A small delay of the Intensive Care Unit (ICU) patient deterioration recognition can cause a permanent disability or even death. Therefore, patient monitoring is the most critical process in ICU. Human-related monitoring failures mostly cause delayed recognition of ICU patients. A higher workload in ICU leads to health professional burnout that could result in lousy healthcare quality. Internet of Things (IoT) implementation in the ICU monitoring process is expected to reduce the health workforce’s workload and patient monitoring process time. This paper aims to improve the operational process of ICU monitoring through IoT implementation with the Business Process Reengineering (BPR) approach in one of Jakarta’s private hospitals. The Complex Proportional Assessment (COPRAS) method is used to prioritize the risks of the current monitoring process to select the suitable IoT. This research proposes three business process models that utilize IoT-Based Patient Monitoring, Intelligent Monitoring Analytics, and a combination of both. A combination of IoT-Based Patient Monitoring and Intelligent Monitoring Analytics results the greatest process time reduction at 37.10%. Intelligent Monitoring Analytics results the smallest process time reduction at 11.56%.
