A catheterization laboratory (Cath lab) is a place that has high-tech equipment that mainly allows the diagnosis and treatment of cardiovascular diseases which represents a 31% of all global deaths according to the World Health Organization. (WHO, 2019) In an attempt to minimize process inefficiencies in Cath Lab, these organizations have been using quality improvement project such as Six Sigma, Lean Six Sigma, Kaizen events (rapid improvement events), general quality improvement projects (plan-do-check-act) and others. However, there is a lack of publications synthetizing the literature available in this research field (quality improvement project). Therefore, the aim of this paper is to assess the published literature relating quality improvements projects in Cath labs in three dimensions: publication characteristics, author characteristics and content characteristics. In order to achieve the purpose of this research, a systematic literature review (SLR) will be conducted to obtain the most relevant papers from three platforms: EBSCOhost, ProQuest and Scopus
