Proyecto Madrileño Sobre el Manejo de la Enfermedad Pulmonar Obstructiva Crónica Con Telemonitorización a Domicilio. (Multicentre Project on the Home Telemonitoring of Patients With Severe Chronic Obstructive Pulmonary Disease).

Randomized, controlled, multicenter, performance, cost assessment and economic evaluation clinical trial. An arm of the trial will consist of patients assigned to the intervention group (telehealth group: TG ), and the other arm will consist of patients randomized to the control group (routine clinical practice: RCP).

For the economic evaluation, the perspective of the health system will be used. Therefore it only direct costs will be considered. In the TG arm also intervention costs it will be considered.

Patient selection:

Responsible researcher at each hospital center will coordinate the patient selection process. The researchers will identify candidate patients screening through hospital medical records.

After this first screening, patients will be contacted and invited to participate in the study. In a personal interview, the researcher explains the study to the patient and deliver the information sheet, verifying that patient meets all inclusion/exclusion criteria, obtains informed consent and then proceeds to patient randomization. To avoid bias from exclusions, researchers will hold record with patient exclusion causes.
