Abstract
Stroke is the second leading cause of death worldwide with an annual mortality rate of 6.55 million, which accounts for 11.6% of the total number of deaths. Early diagnosis is crucial for improving treatment outcomes. Lean management is an approach originating in the car manufacturing process derived from the Toyota Production System, which healthcare providers have recently adapted. The objective is to examine the use of lean practices in managing AIS in hospital settings. A systematic literature search was performed using MEDLINE and SCOPUS databases, including publications from 1st January 2000 to 20th September 2022. A total of 13 studies fulfilled the predefined inclusion criteria. The recombinant tissue plasminogen activator (rtPA) was used in 11 studies, in 2 studies in combination with mechanical thrombectomy (MT). MT alone was used in the other 2 studies. The value stream mapping was used in all included studies to analyze workflow in acute ischemic stroke (AIS) treatment. Outcome measures include mostly door-to-needle (DTN) time for rtPA treatment and door-to-puncture (DTP) time for mechanical thrombectomy. DTN time was assessed in nine studies and reached statistically significant results in five. DTP was examined in three studies; in two, statistically significant decreases in DTP were observed. Lean management can be a useful method for achieving key performance indicators in AIS, consistent with current guidelines. The results of this systematic literature review show that value stream mapping may improve the process of AIS treatment by reducing in-hospital delays. The field of research that focuses on implementing lean management tools in healthcare is increasing, with more publications appearing in recent years.
