Factors associated with the appropriate use of asthma drugs
Abstract
Background: When used properly, asthma drugs can reduce asthma-related morbidity and mortality.
Objective: To assess the use of asthma drugs, and to identify factors associated with appropriateness of use among patients 12 to 45 years of age.
Methods: Asthmatic patients were interviewed about their asthma drug(s) use and the factors potentially associated with appropriateness of use according to the 2003 Canadian Asthma Consensus Conference guidelines. To determine the factors associated with the appropriate use of asthma drugs, a multivariate logistic regression model was built using a stepwise procedure, and ORs and associated 95% CIs were calculated.
Results: Of the 349 study participants, 43 (12.3%) reported appropriate use of their asthma drugs. Respondents who were more likely to report appropriate use were patients with sound knowledge of their asthma drugs (OR 2.61 [95% CI 1.29 to 5.29]), those in good, very good or excellent self-perceived health (OR 3.37 [95% CI 1.31 to 8.71]), those who had consulted a specialist during the preceding year (OR 2.28 [95% CI 1.05 to 4.97]) and those who declared themselves short of drugs due to a lack of money (OR 2.78 [95% CI 1.26 to 6.17]).
Conclusions: Results of the present study suggested that recommendations in the current guidelines regarding the appropriate use of asthma medications are being poorly implemented. Educational interventions with the aim of improving quality of care and knowledge about asthma drugs should be offered.
HISTORIQUE :: Lorsqu’ils sont bien utilisés, les médicaments contre l’asthme peuvent réduire la morbidité et la mortalité liées à l’asthme.
OBJECTIF :: Évaluer l’utilisation des médicaments contre l’asthme et repérer les facteurs associés au bien-fondé de leur utilisation chez les patients de 12 à 45 ans.
MÉTHODOLOGIE :: Les chercheurs ont interviewé des patients asthmatiques au sujet de leur utilisation de médicaments contre l’asthme et des facteurs susceptibles d’être associés au bien-fondé de cette l’utilisation selon les lignes directrices 2003 de la Conférence canadienne de consensus sur l’asthme. Pour déterminer les facteurs associés à l’utilisation judicieuse de médicaments contre l’asthme, les chercheurs ont établi un modèle de régression logistique multivariée à l’aide d’une intervention progressive et ont calculé les RRR et les IC 95 %.
RÉSULTATS :: Parmi les 349 participants à l’étude, 43 (12,3 %) ont déclaré une utilisation judicieuse de leurs médicaments contre l’asthme. Les répondants les plus susceptibles de déclarer une telle utilisation étaient ceux qui connaissaient très bien leurs médicaments contre l’asthme (RRR 2,61 [95 % IC 1,29 à 5,29]), ceux qui percevaient leur santé comme bonne, très bonne ou excellente (RRR 3,37 [95 % IC 1,31 à 8,71]), ceux qui avaient consulté un spécialiste pendant l’année précédente (RRR 2,28 [95 % IC 1,05 à 4,97]) et ceux qui déclaraient manquer de médicaments par manque d’argent (RRR 2,78 [95 % IC 1,26 à 6,17]).
CONCLUSIONS :: D’après les résultats de la présente étude, les recommandations des lignes directrices portant sur l’utilisation judicieuse des médicaments contre l’asthme sont peu mises en œuvre. Il faudrait donc offrir des interventions pédagogiques visant à améliorer la qualité des soins et les connaissances sur l’asthme.
