The Cost-Effectiveness of Using PARO, a Therapeutic Robotic Seal, to Reduce Agitation and Medication Use in Dementia: Findings from a Cluster-Randomized Controlled Trial

The plush toy used in this study offered marginally greater value for money than PARO in improving agitation. However, these costs are much lower than values estimated for psychosocial group activities and sensory interventions, suggesting that both a plush toy and the PARO are cost-effective psychosocial treatment options for agitation.
