Hybrid operating rooms are safer for patients because they give surgeons the ability to do more invasive operations in the same operating room, such as with cardiovascular procedures, Lynch said.

At the same time, they enable less invasive surgeries by providing room for surgical robots and a rotating imaging system to provide real-time views during surgery.

Young surgeons around the country train with that type of advanced equipment, Lynch said.

"This will allow us to be competitive for the best and brightest," he said.

The ability to perform high-resolution imaging during an operation or procedure is of critical importance in minimally invasive vascular surgery, but also has applications in complex orthopedic, neurosurgical, thoracic and trauma cases, said Dr. Nicholas Gilpin, chief medical officer, in an emailed statement.

"Most hybrid ORs in existence are used primarily for vascular surgery, but there is considerable opportunity for other types of surgery as well," Gilpin said.

Electrical system upgrades are already underway at the Grosse Pointe hospital to prepare for the work that will begin this month, Lynch said.

The work will take place in phases, with one operating room taken offline at a time and a goal of completing the renovations by early summer 2022, Lynch said.

The landlocked hospital will enlarge its operating rooms by absorbing storage rooms and similar spaces within its current footprint, he said.

"As technology has moved forward … more and more equipment is needed in each one of our rooms," Lynch said.

"The renovation allows us to right-size all of our operating rooms."

The larger operating rooms will also permit more medical students, residents and fellows to observe and take part in procedures, Beaumont said.

Southfield-based Harley Ellis Devereaux Corp. is the architect on the project, and Sterling Heights-based Roncelli Inc. is the general contractor.

Just under half or $2 million of the Andersons' gift to the hospital will create the James and Patricia Anderson Advanced Surgical Technology and Training Endowment Fund. It will fund ongoing training and continuing medical education for surgeons, anesthesiologists, interventionists, nurses, technicians and other members of the surgical team and the purchase of advanced equipment as it becomes available.

"I'm in the technology business and I like state-of-the-art technology in Grosse Pointe," said James Anderson in an email. "It doesn't matter the industry: health, auto or music — technology and data analytics are important and changing rapidly. I want my gift to be used for continuous improvement, not only the equipment and medical technology, but educating those people using the technology. The pace of change only gets faster every year. It's not one and done. Things advance. We need to advance with them."

The Grosse Pointe Shores residents' two daughters had four children at Beaumont Grosse Pointe, he said.
