Thomas Boone Quaid: Bio Summary

Thomas Boone Quaid is a fraternal twin

The fraternal twins, Thomas Boone Quaid and his sister, Zoe Grace Quaid were born via a surrogate on November 8, 2007, in Santa Monica, California. As of 2024, they are 17 years old.

However, About 10 days after their birth, the newborns, Thomas Boone and his sister contracted staph infections and were quickly admitted to Cedars-Sinai Medical Center in Los Angeles. However, it was there that both children were given reportedly 10,000 units of Heparin blood thinner (twice!), instead of the 10 units prescribed — an overdose that nearly cost the kids their lives.

As His father, Dennis Quaid told the Los Angeles Times, no one called him or Buffington about the accident that made it impossible for their two babies’ blood to clot. It was not until they returned to the hospital to visit the twins the next day that they discovered this traumatic turn of events. “Our kids could have been dying, and we wouldn’t have been able to come down to the hospital to say goodbye,” he explained. But thanks to prayer and the diligent hospital staff, Quaid’s twins overcame the life-and-death ordeal.

Once Dennis’s twins Thomas Boone Quaid and Zoe Grace recovered from the accidental overdose of the blood thinner Heparin, His father and mother, Kimberly Buffington ultimately sued Baxter Healthcare Corp., the maker of the medication, in which they accused the company of failing to recall the drug after other infants died due to poorly labeled vials that spawned said medical mix-ups.

Thomas Boone’s parents also settled with Cedars-Sinai Medical Center for $750,000 after this mistake nearly killed their newborns.

After the hospital was also fined $25,000 by the California Department of Public Health, Thomas Quaid’s father told Theo Von and Matthew Cole Weiss’ podcast Allegedly (per People) that, in addition to an apology to all the families impacted, Cedars-Sinai vastly improved its protocol to ensure such deadly scares never happen again. “The hospital really stepped up and instituted a lot of patient safety that was very cutting edge and led the way with that,”

Thomas Boone Quaid’s father said. “So a lot of good things came out of it, and I think a lot of lives got saved because of that the drug companies, or the hospitals, actually put my face on the bottle to remind people for a time!”

Dennis Quaid explained that, while this “was the most frightening time of [their] lives,” they felt the strong need to “step up for it” to guarantee that no other children or parents would ever have to endure what his own kids went through.
