胸腔闭式引流系统效能评价指标体系的构建研究

Research in effectiveness evaluation indicator for thoracic close drainage system

目的建立一套科学、客观、实用的胸腔闭式引流系统效能评价指标。方法通过查阅胸腔闭式引流系统循证临床实践及相关文献，初步拟定评价指标，采用德尔菲（Delphi）法对23名专家进行2轮专家咨询确立指标体系。结果第1轮专家的积极性系数为92％，第2轮专家的积极性系数为100％；确立了包含3个维度，12个指标，50个评价依据的效能评价指标体系；专家权威系数为0．987。结论该评价体系具有较好的可靠性和权威性，临床医务人员可据此对胸腔闭式引流系统的引流效能做出评价。

Objective To establish a scientific, objective and practical evaluation scale for thoracic close drainage system. Methods Based on the evidence-based practice and related documents, the indicators of efficiency for thoracic close drainage system were identified tentatively. Then Delphi method was used and 23 experts were investigated and consulted by two rounds. Results The index of experts activity was 92% and 100% in the first and second round of Delphi consultation, respectively. The scale comprised 50 indicators in 3 dimensions, the experts＇ authority coefficient was 0.987. Conclusions The reliability and authority of the scale are acceptable and it can be used to evaluate the efficiency of thoracic close drainage system.
