Comparison of healthcare costs for youth with mild traumatic brain injuries (TBIs) to costs in a matched cohort of children without TBI in the 3 years following injury.
This study used a prospective cohort design with 3-year follow-up. Costs were examined using the well-established two-step model and controlling for potential confounding variables.
Four-hundred and ninety subjects from a large health maintenance organization, 14 years old or younger, who sustained a mild TBI in 1993, were identified using computerized records. For each youth with mild TBI, three control subjects were selected (n = 1470), matched on age, sex and enrolment at the time of injury.
Not applicable.
TBI exposure was associated with an increase in the proportion of subjects who had non-zero medical costs in all categories examined and a 75% increase in mean total costs. Presence of psychological distress was also associated with increased proportion of subjects with costs in all categories examined and was associated with an approximate doubling of mean total costs.
Mild TBI and psychological distress were each associated with significant increases in healthcare costs in an HMO setting.
比较轻度创伤性脑损伤（TBI）青少年与未患TBI的匹配儿童队列在受伤后3年的医疗费用。
本研究采用前瞻性队列设计，随访3年。使用成熟的两步模型检查费用，并控制潜在的混杂变量。
利用计算机记录，从一个大型健康维护组织中识别出1993年遭受轻度TBI且年龄在14岁及以下的490名受试者。对于每一名患有轻度TBI的青少年，选取三名对照受试者（n = 1470），根据受伤时的年龄、性别和参保情况进行匹配。
不适用。
在所有检查类别中，TBI暴露与医疗费用非零的受试者比例增加相关，且平均总费用增加75%。心理困扰的存在也与所有检查类别中费用较高的受试者比例增加相关，且与平均总费用增加近一倍相关。
在健康维护组织环境中，轻度TBI和心理困扰均与医疗费用显著增加相关。
