Abstract
BACKGROUND: Animal-assisted activities (AAAs) have long been present in pediatric oncology as a nonpharmacological intervention aimed at helping children cope with symptoms and negative emotions during hospitalization and antineoplastic treatment. Among the systematic reviews in the literature, there is a lack of one with meta-analysis that includes only RCTs centered on the effect of the intervention on symptoms and emotions in children with neoplastic disease.
OBJECTIVE: To synthesize the effect of AAAs on symptoms and emotions of children with neoplastic disease.
METHODS: Studies were searched from biomedical databases, trial registries, and web resources. The risk of bias of included studies was assessed with RoB 2, and the overall effect size of the intervention was calculated by creating random-effects meta-analyses graphically represented by forest plots. The summary of findings was illustrated with a table in accordance with the GRADE method.
RESULTS: Three parallel-group randomized controlled trials with low risk of bias were included (N = 151, mean age: 8.5-11.2 years). AAAs are promising for anxiety reduction (N = 134; SMD = -0.07 [95% CI: -0.40, 0.27], p > 0.05) and quality of life improvement (N = 84; SMD = -0.11 [95% CI: -0.53, 0.31], p > 0.05) in children and for anxiety reduction (N = 154; SMD = -0.50 [95% CI: -1.52, 0.52], p > 0.05) in parents/caregivers. The certainty/quality of evidence is low to very low.
CONCLUSIONS: The effect of animal-assisted activities to reduce anxiety and improve the quality of life of children with neoplastic disease and to reduce the anxiety of parents/caregivers is promising. However, more studies need to be conducted on the topic that overcome the important methodological limitations manifested by current research in order to collect more data in favor of implementing the intervention in pediatric oncology.
