Among the acts or omissions that may potentially support a medical malpractice claim are the failure to properly diagnose a disease or medical condition, the failure to provide appropriate treatment for a medical condition, and unreasonable delay in treating a diagnosed medical condition. In some jurisdictions a medical malpractice action may be allowed even without a mistake from the doctor, based upon principles of informed consent, where a patient was not informed of possible consequences of a course of treatment and would have declined the medical treatment had proper information been provided in advance.
