Greg Burke, Vatican spokesman, confirmed in a written statement July 3 that "After hearing complaints about care at the hospital three years ago, the Holy See moved quickly and decisively to study them seriously. After collecting the criticism, a clinical team was commissioned to look at the accusations and visit the hospital. The team found an exceptional level of care at the hospital, and that the accusations were unfounded."

"The sole critical note concerned inadequate space in intensive care units, something hospital officials are aware of and working to improve," Burke wrote.

He said the church "welcomes any efforts to help improve that care in its hospitals, including reports of practices that might be below standard. No hospital is perfect, but it is false and unjust to suggest that there are serious threats to the health of children at Bambino Gesu."

Cardinal Parolin told AP that some of the problems reported by former and current hospital staff in 2014 had been "truly unfounded," but that "there was an attempt, and there is currently an attempt and serious effort to resolve" those problems that had been confirmed.

Meanwhile, the hospital's president, Mariella Enoc, told the AP July 4 that the climate at the hospital had become "more serene" since she was appointed by Cardinal Parolin in early 2015. She said she was calling for more open communication and urging people to come forward with any problems in order to talk "and not keep it inside and then have it explode."

Enoc was appointed after the resignation of Giuseppe Profiti, who had been president of the hospital since 2008. He left less than a year into a renewed term right before the January 2015 onsite Vatican inspection of the hospital, amid rumors that a significant amount of money from the foundation supporting the children's hospital was used to help finance the remodeling of the apartment of former Secretary of State Cardinal Tarcisio Bertone.

Profiti and Massimo Spina, former treasurer of the hospital, were then subjected to a Vatican investigation in connection to the financing case.

In November 2015, Cardinal Parolin put in a new board of advisers at the Bambino Gesu Foundation with a new set of statutes aimed improving the fundraising body's transparency.

In December 2015, Pope Francis established a special pontifical commission to study entities operating in the name of the Catholic Church in the field of health care. The body, under the guidance of Cardinal Parolin, who also named Enoc as one of its members, aims to study and propose ways to increase efficiencies, improve governance and collaboration, and protect the religious mission and charisms of the clinics, hospitals or institutes.

When Pope Francis met with staff and patients of the Bambino Gesu hospital Dec. 15, 2016, he emphasized how all those working in the field of health care must help their patients and be on guard against falling down the slippery slope of corruption that begins with special favors, tips and bribes.

"The worst cancer in a hospital like this is corruption," he said. "In this world where there is so much business involved in health care, so many people are tricked by the sickness industry, Bambino Gesu hospital must learn to say no. Yes, we all are sinners. Corrupt, never."
