简要总结
The purpose of this study is to evaluate the effectiveness and clinical efficiency of combining home non-invasive ventilation (NIV) with a continuous remote telemonitoring (TM) system in patients with Chronic Obstructive Pulmonary Disease (COPD) and persistent hypercapnia. In standard practice, patients with severe COPD and high carbon dioxide levels in their blood are treated with home non-invasive ventilation to support their breathing. This study compares two different care strategies over a one-year follow-up period:
- One group of patients will receive standard home non-invasive ventilation alone.
- Another group will receive home non-invasive ventilation combined with an automated telemonitoring system that tracks device parameters daily (such as air leaks, device usage, and breathing rates) and sends automated alerts to the healthcare team if deviations occur. The main goal of the project is to determine if adding a telemonitoring follow-up system can prevent clinical worsenings and significantly reduce the total number of days patients spend hospitalized due to severe COPD flare-ups. Additionally, the study will analyze the impact of both strategies on patients' overall health-related quality of life and the economic costs within the healthcare system.
详细描述
Background and Rationale:
Chronic Obstructive Pulmonary Disease (COPD) with persistent hypercapnia is associated with increased mortality, functional decline, and high healthcare costs. While home non-invasive ventilation (NIV) is established as standard care to correct chronic respiratory failure, integrating remote telemonitoring (TM) presents an opportunity to implement early clinical interventions by allowing continuous oversight of ventilator parameters.
Study Design and Setting:
This is a prospective, multicenter, comparative cohort study with an integrated economic and utility evaluation. The study will be conducted across 5 public university hospitals within the Community of Madrid, Spain. A total of 92 patients (46 patients in the NIV+TM cohort and 46 in the conventional NIV cohort).

结局指标
主要结局
Number of prevented days of hospitalization due to COPD acute exacerbations
时间窗: 12 months
The total number of days a patient spends hospitalized in a general hospital ward or Intensive Care Unit (ICU) due to acute exacerbations of Chronic Obstructive Pulmonary Disease (COPD). An acute exacerbation is defined according to GOLD criteria as an increase in dyspnea, cough, and/or sputum worsening in less than 14 days.
