Abstract

OBJECTIVES

To examine trends in the use of diagnostic CT in aggregate and for 4 major body regions (abdomen/pelvis, head/neck, chest, and spine) in an 11-year US nationwide analysis.

METHODS

We summarize records from a large, mostly fee-for-service insurance claims database from 2000 to 2011.

RESULTS

Rates of diagnostic CT have increased substantially from 2000 to 2011; however, changes in rates are disparate for different age groups and body regions. As others have shown, there has been a notable increase in use of diagnostic CT from 2000 to 2011. However, from 2009 to 2011, diagnostic CT studies of the chest, abdomen/pelvis, and head/neck have leveled off or decreased, whereas CTs of the spine show a continued increase in many groups.

CONCLUSIONS

In general, the increase in the rate of CT study performance has slowed, whereas spine CT continued to escalate. Future research should consider whether the increase in use of spine CT leads to a benefit that outweighs the risk associated with the increased population-level cancer risk.

摘要

目的

通过对美国全国范围内 11 年的数据分析，研究总体及腹部/骨盆、头颈部、胸部和脊柱 4 个主要身体部位诊断 CT 使用的趋势。

方法

我们对 2000 年至 2011 年来自一个大型、主要以按服务收费为基础的保险索赔数据库中的记录进行了总结。

结果

从 2000 年到 2011 年，诊断 CT 的使用率大幅上升；然而，不同年龄组和身体部位的变化率却存在差异。正如其他人所表明的那样，从 2000 年到 2011 年，诊断 CT 的使用量显著增加。然而，从 2009 年到 2011 年，胸部、腹部/骨盆和头颈部的诊断 CT 研究已经趋于平稳或减少，而脊柱 CT 在许多人群中仍持续增加。
