Insights
Patients with Duchenne muscular dystrophy in Brazil
Area of Science:
- Neurology
- Rare Diseases
- Public Health
Background:
- Duchenne muscular dystrophy (DMD) is a progressive neuromuscular disorder.
- Early intervention is crucial for managing DMD.
- Healthcare disparities can limit optimal treatment access for rare diseases.
Purpose of the Study:
- To identify unmet needs and challenges in Duchenne muscular dystrophy care.
- Compare care in Brazil's public vs. private health systems.
Main Methods:
- Cross-sectional observational study using the Delphi method.
- Ten neurologists specialized in DMD participated in consensus surveys.
- Descriptive statistics were used for data analysis.
Main Results:
- Public system diagnostic delay averaged 25 months vs. 10 months privately.
- Public system lacks funding for genetic testing, delays corticosteroid treatment, and offers limited multidisciplinary care.
- Public system patients lost ambulation earlier and had shorter life expectancy (19-20 years vs. 26-27 years).
Conclusions:
- Significant disparities exist in Brazilian Duchenne muscular dystrophy care between public and private systems.
- Worse outcomes observed in the public health system.
- Improved access to genetic testing and early multidisciplinary care is vital for enhancing quality of life and survival.
Abstract:
Duchenne muscular dystrophy is a rare, progressive neuromuscular disorder primarily affecting boys, and it follows a predictable course. Early intervention is essential for effective management, but disparities in the care of patients with rare diseases hinder access to optimal treatment.To identify unmet needs and challenges in the care of patients with Duchenne muscular dystrophy within the Brazilian public health system compared with the private system.A cross-sectional observational study using the Delphi method was conducted with ten neurologists specialized in Duchenne muscular dystrophy. The specialists participated in rounds of surveys to reach consensus on key issues, including diagnosis, treatment, and care. Data was analyzed using descriptive statistics.According to the Delphi panel, the public health system had an average diagnostic delay of 25 months compared with 10 months in the private sector. Although genetic testing is critical, it is not funded by the public health system. Other barriers included delayed corticosteroid treatment, limited access to multidisciplinary care, and insufficient medical devices. Patients in the public health system lost ambulation earlier (11-12 years of age) than those in the private sector (13-14 years of age). Life expectancy was significantly shorter in the public system, averaging 19 to 20 years compared with 26 to 27 years of age in the private sector.There are significant disparities in the care of patients with Duchenne muscular dystrophy within Brazil's public health system, resulting in worse outcomes. Enhancing access to genetic testing and early multidisciplinary care is crucial to improve the quality of life and survival of these patients.

Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
