Knowledge of pediatricians in Rio de Janeiro, Brazil, about inhalation therapy in asthmatic children.
BACKGROUND
Despite the numerous guidelines on the diagnosis and treatment of asthma, there are data that indicate that general pediatrician's knowledge of the disease and its preferred treatment is limited, which may influence the quality of care given to asthmatic children. The purpose of this study was to describe pediatrician's knowledge of spacers and of concepts of chilhood asthma, as well as their prescribing habits concerning inhalation therapy, in the public health system of the city of Rio de Janeiro.


RESULTS
A descriptive cross-sectional study was performed in a sample of 72 pediatricians from the public health system of Rio de Janeiro. A questionnaire was used to assess prescriptions for spacers, the reasons whay spacers were not used, the models employed, classification of asthma according to clinical severity and symptom frequency, recommendation for the correct spacer volume according to age group, and the concept of asthma as an inflammatory disease. Seventy percent (51/72) of the physicians did not routinely prescribe the spacer. The reasons given were as follows: a) lack of spacer availability in the public health system in 55 % (28/51); b) high cost in 57 % (29/51); c) the complexity of their use in 35 % (18/51); d) unwillingness to use aerosol type medication in 15 % (8/51), and e)lack of knowledge of their function and utilization in 59 % (30/51). Of the 30 % (21/72) who reported they regularly and routinely prescribed the spacer in daily practice, 48 % (10/21) stated that this routine prescription, even when indicated, was below 25 % of what was expected and makeshift models were preferred by 24 % (5/21) of the pediatricians. Six percent of the pediatricians chose the appropriate spacer volume according to age group, 62.5 % (45/72) reported that they classified asthma according to severity, 16 % (7/45) gave the correct answers when classifying asthma according to national consensus, and 22 % (16/72) considered asthma to be an inflammatory disease.


CONCLUSIONS
The results of this study suggest that pediatrician's knowledge of inhalation therapy with dosed aerosol spacers and of asthma-related concepts in the public health system in Rio de Janeiro is limited. This may restrict the quality of care given to the asthmatic children in the city and suggests the need for training programs for the management of asthmatic children.
