Several health services have used lean healthcare to seek continuous improvement of their processes. Therefore, it is important to investigate the evidence available in the literature about the most used lean tools in the health area to review processes and the main results achieved by the researchers. As an integrative literature review methodology was used, it was conducted in five databases, using the descriptor “quality improvement” and the keyword “Lean Healthcare”. A total of 33 complete articles were selected for analysis. The most recurrent tools were: define, measure, analyze, improve and control (DMAIC); value stream map (VSM); suppliers, inputs, process, outputs, customers analysis (SIPOC), Ishikawa Diagram and 5S. Through the analysis of waste, different interventions were implemented and the main results achieved were reduction in times (processing, waiting, cycle and total), costs, workload and increase in the number of calls. The findings enabled the identification of the main lean tools used in the health area to achieve better results. In particular, we highlight recent studies that have explored the lean six sigma healthcare approach. The results, in addition to contributing to the literature, will also assist managers in choosing the best tool to achieve continuous improvement in hospitals and other health services.

Objective: to measure the level of structural empowerment of nurses working in a university hospital. Method: a descriptive, analytical, and cross-sectional study, carried out with 237 nurses, who developed care and management activities. Data collection took place through a self-administered questionnaire with questions on the personal and professional characterization and the Work Effectiveness Conditions Questionnaire II. Data analysis used descriptive and inferential statistics. Results: it was identified that nurses have a moderate level of structural empowerment (18.06±SD 0.9). The greatest value was obtained in the Opportunity dimension (4.08±SD 0.8), followed by the Resources (3.17±SD 0.8) and Informal power (3,04±SD 0.9) dimensions; while the scores of Support (2.67±SD 1.0), Formal power (2.59±SD 0.9), and Information (2.51±SD 0.9) were lower. Conclusion: the level of structural empowerment of the nurses was moderate, which means partial access to opportunities, resources, support, and information of the institution.
