ABSTRACT

BACKGROUND: Pressure injuries (PIs) are a major problem for healthcare providers, impacting both care costs and patients' quality of life, although they are predominately preventable. These injuries are especially present in Intensive Care Units (ICUs) as a result of the severity of the clinical conditions of patients in this unit. AIM: To develop a simplified version of the Braden scale by removing two of the most subjective subscores-Nutrition and Sensory Perception-in an attempt to reduce the chance of errors by the nursing team during the application of the scale. STUDY DESIGN: A cross-sectional study was conducted on data collected from patients admitted to the ICU of a private Brazilian tertiary hospital. The resulting data consisted of 5194 patients, 6353 hospital admissions, and 6974 ICU stays. The overall prevalence of PI was 1.09%. RESULTS: The T-test showed that both the Braden and the simplified Braden scores were significantly different between patients with and without PI (p < .001). Patients who developed PIs scored lower than those who did not. The area under the Receiver Operating Characteristic curve of the Braden Scale was 74.21% (95% CI: 68.61%-79.8%) and of the simplified scale was 72.54% (95% CI: 66.87%-78.22%). The Positive Predictive Value of the Braden Scale was 3.17% when interpolated at the same sensitivity as the simplified scale (47.37%), which achieved 3.26%. CONCLUSIONS: By removing two of the six subscores of the Braden scale we propose a new tool for identifying patients at risk of developing PI in a more objective and fast way. Our results show that classification performance had little negative impact. RELEVANCE TO CLINICAL PRACTICE: A simplified, less subjective scale allows for more precise and less time-consuming risk classification.
