Volume-outcome relationships in vascular surgery have become increasingly relevant in recent years. At the individual surgeon level, increased experience has been linked with improved patient outcomes after volume-outcome and learning curve analyses. At the hospital level, further analyses have generally shown a similar relationship linking the busier hospitals with improved outcomes. However, is this relationship sufficient and robust enough to support important health care delivery decisions regarding centralization of care? In England, such information has helped to shape the vascular surgery reorganization process in London. The following discussion presents the advantages and disadvantages of the practical use of such information.
近年来，血管外科学中的量效关系变得越来越重要。在个体外科医生层面，通过量效和学习曲线分析，经验的增加与患者预后的改善相关。在医院层面，进一步的分析通常表明，与较繁忙的医院相关的类似关系可以改善结果。然而，这种关系是否足够充分和稳健，足以支持有关护理集中化的重要医疗服务决策？在英国，此类信息有助于塑造伦敦的血管外科学重组过程。以下讨论介绍了实用此类信息的优缺点。
