According to KMOV.com, the incident happened Monday at the U.S. Renal Care at 13190 South Outer 40 Road.
The seven patients were hospitalized, three in critical condition, after receving the wrong solution during dialysis, KMOV reported Tuesday. A Renal Care spokesperson reportedly told KMOV that all seven were taken to area hospitals, including Missouri Baptist Medical Center in Town and Country. One person has since been discharged from the hospital.
The center reportedly became aware of the mix-up when the patients receiving dialysis said they began feeling uncomfortable, according to KMOV.
According to a U.S. Renal Care news release, the company acquired the Town and Country dialysis center in August. It cares for patients suffering from chronic kidney failure known as end stage renal disease. The facility was formerly known as Premiere Dialysis, KMOV reports.
According to U.S. Renal Care, the company serves 6,400 end stage renal disease patients and operates in 13 states.
