摘要:

目的构建胶囊内镜临床综合应用评价指标体系及确定各指标权重,并对国产与进口胶囊内镜进行评价,为胶囊内镜在临床综合应用包括技术、临床及市场性能的评价研究中提供科学依据。方法通过文献分析法及专家咨询法初步拟定评价指标体系框架,应用德尔菲(Delphi)法及层次分析法(analytic hierarchy process,AHP)确定胶囊内镜评价的一、二、三级指标及权重。采用因素分析法对国产与进口胶囊内镜进行评价指标的实证应用对比分析。结果两轮问卷的回收率分别为93.3%(28/30)、96.4%(27/28),专家平均权威系数分别为0.867、0.858,两轮咨询的一、二、三级指标肯德尔(Kendall)协调系数分别为0.324、0.189、0.140及0.280、0.192、0.124,经卡方检验均具有统计学意义(P<0.01),协调性一致。最终确定了胶囊内镜评价的一级指标3项、二级指标10项、三级指标41项以及各指标的权重,其中一级指标技术、临床及市场性能的权重分别为0.349 0、0.437 4、0.213 6。实证对比分析,技术性能指标国产胶囊内镜的尺寸显著小于进口胶囊内镜(P<0.01),胶囊质量显著大于进口胶囊内镜(P<0.01),分辨率显著低于进口胶囊内镜(P<0.05);临床性能指标国产胶囊内镜的图片处理时间显著长于进口胶囊内镜(P<0.01),图片清晰度显著低于进口胶囊内镜(P<0.01),记录仪携带的便携性及穿戴的舒适性显著优于进口胶囊内镜(P<0.01);市场性能指标国产胶囊内镜的价格显著低于进口胶囊内镜(P<0.01)。结论各级指标专家意见集中,协调程度好,结果可信度高,构建的胶囊内镜评价指标体系科学、合理、实用,为胶囊内镜的临床综合应用评价提供了客观、可量化的依据。
 

Abstract:

ObjectiveTo establish an index evaluation system for evaluating the comprehensive clinical applications of capsule endoscopy and determine the weight of each indicator, and then utilize the evaluation system to comparatively analyze the domestic and imported capsule endoscopy in order to provide scientific basis for the applications including technology, clinic and market performance of the capsule endoscopy eventually. MethodsThe framework of evaluation system was preliminarily formulated through literature analysis and expert consultation, and the 3-level indicators and weight of them in capsule endoscopic evaluation were determined by Delphi method and analytic hierarchy process (AHP). Factor analysis was employed to empirically analyze the evaluation indexes of domestic and imported capsule endoscopes. ResultsThe response rates of the 2 questionnaires were 93.3% (28/30) and 96.4% (27/28), respectively; the average authoritative coefficients of the experts were 0.867 and 0.858, respectively. The Kendall (Kendall) coordination coefficients of the 3-level indicators in the 2 questionnaires were 0.324, 0.189 and 0.140, and 0.280, 0.192 and 0.124, respectively (P<0.01, by Chi-square test), with certain consistency. At last, we determined 3 indicators of primary indexes, 10 indicators of secondary indexes, and 41 indicators of tertiary indexes, and the weights of each indicator, among which the weights of first-level indicator for technology, clinic and market performance were 0.349 0, 0.437 4 and 0.213 6, respectively. Analysis of technical indicators showed that the domestic capsule endoscope had significantly smaller size (P<0.01), obviously larger weight (P<0.01), but remarkably lower resolution (P<0.05) when compared with the imported one. In the evaluation of clinical performance indexes, the domestic capsule endoscope had significantly longer image processing time (P<0.01), obviously lower picture resolution (P<0.01), but markedly better portability and comfortableness of the recorder (P<0.01) than the imported one. In terms of market performance, the price of domestic capsule endoscope was distinctly lower than that of imported capsule endoscopy (P<0.01). ConclusionOur obtained 3-level indexes by experts are concentrated, consistent and credible. The capsule endoscopic evaluation index system constructed by Delphi and AHP is scientific, reasonable and practical. And the practical comparative analysis can further provide an objective and quantifiable basis for the research of clinical evaluations.
