          Abstract

          Resumo mentalidade enxuta e a sustentabilidade aplicadas à construção possuem como objetivo, respectivamente, mitigar desperdícios produtivos e diminuir os impactos negativos do setor. Pesquisas recentes afirmam que a aplicação em conjunto dos dois conceitos pode gerar interações e sinergias. O presente trabalho tem o objetivo de identificar como a construção enxuta e a sustentabilidade se relacionam e descrever esse relacionamento por seus pontos sinérgicos, pelas interações negativas e por outros conhecimentos relevantes. Para isso, o método de revisão sistemática da literatura foi utilizado, e sua execução resultou na seleção de 59 artigos para análises bibliométricas e qualitativas. Os artigos foram agrupados e classificados em seis focos de estudo. Os resultados bibliométricos indicam que o tema ganhou importância nos últimos cinco anos, tendo os Estados Unidos e o Brasil como maiores contribuidores. Já a análise qualitativa indica que a relação entre as abordagens é sinérgica, principalmente no sentido da construção enxuta para a sustentabilidade, e que a relação pode se fortalecer pelo alinhamento de conceitos de valor e desperdício. Conclui-se que, apesar de já existirem casos de integração de práticas e ferramentas, ainda há necessidade de estudos para o aprofundamento no tema.

          Abstract Lean thinking and sustainability applied to construction are aimed, respectively, at mitigating waste and reducing the negative impacts of the sector. Recent studies claim that the joint application of the two concepts can generate interactions and synergies. This study aims to identify how lean construction and sustainability relate to each other, as well as to describe this relationship through its synergistic points, negative interactions and other relevant knowledge. For this purpose, the method of systematic literature review was adopted, resulting in the selection of 59 articles for bibliometric and qualitative analysis. The articles were grouped and classified into 6 study foci. The bibliometric results indicate that the theme has gained importance in the last five years, with the United States and Brazil as major contributors. The qualitative analysis indicates that the relationship between the approaches is synergic, mainly from lean construction to sustainability, and that the relationship can be strengthened by the alignment of the concepts of value and waste. The conclusion of the study is that, although there are already cases of integration of practices and tools, there is still need for studies to deepen the knowledge on the subject.

          Methodology in conducting a systematic review of systematic reviews of healthcare interventions

          Background Hundreds of studies of maternity care interventions have been published, too many for most people involved in providing maternity care to identify and consider when making decisions. It became apparent that systematic reviews of individual studies were required to appraise, summarise and bring together existing studies in a single place. However, decision makers are increasingly faced by a plethora of such reviews and these are likely to be of variable quality and scope, with more than one review of important topics. Systematic reviews (or overviews) of reviews are a logical and appropriate next step, allowing the findings of separate reviews to be compared and contrasted, providing clinical decision makers with the evidence they need. Methods The methods used to identify and appraise published and unpublished reviews systematically, drawing on our experiences and good practice in the conduct and reporting of systematic reviews are described. The process of identifying and appraising all published reviews allows researchers to describe the quality of this evidence base, summarise and compare the review's conclusions and discuss the strength of these conclusions. Results Methodological challenges and possible solutions are described within the context of (i) sources, (ii) study selection, (iii) quality assessment (i.e. the extent of searching undertaken for the reviews, description of study selection and inclusion criteria, comparability of included studies, assessment of publication bias and assessment of heterogeneity), (iv) presentation of results, and (v) implications for practice and research. Conclusion Conducting a systematic review of reviews highlights the usefulness of bringing together a summary of reviews in one place, where there is more than one review on an important topic. The methods described here should help clinicians to review and appraise published reviews systematically, and aid evidence-based clinical decision-making.
