Impact of Smoking and Deprivation in Patients Admitted With Severe COVID‐19 Infection to ICU: A Retrospective Cohort Study

Despite 6.3% prevalence of smoking in patients with severe COVID-19 in the ICU, smokers had increased hospital and ICU LOS with reduced survival. The relationship between COVID-19 and deprivation is multifaceted and complex and may relate to demographic, socioeconomic and environmental factors; health-related risk factors; and practices. From our data we can see that current smokers admitted to ICU with severe COVID-19 were from the most deprived areas in Wales, with a higher mortality risk.
