Aim

This study aims to determine the incremental cost of having a TBI in older adults, as well as the incremental cost of being of older age in patients with TBI.

Method

Incremental costs were assessed for both hospital and the period of one year post-injury. Data on patients aged 65 years and older with TBI were retrieved from a database of all transport-related trauma admissions in Belgium between 2009 and 2011. Each case was matched to two similar controls who were (1) older without TBI or (2) younger with TBI. Incremental costs were estimated by comparing cases with controls using both simple and multiple regression.

Results

The incremental cost of TBI at older age was most pronounced for those with skull fracture and intracranial injury (hospital: increase with multiplicative factor of 1.39, 95%CI [1.14;1.69] ; one-year: 1.45, 95%CI [1.17;1.80]). The incremental cost of being of older age was highest for patients older than 75 years (hospital: 1.27, 95%CI [1.09;1.47] ; one-year: 1.74, 95%CI [1.47;2.05]).

Conclusion

The incremental costs estimated in this study are valuable for further health economic research and policymaking in response to the changing demographics of traffic participants.

65岁及以上成年人与运输相关的创伤性脑损伤和年龄增加的成本增加

目标

这项研究的目的是确定老年人中TBI的增量成本，以及TBI患者中老年的增量成本。

方法

评估医院和受伤后一年期间的增量成本。从2009年至2011年比利时所有运输相关的创伤住院数据库中检索了65岁及65岁以上患有TBI的患者的数据。每例均与两个相似的对照组相匹配，他们分别是（1）没有TBI的年龄较大或（2）年龄较小的年龄与TBI。通过使用简单回归和多元回归将病例与对照组进行比较来估算增加的成本。

结果

对于颅骨骨折和颅内损伤的患者，TBI在老年时的增加费用最为明显（医院：乘以1.39，95％CI [1.14; 1.69]的增加；一年：1.45，95％CI [1.17; 1.80]）。75岁以上患者的老年增加成本最高（医院：1.27，95％CI [1.09; 1.47]；一年：1.74，95％CI [1.47; 2.05]）。

结论

这项研究中估计的增量成本对于响应交通参与者不断变化的人口状况的进一步卫生经济研究和政策制定非常有价值。
