Sacred Heart attacks dangerous bacteria in water system

Workers performed a chlorine flush of Providence Sacred Heart Medical Center’s water system Tuesday in hopes of killing clusters of bacteria that can cause Legionnaire’s disease.

Some patients have gone days without showers and baths and the hospital has served and sold bottled water to staff, patients and visitors after three Sacred Heart patients tested positive for Legionella bacteria this year.

Hospital officials said the water is being treated with chlorine at a level that should kill the bacteria but is low enough that it is safe to drink – 2 parts per million. Chlorinated swimming pools routinely have chlorine measurements between 1 and 3 parts per million.

Two of the three cases this year occurred in January. The patients had been cared for in the same room, though on different days. The third occurrence of the bacteria was in March.

All of the patients were elderly and were hospitalized with multiple illnesses. One of the January patients died, although the cause of death was not listed as pneumonia caused by the Legionella bacteria, said Sacred Heart’s chief medical director, Dr. Jeff Collins.

A positive test result from the federal Centers for Disease Control last month prompted the hospital to clean its water system – a major undertaking for the region’s largest hospital.
