A former employee of All Children's Hospital has filed a whistle-blower lawsuit in federal court accusing the hospital of overpaying its physicians in violation of anti-kickback laws. Barbara Schubert, a 60-year old Bradenton resident, worked at the hospital for more than a decade as director of operations for its doctors' practice. She contends that All Children's was so eager to hire doctors—ensuring a steady stream of patient referrals—that it paid them salaries far higher than was merited for their specialities.
