Abstract
Usability testing methods are nowadays integrated into the design and development of health-care software, and the need for usability in health-care information technology (IT) is widely accepted by clinicians and researchers. Usability assessment starts with the identification of specific objectives that need to be tested and continues with the definition of evaluation criteria and monitoring procedures before usability tests are performed to assess the quality of all services and tasks. Such a process is implemented in the p-medicine environment and gives feedback iteratively to all software developers in the project. GCP (good clinical practice) criteria require additional usability testing of the software. For the p-medicine project (www.p-medicine.eu), an extended usability concept (EUC) was developed. The EUC covers topics like ease of use, likeability, and usefulness, usability in trial centres characterised by a mixed care and research environment and by extreme time constraints, confidentiality, use of source documents, standard operating procedures (SOA), and quality control during data handling to ensure that all data are reliable and have been processed correctly in terms of accuracy, completeness, legibility, consistence, and timeliness. Here, we describe the p-medicine EUC, focusing on two of the many key tools: ObTiMA and the Ontology Annotator (OA).
Highlights
Usability is the measure of the potential of the software to accomplish the goals of the user including ease of use, visual consistency, and so on
The first feedback of end-users was collected in the first round of usability tests with external volunteers, a clinician, and a study nurse for ObTiMA and a data analyst for the Ontology Annotator (OA)
For the usability evaluation of p-medicine tools, an extended usability concept (EUC) was developed in the p-medicine project consisting of two approaches
Summary
Usability is the measure of the potential of the software to accomplish the goals of the user including ease of use, visual consistency, and so on (definition by TechTarget, http://searchsoa.techtarget.com/definition/usability). Software should support the user in his/her daily work, especially when various user groups are working with the same platform or tools This is a great challenge for the European research project p-medicine (http://www.p-medicine.eu), where a service-oriented clinical research infrastructure is under development to improve the prognosis of patients by paving the way to personalised medicine. GCP is an international ethical and scientific quality standard for designing, recording, and reporting trials that involve the participation of human subjects [4]. It ensures that the use of software tools does not lead to an increased risk for the patient, protects the patient’s rights, and guarantees the ethical conduct of research and the high quality of collected data
