Participant Flow

Complete national 2006-2014 Medicare data from Part A, B and D (but not C) were obtained from Center for Medicare and Medicaid Services for patients with ICD-9-CM code 494.0 or 494.1 (bronchiectasis without or with acute exacerbation).

From the identified bronchiectasis cohort, we excluded patients with cystic fibrosis, HIV infection, or a history of organ transplant. Such patients are fundamentally different than non-CF bronchiectasis patients who lack these factors with regard to their risk for infection, hospitalization, and many of the outcomes under study in this proposal.

Measure
Inhaled Corticosteroids (ICS)
New use was defined as the first prescription for a minimum 28 day ("chronic") supply of ICS after a clean period of 12 months with no chronic use of either exposure of interest. ICS included ICS alone or in combination with long-acting beta agonists.
Macrolide Monotherapy
New use was defined as the first prescription for a minimum 28 day ("chronic") supply of macrolide monotherapy after a clean period of 12 months with no chronic use of either exposure of interest. Macrolide monotherapy was defined as oral azithromycin or erythromycin and no other chronic prescription within 30 days that could be associated with NTM therapy (ethambutol, a rifamycin, or a fluoroquinolone). Patients who did not start on macrolide monotherapy were excluded.

Inhaled Corticosteroids (ICS)

New use was defined as the first prescription for a minimum 28 day ("chronic") supply of ICS after a clean period of 12 months with no chronic use of either exposure of interest. ICS included ICS alone or in combination with long-acting beta agonists.
Macrolide Monotherapy
n=1736 Patient-years
New use was defined as the first prescription for a minimum 28 day ("chronic") supply of macrolide monotherapy after a clean period of 12 months with no chronic use of either exposure of interest. Macrolide monotherapy was defined as oral azithromycin or erythromycin and no other chronic prescription within 30 days that could be associated with NTM therapy (ethambutol, a rifamycin, or a fluoroquinolone). Patients who did not start on macrolide monotherapy were excluded.
