BACKGROUND Survivors of acute kidney injury are at an increased risk of developing irreversible deterioration in kidney function and in some cases, the need for chronic dialysis. We aimed to determine predictors of chronic dialysis and death among survivors of dialysis-requiring acute kidney injury. METHODS We used linked administrative databases in(More)
BACKGROUND Over the last decade, several new antihyperglycemic medications have been introduced including those associated with a lower hypoglycemia risk. We aimed to investigate how these medications are being prescribed to older adults in our region. METHODS We conducted population-based cross-sectional analyses of older adults (mean age 75 years) with(More)
OBJECTIVE For various reasons, people of Chinese (China, Hong Kong or Taiwan) and South Asian (Indian subcontinent) ancestry (the two largest ethnic minority groups in Ontario, Canada) may be less likely to register for deceased organ donation than the general public, and their families may be less likely to consent for deceased organ donation at the time(More)
STUDY QUESTION Do men starting treatment with prostate-specific α antagonists have increased risk of fall and fracture? METHODS Administrative datasets from the province of Ontario, Canada, that contain patient level data were used to generate a cohort of 147,084 men aged ≥ 66 years who filled their first outpatient prescription for prostate-specific α(More)
BACKGROUND Administrative data are increasingly being used to assess outcomes in kidney transplant recipients. OBJECTIVE To assess the validity of transplant data in healthcare administrative databases compared to the reference standard of information collected directly from transplant centres. DESIGN Retrospective cohort study. SETTING One of three(More)
OBJECTIVE To characterize the 90-day risk of hospitalization with pneumonia among patients treated with different anti-hypertensive drug classes. DESIGN Population based cohort study using five linked databases. PARTICIPANTS Individuals over the age of 65 who filled a new outpatient prescription for one of four anti-hypertensive medications: ACE(More)
BACKGROUND The risk of ventricular arrhythmia with citalopram and escitalopram is controversial. In this study we investigated the association between these two drugs and the risk of ventricular arrhythmia. METHODS We conducted a population-based retrospective cohort study of older adults (mean age 76 years) from 2002 to 2012 in Ontario, Canada, newly(More)
BACKGROUND Compared to Caucasians, Chinese achieve a higher blood concentration of statin for a given dose. It remains unknown whether this translates to increased risk of serious statin-associated adverse events amongst Chinese patients. METHODS We conducted a population-based retrospective cohort study of older adults (mean age, 74 years) newly(More)
BACKGROUND We lack consensus on the clinical value, frequency, and timing of bone mineral density (BMD) testing in kidney transplant recipients. This study sought to determine practice patterns in BMD testing across kidney transplant centres in Ontario, Canada, and to compare the frequency of testing in kidney transplant recipients to non-transplant(More)
BACKGROUND We previously demonstrated that assessment of the duration of AKI, in addition to magnitude of rise in creatinine alone, adds prognostic information for long-term survival. We evaluated whether post-operative kidney injury biomarkers in urine collected immediately after cardiac surgery associate with duration of serum creatinine elevation. (More)
