Alcohol, Factors, Risk factors, Smoking


Background: Many factors affect treatment outcome negatively. Study of these factors is essential to prevent relapse and treatment failure. The objective of the research was to study the factors affecting the treatment outcome among TB patients.

Methods: Patients diagnosed to have tuberculosis who are attending the DOTS centre at a tertiary care hospital, and fulfilling the inclusion and exclusion criteria were included in the present study. 50 patients who were being treated under DOTS regime were included in the present study. The study was conducted for a period of two years. The patients were followed for a period of six months to observe the treatment outcome among them.

Results: Maximum patient were in the age group of 21-40 years (50%) followed by 41-60 years (28.3%). Cough was present in 76.7% of the cases and was the most common presenting symptom of the cases. The cure rate was significantly more among non alcoholics compared to alcoholics. The cure rate was only 60% among smokers compared to 88.5% among non smokers. The non cure rate was high among smokers i.e. 40% compared to only 11.5% among those who never smoked. This difference was found to be statistically significant.

Conclusions: Smoking and alcohol were found to be important risk factors for treatment failure in the present study.
