因果关系是侵权成立的要件之一,能否证明侵权行为与损害之间存在因果关系,关系到原告能否主张损害赔偿。但在低治愈率疾病的不作为医疗侵权上,根据传统因果关系理论,因果关系的证明存在困难,本文就低治愈率疾病的不作为医疗侵权的因果关系做了论证,并借鉴国外新理论,希冀对我国该类侵权找出解决办法。 Causality is one of the most important elements of the infringement. Whether it can prove the causal relationship between the infringement and the damage relates to whether the plaintiff can claim damages. However, in the low cure rate of medical malpractice, according to the traditional causation theory, the causation is proved to be difficult. This article demonstrates the causal relationship between low cure rate and non-medical tort, and draws lessons from the new theory of foreign countries, We hope to find a solution to this kind of infringement in our country.
