The Validity Of Medicare Claims-Based Codes To Identify Nontuberculous Mycobacterial Infection In Patients With Bronchiectasis, Jennifer Ku

OHSU-PSU School of Public Health Annual Conference

Background: Nontuberculous mycobacteria (NTM) is a disease of increasing incidence, causing permanent airway damage leading to destructive pulmonary disease. Medicare claims-based codes have been used to identify NTM infection and to evaluate trends in diagnosis and disease outcomes. However, claims-based codes to identify NTM infection have not been validated.

Methods: We linked patients with a bronchiectasis diagnosis (ICD-9-CM 494.0 or 494.1) excluding cystic fibrosis from the national 2006-2014 Centers for Medicare and Medicaid (Medicare) data to the U.S. Bronchiectasis Research Registry (BRR). The BRR is a national prospective cohort of patients with bronchiectasis, that collects detailed clinical, laboratory, microbiology and …

Preventing Infectious Hematopoietic Necrosis In Salmonid Fish Along The Columbia River Basin, Whitney L. Wright

OHSU-PSU School of Public Health Annual Conference

Infectious hematopoietic necrosis virus (IHNV) is a member of the Rhabdoviridae family and causes infectious hematopoietic necrosis (IHN) disease in many salmonid species during the juvenile or “fry” stage of life. IHNV is endemic to Western North America and occurs in the Columbia River Basin, where Steelhead and Chinook salmon are the most abundant IHNV-vulnerable species. IHNV can cause an epidemic in wild or farmed stocks, killing 90-95 percent of the fish it infects. Transmission is currently understood to occur by direct exposure through the gills, and the virus is shed typically from asymptomatic or clinically ill carrier adults at …
