MINACAPILLI, Mauricio et al. Prevalence of smoking and its characteristics in patients hospitalized in moderate care at a public university hospital. Rev. Urug. Med. Int. [online]. 2021, vol.6, n.1, pp.24-33.  Epub Mar 01, 2021. ISSN 2393-6797.


Smoking is the main cause of disease and death worldwide, being a frequent comorbidity in hospitalized patients, with longer stays and worse results. At Hospital de Clínicas, there are no studies evaluating the prevalence of smoking in hospitalized users since 2005.


to assess the prevalence of smokers and their characteristics in patients admitted to the moderate care room of a University Hospital.


Observational, analytical, cross-sectional study. Results: 100 patients were included, 38% were smokers, 27% ex-smokers and 35% had no history of smoking. The mean age was 48.65 years among the smokers; 63.11 in former smokers; 58.68 in non-smokers. 44.73% of the smokers reported abstinence and intended to maintain abstinence. The mean hospitalization of the group of smokers was 31.07 days, while among non-smokers it was 20.11 (p = 0.1337). 14% of the study population died during hospitalization. Of this group, 14.28% were not smokers, 28.57% were ex-smokers and 57.14% were smokers (p = 0.0569). The mean age of death in smokers was 49.37 years, in ex-smokers it was 70.75 years and 76 years in non-smokers.

Conclusions and Implications:

high prevalence of smoking in hospitalized patients, with longer hospital stays, and higher mortality at a younger age. Many smokers are highly motivated to quit and would benefit from interdisciplinary teams to address them.
