SingHealth And A*STAR Co-developed Smart Chatbot To Enhance Care For COVID-19 Patients At Community Care Facilities

SingHealth and the Agency for Science, Technology and Research (A*STAR), with support from the Integrated Health Information Systems (IHiS), have co-developed a chatbot known as “Doctor Covid” to improve care for COVID-19 patients at community care facilities. Hosted on the Telegram mobile application, Doctor Covid boasts a variety of features in the patients’ native languages to facilitate effective communication, active engagement and interaction, and to support the medical and operations teams in close monitoring of their health and well-being.

Community care facilities house COVID-19 patients who are clinically well and no longer require acute care, as well as newly confirmed cases with mild symptoms who do not require hospital care, the majority of whom are migrant workers presently. Providing personalised, one-to-one care to large groups of residents at these recovery facilities can be challenging, and this is compounded by operational challenges such as language barriers between the medical teams and migrant workers.

Doctor Covid has been purposefully developed and used at such facilities managed by SingHealth at Singapore EXPO and D’Resort since May 2020. It complements the care provided by onsite medical teams to ensure that each resident is able to access the right care anytime they need, from identifying symptoms such as chest pain or shortness of breath early, to supporting their psychosocial well-being by allaying any uncertainties or anxieties they may face during their recovery. To date, more than 3,000 migrant workers staying at SingHealth-managed community care facilities, have subscribed to the chatbot.

Key Features Of Doctor COVID

A*Star researchers worked with the SingHealth team to develop and implement the following features:

01. Multi-lingual platform

Multi-lingual platform

Doctor Covid features up to seven different languages that migrant workers can subscribe to – English, Mandarin, Malay, Tamil, Bengali, Thai and Burmese. Currently, the languages enabled are English, Mandarin, Malay, Tamil and Bengali. Having migrant workers interact with the chatbot in the languages they are familiar with keeps them engaged and ensures that they receive and understand the content that is communicated to them. It also ensures greater accuracy in the information they submit via the chatbot, such as responses to questions about their well-being.

02. Broadcasting of critical information and reminders

Broadcasting of critical information and reminders

Doctor Covid disseminates critical information including medical, nursing, and operational announcements, as well as reminders to submit vital signs inputs such as daily temperature and blood pressure readings. These are communicated on a daily basis to ensure that the workers are kept abreast of the situation and understand their recovery journey.

03. Sharing of social content

Sharing of social content

The chatbot helps keep residents engaged and entertained during their stay through the sharing of social content such as movies, exercise videos, simple games and even video clips featuring words of encouragement from celebrities in various languages. These materials, which include original content developed by SingHealth staff, are carefully curated, and where necessary, translated by staff volunteers, prior to dissemination.

04. Clinical and psychosocial surveillance

Clinical and psychosocial surveillance

Migrant workers use Doctor Covid to respond to questions that assess their clinical risk factors and mental well-being. This is done through easy-to-understand questionnaires with audio capabilities on a daily basis, or at specific milestone stages of their stay at the facility. For example, on Day 7 and Day 14 of their stay, they respond to Doctor Covid’s questions such as “Are you scared?”, “Are you sad?” to assess their holistic well-being. The data is then sent to SingHealth’s patient experience teams who ensure timely psychosocial intervention where required. The data collected will also facilitate further AI-driven diseases triaging, progression and clinical outcome prediction.

[Next phase] Conversational AI chatbot

Using artificial intelligence (AI) such as machine learning, natural language processing and optical character recognition, Doctor Covid will be able to capture, analyse and respond to complex COVID-19-related questions posed by migrant workers in their respective native languages. This will be launched later this year.

Beyond enhancing care and communication, Doctor Covid helps minimise the risk of viral transmissions. With communication and monitoring of residents taking place virtually, medical teams reduce prolonged face-to-face contact with COVID-19 patients and the time spent in the “red zone” of the care facilities, while ensuring that comprehensive care is continued.

The data collected by Doctor Covid, which is anonymised to ensure data privacy, can also be used to identify trends, risk indicators, clinical outcomes, as well as evidence-based practices as a study into the COVID-19 pandemic and care of migrant workers, as well as to prepare for future infectious disease health emergencies. Moving forward, data from Doctor Covid may be integrated with other COVID-19 data platforms and registries to form a big data platform with AI analytical tools for operational and research purposes.

The experience of being diagnosed with COVID-19 can be a stressful one, especially for migrant workers who are uncertain as to what to expect and may face language barrier issues with the healthcare workers caring for them. At the same time, it is no easy feat for medical teams to take care of large groups of residents in community care facilities. Doctor Covid leverages innovation and technology to better reach out, engage and care for these residents, while allowing healthcare professionals to gain better insight into how each resident is doing in their recovery. We will also be deepening the sophistication of the platform by incorporating AI mechanisms into Doctor Covid and establishing a stronger two-way interaction with residents, while at the same time be able to utilise the data collected for research purposes,” said Franklin Tan, Director, Office for Service Transformation, SingHealth.

“We are pleased that our capabilities in system architectural design, software engineering, and data science were able to support SingHealth in its sterling efforts to provide quality care to recovering workers at the community care facilities. Through close collaboration, A*STAR and SingHealth were able to harness digital tools and artificial intelligence to develop this tool to facilitate better communication and engagement with the recovering workers, as well as generate data insight for the medical teams,” said Dr Rick Goh, Department Director, Computing & Intelligence, Institute of High Performance Computing (IHPC), A*STAR.

This is a good example of the research, patient service and technology teams working collaboratively, at speed, to address a patient need. IHiS is proud to be part of the team,” said Steve Lee, one of the advisors to the project team, and Deputy CEO, IHiS.

Doctor Covid has also been well-received by residents staying at the community care facilities. Of more than 167 patients surveyed, 97% were satisfied with the chatbot. 73% found the daily medical reminders useful and 78% appreciated the health and wellness tips. More than 84% also indicated that they felt cared for because of the chatbot. Mr Velusamy Santhosh, who has been staying at CCF@Expo for about two weeks said, “I’m very happy with Doctor Covid as it is very useful. It reminds me to monitor my health, and I follow its health and wellness tips. I feel safe and well taken care of with Doctor Covid.”
