Internet of Things (IoT) can be a solution for hospitals to improve the efficiency and quality of operational services, however with technical and non-technical barriers such as costs, organization, and experience of users when using IoT, it cannot be implemented directly in all parts of the hospital. The aim of this study is to establish a framework to prioritize which hospital units to be implemented the Internet of Things (IoT) technology based on their current performance. This research used DEMATEL (Decision-Making Trial and Evaluation Laboratory) based ANP (Analytical Network Process) method to calculate the influence weight between factors. VIKORRUG (VlseKriterijumska Optimizacija I Kompromisno Resenje for Ranking Unimproved Gap) method was used to analyze the performance gaps in 9 units at a private hospital in Jakarta. Based on the results of calculations, the Emergency Room (UR3) has the highest priority to be implemented with IoT. After doing four scenarios of extreme circumstances, it was found that the One-Day-Care has the highest priority to be implemented with IoT instead.
