received the largest donation in its history: $73.9M from Jack R. MacDonald. The same year, its Research Institute received a $3M donation from the BMGF for an Infant Breathing Support Invention. In 2017 the hospital had a total of 403 beds. In 2018, the hospital broke ground on a new 310,000-square-foot addition to the hospital. The new nine floor addition features eight new operating rooms, two cardiac catheterization labs, 20 inpatient rooms, a new outpatient clinical space for the oncology and hematology center and an outpatient infusion center. The new addition will cost around $400 million and open up in 2022. In 2019, the Seattle Center for Infectious Disease Research was absorbed by the SCRI. In November 2020, Seattle Children's launched Seattle Children's Therapeutics, a nonprofit therapeutics development enterprise devoted to envisioning next-generation therapies for pediatric diseases. Dwayne "The Rock" Johnson also collaborated with Microsoft and billionaire Bill Gates to donate Xbox Series X consoles to the Seattle Children's along with 19 other children's hospitals throughout the country. Controversy In 2015 the hospital warned the public that due to its improper sterilization of surgical equipment, around 12,000 children and young adults treated there since 2010 were at risk of infection from bacteria or blood-borne viruses, including hepatitis B and C and HIV; it had issued a similar warning two years earlier. From 2001 on, it was revealed that a strain of deadly mold in the air handling systems of operating rooms (Aspergillus) was detected by hospital administrators. The mold caused 14 infections and 6 deaths. In 2018 the mold was revealed and hospital staff agreed to clean up the mold. HEPA filters were installed and operating rooms were reopened in July that year. In November 2019, mold allegations again resurfaced when an infant tested positive for a mold infection. In early 2020, the health inspectors from the State of Washington came in and questioned hospital authorities on why HEPA filters were not installed in the ORs. The mold has led to a lawsuit. The move follows a pledge that the hospital would undertake a ‘rigorous’ review following the departure of Dr. Ben Danielson. Awards In 2016, it was ranked as the 5th best children's hospital in America by U.S. News & World Report and was ranked #4 in nephrology, #6 in cancer, #5 in neonatology, #13 in gastroenterology and GI surgery, #11 in pulmonology and #9 in neurology and neurosurgery.
