Abstract:Purpose: This research aims is to implement a new eHealth solution for eye-care at the University Medical Center Utrecht. Special attention will be given to the analysis of acceptance and adoption of telemonitoring services by patients. Approach: A structured literature review about telemonitoring acceptance is conducted before conducting this research. Based on the results, a telemonitoring acceptance framework (TAF) which is an extension of the “unified theory of acceptance and use of technology” is developed. Also, a survey measurement model is developed to measure the constructs in the framework. This survey is administered among different patient groups and non-patient groups to assess the framework. Four iterations of the framework are analyzed to improve the model fit and reliability. The best model is used for the Structural Equation Model path analysis. Based on the Design Science Research Methodology, a minimum viable product of an online eye exam is developed and implemented in the UMCU patient portal. This implementation is demonstrated and evaluated with a usability experiment. The MVP of the online eye exam is accessible via . Results & Conclusion Data for assessing the telemonitoring acceptance framework was collected in November and December 2019. After the four iterations of model improvement, the reliability and quality of the measurement model were maximized for further analysis. However, the model fit is acceptable but not very impressive. The structural model path analysis showed that Performance Expectancy is significantly influencing Behavioural Intention (beta=1.113, P=.021). Trust (beta=0.865, P<.001) and Effort Expectancy (beta=0.241, P=.007) are significantly predicting Performance Expectancy. And finally, Self-Efficacy is influencing Effort Expectancy (beta=0.915, P<.001). The evaluation of the MVP usability testing showed that the exam is hard to use for elderly people. They are less advanced in smartphone and computer use than we anticipated. Also, the instructions from the exam were hard to understand which resulted in catastrophic failures. Recommendations This research is the basis for a new telemonitoring acceptance framework. The framework and measurement model can be improved by having the survey translated by a professional, re-specifying or removing the questions with low internal reliability. Moreover, new data collection among a more homogeneous population will enable a more population-specific analysis of acceptance. The CORE-study will continue from January 2020 at the UMCU. This study will elaborate more on the usability, quality, validity and patient acceptance of the implemented online eye exam.
