The Braden Scale for Predicting Pressure Sore Risk.
Bergstrom N, Braden BJ, Laguzza A, Holman V.
The Braden Scale for Predicting Pressure Sore Risk was developed to foster early
identification of patients at risk for forming pressure sores. The scale is
composed of six subscales that reflect sensory perception, skin moisture,
activity, mobility, friction and shear, and nutritional status. Content and
construct validity were established by expert opinion and empirical testing.
Three studies of reliability are reported here, using raters who varied in level
of educational preparation and geographic region. Two prospective studies of
predictive validity were completed to determine the scale's sensitivity and
specificity. Reliability ranged from r = .83 to r = .94 for nurses' aides and
licensed practical nurses; when used by registered nurses, the reliability
increased to r = .99. Predictive validity was calculated for each cut-off point
of the scale. Using a cut-off point of 16, sensitivity was 100% in both studies.
Specificity ranged from 64% to 90%. This instrument has highly satisfactory
reliability when used by RNs, and greater sensitivity and specificity than
instruments previously reported.
