OBJECTIVES: Renal replacement therapy is increasingly utilized in the intensive care unit (ICU), of which continuous renal replacement therapy (CRRT) is most common. Despite CRRT being a relatively invasive and resource intensive technology, there remains wide practice variation in its application. This systematic review appraised the evidence for quality indicators (QIs) of CRRT care in critically ill patients. DESIGN: A comprehensive search strategy was developed and performed in five citation databases (Medline, Embase, CINAHL, Cochrane Library, and PubMed) and select grey literature sources...

OBJECTIVES: Most are aware of pneumococcal infection as a complication of splenectomy and the increased risk of severe invasive pneumococcal disease (IPD) in asplenic patients. However little is known of the current status of this entity in a population with an active pneumococcal conjugate vaccine program for children. METHODS: All IPD cases reported from 2000 to 2014 in Northern Alberta, Canada were collected prospectively. Socio-demographic variables, clinical characteristics, and IPD-related outcomes were compared between patients with and without a spleen using the Student t-test, Chi-square test, or Fisher's exact test, as appropriate...

STUDY OBJECTIVE: To test a brief intervention for preventing statin nonadherence among community pharmacy patrons. DESIGN: Prospective, cluster-randomized, controlled trial (the Community Pharmacists Assisting in Total Cardiovascular Health [CPATCH] trial). SETTING: Thirty community pharmacies in Saskatchewan, Canada. PATIENTS: Participating pharmacies were randomized to 15 intervention pharmacies where a brief statin adherence intervention was delivered by pharmacists (intervention group [907 patients]) or 15 usual care pharmacies where no statin adherence intervention was delivered (usual care group [999 patients]) to new users of statins (defined as less than 1 yr of statin therapy)...

As choosing wisely has raised the issue of whether some individuals with type 2 diabetes may be overtreated, we examined the intensity of glycemic control across health status strata defined by comorbidities or frailty.This is a retrospective cohort study of commercially insured patients from 50 US states (Clinformatics Data Mart). We evaluated treated HbA1c levels in adults with new diabetes diagnosed between January 2004 and December 2009 who had HbA1C measured after at least 1 year of follow-up.Of 191,590 individuals with diabetes, 78...

BACKGROUND: Previous studies suggest that smoking is independently associated with decreased mortality in patients with pneumonia. We hypothesized that this is a result of acquiring differential pneumococcal serotypes (ie, smokers with pneumococcal pneumonia are more likely to experience bacteremia, with low case fatality rate (CFR) serotypes). We tested this hypothesis in a population-based cohort of patients with bacteremic pneumococcal pneumonia (BPP). METHODS: Our prospective population-based clinical registry included 1,636 adults (≥ 18 years) with BPP who were hospitalized between 2000 and 2010 in northern Alberta, Canada...

OBJECTIVE: We examined the correlates of sitting time in a population-based sample of older adults. METHODS: Adults >55 years of age (N = 1296; N = 515 employed; N = 781 unemployed) self-reported measures of demographic and health-related variables, and a measure of sitting time (ie, SIT-Q). RESULTS: Employed total sitting time (min/day) was positively associated with home Internet access (B = 71.2, 95% CI, 8.9 to 133.4, p = .025), body mass index (BMI) (kg/m(2); B = 7...

PURPOSE: The objective of this study was to determine if there is a dose-response relationship between sulfonylureas and major adverse cardiovascular events (MACE). METHODS: We conducted a retrospective cohort study among elderly patients with no history of acute coronary syndrome or stroke who initiated gliclazide or glyburide therapy between 1998 and 2010. Gliclazide and glyburide users were evaluated separately, and a high-dimensional propensity score (HDPS) was used to match patients initiating therapy with a low or high dose...

CONTEXT: Type 2 diabetes and osteoporosis are both common, chronic, and increase with age, whereas type 2 diabetes is also a risk factor for major osteoporotic fractures (MOFs). However, different treatments for type 2 diabetes can affect fracture risk differently, with metaanalyses showing some agents increase risk (eg, thiazolidinediones) and some reduce risk (eg, sitagliptin). OBJECTIVE: To determine the independent association between new use of sitagliptin and MOF in a large population-based cohort study...

OBJECTIVES: To evaluate the impact of continuity of care and multimorbidity on health outcomes in patients with diabetes. RESEARCH DESIGN: Using a US claims database of insured patients, we identified those with incident diabetes between 2004 and 2008 and followed them until death, disenrollment, or December 31, 2010. Continuity of care was defined using Breslau's Usual Provider of Continuity (UPC; proportion of visits to the usual or predominant provider within 2 y of diabetes diagnosis)...

INTRODUCTION: Low socioeconomic status (SES) should be a robust predictor of medication nonadherence because it shares key features with the theoretical origins of this phenomenon. However, population-based studies have demonstrated weak associations overall, possibly because SES is inadequately represented. We compared the performance of multiple versus single-domain measures of SES as predictors of statin adherence. METHODS: This retrospective cohort study used population-based administrative data mapped to area-level census information of individuals who received a statin medication following a hospitalization for coronary heart disease...

BACKGROUND: Animal models have demonstrated that sulfonylureas increase the size of myocardial infarction; however, data in humans is scarce. This study evaluated the association between sulfonylurea use and infarct size in diabetes patients with ST-elevation myocardial infarction (STEMI). METHODS: Consecutive STEMI patients admitted in Edmonton, Canada between 2006 and 2011 were enrolled in a regional prospective registry program. Patients with type 2 diabetes were identified from this group and the maximum recorded troponin I (max cTnI) within the first 48 h of chest pain onset was used as the primary outcome to quantify infarct size...

The evidence examining the effect of angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) on mortality in high-risk patients is conflicting. To further examine this controversy, the authors compared outcomes between ACE inhibitors and ARBs in a large clinical diabetes registry. A retrospective cohort of 87,472 incident users followed for 105,702 patient-years was analyzed. Average age was 53.1±10.1 years, 54.2% were men, and 14.4% had cardiovascular disease. All-cause hospitalization or all-cause mortality, the composite primary endpoint, occurred in 10,943 (12...
