Saving time means saving neurons in stroke care process. Managerial and organizational solutions that lean the processes should be considered in order to overcome the effects of stroke, which is the second worldwide cause of death. The purpose of the paper is to understand how Health Lean Management (HLM) can be adopted to achieve a more efficient stroke care process. In this peculiar context, efficiency enhancement leads to safety and effectiveness results. For this reason, the investigated projects have been recognized as Lean & Safety (L&S) projects, being HLM projects reporting patient safety improvements. Due to the peculiarity of the project to investigate, a holistic case study has been conducted in a university hospital of Tuscany region. Thanks to the research framework developed in the literature for L&S projects, data regarding motivations, objectives, organizational and managerial aspects, outcomes, enablers and obstacles of the project have been collected and analysed. A multidisciplinary team, already trained on HLM and supported by the top management, was created and the step-by-step Six Sigma approach was adopted. After a mapping phase, a value stream map was created, Key Performance Indicators were defined and, finally, the Door To Needle (DTN) times and the modified Rankin Scales (mRS) were measured. Thanks to root cause analysis, the identified wastes were analyzed and intervention actions were defined and implemented. They regarded mainly different organizational interventions and they led to a decrease of both DTN times and mRS. The analysed project has demonstrated how it is possible to obtain relevant operational and clinical outcomes through organizational solutions. The analysis of this project, in which pursuing efficiency has led to safety and effectiveness results, has demonstrated how these different performances are linked each other in some peculiar care processes, in which shorter time means more effective and safer care, as in the stroke case. The implementation of L&S projects can improve care processes, providing a contribution to realize a more efficient, effective and safer healthcare system.
