Objective: We assessed primary care providers' perception of a health information exchange system (HIE) based on IHE XDS in the metropolitan area of Braunschweig, Lower Saxony, Germany.
Design: An application enabling access to medical documents in an XDS Affinity Domain was developed. We examined usability and factors related to user acceptance.
Measurements: User perception was probed using system usability scale (SUS) and semi-structured interviews. The framework analysis was used in the review and interpretation of the interview data.
Results: The evaluation was performed on 7 participants. The SUS showed an above average usability with a median score of 77.5. Participants submitted suggestions for additional features and improvement of usability. Poor integration of functionality into existing workflows was most frequently criticized.
Conclusion: We found, that, while usability was well perceived by primary care providers, challenges remain in adoption of XDS based IHE.
