RésuméIntroductionAfin de réduire les risques de résistance aux antibiotiques et autres anti-infectieux, plusieurs organismes gouvernementaux et sociétés savantes se sont positionnés sur l'usage optimal de ces médicaments. Nous nous sommes donc intéressés au profil d'utilisation des antibiotiques et aux sensibilités bactériennes associées.ObjectifsL'objectif principal de cette étude était de décrire le profil de consommation et de sensibilité des antibiotiques au sein d'un centre hospitalo-universitaire mère-enfant canadien. Les objectifs secondaires étaient d'explorer s'il existe une corrélation entre le profil de consommation d'antibiotiques et la sensibilité bactérienne.MéthodeIl s'est agi d'une étude rétrospective, descriptive et transversale qui s'est déroulée sur cinq ans dans un centre hospitalier mère-enfant. Ont été inclus tous les enfants et tous les pathogènes comportant au moins 30 tests de sensibilité par exercice financier. Le nombre de jours de traitement par 1000 jours-présence a été utilisé pour évaluer la consommation d'antibiotiques. Des coefficients de corrélation de Pearson ont été calculés.RésultatsPour la période d'étude (2010-2011 à 2014-2015), la consommation globale d'antibiotiques est restée relativement stable (le nombre de jours de traitement/1000 jours-présence est passé de 927,5 à 866,2). Le profil de sensibilités bactériennes a varié de façon importante pour plusieurs paires antibiotique-bactérie. Seules trois corrélations étaient statistiquement significatives, soit : Pseudomonas aeruginosa-ceftazidime (p = 0,01), P. aeruginosa-ciprofloxacine et consommation de fluoroquinolones (p = 0,02), Enterococcus sp.-ampicilline et consommation de pénicillines (p = 0,04).ConclusionIl reste difficile de montrer des corrélations entre consommation d'antibiotiques et sensibilité bactérienne, cependant ces données sont particulièrement utiles dans le cadre du programme d'antibiogouvernance.
SummaryIntroductionTo reduce risks of antibiotic resistance, governmental and learned societies decreed the optimal use of antibiotics. The relation between antibiotic consumption and bacterial resistance increase has been clearly demonstrated over the last several years. Antibiotic consumption data and bacterial sensitivity data are regularly published, but very few publications have searched for a correlation between these two variables. This study focused on antibiotic use and consumption as well as bacterial sensitivity to these antibiotics.ObjectivesThe main objective was to describe the changes in antibiotic consumption and bacterial sensitivity in a mother-child teaching hospital. The secondary objectives were to explore whether antibiotic use and bacterial sensitivity were correlated and to comment on the usefulness of these data for clinicians.MethodsThis was a 5-year retrospective, descriptive, cross-sectional study. All samples from usually sterile biologic liquids of hospitalized pediatric patients were included in the study. The samples from outpatient clinics were excluded. All types of bacteria identified in more than 30 isolates were included in the study. The antibiotics usually used to treat these bacteria were included. To assess antibiotic consumption, we calculated the number of days of therapy per 1000 patient-days for hospitalized pediatric patients and we calculated the Pearson correlation coefficient between antibiotic consumption and sensitivity rates to these antibiotics. Two scenarios were explored: one with correlation by year and one with the next year for bacterial sensitivity.ResultsDuring the study period (2010-2011 to 2014-2015), overall antibiotics consumption remained relatively stable. Concerning bacterial sensitivity, we noted important changes (sensitivity rates increased for 12 antibiotic-bacteria pairs, remained stable for five, and decreased for 15). We found three significant correlations for the first scenario: Pseudomonas aeruginos-ceftazidime (P = 0.01), P. aeruginosa-ciprofloxacin and fluoroquinolone consumption (P = 0.02), Enterococcus sp-ampicillin and penicillin consumption (P = 0.04). For the second scenario, we found only two significant correlations: coagulase-negative Staphylococcus-oxacilline and penicillin consumption (P = 0.02), P. aeruginosa/piperacillin (P = 0.04).ConclusionThis exploratory study allowed us to describe antibiotic consumption and bacterial sensitivity progression. To our knowledge, this is the first study exploring the correlation between antibiotic consumption and the bacterial sensitivity rate in pediatrics in Canada. It remains very difficult to show this correlation between these two variables because of the multiple sources of bacterial resistance. These data are particularly useful for the antimicrobial stewardship programs and for clinicians.
