Purpose: This study was planned to examine the effects of virtual reality glasses and breathing exercise applications on symptoms and quality of life in patients receiving hemodialysis treatment.
Design: This randomized controlled cross-sectional study will be applied to individuals diagnosed with End-Stage Renal Disease (ESRD) who were treated in hemodialysis units of 3 state hospitals and 2 private hospitals. No randomized controlled study was found using scales on patients diagnosed with ESRD in the literature review. Power analysis was performed using the G\*Power (v3.1.7) program to determine the sample size. It was decided that there should be 53 people in the groups for 80% power at α=0.05 level.
People over the age of 18, diagnosed with end-stage renal disease, on hemodialysis for the last 3 months, without communication barriers and volunteering to participate in the study will be included in the study according to the randomization table.
The data will be filled with a questionnaire form containing demographic data, the Dialysis Symptom Index (DSI) and the World Health Organization Quality of Life Scale Short Form Turkish Version (WHOQOL-Bref-TR). Necessary permissions have been obtained from the people who developed the scales.
Patients who meet the research criteria will be assigned to experiment 1 (virtual reality glasses), experiment 2 (breathing exercise) and control groups according to the randomization table. Then;
1. Experiment 1 Group 1st Application: After the patients who agree to participate in the study sign the informed consent form, the demographic characteristics of the patients, the DSI and WHOQOL-Bref-TR scales will be filled in by the researcher. The patients will watch a simulation consisting of forest and nature images with virtual reality glasses for a total of 20 minutes before and after hemodialysis.
In the 2nd and 3rd Applications, the patients will watch the same simulation at one-week intervals and then the DSI and WHOQOL-Bref-TR will be filled in.
2. Experiment 2 Group:
The researcher will demonstrate deep breathing exercises in a specific order and have the individuals apply the exercises one-on-one.
Procedure steps:
1. Normal breathing for 1 minute,
2. Chest breathing 20-24 times (approximately 3 minutes),
3. Diaphragmatic breathing (inhale through the nose and exhale through the nose) 20-24 times (approximately 3 minutes),
4. Pursed lip breathing 16-20 times (approximately 2 minutes) (inhale through the nose and exhale through the mouth),
5. Normal breathing for 1 minute
1\. Application: After the patients who agree to participate in the study sign the informed consent form, the demographic characteristics of the patients, DSI and WHOQOL-Bref-TR scales will be filled out by the researcher. The patients will be applied a total of 10 minutes of exercises before and after hemodialysis.
In the 2nd and 3rd applications, the patients will be subjected to the same breathing exercise one week apart and then the DSI and WHOQOL-Bref-TR will be filled in.
3rd Control Group:
1. st Application: After the informed consent form is signed by the patients who agree to participate in the study, the demographic characteristics of the patients, the DSI and WHOQOL-Bref-TR scales will be filled in by the researcher. No procedure will be applied, they will receive routine hemodialysis treatment.
2. nd and 3rd Applications will be performed one week apart and the DSI and WHOQOL-Bref-TR will be filled in after the hemodialysis treatment without any procedure.
Statistics: SPSS Statistical Software program will be used for statistical analyses. While evaluating the study data, descriptive statistical methods (Mean, Standard deviation, median, frequency, ratio) as well as the Shapiro Wilk test and box plot graphics will be used for the normal distribution of the variables.
In the comparison of variables showing normal distribution between groups, ANOVA, Kruskal-Wallis H test, Tukey's post-hoc test, Pearson's chi-square test, Fisher's exact chi-square test, Bonferroni test, and multiple regression model analyses. Significance will be evaluated at p\<0.05 level.
