Introduction

Research in Nursing has become a fundamental discipline throughout the years and this report will provide an insight into the process of research. This report will show how to use the Cinhal database to extract the best available article within the parameters of Tissue Viability and formulation of the research question. The main features will focus on the reliability and validity of the chosen topic of the Waterlow Scale tool and the comprehensive evaluation of the evidence. The main aim of this report is to validate the effectiveness of Waterlow Assessment Tool and identify any risk factors, towards the prevention of pressure ulcers. The overall strengths and weaknesses of the report will highlight any
This provides a structured format and numerical execution of the literature. Investigative design techniques to a study (such as this one) use theoretical principles (such as specificity and sensitivity) to choose the appropriate methods to answer the question being asked. (Sims, 2000). The quantitative methodology produced a convincing argument, in conjunction with a demographic survey tool , listing risk factors. For the identification of risk factors, ratios were mentioned using 95% confidence Intervals (CI) to estimate the demographic variables and provide a picture of the sample characteristics. (Burns, 2009).

Tools of data

The tool used to collect data consisted of the Waterlow Scale Tool and a demographic survey tool as mentioned above. The Waterlow scale tool was the used by nursing staff to collect data and is a recommended assessment tool of NHS. The demographic survey tool is a staging system derived by the National Pressure Ulcer Advisory Panel (NPUAP, 2010.), this tool was used by research nurses to obtain specified data for analysis. Other tools (such as Norton or Braden etc) could have been trialed but are not as prevalent.

There are limitations of scoring with these tools and have ambiguity associated of interpreting the results. J. Waterlow (2010) confirms that these assessment tools have some limitations and they can deviate from clinical judgment, although cutoff scoring
