| − | ==Introduction==
| |
| − | Autoimmune idiopathic inflammatory myopathies (IIMs) have the following common characteristics: Auto-immune disorder, no known cause, muscle inflammation, and muscle weakness and consist of three types: polymyositis, dermatomyositis, and sporadic inclusion body myositis. Many studies have not examined IIM, however using data gathered from commercial insurance, Medicaid and Medicare, this study examined how common and frequent IIM is.

| − | ==Methods==
| |
| − | Data from 2004 - 2008 was gathered from:
| |
| − | # 130 unique commercial insurance companies for outpatient pharmacy claims for people under 65 (14 million enrollees annually)
| |
| − | # Medicare supplemental insurance paid for by employers for retired and working-age recipients (1.6 million individuals)
| |
| − | # Pooled Medicaid healthcare information from 10 states (28 million)
| |
| − | The data was filtered for patients over the age of 18 with an IIM treatment and patients who had a muscle biopsy; incidence and prevalence was then calculated.

| − | ==Results==
| |
| − | The study identified 2,990 incident cases with 2,477 (83%) were from the commercially insured/Medicare supplemental databases and 513 (17%) were from the Medicaid database with 1,072 had dermatomyositis, 1,784 had polymyositis, and .476 had interstitial myositis. The study also identified 7,155 prevalent patients 39.1% had dermatomyositis, 58.9% had polymyositis, and 9.8% had interstitial myositis.
