The development and application of medical technologies reflect the medical quality and clinical capacity of a hospital. It is also an effective approach in upgrading medical service and core competitiveness among medical institutions. This study aimed to build a quantitative medical technology evaluation system through questionnaire survey within medical institutions to perform an assessment to medical technologies more objectively and accurately, and promote the management of medical quality technologies and ensure the medical safety of various operations among the hospitals.
A two-leveled quantitative medical technology evaluation system was built through a two-round questionnaire survey of chosen experts. The Delphi method was applied in identifying the structure of evaluation system and indicators. The judgment of the experts on the indicators was adopted in building the matrix so that the weight coefficient and maximum eigenvalue (λ max), consistency index (CI), and random consistency ratio (CR) could be obtained and collected. The results were verified through consistency tests, and the index weight coefficient of each indicator was conducted and calculated through analytical hierarchy process.
Twenty-six experts of different medical fields were involved in the questionnaire survey, 25 of whom successfully responded to the two-round research. Altogether, 4 primary indicators (safety, effectiveness, innovativeness, and benefits), as well as 13 secondary indicators, were included in the evaluation system. The matrix is built to conduct the λ max, CI, and CR of each expert in the survey, and the index weight coefficients of primary indicators were 0.33, 0.28, 0.27, and 0.12, respectively, and the index weight coefficients of secondary indicators were conducted and calculated accordingly.
As the two-round questionnaire survey of experts and statistical analysis were performed and credibility of the results was verified through consistency evaluation test, the study established a quantitative medical technology evaluation system model and assessment indicators within medical institutions based on the Delphi method and analytical hierarchy process. Moreover, further verifications, adjustments, and optimizations of the system and indicators will be performed in follow-up studies.
医疗技术的发展和应用反映了医院的医疗质量和临床能力,也是提高医疗服务水平和医疗机构核心竞争力的有效途径。本研究旨在通过医疗机构内的问卷调查建立一个定量的医学技术评价体系,对医学技术进行更客观、准确的评估,促进医疗质量技术管理,确保医院各项操作的医疗安全。
采用德尔菲法两轮专家问卷调查,构建两级定量医学技术评价体系。采用德尔菲法确定评价体系结构和指标,运用专家判断矩阵构建,得出权重系数和最大特征值(λ max)、一致性指标(CI)和随机一致性比(CR)并进行收集。通过一致性检验验证结果,采用层次分析法计算各指标权重系数。
共纳入 26 名不同医学领域的专家参与问卷调查,其中 25 名专家成功完成两轮研究。共纳入评价体系 4 个一级指标(安全性、有效性、创新性、效益)和 13 个二级指标。构建矩阵,对专家进行λ max、CI 和 CR 的调查,并计算一级指标的指标权重系数分别为 0.33、0.28、0.27 和 0.12,二级指标的指标权重系数也相应计算。
通过两轮专家问卷调查和统计分析,采用一致性评价检验验证结果的可信度,本研究基于德尔菲法和层次分析法建立了医疗机构内的定量医学技术评价体系模型和评价指标。后续研究将对系统和指标进行进一步验证、调整和优化。
