Human-Centered Design of Tool Support for Managing Oral Anticoagulation

The Perioperative and peri-interventional management of oral anticoagulation are major clinical challenges with respect to stroke and bleeding risks in various interventional and surgical procedures. This paper illustrates the human-centered (re-)design of computer-based tool support providing individualized treatment concepts for patients. Considering pragmatic and hedonic aspects of usability and user experience, both the original and the revised version were evaluated with 20 medical experts each. Results of the User Experience Questionnaire (UEQ) and numbers of necessary interaction steps for task completions indicate that usability and user experience have been improved by the applied human-centered design measures. Therefore, this paper exemplifies the effects of systematic human-centered design efforts on usability and user experience as crucial aspects of patient safety, workload of medical professionals and long-term acceptance.
