Objective: The purpose of this study was to: ( 1 ) observe the value of the score of Braden Q scale in predicting pressure ulcers in pediatric Intensive Care Unit ( ICU) patients in China, ( 2) determine the critical cutoff point for classifying patient risk, and ( 3) describe the pressure ulcer incidence. Methods: A prospective cohort descriptive study with a convenience sample of 198 patients bed-ridden for at least 24 hours without pre-existing pressure ulcers enrolled from a pediatric intensive care unit ( PICU) . The Braden Q score and skin assessment were independently rated, and data collectors were blinded to the other measures. Patients were observed for up to 3 times per week for 2 weeks and once a week thereafter until PICU discharge. Results: Fourteen patients ( 7. 1%) developed pressure ulcers; 12 ( 85. 7%) were Stage I pres-sure ulcers, 2 ( 14. 3%) were Stage II, and there were no Stage III or IV pressure ulcers. Most pressure ulcers ( 64. 3%) were present at the first observation. The Braden Q Scale has an overall cumulative variance contribution rate of 69. 599%. Using Stage I+ pressure ulcer data obtained during the first observation, a Receiver Operator Characteristic ( ROC) curve for each possible score of the Braden Q Scale was constructed. The area under the curve ( AUC) was 0. 57, and the 95% confidence interval was 0. 50-0. 62. At a cutoff score of 19, the sensitivity was 0. 71, and the specificity was 0. 53. The AUC of each item of the Braden Q Scale was 0. 543-0. 612. Conclusions: PICU patients are susceptible to pressure ulcers. The value of the Braden Q Scale in the studied pediatric population was relatively poor, and it should be optimized before it is used in Chinese pediatric patients.
