Can a Doctor or Physician be held Liable for giving Medical Treatment while Off-Duty?
First of all, a doctor or physician must owe a duty to their patient before they can be held liable for giving medical treatment while off-duty. In the U.S., a doctor has no affirmative duty to provide medical assistance to injured persons if they have not established a special relationship with the individual.
So, for example, if a doctor is off-duty having a meal in a restaurant and a person is injured, they do not actually have a duty to assist that person. If the doctor continues eating their meal, the injured person does not have a
medical malpractice claim against the doctor, even if they are harmed. This is because no special relationship has formed yet between the injured person and the doctor.
On the other hand, suppose that the off-duty doctor willingly and knowingly volunteers to assist the injured person. At this point a doctor-patient relationship has been formed. The doctor may then become liable if their medical assistance further injures the patient (for example, if they were
negligent during treatment). Or, they may become liable if they volunteer assistance and then abandon the treatment later.
