Epidemiology of Systemic Sclerosis in a Large US Managed Care Population
The Journal of Rheumatology, 03/02/2012
Furst DE et al. – This analysis suggests a higher incidence and lower prevalence of systemic sclerosis (SSc) in this managed care organization (MCO) than those previously reported for the United States.
Subjects with claims–based evidence of SSc (ICD–9–CM code 710.1x) were identified from a health plan database.
Incidence and prevalence for the period 2003–2008 were calculated.
The overall age– and sex–adjusted incidence rate (2003–2008) for SSc was 5.6 cases per 100,000 person–years.
The annual prevalence of SSc ranged from 13.5 in 2003 to 18.4 (per 100,000) in 2008.
