On November 18, 2007, hospital staff mistakenly gave Quaid's ten-day-old twins a dosage of heparin (a blood thinner) that was 1,000 times the common dosage for infants. The babies recovered, but Quaid filed a lawsuit against the drug manufacturer, Baxter Healthcare, claiming that packaging for the two doses of heparin are not different enough. In May 2008, the Quaids testified before the United States House Committee on Oversight and Government Reform, asking U. S. Congress not to preempt the right to sue drug manufacturers for negligence under state law. This incident led Quaid to become a patient-safety advocate, producing a series of documentaries on preventable medical errors that aired on the Discovery Channel as well as co-authoring a medical journal article addressing the positive influence of patient stories in motivating change in healthcare. The first documentary, Chasing Zero: Winning the War on Healthcare Harm, aired on the Discovery Channel in 2010, and the second documentary, Surfing the Healthcare Tsunami: Bring Your Best Board, aired on the Discovery Channel in 2012.
