Official title

BREATHE 2 Cluster-randomized Trial of Health System Changes to Increase Reach of Smoking Cessation Treatments

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this research study is to see if offering adult primary care patients who smoke combustible cigarettes more frequent outreach, more choices about how they receive that outreach, and more smoking treatment options will increase the use of smoking treatments and help more people quit smoking, when compared against a standard outreach approach. Only patients at participating adult primary care clinics will be eligible for the study. Five clinic sites will be randomized to an enhanced outreach approach, while another 5 will be randomly assigned to standard smoking treatment outreach. Eligible patients at these clinics will be in this study for up to 18 months.
