Notable AI showcase

1) Survey on Gastroenterologists' Trust and Acceptance of AI: An international study led by LKCMedicine surveyed 165 gastroenterologists and gastrointestinal surgeons in the Asia Pacific region and found that gastroenterologists generally trust AI tools for diagnosing digestive diseases.

Published in the scientific journal JMIR AI,findings from the study highlighted that more experienced doctors showed more confidence and discernment about addressing AI risks,in comparison to younger doctors.

2) Increasing the accuracy and reliability of large-scale study of proteins: High-throughput technologies for measuring genes,proteins,and metabolites are vital for advancing our understanding of biological systems and discovering novel biomarkers and drug targets. However,the data generated from these technologies in proteomics—the large-scale study of proteins—is complex,high-dimensional,and requires extensive processing.

A study led by LKCMedicine tested over 34,000 workflow combinations on reliable datasets,uncovering consistent patterns among the top-performing workflows and demonstrated their predictability. Using this information,the team developed machine learning models capable of accurately predicting optimal workflows and introduced a novel method called "ensemble inference," which integrates results from the best workflows to enhance coverage and resolve inconsistencies.

The study,which is published in Nature Communications,is the first to highlight AI's role in optimising data processing workflows,and underscores that AI not only enhances data quality assurance but also plays a critical role in ensuring the generation of high-quality models by starting with high-quality data.

3) CHAMP Program: This initiative promotes chronic disease management through an automated chatbot that calculates the patient's risks and provides personalised nudges to patients. The program is integrated with patient's electronic health record and supports patients,clinicians and care coordinators to provide population scale community-based care for chronic diseases. Developed by NUHS,CHAMP uses whatsapp nudges to support patient self-management in chronic disease and to encourage healthier lifestyles. It enables patients to effortlessly submit vital signs readings like blood pressure,sugar readings and other information via the whatsapp-based chatbot and is seamlessly integrated into the patient's medical record for continuity of care.

More about this the CHAMP Chatbot

Dr Wayne Han Lee,Assistant Group Chief Technology Office of NUHS,CHAMP program lead and family physician at the National University Polyclinics shared some benefits of the whatsapp-based chatbot:

CHAMPcan remind patients to input their blood pressure throughout the week. Dr Lee said,"Currently,patients would write their blood pressure readings on a piece of paper,and I've got to spend time trying to make sense of it. But with this chatbot,the patient's data is recorded in our system,and it shows me immediately what their maximum,minimum,and average blood pressure trend during the week. So,I can spend more time talking with our patients to find out more about them,rather than staring at a computer screen keying in and looking for information."

This chatbot serves a dual purpose in that it not only offers clinicians a more efficient way of processing information,but also provides patients with an easier way of recording their medical information.

With more than 9,000 NUHS patients currently enrolled on the CHAMP program,Dr Lee hopes to extend CHAMP to over 150,000 patients with one or more chronic diseases. While this chatbot has currently been rolled out within NUHS,Dr Lee shared,"We want to extend this automation service to all patients,GPs and doctors across the country".

4) Novel ethics assessment tools for AI applications in healthcare: the development of the Transparent Reporting of Ethics for Generative AI (TREGAI) checklist and CARE-AI consensus research are two key achievements of Duke-NUS' DAISI initiative. A pioneering tool that standardises ethics assessments for implementing GenAI in healthcare settings,the TREGAI checklist helps to mitigate ethical concerns identified during the researchers' scoping review of existing discourse on GenAI use. The CARE-AI consensus,an ethics assessment tool that is currently being developed by DAISI,will ensure that AI prediction models are implemented in a fair,trustworthy and ethical manner to improve patient care. Considering various factors,including disease conditions and geo-economic contexts,it will guide healthcare professionals across the different stages of making medical decisions involving AI.

5) RUSSELL-GPTis a secured clinical large language model tool platform for healthcare that features multiple large language model tools for healthcare use. It is designed and customised for a wide variety of clinical tasks that supports clinicians in reduce their administrative workloads.

Project APOLLO will soon be testbeded in three healthcare clusters (i.e. SingHealth,NUHS and NHG).

8) SingHealth implements Note Buddy to transform clinical documentation and enhance the quality of doctor-patient interactions. All healthcare professionals across SingHealth institutions will progressively be onboarded to Note Buddy which aims to significantly reduce administrative burden by transcribing and summarising clinical notes in real-time during physician-patient conversations. This allows clinicians to dedicate time during each consultation to interacting with patients and their caregivers to better understand and address their health concerns and questions.

More about Note Buddy

Note Buddy's key feature is its ability to automatically detect,transcribe and summarise conversations in multiple languages (English,Mandarin,Malay and Tamil) between the clinician and patient during clinic consultations into accurate clinical notes using customised prompts that structure how the clinical note is summarised. Speaker diarisation allows Note Buddy to differentiate multiple speakers and identify their role based on the context (e.g. Doctor,Patient,Caregiver). Developed by SingHealth's Division of Digital Strategy,Note Buddy is launched on Tandem,a Secure Generative Pre-trained Transformer (GPT) platform developed by Synapxe,Singapore's HealthTech agency.

Currently,healthcare professionals document clinical notes during consultations with patients. Note Buddy heralds a paradigm shift in the way clinical documentation is done. Before the consultation,clinicians can select a customised prompt in Note Buddy to tailor the format of the notes to their specialty.

For instance,an endocrinologist can use Note Buddy to document patient-reported insights,diabetes and thyroid assessments,as well as cardiometabolic management plans during consultations,ensuring that these key pieces of information are captured. Note Buddy extracts and summarises the relevant information shared during the doctor-patient conversation into clinical notes in real time. Clinicians can review the notes immediately after each consultation to ensure that the necessary information has been accurately documented. This process enhances the timeliness,completeness and accuracy of each clinical documentation.

Note Buddy also has capabilities beyond clinical consultations including text summarisation. Clinically,it assists in summarising clinical notes into various structured documents such as discharge summaries and medical reports. On the administrative front,Note Buddy can handle administrative tasks like drafting meeting minutes. This expansion of its capabilites streamlines both clinical and administrative workflows,reducing the documentation burden on healthcare professionals and administrators.
