13 July 2023

The healthcare landscape will continue to face challenges presented by an ageing population, complexity of care and a tight workforce.

Signalling the urgency to tackle these challenges by embracing innovations and technology rapidly and meaningfully, Tan Tock Seng Hospital (TTSH) introduced its “Future Ward Prototype” to the media today.

Falls preventing smart beds, delivery robots, predictive sensors are just some of the many innovations already in operation inside ward 5C - The Smart Ward.

Started in late 2022, right after the impact of the COVID-19 pandemic and amidst higher staff workload, the Smart Ward re-imagines the future state of inpatient care by adopting a sandbox approach to rapid test-bed innovations in a real-world patient environment.

The Smart Ward leverages digitalisation, robotics, and artificial intelligence to change the way care teams work and care for patients. Here, care is designed to be more predictive, empowering, and automated enabled by multi-disciplinary team.

Bridging the Innovation to Adoption Gap

Despite the healthcare innovation landscape constantly evolving with new technologies, there is often a gap and lag-time from the development of new solutions to their adoption and implementation in healthcare settings.

It is a challenge to prioritise which solution to adopt and when to scale, due to the highly regulated environment, tight resources in healthcare and a lack of a unified framework that could stringently evaluate, fund, procure and scale innovations.

Moreover, hospitals are large and complex, and different stakeholders has different priorities which makes it difficult to reach a consensus on solutions to test onboard. A ground-up innovation may take years before it can be scaled to the other wards.

To test fast, learn fast and scale fast, the Smart Ward team leverages on a robust framework that test-beds design, collects data, analyse costs and risks to evaluate solutions for adoption. These projects are backed by important internal stakeholders such as Operations, IT, Finance and Procurement to coordinate, green lane and accelerate suitable innovations.

Explaining how the adoption gap is tightened, Ms Lim Mei Ling, Smart Ward Lead and Senior Nurse Manager, TTSH, stressed the need for all stakeholders to be in close proximity. She said, “The Smart Ward is helmed by a multi-disciplinary care team of doctors, nurses, allied health professionals and administrators aligned in their aims of bringing value to both patients and staff. We’ve been given the agility and autonomy to ensure collective decisions – to scale or not to scale further – can be made and implemented fast and safely without being belaboured by conventional approval processes.”

Patients, caregivers, and visitors as end users also play a critical role on the adoption of innovations, through their feedback.

The Smart Ward team is supported by the Ng Teng Fong Healthcare Innovation Programme (NTF HIP) which is managed by TTSH Community Fund and Centre for Healthcare Innovation.

Real-life Test Bed

“Smart Ward predominantly manages general medicine patients who are mainly elderly with most complex of needs. As a hospital with high ambitions for the transformative benefits of innovation, it is important that our ideas are test-bedded in the most real and intensive of environments and not in extended spaces”, said Smart Ward Co-Lead and Associate Consultant, General Medicine, Dr Keefe Tan. “Real problems are explored and exposed this way and we can then realise the proofs of concept and value of these forward initiatives for our patients and workforce.”

Test Fast, Learn Fast and Scale Fast

The Smart Ward is imperative to the way the hospital strengthens the re-design of care and work processes.

“As our society becomes older, so will our patients and our workers. It is crucial that we leverage on innovation to tackle new determinants of health such as frailty and create a nimbler workforce not burdened by repetitive and labour-intensive tasks. Innovation is no longer a wait and see luxury, but one that is mission critical. As such, initiatives and ideas in Smart Ward are constantly being rapid tested, re-purposed and planned for scaling up,” said Dr Hoi Shu Yin, Chief Nurse, TTSH.

One such initiative is the SMART Predicative Patient Monitoring System known as PreSAGE®. Powered by artificial intelligence, it uses thermography, machine learning, predictive algorithms, and image processing techniques to detect and predict bed-exits. A 15-second pre-exit lead time is allocated for staff to intervene before patient assumes a standing position from the bed. Patients’ conditions can be monitored and even predicted remotely by these digital enablers for earlier interventions.

During evaluation, PreSAGE® achieved a sensitivity score of 100% for bed-exit prediction. There was a 34% reduction in falls rate, and a 67% saving in manpower hours. Since its implementation, PreSAGE® has been scaled to all single-bed and isolation rooms in TTSH which comprise a total of more than 100 beds.

Another project which is still in its early phase of trialling is the Doctors, Nurses, and Allied Health Professionals (DNA) hands-free communication technology. Its voice-to-text command function enables nurses to treat a wound and document the clinical procedure hands-free. Clinicians can also make timely and informed decision in patient care planning with the care teams by initiating a virtual video call discussion via the voice command without need to search through the phone directory or have him or her present at the bedside. Potentially, virtual ward rounds will be the norm where the care team members can dial in anytime, anywhere to discuss, not bound by time zone, resulting for a more efficient and nimbler workforce.

In the near future, the Smart Ward aims to redesign the role of the care team through techenabled care. Taking a proactive approach, the adoption of “Virtual Nurse” in the ward will assist bedside nurses in virtual monitoring, clinical admin and care surveillance. Bedside nurses can also use the voice activated wearable to allow the “Virtual Nurse” to view the procedure and provide clinical advice.

To date more than 20 innovations have been tested in the SMART facility, with 14 initiatives already introduced and in line to be scaled-up to other wards. In the next 1 to 2 years, another 20 initiatives are in line to be rapid tested.

The Smart Ward is the engine to a one of the hospitals Strategic Innovation Programme called Ward without Walls (WoW). WoW envisions care that is not only enhanced in the inpatient setting but joined up before and after a patient’s hospital stay.

Below are some examples of our innovations:



​Mere minutes and seconds can make a difference in our care team being able to deliver crucial interventions to save lives and prevent complications.
To anticipate falls, sensors and AI technologies are embedded in the ward with our multi award-winning PreSAGE bed-exit Prediction and Prevention system co-developed by CoNEX Healthcare and TTSH.

Using thermography, machine learning, predictive algorithms, and image processing techniques, PreSAGE® is powered by artificial intelligence to detect and predict bed-exits which allows a 15-second pre-exit lead time for staff to intervene before patient assumes a standing position from the bed. Patients’ conditions can be monitored and even predicted remotely by these digital enablers for earlier interventions.
During evaluation, PreSAGE achieved a sensitivity score of 100% for bed-exit prediction. There was a 34% reduction in falls rate, and a 67% saving in manpower hours.

Since its implementation, PreSAGE® has been scaled to all single-bed and isolation rooms in TTSH which comprise a total of more than 100 beds. The next phase of evaluation will be to test-bed this system in TTSH Smart Ward’s cubicle room of 6 beds. As well as, to explore advanced contactless sensors that will monitor patients’ parameters such as respiratory rate, temperature, behavioural and emotional state to predict deterioration of condition for early intervention.

PreSAGE® has also been adopted by other hospitals and nursing homes in Singapore after the successful pilot at TTSH.

The Doctors, Nurses and Allied Health Professionals (DNA) hands-free communication technology can empower clinicians to make timely and informed decisions. Virtual ward rounds will be the norm where care team members can dial in anytime and anywhere, even off-campus, for care plan discussions.

For instance, a doctor who needs to update on the patient’s condition or obtain input from other clinicians to define the patient’s care plan together can use this hands-free wearable technology. The device allows clinicians to issue voice commands, such as “Call Patient ABC’s Care Team”, to contact the relevant personnel for virtual discussions.

Its voice-to-text command function also enable nurses to treat a wound and document the clinical procedure hands-free. Especially relevant in today’s context during the COVID-19 pandemic where members of the care team have to gown and de-gown Personal Protective Equipment (PPE) to check on each patient, take his or her vital signs and administer medications periodically in an isolation room. With this technology, it can minimise material wastage.

Still on trial, the voice activated communication wearable can potentially save up to 8 seconds as compared to using a smartphone for calling another care team member. The additional step to search for phone directory reduces the calling time.



Activated patients are empowered to take charge of their own health.

Each patient in the Smart Ward will have a SMART Device (iPAD) at their bedside. It will allow patients to have real time access to their care team, personal health data as well as educational information.

Patients can find out more about their well-being and take charge of their own health, through their personal health data such as vital signs, as well as check for the schedules of their next medical and/or therapy sessions.

Patients and caregivers can also learn more about their conditions and be equipped with the necessary skills to better manage their care in the community when they are discharged.

The current ward has work counters in the middle of the ward to facilitate documentation by staff. As we have transited to electronic medical records and digitisation of records, and documentation mainly at the decentralised counters, the space can now be re-purposed as a healing space in the inpatient ward.

With the space redesign, it caters as a multi-purpose space for optimised for patient engagement, team interactions, virtual team conferencing and future evolving needs. Thus, creating more space to empower patients to partner with their care team in caring for their own health.

Practising good hand hygiene is important to serve as protection surveillance to patients, staff, and visitors themselves.

The use of voice prompts is to remind staff and visitors to carry out hand hygiene when they enter the wards.

It is a ground up initiative by the nurses. With the implementation of the Hand Hygiene Reminder, there has been 50% more hand hygiene completed when staff and visitors enter the ward.

The assisted shower device supports nurses in showering patients who are functionally dependent and at risk of fall. There are smart water jet spray and self-shampooing capsule to bathe the patient.

With this shower device, one nurse nstead of the usual two nurses is now needed to assist the patient. It reduces the time for patients to shower, from 10 mins to 4 mins, improving nurses’ productivity by 60% so that they can do more value-added work.

Patients feedback that the device’s showering process is thorough and complete. With patient safety and privacy ensured, this device has since scaled within the hospital.

Allows for safely disposal of single use pulp consumables such as bedpans and urinals that contains human excreta. Compared to bedpan sanitizers, the macerator is able to significantly reduce the risk of cross contamination to meet higher infection control standards, especially critical during an outbreak.

It is environmentally friendly, improves hygiene and saves the need for nurses and health care attendants to wash the consumables.

​Co-designed with Cadi Scientific and TTSH, RTLS provides the foundational locating technology, that allows us to locate patients and equipment in real-time. The RTLS will enable the tracking of patients, visitors and staff, for rapid and reliable contact tracing so that necessary actions can be taken quickly to curb onward transmission.

RTLS was implemented in National Centre for Infectious Diseases (NCID) in 2019 and has scaled to the TTSH’s main ward block in 2023. TTSH Smart Ward also redesigned the process for patient abscondment leveraging on RTLS. For example, in the event of patient abscondment, staff can locate patient immediately to ensure patients’ safety.
RTLS provides us the capability of real time location tracking and contact tracing which allowed us to:

  • Improved operational efficiency
  • IOptimised asset management
  • Enhanced and expedited contact tracing
