Sociodemographic and clinical risk factors associated with in-hospital tuberculosis mortality in Türkiye, 2008-2018

Sociodemographic and clinical risk factors associated with in-hospital tuberculosis mortality in Türkiye, 2008-2018Introduction: Tuberculosis (TB) is an infectious disease that can be fatal if left untreated or poorly treated, and it is associated with many morbidities.Deaths may provide better understanding of the associated factors and help guide interventions to reduce mortality.In this study, it was aimed to reveal some of the features that predict hospital mortality in patients with TB and to present some alarming findings for clinicians. Materials and Methods:Patients who had been hospitalized with the diagnosis of TB between January 2008 and December 2018 were included and analyzed retrospectively.In-hospital mortality because of any TB disease after the initiation of treatment in patients admitted to the TB Ward and the primary cause of mortality were taken as endpoint.Results: A total of 1321 patients with a mean age of 50.1 years were examined.Total mortality was 39.4% (521 deaths) and 13.1% were in-hospital deaths (173 deaths).Of the deaths, 61.8% (n= 107) occurred during the first month after TB treatment were started.On univariate analysis, age over 48.5 years, Charlson comorbidity index, extension of radiological involvement, hypoalbuminemia and lymphopenia were most predictive variables with higher odds ratios (respectively, p< 0.001 for all). Conclusion:In-hospital tuberculosis disease mortality is related with older age, cavitary or extensive pulmonary involvement, low albumin levels, unemployment, cigarette smoking and especially those with concomitant malignancy and chronic pulmonary disease.
