Background: The diagnostic phase of the cancer journey, from suspicion to diagnosis, is a complicated process for both patients and physicians. The Diagnostic Assessment Program-Electronic Pathway Solution (DAP-EPS) shows patients and their primary care providers where they are on the journey to cancer diagnosis. This tool is designed to provide a coordinated approach to patient care from referral to definitive diagnosis by centralizing information and allowing the tracking of patients throughout the diagnostic journey.

Objective: The primary objective of this work was to explore primary care physicians' (PCPs) attitudes toward adoption of the DAP-EPS tool in their clinical setting. The secondary objective was to explore potential factors influencing perceived ease-of-use and usefulness of the tool.

Methods: To guide this study, an integrated theoretical framework that combined the theories of the Technology Acceptance Model and Diffusion of Innovation was used. An online survey was used to collect data from PCPs across the province of Ontario.

Results: Results from this study suggest a strong influence of perceived usefulness of the DAP-EPS on physicians' attitudes toward adoption of the tool. Findings also suggest that perceived usefulness is more important than perceived ease-of-use within the PCP context.

Conclusion: This exploratory study, although limited, supports previous views regarding PCPs' attitudes toward adoption of technology. The main lessons learned are that the perceived usefulness is the main predictor of PCPs' attitudes and that the management and implementation teams should emphasize the usefulness of DAP-EPS to increase adoption of the tool.
