Eighteen people were being treated at the time when three reported feeling ill.
BOARDMAN -- Three patients of Physicians Dialysis Center, Boardman-Canfield Road, were taken to the hospital this week after showing signs of infection.
Terry Proveaux, a spokeswoman for the corporate office in Nashville, said the three patients told personnel they didn't feel well when they arrived Tuesday.
Personnel monitored their conditions during treatment and sent them to the hospital when the symptoms, including fever, continued. Proveaux classified the symptoms as indicative of some type of infection.
Blood and water samples were taken to try to determine the source of the problem. Preliminary tests on the water haven't shown any problems, she said. Blood results are expected today.
Of the 18 people undergoing dialysis at the time, the three sent to the hospital were the only ones who exhibited symptoms, Proveaux said.
Patients who received treatment using the same equipment later that day and on Wednesday didn't report problems, Proveaux said.
"Our suspicion is that it's unique to these patients," Proveaux said, adding that they don't believe either the water or the equipment at the center caused the problem.
The center remains open.
Patients undergo dialysis for three to four hours, three days per week.
In August 2000, 20 patients became ill and one died after being treated at a Physicians Dialysis Center on Belmont Avenue, Youngstown. That center was closed for more than a month.
Testing at that time showed elevated bacterial levels in the water supply being used in the dialysis treatments.
