OBJECTIVE To determine whether women with gestational diabetes mellitus (GDM) have an increased risk of cardiovascular disease (CVD) following pregnancy. RESEARCH DESIGN AND METHODS All women aged 20-49 years with live births between April 1994 and March 1997 in Ontario, Canada, were identified. Women with GDM were matched with 10 women without GDM and(More)
OBJECTIVE In vitro evidence shows that immune function is compromised in people with diabetes. Although certain rare infections are more common and infection-related mortality is higher, the risk of acquiring an infectious disease for diabetic patients has never been quantified. RESEARCH DESIGN AND METHODS A retrospective cohort study using administrative(More)
L anguage barriers may lead to poor quality of care for many reasons, including misdiagnosis, delays in care, decreased patient engagement and empowerment, and misuse of diagnostic testing. 1–3 However, for many medical conditions, clinical decision making can be based to a large extent on the result of objective physical examination findings , laboratory(More)
OBJECTIVE The definition of obesity (BMI ≥ 30 kg/m(2)), a key risk factor of diabetes, is widely used in white populations; however, its appropriateness in nonwhite populations has been questioned. We compared the incidence rates of diabetes across white, South Asian, Chinese, and black populations and identified equivalent ethnic-specific BMI cutoff values(More)
OBJECTIVE To examine the risk of new onset diabetes among patients treated with different HMG-CoA reductase inhibitors (statins). DESIGN Population based cohort study with time to event analyses to estimate the relation between use of particular statins and incident diabetes. Hazard ratios were calculated to determine the effect of dose and type of statin(More)
OBJECTIVE To determine in Canadian children aged <18 years the 1) incidence of type 2 diabetes, medication-induced diabetes, and monogenic diabetes; 2) clinical features of type 2 diabetes; and 3) coexisting morbidity associated with type 2 diabetes at diagnosis. RESEARCH DESIGN AND METHODS This Canadian prospective national surveillance study involved a(More)
BACKGROUND Surname lists are useful for identifying cohorts of ethnic minority patients from secondary data sources. This study sought to develop and validate lists to identify people of South Asian and Chinese origin. METHODS Comprehensive lists of South Asian and Chinese surnames were reviewed to identify those that uniquely belonged to the ethnic(More)
Reviews have repeatedly noted important methodological issues in the conduct and reporting of cluster randomized controlled trials (C-RCTs). These reviews usually focus on whether the intracluster correlation was explicitly considered in the design and analysis of the C-RCT. However, another important aspect requiring special attention in C-RCTs is the risk(More)
BACKGROUND Audit and feedback to physicians is commonly used alone or as part of multifaceted interventions. While it can play an important role in quality improvement, the optimal design of audit and feedback is unknown. This study explores how feedback can be improved to increase acceptability and usability in primary care. The trial seeks to determine(More)
BACKGROUND Audit and feedback to physicians is a commonly used quality improvement strategy, but its optimal design is unknown. This trial tested the effects of a theory-informed worksheet to facilitate goal setting and action planning, appended to feedback reports on chronic disease management, compared to feedback reports provided without these(More)
