In the fast-paced environment of Tan Tock Seng Hospital (TTSH), every moment is crucial for the dedicated nursing staff. Recognizing the pressing need for more efficient patient monitoring systems, TTSH has embraced cutting-edge artificial intelligence (AI) technology to enhance patient care and alleviate the workload of its nursing team.


Introduced in 2022, the innovative AI system, known as PreSAGE, represents a significant step forward in patient monitoring technology. Designed to predict patient movements and potential safety hazards, PreSAGE utilizes advanced thermography and video analysis to detect heat patterns and monitor patient activity within hospital rooms.


Nursing technology reduces nurses' workload and improves patient care


Before the implementation of PreSAGE, nurses in the hospital were tasked with manually setting up fall sensor mats for patients at risk of falls. However, these mats were not only time-consuming to install but also prone to inaccuracies. With the advent of PreSAGE, nurses can now save up to 10 minutes per patient by eliminating the need for manual setup and daily inventory checks on fall sensor mats.


The PreSAGE system operates by attaching a sensor to the wall above the television in each patient's room, providing a comprehensive view of the room's surroundings. Using sophisticated algorithms, the system establishes "boundaries" within the room, defining safe areas where patients should remain. When a patient exits their bed and crosses these boundaries, an alarm is triggered, alerting nurses to respond promptly to the potential safety risk.


One of the key features of PreSAGE is its ability to provide early warning signs of potential hazards before they escalate into serious incidents. By analyzing patient movements and heat patterns, the system can predict when a patient might need assistance, allowing nurses to intervene proactively and prevent adverse events.


Moreover, PreSAGE offers a user-friendly interface and a centralized dashboard that allows nurses to monitor patient activity and adjust boundary settings from any computer. This seamless integration of technology into daily nursing workflows enhances efficiency and enables nurses to prioritize patient care tasks effectively.


Currently deployed in 84% of TTSH's single and isolation room wards, PreSAGE has garnered positive feedback from both nurses and patients alike. Nurses appreciate the system's ability to streamline their workflow and reduce the burden of manual monitoring tasks, while patients benefit from enhanced safety and peace of mind knowing that their movements are being monitored discreetly.


Looking ahead, TTSH aims to expand the implementation of PreSAGE to all wards by the end of March, with ongoing testing to assess its effectiveness in rooms with multiple patients. As technology continues to evolve, PreSAGE represents a significant advancement in patient monitoring systems, paving the way for safer and more efficient healthcare delivery in the modern age.
