AIMS: Paediatric pressure ulcers are a serious problem to healthcare service.
Thus, effective and early identification of the risk of developing pressure
ulcer is essential. The Braden Q scale is a widely used tool in the risk
assessment of paediatric pressure ulcer, but its predictive power is
controversial. Hence, we performed a meta-analysis to evaluate the predictive
power of the Braden Q scale for pressure ulcer in hospitalised children and
offer recommendations for clinical decision.
METHODS: Studies that evaluated the predictive power of the Braden Q scale were
searched through databases in English and Chinese, including Medline, Cochrane
Library, Embase, CINAHL, SinoMed, CNKI, Wangfang and VIP. The studies were
screened by two independent reviewers. QUADAS-2 was used to assess the risk of
bias of eligible studies. Demographic data and predictive value indices were
extracted. The pooled sensitivity, specificity and receiver operating
characteristics (ROC) were calculated by MetaDiSc 1.4 using random-effects
models.
RESULTS: Cochran Q = 26.13 (P = 0.0036) indicated the existence of
heterogeneity; the I2 for pooled DOR was 61.7%, suggesting significant
heterogeneity among the included studies. The pooled sensitivity and specificity
were 0.73 (95% CI: 0.67-0.78) and 0.61 (95% CI: 0. 59-0.63), respectively,
yielding a combined DOR of 3.47 (95% CI: 2-6.01). The area under the ROC curve
was 0.7078 ± 0.0421, and the overall diagnostic accuracy (Q*) was
0.6591 ± 0.0337. Sensitivity analysis showed the results were robust.
CONCLUSION: The Braden Q scale has moderate predictive validity with medium
sensitivity and low specificity for pressure ulcers in hospitalised children.
Further development and modification of this tool for use in paediatric
population are warranted.
