医疗意外是在正常的诊疗护理工作中,非出于医疗机构及其医务人员的故意或过失,而是由于不能预见的原因,导致患者出现不良后果的情形。其因具有不可预见性和医疗机构及医务人员无过错而与并发症及医疗事故相区别。若医疗机构及医务人员在诊疗护理活动中已根据当时的条件、情况,达到了当时的医疗水准,则我们应认定该不良后果是一种医疗意外,而非医疗事故。 Medical accidents are the result of normal medical treatment and care work, not because of the will or negligence of medical institutions and their medical staff, but because of unforeseen causes of adverse patient outcomes. It is distinguished from complications and medical incidents by its unpredictability and without fault of medical institutions and medical personnel. If medical institutions and medical staff have reached the prevailing medical standards according to prevailing conditions and circumstances at the time of medical and nursing activities, we should consider the adverse consequence as a medical accident rather than a medical incident.
