AimTo investigate the effect of preadmission education given to laparoscopic sleeve gastrectomy patients on preoperative and postoperative anxiety, postoperative pain, and patient vital signs.MethodsThe study was designed as randomized, controlled, experimental, and single-blind. This study was conducted with 68 patients who met the inclusion criteria and underwent laparoscopic sleeve gastrectomy in the general surgery clinic of a university hospital between December 2022 and October 2023. Data were collected using the 'Perioperative Form,' 'Visual Analog Scale,' and 'State Anxiety Scale I-II.' Intervention group patients were informed and educated about the surgical process in the outpatient clinic. The anxiety levels of all patients were determined with the State Anxiety Scale the day before surgery. In the postoperative period, vital signs (once), anxiety (on the first day after surgery), and pain levels (eight times during 48 h) were measured.ResultsIn the analysis between the groups, the difference between the duration of postoperative hospital stay (p = 0.007), pain (p = 0.000 for all measured), and anxiety levels (p = 0.000) was statistically significant. There were also significant differences in the diastolic blood pressure (p = 0.007), body temperature (p = 0.000), and saturation values (p = 0.000). Patients' readiness level for surgery was the most influential factor in postoperative pain levels (p = 0.000).ConclusionThe education given to the patients before hospitalization decreased preoperative and postoperative anxiety levels, postoperative hospital stay and pain levels, and positively affected diastolic blood pressure, body temperature and saturation levels. One-to-one education given to patients in the outpatient clinic also contributes positively to their readiness for surgery. This study provides valuable evidence to the wider global clinical community by demonstrating the important benefits of preadmission education for patients undergoing bariatric surgery. Implementation of similar educational interventions in diverse healthcare settings worldwide may lead to increased postoperative recovery and improved overall patient well-being after bariatric surgery.© 2024 The Author(s).
