The following ssion of this assignment attempts to critically appraise the venUS III randomised control trial (RTC) published in the British Medical Journal.
As a student/healthcare worker who is new to critical appraisal I am aware that I do not fully understand some of the calculations involved in reporting of findings, however Greenhalgh (2006) argued, ‘all you really need to know is what the best test is to apply in given circumstances, what it does and what might affect its validity/appropriateness’. When caring for patients it is essential that Healthcare Professionals …show more content…
Standard care comprised of low adherent dressings and four-layer bandaging that was high compression, reduced compression or no compression depending upon the participant’s tolerance. Any changes to the regime where recorded and where made at the discretion of the treating clinician. Standard care was practiced in accordance with local protocol and could have varied between locations the quality of standard care given may be considered to be a confounding variable. Surveys of reported practice of leg ulcer care by nurses have demonstrated that knowledge often falls far short of that which is ideal (Bell 1994, Moffat 2004, Roe 1994) and that there is a wide variation in the nursing management of people with leg ulcers in the United Kingdom (UK) (Elliot 1996, Moffat 2004, Roe 1994). Large variation in healing rates according to trial centre is a further indicator that standard care is so variable that it potentially affects the reliability of results. No treatment fidelity checks were undertaken and no observation regime beyond usual practice of the treating nurse’s practice was implemented despite nurses being new to ultrasound application. Nurses were deemed competent after one day of training, these nurses where then also considered competent to train other local nurses who would be providing treatment.
The ultrasound treatment given during the venous III trial did not give any additional effect on ulcer healing or reoccurrence rate and it

Evidence-Based Practice

Evidence-Based Practice (EBP) is a decision-making platform that is designed to provide high-quality patient quality care. EBP includes joining the best available research evidence along with expertise and patient values. According to Evidence-based nursing practice (EBNP) is the consistent clinical application of the most reliable, up to date evidence from well-designed studies and practice guidelines to improve the quality of patient care and patient outcomes. Evidence-based practice is patient…

Evidence Based Practice

Nursing practices need to mirror the constantly evolving world of life, and this is made possible by evidence-based practice. Evidence-Based Practice is the achievement of optimal patient care through the application of scientific data. Using evidence-based practice can be as intuitive as ambulating a patient that has a high risk for deep vein thrombosis, or as complex as recognizing the risks of prescribing a long-term anticoagulant to a high-risk geriatric patient. This type of practice has proven…

Evidence Based Practice

Evidence-based practice (EBP) involves using existing evidence to make decisions in clinical practice, rather than generating or confirming new knowledge. The purpose of EBP is to use the best evidence available to make patient care decisions. Most high-quality evidence comes from research studies, such as randomized controlled trials and systematic reviews. However, EBP combines research findings with clinical experience, patient preferences, and values. EBP acknowledges that expert opinions from…

goal of evidenced based practice (EBP) is for practitioner to apply the outcome of the study into clinical practice. “ It is the systemic process of reviewing the best available research evidence and then incorporating clinical experience and patient preferences into the mix.” EBP is becoming the gold standard for all health care practitioners in the international level as well. Studies have shown that patient’s health outcomes are greatly improved when health care is based on evidence from EBP and not…

As discussed above, in response to search of best practice, social work implemented scientific knowledge into practice. Evidence-based practice (EBP) is an approach that enables to identify the way in which professionals should make decisions by examining evidence that underlies for a practice and rating it according to how qualified or/and reliable it is. It promotes interpretation, integration, and collection of research derived evidence (McKibbon, Wilczynski, Hayward, Walker-Dilks, & Haynes, 1995)…

Introduction Evidence-based practices (EBP) are vital in public health programs to ensure that interventions are both effective and efficient. By integrating the best available scientific evidence with community needs and preferences, public health practitioners can design and implement interventions that improve health outcomes. This discussion explores the context of EBP in public health and the steps involved in implementing these practices. Context of Evidence-Based Practices in Public Health…

Evidence-Based Practice

Evidence-based practice (EBP) is aimed at implementing current clinical knowledge into care decisions to improve the patient care processes and outcomes. Moreover, it is a shared decision between patient and provider that incorporates research and best evidence with clinical expertise, as well as the patient’s values and preferences to make a desired heath outcome (Huber, 2014). Developing and fostering this type of practice can be hindered by the organizational culture of healthcare facilities.…

Research has come a long way since then, but implementing research into clinical practice is nevertheless important. However, not every research article contains valid or sufficient evidence to support a change in clinical practice. Nurses in general have the responsibility to evaluate published research outcomes for relevance and importance to nursing practice. Several ranking tools are available…
