General characteristics of the participants.

BackgroundHospital readmission after discharge for stroke is associated with high morbidity and mortality. There is a paucity of data on the burden of stroke readmission in most sub-Saharan African countries. We aimed to determine the rate, reasons and predictors of hospital readmission and the mortality rate within 12 months of discharge among stroke survivors in Cameroon.MethodsThis prospective cohort included patients who survived hospitalization for an acute stroke and who were discharged from two referral hospitals in the capital city of Cameroon between January 2013 and December 2013.We performed logistic regression analysis to identify demographic and clinical factors associated with readmission within 1 year of discharge and causes of readmission.ResultsOf the 254 consecutive patients admitted for acute stroke, 198 were discharged alive. There were 107 (54%) males, and their mean age (SD) was 61.7 (13.9) years (range: 10 to 95 years). A total of 30 (15.2%) patients were readmitted following discharge from the index admission over a mean follow-up time of 286.9 (127.6) days. Of these, 14 (46.7%) were discharged and 16 (53.3%) died after readmission. Thirty percent (30%) of readmissions occurred within the first month. The most frequent causes of readmissions were infections (30%) and recurrent stroke (26.7%). Factors associated with readmission in bivariate analysis were initial admission temperature > 37.5°C (risk ratio [RR]: 1.3, p = 0.021) and initial admission Glasgow Coma Score 37.5°C (adjusted RR: 1.3, 95% CI: 1–1.7, p = 0.036) and GCS ConclusionReadmission after discharge for stroke was common with nearly one third occurring within the first month and more than half dying following readmission. The most common causes of readmission were infections and recurrent stroke.【背景】卒中（stroke）患者出院后的医院再入院与较高的发病率和死亡率密切相关。目前多数撒哈拉以南非洲国家关于卒中再入院负担的相关数据仍较为匮乏。本研究旨在明确喀麦隆卒中幸存者出院后12个月内的医院再入院率、再入院原因及预测因素，并分析该群体同期的死亡率。【方法】本前瞻性队列研究纳入了2013年1月至2013年12月期间，在喀麦隆首都两家转诊医院接受急性卒中住院治疗并存活出院的患者。我们采用logistic回归分析，以识别出院后1年内再入院相关的人口学与临床因素，以及再入院的具体原因。【结果】本研究共纳入254例因急性卒中住院的连续患者，其中198例存活出院。受试者中男性107例（54%），平均年龄（标准差）为61.7（13.9）岁（年龄范围：10~95岁）。在平均随访286.9（127.6）天期间，共有30例（15.2%）患者在首次住院出院后发生再入院。其中14例（46.7%）再次出院，16例（53.3%）在再入院后死亡。30%的再入院事件发生于出院后1个月内。再入院最常见的诱因为感染（30%）与复发性卒中（26.7%）。双变量分析显示，与再入院相关的因素包括入院时体温＞37.5℃（风险比[RR]：1.3，p=0.021）以及入院时格拉斯哥昏迷评分（Glasgow Coma Score, GCS）相关指标（原文此处疑似存在笔误，重复提及体温指标）；校正后的分析显示，入院时体温＞37.5℃（校正后RR：1.3，95%置信区间[CI]：1~1.7，p=0.036）与再入院显著相关。【结论】卒中患者出院后再入院的情况较为常见，近三分之一的再入院事件发生于出院后1个月内，且超过半数患者在再入院后死亡。再入院最常见的诱因为感染与复发性卒中。
