The types of injuries ER patients suffer depend on their medical condition and the type of ER malpractice. Examples include: A worsening of an injury or disease Injuries due to improper treatment An inability to treat or cure a preventable injury or disease because of delay, an improper diagnosis, or other reasons Adverse reactions to improper medications or treatments In the most tragic cases, an ER patient whose life should have been saved dies due to mistakes in the emergency room. Generally, ER facilities that accept patients are liable for medical malpractice if they fail to provide care in accordance with ER standard practices, and the improper care causes injuries or death.
