The NHS incident rates (NICE, 2003) of pressure ulcers in the UK is a concern and this systematic review is an accepted, research approach in its own right and using descriptive statistical data measures the outcome of results more precisely (Gerrish, 2006). The measurable variables identified were positive predictive values (PPV), comorbidities, mobility and usefulness of the Waterlow tool in clinical practice. Background The researchers show the significant clinical problems of morbidity and mortality as a worthy argument for this study. Cost and financial burdens to the healthcare system are mentioned, prevalence of pressure ulcers at 12.7% necessitate the need for improvements in critical care settings. This study measures the effectiveness of the tool by using specific and sensitive PPV & NPV (negative predictive Vales) to define the myriad of variables. These variables and predictive outcomes and are an integral part of the validity and reliability of the studies outcome. (Sacket et al, 2000). Aim The aim of this article was to assess the validity of the Waterlow Scale instrument using a longitudinal cohort of internal medical patients. To identify risk factors contributing to the injury of pressure ulcers (information outlined in the abstract overview of the study) (BJN, 2010).
