Abstract
Objective: The purpose of this study was to: observe the value of the score of Braden Q scale in predicting the pressure ulcer in pediatric ICU patients in China; determine the critical cutoff point for classifying patient risk; and describe the pressure ulcer incidence. Methods: A prospective cohort descriptive study with a convenience sample of 198 patients on bedrest for at least 24 hours without pre-existing pressure ulcers were enrolled from a pediatric intensive care unit (PICU). The Braden Q score and skin assessment were independently rated and data collectors were blind to the other measurer. Patients were observed up to 3 times per week for 2 weeks and then once a week until PICU discharge. Results: Fourteen patients (7.1%) developed pressure ulcers; 12 (85.7%) were Stage I pressure ulcers, 2 (14.3%) were Stage II pressure ulcers, and there were no Stage III of 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 is 0.543~0.612. Conclusions: The PICU patients are susceptible to the pressure ulcer. The value of the Braden Q Scale in Chinese pediatric population is relatively poor, it should be optimized when used in Chinese pediatric patients.
