Systematic reviews constitute a valuable source of evidence for informed practice. By using transparent and systematic methods to collect, assess, summarise and synthesise evidence, they aim to provide an unbiased conclusion about the effect of interventions (Snilstveit, 2012). Policy makers can access to high quality evidence and use the findings of systematic reviews to make evidence-informed decisions (Petticrew and Roberts, 2006). Critical appraisal is the process of systematically and carefully examining research evidence to assess its trustworthiness, its value and relevance in a specific context (Mhaskar et al., 2009). The critical appraisal of the quality of systematic reviews is central to evidenced-based policymaking, allowing practitioners …show more content…
Given space limitations, there are several methodological issues that will not be covered in this critical appraisal; the issues that are discussed were chosen because they have the greatest relevance for formulating recommendations from the conclusions of this review. The review used a broad range of literature and critically appraised 130 studies. However, several limitations were identified. First, the resources used to search for studies were not adequate and failed to find a good deal of relevant information. Second, while the criteria for appraising studies were appropriate, no information was provided on how the limitations in the quality of study execution affected the overall quality of the articles included. Finally, the authors did not compile data in a useful manner: the issue of heterogeneity was not discussed, and the findings section did not consider variations of study quality. Using the findings from the appraisal exercise, the second part of this essay will present what policies or legal instruments could be considered as the most effective for preventing injuries related to firearms. Three types of laws were favoured. Vote counting was used as a method to frame recommendations from the findings of the review. The recommendations suggested can be considered as weak and should be interpreted with cautious as several limits arise such as the lack of external validity and

Systematic Review

...Systematic Review NUR/518 University of Phoenix Systematic Review The purpose of a systematic review is to attempt to find, evaluate and synthesize high quality research relevant to the research question. A systematic review uses carefully developed data collection and sampling procedures that are put in place in advance as a protocol. (Polit, 2012). A systematic review must contain the following: a clear inclusion and exclusion criteria, an explicit search strategy, systematic coding and analysis of included studies, and a meta-analysis if possible. (Hemingway & Brereton, 2009). Systematic reviews are conducted by nurse researchers to avoid reaching incorrect or misleading conclusions that could arise from a biased study. Systematic reviews are perceived by many as the cornerstone of evidence-based practice. (Polit, 2012). The issue of concern that this article addresses is “to systematically evaluate nurse working conditions and to review the literature dealing with their association with patient outcomes.” (Bae, 2011). “The aim of this study is to fulfill two objectives: a systematic evaluation of nurse working conditions and a review of the literature dealing with the association between nurse working conditions and patient outcomes. The innovative review of research on working conditions focused on the relationships between nurse working conditions and patient outcomes.” (Bae, 2011). The author of this systematic review, Dr. Sung-Hei Bae, is currently...

...Promoting Evidence-Based Education: The Role of Practitioners Round table presented at the British Educational Research Association Conference, Cardiff University, 7-10 September 2000 Robert Coe, Carol Fitz-Gibbon and Peter Tymms Curriculum, Evaluation and Management Centre, Durham University Mountjoy Research Centre 4, Stockton Road, Durham DH1 3UZ Tel: 0191 374 4504; Fax: 0191 374 1900; Email: r.j.coe@dur.ac.uk http://www.cem.dur.ac.uk/ebeuk Abstract A number of recent initiatives from Durham University’s Curriculum, Evaluation and Management Centre have sought to involve teachers in creating, accessing and applying evidence about what works in their practice. The ‘gold-standard’ of evidence in this context is taken to be multiple replications of small scale, randomised controlled trials of feasible interventions in real-life settings. The aims, form and progress of these initiatives will be reported, and a number of questions will be raised: What do we mean by ‘Evidence-Based Education’? How can it best be promoted? What kinds of research can teachers do? How good can it be? Can it genuinely contribute to knowledge? Is it a distraction or enhancement of teachers’ core role? How do traditional models of Action Research fit with this approach? Is there an existing body of knowledge that can inform practice? How can teachers gain access to it? Under what conditions might such knowledge have an impact on practice? ...

...METHODOLOGY The objective of this chapter is to define nursing research, analyse methods of research and outline methodological process used to find articles on which to base this extended literature review. In this hypothesis, the reason for literature review is to ascertain whether or not gastric banding is an effective treatment for obesity in young adults as measured by physical functioning. The research process is the step-by-step procedure of developing research paper (Boje, 2001). It normally consists of following stages: detection of the research problem; preparation of search plan; searching and assessing the literature; data collection and evaluation; formulating a research design; and presenting the research findings (Cormack, 1996). The ability of nurses and other health care professionals to locate and identify existing literature on a relevant topic is an essential nursing skill (Burns & Grove, 2003). The sources where they can gain and expand research knowledge from may include personal or specialist experiences and clinical procedures and guidelines (Eccles & Mason, 2001). Before they can be made assessable to health care workers, guidelines and procedures are required to go through rigorous process of dissemination, before they can be made assessable to health care workers to be used in practice (Craig & Smith, 2007). Some of the organisations responsible for underwriting and implementation of clinical guidelines into clinical practice...

Metaanalysis Critique

...a Cochrane Review Meta-Analysis Study Educational and Skills-based Interventions for Preventing Relationship and Dating Violence in Adolescents and Young Adults Critique of a Cochrane Review Meta-Analysis Study There is a high rate of violence between young adults in relationships. As this is becoming more prevalent it is important to strengthenone’s knowledge base to help prevent this form of violence. A meta-analysis is a process to combine the findings from several independent research studies in a statistical manner. This method is used most often to evaluate the rational and useful way associate several research studies to determine effectiveness of an intervention (Crombie& Davies, 2009). A critique of a study is, “a careful appraisal of the strengths and weaknesses of a study” (Polit & Beck, 2008, p. 123). These show areas of inadequacy and adequacy within a research study and to identify any errors. Within this paper there will be a critique of the Cochrane Review Meta-Analysis, “Educational Skills-based Interventions for Preventing Relationship and Dating Violence in Adolescents and Young Adults.” This critique will have several divisions; identification of the level of evidence, describe the search of the literature and the adequacy of the search, description of the replication process, discuss any problems or differences, identify gaps within the literature, discuss any limitations within the study, discuss the strengths of the review, describe the...

Evidence Based Practise in Nursing

...Hand hygiene is a practise of evidence-based medicine and the number one way to prevent health-care associated infections (Garbutt, 2011). The term of hand hygiene applies to adequate hand washing, antiseptic hand-wash, antiseptic hand-rub, or surgical hand antisepsis (Garbutt, 2011). Evidence-based practices have been put into place to prevent such infections from occurring. The present paper will examine ways in which health professionals use the five steps of evidence based practices (EBP) to locate, appraise and apply the best available research evidence. In this case, the five steps of EBP will be assessed in conjunction to the practise of good hand hygiene. Liamputtong (2013, p.267) has explained evidence-based practise (EBP) as the use of the best research evidence, clinical expertise, available resources, and patient preferences in respect to clinical decision-making. EBP is taught and practised using five steps to reduce inconsistency and increase efficiency and effectiveness of health care (Liamputtong, 2013, p.267). According to Liamputtong (2013, p.267) the first step of EBP is to ask an answerable question stating the population, intervention, comparison and outcome of the question (PICO). Next, acquire the best available evidence using research strategies (Liamputtong, 2013, p.267). This evidence is then appraised to determine its quality and relevance (Liamputtong, 2013, p.267). The fourth step it to apply the evidence integrated with clinical expertise and...

...overcoming barriers and applying best research. Examples of this include use of professional protective equipment and safety considerations when using equipment. Liamputtong (2010) states that evidence based practice is a “process that requires the practitioner to find empirical evidence about the effectiveness or efficacy of different treatment options and then determine the relevance of the evidence to a particular clients situation” (pp. 252). Sackett (1996, pp.71) states that “conscientious, explicit and judicious use of current best evidence in making decisions about the care of individuals patients. The practice of evidence based medicine means integrating individual clinical expertise with the best available external evidence from systematic research, and the more thoughtful identification and compassionate use of individual patients’ predicaments,...

Nursing and Workplace Violence

...come from blood borne pathogens, chemical exposures or falls, but comes directly from people as evident in workplace violence(Fernandes, Bouthillette, Raboud, Bullock, Moore, Rae, Ouellet, Gillrie & Way, 1999). The effects of workplace violence is far-reaching and costly(Hoag-Apel, 1998). In fact according to the international council of nurses “ health care workers are more likely to be attacked at work than prison guards and police officers”(ICN, 2009). The aim of this essay is to critically appraise a systematic review of the literature based on workplace violence in the emergency department and to identify characteristics of interventional studies to guide best practice. This review will discuss current practices in reference to NSW health policy and guidelines, critique the systematic review by (Taylor & Rew, 2010) in terms of discussing methodology and provided a comprehensive overview of (Taylor & Rew, 2010) article(Hoag-Apel, 1998) (NSW Health, 2005). Finally, this review will attempt to recommend a change in practice in terms of the research question of what are the suggested interventions for workplace violence in the ED conducted by studies from 2004 ? Based on best evidence based practice and research(Hoag-Apel, 1998) . Although healthcare professionals and exclusively nurses are at higher risk of workplace violence, NSW legislation doesn’t reflect the increase risk associated or current international concerns(Hoag-Apel, 1998) . In NSW it is part of a legislative...

...available. However, to keep abreast with the continuously increasing number of publications in health research, a primary health care professional would need to read an unsurmountable number of articles every day covered in more than 13 million references and over 4800 biomedical and health journals in Medline alone.1 With the view to address this challenge, the systematic review method was developed.2 This article provides a practical guide for appraising systematic reviews for relevance to clinical practice and interpreting meta-analysis graphs as part of quantitative systematic reviews. A systematic review is a synthesis of primary research studies investigating a clearly formulated clinical question using systematic, explicit and reproducible methods. The Cochrane Library is probably the most comprehensive collection of regularly updated systematic reviews in the health field and is freely accessible in Australia.3 Some systematic reviews qualify for a quantitative statistical summary of comparable study findings, the meta-analysis. While useful guides to systematic review methodology and critical appraisal of systematic reviews are plentiful, 4–6 there is a paucity of practical guides to appraisal of meta-analysis for the nonstatistician. This article provides a practical guide to appraisal of meta-analysis graphs, and has been developed as part of the Primary Health Care Research Evaluation Development (PHCRED) capacity building program for training general practitioners and other...

Hlsc122 : Sam Is a Recently Graduated Health Professional and Has Observed That Clinical Practices Vary in the Different Health Care Facilities. Sam Is Confused About Which Practice Is the Most Effective to Give

...Sam is a recently graduated health professional, who during his time at university has been taught about evidence based practice (EBP). His first experience of implementing the five steps of EBP, asking an answerable question, acquiring the evidence, appraising the evidence, applying the evidence and assessing the process Liamputtong (2010), will be critically analysed in this essay. An encounter of qualitative and quantitative approaches to research, and how Sam can apply the evidence generated from a quantitative approach to evidence based clinical practice will be detailed below. Evidence based practice can be defined as clinical decisions for individual patients derived from the most appropriate evidence available (Facchiano & Snyder, 2012). It is a nurse’s care of duty to use appropriate clinical practice that will best suit the needs of the patient. Implementation of EBP based on an understanding of research findings is a requirement of competency standards for Australian and New Zealand nurses and midwifes (Borbasi & Jackson, 2012). Sam noticed conflicting practices while watching a routine wound clean; tap water was used instead of saline solution by one of his fellow nurses. This made Sam begin to think about what evidence there was to support using water, or if the nurse should have used saline instead. Sam decided to research this topic further, which comprised of him asking a targeted question that he could then translate into research. The clinical question...

Word count: 3720. An investigation into the use of cord treatments on the new-borns umbilical cord and the reduction of infection. A Literature Review. INTRODUCTION. The purpose of this literature review is to examine the evidence surrounding umbilical cord care in the new-born and what part the use of topical treatments play (if any) in the reduction of infection to the new-born infant. The umbilical cord is a unique tissue consisting of two arteries and one vein. Wharton’s jelly surrounds the vessels. During pregnancy the umbilical cord assists the placenta by transporting nutrients and waste products to and from the fetus. (Fraser, M. et al 2009). Following delivery of the neonate the cord goes through a process were it dries out, hardens and turns black. The area goes through a process of colonization due to non-pathogenic organisms that pass from mum to baby via skin to skin contact following delivery. The umbilical vessels remain patent for several days following birth and are a susceptible site for infection. Potentially harmful organisms can be spread by cross infection, often caused by poor hand washing techniques of Healthcare workers and the infant’s carers. (Davies, S. 2008). The World Health Organisation (WHO) reports each year one third of neonatal...

The Health System Strategy Division at the Ministry of Health and Long-Term Care subsequently asked the secretariat to provide an evidentiary platform for the ministry's newly released Aging at Home Strategy.After a broad literature review and consultation with experts, the secretariat identified 4 key areas that strongly predict an elderly person's transition from independent community living to a long-term care home. Evidence-based analyses have been prepared for each of these 4 areas: falls and fall-related injuries, urinary incontinence, dementia, and social isolation. For the first area, falls and fall-related injuries, an economic model is described in a separate report.Please visit the Medical Advisory Secretariat Web site, http://www.health.gov.on.ca/english/providers/program/mas/mas_about.html, to review these titles within the Aging in the Community series.AGING IN THE COMMUNITY: Summary of Evidence-Based AnalysesPrevention of Falls and Fall-Related Injuries in Community-Dwelling Seniors: An Evidence-Based AnalysisBehavioural Interventions for Urinary Incontinence in Community-Dwelling Seniors: An Evidence-Based AnalysisCaregiver- and Patient-Directed Interventions for Dementia: An Evidence-Based AnalysisSocial Isolation...
