End-of-Life Strategies among Patients with Advanced Chronic Obstructive Pulmonary Disease.
The burden of advanced chronic obstructive pulmonary disease (COPD) is high globally; however, little is known about how often end-of-life strategies are used by this population. ⋯ The proportion of people with advanced COPD using end-of-life strategies, although increasing, remains low. Efforts should focus on increasing access to such strategies and educating patients and providers of their benefits.

Observational StudyLongitudinal Phenotypes and Mortality in Preserved Ratio Impaired Spirometry in the COPDGene Study.
Increasing awareness of the prevalence and significance of Preserved Ratio Impaired Spirometry (PRISm), alternatively known as restrictive or Global Initiative for Chronic Obstructive Lung Disease (GOLD)-unclassified spirometry, has expanded the body of knowledge on cross-sectional risk factors. However, longitudinal studies of PRISm remain limited. ⋯ PRISm is highly prevalent, is associated with increased mortality, and represents a transitional state for significant subgroups of subjects. Additional studies to characterize longitudinal progression in PRISm are warranted.
