A doctor who suffers from asthma has come up with the potentially useful idea of using cell phones to link patients to hospitals. In this way, he says, patients' can have their health remotely monitored and receive timely medical advice.
Kuo Han-pin (
Kuo said he conducted an experiment in which he asked more than 100 asthma patients to record their peak expiratory flow rate each morning and evening. He found that most of them did not take the trouble to do the job properly, but just perfunctorily jotted down some figures. This, he realized, hampers doctors' ability to properly monitor their patients.
Chang Gung Hospital even designed a Web site and a CD-ROM-based program for patients to register their PEFR numbers online, but to no avail, Kuo said.
Kuo therefore came up with the idea of cooperating with cell phone carriers such as Chung Hwa Telecom to install a special program on patients' cell phones that could save and transmit PEFR and other basic health data to hospitals, whose automatic response system would analyze and return medical advice to the patients via text messages.
For example, Kuo said, seasonal weather changes in early spring can induce severe asthmatic symptoms that can be worsened by sandstorms sweeping down from China. If patients regularly send their PEFR numbers to the hospital system, they could receive medical advice and reminders either by text messages or voice calls.
If telecommunication and Internet technologies could be used to monitor patients' health indicators by remote control, it could create a beneficial situation for hospitals, patients and the health insurance program, Kuo said.
Tropical Storm Nari is not a threat to Taiwan, based on its positioning and trajectory, the Central Weather Administration (CWA) said yesterday. Nari has strengthened from a tropical depression that was positioned south of Japan, it said. The eye of the storm is about 2,100km east of Taipei, with a north-northeast trajectory moving toward the eastern seaboard of Japan, CWA data showed. Based on its current path, the storm would not affect Taiwan, the agency said.
The Taipei Department of Health’s latest inspection of fresh fruit and vegetables sold in local markets revealed a 25 percent failure rate, with most contraventions involving excessive pesticide residues, while two durians were also found to contain heavy metal cadmium at levels exceeding safety limits. Health Food and Drug Division Director Lin Kuan-chen (林冠蓁) yesterday said the agency routinely conducts inspections of fresh produce sold at traditional markets, supermarkets, hypermarkets, retail outlets and restaurants, testing for pesticide residues and other harmful substances. In its most recent inspection, conducted in May, the department randomly collected 52 samples from various locations, with testing showing
The government should improve children’s outdoor spaces and accelerate carbon reduction programs, as the risk of heat-related injury due to high summer temperatures rises each year, Greenpeace told a news conference yesterday. Greenpeace examined summer temperatures in Taipei, New Taipei City, Taoyuan, Hsinchu City, Taichung, Tainan and Kaohsiung to determine the effects of high temperatures and climate change on children’s outdoor activities, citing data garnered by China Medical University, which defines a wet-bulb globe temperature (WBGT) of 29°C or higher as posing the risk of heat-related injury. According to the Central Weather Administration, WBGT, commonly referred to as the heat index, estimates
Taipei and other northern cities are to host air-raid drills from 1:30pm to 2pm tomorrow as part of urban resilience drills held alongside the Han Kuang exercises, Taiwan’s largest annual military exercises. Taipei, New Taipei City, Keelung, Taoyuan, Yilan County, Hsinchu City and Hsinchu County are to hold the annual Wanan air defense exercise tomorrow, following similar drills held in central and southern Taiwan yesterday and today respectively. The Taipei Mass Rapid Transit (MRT) and Maokong Gondola are to run as usual, although stations and passenger parking lots would have an “entry only, no exit” policy once air raid sirens sound, Taipei
