Factors influencing use of eHealth services during and after the COVID-19 pandemic.

ObjectivesThe rapid advancement of information and communication technologies has made eHealth applications increasingly available and accessible. The COVID-19 pandemic has accelerated the need for remote health service provision. This research aims to explore the usage, perceptions, and knowledge of eHealth interventions during and after the COVID-19 pandemic.MethodsA cross-sectional survey was conducted in 2021 (during the pandemic) and 2023 (post-pandemic) using a structured questionnaire based on the Technology Acceptance Model (TAM) and the eHealth Literacy Scale (eHEALS). The survey, conducted in Greece, included 638 participants in total (277 in 2021 and 361 in 2023). Structural equation modeling was employed to assess the factors influencing eHealth adoption.ResultsThe findings indicate a slight increase in positive perceptions of eHealth usefulness, intention to use, and actual usage over the 2 years. However, concerns remain regarding the ease of use and eHealth literacy. eHealth literacy significantly predicts the perceived usefulness and ease of use of eHealth services, both of which predict the intention to use them. Additionally, higher education levels are positively associated with eHealth literacy, while older age is negatively associated with ease of use. Gender did not significantly impact these factors. These findings were consistent across both surveys.ConclusionsPolicy-makers should focus on simplifying eHealth services, removing technical barriers, and enhancing the population's eHealth literacy to promote wider adoption of eHealth services.
