National Taiwan University Hospital (NTUH) on Thursday presented its newly developed telecare system that uses artificial intelligence (AI) to predict the occurrence of patient-related emergency events by analyzing text conversations between patients and their live-in caregivers.
The “Intelligent Voice Emergency Prediction System of the Fourth-Generation Real-Time Synchronous Telehealth Care Platform” developed by NTUH and Chunghwa Telecom won the “21st National Innovation Award-Clinical Innovation Award” in November last year.
At a news conference, Ho Yi-lwun (何奕倫), director of the Department of Internal Medicine and Telecare Center at NTUH, said the system converts conversations between patients and caregivers into text, and could analyze keywords in conversations, such as blood pressure and other physiological data, for earlier predictions for emergency treatment, thereby reducing unnecessary complications in patient care.

Taking people with acute myocardial infarction as an example, Ho said if intervention occurs within the golden six hours for treatment, there is a chance occluded blood vessels could be recanalized.
The intelligent voice emergency prediction system could accurately identify people with emergency needs, distinguish between high and low-risk patients, and allow those with greatest need to receive necessary treatment quicker, he added.
This system would not only help reduce emergency room visit rates, but also the length of hospital stays and the risk of death, due to immediate medical responses, Ho added.
Hung Chi-sheng (洪啟盛), a doctor from NTUH’s Telehealth Center, said that since its establishment in August 2009, the Telecare Center has handled 540,000 phone calls and cared for more than 7,000 patients.
It cooperated with Chunghwa Telecom to introduce the telecom’s multi-language, medical speech recognition technology and conduct AI model training, which could recognize speech in Mandarin, English and Hoklo (also known as Taiwanese), Mandarin accents of migrant caregivers, medical terms, Chinese and English names of drugs, and convert the speech into text.
Through language processing and analysis of integrated nursing records, the AI system could monitor and predict the probability of people experiencing emergency events within two weeks of analysis, Hung said.
The system’s predictive accuracy rate is roughly 90 percent, he said.
Telecare could improve patients’ blood pressure, reduce mortality, reduce emergency room visits, and the number and length of hospital stays, Hung added.
Home-based telecare has become an important tool to address healthcare needs in Taiwan’s aging society, particularly during the COVID-19 pandemic, he said.
NATIONAL SECURITY: Authorities are working to confirm the identities of the military personnel involved and investigating possible illegal conduct and regulatory violations Authorities are probing possible national security implications after Kinmen police and immigration officers on Sunday found a Chinese woman allegedly posing as a tourist while engaging in prostitution involving more than 10 military personnel. The woman, surnamed Chen (陳), has since been deported, authorities said, adding that investigators are still working to confirm the identities of those implicated, as the records only listed code names and aliases. The case stemmed from a report received by the Kinmen District Prosecutors’ Office on Friday last week from the Jinhu Precinct of the Kinmen County Police Bureau. On Sunday, police, along with the National Immigration
GLOBALGIVING: ‘ Caving to external pressure is not acceptable for an organization that has cultivated justice reform and human rights for 30 years,’ one NGO said A slew of non-government organizations (NGOs) have withdrawn from the GlobalGiving fundraising platform after it announced it would use “Chinese Taipei” instead of “Taiwan” from next month. The Taiwan Good Rice Association wrote on Facebook on Friday that it was informed on April 28 via a teleconference call of the change, which was made because the platform wanted to operate in China. Taiwan Good Rice is to terminate all cooperative relationships with GlobalGiving in response to the platform’s “unilateral and non-negotiable” decision to remove references to Taiwan, the NGO said. “Taiwan is in the official name of Taiwan Good Rice Association and the

Chinese Nationalist Party (KMT) Chairwoman Cheng Li-wun (鄭麗文) yesterday briefed her party’s Central Standing Committee regarding her scheduled visit to the US between Monday next week and June 16, saying that her purpose would be to persuade the US that the Republic of China (ROC) Constitution was a “one China” constitution that would foster stable and peaceful cross-strait relations. The ROC Constitution is the most important defense for all Taiwanese citizens, as it upholds our democracy and has contributed to our robust economy, which aligns with international and US interests, she said. “We would not be troublemakers and drag the US under,”
