Elderly people to receive monitoring care in the "Hospital Without Walls"

Epping 24 April 2001New Australian technology will achieve that some groups of elderly or chronically ill people may soon be able to stay at home rather than move into a hospital or a nursing home. The "Hospital Without Walls" home telecare project, developed by the Australian Commonwealth Scientific and Industrial Research Organisation (CSIRO), has the potential to alter significantly the way in which certain elderly people and people with chronic health problems are cared for, according to researcher Dr. Robert Gill. In the future, the system will also be applied to areas such as chronic cardiac and respiratory disease and medication monitoring.


The home telecare project was one of the Australian technologies which was on show at Hannover Fair in Germany from April 23 to 28, 2001. "Australia, just like most other Western countries, is faced with rising health costs and hospital systems which cannot expand quickly enough to cope with demand", stated Dr. Gill, CSIRO Telecommunications & Industrial Physics.

Dr. Gill explained that changes in disease patterns, notably a shift to age-related and chronic conditions, are exacerbating this trend, and increasing the fact that numbers of patients are being cared for in their homes. By applying telemedicine techniques it is possible to move some functions of health care out of the hospital environment and doctors' surgeries into the home. "This not only reduces the costs of health care but it also allows individuals to maintain their independence by enabling them to remain in their homes", added Dr. Gill.

"Hospital Without Walls" is being developed in a modular form that permits application in a number of areas. The initial version monitors the vital signs of patients who have visited a hospital casualty department following an unexplained fall. The wireless fall monitoring system functions by having patients wear a small portable device with sensors capable of measuring heart rate and body movement. A personal computer within the home will record data from a number of sensors and upload to a remote assessment centre at regular intervals via the telephone network.

"It is very difficult to diagnose the causes of such falls without a record of vital signs at the time of the fall. This home telecare system will help to identify the possible causes of this type of falls, equally including a number of cardiovascular conditions which can only be diagnosed at the time of the fall", commented Dr. Gill. Visiting health professionals will be able to access complete records of vital signs and add to the patient's records.

Initial clinical trials of the system have begun at Ryde Hospital in Sydney. The principal aims of these trials are to confirm the technical efficacy of the technology, investigate patient and staff acceptance, and to explore the value of gait analysis in patients recovering from a major fall. Research work is also progressing on the wide-area networking aspects of the system, which will permit immediate access by health professionals, including the general practitioners and nurses to the latest patient data, and generate alerts in the case of a medical emergency.
