|Abstract||Setting: Public hospital emergency room (ER) in Porto Alegre, Brazil, a setting with high prevalence of tuberculosis (TB) and human immunodeficiency virus (HIV) infection. Objective: To determine the prevalence of PTB, using a symptom based active case finding (ACF) strategy in the ER of a public hospital in an area with high prevalence of TB and HIV, as well as variables associated with pulmonary TB diagnosis. Methods: Cross sectional study. All patients $18 years seeking care at the ER were screened for respiratory symptoms and those with cough $2 weeks were invited to provide a chest radiograph and two unsupervised samples of sputum for acidfast bacilli smear and culture. Results: Among 31,267 admissions, 6,273 (20.1%) reported respiratory symptoms; 197 reported cough $2 weeks, of which pulmonary TB was diagnosed in 30. In multivariate analysis, the variables associated with a pulmonary tuberculosis diagnosis were: age (OR 0.94, 95% CI: 0.92–0.97; p,0.0001), sputum production (OR 0.18, 95% CI 0.06–0.56; p = 0.003), and radiographic findings typical of TB (OR 12.11, 95% CI 4.45–32.93; p,0.0001). Conclusions: This study identified a high prevalence of pulmonary TB among patients who sought care at the emergency department of a tertiary hospital, emphasizing the importance of regular screening of all comers for active TB in this setting.
