Smoking cessation
The US Public Health Service clinical practice guideline “Treating
Tobacco Use and Dependence” recommends that smokers use pharmaceutical aid to
quit smoking. However, in a study appearing in Tobacco Control in 2016, no
more than 30% of US smokers who quit long term attributed their success to
using 1 or more of these aids. In addition, several observational studies have
suggested that the effectiveness of pharmaceutical cessation aids used in
community settings is less convincing than the efficacy of these medications
under more optimized conditions in randomized clinical trials (in which they
are administered and used in a more standardized manner and usually are
combined with behavioral counseling). Interpretation of the available
observational evidence is challenging because the use of cessation medicine is
not random. Instead, smokers’ choices regarding cessation methods often are
correlated with characteristics that influence their success in remaining
tobacco-free. The researchers at UCSD used propensity score matching, the statistical method that can overcome this limitation more completely than the
ordinary multivariable methods used in previous studies of this topic.
