In a previous article in this series, published in 2004, the authors reviewed the medical literature for evidence on the relationship between self-referral and the utilization of imaging. That evidence demonstrated that self-referral led to substantially higher levels of utilization with its attendant increases in cost and the exposure of patients to unnecessary radiation. Since then, much new information has been published on this controversial subject. In this article, the authors update their previous article by summarizing all the recently published material. Once again, the evidence clearly indicates that self-referral results in the overutilization of imaging. Because radiologists have an important stake in the matter, it behooves them to be familiar with this recent evidence so they can bring it to the attention of policymakers in their areas.
在本系列2004年发表的上一篇文章中，作者回顾了医学文献，以寻找有关自我转诊与影像检查利用之间关系的证据。该证据表明，自我转诊导致影像检查的利用率大幅提高，随之而来的是成本增加以及患者遭受不必要的辐射。自那时以来，关于这个有争议的话题已经发表了许多新信息。在本文中，作者通过总结所有最近发表的材料来更新他们之前的文章。证据再次清楚地表明，自我转诊会导致影像检查的过度使用。由于放射科医生在这件事上有重要利害关系，他们理应熟悉这些最新证据，以便能够将其提请所在地区的政策制定者注意。
