Background: Healthcare workers are recommended to provide tuberculosis (TB) patients with tobacco control intervention according to the ABC (ask, brief advice, cessation support) approach in helping TB patients who smoked to quit smoking. In addition, directly observed therapy (DOTS) providers can also play a key role in encouraging smoking cessation. However, there is scarce data on the association between these measures and smoking cessation among TB patients.
Objective: To assess the association between smoking cessation advice and changes in self-reported smoking behaviours among TB patients who were smokers at diagnosis in Indonesia.
Methods: We conducted a hospital-based cross-sectional study of 38 pulmonary TB patients who were current smokers at the time of TB diagnosis. We excluded 4 patients who provided erroneous answers (n=34 patients). We considered patients who had become former smokers after diagnosis to be “quitters”, otherwise we considered them as those who “remained current smokers”. We analyzed data using descriptive statistics and multivariate logistic regression analyses with adjustment for potential confounders.
Results: There were 11 of 34 patients (32.4%) who received complete ABC. The probability of becoming quitters among those who received complete ABC vs. those who received incomplete, or no ABC was 13.3% and 47.4%, respectively (Adjusted OR = 0.12; 95%CI = 0.01 – 1.24). However, receiving smoking cessation advice from DOTS providers was positively associated with becoming quitters (Adjusted OR = 4.77; 95%CI = 0.65 – 34.81).
Conclusions: Receiving complete ABC was negatively associated with smoking cessation, whereas advice from DOTS providers may influence cessation. Our statistical power was low and social desirability of smoking cessation could have influenced the study findings. Relevant programs should also consider these caveats in the interpretation of study findings.
