Evaluation Study for an ISO 13606 Archetype Based Medical Data Visualization Method.

The objective of this evaluation study is to assess a method for standard based medical data visualization. The method allows flexible and customizable visualization for ISO 13606 archetype based medical data. The chosen evaluation concept is based the Guideline for Good Evaluation Practice in Health Informatics (GEP-HI). The stages of the study were identified. Each stage got a detailed description. We also identified the participants and their required qualifications and responsibilities. The evaluation location was described in details. The evaluation metrics were defined. The questionnaires for doctors, patients and experts were developed to fulfill the requirements of the evaluation study. The study was performed in Tomsk, Russia. 30 patients and 5 doctors participated in the study. The overall performance of the users reached the expert level by the end of the study. Patients as well as medical staff stated in their comments that the usability of the system was high, and they preferred it to the previously used paper-based and computer based systems. This was also shown by the high level of satisfaction measured within our study. The visualization approach, integrated into the electronic health record, was well accepted in our pilot setting with high usability scores from patients and doctors alike. The results showed the efficiency for both modeling and visualization part of the system.
