: Three-year Mortality Following Prescription of Multidrug Antibiotic Treatment for Pulmonary Disease in United States Medicare Beneficiaries With Bronchiectasis. | LitMetric

AI Article Synopsis

  • * Results showed that patients on guideline-based therapy (GBT) had lower mortality rates compared to those on non-guideline therapies (non-GBT), with significant findings for both 2007 and 2020 GBT regimens.
  • * No significant difference in 3-year mortality was found between patients on 3-drug and 2-drug regimens, indicating the need for further research on the effectiveness of different treatments.

Article Abstract

Background/aims: Although increased mortality has been reported among people with pulmonary disease (MAC-PD), data are limited on survival associated with various antibiotic regimens used to treat MAC-PD. We conducted a comparative analysis of 3-year mortality in Medicare beneficiaries with bronchiectasis using various MAC-PD regimens.

Methods: We included Medicare beneficiaries aged ≥65 years with bronchiectasis (01/2006-12/2014). We limited our cohort to new MAC-PD therapy users. MAC-PD therapy was defined as ≥60-day prescriptions for a macrolide plus ≥1 other MAC-PD antibiotic. Guideline-based therapy (GBT) included a macrolide, ethambutol, and/or rifamycin. Using Cox proportional hazard models, we calculated adjusted hazard ratios (aHR) for death up to 3 years after therapy start between the following groups: (1) 2007 GBT versus non-GBT; (2) 2020 GBT versus non-GBT; and (3) macrolide-ethambutol-rifamycin (3-drug) versus macrolide-ethambutol (2-drug).

Results: We identified 4820 new MAC-PD therapy users, of whom 866 (17.9%) were deceased within 3 years of therapy initiation. Of 3040 (63.1%) beneficiaries prescribed 2007 GBT, 472 (15.5%) were deceased by 3 years, compared to 394 (22.1%) of 1780 (36.9%) prescribed non-GBT (aHR 0.82; 95% confidence interval [CI], .72-.94). We observed a similar trend for 2020 GBT versus non-GBT (aHR 0.81; 95% CI, .70-.94]). Three-year-mortality was similar between those starting 3-drug versus 2-drug regimens (aHR 0.89; 95% CI, .74-1.08]).

Conclusions: Among Medicare new MAC-PD therapy users, 3-year-mortality was higher in those prescribed non-GBT regimens compared to GBT regimens. Whether this finding suggests improved efficacy of GBT and/or differential characteristic of those using non-GBT regimens deserves further study.
