Study on the factors influencing the accessibility of health information services for the elderly in a digital intelligence environment

[Method/Process] Based on the information ecology theory, influence factors are extracted from four dimensions: information, information people, information environment, and information technology.

The DEMATEL method is used to identify key influence factors, and the hierarchical structure and correlation path of key influence factors are determined through the ISM method. [Results/Conclusion] The results indicate that four root factors, namely, data storage technology, information coordination and sharing, policies and regulations, and communication infrastructure, as well as two surface factors, namely, demand fit and service stability, have an important impact on improving accessibility.
