Healthcare services are facing challenges in increasing their efficiency, quality of care, and coping with surges in demand. To this end, some hospitals have implemented lean healthcare. The aim of this systematic review is to evaluate the effects of lean healthcare (LH) interventions on inpatient care and determine whether patient flow and efficiency outcomes improve. The review was performed according to PRISMA. We used six databases to search for studies published from 2002 to 2019. Out of 5732 studies, 39 measuring one or more defined outcomes were included. Hospital length of stay (LOS) was measured in 23 studies, 16 of which reported a reduction, turnover time (TOT) decreased in six out of eight studies, while the turnaround time (TAT) and on-time starts (OTS) improved in all five and seven studies, respectively. Moreover, eight out of nine studies reported an earlier discharge time, and the boarding time decreased in all four cases. Meanwhile, the readmission rate did not increase in all nine studies. Lastly, staff and patient satisfaction improved in all eight studies. Our findings show that by focusing on reducing non-value-added activities, LH contributed to improving patient flow and efficiency within inpatient care.

评估精益医疗对住院护理的影响：系统评价。

医疗保健服务在提高效率，护理质量以及应对需求激增方面面临挑战。为此，一些医院已经实施了精益医疗。该系统评价的目的是评估精益医疗保健（LH）干预措施对住院护理的影响，并确定患者流量和效率结果是否得到改善。审查是根据PRISMA进行的。我们使用六个数据库搜索了2002年至2019年发布的研究。在5732项研究中，有39项测量了一项或多项明确的结果。在23项研究中测量了住院时间（LOS），其中16项报告减少了住院时间，八项研究中的六项报告了周转时间（TOT）减少了，而在18项研究中，周转时间（TAT）和准时开始时间（OTS）有所改善所有五个和七个研究分别。此外，9项研究中有8项报告出院时间较早，而这4例病例的登机时间均减少了。同时，所有九项研究的再入院率均未增加。最后，在所有八项研究中，员工和患者的满意度都有所提高。我们的研究结果表明，通过专注于减少非增值活动，LH有助于改善住院治疗中的患者流量和效率。
