The aim of this study was to evaluate the usability of the ADT system in some of selected Iranian non-teaching hospitals.MethodsThis study was a cross-sectional research that has evaluated the usability of a selected ADT system using the think aloud method by 11 medical record administrators. Users were asked to follow the provided scenario, then share and elaborate on what they saw, thought about, did, felt, and decided during their interaction with the system. Users' feedbacks were collected and organized into four main categories for further processing.ResultsTo evaluate the ADT system’s usability, four routine scenario tasks were followed by users and only 45.45% of them could implement all task. In overall, 36 independent problems were identified. All problems were related to the data entry categories accounted for the largest share. Most problems in this category were related to the issues regarding "date of birth" field which deal with the outpatient admission process.ConclusionsOur study of the usability testing method indicated that the ADT subsystem of non-teaching hospital has enormous problems in interact real users with the system. It showed more than half of the users could not perform the entire real world scenario tasks related to completely and successfully. Furthermore, most usability problems were found in data entry categories.
