Global trends in systemic sclerosis-related mortality, 2001–2023: an epidemiological analysis using World Health Organization mortality data

Category	Detail
Condition	Systemic sclerosis (SSc), a rare autoimmune connective tissue disease characterized by fibrosis and vascular abnormalities.
Key Mechanisms	Autoimmune-mediated fibrosis affecting skin and internal organs including lungs, kidneys, and gastrointestinal tract; involvement of vascular dysfunction and immune dysregulation.
Target Population	Predominantly affects women (~80% of cases), with incidence increasing with age; global prevalence approximately 18.87 per 100,000 persons.
Care Setting	Specialized rheumatology and multidisciplinary care centers managing autoimmune and connective tissue diseases.

SSc ranks highest in mortality among rheumatic diseases globally, with 85,291 deaths reported from 2001 to 2023 across 74 countries.
Mortality rates increase with age, peaking in the 80–84 year age group, and predominantly affect women (79.4% of deaths).
Leading causes of SSc mortality are other forms of SSc (M34.8) and unspecified SSc (M34.9), highlighting heterogeneity in disease manifestations.

Use ICD-10 codes M34 and subcategories (M34.0, M34.1, M34.2, M34.8, M34.9) to identify systemic sclerosis in mortality and clinical data.
Assess clinical domains including Raynaud’s phenomenon, digital ulcers, pulmonary arterial hypertension, renal crisis, skin fibrosis, interstitial lung disease, gastrointestinal and musculoskeletal involvement.

Multidisciplinary management targeting organ-specific complications to reduce morbidity and mortality.
Early identification and treatment of pulmonary arterial hypertension and interstitial lung disease to improve survival.
Monitor and manage scleroderma renal crisis promptly.

Regular assessment of organ involvement and disease progression, especially in high-risk populations (older age, female sex).
Utilize epidemiological data to identify trends and high-risk regions for targeted interventions.

Patients diagnosed with systemic sclerosis, predominantly women and older adults.

Data emphasize the need for tailored therapies addressing diverse organ involvement and early intervention to reduce mortality.

Incorporate comprehensive ICD-10 coding for accurate diagnosis and mortality tracking of SSc subtypes.
Focus on early detection and management of pulmonary and renal complications to improve survival.
Use population-based mortality data to guide public health strategies and resource allocation.
Ensure multidisciplinary care involving rheumatologists, pulmonologists, nephrologists, and other specialists.
Prioritize patient education on disease manifestations and importance of regular monitoring.
