Tuberculosis is an infective disease caused by Mycobacterium tuberculosis. The Direct Observed Treatment Shortcourse (DOTS) strategy designed by WHO to prevent further complications of tuberculosis incorporates drug direct observers aimed to support the improvement of patients. Goals : This study is aimed to determine the effect of drug direct observers on adult lung TB patients improvement at Puskesmas Dengan Tempat Perawatan (DTP) Ciawi-Tasikmalaya in 2014. Methods : This study is an observational analytical study with a cross-sectional design using secondary data from medical records. A minimal sample total of 102 patients were obtained through consecutive sampling. Samples in this study are adult lung tuberculosis patients who have successfully completed their treatment and have fulfilled inclusion and exclusion criterias. Results : Our results showed that lung TB affects more males than females with a percentage of 52% and 48% respectively. Patients are mostly in productive age range (71,5%), while 28,5% are in the non-productive age range. From 172 samples, TB treatment with drug direct observers is done on 133 patients while 39 patients are treated without observers. Patients with observers have a successful treatment rate of 66,86% and an unsuccessful treatment rate of 10,47%. Total recovery rate of lung TB is 77,9%. The recovery rate is still lower from the government’s target. We found a correlation between recovery and drug direct observers with an RP = 1,77 and a p value of 0,000. Conclusion : There is a correlation between drug direct observers on adult lung TB patients improvement. Total recovery rate from lung TB is 77,9% which is still lower than the government’s target.
