Value of the Waterlow stress injury scale and Braden stress scale in predicting the prevention of pressure ulcer in ICU patients

Objective To explore the value of the Waterlow pressure injury scale and Braden stress scale in predicting the prevention of pressure ucler in ICU.

Methods The Waterlow scale and Braten scale were used to predict the pressure ulcers of 724 patients, the predictive value of two scales were compared with the final pressure ulcers, and the predictive value of two scales were analyzed.

Results The true positive in 44 cases and true negative in 600 cases were identified using the Waterlow rating scale, and the sensitivity and specificity of which were 100.00% and 88.23%, respectively.The true positive in 44 cases and true negative in 178 cases were identified using the Braden rating scale, and the sensitivity and specificity of which were 100.00% and 73.82%, respectively.The specificity and negative predictive value of Waterlow rating scale were significantly higher than those of Braden rating scale(P < 0.01), and the differences of the sensitivity and positive predictive value bewteen the two scales were not statistically significant(P>0.05).The area under the Waterlow rating scale curve(0.770) was slightly higher than that of Braten rating scale curve(0.704) (P < 0.05).

Conclusions During the process of pressure ulcer prevention in ICU patients, the specificity of Waterlow rating scale is better than that of Braden rating scale.In clinical practice, the nursing staff should take specific nursing measures according to the scale.
