Understanding the Burden of Pyoderma Gangrenosum

of patients with PG died within one year of claims-based PG identification.*
Crude all-cause mortality; incident PG cohort, N=1,663.of patients were hospitalized for any cause within one year of claims-based PG identification.*
One-year post-index subset, n=1,158.of patients were diagnosed with a serious infection within one year of claims-based PG identification.*
Same post-index subset, n=1,158. Relationship to PG or treatment is uncertain.These findings are from a retrospective, claims-based cohort study using Optum Clinformatics® Data Mart. They describe observed outcomes and do not establish that PG or its treatment caused them.
*Identification date was defined as the third unique PG claim within 365 days following a PG-free period of at least 365 days. One year after claims-based identification may be up to two years after the first PG diagnosis code.
