1. Association of serotype with respiratory presentations of pneumococcal infection, Ontario, Canada, 2003-2011.

    Vaccine 34(6):846 (2016) PMID 26602266

    Pneumococcal disease burden is difficult to quantify due to limited data regarding non-bacteremic disease. We assessed serotype-specific differences in pneumococcal disease presentations in adults in Toronto, Canada. From 2003 to 2011, population-based surveillance for invasive pneumococcal dise...
  2. Invasive Pneumococcal Disease Among Immunocompromised Persons: Implications for Vaccination Programs.

    Clinical Infectious Diseases 62(2):139 (2016) PMID 26354970

    In 2012/2013, a single dose of 13-valent pneumococcal conjugate vaccine (PCV13) was recommended for immunocompromised adults in the United States and Canada. To assess the potential benefits of this recommendation, we assessed the serotype-specific burden of invasive pneumococcal disease (IPD) a...
  3. Factors Associated With Complications of Clostridium difficile Infection in a Multicenter Prospective Cohort.

    Clinical Infectious Diseases 61(12):1781 (2015) PMID 26338788 PMCID PMC4657538

    Clostridium difficile infection (CDI) is the most common cause of nosocomial infectious diarrhea and may result in severe complications including death. We conducted a prospective study to identify risk factors for complications of CDI (cCDI). Adult inpatients with confirmed CDI in 10 Canadian h...

  10. An educational forum to engage infectious diseases and microbiology residents in resource stewardship modelled after the Choosing Wisely campaign.

    The Canadian journal of infectious diseases = J... 26(5):231 (2015) PMID 26600804 PMCID PMC4643999

    Rising costs present a major threat to the sustainability of health care delivery. Resource stewardship is increasingly becoming an expected competency of physicians. The Choosing Wisely framework was used to introduce resource stewardship at a national educational retreat for infectious disease...
  11. Reducing the risk of infection in a 74-year-old man who is to receive prednisone.

    Canadian Medical Association Journal 186(16):1239 (2014) PMID 25024293 PMCID PMC4216257

  12. Previous antibiotic exposure and antimicrobial resistance in invasive pneumococcal disease: results from prospective surveillance.

    Clinical Infectious Diseases 59(7):944 (2014) PMID 24973312

    Estimating the risk of antibiotic resistance is important in selecting empiric antibiotics. We asked how the timing, number of courses, and duration of antibiotic therapy in the previous 3 months affected antibiotic resistance in isolates causing invasive pneumococcal disease (IPD). We conducted...

    Clinical Infectious Diseases 58(7):980 (2014) PMID 24577290

    This proof-of-concept study demonstrates that no longer routinely reporting urine culture results from noncatheterized medical and surgical inpatients can greatly reduce unnecessary antimicrobial therapy for asymptomatic bacteriuria without significant additional laboratory workload. Larger stud...
