Randomized trial demonstrates improved guideline-based care in low-income asthma and COPD patients, suggesting potential for broader implementation.

The aim is to evaluate the effectiveness of a pulmonary specialist health coach consultation model for low-income patients with asthma and COPD.
Randomized controlled trial over 16 weeks comparing intervention and usual care.
Intervention involved a lay health coach coordinating with a pulmonary specialist to provide recommendations.
Primary outcomes included receipt of guideline-based care and medications; secondary outcomes included quality of life and adherence.
Intervention participants received 1.61-fold more guideline-based care than control (relative ratio; CI: 1.37-1.90).
Intervention patients reported significant improvements in chronic lung disease education and breathing-related quality of life.
Post-hoc analysis showed improved receipt of medications for intervention patients.
