If a patient is harmed during diagnosis or treatment and the medical institution or its staff were at fault, the institution is liable to compensate. Medical liability is fault-based: you must show the treatment was negligent and that it caused the harm.

患者在诊疗活动中受到损害，医疗机构或者其医务人员有过错的，由医疗机构承担赔偿责任。医疗损害责任以过错为原则，需证明诊疗行为存在过错且与损害之间有因果关系。
