With the number of surgeries performed up 20 percent in the past three years, Riverview Medical Center opens the doors to phase one of a $15 million upgrade to its surgical facilities Monday.

Located in the third floor of the Blaisdell Pavilion and overlooking the Navesink River, the Red Bank hospital’s new “surgical day-stay” features 21 semi-private and two private rooms for patient recovery from same-day procedures, replacing a dormitory-style setup.

Due in September are two high-tech surgical suites, which will bring the number of operating rooms to 12 and complete the project. Hospital employees themselves contributed $374,000 to a capital campaign for the project, a spokesman said. (Click to enlarge)
