The study was planned to evaluate the effects of discharge training on PEG use given to palliative care patients' relatives on the caregiver burden and quality of life of the relatives. The main questions that the study aims to answer are as follows: * How does PEG training given before discharge affect the knowledge level of caregivers on PEG use? * How does PEG training given before discharge affect the caregiver burden? * How does PEG training given before discharge affect the caregiver's caregiver stress? * How does PEG training given before discharge affect the quality of life of the caregivers? The researchers will compare the PEG training given before discharge with a control group that did not receive training in this regard in order to evaluate the effects of PEG training given before discharge on the caregiver burden, caregiver stress and quality of life of the caregivers. The study will use a general information form, the Caregiver Burden Scale, the Caregiver Stress Index Form, the SF 36 Quality of Life Scale, and the Percutaneous Endoscopic Gastrostomy Tube Nutrition Information Scale for Caregivers. Participants: * Face-to-face interviews will be conducted with caregivers at 0, 1, and 3 months. * The forms used in the study will be filled out at each interview. * The intervention group will be trained only at the first interview.
