| Popis: | 90 To a clinician’s work, he often needs to face various patients with different symptoms. A clinician often diagnoses a patient by the patient’s symptoms and the clinician’s professional knowledge and experience. Because of all clinician’s professional ability and experience are not the same, they may make different clinical decision even face the patients with the same symptoms. In these situations, the clinical decision support system (CDSS) will play an important role. CDSS can offer many important suggestions to clinicians. Because of the characteristics of CDSS, the outcome of CDSS relate to the user’s input. Different interface will affect the user’s input, so different interface will affect the outcome of CDSS. We purpose to evaluate usability of user interface of CDSS. We evaluate two user interfaces. First, the user offer information to CDSS by himself (like keywords interface). Second, CDSS presents all information to users (like menu selection interface). Usability of a computer system can be defined as the capacity of the system to allow users to carry out their tasks safely, effectively, efficiently and enjoyably. For evaluate the usability of interface of CDSS, we purpose to build an evaluation tool. This tool can randomize decide which interface that the test experts use. This tool can evaluate the usability of interface of CDSS in three points — efficiently, effectively enjoyably. Infectious Disease Clinician: infectious disease clinicians will commend keywords interface; other clinicians will commend menu selection interface. Clinicians will commend keywords interface; medical students will commend menu selection interface. Beginners will commend menu selection interface. |
