The purpose of the study will be explained to the individuals in the experimental group using a face-to-face interview technique, and a patient introduction form will be administered by the researcher one day before surgery. The researcher will then provide patients with visual and verbal wound care training using the "Surgical Patient Wound Care Guide," and the educational materials will be provided. To assess the effectiveness of the training, a Knowledge Level Survey consisting of 10 true/false questions will be administered to patients on the third postoperative day. Two weeks after surgery, the Patient Follow-up Form, Self-Care Self-Efficacy Scale, and Quality of Healing Scale will be completed by phone.

The purpose of the study will be explained to the control group members, and a patient introduction form will be administered by the researcher using a face-to-face interview technique one day before surgery. On the third postoperative day, patients will be administered a Knowledge Level Questionnaire consisting of 10 true/false questions. Two weeks after surgery, the patient follow-up form, the Self-Care Self-Efficacy Scale, and the Quality of Recovery Scale will be completed by phone.

The researcher-created knowledge survey includes 10 true/false questions aimed at measuring the effectiveness of Surgical Patient Wound Care Education provided to patients. Each question will be evaluated out of 10. The lowest possible score is 0, and the highest is 100. Higher scores indicate higher knowledge levels. Expert opinions will be obtained from three faculty members with expertise in the field to assess the adequacy of the survey's content and scope.

The scale originally developed by Yu et al. to determine individuals' self-care self-efficacy levels was modified by Chica-Pérez et al. to assess self-care self-efficacy in older adults with chronic multimorbidity. The scale was designed as a 5-point Likert-type instrument ranging from "1 = I do not trust myself" to "5 = I trust myself a lot." It consists of 10 items in total. In their study, Chica-Pérez et al. reported Cronbach's alpha coefficients as 0.713 for the subscale "Self-Efficacy in Clinical Knowledge-Based Self-Care Behaviors," 0.822 for "Self-Efficacy in Self-Care," 0.881 for "Self-Efficacy in Monitoring Self-Care," and 0.878 for "Self-Efficacy in Self-Care Management." Chica-Pérez et al. stated that the minimum possible score is 10 and the maximum is 50, with higher scores indicating higher levels of self-efficacy in self-care.

The Quality of Recovery-15 (QoR-15) is a brief postoperative recovery scale developed and validated by Stark et al. in 2013. It is a shortened version of the QoR-40 scale. It is easier to use because it is shorter and can be completed in a shorter time. Like the QoR-40, it contains 15 questions that assess the patient's pain, physical comfort, physical independence, psychological support, and emotional state. The test results in a score between 0 and 150, with a higher score indicating better recovery quality. With the latest update, the minimal clinically important difference, that is, the lowest difference indicating a meaningful change, is 6 for the QoR-15.
