Abstract
Introduction: The diagnosis of pulmonary tuberculosis under Revised National Tuberculosis Control Program (RNTCP) is primarily based on sputum examination, in accordance with the guidelines of World Health Organisation. All chest symptomatics are required to get two specimens of sputum examined for establishing the diagnosis at Microscopy Centre. Aim: To assess the importance of initial sputum grading as a predictor of treatment outcome of New Sputum Smear Positive Tuberculosis patients in Tuberculosis Unit (TU) Khammam. Material and methods: All the new sputum smear positive patients registered in Khammam TU during the second and third quarters of 2009 were enrolled as study subjects. A total of 413 patients were registered as per the inclusion criteria under six Designated Microscopic Centres (DMCs). The patients under each DMC area were listed. These patients were followed up till the completion of their treatment. Results: Among the enrolled patient’s (413), 1.69% (7) were found to be scanty grading, 20.34% (84) were found to be 1+ grading on sputum examination, 33.66% (139) were found to be 2+ grading on sputum examination and 44.31% (183) were found to be 3+ grading on sputum examination. The cure rate for patients with sputum 3+ grading was 80.33% and the defaulter rate was 4.92%. Cure rate for patients with sputum 1+ grading was 94.05% and the defaulter rate was 4.76%. Conclusion: The norms of RNTCP regarding sputum smear conversion rate during the intensive phase was achieved in Khammam TU.
