33 access awareness www.accessmagazine.co.uk L ast issue I looked at the concept of mHealth – using mobile and wireless technologies to make health monitoring and treatment more efficient. This month, I’m examining one aspect of mHealth – telehealth. Telehealth devices allow people with chronic conditions, such as stroke, heart disease, diabetes and chest conditions, to monitor their health in their own homes. Certain types of monitors, meters, weighing scales and other devices enable users to take an active role in the management of their condition, by electronically sending medical observations and data directly to a health practitioner who will be monitoring their condition remotely. The table below gives some examples of telehealth devices and what they do: Data-transmitting telehealth devices are designed to collect data and transmit it in packets (the method used to enable electronic communications across the internet) to designated hospitals and other health facilities. Once the data is received and stored it can be used to assess the person’s condition by medical staff – who might then suggest modifications to the individual’s existing treatment, if required. Some telehealth systems may include Guy Dewsbury presents an overview of telehealth – what it is, and the uses it can be put to… a monitor-equipped ‘telehealth hub’, which can be made to display a series of personalised questions for the user to answer on how they feel and how they are managing their conditions. Other systems might display the questions on a private webpage that can be accessed via a standard web browser. The answers to these questions will be passed to the medical team and used to help them in making their diagnoses. healthcare, in which medical teams can quickly respond to changes in the patient and prevent episodes or further deterioration of their condition. Most importantly, if the devices report an irregular reading, this can be flagged to the health team as requiring urgent attention. Often the patient will be unaware that their health status has changed until the health team contacts them. This form of remote health monitoring means that hospital resources can be freed up. When someone can manage their own health with the support of technology and a specialist health team, it allows the home to, in effect, become a hospital. As technology develops, telehealth devices will become ever more discreet and able to provide health professionals with increasingly sophisticated measurements. TECH TALK Proactive healthcare Telehealth equipment can be used alongside other peripherals, such as oxygen supplies. For people with complex conditions, it may be necessary for them to be provided with multiple telehealth devices. Abnormal readings will alert the support team, who then can contact the patient directly and provide advice on how best to manage their condition. This enables a more proactive approach to Use Measures glucose in the patient’s blood Measures the patient’s blood pressure Enables a patient’s weight to be sent remotely to the health team Measures the amount of oxygen in the patient’s blood Measures the person's maximum speed of expiration (breathing out) Provides specific questions relating to how the person is coping with their condition.
