There are about 28871 clinical studies being (or have been) conducted in Canada. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Potentially inappropriate medications (PIMs) can lead to adverse drug events (ADEs) among older adults and especially those classified as frail. ADEs are responsible for nearly 27,000 hospital admissions in Canada annually. Within 30 days of discharge, medications contribute to two-thirds of adverse events, with nearly 60% being preventable or ameliorable. MedSafer is software product that guides patients and physicians in the community through the process of deprescribing. MedSafer electronically cross-references patient comorbidities with the most recent evidence-based PIMs, as of the study date, in order to generate a patient-tailored deprescribing care plan. This study will evaluate whether this application, when applied at hospitalization, leads to a reduction in the proprotion of patients with PIMs prescribed at discharge, by highlighting harmful medications for deprescription to treating physicians. This study will take place on the clinical teaching units (CTUs) at four hospitals. Based on historical records, the investigators estimate enrolling 480 patients aged 65 or older over three months. A trained research assistant will identify eligible patients, and will enter their medications, comorbidities, and an estimate of frailty into MedSafer. A deprescribing plan will be generated for the CTU team containing rationale for suggested medication changes and strategies for safe and successful deprescription. The CTU team will then decide in conjunction with the patient or proxy, and with relevant consultants, which medications can rationally be stopped or tapered at discharge.
This is a Phase IIb, randomized, placebo-controlled, double-blind, multicenter, multi-arm study which will evaluate efficacy, safety, and pharmacokinetic of MSTT1041A compared with placebo as add-on therapy in participants with severe, uncontrolled asthma who are receiving medium- or high-dose inhaled corticosteroid (ICS) therapy and at least one of the following additional controller medications: long-acting beta-agonists (LABA), leukotriene modifier (LTM), long-acting muscarinic antagonist (LAMA), or long-acting theophylline preparation. The total duration of this study for each participant is approximately 70 weeks including screening, run-in, treatment, and follow-up.
Canadian and international health care systems require solutions on how to address the needs of a relatively small population that take up a large portion of health care resources. In Ontario, 10% of the population accounts for 79% of total system costs, with similar trends found in other parts of Canada and internationally. Most high-cost users are seniors, older adults, with multiple chronic conditions and complex care needs who are living in the community. Beyond the cost issues, older adults experiencing multi-morbidity are at higher-risk of poor health outcomes and experience lower quality of life as compared to individuals experiencing single illness only. Since April 2013 the electronic Patient Reported Outcomes (ePRO) mobile application and portal, has undergone a multi-phased, user-centred design evaluation approach to develop a tool designed to meet the needs of older adults with complex care needs and their primary care providers. The ePRO tool is designed to collect person-centred, person-reported indicators to improve care by supporting primary care delivery and enhancing patient self-management. The ePRO tool includes two features: 1) My Goal Tracker and 2) Health Journal. My Goal Tracker allows patients and providers to collaboratively create goal-oriented patient care-plans, and helps patients to track outcomes related to their goals using a mobile device. The Health Journal allows patients, their caregivers and primary care providers to monitor patients' symptoms and outcomes. The ePRO tool was re-evaluated and modified following each previous study phase (I-IV). This project marks the final phase of the study in which the investigators will conduct a pragmatic trial of the ePRO tool in 8-16 Family Health Teams in Ontario through a stepped-wedge randomized trial with an embedded case study. In this evaluation of the tool the investigators will assess outcome, process and context measures to identify how the tool affects patients, providers and the system at point-of-care.
Chronic obstructive pulmonary disease (COPD) is a chronic lung disease primarily caused by smoking. Pulmonary rehabilitation (PR) is an evidence-based, interdisciplinary, and comprehensive intervention for COPD patients that includes patient assessment, exercise training, and self-management education to promote behavior changes. PR has been shown to be the most effective strategy to improve clinical health outcomes, and is now considered to be a standard of care intervention for individuals with COPD who remain symptomatic despite optimal drug therapies. Despite considerable evidence supporting the effectiveness of PR at enhancing clinical outcomes, it is unclear if PR influences the behaviors that promote COPD management (i.e., physical activity, medication adherence, self-managing exacerbations). In collaboration with the local clinical staff as well as national colleagues and the Canadian Thoracic Society, a new national pulmonary rehabilitation program has been co-developed that is designed to increase physical activity, medication adherence, and skills to help manage chronic lung diseases. The new program aims to increase people's confidence and autonomy for performing disease-management behaviors, and has been designed to be more effective at increasing physical activity, medication adherence, and disease management skills than previous pulmonary rehabilitation programs. The program is designed to be delivered within different settings of practice, including traditional PR centers, satellite sites (i.e., sites that are remote from the major institutions),with the use of Tele-health and web-based resources, and primary care medical centers. The effectiveness of the new Standardized Canadian PR program will be assessed relative to the traditional PR program. This trial is an important step towards establishing the necessary evidence that will then enable us to work on dissemination and implementation of this new standardized PR program across the country.
Diagnostic imaging (DI) tests (for example, x-ray tests, ultrasounds, CT scans, or MRIs) are used by health care providers to help diagnose patient illness, but decisions regarding when these tests should be ordered are subjective. As a result, some physicians order these tests more than others. Ordering rates between clinicians seeing similar kinds of patients have been shown to be considerably different, suggesting that many of the tests are unnecessary. DI currently accounts for about 6.6% of Canadian hospital budgets, but this percentage may be much higher in Newfoundland where test ordering rates are almost twice the national average. However, cost is not the only concern. Over-testing can lead to further unnecessary testing to follow-up on harmless findings, and in the case of CT, large doses of potentially harmful radiation. We suspect that many clinicians are not aware that they order more DI tests than their peers. We will therefore develop a "report card" for family physicians in the province that shows them how many tests they are ordering compared to other physicians in the region. We expect that physicians who are over-ordering DI tests will reduce the number of tests they order after receiving their report cards. This is a low-cost way to potentially prevent expensive over-ordering of DI tests that can easily be implemented in the province's other health regions and elsewhere. The Quality of Care Newfoundland and Labrador (QCNL) organization in the province currently provides feedback reports and in-person detailing sessions to physicians, but the effectiveness of these interventions has not been studied.
This study aims to evaluate the risk of hyperoxia-induced hypercapnia in post-op obese cardiac surgery patients. It will compare two oxygenation modes in terms of their effect on the arterial partial pressure of carbon dioxide (PaCO2) : manual titration of oxygen delivery for a peripheral oxygen saturation (SpO2) target of > or = 95 % versus automatic titration by a closed-loop system for a SpO2 target of 90%. 15 post-op obese cardiac surgery patients will be recruited and each will receive both interventions (cross-over design). The main outcome will be the PaCO2, which will be compared after each study period. The research hypothesis is that the usual SpO2 target of > or = 95 % is associated with a greater PaCO2 compared with a lesser SpO2 target of 90%.
The study is a prospective, single centre, double-blinded randomized controlled trial whose goal is to compare the immune response of a population of immunosuppressed pediatric rheumatology patients on immunosuppressive medications to two different doses of Hepatitis A vaccine. The objectives are (a) to confirm that adolescents, like their adult counterparts, have a reduced immune response to hepatitis A vaccine, and (b) to compare the immunogenicity of two different dosing options of vaccine for this age group after one and two doses. A total of 60 adolescents aged 12 - 15 years with confirmed chronic rheumatologic conditions for which they are being treated with an immunosuppressive therapy will be recruited from the Rheumatology Clinic at Alberta Children's Hospital (ACH). Those found to have no immunity to hepatitis A will be enrolled. Informed, written consent will be obtained from the parent or guardian of subject, with assent obtained from the study subjects. Subjects will be randomly assigned to two doses of either Avaxim Pediatric® or Avaxim ® (adult) vaccine (Sanofi Pasteur Canada), six months apart, with hepatitis A titres done at baseline and one month after each dose. Both formulations are licensed for this age group.
The burden of bloodstream infections is large and increasing over time. Antibiotic overuse continues to drive increased rates of antimicrobial-resistant pathogens across Canada. However, prospective audits have revealed that 30-50% of antibiotic utilization is unnecessary or inappropriate. If shorter duration therapy is as effective as longer duration therapy for these infections, antimicrobial consumption would be decreased. A pilot trial (approved by the Sunnybrook Research Ethics Board), is underway in critically ill patients at 17 Canadian ICUs. Investigators have successfully demonstrated feasibility with respect to protocol adherence and recruitment rates in the ICU. Investigators now aim to conduct a similar pilot RCT among non-ICU patients admitted to hospital wards with bloodstream infections to determine feasibility and protocol adherence of the same trial protocol.
This is a 24 week, multicenter, randomized, double-blind, parallel group, placebo-controlled study to investigate the effects of saxagliptin and sitagliptin on cardiac dimensions and function in patients with type 2 diabetes (T2DM) mellitus and heart failure (HF).
This research study is being conducted to assess the safety and feasibility of using a new developed bronchoscopic technology called electronavigational bronchoscopy to treat subjects with solid tumor in peripheral lung, who are inoperable or refused surgery. It will involve 10 sites in USA and Canada. Participation will last 6 months.
