Nontuberculous mycobacterial lung disease prevalence at four integrated health care delivery systems.

ABSTRACT:

Rationale

Single-site clinic-based studies suggest an increasing prevalence of pulmonary nontuberculous mycobacteria (NTM) disease, but systematic data are lacking.

Objectives

To describe prevalence and trends for NTM lung disease at four geographically diverse integrated heath care delivery systems in the United States.

Methods

We abstracted mycobacterial culture results from electronic laboratory databases and linked to other datasets containing clinical and demographic information. Possible cases were defined as a single positive NTM pulmonary isolate, and definite cases were defined as two positive sputum cultures, or one positive culture from a bronchoalveolar lavage or lung biopsy. Annual prevalence was calculated using United States census data; average annual
