Analysis of an intervention to reduce parental anxiety prior to voiding cystourethrogram

PurposeThe voiding cystourethrogram (VCUG) is a common imaging test in pediatric urology that can be associated with anxiety in the child and parent. We hypothesized that education by mailed brochure would decrease pre-procedure parental anxiety.MethodsFamilies of children scheduled for VCUG were randomized into an experimental group that was mailed an educational brochure about the VCUG and a control group. Immediately prior to the procedure, parental anxiety was assessed with the self-administered State-Trait Anxiety Inventory (STAI). The parent repeated the STAI at home after the VCUG and answered brief questions about educational resources used to prepare for the VUCG.ResultsWe enrolled 105 families (47 experimental, 58 control). Parental state anxiety was higher before the procedure than after the procedure (p < 0.001). Younger parents had greater pre-procedure state anxiety (p = 0.007). Contrary to our expectations, pre-procedure state anxiety did not differ between control and experimental groups. However, parents in the experimental group demonstrated less anxiety with some individual items in the questionnaire.ConclusionAn educational brochure mailed to families prior to VCUG did not decrease pre-procedure parental state anxiety. However, the educational brochure can ensure accurate dissemination of information to help families prepare for this potentially distressing procedure.
