The current UK quality assurance guidelines for radiologists in the NHS breast screening programme require those reporting screening mammograms to read a minimum of 5000 cases per year. We aimed to review the evidence for this and to assess whether there was justification for lowering the required level. A literature search was conducted to identify relevant studies where accuracy of reporting mammograms was related to reading volume. Three of the five studies reviewed suggested a positive association between reading volume and sensitivity, but there were few data on volumes above 5000 cases per year. The available evidence did not provide any basis for reducing the threshold volume. Further work is needed, in a UK or European setting, to study the relationship between reading volume and accuracy at higher volume levels and also the separate effects of reading volume and reading experience.
英国国家医疗服务体系（NHS）乳房筛查项目目前针对放射科医生的质量保证指南要求，解读乳房筛查X光片的人员每年至少要阅读5000个病例。我们旨在复查这一要求的相关证据，并评估降低该要求水平是否合理。我们进行了文献检索，以确定将乳房X光片报告的准确性与阅读量相关联的相关研究。所审查的五项研究中有三项表明阅读量与敏感度之间存在正相关，但关于每年阅读量超过5000个病例的数据很少。现有证据并未为降低阈值阅读量提供任何依据。需要在英国或欧洲环境下开展进一步工作，以研究更高阅读量水平下阅读量与准确性之间的关系，以及阅读量和阅读经验各自的影响。
