Long-term non-invasive ventilation in muscular dystrophy

Area of Science:

• Respiratory Medicine
• Neuromuscular Disorders

Background:

• Long-term non-invasive ventilation (NIV) initially served patients with poliomyelitis, muscular dystrophy (MD), and scoliosis.
• Obesity hypoventilation syndrome is now the most common reason for home NIV referrals.
• Patients with MD represent a smaller but significant group requiring specialized, long-term ventilatory support.

Purpose of the Study:

• To analyze trends in home NIV use among patients with muscular dystrophy (MD) over 25 years.
• To assess the demographic and survival characteristics of MD patients on home NIV.
• To inform future service planning for MD patients requiring ventilatory support.

Main Methods:

• Retrospective analysis of patient data from a single NIV unit.
• Examination of referral trends, age at commencement, survival rates, and distance from the unit.
• Data collected over a 25-year period.

Main Results:

• New MD referrals for home NIV have stabilized at approximately 20-25 per 5-year period (0.5 per 100,000 population/year).
• The mean age for starting NIV is 37.5 years.
• 5-year survival is 70-75%, and 10-year survival exceeds 40%.

Conclusions:

• Patients with MD remain a crucial, long-term component of home NIV services.
• Stable referral rates and improved survival necessitate continued service planning for this population.
• The findings provide valuable data for optimizing care delivery for MD patients on NIV.
