Nonabandonment means encouraging communication, showing genuine concern, being available, keeping promises, and ensuring the patient's continuity of care. It goes beyond the usual standards of care that are followed for avoiding legal negligence. Nonabandonment prevents the attitude that nothing can be done and is particularly applicable to those who are near the end of their lives. Nutrition support can reinforce this philosophy.
