長期照護機構中的老人再次住院的相關因素探討

The Factors Associated with Hospital Readmissions of Elderly Residents in Long-term Care Facilities

本研究目的為探討長期照護機構老人出院後14天內再住院之相關因子。研究方法利用病歷資料進行回溯性分析，從中南部某區域教學醫院65歲以上老人為研究對象，排除重覆住院兩次以上者，有效個案總計191位。以多因子羅吉斯迴歸分析。結果顯示14天內再住院顯著因子為血糖大於200 mg/dl者（勝算比4.7，p <.001）、住院時尿素氮值異常者 （勝算比2.5，p =.031）、出院時白血球數異常者 （勝算比3.2，p =.019）。建議未來在出院準備計畫過程中，參考以上檢驗因子，藉此降低再住院率。

The present study aimed to investigate the factors associated with hospital readmissions of the elderly residing in long-term care (LTC) facilities. A retrospective analysis of the medical records of LTC residents aged 65 years and above who were admitted to the geriatric ward of a regional teaching hospital in Southern Taiwan was carried out. After excluding patients with repeated readmissions, 191 patients were included in the analysis using logistic regression. Results showed that 14-day hospital readmission was associated with blood glucose greater than 200 mg/dl at admission (odds ratio=4.7, p <.001), abnormally high values of blood urea nitrogen (BUN) level at admission (odds ratio=2.5, p =.031), and high white blood cell count at discharge from the hospital (odds ratio =3.2, p =.019). These factors may be used in assisting hospital discharge planning to prevent the occurrence of readmission.
