The medical world is gradually realizing that the quality of the environment in hospitals may play an important role in helping patients to get better.

As part of nationwide effort in Britain to bring art out of the museum and into public places, some of the country’s best artists have been called in to change older hospitals and to soften the hard edges of modern buildings.

Of the 2,500 national health service hospitals in Britain, almost 100 now have very valuable collections of present art in passages (走廊), waiting areas and treatment rooms.

These recent movements first started by one artist, Peter Senior, who set up his studio at a Manchester hospital in northeastern England during the early 1970s. He felt the artist had lost his place in modern society, and that art should be enjoyed by a wider audience. A common hospital waiting room might have as many as 5,000 visitors each week. What a better place to hold regular exhibition of art! Senior held the first exhibition of his own paintings in the outpatients waiting area of the Manchester Royal Hospital in 1975. Believed to be Britain’s first hospital artist, Senior was so much in demand that a team of six young art school graduates soon joined him.

The effect is surprising. Now in the passages and waiting rooms, the visitor experiences a full view of fresh colors, playful images and restful courtyards.

The quality of the environment may reduce the need for expensive drugs when a patient is recovering from illness. A study has shown that patients who had a view onto garden needed half the number of strong painkillers compared with patients who had no view at all or only a brick wall to look at.
