More detailed information about the Horizon Tower, taken from WUSA9.com, press release:

Adventist HealthCare Shady Grove Medical Center has opened a new patient tower aimed at modernizing emergency and critical care for the region.  The Horizon Tower began receiving patients Sunday, June 14, marking a major expansion at the Rockville hospital. Emergency services moved into the new space early that morning, followed by a coordinated transition of intensive care and other patients later in the day. The six-story addition features a redesigned emergency department, advanced intensive care units and updated rooms for stroke patients. Hospital leaders say the new layout is designed to improve speed, safety and patient experience.

The emergency department includes 38 treatment bays with glass doors intended to enhance privacy and reduce noise. Imaging equipment, including X-ray and CT scanners, is built directly into the unit to help cut down on wait times, while multiple nurses’ stations are positioned to offer better visibility of patients. The tower replaces 76 older critical care rooms but does not increase the hospital’s overall capacity. Instead, officials say the focus is on improving efficiency, staff workflow and overall comfort for patients and families.

The more than 150,000-square-foot building was designed with input from caregivers and incorporates lessons learned during the COVID-19 pandemic. Features include larger negative pressure rooms and the ability to convert entire units for infectious disease care if needed. The space also uses low- and no-touch technology and materials aimed at improving infection control. Designers also emphasized natural light and access to outdoor space. An outdoor patio for intensive care unit families provides a place for visitors to step away while staying close to loved ones receiving care.  The Horizon Tower includes a rooftop helipad that has been operational since 2025, along with a lighted column that will change colors to mark holidays and health awareness events.
