Risk factors for 30‐day readmission in general medical patients admitted from the emergency department: a single centre study

摘要: Background:  Overcrowding in emergency departments (ED) around the world is an increasingly serious problem with adverse impact on both patient flow and outcomes. A significant contributing factor to ED overcrowding possibly due readmission. Risk factors for readmission patients admitted from are rarely studied, particularly Asian countries where length of stay reportedly longer. Methods:  retrospective study general medical wards a referral centre northern Taiwan November 2009 April 2010 was conducted. The primary outcome 30-day hospital clinical characteristics were analysed predictors readmission. Results:  Of recruited 2698 patients, 451 (16.7%) readmitted within 30 days after discharge. Age, gender, marital status activities daily living (Barthel's score) not associated Higher Charlson score ((score 2–4) hazard ratio (HR): 1.42, 95% confidence interval (CI): 1.07–1.89; (score >4) HR: 1.93, CI: 1.37–2.73), longer ((8–14 days) 1.51, 1.17–1.95; (15–28 days) 1.64, 1.22–2.19; (>28 days) 1.97, 1.43–2.71), presence underlying active malignancy (HR: 1.66, 1.27–2.16) anaemia 1.26, 1.02–1.55) independently readmission. Conclusion:  Medical have rate 16.7%. Post-discharge care should focus higher score, hospitalisation, malignancy, which independent predictive
