In 1949, the "Community Memorial" Hospital Association purchased a tract in North Seattle. Northwest Hospital opened in 1960, as the city's northernmost hospital. In 1965 the hospital acquired a radioisotopemagna scanner, and over the rest of the 1960s they established a comprehensive rehabilitation program, an inhalation therapy department, a program for hearing disorders, and a stroke center. In 1970, they were the firstSeattle hospital with a birth clinic offering the use of a single "birth suite" for labor, delivery, recovery, and postpartum care. The 1970s saw physical expansion of the emergency department, the opening of a department of nuclear medicine, and the 1977 establishment of the Northwest Hospital Foundation. Physical expansion continued in the 1980s with a new tower building. In 1985, Northwest Hospital physicians pioneered the ultrasound-guided installation of a radioactive "seed" implant to treat prostate cancer. In 1993 they were the region's first hospital to offer the non-surgical gamma knife technique of treating brain tumors. In the 2000s, the emergency department expanded yet again, and Northwest continued to adopt pioneering technologies such as minimally invasive surgical techniques, DynaCTangiogram technology, and robotic surgery. They began to use electronic medical records and bedside medication reconciliation in 2007; that same year they converted to all-digital mammography. A sleep center opened in 2008. In 2011, work began on the region's first proton beam therapy center for cancer treatment. 2009 saw the introduction of hyperbaric oxygen therapy. Physical expansion also continued with the enlargement of the hospital's surgical facility in 2010.
After the UW Medicine merger, Northwest remained a separate nonprofit, tax-exempt entity.
