目的：探討住院病人院內心臟驟停(in-hospital cardiac arrest, IHCA)的預測因子。

方法：收集一般病房經歷IHCA與非IHCA的230名病人進行病歷對照研究，數據收集包括人口統計學特徵、疾病診斷、實驗室數據和生理參數，使用t檢定、卡方和邏輯斯迴歸進行分析。

結果：研究結果顯示個案資料主要為男性，平均年齡70.9歲。性別、心房顫動、心臟衰竭、末期腎病、鉀離子、白血球、IHCA前8小時的血氧濃度、以及IHCA前16和24小時的改良式早期預警評分是IHCA的預測因子。

結論：建議臨床上各醫院都應發展臨床早期警訊系統，內容包含生命徵象變化、檢驗數值的異常，亦可加入病人疾病特性進行評分，盡早發現與處理異常變化，降低嚴重不良事件發生。

Objective: To explore the predictors of in-hospital cardiac arrest(IHCA) in hospitalized patients.

Methods: A retrospective chart review of 230 general ward patients was conducted to compare individuals who experienced IHCA with those who did not. Data on demographics,diagnoses, laboratory results, and physiological parameters were analyzed using a ttest, chi-square test, and logistic regression.

Results: The results revealed that most patients were male, with an average age of 70.9 years. Predictors of IHCA comprised sex, atrial fibrillation, heart failure, end-stage renal disease, potassium level, white blood cell count, blood oxygen saturation within 8 hours before IHCA, and modified early warning scores at 16 and 24 hours prior to IHCA.

Conclusion: It is recommended that hospitals develop clinical early warning systems that incorporate changes in vital signs and abnormal laboratory values. These systems could also include patient-specific disease characteristics for scoring, enabling the early detection and management of abnormal changes, reducing the incidence of adverse events.
