Chronic kidney disease (CKD) is the chronic, progressive and irreversible loss of kidney functions associated with many causes and consists of a total of five clinical stages that require different treatment and care. The fifth of these stages is called end-stage renal disease (ESRD), and hemodialysis (HD) is offered to patients as a renal replacement treatment option unless a successful kidney transplantation occurs at this stage. Although HD treatment is a treatment option that aims to reduce mortality and morbidity rates and improve quality of life, it can also bring about different problems caused by the disease and treatment. Many physical and psychological symptoms are observed in patients receiving HD treatment, such as pain, fatigue, dyspnea, sleep problems, restless legs syndrome, itching, muscle cramps, nausea-vomiting, loss of appetite, constipation, dry skin, sexual dysfunction, anxiety, depression, and delirium. In addition, these symptoms bring about social and economic problems and negatively affect the patient's quality of life. In patients with ESRD and receiving HD treatment; The most common symptom is pain due to reasons such as accumulation of fluid and metabolic wastes, comorbid causes such as diabetes, cardiovascular and pulmonary diseases, infections, changes in the musculoskeletal system, HD procedure, carpal tunnel syndrome, and anxiety. It is known that hemodialysis patients experience moderate to severe pain, and unless the pain they experience is eliminated, the quality of life of individuals and their motivation for the continuity of treatment are negatively affected. Therefore, the importance of pain management in these patients increases considerably. The essence of effective pain management is a multidisciplinary approach and the combined use of pharmacological and non-pharmacological methods. When the studies are examined, it is seen that pharmacological and/or complementary and integrative treatment (TIT) methods are used in the management of pain in patients receiving HD treatment. In pharmacological treatment, non-opioid analgesics such as acetaminophen, topical analgesics, gabapentinoids and tricyclic antidepressants are primarily preferred. However, patients' inability to fully express their pain, their unwillingness to increase the already existing medication load, fear of addiction or side effects of the medications to be used, ethnic or cultural factors, healthcare professionals' inability to adequately evaluate pain and lack of training in pain management are among the reasons for HD patients. There are difficulties in pain management due to reasons such as the lack of a guide on pain management. For this reason, patients prefer TIT methods such as yoga, reflexology, music therapy, relaxation exercises, aromatherapy, acupressure and Reiki instead of drug treatment.

Reiki, one of the energy-based treatments that has attracted great attention from nurses among TIT methods in recent years; It provides physical, mental and emotional healing by balancing the disrupted energy flow.

While only two studies examining the effect of Reiki on pain in patients receiving HD treatment have been found in the literature, no studies investigating its effect on quality of life have been found. Reiki is a method that can be easily learned, is non-invasive, does not require special equipment, is cost-free, easy to apply, reduces the use of analgesics and has no side effects. In addition, when applied together with standard treatment, it stands out as one of the different approaches that nurses can offer to the patient in providing pain management, as it increases the quality of life by reducing the severity of pain. Based on this point, the doctoral thesis titled "The Effect of Reiki Application on Pain Intensity and Quality of Life in Patients Receiving Hemodialysis Treatment" has a mixed design; It was conducted as a pretest-posttest, double-blind, randomized controlled study and a qualitative study with individual in-depth interviews. In the study data, it was observed that first level Reiki, applied for a total of 12 sessions for 30 minutes three times a week in the first three hours of HD, reduced the severity of pain, improved mental health, and positively affected the quality of life by reducing the symptoms and problems of kidney disease. The fact that first level Reiki application takes a long time puts pressure on the practitioner, considering the other workloads of nurse practitioners, and a limited number of patients can benefit from this application.There is also a second level (distance) Reiki application in the literature that has been applied to different patient groups and examines the effect of Reiki on pain intensity. In addition, no study has been found in the literature examining the effect of second-level Reiki on pain intensity and quality of life in HD patients, nor has there been any study examining how long the effect of Reiki application lasts. Therefore, this study aims to determine the effect of 20-minute second-level Reiki application for 4 consecutive days on pain intensity and quality of life in patients receiving HD treatment and to compare the follow-up results of first-level Reiki and second-level Reiki applications.
