# Integrative Factors of E-Health Laboratory Adoption: A Case of Indonesia
## 3 Research Model and Hypotheses
### The Technology Driven Issue  
Information quality can contribute to user satisfaction because users can find out information about the quality of the system [58]. The quality of the system is in the form of the use of the most advanced technology, advantages in system functions and key features and software that is easy to use, easy to learn, easy to maintain, and user-friendly [82]. Users target quality information system content in the format, understanding, relevance, accuracy, accessibility, completeness, adequacy consistency, consistency, and timeliness, as described in the research [83; 84; 85; 86]. The relationship between information quality and perceptions about ease of use and system usability has often been used as a research model [70; 87; 88; 89; 90] where the research shows that the relationship of information quality positively influences perceived usefulness and perceived ease of use. E-health laboratories are predictable in providing information that is appropriate to the needs of the users, accurate, up-to-date, complete, clear, and in a good format, so users can consider adopting systems in e-health laboratories. To find out the relationship between the quality of e-health laboratory information and perceptions of ease of use and system usability, the supporting hypotheses are proposed:  
**Hypothesis 5 (H5). **_Information quality in e-health laboratory system positively influences perceived usefulness._  
**Hypothesis 6 (H6). **_Information quality in e-health laboratory system positively influences perceived ease of use._  
Accessibility in this research follows [PERSON] et al. [57]. E-health laboratories can be well adopted by users if they have a system that is accessible and can be used as easily as a conventional health check. Systems that experience problems when accessed mean that they have obstacles in the use. Whereas, a system that is easily accessed and has no constraints in the use will be the user's choice to be more frequent and easier to use [91]. The system can be accessed without a hitch if there is a fast internet connection and the right technical infrastructure, so that accessibility is not hampered. Users tend to ignore the system if there are obstacles to the network connection and internet speed [92; 93]. The reliability of system accessibility is an important factor. The model used to predict the adoption of the use of systems related to TAM in studies [94; 95; 96; 91] states that system accessibility has been considered a significant external factor. In e-health laboratories, it is suspected that the technical aspects of accessibility such as e-health laboratories can be accessed anytime and anywhere. E-health laboratories can be accessed under any conditions and can be accessed through various media (smartphones, laptops, etc.) This technical accessibility is a critical success factor that determines the usefulness of the system and the usefulness felt by users in adopting an e-health laboratory. Then the following hypothesis is formulated:  
**Hypothesis 7 (H7)**. _Accessibility in the e-health laboratory system positively influences perceived usefulness._  
**Hypothesis 8 (H8)**. _Accessibility in the e-health laboratory system positively influences perceived ease of use._  
The design in this research follows [PERSON] and [PERSON], 2016 [56, 58, 97]. Design becomes an important thing if it is associated with user adoption in a system. Design is prepared with careful consideration. Many studies on design evaluations such as [PERSON] et al. [98] present an evaluation designed to assess the quality level on mockup design of medical web application. The Design Usability Evaluation (DUE) technology can be used to find problems that affect navigation and ease of use of web applications [99]. The aim of this research is to improve the usability and usefulness of the system perceived by users. User-friendly design will provide usefulness and usability perceived by users [100]. Among the attitude factors, aesthetics and design have the most significant effect [101, 102].
