OBJECTIVE To provide nationally representative estimates of adults with traumatic brain injury (TBI) and identify clusters of individuals with TBI who follow similar perceived health trajectories using group-based trajectory modeling. PARTICIPANTS Adults (≥18 years old) from panels 9-19 (2004-2015) of the Medical Expenditure Panel Survey (MEPS) who experienced a TBI (n = 949). DESIGN Data from MEPS, a nationally representative database of noninstitutionalized individuals in the USA, were used to 1) produce a national annual estimate of adults with TBI and 2) identify subgroups of patients with TBI who followed different general and mental health trajectories. MAIN MEASURES Perceived general health (PGH), perceived mental health (PMH). RESULTS On average, 502 adults per 100,000 noninstitutionalized US adults experienced a TBI annually, and about one million adults are living with a TBI. Three distinct trajectory groups were identified in models of both perceived general health (PGH) and perceived mental health (PMH). TBI type, sex, and persistent disability predicted assignment to a group in the PGH model. TBI type, sex, age, insurance status, family poverty status, and persistent disability predicted assignment to a PMH trajectory. CONCLUSION Referrals and early-intervention resources should be distributed to individuals with increased risk of following low PGH and/or PMH trajectories.

成人外伤性脑损伤后的感知健康：基于组的轨迹模型（GBTM）分析。

目的提供基于全国代表性的成年人脑外伤（TBI）估计值，并使用基于群体的轨迹模型来识别遵循相似的感知健康轨迹的TBI个体群。参与者来自医疗支出小组调查（MEPS）的小组9-19（2004-2015）中经历过TBI的成人（≥18岁）（n = 949）。来自MEPS的DESIGN数据是美国非机构化个体的全国代表数据库，用于1）对TBI成人进行全国年度评估，以及2）确定遵循不同总体和精神健康轨迹的TBI患者亚组。主要指标感知总体健康（PGH），感知心理健康（PMH）。结果平均每年，每100,000个非机构化的美国成年人中就有502名成年人经历过TBI，大约一百万成年人患有TBI。在感知的总体健康（PGH）和感知的心理健康（PMH）模型中确定了三个不同的轨迹组。在PGH模型中，TBI类型，性别和持续性残疾会预测分配给某个群体。TBI的类型，性别，年龄，保险状况，家庭贫困状况和持续残疾预测为PMH轨迹。结论应将转诊和早期干预资源分配给因遵循低PGH和/或PMH轨迹而增加风险的个人。保险状况，家庭贫困状况和持续残疾预测到PMH轨迹。结论应将转诊和早期干预资源分配给因遵循低PGH和/或PMH轨迹而增加风险的个人。保险状况，家庭贫困状况和持续残疾预测到PMH轨迹。结论应将转诊和早期干预资源分配给因遵循低PGH和/或PMH轨迹而增加风险的个人。
