The Whole System Demonstrator trial aimed to test whether new telehealth technologies could help people stay healthy at home. It involved 6000 patients across three sites including Cornwall. The trial provided patients with devices to monitor health readings like blood pressure and weight at home, which were transmitted to nurses. Initial concerns from doctors about increased workload were alleviated as the technology allowed remote monitoring and helped prevent unnecessary visits. Patients found the systems easy to use and that it increased their independence and empowerment.
