Study ObjectiveTo evaluate the effectiveness of a behavioral preparation program on reducing anxiety in children and their parents prior to elective surgery.DesignCross-sectional study.SettingA children's hospital.Patients143 children undergoing outpatient surgery, and their parents.InterventionsA behavioral preoperative preparation program.Measurements And ResultsOverall anxiety in children and their parents did not differ significantly between the group that received the preoperative program and the group that did not (p = NS). Children older than 6 years were least anxious on separation from their parents if they participated in the preparation program more than 5 to 7 days prior to surgery, moderately anxious if they did not receive preparation, and most anxious if they received the preparation 1 day prior to surgery (P = 0.04). Multivariable regression analysis (for overall model, F = 2.14, p = 0.02) revealed that although the preparation program itself was not a predictor of a child's behavior on separation to the operating room, the interaction between child's age and timing of the program (p = 0.003), and child's previous hospitalization were predictors of children's anxiety response. Similarly, in the preoperative holding area, independent predictors of anxiety included timing of the preparation program, age of child, and the child's baseline temperament characteristics.ConclusionsThe results highlight the complexities in assuming that a behavior-based preoperative preparation program is effective for all pediatric outpatients. The effects of such an intervention vary with the child's age, the timing of the intervention, and a history of previous hospitalization.
