Liver cancer is one of the malignant tumors worldwide, while the prevention and control situation is grim at present, and the diffusion of its early screening technology still faces some challenges. This study aims to investigate the influencing mechanism of perceived ease of use, organizational support mechanism, and industry competitive pressure on hepatic early screening technologies use by physicians, so as to promote the wider use of corresponding technologies.
Under the theoretical guidance of technology-organization-environment framework and mindsponge theory, this study took hepatic contrast-enhanced ultrasound as an example, and conducted a cross-sectional questionnaire by randomly selecting physicians from Fujian and Jiangxi provinces in China with a high and low incidence of liver cancer, respectively. Structural equation modeling was used to determine the correlation among perceived ease of use, organizational support mechanism, and industry competitive pressure, as well as their impact on the physicians' behavior toward contrast-enhanced ultrasound use.
The hypothesis model fits well with the data (/df = 1.863, GFI = 0.937, AGFI = 0.908, RMSEA = 0.054, NFI = 0.959, IFI = 0.980, CFI = 0.980). Under technology-organization-environment framework, the perceived ease of use ( = 0.171, < 0.05), organizational support mechanism ( = 0.423, < 0.01), industry competitive pressure ( = 0.159, < 0.05) significantly influenced physicians' use of hepatic contrast-enhanced ultrasound. Besides, perceived ease of use and organizational support mechanism ( = 0.216, < 0.01), perceived ease of use and industry competitive pressure ( = 0.671, p < 0.01), organizational support mechanism and industry competitive pressure ( = 0.330, < 0.01) were all associated significantly.
From the lens of information processing (mindsponge theory) and technology-organization-environment framework, this study clarified the social and psychological influencing mechanism of perceived ease of use, organizational support mechanism, and industry competitive pressure on physicians' use of hepatic contrast-enhanced ultrasound. The results will directly propose recommendations for expanding hepatic contrast-enhanced ultrasound utilization and indirectly promoting other appropriate and effective health technologies diffusion within the integrated health system.
肝癌是全球范围内的恶性肿瘤之一，目前其防控形势严峻，早期筛查技术的推广应用仍面临诸多挑战。本研究旨在探讨医师对肝脏早期筛查技术采用意愿的感知易用性、组织支持机制和行业竞争压力的影响机制，以促进相应技术的广泛应用。
本研究以肝脏超声造影技术为例，基于技术-组织-环境框架和信息海绵理论，采用横断面问卷调查法，随机抽取我国肝癌高发和低发省份（福建、江西）的医师进行调查。采用结构方程模型分析感知易用性、组织支持机制和行业竞争压力与医师采用超声造影技术行为之间的相关性及其影响。
假设模型与数据拟合良好（/df=1.863，GFI=0.937，AGFI=0.908，RMSEA=0.054，NFI=0.959，IFI=0.980，CFI=0.980）。在技术-组织-环境框架下，感知易用性（β=0.171，p<0.05）、组织支持机制（β=0.423，p<0.01）、行业竞争压力（β=0.159，p<0.05）对医师采用肝脏超声造影技术具有显著影响。此外，感知易用性和组织支持机制（β=0.216，p<0.01）、感知易用性和行业竞争压力（β=0.671，p<0.01）、组织支持机制和行业竞争压力（β=0.330，p<0.01）之间存在显著的正向关联。
本研究从信息加工视角（信息海绵理论）和技术-组织-环境框架出发，揭示了感知易用性、组织支持机制和行业竞争压力对医师采用肝脏超声造影技术的社会心理影响机制，为扩大肝脏超声造影技术的应用提供了直接建议，并为整合卫生系统内其他适宜有效卫生技术的推广应用提供了间接建议。
