Citation: Alqahtani JS, Oyelade T, Aldhahir AM, et al. Prevalence, severity and mortality associated with COPD and smoking in patients with COVID-19: a rapid systematic review and meta-analysis. PLoS One. 2020 May 11;15(5):e0233147.
What is this? Patients with respiratory conditions, such as chronic obstructive pulmonary disease (COPD), and smokers may be at higher risk of complications of COVID-19 infection.
In this rapid review, the authors searched for studies on prevalence, severity and mortality associated with COPD and smoking in patients with COVID-19. They restricted their searches to articles published in English and did the search on 24 March 2020. They included 15 retrospective studies (total: 2473 COVID-19 patients), which were from China (14 studies) and the USA (1).
What was found: At the time of the review, the included studies showed that the prevalence of COPD in COVID-19 patients was low, but COPD patients had more severe COVID-19 disease and a higher mortality rate than those without COPD.
At the time of the review, the included studies showed that current smokers had more severe COVID-19 disease and a higher mortality rate than former and never smokers.
