BACKGROUND Colorectal cancer (CRC) fulfills the World Health Organization criteria for mass screening, but screening uptake is low in most countries. CRC screening is resource intensive, and it is unclear if an optimal strategy exists. The objective of this study was to perform an economic evaluation of CRC screening in average risk North American(More)
BACKGROUND The effectiveness of quality improvement (QI) strategies on diabetes care remains unclear. We aimed to assess the effects of QI strategies on glycated haemoglobin (HbA(1c)), vascular risk management, microvascular complication monitoring, and smoking cessation in patients with diabetes. METHODS We identified studies through Medline, the(More)
BACKGROUND Chronic kidney disease (CKD) is a major public health problem. In the UK, guidelines have been developed to facilitate case identification and management. Our aim was to estimate the annualized cost of implementation of the guidelines on newly identified CKD cases. METHODS We interrogated the New Opportunities for Early Renal Intervention by(More)
BACKGROUND Diabetes is regarded as a coronary heart disease risk equivalent-ie, people with the disorder have a risk of coronary events similar to those with previous myocardial infarction. We assessed whether chronic kidney disease should be regarded as a coronary heart disease risk equivalent. METHODS We studied a population-based cohort with measures(More)
Although anemia is common in older adults, its prognostic significance is uncertain. A total of 17 030 community-dwelling subjects 66 years and older were identified between July 1 and December 31, 2001, and followed until December 31, 2004. Cox proportional hazards analyses were performed to determine the associations between anemia (defined as hemoglobin(More)
BACKGROUND Acute kidney injury (AKI) is associated with early mortality after percutaneous coronary revascularization procedures, but its prognostic relevance to long-term clinical outcomes remains controversial. METHODS AND RESULTS We conducted a retrospective study of 14782 adults who received coronary angiography in the province of Alberta, Canada,(More)
BACKGROUND Low values of estimated glomerular filtration rate (eGFR) predispose to acute kidney injury, and proteinuria is a marker of kidney disease. We aimed to investigate how eGFR and proteinuria jointly modified the risks of acute kidney injury and subsequent adverse clinical outcomes. METHODS We did a cohort study of 920,985 adults residing in(More)
BACKGROUND Hemodialysis patients are at risk for deficiency of essential trace elements and excess of toxic trace elements, both of which can affect health. We conducted a systematic review to summarize existing literature on trace element status in hemodialysis patients. METHODS All studies which reported relevant data for chronic hemodialysis patients(More)
BACKGROUND AND OBJECTIVES Although the accepted standard of care for induction of lupus nephritis has been cyclophosphamide, recent trials suggest that mycophenolate mofetil may be as or more effective and less toxic. A systematic review and meta-analysis were performed to determine the risk for failure to induce remission of lupus nephritis in patients who(More)
BACKGROUND The Alberta Kidney Disease Network is a collaborative nephrology research organization based on a central repository of laboratory and administrative data from the Canadian province of Alberta. DESCRIPTION The laboratory data within the Alberta Kidney Disease Network can be used to define patient populations, such as individuals with chronic(More)
