Bone mineral density measurements have been criticized on the grounds that they are not a worth-while screening tool. In this paper we argue that bone mineral measurements can be an efficient diagnostic tool even if they are not of proven value for screening. There is complex relationship between the costs of a measurement, the intervention and the predictive value of the test all of which must be accounted for when assessing the value of a bone density measurement. For bone density measurements to be used for screening, a wider evaluation needs to be undertaken compared with that for their use as a diagnostic tool. We address some common objections, for example, that low compliance with screening would undermine efficiency, and show that these are not relevant. Evaluations of screening need to address issues that are likely to affect efficiency.
骨密度测量一直受到批评，理由是它们不是一种有价值的筛查工具。在本文中，我们认为骨密度测量即使对筛查没有经证实的价值，也可以成为一种有效的诊断工具。测量成本、干预措施和检测预测价值之间存在复杂的关系，在评估骨密度测量的价值时，所有这些都必须考虑在内。与用作诊断工具相比，要将骨密度测量用于筛查，需要进行更广泛的评估。我们回应了一些常见的反对意见，例如，筛查依从性低会破坏效率，并表明这些并不相关。筛查评估需要解决可能影响效率的问题。
