Thomas Boone Quaid’s birth brought joy and terror on November 8, 2007, in Santa Monica, California. The celebration of his arrival with twin sister Zoe Grace Quaid quickly turned into every parent’s worst nightmare.
A devastating medical error struck after the twins developed severe staph infections that sent them to Cedars-Sinai Medical Center. The babies received 1,000 units of Heparin instead of the prescribed 10 units of Hep-Lock—an overdose that put their lives at risk. Medical teams worked frantically for 41 grueling hours to save the newborns. The twins pulled through after spending two weeks in intensive care, making a full recovery.
This piece tells the complete story of Thomas Boone Quaid, from his dramatic first days to his life as Dennis Quaid’s son. The near-tragedy inspired his parents to become passionate champions for patient safety, which led to nationwide changes in hospital protocols.
The Birth of Thomas Boone Quaid and His Twin Sister
Born via gestational surrogacy
Dennis Quaid and Kimberly Buffington chose gestational surrogacy to start their family after years of trying. The twins were their biological children, conceived with their own sperm and eggs. A surrogate mother carried the pregnancy, which helped them overcome their fertility challenges.
The special morning arrived on Thursday, November 8, 2007. Thomas Boone Quaid entered the world at 8:26 a.m., weighing a healthy 6 pounds, 12 ounces. The birth happened at St. John’s Health Center in Santa Monica, California with careful medical supervision. The couple brought their twins home after three days and looked forward to settling into family life.
Zoe Grace Quaid: His twin and lifelong companion
Zoe Grace Quaid arrived just two minutes later at 8:28 a.m., weighing 5 pounds, 9 ounces. The twins formed an unbreakable bond right from the start, despite their small size difference.
Their parents’ joy showed in their heartfelt statement: “God has definitely blessed us”. These words captured their deep gratitude after such a challenging experience to parenthood. The twins would soon face their first life challenge together, though they were born just minutes apart.
A long-awaited joy for Dennis Quaid and Kimberly Buffington
Thomas and Zoe’s arrival marked the end of an emotional fertility experience for the couple. Kimberly had suffered through five consecutive miscarriages. Each loss added to their heartbreak. The surrogate who carried the twins had also experienced a miscarriage during an earlier attempt.
“It was a very difficult time for the Quaids,” a source close to their story shared. The twins’ birth at 36 weeks gestation represented more than just a delivery – it was their triumph after years of hope and persistence.
Dennis was 53 when he became a father again. He already had a 15-year-old son, Jack Henry, from his previous marriage to actress Meg Ryan. The twins completed Dennis and Kimberly’s dream of building a family together since their 2004 marriage.
The Heparin Overdose Incident: A Life-Threatening Error
The birth of Thomas Boone Quaid and his sister brought joy that quickly turned into a parent’s worst nightmare. Their admission to Cedars-Sinai Medical Center for a staph infection treatment marked the beginning of a terrifying ordeal.
What went wrong at Cedars-Sinai Medical Center
A series of devastating errors unfolded on November 18, 2007. Two pharmacy technicians delivered 100 vials of high-concentration heparin to the pediatric unit by mistake. The medication contained 10,000 units per milliliter instead of the needed 10 units per milliliter for infants. Thomas Boone and Zoe Grace received two doses of this dangerous concentration about eight hours apart.
The life-threatening error happened because adult and pediatric versions of heparin had almost identical blue labels and bottle shapes. The core team failed to check the medication’s concentration. This represented a complete breakdown in safety protocols.
Immediate medical response and critical hours
Medical staff rushed to give the twins an antidote to help their blood coagulate after discovering the error. Dennis Quaid later described that the heparin “basically turned their blood to the consistency of water, where they had a complete inability to clot”. The crisis lasted 41 harrowing hours. Blood oozed from tiny puncture wounds on the babies’ feet.
Terror struck when blood from Thomas’s umbilical area “squirted across the room, about six feet and landed on the wall”. Both twins developed bruises from bleeding beneath their skin.
Public reaction and media coverage
TMZ.com broke the news on November 20, two days after the overdose. The Quaids felt betrayed by the hospital, especially since their family learned about the crisis from media reports rather than direct communication.
The California Department of Public Health fined Cedars-Sinai $25,000 for the violations. Notwithstanding that, the incident raised awareness about medication errors. Dennis Quaid pointed out these errors kill about 100,000 people in American hospitals each year.
From Crisis to Advocacy: The Quaid Foundation
Standing beside the tiny isolettes where Thomas Boone and Zoe Grace lay recovering, Dennis Quaid made a powerful vow: to ensure what happened to his children would never happen to another family. “I thought, ‘They’re 12 days old, and they’re going to change the world,'” Quaid recalled after the twins had stabilized.
Why Dennis Quaid and Kimberly Buffington took action
The Quaids were deeply disturbed when they found that three infants had died at Methodist Hospital in Indianapolis from a similar heparin overdose just a year earlier. The situation became worse when they learned that Baxter Healthcare Corporation had redesigned the packaging but hadn’t recalled existing bottles. This decision made Quaid furious. “Companies recall dog food!” he exclaimed.
The couple started The Quaid Foundation in 2008 to raise the standard of patient medical care. A shocking statistic drove their mission: about 100,000 deaths happen each year from preventable medical errors, and hospital infections claim another 100,000 lives.
The mission of the Patient Safety Movement Foundation
The foundation began by spreading public awareness about medical mistakes. They later joined forces with the Texas Medical Institute of Technology (TMIT), a private, non-profit medical research organization led by Dr. Charles Denham.
Their collaboration brought forth “Story Power”—what they called the “secret weapon” to fight defective systems and defensive mindsets that lead to devastating medical errors. Personal narratives became their tool to create meaningful changes in hospital practices.
Impact on hospital safety protocols
The Quaids became strong supporters of the National Quality Forum’s “Safe Practices for Better Healthcare,” which outlines 34 practices for hospitals to implement nationwide. Dennis contributed by co-authoring the patient section of this crucial report.
The couple created the documentary “Chasing Zero: Winning the War on Healthcare Harm,” which aired on Discovery Channel. They sent free copies to more than 5,700 hospitals across America to encourage engagement.
Their advocacy helped advance essential safety technologies such as bedside bar coding, electronic record keeping, and computerized physician-order entry systems. Dennis praised Cedars-Sinai when they implemented these systems as part of their settlement, despite the difficult circumstances.
The foundation continues to champion simple yet effective safety measures like hand-washing protocols and medication bar coding that could save countless lives.
Growing Up in a Celebrity Family
Thomas Boone Quaid and his sister Zoe experienced a unique childhood. They grew up with a Hollywood star father yet led a surprisingly normal life beyond their dramatic early days.
Balancing fame and privacy
Thomas Boone and Zoe Grace Quaid‘s parents made a conscious choice to shield them from the spotlight. They stayed away from sharing personal details on social media to give their children a normal upbringing. The twins learned about their father’s fame in an interesting way. They watched him in The Parent Trap and responded with a simple “Oh, it’s my dad,” without doubt not grasping their dad’s celebrity status.
Relationship with half-brother Jack Quaid
Thomas‘s bond with his older half-brother Jack plays a vital role in the Quaid family. Jack, now 32, came from Dennis’s marriage to actress Meg Ryan. The 15-year age gap never stymied their connection. Dennis shared in a February 2008 interview, “It’s fantastic for Jack having a little brother and sisters now.” Jack built his own acting career successfully through roles in The Boys and The Hunger Games – not riding on his father’s fame. He thought about changing his last name but ended up deciding: “I like my last name. I’ll keep it.”
How Dennis Quaid approaches parenting
Dennis sees himself as a “dorky dad” who can be “loud sometimes.” His approach to parenting stays simple and direct: “I tell my kids to find something you love to do, then figure out a way to get paid for it. I don’t push them either way. They are who they are.” The near-loss of the twins changed his view on fatherhood completely. “It took my focus off myself, which is always good for an actor because actors are so self-involved,” he explained. His love for being a father shows clearly. “I love being a dad. I really do. I think I’m a good dad,” Dennis said in 2023, adding proudly, “It turned out so far so good. Jack really turned out well. I’m really proud of him, and Thomas and Zoe too.”
