Importance  Effective methods to reduce children’s preoperative anxiety (such as giving information beforehand, organizing a tour of the operating room [OR] before the intervention, and incorporating clown physicians) may be difficult to implement for some hospitals, as they are time-consuming and expensive and require hospital staff to be performed.

Objective  To test the effectiveness of Clickamico, an app that shows clown physicians giving a comical and informative tour of the OR, for reducing preoperative anxiety in children.

Design, Setting, and Participants  This unblinded randomized clinical trial included 40 children aged 6 to 11 years undergoing a planned surgical intervention at a third-level Italian pediatric hospital from December 2013 to September 2014 randomized into experimental (n = 20) and control (n = 20) groups.

Interventions  The experimental intervention was a 6-minute video showing 2 clown physicians visiting the OR and explaining to each other what is in the OR in a joking way. The video was shown on a tablet to children in the experimental group the afternoon preceding a planned surgical procedure. The control intervention was the standard informative intervention regarding the surgical procedure the next day.

Main Outcomes and Measures  The main outcome was preoperative anxiety. Preoperative anxiety was measured before the experimental and control interventions and immediately before entering the OR using the modified Yale Preoperative Anxiety Scale (m-YPAS).

Results  The experimental and control groups were homogeneous with regard to age (mean [SD] age, 8.8 [2.5] vs 8.6 [2.2] years), sex (female, 11 [55.0%] vs 9 [45.0%]), parents’ age (mean [SD] age, 41.8 [6.2] vs 41.3 [5.0] years), and previous surgical procedures (already underwent surgical procedure, 9 [45.0%] vs 10 [50.0%]). The initial mean (SD) m-YPAS scores were 37.3 (21.7) and 37.1 (13.8) for the experimental and control groups, respectively; the mean (SD) m-YPAS scores when entering the OR were 33.0 (18.4) and 48.6 (15.9), respectively (P = .009). The mean (SD) difference between the m-YPAS score at the first and second measurements of each participant was −2.8 (7.2) in the experimental group and 10.7 (10.8) in the control group. The 13.5-point difference between these averages was statistically significant (P = .003).

Conclusions and Relevance  The app was effective in reducing preoperative anxiety in Italian children admitted to an Italian National Health System pediatric hospital and may act as a substitute for staff-provided interventions, allowing possible reductions of hospital costs.

Clickamico (Buddyclick)

Two clown physicians (Dr Cloud and Dr Wisp) take a tour of one of the operating rooms at Meyer Children's Hospital. During the tour, they make jokes and perform gags, explaining to each other in a playful and funny—although technically correct—way what an operating room is like and the objects and situations that can be found there.
