Study of factors leading to treatment delay in new sputum positive pulmonary tuberculosis patients and its impact on sputum conversion.

Our study was done to identify patient or health system related delay in diagnosis of treatment naïve sputum positive PTB patients and its impact on sputum conversion at 2 months. A total of 280 patients were enrolled and followed up for 2 months following which repeat sputum examination was done. Detailed clinical history was taken with emphasis on duration of symptoms, day of presentation, diagnosis and starting of therapy. The median(range) of delay in treatment initiation was 15 (0-82) days, most commonly because of delay due to the health system. Patients with positive sputum at the end of two months had significantly higher delay in treatment initiation (p < 0.05). Being remote (>5 km) from a health provider, being an unskilled labourer, and visiting a private practitioner were associated with delay in diagnosis. Eradication of tuberculosis in India requires training of health professionals, intersectoral cooperation and better public outreach.
