They also experienced higher rates of depression and stress compared to never-smokers and demonstrated a worse compliance with imposed quarantine rules. We suggest the creation of holistic smoking cessation centers that include depression and stress management of HCWs in order to achieve smoke-free hospitals worldwide and support HCWs' psychological burdenFootnotesCite this article as: European Respiratory Journal 2021; 58: Suppl. 65, PA3200.This abstract was presented at the 2021 ERS International Congress, in session “Prediction of exacerbations in patients with COPD”.This is an ERS International Congress abstract.
