简介：目的:探讨分析5S管理对消化科手术室优质护理服务的促进作用。方法:选取2017.03-2018.03在我院进行5S管理的60例消化科手术室工作记录作为研究组,同期未进行5S管理的60例消化科手术室工作记录作为对照组,对比其护理情况。结果:研究组术间、术后物品归位摆放程度,患者衣物及时归还率以及护士综合素质合格率显著高于对照组,手术准备时间显著低于对照组,两组间差异性显著,P<0.05,有统计学意义,对照组患者术后不良反应发生率也低于对照组,P<0.05,有统计学意义。结论:在消化科手术室优质护理服务中采用5S管理可提高护士的自主护理意识,降低消化科患者的不良反应发生率,有利于优质护理服务的顺利进行。
