Northwest Medical Center of Benton County is the newest and most modern hospital located in Bentonville, Arkansas. The tertiary care facility is a part of Northwest Health System and offers a full range of healthcare services to the communities of northwest Arkansas, southwest Missouri and northeast Oklahoma. Northwest Medical Center was opened in 2003 as a replacement hospital for Bates Medical Center, which was established in 1942 as Benton County’s first hospital. The key services of the new 125-bed facility include cardiac services, cardiac catheterization, cardiac rehabilation, open heart surgery, neurosurgery, digital imaging, orthopedics, women's and children's care, and senior services. The hospital features Arkansas' first completely digital imaging department. A separate, on-site women's diagnostic center offers digital mammography, bone density and ultrasound testing. The Agility Center, which houses wellness and outpatient rehabilitation units, offers a state-of-the-art swimming pool with aquatic therapy machines and an outpatient physical therapy facility. A recent addition in the hospital was the Northwest Medical Plaza, a 69,000 square foot, three-story building. Opened in 2004, it houses the outpatient ambulatory surgery center and a variety of medical offices and clinics. Aside from their childbirth classes, the medical center has aquatic programs, strength training, and volunteer programs. Northwest Medical Center of Benton County is accredited by the Joint Commission on Accreditation of Healthcare Organization (JCAHO).
