共享单车已经成为实现绿色出行的重要途径,研究以共享单车的服务质量作为切入点进行理论与实证研究,通过理论梳理导出了对共享单车服务质量具有针对性的评价指标,并构建了其与感知价值、满意度和行为意图的理论模型,通过对北京、济南和杭州3个城市的调查,收集了304份有效样本,通过实证检验发现:1)可达性、信赖性、便利性、经济性(直接和间接经济性)和连通性5个属性是构成共享单车服务质量的重要评价因素;2)可达性、便利性、经济性和连通性4个指标对感知价值均存在显著影响;3)可达性、信赖性、便利性、经济性和连通性5个属性对满意度均存在显著影响;4)可达性、信赖性、便利性、经济性和连通性5个属性对行为意图均存在显著影响;5)感知价值对满意度和行为意图均存在显著影响;6),满意度对行为意图存在显著影响.

Objective:To discuss the feasibility of using online and offline combined multidisciplinary team (MDT) diagnosis-treatment mode in cancers diagnosis and treatment by comparing the comprehensive diagnosis and treatment plans formulated by online and offline MDT diagnosis-treatment mode.Methods:A total of 168 esophageal cancer patients collected from March 17, 2020 to May 17, 2020 were took as the research objects in Shandong Cancer Hospital and Institute, through whom the consistency of the comprehensive diagnosis and treatment plans formulated by online and offline MDT diagnosis-treatment mode was evaluated. The clinical characteristics of patients with changed comprehensive diagnosis and treatment plans, such as age, Karnofsky performance status (KPS) score, whether combined with basic diseases, whether received anti-tumor treatment before and tumor location were analyzed, so as to explore the mechanism to improve the efficiency on the basis of quality assurance.Results:The results showed that 86.3% (145/168) of the comprehensive diagnosis and treatment plans obtained by offline MDT diagnosis-treatment mode were consistent with online diagnosis-treatment MDT mode. Cases with inconsistent comprehensive diagnosis and treatment plans were characterized by elderly (> 69 years) ( χ2=4.250, P=0.039), KPS score≥80 ( χ2=15.520, P<0.001) and combined with underlying disease ( χ2=7.135, P=0.008). Through further analysis, the changed cases were also characterized as with inadequate auxiliary examination or complex in imaging. Conclusion:The online and offline combined MDT diagnosis-treatment mode is feasible. For the patients characterized of elderly (> 69 years old), KPS score ≥80, combined with underlying diseases, with incomplete auxiliary examination or complex in imaging, the offline MDT diagnosis-treatment mode should be adopted or supplemented.
