Tobacco Cessation Clinical Trial
Official title:
Randomized Clinical Trial About the Effectiveness of the Spirometry Test as a Motivational Tool for Quitting Tobacco in Primary Care
The purpose of this study is analyze if spirometry is a motivational element for changes in the cessation phases of the tobacco habit, compared with not done spirometry.
According to data from the last INE health survey carried out in 2006, 31.4% of males and
22.3 % of females smoked, in other words more than 26% of the population were smokers. In the
Region of Murcia, according to the same Health Survey, the data are even higher than those of
Spain, with figures for male smokers at 36.25% and 23.31% for women, with an overall
prevalence rate of nearly 30%.
In light of these data, it is necessary to carry out intervention to help tobacco cessation
and in this regard,the 98% of smokers trying to quit on their own without any specific
support do not achieve their goal.
Interventions at Primary Care Consultations we have two useful tools at our disposal: One of
these is brief advice It should be firm, understandable, individualized, verbal and direct.
It should last between 3 and 5 minutes and be eminently positive, highlighting the advantages
of becoming an ex-smoker. This intervention vs non intervention have an OR=1.69 (IC
95%1.45-1.98). The other intervention we have in an intensive. This includes providing
systematic anti-tobacco advice accompanied by written documentation and psychological support
as well as the follow-up of patients in their dishabituation process, with a periodicity
which varies according to different studies, although to do this more time will have to be
dedicated in the consultation.
As more intense intervention on these patients as efficacy obtained is higher, increasing
abstinence rates significantly.
Appropriate interventions based on stage of change are based on the transtheoretical model of
Prochaska and DiClemente. Smokers are at one stage or another in terms of lesser or greater
degree of motivation to quit being closely related to the phases of abandonment of tobacco.
In addition to these tools, two other interventions have been studied which could be useful
for increasing cessation rates. In this regard, a Cochrane review determined the efficiency
of the evaluation of biomedical risks and different levels of assessment used as a cessation
tool for quitting the tobacco habit. The information from eleven trials was analyzed and in
three of them spirometry and co-oximetry were used as motivational elements for tobacco
cessation. However, the results were inconclusive due to the heterogeneity of the studies,
but concludes that it is possible to further improve the methodological quality of studies
aimed at evaluating the effectiveness of biomedical risk assessment, including spirometry, as
an aid to quit smoking. Other studies also seen as a considerable number of smokers get
smoking quit after learning their spirometric results.
For all of these reasons, it is necessary to carry out interventions which help to encourage
tobacco habit cessation and in this regard this study has been designed, in which it is
intended to assess spirometry , as a motivational element in the phase of tobacco cessation.
