Objective: An electronic system for medical inventory management can increase the convenience and accuracy of information flow, facilitate systematic management, and control costs. System functions and interface operations that effectively increase convenience and efficiency significantly influence the quality of these systems.Methods: This study used the EB-SERVQUAL scale modified to fit the circumstances in each hospital. In-depth interviews were conducted with system users and administrators to determine target indicators. The analytic hierarchy process (AHP) method was then used to assign different weights to each assessment dimension in order to determine the importance of each indicator.Results: Based on the results of the AHP analysis, four dimensions, each with three indices, were identified for evaluation. The four dimensions were ”reactivity,” ”reliability,” ”connecting function,” and ”management level.” The weighting for each dimension was: 0.143 for reactivity, 0.142 for reliability, 0.385 for connecting function, and 0.330 for management level. The interview results indicated that the understanding of managers and users regarding the electronic medical inventory system differed. Most users believed that introduction of the system improved personal work efficiency and work performance. The managers believed that management of medical supply inventory was enhanced, and the hospital's internal resources were combined more effectively.Conclusions: This study used AHP to determine the importance of factors necessary for the modification of medical supply inventory control systems. These results, combined with the interview data, were used to identify strategies that hospitals could implement to improve the function of inventory control systems. These suggestions include increased dependence on internet connectivity, the development of online inquiry mechanisms, and the establishment of direct repair mechanisms with outsourced system vendors. These recommendations may increase overall user satisfaction and operational efficiency, improve the control and management of costs, and enhance patient safety.
