find proper doctors and nurses in time, which greatly saves the time of communication.

※ The idea is to make patients feel human. The patient lies on sickbed, knowing who is doing the operation. This is also a kind of comfort which lets the patient feel less nervous.

※ In addition, writing names on the surgical hat is a new way to promote(促进) the recycled use of hats, with environmental benefits.
