BROCKTON — Bad advice from a South Shore Hospital nurse contributed to the death of a 3-month-old Duxbury girl seven years ago, a Plymouth Superior Court jury concluded this week.

After two days of deliberation, the 11-member jury decided that South Shore Hospital nurse Laura Perkins was negligent in her care of Natalie Core. The jury awarded the child's family $3.5 million.

Perkins was one of three defendants in the civil case. The other defendants, Dr. Zuzanna Kubicka and nurse practitioner Gretchen Hamn, were found not responsible.

Natalie Core was born prematurely in August 2012 and spent almost all of her life in the neonatal intensive care unit at South Shore Hospital. On Dec. 3, she was sent home from the hospital, according a lawsuit filed in Plymouth Superior Court.

The next day, after noticing that her daughter wasn't acting normally, Natalie's mother, Teresa Core, called the hospital twice. During one of the phone calls, Perkins assured Core that her daughter was fine and told her to keep her pediatric appointment scheduled for the next day, documents show. That advice, the jury decided, was a "substantial contributing factor" in Natalie's death.

"Nurse Perkins did not consult with anyone, including Dr. Kubicka, during or after the time that Mrs. Core spoke with her," court documents say. "Instead, nurse Perkins told Mrs. Core that there was no reason to be alarmed, and that Natalie was just adjusting."

Several hours after the phone call with Perkins, Natalie was found not breathing in her crib and taken to Jordan Hospital, now Beth Israel Deaconess Hospital-Plymouth. Natalie was pronounced dead at 11:15 p.m., 33 hours after being discharged from South Shore Hospital.

She died of bacterial meningitis with probable sepsis, according to an expert witness statement filed by Lubin & Meyer, the law firm that represented the Core family.

"To a reasonable degree of medical certainty, Natalie’s premature and preventable death was the direct result of the substandard care and treatment rendered to her," the statement said.

Robert Higgins, a lawyer with Lubin & Meyer, said Perkins is still employed at South Shore Hospital.

In a prepared statement issued Friday, hospital officials said, "We extend our deepest condolences to those who were affected by the child’s death; events like this are devastating for all involved. We sympathize with the family after such a great loss, while we respectfully disagree with the outcome of the case. We stand by the care given by our nurse."
