Effects of therapeutic play on children undergoing cast-removal procedures: a randomised controlled trial

OBJECTIVES: To examine (1) the effectiveness of therapeutic play in reducing anxiety and negative emotional manifestations among children undergoing cast-removal procedures and (2) the satisfaction of parents and cast technicians with cast-removal procedures. DESIGN: A randomised controlled trial. SETTING: An orthopaedic outpatient department of a regional teaching hospital in Hong Kong. PARTICIPANTS: Children (n=208) aged 3–12 undergoing cast-removal procedure were invited to participate. INTERVENTIONS: Eligible children were randomly allocated to either the intervention (n=103) or control group (n=105) and stratified by the two age groups (3–7 and 8–12 years). The intervention group received therapeutic play intervention, whereas the control group received standard care only. Participants were assessed on three occasions: before, during and after completion of the cast-removal procedure. OUTCOME MEASURES: Children’s anxiety level, emotional manifestation and heart rate. The satisfaction ratings of parents and cast technicians with respect to therapeutic play intervention were also examined. RESULTS: Findings suggested that therapeutic play assists children aged 3–7 to reduce anxiety levels with mean differences between the intervention and control group was −20.1 (95% CI −35.3 to −4.9; p=0.01). Overall, children (aged 3–7 and 8–12) in the intervention groups exhibited fewer negative emotional manifestations than the control group with a mean score difference −2.2 (95% CI −3.1 to −1.4; p<0.001). Parents and technicians in the intervention group also reported a higher level of satisfaction with the procedures than the control group with a mean score difference of 4.0 (95% CI −5.6 to 2.3; p<0.001) and 2.6 (95% CI 3.7 to 1.6; p<0.001), respectively. CONCLUSION: Therapeutic play effectively reduces anxiety and negative emotional manifestations among children undergoing cast-removal procedures. The findings highlight the importance of integrating therapeutic play into standard care, in particular for children in younger age. TRIAL REGISTRATION NUMBER: ChiCTR-IOR-15006822; Pre-results.
