The purpose of this assignment is to critique two research studies that I have identified from my practice. I am currently working as a community staff nurse within a District Nursing team (DN). Leg ulcers have a huge impact on the DNs workload, Moffat; Franks & Oldroyd (1992) evidenced that time spent by DNs caring for people with leg ulcers ranged from 9-22% of the total workload. Douglas (2001) informs us that leg ulceration affects around 1% of the population. This evidence has provided the author with a rationale to review the literature regarding the contemporise issue of Doppler assessmenDts with an aim to measure the reliability and validity of this type of clinical procedure. Learning outcomes to be met will be indicated in bold lettering at the end of each appropriate paragraph. In order to practice competently nurses must possess the knowledge, skills and abilities required for lawful, safe and effective practice (Nursing and Midwifery Council NMC 2004). Evidence based practice therefore is the integration of best research evidence with clinical expertise and patient values (Sackett, Strauss & Richardson 200). Having identified the topic area, a structured approach to the literature review was undertaken as recommended by Polit & Beck (2006). The search involved identifying literature related to the chosen topic. A computerised literature search was carried out using the following databases; Cinahl, Cochrane, Internurse, Journal of Wound Care and Pubmed (see Appendix.1.). McShay & Haddock (1999) & Polit & Beck (2006) believe that in order to develop evidence based practice it is necessary to identify areas of practice that can be clinically questioned, identify relevant evidence from available information, critically appraise the evidence for validity and usefulness and then implement the findings into clinical practice (LOC 1, 2 &3). For the purpose of this assignment, the critique framework by Cormack (2000), (appendices. 2.), has been selected as it provides a comprehensive series of questions that are presented in a clear and concise manner, which allows for thorough critical analysis of the chosen research studies. However it must be noted that not all aspects of Cormack’s (2000) framework will be critiqued, due to the type of research articles being critiqued, not all questions need to be answered. The two research articles chosen are
1) Community nurse uses of Doppler ultrasound in leg ulcer assessment by Lorraine French (2005) see (Appendices. 3.).
2) Pulse oximetry index: a simple arterial assessment for patients with venous disease, by Bianchi et al (2008) see (Appendices. 4.).
Polit & Beck (2006), Bond (2000) and Tierney (1996) state that the title of an article should clarify the topic of research and to give an indication of the content, all research articles should have a meaningful and unambiguous title. The title of both French’s (2005) article and Bianchi et al (2008) are concise, informative and clearly indicates the contents of the article. However, they both fail to outline the research approach used by the author. Polit & Beck (2006) advocate that in quantitative studies the title usually indicates the independent and dependent variables and the population, again, French’s (2005) article does not, however Bond (2000) feels that too much complexity regarding the title may deter the reader from pursuing further reading.
When critically reviewing research articles it is important that there is information provided relating to the relevance and appropriateness of the authors academic and professional qualifications, and their experience to perform such research (Cormack 2000). French (2005) appears adequately qualified both academically and professionally to perform the study as she is a qualified nurse and clinical specialist and possesses a higher degree in Vascular Nursing. Bianchi et al (2008) also all appear adequately qualified; between them on paper...
