外傷性腦受傷病患之存活因素分析
目的：根據 2007 年行政院衛生署統計，事故傷害是臺灣居民的第五位死因。其中，外傷性腦受傷是導致意外傷害死亡之主因。而台灣地區自 1997 年實施 騎機車強制配戴安全帽的政策後，顯著降低了外傷性腦受傷病患的致死率。
但許多文獻顯示，外傷性腦受傷會對患者後續存活情形產生負面影響。因此
，本篇研究目的為探討影響外傷性腦受傷患者存活的相關預後因子。
方法：本研究對象包括從 2003 年至 2006 年期間由「外傷性腦受傷資料庫」所收集的 14,277 位病患，利用身分証字號連結「行政院衛生署」 2003 至 200 7 年死因檔資料庫，確認研究個案其死亡時間紀錄。以 Kaplan-Meier method 分析外傷性腦受傷病患受傷後一年內存活情形並使用比例式危險模式估計各 預後因子與存活情形之關係。
結果：結果顯示進入分析的 13,637 位外傷性腦受傷患者中，有 1,249 位病患 在受傷後一年內死亡，存活率為 90.84% ，其中有 64.6% 的病患在受傷後第一 個月內死亡。昏迷指數 (GCS) 、年齡、性別、跌倒、神經障礙、顱骨骨折與 顱內出血等預後因子與受傷後一年內死亡的風險分布有關，均達統計上顯著 意義。
結論：總結以上，本研究結果發現外傷性腦受傷病患其昏迷指數 (GCS) 等各 項傷害特徵的差異在受傷後一年內的死亡風險中的確扮演了關Prognostic factors of traumatic brain injury survivors
Purpose ： In 2007, injuries were the fifth leading cause of death in Taiwan. Moreover, the major subtype of injury is Traumatic brain injury (TBI). Although Taiwan''s implementation of the mandator y helmet law since 1997 has significantly reduced TBI fatalities, most studies have found that TBI negative ly impacts long-term survival. The aim of the study was to identify prognostic factors for survival in patien ts after TBI.
Method ： The data of patients with TBI were extracted from the Head Injury Registry between 2003 and 2006. Using the data as the sampling frame, 14,277 patients and the dataset of death registration for the De partment of Health (DOH) between 2003 and 2007 were linked by same ID no. Kaplan-Meier estimates of the cumulative proportion of deaths that occurred within 1 year wer computed for each risk factor. Prognos tic factors influencing the survival period were examined by Cox proportional hazard model.
Result ： Of the 13,637 eligible patients selected for participation, 1,249 were deceased within 1 year and t he survival rate was 90.84%. About 64.4% of the death patients occurred within the first month. Factors in cluding Glasgow coma scale (GCS) score, age, sex, fall, cranial nerve lesion, fracture of skull, and intracra nial hemorrhage, may play an important role in predicting the outcome of traumatic brain injury.
