The author of this essay will critically appraise tow nursing articles. A qualitative paper published in the Journal of Advance Nursing (JAN) which will be referred as ‘article one’. A quantitative paper published in the Journal of Wound Care which will be referred as ‘article two’ in this essay. Both articles are wound care related. In order to examine the strength and weakness of the articles, the author of this essay will use a set of tools using a methodological analysis. Therefore demonstrate an understanding of the research process and relate to professional practice. There are several types of wounds for examples: postoperative, leg ulcer, diabetic and pressure sore (Sussman, 2012). Wounds can be acute or chronic in nature (Waugh & Grant, 2006). The process of healing is divided in three phases: inflammation, proliferation and remodelling (Waugh & Grant, 2006). The result of these biological process results in the replacement of a normal skin (Hawkins & Abrahamse, 2006). If the healing does not follow its normal process due to the presence of the debris. This will increase the level of bacteria and will lead to infection in the inflammation phase. This can contaminate the wound predispose to bacterial invasion in the blood and/or death of tissues (Sussman, 2012). Wound care in nursing is important, because it involves specifics treatments and care due to a complex healing process. To began with the article critique, Parahoo (2006) states that an abstract should briefly states the study aim, design, methods, sampling and main funding. Looking at both articles these are apparent. Looking at article one title and aim, it is apparent that, it is a qualitative study as words such as ‘quality of life’ and ‘inpatient perspectives’ are used. According to Cormack et al (2006), it is imperative to make title and aims explicit as it will draw the reader attention to the precise area of the study. The reader recognises the use of phenomenological approach in the article aim. This type of study falls under qualitative study. It attempts to interpret phenomena in terms of the meaning people make of them, by gathering from a small number of subjects an in-depth study of the phenomena (Lincoln, 2000). Qualitative approach does not show the frequency of something happening or count the instance of something which does not test hypothesis (Burn, 2004). Unlike quantitative study, it does not need participants to be randomly selected (Burn, 2004). In this article it is clear that qualitative study was the right methodology in order to understand participants’ experiences pressure ulcer. In article two, words such as ’randomised clinical trial’ and ‘compare’ are used in the objective. Randomise Control Trial or (RCT) is the experimental approach used. According to Stolberg et al (AJR, 2004) research, RCT falls under quantitative research. Quantitative research follows scientific methods which intends to measure facts (Silverman, 2005).The aim in this study is to compare two dressings by a clinical testing. If done properly RCT is said to be at the stop of the research hierarchy, as it is considered to be the best proof of evidence since results are more likely to be accurate (Parahoo,2006).A hypothesis or prediction is made by the researcher(s) at the start of a study which relate an independent variable to a dependant variable. A null hypothesis was established in the abstract’s summary as no difference was found between the two dressings. Cormack et al (2006), suggest that hypothesis should be capable of testing and use experimental approach. In this study the hypothesis appear to be testable. Although the reader of these articles feels that the methodologies used were appropriate in both articles, for Streubert and Carpenter (1999), the choice of methods depends on the questions being asked. Nevertheless both articles aim seems realistic and relate to the topic being investigated. Researching the literature using SPICE for the...
