Background: We reviewed numerous variables for ischemic stroke patients admitted to a rehabilitation unit to determine those that were statistically associated with discharge destination. Methods: A retrospective chart review of patients with ischemic stroke discharged from the rehabilitation unit between January 1, 2005 and December 31, 2015. Variables were examined for their association with discharge destination (home versus long-term care (LTC)). Univariable relationships with discharge destination were assessed, and a multivariable logistic regression model was built. Results: Univariate predictors of discharge to LTC: advanced age, decreasing admission and discharge functional independence measure (FIM) scores, increasing change in FIM score from admission to discharge, dependency, residence outside of home before the stroke, absence of a caregiver, urinary and bowel incontinence, low Berg balance score at admission and discharge, low Montreal Cognitive Assessment scores, smoking, chronic heart failure, and an inability to transfer. Multivariable logistic regression: five factors remained significant predictors with LTC disposition: advanced age, bowel incontinence, residence outside of the home prior to stroke, right hemisphere site of the stroke, and absence of a caregiver. Conclusions: Several easily measured variables were significantly associated with discharge to LTC versus home following stroke rehabilitation.

Understanding consumers' food safety practices and knowledge supports food safety education for the prevention of foodborne illness. The objective of this study was to describe Canadian consumer food safety practices and knowledge. This study identifies demographic groups for targeted food safety education messaging and establishes a baseline measurement to assess the effectiveness of food safety interventions over time. Questions regarding consumer food safety practices and knowledge were included in a population-based telephone survey, Foodbook, conducted from November 2014 to March 2015. The results were analyzed nationally by age group and by gender. The results showed that approximately 90% of Canadians reported taking the recommended cleaning and separating precautions when handling raw meat to prevent foodborne illness. Only 29% of respondents reported using a food thermometer when cooking any meat, and even fewer (12%) reported using a food thermometer for small cuts of meat such as chicken pieces. The majority (>80%) of Canadians were aware of the foodborne illness risks related to chicken and hamburger, but fewer (

The objective of this work was to describe trends in multiple-class antimicrobial resistance present in clinical isolates of Escherichia coli F4, Pasteurella multocida and Streptococcus suis from Ontario swine 1998–2010. Temporal changes in multiple-class resistance varied by the pathogens examined; significant yearly changes were apparent for the E. coli and P. multocida data. Although not present in the E. coli data, significant increases in multiple-class resistance within P. multocida isolates occurred from 2003 to 2005, coinciding with the expected increase in antimicrobials used to treat clinical signs of Porcine Circovirus Associated Disease (PCVAD) before it was confirmed. Prospective temporal scan statistics for multiple-class resistance suggest that significant clusters of increased resistance may have been found in the spring of 2004; months before the identification of the PCVAD outbreak in the fall of 2004.

Monitoring the volume and patterns of use of antimicrobial agents is important in light of antimicrobial resistance.To assess the use of three antimicrobial groups - tetracycline, sulfonamide-trimethoprim and 'other' antimicrobials - within Canadian provinces over time.Prescription counts from 1995 to 2010 were acquired for the tetracycline and sulfonamide-trimethoprim groups of antimicrobials, and from 2001 to 2010 for the 'other' antimicrobial group. Linear mixed models were produced to assess differences among provinces and over time while accounting for repeated measurements. Prescription rate, defined daily dose per 1000 inhabitant-days and defined daily doses per prescription measures for the year 2009 were also compared with those reported by participating European Union countries to determine where Canadian provinces rank in terms of antimicrobial use among these countries.Prescribing of all three groups varied according to province and over time. Tetracycline and sulfonamide-trimethoprim group prescribing were significantly reduced over the study period, by 36% and 61%, respectively. Prescribing of the 'other' antimicrobial group increased in all provinces from 2001 to 2010 with the exception of Prince Edward Island, although by varying amounts (10% to 61% increases).The overall use of antimicrobials in Canada has dropped from 1995 to 2010, and the tetracycline and sulfonamide-trimethoprim groups have contributed to this decline. The use of the 'other' antimicrobials has increased, however. These results may suggest that switches are being made among these groups, particularly among the antimicrobials used to treat urinary tract infections.Il est important de surveiller le volume et le mode d’utilisation des antimicrobiens compte tenu de la résistance antimicrobienne.Évaluer l’utilisation de trois groupes d’antimicrobiens, soit la tétracycline, la sulfonamide-triméthoprime et d’« autres » antimicrobiens dans les provinces canadiennes au fil du temps.Les chercheurs ont obtenu le nombre de prescriptions des groupes de tétracycline et de sulfonamide-triméthoprime entre 1995 et 2010 et du groupe d’« autres » antimicrobiens entre 2001 et 2010. Ils ont produit des modèles linéaires mixtes pour évaluer les différences entre les provinces et dans le temps tout en tenant compte des mesures répétées. Ils ont également comparé le taux de prescriptions, les doses quotidiennes définies par 1 000 habitants-jours et les doses quotidiennes définies par mesures de prescription à ceux des pays participants de l’Union européenne en 2009 pour déterminer le classement des provinces canadiennes en matière d’utilisation d’antimicrobiens au sein de ces pays.Les prescriptions des trois groupes de médicaments variaient selon la province et dans le temps. La prescription des groupes de tétracycline et de sulfonamide-triméthoprime a diminué considérablement pendant la période de l’étude, soit de 36 % et de 61 %, respectivement. La prescription du groupe d’« autres » antimicrobiens a augmenté dans toutes les provinces entre 2001 et 2010, à l’exception de l’Île-du-Prince-Édouard, mais selon des taux différents (augmentations de 10 % à 61 %).L’utilisation globale d’antimicrobiens a diminué au Canada entre 1995 et 2010, et les groupes de tétracycline et de sulfonamide-triméthoprime y ont contribué. L’utilisation d’« autres » antimicrobiens a toutefois augmenté. Ces résultats laissent peut-être supposer des substitutions entre ces groupes, notamment entre les antimicrobiens utilisés pour soigner les infections urinaires.

Because antimicrobial use is commonly associated with the development of antimicrobial resistance, monitoring the volume and patterns of use of these agents is important.To assess the use of quinolone antimicrobials within Canadian provinces over time.ANTIMICROBIAL PRESCRIBING DATA COLLECTED BY IMS HEALTH CANADA WERE ACQUIRED FROM THE CANADIAN INTEGRATED PROGRAM FOR ANTIMICROBIAL RESISTANCE SURVEILLANCE AND THE CANADIAN COMMITTEE FOR ANTIMICROBIAL RESISTANCE, AND WERE USED TO CALCULATE TWO YEARLY METRICS: prescriptions per 1000 inhabitant-days and the mean defined daily doses (DDDs) per prescription. These measures were used to produce linear mixed models to assess differences among provinces and over time, while accounting for repeated measurements.The quinolone class of antimicrobials is used similarly among Canadian provinces. Year-to-year increases in quinolone prescribing occurred from 1995 to 2010, with a levelling off in the latter years. Year-to-year decreases in the DDDs per prescription were found to be significant from 2000 to 2010.Although the overall use of antimicrobials differs significantly among Canadian provinces, the use of the quinolone class does not vary at the provincial level. Results suggest that prescribing of ciprofloxacin may be a potential target for antimicrobial stewardship programs; however, decreases in the average DDDs per prescription suggest continued uptake of appropriate treatment guidelines.Puisque l’utilisation d’antimicrobiens s’associe souvent à l’apparition d’une résistance antimicrobienne, il est important d’en surveiller le volume et le mode d’utilisation.Évaluer l’utilisation d’antimicrobiens de la classe des quinolones au sein des provinces canadiennes au fil du temps.Les chercheurs ont acquis les données de prescription d’antimicrobiens colligées par IMS Health Canada auprès du Programme intégré canadien de surveillance de la résistance aux antimicrobiens et du Comité canadien sur la résistance aux antibiotiques et les ont utilisées pour calculer deux mesures annuelles : les prescriptions par 1 000 habitants-jours et les doses quotidiennes définies (DTD) moyennes par prescription. Ils les ont utilisées pour produire des modèles linéaires mixtes afin d’évaluer les différences entre les provinces et au fil du temps, tout en tenant compte des mesures répétées.Les antimicrobiens de la classe des quinolones sont utilisés de manière similaire dans les provinces canadiennes. Les prescriptions annuelles de quinolone ont augmenté de 1995 à 2010, mais ont plafonné au cours des dernières années. Les DTD par prescription ont diminué annuellement de manière significative entre 2000 et 2010.Même si l’utilisation globale d’antimicrobiens diffère de manière significative entre les provinces canadiennes, l’utilisation de la classe des quinolones ne varie pas sur la scène provinciale. D’après les résultats, la prescription de ciprofloxacine peut être une cible potentielle des programmes de gestion des antimicrobiens. Cependant, les diminutions des DTD moyennes par prescription sont indicatrices d’une assimilation continue des directives thérapeutiques pertinentes.

Introduction Acute rhinosinusitis (ARS) is a respiratory disease commonly caused by viral infections. Physicians regularly prescribe antibiotics despite bacterial etiologies being uncommon. This is of concern, as this use adds to the selection pressure for resistance. Here we present the descriptive epidemiology of acute rhinosinusitis and corresponding antibiotic prescribing practices by Canadian outpatient physicians from 2007–2013. Materials/Methods Diagnosis and antibiotic prescription data for ARS were extracted from the Canadian Disease and Therapeutic Index for 2007 to 2013, and population data were acquired from Statistics Canada. ARS diagnosis and antibiotic prescription rates and frequencies of antibiotic classes were calculated. Results Eighty-eight percent of patients diagnosed with ARS in 2013 were adults, with a greater rate of antibiotic prescriptions observed among the adults relative to the pediatric patients (1632.9 and 468.6 antibiotic prescriptions per 10,000 inhabitants). Between 2007 and 2013, the ARS diagnosis rate decreased from 596 to 464 diagnoses per 10,000 inhabitants, while the percentage of diagnoses with antibiotic prescriptions at the national level remained stable (87% to 84%). From 2007 to 2013, prescription rates for macrolides decreased from 203.5 to 105.4 prescriptions per 10,000 inhabitants. In 2013, penicillins with extended spectrum were more commonly prescribed compared to macrolides among adult patients (153.5 and 105.4 prescriptions per 10,000 inhabitants, respectively). Conclusion This study is the first to describe physician antibiotic prescribing practices for treatment of ARS in Canada. Results show that antibiotic treatment for ARS represents an area for implementing antimicrobial stewardship, and through it, managing antibiotic resistance. Further work is required to better understand diagnosing practices and treatment criteria for ARS, and use this information to further assist physicians to limit unnecessary antibiotic prescribing practices.

The volume and patterns of antimicrobial drug use are key variables to consider when developing guidelines for prescribing, and programs to address stewardship and combat the increasing prevalence of antimicrobial resistant pathogens. Because drug programs are regulated at the provincial level, there is an expectation that antibiotic use may vary among provinces.To assess these potential differences according to province and time.Provincial antimicrobial prescribing data at the individual drug level were acquired from the Canadian Integrated Program for Antimicrobial Resistance Surveillance for 2000 to 2010. Data were used to calculate two yearly metrics: prescriptions per 1000 inhabitant-days and the average defined daily doses per prescription. The proportion of liquid oral prescriptions of total prescriptions was also calculated as a proxy measure for the proportion of prescriptions given to children versus adults. To assess the significance of provincial antimicrobial use, linear mixed models were developed for each metric, accounting for repeated measurements over time.Significant differences among provinces were found, as well as significant changes in use over time. Newfoundland and Labrador was found to have significantly higher prescribing rates than all other provinces (P0.001) in 2010, as well as the mean of all other provinces (P0.001). In contrast, Quebec exhibited significantly lower prescribing than all other provinces (P0.001 for all provinces except British Columbia, where P=0.024) and the mean of all other provinces (P0.001).Reports of reductions in antimicrobial use at the Canadian level are promising, especially prescribing to children; however, care must be taken to avoid the pitfall of the ecological fallacy. Reductions are not consistent among the provinces or among the classes of antimicrobial drugs dispensed in Canada.Le volume et les modes d’utilisation d’antimicrobiens sont des variables importantes à envisager lorsqu’on élabore des lignes directrices de prescription et des programmes pour aborder la question de la gouvernance et pour lutter contre la prévalence croissante des pathogènes résistants aux antimicrobiens. Puisque les programmes de médicaments sont réglementés sur la scène provinciale, on s’attend que l’utilisation d’antibiotiques varie entre les provinces.Évaluer ces différences potentielles selon la province et dans le temps.Les chercheurs ont extrait les données sur la prescription de chaque médicament antimicrobien sur la scène provinciale du Programme intégré canadien de surveillance de la résistance aux antimicrobiens entre 2000 et 2010. À l’aide de ces données, ils ont calculé deux mesures annuelles : les prescriptions par 1 000 habitants-jours et les doses thérapeutiques quotidiennes moyennes dispensées par prescription. Ils ont également calculé la proportion de prescriptions orales liquides par rapport aux prescriptions totales pour établir approximativement la proportion de prescriptions administrées aux enfants par rapport aux adultes. Pour évaluer l’importance de l’utilisation d’antimicrobiens sur la scène provinciale, les chercheurs ont élaboré des modèles linéaires mixtes pour chaque mesure, tenant compte de mesures répétées dans le temps.Les chercheurs ont constaté des différences significatives entre les provinces, ainsi que des changements importants d’utilisation dans le temps. Ils ont déterminé que Terre-Neuve-et-Labrador présentait des taux de prescription considérablement plus élevés que toutes les autres provinces (P0,001) en 2010, ainsi que de la moyenne de toutes les autres provinces (P0,001). Par contre, le Québec présentait des taux de prescription considérablement plus faibles que toutes les autres provinces (P0,001 pour toutes les provinces sauf la Colombie-Britannique, où P=0,024) ainsi que de la moyenne de toutes les autres provinces (P0,001).Les rapports sur la diminution de l’utilisation d’antimicrobiens sur la scène canadienne sont prometteurs, notamment les prescriptions aux enfants. Cependant, il faut s’assurer d’éviter l’écueil des erreurs écologiques. Les réductions ne sont pas uniformes entre les provinces ou entre les classes d’antimicrobiens administrées au Canada.

Background With rising reports of antimicrobial resistance in outpatient communities, surveillance of antimicrobial use is imperative for supporting stewardship programs. The primary objective of this article is to assess the levels of antimicrobial use in Canada over time. Methods Canadian antimicrobial use data from 1995 to 2010 were acquired and assessed by four metrics: population-adjusted prescriptions, Defined Daily Doses, spending on antimicrobials (inflation-adjusted), and average Defined Daily Doses per prescription. Linear mixed models were built to assess significant differences among years and antimicrobial groups, and to account for repeated measurements over time. Measures were also compared to published reports from European countries. Results Temporal trends in antimicrobial use in Canada vary by metric and antimicrobial grouping. Overall reductions were seen for inflation-adjusted spending, population-adjusted prescription rates and Defined Daily Doses, and increases were observed for the average number of Defined Daily Doses per prescription. The population-adjusted prescription and Defined Daily Doses values for 2009 were comparable to those reported by many European countries, while the average Defined Daily Dose per prescription for Canada ranked high. A significant reduction in the use of broad spectrum penicillins occurred between 1995 and 2004, coupled with increases in macrolide and quinolone use, suggesting that replacement of antimicrobial drugs may occur as new products arrive on the market. Conclusions There have been modest decreases of antimicrobial use in Canada over the past 15 years. However, continued surveillance of antimicrobial use coupled with data detailing antimicrobial resistance within bacterial pathogens affecting human populations is critical for targeting interventions and maintaining the effectiveness of these products for future generations.

Background The objective of this work was to retrospectively assess records received through the Ontario Swine Veterinary-based Surveillance program July 2007 – July 2009 to describe and assess relationships between reported treatment failure, antimicrobial use, diagnosis and body system affected. Results Antimicrobial use occurred in 676 records, 80.4% of all records recording treatment (840). The most commonly used antimicrobials were penicillin (34.9%), tetracyclines (10.7%) and ceftiofur (7.8%), and the use of multiple antimicrobials occurred in 141/676 records (20.9%). A multi-level logistic regression model was built to describe the probability of reported treatment failure. The odds of reported treatment failure were significantly reduced if the record indicated that the gastro-intestinal (GI) system was affected, as compared to all other body systems (p
