Diabetes, another indicator associated with the Waterlow scale, is prevalent in 6. Waterllw pressure ulcer is defined as a lesion of the skin or underlying tissue, usually over a bony prominence, as a result of pressure associated with friction forces.

The analysis process of the study data was divided into two stages. Diabetes is responsible for causing metabolic, macro and microvascular disorders because of chronic hyperglycaemia.
For this, nurses should conduct periodic evaluations to identify the risk of PUs and improve their knowledge about the use of measurement scales for PUs [ 13 ].
The Norton scale remained unchanged. National Center for Biotechnology InformationU. The first five sub-scales have a score ranging from 1 to 4, while the scores of the friction and shear sub-scales range from 1 to 3.
These scales have already been evaluatedseparately 4,in pairs 14 and together 8, Universidade do Extremo Wscala Catarinense; Evaluation of the escalx ulcers risk scales with critically ill patients: These evaluations shortly after the hospitalization of the patients in intensive care are critical, as, in many cases, there is an indication of restriction to the bed, use of vasoactive drugs, mechanical ventilation and sedation. The incidence of pressure ulcers after the implementation of a prevention protocol.
Therefore, various risk assessment instruments have been developed and some of them have been validated in Brazil, with the Braden and Waterlow scales among the most commonly used Complications of pressure ulcers in severely ill patients: Ulcers are classified into six categories: Am J Crit Care.
The Norton scale assesses five parameters for PUrisk: This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License, which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Older people have decreased adipose tissue and collagen fibres with a reduced blood supply from the decreased capillaries in the skin, which interferes with adequate blood perfusion [ 25 ].
After 15 days of hospitalization in an ICU, all patients have some risk for developing a PU, especially bedbound elderly patients [ 7 ]. The occurrence of PUs in patients in the postoperative period is presented in another study, in which variables related to surgical patients, such as length of anesthesia and extent of the surgery, were predictive for the development of PUs Besides these four items that score specialrisk factors, there are: Mortality is related to the worsening of clinical conditions.
Design A cross-sectional study was conducted on patients admitted in the adult ICU of a university hospital in Northeast Brazil. Regarding the performance of both the Braden and Waterlow scales, they presented high sensitivity and low specificity in the three evaluations. This scale assesses seven main topics: The reduction of the incidence of PUs can decrease hospital costs and optimize the care provided by the nursing staff [ 9 ].
For the Braden scale, the evaluation of the ROC curve Figure 3 showed that it did not present a good prediction of risk of watdrlow patient developing pressure ulcers. The mean values at the first, second and third evaluations were Given the severity of the problem for the patient, the family and the institution, the need to prevent PUs is undeniable 8.
Pressure ulcers increase hospital stays and treatment costs due to their complications. In this sense, the average age of the individuals was An early and regular stratification of the watrelow ofdeveloping a PU is essential to adopt adequate preventivemeasures on an appropriate therapeutic strategyimplementation.

During the admission process, the following clinicalsituations were verified as the most common ones: Risk factors for pressure ulcerdevelopment in institutionalized elderly. To this end, it provides the following classifications: In critically ill patients the use of these instruments should occur daily as a result of changes in the clinical conditions requiring the implementation of appropriate preventive behaviors after the diagnosis of risk To evaluate the association between the scores of the Waterlow, Braden, and Norton scales and clinical and social characteristics in critically ill patients.

Therefore, recognition of risk factors for critically ill patients can help reduce the risk of PUs escalx 15 ]. Pressure ulcer prevalence and incidence in intensive care patients: Most did not receive guidance before the onset pressure ulcers; only some of them were advised.
