Two premature babies died at the Princess Royal Maternity Hospital after an outbreak of Staphylococcus aureus circulatory infection
An Incident Management Team was established to investigate three cases of Staphylococcus infections in a neonatal unit at Glasgow Hospital.
The infection was one of several causes of both deaths and NHS Greater Glasgow and Clyde said two children were very bad due to their early birth.
A third prematurely born child who was positive for Staphylococcus aureus needed to treat the bacterium and was in a stable condition.
Dr. Barbara Weinhardt, doctor of infection control, said: "Our thoughts are with affected families.
“The results today confirmed that three cases of Staphylococcus aureus are related and our research continues as they are.
“Staphylococcus aureus is a bacterium found on the skin and in the nasal tube that contains about one in four people, and only when it enters the body.
“When people are vulnerable to infections, they can cause serious infections.
"We have carried out a number of control measures within the unit, including deep, clean, insulating and barrier-feeding, safety briefing for all employees, and infection control advice for all visitors."
Dr Alan Mathers, Chief Medical Officer, Women's and Children's Service, added: “National guidelines require that investigations be initiated when two or more cases of the same type of bacteria are detected.
“In this case, it was launched on January 24 and the Incident Management Team meeting (IMT) was convened.
“IMT launched an investigation into possible links between the three cases and sent samples for testing.
“Although these results were expected, we talked to affected families with parents about the unit and staff to let them know about our investigation.
“The results that have come back today have confirmed the link between the three things.
"Our infection control team continues to work closely with clinical colleagues and local staff to manage the situation and take all the necessary steps to maintain patient safety."
Lisa Ritchie, Health Care Scotland Health Advisor, said: "Health protection Scotland supports NHS Greater Glasgow and Clyde to ensure that all precautionary and control measures are taken in accordance with national guidelines."
