The fundamental etiologic factor of COPD is tobacco. This has a 9% prevalence in Spain and although this rate is underestimated according to the last studies, COPD generates about 39,000 hospital admissions per year. It has a re-admission rate between 12% and 32%, infections being the fundamental cause. The average care cost per patient from its diagnostic to death is 27,500 euro and we should add a high percentage of employee absenteeism. Due to its chronic aspect, high health care cost and possible improvement of the quality of life of patient, the solution to the problem needs to have a more active involvement of the doctor who attends these patients.
