 One of the most cost effective intervention is to avoid unnecessary hospitalizations in the national health system. These unnecessary admissions are increasing for several years, reaching rates of over 30 in patients with chronic obstructive pulmonary disease COPD or heart failure at two months of hospital discharge. There is scientific evidence suggesting that a multidisciplinary intervention consisting in controling disease and stress associated with disease, and modifying eating habits could reduce the number of hospitalizations due to disease decompensation.
