JAMDA:觉醒障碍的老人会导致住院时长增加并转入SNF

2015-07-15 MedSci MedSci原创

背景:认知功能障碍与老人居住环境不佳有关,但是用于完成此临床研究的检测指标是很难选择的。本研究旨在研究觉醒障碍(使用简单的屏幕测试)与两种临床结果的风险:住院时间延长和去专业养老机构(SNF)。 方式:该研究将研究数据进行二次分析,研究数据来源于两个独立组:美国东北部一个退伍军人医疗中心2010-2012年就诊的、年龄超过60岁的1487位病人(称为1组);另外一组是美国东南部一家大型三

背景:认知功能障碍与老人居住环境不佳有关,但是用于完成此临床研究的检测指标是很难选择的。本研究旨在研究觉醒障碍(使用简单的屏幕测试)与两种临床结果的风险:住院时间延长和去专业养老机构(SNF)。

方式:该研究将研究数据进行二次分析,研究数据来源于两个独立组:美国东北部一个退伍军人医疗中心2010-2012年就诊的、年龄超过60岁的1487位病人(称为1组);另外一组是美国东南部一家大型三级医疗保健大学附属医院就诊的、年龄超过65岁的669位病人(称为2组)。觉醒困难被里士满躁动/镇静量表(the Richmond Agitation Sedation Scale,RASS)定义为“不同于清醒和警觉状态的其他状态”。我们使用Cox比例风险回归模型确定老人出院的时间,并使用逻辑回归分析确定老人去SNF的时间。同时也记录了与之相应的风险比(HRs)和优势比(OR)及95%的可信区间。我们对样本的年龄、性别、痴呆程度都有所控制和调整。

结果:2156名受调查患者的平均年龄为76岁,在1组和2组中存在觉醒障碍的患者的占比分别是16.4%和28.5%。在第一组,正常觉醒的患者平均住院时间为5.9天(标准差为6.2),而觉醒障碍的患者则为8.5天(标准差为9.2);在住院的任何一天,觉醒正常的老人相比觉醒障碍的患者,出院的几率降低27%(调整后的风险比为0.73,95%可信区间为0.63 - 0.84)。在2组,正常觉醒的患者平均住院时长为3.8(标准差为4.1)天,觉醒障碍的患者住院时长则为4.7(标准差为4.6)天;在住院的任何一天,觉醒正常的老人相比觉醒障碍的患者,出院的几率降低21%(调整后的风险比为0.79,95%可信区间为0.66 - 0.95)。论及出院转至SNF的老人,在1组,觉醒障碍的患者入住SNF的几率要比觉醒正常的患者高65%(调整后的风险比为1.65,95%可信区间为1.21 - 2.25);2组觉醒障碍的患者入住SNF的几率要比觉醒正常的患者高27%(调整后的风险比为1.27,95%可信区间为0.80 - 2.03)。但是该研究并未控制老人并发症这一变量,因此这是一个明显的不足。

结论:这一研究调查了超过2000名住院患者,该研究表明,患者是否有觉醒障碍及其程度可能是导致患者住院时间延长及出院转入SNF的高危因素。
