Resumo

JUSTIFICATIVA E OBJETIVOS: As revisões sistemáticas organizam dados da literatura, combinando os resultados dos estudos publicados com o objetivo de resolver conflitos na área do conhecimento médico descrevendo as intervenções. O relato inadequado das revisões sistemáticas pode prejudicar sua credibilidade e interferir na qualidade de seus resultados. O objetivo deste estudo foi determinar a frequência de revisões sistemáticas de boa qualidade que comparam a anestesia neuroaxial com a anestesia geral para procedimentos na metade inferior do corpo. MÉTODO: Revisão sistemática de revisões sistemáticas, com variável primária sendo a frequência de revisões sistemáticas de boa qualidade. As informações foram analisadas a partir dos seguintes bancos de dados: LILACS (janeiro de 1982 a dezembro de 2010), PubMed (janeiro de 1950 a dezembro de 2010), Cochrane Database of Systematic Review e Database of Abstracts of Reviews of Effects (volume 10, 2010), e SciELO (em dezembro de 2010). A qualidade das revisões sistemáticas foi determinada pelo Overview Quality Assessment Questionnaire. O cálculo do tamanho da amostra demonstrou ser necessária a análise de 8 revisões sistemáticas, considerando que a frequência de revisões sistemáticas de boa qualidade foi de 5%, a precisão absoluta de 15% e o nível de significância de 5%. RESULTADOS: Foram identificados 1.995 artigos. O processo de seleção eliminou 1.968 artigos. Foram lidos 27 artigos de revisões sistemáticas na íntegra, foram excluídos 9 devido à incompatibilidade com os critérios de inclusão, e 8 eram publicações duplicadas. Dez revisões sistemáticas foram analisadas quanto a sua qualidade. A frequência de revisões sistemáticas de boa qualidade foi de 40% (4/10; IC 95% 9,6 a 70,4%). CONCLUSÃO: A frequência de revisões sistemáticas de boa qualidade foi de 40%.

Abstract

BACKGROUND AND OBJECTIVES: Systematic reviews organize literature data by combining results from published studies in order to resolve conflicts in the area of medical knowledge describing the interventions. The inadequate reporting of systematic reviews can damage the credibility and interfere in the results' quality. The objective of this study was to determine the frequency of good quality systematic reviews comparing neuraxial anesthesia with general anesthesia for procedures on the lower half of the body. METHODS: Systematic review of systematic reviews. Primary variable: The frequency of good quality systematic reviews. The information was analyzed from the following databases: LILACS (January 1982 to December 2010); PubMed (January 1950 to December 2010); The Cochrane Database of Systematic Review and Database of Abstracts of Reviews of Effects (volume 10, 2010); and SciELO (December 2010). The quality of systematic reviews was determined by the Overview Quality Assessment Questionnaire. The sample size calculation showed that it was necessary to analyze eight systematic reviews, taking into account that the frequency of good quality systematic reviews was 5%, an absolute precision of 15%, and a significance level of 5%. RESULTS: Were identified 1,995 articles. The selection process eliminated 1,968 articles. Twenty-seven articles of systematic reviews were read in full, 9 were excluded due to incompatibility with the inclusion criteria, and 8 were duplicate publications. Ten systematic reviews were assessed for their quality. The frequency of good quality systematic reviews was 40% (4/10; 95% CI 9.6 to 70.4%). CONCLUSION: The frequency of good quality systematic reviews was 40%.
