Prominent publications by Andreas A Laupacis
BACKGROUND: Concerns regarding the safety of transfused blood have led to the development of a range of interventions to minimise blood loss during major surgery. Anti-fibrinolytic drugs are widely used, particularly in cardiac surgery and previous reviews have found them to be effective in reducing blood loss and the need for transfusion. Recently, questions have been raised regarding the comparative performance of the drugs and the safety of the most popular agent, ...

Importance: People who immigrate face unique health literacy, communication, and system navigation challenges, and they may have diverse preferences that influence end-of-life care.
Objective: To examine end-of-life care provided to immigrants to Canada in the last 6 months of their life.
Design, Setting, and Participants: This population-based cohort study (April 1, 2004, to March 31, 2015) included 967 013 decedents in Ontario, Canada, using validated linkages between health and ...

Oral Anticoagulants vs Aspirin in Nonvalvular Atrial Fibrillation: An Individual Patient Meta-analysis
[ PUBLICATION ]
CONTEXT: Patients with nonvalvular atrial fibrillation (AF) have an increased risk of stroke and other vascular events.
OBJECTIVE: To compare the risk of vascular and bleeding events in patients with nonvalvular AF treated with vitamin K -inhibiting oral anticoagulants or acetylsalicylic acid (aspirin).
DESIGN: Pooled analysis of patient-level data from 6 published, randomized clinical trials.
PATIENTS: A total of 4052 patients with AF randomly assigned to receive therapeutic doses of ...

Concern about risks of allogeneic transfusion has led to an interest in methods for decreasing perioperative transfusion. To determine whether cell salvage reduces patient exposure to allogeneic blood, we performed meta-analyses of randomized trials, evaluating the effectiveness and safety of cell salvage in cardiac or orthopedic elective surgery. The primary outcome was the proportion of patients who received at least one perioperative allogeneic red cell transfusion. Twenty-seven ...

Bisphosphonate Use and the Risk of Subtrochanteric or Femoral Shaft Fractures in Older Women
[ PUBLICATION ]
CONTEXT: Osteoporosis is associated with significant morbidity and mortality. Oral bisphosphonates have become a mainstay of treatment, but concerns have emerged that long-term use of these drugs may suppress bone remodeling, leading to unusual fractures.
OBJECTIVE: To determine whether prolonged bisphosphonate therapy is associated with an increased risk of subtrochanteric or femoral shaft fracture.
DESIGN, SETTING, AND PATIENTS: A population-based, nested case-control study to explore ...

CONTEXT: Drug-drug interactions are a preventable cause of morbidity and mortality, yet their consequences in the community are not well characterized.
OBJECTIVE: To determine whether elderly patients admitted to hospital with specific drug toxicities were likely to have been prescribed an interacting drug in the week prior to admission.
DESIGN: Three population-based, nested case-control studies.
SETTING: Ontario, Canada, from January 1, 1994, to December 31, 2000.
PATIENTS: All Ontario ...

CONTEXT: High levels of variation and inefficiency exist in current clinical practice regarding use of cervical spine (C-spine) radiography in alert and stable trauma patients.
OBJECTIVE: To derive a clinical decision rule that is highly sensitive for detecting acute C-spine injury and will allow emergency department (ED) physicians to be more selective in use of radiography in alert and stable trauma patients.
DESIGN: Prospective cohort study conducted from October 1996 to April 1999, ...

OBJECTIVES: The purpose of this study was to present radial and saphenous vein graft (SVG) occlusion results more than 5 years following coronary artery bypass surgery.
BACKGROUND: In the RAPS (Radial Artery Patency Study) study, complete graft occlusion was less frequent in radial artery compared with SVG 1 year post-operatively while functional occlusion (Thrombolysis In Myocardial Infarction flow grade 0, 1, 2) was similar.
METHODS: A total of 510 patients <80 years of age undergoing ...

A Patient Decision Aid Regarding Antithrombotic Therapy for Stroke Prevention in Atrial Fibrillation: A Randomized Controlled Trial
[ PUBLICATION ]
CONTEXT: Decision aids are tools designed to help patients participate in the clinical decision-making process.
OBJECTIVE: To determine whether use of an audiobooklet (AB) decision aid explaining the results of a clinical trial affected the decision-making process of study participants.
DESIGN: Randomized controlled trial conducted from May 1997 to April 1998.
SETTING: Fourteen centers that participated in the Stroke Prevention in Atrial Fibrillation (SPAF) III trial.
PARTICIPANTS: A ...

A Comparison of Aspirin with Placebo in Patients Treated with Warfarin after Heart-Valve Replacement
[ PUBLICATION ]
BACKGROUND: Despite the use of warfarin, major systemic embolism remains an important complication in patients with heart-valve replacement. Although the addition of antiplatelet agents has the potential to reduce this complication, their efficacy and safety when given in combination with warfarin are uncertain.
METHODS: In a randomized, double-blind, placebo-controlled trial, we assessed the efficacy and safety of adding aspirin (100 mg per day) to warfarin treatment (target ...

BACKGROUND: Atrial fibrillation is a leading preventable cause of recurrent stroke for which early detection and treatment are critical. However, paroxysmal atrial fibrillation is often asymptomatic and likely to go undetected and untreated in the routine care of patients with ischemic stroke or transient ischemic attack (TIA).
METHODS: We randomly assigned 572 patients 55 years of age or older, without known atrial fibrillation, who had had a cryptogenic ischemic stroke or TIA within ...

Effect of Selective Cyclooxygenase 2 Inhibitors and Naproxen on Short-term Risk of Acute Myocardial Infarction in the Elderly
[ PUBLICATION ]
BACKGROUND: Recent debate has emerged regarding the cardiovascular safety of selective cyclooxygenase 2 inhibitors and the possible cardioprotective effect of naproxen sodium. We compared the rates of acute myocardial infarction (AMI) among elderly patients dispensed selective cyclooxygenase 2 inhibitors, naproxen, and nonselective nonnaproxen nonsteroidal anti-inflammatory drugs (NSAIDs).
METHODS: We conducted a population-based retrospective cohort study using administrative health ...

Association of the Trauma of Hospitalization With 30-Day Readmission or Emergency Department Visit.
[ PUBLICATION ]
Importance: Trauma of hospitalization refers to the depersonalizing and stressful experience of a hospital admission and is hypothesized to increase the risk of readmission after discharge.
Objectives: To characterize the trauma of hospitalization by measuring patient-reported disturbances in sleep, mobility, nutrition, and mood among medical inpatients, and to examine the association between these disturbances and the risk of unplanned return to hospital after discharge.
Design, ...
