Sunlight reduces need for pain medication

By Marilyn Elias, USA TODAY

 

Sunlight may be a key prescription for easing surgical pain and

saving millions of dollars in hospital pharmacy costs, according to

a study out Wednesday.

 

Surgery patients in rooms with lots of natural light took less pain

medication, and their drug costs ran 21% less than for equally ill

patients assigned to darker rooms, a scientist will report.

Those in the brighter rooms also had lower stress levels and said

they felt less pain the day after surgery and at discharge, says

Bruce Rabin, a physician and immunologist at the University of

Pittsburgh. He'll present the findings at the American Psychosomatic

Society meeting in Orlando.

 

It's thought to be the first evidence that sunlight can affect the

perception of pain. Findings will generate major attention at

hospitals, predicts Dale Woodin, a health care engineering expert

with the American Hospital Association in Chicago. " Whenever you can

tie the environment to clinical outcomes and costs like this, it's

huge, " Woodin says.Light meters showed that darker rooms at

Montefiore University Hospital in Pittsburgh had 46% less natural

light than those on the sunny side, says Rabin and co-author Jeffrey

Walch. They randomly housed 89 spinal fusion surgery patients on one

side or the other. Although the hospital light came from the sun,

some bulbs on the market are advertised as duplicating natural

sunlight, Rabin says.

 

Hospital pharmacies spent more than $21 billion in 2002, says

pharmacist Lee Vermeulen of the University of Wisconsin, whose team

does yearly reports from numbers collected by IMS Health.

" It's very impressive to get savings in the 20% range, " Vermeulen

says. Pain medications are not among the most expensive drugs used

in hospitals, he says. But heavy use of pain relief drugs often

creates gastrointestinal problems and delays walking, which can

cause doctors to prescribe blood thinners and other expensive drugs.

Rabin and Walch haven't looked at overall drug usage yet.There's

strong evidence that people feel less pain if they're in a better

mood and under less stress, says Russell Portenoy, chairman of the

department of pain medicine and palliative care at Beth Israel

Medical Center in New York. Bright light has been shown to improve

mood, " so mood may be what's leading them to use less pain

medication, " he says. Bright light triggers the release of

" feel good " brain chemicals such as serotonin, some research has

found.Also, nurses and doctors may be cheered by the brightly lit

rooms and treat patients differently than those in dim rooms. Such

differing treatment could reduce drug use, too, Portenoy adds.

 

Hospital planners are aiming for more natural light, says Woodin,

but it's often easier to capture sunlight with a new building than a

remodeled older one. " Even the older ones are trying to move toward

more light. We really need to get away from those long, dark

corridors of old-time hospitals. "
