Dennis Quaid and his wife Kimberly reached a settlement with Cedars-Sinai Medical Center for $750,000 over a medication error that nearly killed the couple's twin infants, according to papers filed in Los Angeles County Superior Court. Nurses at the hospital mistakenly gave twins Thomas Boone and Zoe Grace 1,000 times the recommended dose of the blood thinner heparin. Hospital officials have cited at least three separate safety lapses that led to the overdoses. Cedars-Sinai Medical Center was not sued, although the hospital was described in a court filing as a "potential defendant."
