Baystate Medial Center is notifying 575 patients that state health officials found problems in its inpatient dialysis unit.

The Springfield hospital says there was “nearly zero” risk to patients, but the Massachusetts Department of Public Health says a “serious lapse” occurred.

Among the problems — according to Baystate’s vice president of medical affairs, Doug Salvador — nurses at times failed to change gloves between touching a patient and the dialysis machine.

“Because of usually a desire to multitask and take care of what the patient is asking for, and whatever needs to be done in the environment, you might not re-glove between every recommended instance that you should,” Salvador says.

But he says the machines were sanitized in-between each patient.

Baystate says there’s no evidence any disease was transmitted and for most patients it’s not recommending testing, but will pay for it if a patient wants it.

That testing, according to the state Department of Public Health, would cover Hepatitis B and C, and HIV. The state says it required Baystate to notify patients receiving dialysis at the hospital between January 1, 2015, and February 10 of this year.

“DPH’s investigation into this serious lapse by Baystate Medical Center remains open,” DPH spokesperson Scott Zoback said in a statement, adding that the risk to patients is “considered low.”

“DPH will continue monitoring the situation, and working to ensure patient safety standards are upheld at Baystate Medical,” Zoback said.

This disclosure follows the company’s announcement in January that nearly 300 patients at Baystate Noble Hospital in Westfield faced a “small risk” of exposure to blood-borne pathogens. That’s because — a couple years before Baystate bought Noble — the hospital incorrectly disinfected part of a scope used in colonoscopies.
