Distance technologies for patient monitoring

Medical technology once used exclusively in hospitals and general practices is now available for use in the home. A growing selection of innovative electronic monitoring devices is available, but meaningful communication and decision supports are also needed for both patients and clinicians. Several randomised clinical trials of home distance monitoring of glucose concentrations by computer found improved outcomes in diabetes care. Likewise, trials of home distance monitoring of blood pressure show enhanced efficiency. Failure to improve outcomes of high risk pregnancies through home distance monitoring illustrates the difficulties in certain clinical applications. Overall, electronic monitoring at home promises cost effective health services, more active involvement of patients in their own care, and a new sense of realism in making a diagnosis.
