ABSTRACT

Background:

Osteoporosis-related fractures significantly impact older adults, often leading to disability and even premature death. While pharmacological and non-pharmacological interventions are widely recommended for managing osteoporosis, adherence to these interventions remains low. To address this challenge, we developed the Healthy Bone digital platform (desktop, mobile application, and smart TV internet-based) for use in clinical settings to improve disease management and treatment adherence. It integrates a multimedia health-related behavioral change program with a patient monitoring and management system.

Objective:

This study aimed to evaluate the usability and user experience of the desktop version of the Healthy Bone digital platform prototype from the patients’ perspective. The findings will provide valuable insights into optimizing the digital platform and enhancing its functionality.

Methods:

A mixed-methods study was conducted. During usability testing, patients completed tasks simulating real-world use of the platform while employing a Think-Aloud approach. After each task, participants filled out an After Scenario Questionnaire to assess task satisfaction. Subsequently, participants completed the System Usability Scale (SUS) and the eHealth UsaBility Benchmarking Instrument (HUBBI) to measure usability quantitatively. Following this, semi-structured interviews were conducted to explore participants’ experiences with the platform in greater depth. Descriptive statistics were used for quantitative analysis. Qualitative data analysis involved a combined deductive and inductive approach, ensuring a comprehensive evaluation of the platform’s usability and user experience. Deductive content analysis was guided by an ontology of eHealth usability components, while thematic analysis adhered to Braun and Clarke’s method to identify emerging themes.

Results:

Seven participants evaluated the digital platform, reporting high usability with a mean overall SUS score of 87.1 ± 13.3. Similarly, good usability was reported across all categories of the HUBBI, except for the Guidance & Support category, which presented moderate levels of usability (3.3 ± 1.1). Patients reported high levels of task satisfaction and identified 24 unique usability issues, predominantly related to the Basic System Performance, Interface Design, and Navigation & Structure categories of the eHealth usability ontology. Overall, patients had positive perceptions and acceptability of the digital platform, highlighting its simplicity, accessibility, utility, and potential to empower those with osteoporosis. Barriers to usage included limited skills, lack of suitable equipment, and time, while facilitators included motivation for behavior change, health benefits, and the decrease of potential inequalities.

Conclusions:

This study provided valuable insights into the usability and user experience of the desktop version of the Healthy Bone digital platform prototype. These findings will play a key role in optimizing the platform to ensure it is effectively tailored to the needs of the target population. This platform adds an understanding of how various ICT tools can support and benefit large numbers of patients in society, as the project can easily adapt to other diseases and populations.
