RESUMEN
The purpose of the ASES study is to determine the clinical characteristics of Spanish asthmatic patients seen in primary care (PC) and in pneumology (P) departments, comparing the availability of diagnostic methods, morbidity, the type of treatment and follow-up between the two health care settings. ASES is a multicenter, descriptive, cross-sectional study. The physicians were selected by random sampling. The data were collected by the participating physicians using three questionnaires. Data were collected on 2349 asthmatic patients (1298 from hospitals and 1051 from PC). Smokers predominated in the PC setting (P = 0.000). The spirometry was performed at least once a year in 87.2% of the patients seen in P and 39.8% in PC (P = 0.000). Morbidity was high in both groups (P and PC), more than two nighttime awakenings per month (25.5% versus 29%) and emergency visits in previous year (26% versus 21%). A high percent of asthmatic patients was using both inhaled corticoids and long-acting beta2-agonists (49.5% versus 32%). The 30% of PC patients could not be classified into any step of the treatment. In Spain, the morbidity of disease is high, despite the large use of drugs. Objective monitoring tests have very limited use in PC.
