Background: Tuberculosis is a chronic infectious pathology whose incidence is high in developing countries, however, information and studies that analyze mortality and long-term survival are limited. Methodology: retrospective cohort study, in patients with a diagnosis of tuberculosis older than 18 years, admission was consecutive until completing the study period. Survival and mortality were analyzed using the Kaplan-Meier estimator by the log Rank test. Results: 329 subjects were admitted, mortality at 30 days was 11.9% and at one year 24.6%, pulmonary tuberculosis was the most frequent type with 70.2%. Physical examination findings related to mortality were cachexia (p<0.001) and extremity edema (p<0.001). Overall survival was 87.2% at 30 days and 72.9% at one year. In patients with pulmonary tuberculosis, survival was 85.8% at 30 days and 72.8% at one year. Conclusion: The one-year survival rate in patients hospitalized for tuberculosis is low, advanced age, malnutrition, PaO2/FiO2 less than 300, c-reactive protein greater than 45 mg/dL, cerebrovascular disease and peripheral vascular disease were variables that were associated with higher mortality
