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.
CONTEXTE: L'Agence de la santé et des services sociaux de Montréal (ASSS) invited our research team to evaluate the implementation of an integrated and interdisciplinary primary care network for prevention and management of cardiometabolic risks (diabetes and hypertension) (PCR). The intervention is based on the Chronic Care Model and the development of an integrated services network. PCR is to be implemented in 6 territories of "Centre de santé et de services sociaux (CSSS)". A first application for funding was made to Fonds Pfizer-FRSQ-MSSS for an evaluation that has to be completed in the first 24 month after the beginning of the implementation. This application to the PHSI program at CIHR is complementary and will ensure an evaluation of the sustainability of PCR and of long term effects (40 months after the beginning of the implementation) for patients and for their primary care physicians. In each CSSS, PCR plans for : 1- an interdisciplinary team in an education center working with primary care physicians and offering to referred patients a pre-determined sequence of clinical interventions over a 2-year-period; 2- a program supporting primary care physicians (continuing education, documentation and clinical guidelines, referral system to second line of care); 3- networking between actors of "Réseau local de services (RLS)" insuring clinical information transfer required for efficient patient management. OBJECTIVES: 1-evaluate PCR effects according to territory, time and degree of exposure (specifically benefits to registered patients and support to participating primary care physicians); 2- identify the degree of implementation of PCR in each CSSS territory and the related contextual factors; 3- examine the relationship between the effects identified, the degree of implementation of PCR and the related contextual factors; 4- assess the impact of implementing PCR on the strengthening of RLS. METHODS: The proposed evaluation will be done through a mixed design including two complementary strategies. Using a "quasi-experiment/before-after" design, the first strategy is a quantitative approach looking at the program effects and their variation between territories. This analysis will use data from the PCR clinical database (ex.: HbA1c, BP, lifestyle) and from patient questionnaire inquiring about care experience, utilization of services, chronic care follow-up, self-management and quality of life. Around 3000 patients will be enlisted. A primary care physician questionnaire will enquire about PCR effects on their practice. Using primarily a qualitative and a case study approach, each of the 6 territories being one case, the second strategy will identify the degree of implementation of PCR and the explanatory contextual factors. This analysis with use data obtained from semi-structured interviews with program managers. The results of this analysis will be summarized in a monograph for each territory. According to the type of indicator analyzed, objective 3 will be fulfilled using linear models or longitudinal multilevel models supplemented with an interpretive approach using the information from monographs and discussion groups. The impact of implementing PCR on RLS will be assessed through interviews with key informants. RESULTS AND EXPECTED IMPACT: Our study will identify the effectiveness of PCR and contextual factors associated with successful implementation and sustainability of PCR. Detailed contextual information will allow application of our results to other environments that have similar context and to other chronic conditions that could benefit from an integrated services network. KNOWLEDGE TRANSFER: Since decision makers, clinicians and researchers did and will take part in all phases of PRC evaluation (planning, data collection, analysis and interpretation), diffusion of information regarding the program is an integral part of the research process. In addition, results will be presented at local, regional, provincial and national conferences and published in reports and articles widely distributed. More specifically, a regional symposium will be organized to share evaluation results with all CSSS in the region (n=12) and with all our local and regional partners.
The purpose of this study is to determine how intraocular pressure responds to changes in the levels of carbon dioxide or oxygen that a healthy individual inspires.
Objective: Continuous nerve block (freezing the nerve) is needed for knee replacement surgery to reduce pain, increase rehabilitation and discharge patients home fast. A lot of time, money and hospital resources are invested in inserting these catheters. The aim of this study is to compare two end points used for insertion of continuous femoral nerve block and to see which one results in fewer failures on the surgical ward. Methodology: Patients having total knee replacement surgery will be recruited in this study. Patients will be randomized into two groups. The continuous femoral nerve block catheter will be inserted using ultrasound and nerve stimulation with two different end points (certain muscle contraction). Patients will be followed on day 1 and 2 after surgery to observe which catheter fails, how much pain the patient suffers and how much painkiller the patients used.
Ranibizumab (Lucentis, Genentech) is an off-label drug used for the clinical treatment of central retinal vein occlusion, which is one of the most common retinal vascular disorders. Despite its clinical effectiveness, concerns remain regarding the systemic effects of the drug and previous studies have noted retinal arteriolar vasoconstriction following a ranibizumab injection. We aim to provide a physiological basis to these observations by assessing retinal blood flow before and after the ranibizumab injections. Specifically, we will assess the blood flow parameters (i.e. retinal vessel diameter, velocity & flow) immediately before the first injection and post-injection over a follow-up continued treatment period.
The carotid arteries are blood vessels in the neck that supply blood to the brain. Carotid stenosis disease is defined as a narrowing of these arteries due to the build up of plaque. The plaque material can also break off and move into the brain. The resulting blockage of blood supply to a portion of the brain is what causes 80% of all strokes. One treatment option is to have surgery on the carotid artery and remove the plaque. This procedure is called a carotid endarterectomy (CEA). There is evidence that proves CEA reduces the risk of stroke. The objective of this research project is to determine who is most likely to benefit from CEA surgery.
Strength of the Quadriceps Muscle is key to recover from Total Knee Arthroplasty. In this study we compare two techniques for pain control after total knee arthroplasty in terms of preserving the motor function (the strength of the quadriceps muscles of the thigh) which will facilitate the rehabilitation and accelerate the hospital discharge. We will use ultrasound guided technique to block either the femoral nerve in the control group or the saphenous nerve in the experimental group. The primary outcome is the functional capacity and the impact of each block on the ability to walk by measuring the distance patients are able to walk in two minutes in post operative day one in the two groups. The secondary outcome is the morphine consumption in the two groups.
The purpose of this study is to develop and implement a critical pathway to identify patients with ischemic cardiomyopathy who are candidates for an implantable cardioverter-defibrillator (ICD). This study will also determine whether the use of the critical pathway for ICDs is associated with a change in the ICD referral and implantation rate.
A Pilot Study to Evaluate the Safety and Efficacy of interferon-Alfacon1 (INFERGEN) in the treatment of patients hospitalized with Influenza-like illness caused by a novel swine origin Influenza virus and other circulating Influenza Viruses. The use of Interferon-alfacon1 as a co-treatment along with the standard of care antiviral is hypothesized to be safe. Clinical improvement of patients is hypothesized to be quicker.
The purpose of this study is to determine if the use of propofol only to achieve procedural sedation for the removal of third molars is both safe and effective.
The investigators are performing a study to determine whether changes in blood flow occur in the neck and back of the brain following a series of head positions and a manipulation of the upper neck. Each participant will be asked to undergo a series of MRI's to evaluate whether there are any changes in blood flow resulting from any of the head positions or manipulation. The study will be conducted over a period of 1 day and each participant can anticipate the testing to take approximately 120 minutes.
