[Level of knowledge of the technique for using metered-dose inhalers among pediatricians].

A longitudinal open prospective study involving 100 pediatricians from 4 different health institutions was performed. After a written description of inhaler technique was provided and a special questionnaire, physicians were asked to demonstrate the technique using a placebo MDI. Correct use was considered if 10 points were obtained. Thirty pediatricians used MDI in children less than 5 years. The correct written description was observed in 55% (55/100) but 32.7% (18/55) failed to use it properly. Although 45% (45/100) made an incorrect description 25% (25/45) demonstrated a describe previous reports which describe that more than half the physicians ignore the correct steps of inhaler technique. Moreover this lack of information appears to be one of the most important factors which affect self-management of acute and chronic symptoms of asthma in which have contributed to the increased morbidity/mortality of the disease since 1980.
