Remote Intervention Versus Routine Monitoring in COPD Patients With Chronic Hypercapnia Receiving Home Non-invasive Respiratory Support
A Randomized Controlled Trial of Remote Intervention Versus Routine Monitoring in COPD Patients With Chronic Hypercapnia Receiving Home Non-invasive Respiratory Support
調査の概要
状態
詳細な説明
Chronic Obstructive Pulmonary Disease (COPD) is a major cause of morbidity and mortality worldwide. A subset of patients with severe COPD develops chronic hypercapnic respiratory failure, often requiring long-term home non-invasive ventilation (NIV). While NIV can improve gas exchange, optimal management strategies, particularly post-hospitalization, are still being investigated.
This study aims to determine if a proactive, remote management strategy can improve patient outcomes compared to standard care with passive monitoring.
Experimental Group (Remote Intervention): Participants will receive home NIV with remote monitoring. A respiratory therapist will actively review ventilation data, assess oxygenation, and perform remote parameter adjustments and individualized optimization based on pre-set conditions and risk predictions.
Control Group (Monitoring Control): Participants will receive home NIV with remote monitoring. However, the study team will not perform active interventions based on the monitoring data. Patients will continue with their usual care and follow-up with their primary physician. The study team will only make contact in case of a severe safety risk.
The study will enroll 236 participants who will be randomized 1:1 to one of the two groups. The primary outcomes are the change in health-related quality of life and the number of COPD exacerbations over 12 months.

説明
Inclusion Criteria:
- Meets the diagnostic criteria for Chronic Obstructive Pulmonary Disease (COPD) with confirmed persistent airflow limitation by spirometry.
- Hospitalized due to an acute exacerbation of COPD.
- Stable daytime arterial blood gas analysis showing PaCO₂ ≥ 50 mmHg, with hypoxemia.
- Already receiving or planned to receive long-term home non-invasive respiratory support.
- Capable of using a smartphone or tablet for video communication and has internet access.
- Willing to participate and provides written informed consent.
Exclusion Criteria:
- Concurrent severe pulmonary diseases (e.g., active tuberculosis, diffuse pulmonary fibrosis, advanced lung cancer).
- Chronic respiratory failure primarily caused by non-COPD conditions (e.g., neuromuscular disease, chest wall deformity, or severe obesity hypoventilation syndrome).
- Severe cognitive impairment or psychiatric illness that would prevent cooperation with remote management.
- Other severe systemic diseases with an expected survival of less than 1 year (e.g., advanced malignancy).
- Pregnant or lactating women.
