The CHROMED (Clinical trials for elderly patients with multiple diseases) project was designed to evaluate the health and economic impact of using a telemedicine-based model of care on elderly people with a combination of COPD and other comorbidities, such as Chronic Heart Failure (CHF) and Sleep Disordered Breathing (SBD).

An international multi-centric randomized control trial (RCT) was conducted on 312 patients followed up for 9 months in five European countries: United Kingdom, Sweden, Estonia, Spain and Slovenia, representing different social and organizational contexts in Europe. The CHROMED system is based on the analysis of the time series of physiological parameters that are measured by the patient on himself thanks to a set of devices that are installed at his/her home combined with an ICT platform used to collect and process clinical data. Time series of the measured parameters were automatically analyzed by specific algorithms and triggered  cardiac or respiratory alerts that were sent to the clinical center taking care of the patient. Each medical alarm was followed by a nurse phone call to evaluate the patient status and in case of a confirmed worsening, plan a therapeutic action.
