In the CHROMED project, an ICT platform developed in a previously funded FP7 project (i.e. CHRONIOUS project) was adapted and used in combination with measurement devices and methods to monitor patients at home patients with COPD in combination with cardiac comorbidites. Due to the multidimensional nature of the diseases involved, the CHROMED monitoring system was designed as a complex modular multi-device architecture, composed by:

 

 

  • Patient monitoring platform. A touch screen pc (Home Patient Monitor – HPM) represented the data collecting unit placed in the patient’s home. Its functions were the following: 1) to share the 3G connectivity with the other devices assuming a gateway function, 2) to maintain a daily relation with the patient offering questionnaires and reminders for its daily prescribed activities, and 3) to allow remote connection to patient devices for support purposes. Information on patient’s symptoms was collected through the completion of questionnaires (i.e., COPD, CHF, SRDB, EQ-5D, PHQ-9, MHLF, Cost, User satisfaction, etc.) translated in the local languages displayed daily in the HPM through simplified user interfaces. The system was also equipped with an innovative CE-marked device that implements the FOT for the measurement of lung function noninvasively (RESMON PRO DIARY) and, depending on the presence of contingent comorbidities, specific devices for the measurement blood pressures, oxygen saturation, body temperature, and 1 lead ECG (Medic4all Wristclinic) or ventilator patterns during home mechanical ventilation (CPAP monitor). A mobile modem allowed an easy access to the Internet for sending the data to a central database.
  • Central server. The data acquired by the HPM were automatically sent, at the end of the daily measurement session, to a central database where specific algorithms run in real time to perform data integrity tests and specific filtering to reduce the generation of false alarms and increase the system accuracy to identify a patient’s worsening. Then the data were processed according to specific clinical algorithms and medical alarms generated and sent to the clinical staff.
  • CHROMED clinician web platform. Data stored in the CHROMED central server and generated alarms were accessed by the Clinical staff in charge of the patient through a specific web interface. This information was then used to program the best treatment according to the patient’s status. In particular, the clinician interface itself offered to the user the following functions:
    • alarms visualization and operation, that enables medical staff to quickly have an outline of the currently open alarms in the CHROMED system
    • medical data visualization, that enables medical staff to view all the available medical measures and information on per-patient basis.
    • patient recruitment and operation, that enables pilots to automatically randomize the involved patients.
