Effects of Robotic Cat and Betta Fish Therapies in Hemodialysis Patients

The research was carried out as a randomized controlled trial to examine the physiological and psychological effects of robotic cat and Betta fish therapies in hemodialysis patients.

Along with the benefit of hemodialysis treatment, patients develop physical and psychosocial problems and symptoms associated with hemodialysis. Undesirable symptoms experienced by patients undergoing hemodialysis include hypotension/hypertension, respiratory distress, headache, back-chest pain, muscle cramps, nausea-vomiting, fatigue, fever, constipation, diarrhea, itching. In addition to negative feelings such as anger, anxiety, unhappiness and fear associated with hemodialysis, patients often experience adjustment disorder, anxiety, depression and sleep disorders, and may experience social isolation and loneliness with the fear of being a burden to their friends or family members. The physical symptoms that patients receiving hemodialysis treatment have to cope with and psychological symptoms such as unhappiness and loneliness make it difficult to adapt to their disease and contribute to an increase in mortality.

Today, "pet therapy" is used for treatment in many hospitals, psychiatry clinics, nursing homes and rehabilitation centers. Pet therapy is an application in the Nursing Interventions Classification. In studies with different animals on different populations in health services, hospitals, psychiatry clinics, nursing homes and rehabilitation centers, pet therapy; It is stated that it has physiological and psychological benefits such as decrease in psychiatric signs and symptoms, increase in cardiovascular system functionality, increase in socialization skills and individual self-management. It is reported that the physiological and psychological benefits of pet therapy applications have been proven in many of the studies using many animals (such as birds, dogs, cats, fish) and robot simulations. It has been reported that robotic pet therapy reduces depression, agitated behaviors, pain, stress hormone levels and loneliness, increases heart rate, happiness, and quality of life. Again, it is stated that even a simple movement of live animals reduces loneliness, anxiety, depression and social isolation in humans.

It has been determined that an unpublished experimental doctoral thesis study, of which a poster statement can be reached, was conducted abroad on the effect of "the effect of pet therapy with live dogs on depression" in patients with CRF. Again, one pilot study and one pre-test-post-test study were found in which the effect of pet therapy on happiness with a live dog was examined. In Turkey, no study was found with pet therapy in patients undergoing CRF and hemodialysis. However, there is limited information in the literature about the benefits of human-fish interactions related to pet therapy. It has been reported that ornamental betta fish increase individual self-management, and reduce anxiety and stress. In a systematic review, it was reported that various fish species reduced anxiety, physiological stress, anxiety and pain, provided relaxation, improved food intake, had positive benefits on mood and body weight (weight gain), but no information was found about loneliness.

About the subject, only pet therapy with live dogs was used in hemodialysis patients, and no experimental study was found. In addition, it was determined that there was no information about the effect of Betta fish therapy on loneliness and that happiness, dialysis symptoms, compliance with ESRD, and body mass index (BMI) were not examined before in patients undergoing hemodialysis. The fact that the mentioned parameters were not examined indicates that there is a lack of evaluation of robotic cat or Betta fish therapies. In line with this information, the aim of this study was to examine the positive physiological (dialysis symptoms, BMI) and psychological (dialysis symptoms, happiness, loneliness, adaptation to ESRD) effects of robotic cat and Betta fish therapies in patients undergoing hemodialysis.
