Strengths and Weaknesses
Despite the precommercial nature of the digital health tools supporting each of the 2 feasibility studies, reasonably good usability and acceptability results were obtained in real-world clinical settings. The positive results reinforce the need to pursue the development of a commercial product with potential for cost-effectiveness and profitability in real-world settings.However, we must acknowledge several limiting factors of the studies, such as small sample sizes, the local health care settings, and the descriptive observational study design of study 2, which may preclude the generalization of the findings to other populations or health care settings.Finally, although one of the limiting factors for adoption of value-based care services is still acceptability and usability among stakeholders, especially older people, the reported studies contribute to the growing body of evidence that indicates the positive effects of eHealth services on patient health outcomes [
