PeaceHealth is a Washington corporation that operates six hospitals, medical groups, a chemical dependency program, health care joint ventures, and other services in southeast Alaska, northwest Washington, southwest Washington/northwest Oregon, Oregon's Willamette Valley, and Oregon's central coast. System headquarters are in Bellevue, Washington.
PeaceHealth donated $50,000 to Oregon Ballot Measure 50 in 2007.
PeaceHealth was sued by McKenzie-Willamette Hospital in 2003. McKenzie claimed that PeaceHealth had broken federal antitrust laws by committing monopolization, attempted monopolization, conspiracy to monopolize, tying, and exclusive dealing and that it had also broken state laws by committing price discrimination and intentional interference with prospective economic advantage.
A jury awarded McKenzie $5.4 million in damages, which the district court trebled for a final award of $16.2 million. The district court also awarded McKenzie $1,583,185.57 in attorneys’ fees, costs, and expenses. The 9th U.S. Circuit Court of Appeals in September 2007 overturned the jury's verdict and sent the case back to the trial court in U.S. District Court in Portland, Oregon.
