Background: Sputum microscopy is still used for diagnosis of drug-sensitive pulmonary tuberculosis (TB). Revised National Tuberculosis Control Program (TB programs) aims to rapidly diagnose and treat all cases of TB. The aim of this study is to find the proportion of loss to follow up during diagnosis of pulmonary TB after the patient reached hospital (was handed over sputum cups for sputum collection) from DOTS center after referral from respective outpatient department (OPD) at a tertiary care hospital. Methodology: Record-based data from designated microscopic center at a tertiary care hospital were collected regarding the number of patients who had been given sputum cup container for sputum collection for diagnosis of pulmonary TB referred from different OPDs from January to December 2015. Results: A total of 1518 presumptive patient for pulmonary TB had visited DOTS center after referral from different OPDs in the hospital for sputum examination during the above period. The loss to follow-up during diagnosis among presumptive pulmonary TB patient was 461 (30.04%), which was higher among those below 15 years of age. At this rate of loss to follow up of presumptive TB patient to submit sputum for diagnosis, it was estimated to be about 46 smear-positive pulmonary TB cases per year which will be missed out for diagnosis during the above period (considering sputum positivity rate is 10% in the hospital). The mean gap between sputum referral to submission of two sputum samples was 2.73 days (95% confidence interval 2.52-2.84) among those of submitted sputum for diagnosis. Conclusion: Approximately one-third of presumptive patient for pulmonary TB had loss to follow-up for diagnosis of TB even after consulting a doctor at a tertiary care hospital. There is a need to address this gap in diagnosis of pulmonary TB in this region.
