This report examines the effectiveness of two interventions for dementia patients: pet therapy and the PARO robot. It analyzes the benefits and drawbacks of each, considering factors like patient mood, anxiety reduction, and social interaction. The report highlights the limitations of pet therapy, such as potential allergic reactions, injury risks, and higher costs, while emphasizing the advantages of PARO robots, including disease-free interaction, reduced care needs, and controlled behavior. The report suggests that healthcare facilities implement PARO robots based on NHMRC clinical guidelines and provides ethical considerations, emphasizing patient autonomy, beneficence, non-maleficence, and justice. Additionally, the report offers suggestions for integrating PARO robots into care processes, including staff training, public awareness campaigns, patient consent, and family-centered care. The report concludes that PARO robot implementation is a more viable and ethical approach to improving the quality of life for dementia patients.
