探討因跌倒意外事件入急診部看診的比率及其患者之外傷嚴重度的影響因素。方法：本研究於2005年1月至12月期間，以問卷訪問因意外跌倒而到中部某醫學大學附設醫院急診部就診的患者，分析跌倒患者的人□學資料、跌倒原因、及其外傷嚴重度。結果：有效樣本數為361人，平均年齡為35.5±1.4歲，外傷嚴重度分數(ISS)平均值為7.0±0.5分，患者死亡率為1.1%。外傷嚴重度與跌落高度、年齡別、跌倒方式、骨折與否、處理結果及外傷嚴重度分數之間呈現顯著正相關。結論：當患者從高處跌落（非平面跌倒）時，通常外傷嚴重度會較高，且患者的外傷嚴重度與骨折及處理結果呈現顯著相關性。因此，在急診部處理跌倒患者時，患者外傷嚴重度分數是一項良好的指標，可以提醒醫師去注意高危險群，以避免這些患者產生較差的預後，並增進急診醫療品質。
Purpose: This study is to explore the rate of fall accidents and the factors contributing to the traumatic severity of the injuries. Method: A questionnaire was administered to fall patients visiting an ER in a medical university hospital in central Taiwan between January 2005 and December 2005. Medical recorded were also studied to collect demographic data, causes of falls, and Injury Severity Score (ISS). Results: In total we collected 361 qualified samples. The average of age of victims was 35.5±1.4, average ISS 7.0±0.5, and mortality 1.1%. Traumatic severity was significantly and positively correlated with fall height, age group, fall type, fractures, treatment outcome, and ISS. Conclusion: As these patients fall from a high position (non-planar type), they always get a severe condition, and the ISS is significant related to these patients’ fractures and treatment outcomes. Therefore, the ISS is an excellent indicator of traumatic severity to indicate that particular care should be paid to those with higher scores to avoid bad prognoses and promote the quality of emergency medical service.
