Spinal Muscular Atrophy: Epidemiology and Health Burden in Children – A Polish National Healthcare Database Perspective Before Introduction of SMA-Specific Treatment

Spinal muscular atrophy (SMA) is one of the most frequent autosomal recessive neuromuscular disorders. It leads to progressive muscle weakness, premature death or permanent ventilation. Significant disability, scoliosis, severe pulmonary infections and other problems require in- and outpatient medical care. Various approaches have been used to evaluate SMA epidemiology, healthcare burden and adherence to standard of care. The recent introduction of pharmacological treatment in a large SMA population will change the course of the disease and the healthcare requirements of patients.
