Common Emergency Room Mistakes

Emergency Room Malpractice Injury

Common injuries resulting from emergency room malpractice may include:

ER Medical Malpractice Lawsuits

The Emergency Medical Treatment and Active Labor Act, also referred to as COBRA, dictates that any patient who visits an emergency room for evaluation must be given an appropriate medical screening to determine whether they are suffering from an emergency medical condition. If they in fact are an emergency state, the hospital is obligated to provide the patient proper treatment.

Should a hospital fail to provide appropriate care and an injury results, a plaintiff and family may file an emergency room malpractice lawsuit and recover medical expenses, loss of wages, long-term disability, long-term care expenses, rehabilitation costs, as well as damages associated with pain and suffering.

A Voice for Those who have suffered 

Why are these cases important?

 When management or individuals fail to provide a sufficient level of care, victims may seek legal recourse and file suit against the negligent parties. Medical malpractice lawsuits improve the quality of healthcare by holding physicians and hospitals responsible when they fall below a professional standard of care.

(Cincinnati, Ohio):  Confidential settlement for a family due to a wrongful death. An emergency room physician failed to recognize the common symptoms associated with bowel obstruction and prescribed a contraindicated medicine of GoLytley.  The patient died at home the day of discharge after taking the medication. The case against the emergency room physician was resolved by settlement following extensive discovery. The settlement was paid to the spouse and surviving adult children for the loss of their mother. While no amount of money could bring back their mother, the case provided answers and held the hospital accountable.


$910,000 Settlement.

(Cincinnati, Ohio):   Joe Lyon was second chair in a case involving the failure of a physician to promptly communicate a positive breast cancer result to a patient. As a result of the delay, the cancer progressed from in situ carcinoma to stage 3B with lymph node involvement. The treatment required mastectomy and radiation/ chemotherapy rather than a simple excision. The case settled after extensive discovery. The defense argued: “the patient should have called the physician.” The settlement provided recovery for suffering through a misdiagnosis and the loss of a spouse and a mother. While the settlement cannot bring this wonderful woman back, it helped her family move forward with life’s challenges and encouraged  future accountability.
