Determining the Effect of Education Given to Patients Undergoing Outpatient Anal Fistula Surgery

Sponsor: Muğla Sıtkı Koçman University

Summary

It is emphasized that discharge education should shift from traditional healthcare provider-centered, one-way education to patient-centered education based on patient-care provider interaction to ensure patients' active participation in their own care, adherence to the recommended treatment plan, and maintenance of surgical success after outpatient anal fistula surgery. In this context, it is suggested that an effective education method such as teach-back can be used in clinical settings to teach patients complex health information and facilitate their understanding of discharge education. While studies exist in the literature evaluating the impact of health literacy after general surgery, no studies have been found specifically evaluating health literacy and discharge education for anal fistula surgery. Furthermore, it is emphasized that further research is needed to improve the quality of postoperative care after anal fistula surgery and to better understand the factors contributing to unplanned hospital returns. Based on this need, this study is a randomized controlled trial with a pretest and posttest approach aimed at determining the effect of teach-back-based discharge education on hospital readmission and patient satisfaction in outpatient anal fistula surgery patients. The study sample was calculated as a total of 68 people, 34 in each group, based on a power analysis performed with the GPower 3.1. 9.7 program, using a type 1 error of 0.05, a type 2 error of 0.20, and an effect size of 0.70 to determine the difference in measurements between the groups. Considering the possible attrition in the study, the sample size was increased by 10%, and a total of 76 people, 38 in each group, were planned to be included in the study. Following Ethics Committee approval and institutional permissions, the study data will be collected using the Individual Identification Form, Health Literacy Scale, Anal Fistula Surgery Discharge Education Knowledge Test, Discharge Satisfaction Scale, and Post-Discharge Follow-up Form, from patients scheduled for and undergoing outpatient anal fistula surgery at Muğla Training and Research Hospital between November 15, 2025, and January 30, 2027. The research will be conducted in three phases: the development of the education brochure and knowledge test, and the preoperative and postoperative phases. The "Anal Fistula Surgery Discharge Education Knowledge Test" was developed to assess patients' knowledge of anal fistula and its care. The "Anal Fistula Surgery Discharge Education Patient Booklet" was developed by the researchers using literature review and consultation with a General Surgery Specialist specializing in anal fistulas to provide specific training on anal fistula surgery and postoperative care. These were then sent to specialists for expert opinion. All patients presenting to the General Surgery Outpatient Clinic for anal fistula surgery who meet the inclusion criteria will be interviewed face-to-face before surgery to be informed about the study. Patients who agree to participate will be asked to sign a consent form. Because outpatient surgeries involve admission and discharge within 24 hours, and patients arrive at the Proctology Unit on the day of surgery, all patients will be summoned to the General Surgery Outpatient Clinic the day before surgery and will complete the "Individual Identification Form," "Health Literacy Scale," and "Anal Fistula Surgery Discharge Education Knowledge Test." Patients will be assigned to the intervention (discharge education via teach-back) and control groups using a block randomization table based on their order of admission to the Proctology Unit for the surgical procedure. Patients in the intervention group will receive discharge education via teach-back using the "Anal Fistula Surgery Discharge Education Patient Booklet." Education will continue until the patient accurately recounts the information to the principal investigator and is confident that the patient has understood the instruction correctly. The control group will receive standard patient education in the clinic and will not receive any intervention. Postoperatively, all patients in both groups will complete the "Anal Fistula Surgery Discharge Education Knowledge Test" post-test and the Discharge Education Satisfaction Scale before being discharged from the unit. Patients in both groups will be contacted weekly for 30 days to monitor their progress. Because the study will provide training, blinding of the assessments will not be possible.
