A non-experimental prospective study was done to analyse the validity of the three scales: the Braden scale, the Song and Choi scale and the Cubbin and Jackson scale to assess the patients at a university hospital SICU.
The Cubbin and Jackson scale is an instrument developed to assess the pressure ulcer risk of patients in the ICU.
The cut-off points suitable for three scales of SICU patients was given along with the sensitivity, specificity, PVP and PVN as follows: the Braden scale (cut-off 14), the Song and Choi scale (cut-off 21) and the Cubbin and Jackson scale (cut-off 28) (Table 2).
The value for the Braden scale was 0.881, the value for the Song and Choi scale was 0.890 and the value for the Cubbin and Jackson scale was 0.902.
Other studies using the Cubbin and Jackson scale have recommended cut-off points between 24 and 29 (Jun et al 2004; Boyle and Green 2001; Kim 1997; Lowery 1995).
