Background: Blood pressure (BP) is routinely measured while triaging children presenting to the pediatric emergency department (PED).

Objectives: To determine whether a medical clown shortens the time to acquire a BP measurement among children undergoing triage in the PED.

Methods: The study comprised 133 children. Patients were assigned to one of two groups: with a medical clown or without a medical clown.

Results: The presence of a medical clown led to a significantly shorter time to acquire a blood pressure measurement (60 ± 23 seconds vs. 81 ± 43.5 seconds, P < 0.001. Clowns had a significant effect on shortening total triage length among children of Jewish ethnicity compared to Arab ethnicity (113 ± 353.6 seconds vs. 154 ± 418 seconds, P = 0.012).

Conclusions: Using medical clowns while measuring BP during triage when used in a culturally appropriate manner shortens time.

Background: A good physical exam is necessary to help pediatricians make the correct diagnosis and can save unnecessary imaging or invasive procedures. Distraction by medical clowns may create the optimal conditions for a proper physical examination.

Methods: Children aged 2–6 years who required physical examination in the pediatric emergency department were recruited and randomly assigned to one of two groups: physical exam by a pediatrician in the presence of caregivers vs. physical exam with the assistance of a medical clown. Outcome measures consisted of the level of child's discomfort, anxiety, and the quality of the physical examination.

Results: Ninety three children participated. Mean age was 3.3 ± 3.6 years (range 2–6). The duration of the physical exam was similar between the clown and control groups (4.6 ± 1.4 minutes vs. 4.5 ± 1.1 minutes (P = 0.64). The duration of discomfort was shorter in the clown group (0.2 ± 0.6 minutes) than the control group(1.6 ± 2.0 minutes, P = 0.001). In the medical clown group, 94% of pediatricians reported that the medical clown improved their ability to perform a complete physical examination. A trend of less hospitalization in the medical clown group was also noticed (11.3% in the medical clown group vs. 18.3% in the control group, P = 0.1); however, further study is required to verify this observation.

Conclusions: Integration of a medical clown in physical examination improves the overall experience of the child and the caregivers and helps the pediatrician to perform a complete physical examination.

Background: Medical clowns are increasingly used for diminishing pain and anxiety during painful procedures being performed on children in the hospital setting. Cortisol levels rise as a response to emotional distress. 

Objectives: To investigate whether medical clown-assisted interventions to reduce child's distress during venipuncture have an effect on cortisol levels. 

Methods: During a 1 year period, children requiring blood work or intravenous access in the pediatric emergency department were prospectively randomized to either the presence or absence of a medical clown during the procedure. The child's distress was evaluated using the Faces Pain Scale - revised (FPS-R) for the 4–7 year age group and the visual analog scales (VAS) for those aged 8–15 years. Serum cortisol levels were measured in blood samples obtained by venipuncture. 

Results: Fifty-three children aged 2–15 years were randomly assigned to the study group (with medical clown, n=29) or to the control group (without medical clown, n=24). Combined pain scores of the study group and control group were 2.2 and 7.5 respectively (P < 0.001). No difference in mean cortisol levels was found between the study group and the control group at all ages (16.4 µg/dl vs. 18.3 µg/dl, P = 0.65).

Conclusions: In this pilot study, medical clowns reduced the distress from venipuncture in children. No effect on cortisol levels was observed. 

Background: Intra-articular corticosteroid injection (IACI), a common procedure in juvenile idiopathic arthritis, is usually associated with anxiety and pain. In a previous study, we concluded that nitrous oxide (NO₂) provides effective and safe sedation for such procedures. Following the introduction of medical clowns in our hospital, we added them as an integral part of the team performing IACI.

Objectives: To prospectively evaluate the effect of a medical clown on pain perception during intra-articular corticosteroid injection for juvenile idiopathic arthritis using NO₂ conscious sedation.

Methods: Patients scheduled for IACI first met and interacted with the medical clown. During the procedure, the rheumatologist and the medical clown worked in parallel to create distraction. NO₂ was administered. The patient, parent, physician, medical clown and nurse completed a visual analog scale (0–10) for pain. Change in heart rate ≥ 15% was recorded to evaluate physiologic response to pain and stress.

Results: A total of 46 procedures were performed in 32 children: 23 girls, 9 boys, with a mean age of 10.9 ± 3.6 years. The median visual analog scale pain score for the patients, parents, physicians, medical clown and nurses was 2, 2, 1, 1 and 1, respectively. Five patients had increased heart rate and experienced increased pain.

Conclusions: Active participation of a medical clown during IACI with nitrous oxide for juvenile idiopathic arthritis further decreases pain and stress and results in a positive patient experience.
