Several clinical trials have been carried out to evaluate the effectiveness of education programmes and self care in COPD. In the Cochrane revision (up-date 2007), no conclusions could be drawn about the effectiveness of self-control due to the great diversity of variables measured in the few studies published. Based on the antecedents presented, it is evident that COPD is a disease which is difficult to control in daily clinical practice, and that this inadequate control has a significant impact not only on the health of the patient who has this disease, but also on society and the economy.
