病人短時間內反覆住院,不僅加重醫療成本的支出,也影響病患完善醫療的照顧與權益,更增加家屬的心理及經濟負擔。雖有少數非計畫性再住院是無法避免的,但仍應努力減少。本研究以南部某區域教學醫院胃腸肝膽科住院病患為對象,收集2011年至2013年期間再入院病人之各項社會人口學及臨床特徵和住院處置與出院後照顧資料,含性別、年齡、社會季節、飲食習性、高血壓、消化系統及其他疾病、住院和出院計畫、出院準備、後續衛教、居家護理、家屬支持照顧等,以決策樹及邏輯斯回歸之分類技術,建立胃腸肝膽科出院後14天再入院之預測模式,期有效的減少再住院率,提高醫療品質。 Repeated admissions of patients in a very short period of time not only increase the medical costs and expenses, but also has a great impact on the quality of medical service and family’s burden. Except for a very few exception, unscheduled admissions should be avoided whenever possible specifically of those re-admissions that are within 14 days after the last discharge. With information collected during the admissions at the department of gastroenterology of a regional hospital in south Taiwan from 2011 to 2013, this study aims to test predictive models hypothesized for their re-admissions against various socio-demographic, clinical and other supportive factors using multiple logistic regressions.
