ABSTRACT
SUMMARY

OBJECTIVE:

We aimed to explore the prevalence of smoking rates and comorbidities and evaluate the relationship between them and disease severity and mortality in inpatients with COVID-19.

METHODS:

COVID-19 patients were divided into the following groups clinic group, intensive care unit (ICU) group, survivors, and non-survivors. Non-COVID-19 patients were included as a control group. The groups were compared.

RESULTS:

There was no difference between patients with and without COVID-19 in terms of smoking, asthma, diabetes, dementia, coronary artery disease (CAD), hypertension, chronic renal failure and arrhythmia (p>0.05). Older age (Odds ratio (OR), 1.061; 95% confidence interval (CI) 1.041-1.082; p< 0.0001), chronic obstructive pulmonary disease (COPD) (OR, 2.775; 95% CI 1.128-6.829; p=0.026) and CAD (OR, 2.696; 95% CI 1.216-5.974; p=0.015) were significantly associated with ICU admission. Current smoking (OR, 5.101; 95% CI 2.382-10.927; p<0.0001) and former smoking (OR, 3.789; 95% CI 1.845-7.780; p<0.0001) were risk factors for ICU admission. Older age (OR; 1.082; 95% CI 1.056-1.109; p<0.0001), COPD (OR, 3.213; 95% CI 1.224-8.431; p=0.018), CAD (OR, 6.252; 95% CI 2.171-18.004; p=0.001) and congestive heart failure (CHF) (OR, 5.917; 95% CI 1.069-32.258; p=0.042), were significantly associated with mortality. Current smoking (OR, 13.014; 95% CI 5.058-33.480; p<0.0001) and former smoking (OR, 6.507; 95% CI 2.731-15.501; p<0.0001) were also risk factors for mortality.

CONCLUSION:

Smoking, older age, COPD, and CAD were risk factors for ICU admission and mortality in patients with COVID-19. CHF was not a risk factor for ICU admission; however, it was a risk factor for mortality.
RESUMO
RESUMO

OBJETIVO:

Buscamos explorar as taxas de prevalência de tabagismo e de comorbidades e avaliar a relação entre elas e a severidade e mortalidade da doença em pacientes hospitalizados com COVID-19.

MÉTODOS:

Pacientes com COVID-19 foram divididos nos seguintes grupos grupo clínico, grupo da unidade de terapia intensiva (UTI), grupo de sobreviventes e não-sobreviventes. Pacientes sem COVID-19 foram incluídos em um grupo de controle. Os grupos foram comparados.

RESULTADOS:

Não houve diferença entre os pacientes com e sem COVID-19 em termos de tabagismo, asma, diabetes, demência, doença arterial coronariana (DAC), hipertensão arterial, insuficiência renal crônica e arritmia (p>0,05). Idade mais avançada (odds ratio (OR), 1,061; 95% de intervalo de confiança (IC) 1,041-1,082; p< 0,0001), doença pulmonar obstrutiva crônica (DPOC) (OR, 2,775; 95% IC 1,128-6,829; p=0,026) e DAC (OR, 2,696; 95% IC 1,216-5,974; p=0,015) estavam significativamente associados com a admissão na UTI. O tabagismo atual (OR, 5,101; 95% IC 2,382-10,927; p < 0,0001) e tabagismo prévio (OR, 3,789; 95% IC 1,845-7,780; p< 0,0001) foram fatores de risco para admissão na UTI. Idade mais avançada (OR; 1,082; 95% IC 1,056-1,109;< 0,0001), DPOC (OR, 3,213; 95% IC 1,224-8,431; p=0,018), DAC (OR, 6,252; 95% IC 2,171-18,004; p=0,001) e insuficiência cardíaca congestiva (ICC) (OR, 5,917; 95% IC 1,069-32,258; p=0,042) estavam significativamente associados com mortalidade. O tabagismo atual (OR, 13,014; 95% IC 5,058-33,480; p<0,0001) e o tabagismo prévio (OR, 6,507; 95% IC 2,731-15,501; p<0,0001) também foram fatores de risco para mortalidade.

CONCLUSÃO:

O tabagismo, a idade avançada, DPOC e DAC foram fatores de risco para admissão na UTI e mortalidade em pacientes com COVID-19. ICC não foi um fator de risco para admissão na UTI; no entanto, foi um fator de risco para mortalidade.
