ABSTRACT
BACKGROUND AND AIMS: High-resolution anorectal manometry (HRM) is associated with significant patient and parent anxiety, which can impact the success and efficiency of the procedure. The nature of HRM necessitates cooperation of an alert child. This study examined effects of psychoeducation intervention on decreasing procedural distress in both pediatric patients and their parents. METHODS: A prospective randomized study of children aged 3-12 years, undergoing HRM, was performed utilizing child-centric educational video. Patients received either psychological preparation intervention or treatment-as-usual. Distress was assessed through self-reported and parent-reported anxiety measures (STAIC-S; STAI-S), physiological arousal measurements, and an observational scale of procedural distress (PBCL). RESULTS: A total of 63 children, aged 3-12 yrs (6.7 ± 2.5), completed the study. Measures of observed and reported distress and anxiety (PBCL; STAIC-S) were significantly less in children receiving intervention. Parents of children in the intervention group also reported significantly less preprocedural anxiety (STAI-S). Effects on physiological arousal were mixed, with significant preprocedural decrease in systolic blood pressure but no difference in heart rate from baseline. CONCLUSIONS: Preprocedural psychological preparation was effective in decreasing pediatric patient and parental self-reported anxiety associated with HRM. Intervention decreased physician time necessary to successfully complete the study and significantly decreased the number of times patients had to endure balloon inflation.
