RESUMO Objetivo: identificar os instrumentos que são utilizados para avaliar o risco de lesão por pressão em pacientes críticos adultos de unidade de terapia intensiva e analisar a capacidade preditiva dos mesmos. Método: revisão integrativa observando-se os critérios para seleção dos estudos: avaliação do risco de lesão por pressão em pacientes internados em unidade de terapia intensiva de adultos por meio de escala ou índice; mensuração da capacidade preditiva do instrumento aplicado; idiomas inglês, português ou espanhol; período entre 1962 e 2016. Os descritores utilizados foram: pressure ulcer ou pressure sores e risk assessment. As variáveis de interesse foram: sensibilidade, especificidade, valor preditivo positivo, valor preditivo negativo e área sob a curva receiver operator characteristic. Resultados: : foram identificadas 1032 publicações e deste total foram selecionados 13 estudos para análise. A predição do risco para lesão por pressão foi mensurada unicamente com escalas genéricas em sete dos 13 estudos. Nos estudos comparativos de escalas específicas de unidade de terapia intensiva com escalas genéricas, o valor preditivo negativo foi elevado e todos com área da curva receiver operator characteristic com valores acima de 0,700. Entre as escalas genéricas predominou a escala de Braden. Foram identificadas seis escalas que apresentaram boa capacidade preditiva para avaliar risco de lesão por pressão em pacientes de unidade de terapia intensiva. Conclusão: : esta revisão revelou uma variedade de escalas preditivas, genéricas e específicas, que são utilizadas para avaliação de risco de lesão por pressão no paciente de unidade de terapia intensiva.
Objective: to analyze the scientific production on the results of Lean Six Sigma methodology in health care institutions. Methods: an integrative literature review, with the following question: what are the results in health institutions using Lean Six Sigma and Six Sigma methodology? The search was carried out at MEDLINE, LILACS, BDENF, CINAHL, Web of Science, and Scopus, with no time frame. Results: thirty-four articles were included, published between 2005 and 2019, of which 52.9% came from the United States of America. The most commonly found improvements were in hospital institutions and from the perspective of customers and internal processes. Conclusion: using Lean Six Sigma methodology proved to be effective in the different health care settings, evidencing a gap in its application regarding people engagement and training.
Objectives: to describe the Lean Six Sigma implementation process to improve the discharge process in a Brazilian health institution’s ICU. Methods: prospective study following the Define-Measure-Analyse-Improve-Control project development method. This method consists of five phases, namely: project definition, measurement of the starting point and data collection, analysis of results, improvement in processes, and statistical control. Results: applying Lean Six Sigma methodology following the Define-Measure-Analyse-Improve-Control in the discharge process from the intensive care unit to the inpatient unit was effective in improving processes. This improvement represented a reduction in the mean patient transfer time to the inpatient unit from 189 minutes to 75 minutes, representing a 61% improvement in discharge time. Conclusions: this article demonstrates the effectiveness of applying Lean Six Sigma methodology to improve the discharge flow in a critical unit, resulting in time and waste reduction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
