Methods: Cross-sectional study in adults with respiratory symptoms (for more than 2 weeks) in the community.
Results: 298 patients were included. The sputum smear was positive in 5.3 % vs. 7.4% with Xpert. The sensitivity of smear and Xpert vs. culture was 53% vs 75%, specificity 93% vs 95%, positive predictive value 37.5% vs 36.4 % and negative predictive value. 98.5% vs 97%, respectively.
Conclusion: In our study XpertMTB / RIF showed better performance than sputum smear in suspected TB cases in the community. Replacing smear microscopy with Xpert MTB/RIF could increase confirmation of pulmonary TB with an additional benefit of rifampicin resistance detection.
