Randomized Controlled Trial
Development and feasibility testing of decision support for patients who are candidates for a prophylactic implantable defibrillator: a study protocol for a pilot randomized controlled trial.
Patients, identified to be at risk for but who have never experienced a potentially lethal cardiac arrhythmia, have the option of receiving an implantable cardioverter defibrillator (ICD) as prophylaxis against sudden cardiac death - a primary prevention indication. In Canada, there is no clear framework to support patients' decision-making for these devices. Decision support, using a decision aid, could moderate treatment-related uncertainty and prepare patients to make well-informed decisions. Patient decision aids provide information on treatment options, risks, and benefits, to help patients clarify their values for outcomes of treatment options. The objectives of this research are: 1) develop a decision aid, 2) evaluate the decision aid, and 3) determine the feasibility of conducting a trial. ⋯ Our study seeks to develop a decision aid, for patients offered their first ICD for prophylaxis against sudden cardiac death. This paper outlines the background and methods of a pilot randomized trial which will inform a larger multicenter trial. Ultimately, decision support prior to specialist consultation could enhance the decision-making process between patients, physicians, and families, associated with life-prolonging medical devices like the ICD.

Randomized Controlled Trial
PARot--assessing platelet-rich plasma plus arthroscopic subacromial decompression in the treatment of rotator cuff tendinopathy: study protocol for a randomized controlled trial.
Platelet-rich plasma (PRP) is an autologous platelet concentrate. It is prepared by separating the platelet fraction of whole blood from patients and mixing it with an agent to activate the platelets. In a clinical setting, PRP may be reapplied to the patient to improve and hasten the healing of tissue. The therapeutic effect is based on the presence of growth factors stored in the platelets. Current evidence in orthopedics shows that PRP applications can be used to accelerate bone and soft tissue regeneration following tendon injuries and arthroplasty. Outcomes include decreased inflammation, reduced blood loss and post-treatment pain relief. Recent shoulder research indicates there is poor vascularization present in the area around tendinopathies and this possibly prevents full healing capacity post surgery (Am J Sports Med36(6):1171-1178, 2008). Although it is becoming popular in other areas of orthopedics there is little evidence regarding the use of PRP for shoulder pathologies. The application of PRP may help to revascularize the area and consequently promote tendon healing. Such evidence highlights an opportunity to explore the efficacy of PRP use during arthroscopic shoulder surgery for rotator cuff pathologies. ⋯ PARot is a single center, blinded superiority-type randomized controlled trial assessing the clinical outcomes of PRP applications in patients who undergo shoulder surgery for rotator cuff disease. Patients will be randomized to one of the following treatment groups: arthroscopic subacromial decompression surgery or arthroscopic subacromial decompression surgery with application of PRP.

Randomized Controlled Trial
Effectiveness of off-the-shelf footwear in reducing foot pain in Australian Department of Veterans' Affairs recipients not eligible for medical grade footwear: study protocol for a randomized controlled trial.
Foot pain is highly prevalent in older people, and in many cases is associated with wearing inadequate footwear. In Australia, the Department of Veterans' Affairs (DVA) covers the costs of medical grade footwear for veterans who have severe foot deformity. However, there is a high demand for footwear by veterans with foot pain who do not meet this eligibility criterion. Therefore, this article describes the design of a randomized controlled trial to evaluate the effectiveness of low cost, off-the-shelf footwear in reducing foot pain in DVA recipients who are currently not eligible for medical grade footwear. ⋯ This study is the first randomized controlled trial to evaluate the effectiveness of off-the-shelf footwear in reducing foot pain in DVA recipients. The intervention has been pragmatically designed to ensure that the study findings can be implemented into policy and clinical practice if found to be effective.

The use of mindfulness-based cognitive therapy for improving quality of life for inflammatory bowel disease patients: study protocol for a pilot randomised controlled trial with embedded process evaluation.
Inflammatory bowel disease (IBD) is a chronic condition with an unpredictable disease course. Rates of anxiety and depression among IBD patients in relapse (active disease symptoms) as well as in remission are higher than in the general population. Previous studies suggest that the prolonged effect of pain, anxiety, distress and depression have a detrimental effect on patients'quality of life (QoL). Poor QoL in itself is associated with further symptom relapse. Mindfulness based cognitive therapy (MBCT) is a psychological group intervention that has the potential to improve QoL. When used in other chronic conditions, it demonstrated reduced negative effect from pain and psychological factors at completion of an 8-week MBCT course. The effect of MBCT has never been researched in IBD. The aim of this study is to obtain the information required to design a full scale randomised controlled trial (RCT) that will examine the effectiveness of MBCT in improving quality of life for IBD patients. ⋯ The outcomes of this study will help define the barriers, uptake and perceived benefits of MBCT program for IBD patients. This information will enable the design of a full-scale study assessing the effect of MBCT on quality of life for IBD patients.

The NAILED stroke risk factor trial (nurse based age independent intervention to limit evolution of disease after stroke): study protocol for a randomized controlled trial.
Secondary prevention after stroke and transient ischemic attack (TIA) is essential in order to reduce morbidity and mortality. Secondary stroke prevention studies have, however, been fairly small, or performed as clinical trials with non-representative patient selection. Long-term follow-up data is also limited. A nurse-led follow-up for risk factor improvement may be effective but the evidence is limited. The aims of this study are to perform an adequately sized, nurse-led, long-term secondary preventive follow-up with a population-based inclusion of stroke and TIA patients. The focus will be on blood pressure and lipid control as well as tobacco use and physical activity. ⋯ This study will test the hypothesis that a nurse-led, long-term follow-up after stroke with a focus on reaching set treatment goals as soon as possible, is an effective secondary preventive method. If proven effective, this method could be implemented in general practice at a low cost.
