Home Non-Invasive Ventilation in COPD: A Global Systematic Review

Area of Science:

• Pulmonary Medicine
• Respiratory Care

Background:

• Uncertainty exists regarding the benefits of home non-invasive ventilation (NIV) for stable chronic obstructive pulmonary disease (COPD) patients.
• The impact of NIV on patients with recent exacerbations (post-hospital) also requires further investigation.

Purpose of the Study:

• To update the evidence base on home NIV for COPD patients, including studies in any language.
• To explore the impact of newly available studies on the overall evidence for NIV's effectiveness.

Main Methods:

• Systematic review methodology including randomized controlled trials (RCTs) and non-randomized studies.
• Random effects meta-analysis for mortality and hospitalizations, with subgroup analyses by population and study design.
• Inclusion of studies from various countries, including Chinese language publications.

Main Results:

• A total of 103 studies were included, significantly expanding the evidence base.
• No significant effect on mortality was observed in stable COPD patients.
• A reduction in hospital admissions (1-2 per year) was noted across subgroups, with greater reductions in length of stay reported in Chinese studies.

Conclusions:

• The evidence base for home NIV in COPD is now considerably larger.
• NIV shows potential for reducing hospital admissions and improving quality of life, but mortality benefits are not consistently demonstrated.
• Individual participant data analysis is recommended to identify patient subgroups most likely to benefit from NIV.
