BACKGROUND

Unbalanced distribution of medical resources is becoming a major challenge, particularly in the selection of doctors. e-Consultation could provide patients with more choices of doctors and break the constraints of time and space. However, the acceptance of e-consultation is still poor and the mechanism of adoption is unclear.

OBJECTIVE

The aim of this study was to identify the factors influencing the public intention to use e-consultation and explore the effect path of the factors and behavior intention.

METHODS

The hypotheses of our research model were developed based on the technology acceptance model and perceived risk theory. A web-based survey was conducted by an electronic questionnaire collection platform; this survey that consisted of a 29-item questionnaire with 5-point Likert scales was completed by 934 respondents. Structural equation modeling was used to analyze the data. Item evaluation and reliability, validity, path loading, goodness of fit, and multiple group analysis were used to check the moderation effects.

RESULTS

The standardized factor loadings of the items were between 0.551 and 0.873. The composite reliability of 9 constructs ranged from 0.706 to 0.840. The average variance extracted ranged from 0.387 to 0.640. The fitness indices showed that the collected data fitted well with the research model. Perceived usefulness was the strongest positive factor effecting behavior intention (β=.399, <i>P</i>&lt;.001). Perceived ease of use had a positive effect on behavior intention but it was not statistically significant (β=.117, <i>P</i>=.07) and it had a positive effect on perceived usefulness (β=.537, <i>P</i>&lt;.001). Perceived risk could be well explained by financial risk (β=.972, <i>P</i>&lt;.001), privacy risk (β=.774, <i>P</i>&lt;.001), social risk (β=.871, <i>P</i>&lt;.001), time risk (β=.894, <i>P</i>&lt;0.001), and psychological risk (β=.774, <i>P</i>&lt;.001). Perceived risk had negative effects on perceived usefulness (β=–.375, <i>P</i>&lt;.001) and behavior intention (β=–.297, <i>P</i>&lt;.001). Personal innovativeness had a positive influence on perceived ease of use (β=.241, <i>P</i>&lt;.001) and a slight effect on behavior intention (β=.124, <i>P=</i>.001). Age (<i>χ</i><sup>2</sup><sub>58</sub>=133.5, <i>P</i>&lt;.001) and usage experience (<i>χ</i><sup>2</sup><sub>58</sub>=82.5, <i>P</i>=.02) had a slight moderation effect on the paths.

CONCLUSIONS

Perceived usefulness and perceived risk have significant effects on public intention to use e-consultation. Therefore, platform and manufacturer must improve the function of e-consultation, which will promote the public intention to use e-consultation fundamentally. In order to control the perceived risk of public, government should play an important role in enforcing management of e-consultation markets and approving corresponding medical insurance policies. Besides, personal innovativeness had an effect on behavior intention. Moreover, the paths of factors had some heterogeneity among people with different characteristics. Therefore, it is necessary to adjust the strategies to fit more groups better.
