GREENVILLE, S.C. — Shriners hospitals, which have provided free care since before the Great Depression, are considering closing a quarter of their facilities as donations stagnate, costs increase and the charity's endowment shrivels.

The group's director says it's the only viable option.

Officials at the Florida-based organization say it is siphoning $1 million a day from its endowment to balance the budget for 22 hospitals in the U.S., Canada and Mexico. Meanwhile, they say, that fund has fallen to $5 billion from $8 billion in less than a year because of the sputtering stock market and a charitable giving slump that has hurt philanthropies nationwide. The fund has been declining since 2001. The group will vote this summer on the closures.

"Unless we do something, the clock is ticking and within five to seven years we'll probably be out of the hospital business and not have any hospitals," Ralph Semb, chief executive officer of Shriners Hospitals for Children, told The Associated Press.

In cities where hospitals may close, supporters and hospital staff are scheduling fundraisers and posting online messages of support on social networking Web sites.

In Greenville, S.C., Bridget Myers and her daughter are turning to churches and friends, collecting money in a bucket tagged with pictures of X-rays and Shriners patients.

"I've collected 92 dollars in two days," said Brooklynn Myers, 14, who received scoliosis treatment at the Shriners' Greenville hospital. "Me and my mom feel like it's heartbreaking we'd have to drive all the way to Lexington (Ky.) and we've made special bonds here."

Widely known today for burn and orthopedic care for children, the Shriners Hospitals system opened in 1922 with a facility in Shreveport, La., that specialized in treating polio. By the 1960s, the group had hospitals nationwide and expanded its care to include spinal cord injury rehabilitation, cleft lip and palate care and medical research.

More than 1 million children have been treated at the hospitals, which were created by the fraternal organization of the same name whose members are known for wearing red fezzes and driving miniature cars in parades. The care is free to all.

In 2007, the fraternal group was hit with accusations it used money intended for the hospitals to throw parties — but only a fraction of the hospitals' funds are raised by the group. Most of the money to operate the hospitals has come from interest from the endowment, Semb said.

Semb said this year's operating budget for the hospital system is $856 million. The budget has risen by $100 million each of the past two years while donation levels remained static, he said.
