International guidelines and educational experiences in an out-patient clinic for asthma

Abstract

In June 1989, an out-patient clinic for asthma was instituted at Crema Hospital, Italy. Up to November 1994, 430 adult asthmatics were recruited, classified and managed according to the recommendations of the international guidelines. The aims of this study are to verify: 1) whether the organization of the clinic could maintain asthma under control and reduce hospital admissions; and 2) whether the traditional educational approach could be implemented by lessons in the school of asthma to improve the control of asthma symptoms and/or admissions. The data reported refer to the first 360 asthmatics attending the clinic between 1989 and 1994: 53, 45 and 2% of them were suffering from extrinsic, intrinsic and occupational asthma, respectively. On recruitment, forced expiratory volume in one second (FEV1) was < 80% of predicted in 170 patients, and arterial oxygen tension (Pa,O2) 8.0 kPa (< 60 mmHg) in 27 patients. After the admission visit, 190 patients (53%) were classified as mild, 97 (27%) as moderate, and 73 (20%) as severe asthmatics. In May 1993, a school of asthma was organized. Forty four patients were recruited, stratified according to the severity of their asthma and randomized into two groups: 22 patients attended the school, and 22 patients did not. Each group consisted of 5, 10 and 7 patients with mild, moderate and severe asthma, respectively. The school comprised four lessons twice a week. One year after the end of the school, we could find no differences between the two groups (school versus controls) with regard to the number of urgent care visits (9 vs 9), scheduled visits (22 vs 21) and hospital admissions (2 vs 2).
