SUMMARY OBJECTIVE: The aim of this study was to assess the inter-reliability of the Braden scale and its subscales for different patients assisted in the intensive care unit. We hypothesized that the Braden scale has low reliability in different populations. METHODS: This reliability study involved the Braden scale in intensive care unit of a hospital. A total of 200 patients were admitted to the intensive care unit in four different groups: neurological patients, sepsis, elderly, and adults affected by trauma. The Braden scale is a tool composed of six subscales for patient assessment: sensory perception, humidity, activity, mobility, nutrition, and friction. The total score was also calculated. The Braden scale was applied by two different nurses with an interval of 20–30 min between applications. RESULTS: For all populations, kappa values considered unsuitable were observed for most categories of the Braden scale, ranging from 0.06–0.25. Only for the total Braden scale score was moderate reliability identified in all groups evaluated, with intraclass correlation coefficient values ranging from 0.48–0.75. CONCLUSIONS: Braden scale is not a reliable tool to be used in the intensive care unit, and we do not recommend the use of this scale to assess the risk of developing pressure injury.
