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

[Purpose/Significance] Exploring the accessibility of health information services for the elderly in a digital intelligence environment can provide effective protection for the construction of healthy aging, and exploring its influencing factors and relationships is of great significance. [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. Therefore, suggestions are proposed to optimize the allocation of health information resources, guide the construction of aging services, and improve infrastructure construction.
