Summary

The purpose of this study is to evaluate the effectiveness and cost-effectiveness of group robot therapy with the PARO therapy robot in terms of quality of life and neuropsychiatric symptoms in people living with dementia in residential centers. In addition, the acceptability of the robot on the part of the users participating in the study will be evaluated. The evaluation will be carried out through a multicenter pragmatic clinical trial randomized to an intervention group (PARO therapy robot) or a control group (treatment as usual). Participants in the intervention group will complete three sessions per week with the PARO therapy robot during 12 weeks. Participants in the control group will maintain their standard care. In addition, a follow-up evaluation will be made three months after the end of the intervention to assess the duration of the possible effects.

Detailed description

The increase in life expectancy in recent decades has been associated with inevitable aging of the population and a rise in the prevalence of dementia. The World Health Organization (WHO) defines dementia as an acquired condition involving multiple cognitive disabilities that are sufficient to interfere with the daily life of the patients and their environment, with important associated personal suffering and economic costs. Despite advances in recent years, the diagnosis and course of dementia remains a challenge for professionals, and there continue to be important social and healthcare shortcomings regarding prevention, treatment and care. Due to the deficiencies of the existing drugs, non-pharmacological therapies (NPT) are particularly relevant in the management of dementia. A NPT is any non-chemical, theoretically supported, focused and replicable intervention that is potentially able to produce a relevant benefit. Among these NPT, mention must be made of robot therapy, which involves the use of robots that simulate animals and are equipped with artificial intelligence and multiple sensors that allow them to behave and interact with users as if they were a real animal. Therapy robots are regarded as an alternative to animal-assisted therapy, avoiding complications arising from the presence of animals while affording similar effects. The Personal Assistant Robot (PARO) robot seal was developed with this purpose in mind. It is the most widely used robot in the field of dementia, and also the most widely studied robot. Designed in Japan by Professor T. Shibata, PARO is an interactive robot with five types of sensors (light, touch, posture, temperature and sound), and it has demonstrated the ability to provide social and emotional stimulation. In people living with dementia, robot therapy has been shown to offer psychological benefits (improved relaxation and motivation), physiological benefits (improved vital signs) and social benefits (stimulation of communication). In addition, the most recent studies have shown robot therapy to exert positive effects upon cognitive function, agitation, anxiety, depression, other neuropsychiatric symptoms and quality of life. However, other reviews have not recorded sufficient evidence of the positive effects of robot therapy upon cognition, neuropsychiatric symptoms or quality of life. Further quality studies are therefore needed on the effect of robot therapy in people living with dementia. In this regard, the proposed study is aimed at evaluating the effectiveness and cost-effectiveness of group robot therapy intervention with the PARO robot in terms of quality of life and neuropsychiatric symptoms in people living with dementia in residential centers. In addition, the acceptability of the intervention on the part of the users participating in the study will be evaluated. For this purpose, a multicenter study will be carried out in the form of a randomized clinical trial in which the selected participants will be randomized to an intervention group (PARO Therapy Robot) or a control group (standard care). Hypothesis: * After the intervention, participants in the experimental group will improve their quality of life scores compared with the control group receiving standard care, where scores will be maintained or will get worse. * Participants in the experimental group will have fewer neuropsychiatric alterations than participants in the control group. * Participants in the experimental group will reduce their depression scores versus participants in the control group. * Participants in the experimental group will experience less agitation than participants in the control group. * Participants in the experimental group will experience less apathy than participants in the control group. * The PARO robot will be well accepted by the individuals living with dementia. * PARO Therapy Robot will be efficient in comparison with standard care. Objectives The primary study objective is: • To compare the effectiveness of the PARO Therapy Robot and standard care in improving the quality of life of people with dementia living in residential centers. The secondary objectives are: * To compare the effectiveness of the PARO Therapy Robot and standard care in reducing neuropsychiatric disorders in people with dementia. Specifically, efficacy will be compared in terms of: * Reducing depressive symptoms. * Reducing agitation. * Reducing apathy. * To evaluate the acceptability of the PARO robot on the part of the patients. * To perform a cost-effectiveness and cost-utility analysis, comparing the direct costs of the PARO Therapy Robot and standard care with the results afforded by the two alternatives.

Interventions

Type	Name	Description
BEHAVIORAL	PARO Therapy Robot	Participants allocated to the PARO Therapy Robot group will receive three group robot therapy sessions per week for 12 weeks, in addition to continuing their standard care. Robot therapy session will last 20 minutes. The sessions will be partially guided, intending to allow participants to interact with the robot seal freely for as long as possible, but redirecting the activity if necessary. The sessions will be conducted in group format, in groups of 4 users, with participants sitting in a circle around a table. The professional conducting the sessions will be a therapist with experience in NPT for people living with dementia, and who has attended the training session on the study intervention protocol. The sessions will be structured as follows: 1. Welcome and presentation. 2. Main activity with PARO. 3. PARO cleaning. 4. End of session. A total of 13 different sessions are proposed, to be conducted in a cyclical manner (each session 3 times, except sessions 1 and 2).
