Construction and value research of quantitative and qualitative joint evaluation model in ventilator quality control management

目的:构建定量定性联合质量评估模型,探讨其在呼吸机质量控制管理中的应用价值。方法:质量评估模型由指标集和评估集两部分构成,运用层次分析(AHP)法进行定性评估权重赋值。选取医院临床在用的57台呼吸机,根据管理模式不同分为对照组(52台)和观察组(55台,包含对照组50台和新增5台),对照组采用定性定量分阶段评估模式;观察组采用定量定性联合质量评估模式,从结构外观、待机运行、技术参数、安全性能和报警功能5个维度制定19项质量指标集开展质量控制管理。对比两组的设备运行质量及相关人员管理水平。结果:观察组呼吸机结构外观、待机运行、安全性能、报警功能的4项定性评估分数高于对照组,差异有统计学意义(t=2.950,t=4.227,t=2.465,t=2.660;P<0.05);观察组呼吸机氧浓度、潮气量、呼吸频率、吸气流速、吸气触发灵敏度、呼气触发灵敏度、吸气压力和呼气末正压的8项定量评估分数高于对照组,差异有统计学意义(t=2.421,t=4.112,t=2.821,t=2.929,t=3.762,t=4.538,t=3.318,t=3.622;P<0.05);观察组呼吸机相关使用人员专业理论知识、操作和(或)维修技能及行业标准规范考核成绩好于对照组,差异有统计学意义(t=4.307,t=5.647,t=4.178;P<0.05)。结论:定量定性联合质量评估模型能够提高呼吸机临床运行质量,降低设备安全风险,提升设备质量检测合格比例和设备相关人员使用操作及技术保障能力。

Objective: To construct a quantitative and qualitative joint evaluation model and explore its application value in ventilator quality control. Methods: The ventilators in clinical use in the hospital were selected and divided into the control group(52 units) and the observation group(55 units) according to different management modes. The control group adopted a qualitative and quantitative staged assessment model. The observation group adopted the quantitative and qualitative joint evaluation model, 19 quality index sets from 5 dimensions were established and quality control management was carried out through the quantitative and qualitative joint evaluation model. The equipment operation quality and management level of related personnel were compared between the two groups. Results: The qualitative evaluation scores of ventilator structure appearance, standby operation, safety performance and alarm function in the observation group were higher than those in the control group, the difference was statistically significant(t=2.950, t=4.227, t=2.465, t=2.660, P<0.05);the quantitative evaluation scores of ventilator oxygen concentration, tidal volume, respiratory rate, inspiratory flow rate, inspiratory trigger sensitivity, expiratory trigger sensitivity, inspiratory pressure and positive end-expiratory pressure in the observation group were higher than those in the control group, the difference was statistically significant(t=2.421, t=4.112, t=2.821, t=2.929,t=3.762, t=4.538, t=3.318, t=3.622, P<0.05);the evaluation scores of professional theoretical knowledge, operation and(or)maintenance skills and industry standards and codes of ventilators related personnel in the observation group were better than those in the control group, the difference was statistically significant(t=4.307, t=5.647, t=4.178, P<0.05). Conclusion:The quantitative and qualitative joint evaluation model can improve the quality of clinical operation of ventilators, reduce safety risks of equipment, improve the qualified proportion of equipment quality inspection and the ability of equipmentrelated personnel in use operation and technical support.
