Telemonitoring systems, by which the symptoms of heart failure can be remotely assessed, now provide a strategy for the improved personalised care of patients, according to Professor John Cleland from the University of Hull, UK.1 He told Heart Failure Congress 2009 that the management of heart failure is complex but most effective when tailored to the individual patients' needs and condition.2 "Unfortunately," he added, "the resources required to offer this tailored treatment outside a hospital setting are generally not available. Current services provide, at best, only a crude attempt to deliver long-term, personalised healthcare, but telemonitoring provides a strategy which could radically change this situation."
Professor Cleland explained that the first generation of home monitoring devices for heart failure were relatively simple. They were designed to measure symptoms, weight, heart rate and rhythm, and blood pressure. But, he said, "from the patient's perspective, they were relatively unrewarding since the systems provide little in the way of advice or feedback. Nonetheless, a series of randomised controlled trials have shown a reduction in mortality and in days spent in hospital, although not in the rate of hospitalisation."
Ongoing trials of second generation equipment, he continued, reflect the same measure of symptom assessment but a more interactive experience for the patient. "These newer systems," he explained, "provide education, feedback to patients on their results, treatment and appointment reminders and a limited amount of advice on adjusting therapy. They are likely to deliver even greater health gains than first generation systems."
And now, further generations of telemonitoring systems are being developed, including:
