The Impact of Combined Written and Audio-Visual Information on Preoperative Anxiety Among Adult Undergoing Total Knee Replacement Surgery: A Quasi-Experimental Study

Background/Objectives: This study aimed to evaluate the effect of combined written and audio-visual preoperative education on reducing preoperative anxiety and information desire among adult patients undergoing total knee replacement surgery. Methods: A quasi-experimental model was used. The study was conducted in adult surgical wards of a Sultan Bin Abdul-Aziz Humanitarian City (SBAHC). One hundred thirty-six patients voluntarily participated in the study, 68 of them were in the Control group (CG) and 68 of them were in the Experimental Group (EG). While routine oral education only was given to CG, a combined written and audio-visual preoperative education was also provided to EG. Data were collected using a structured self-administered questionnaire (Arabic version of Amsterdam Preoperative Anxiety and Information Scale (APAIS)). The patients in both groups filled in the questionnaire and APAIS preoperatively at two time points before and after the intervention. Results: At baseline, the mean anxiety score was 12.90 ± 2.26 in the control group and 13.10 ± 1.86 in the experimental group (t = −0.58, p = 0.56). Similarly, the mean information desire score was 6.84 ± 1.43 in the control group and 7.16 ± 1.59 in the experimental group (t = −1.25, p = 0.21), indicating that the two groups were comparable prior to the intervention. After the intervention, the experimental group demonstrated significantly lower anxiety levels (9.26 ± 1.84) compared with the control group (11.49 ± 1.65) (t = 7.40, p < 0.001). Similarly, the information desire score was significantly lower in the experimental group (2.31 ± 0.58) than in the control group (5.46 ± 1.01) (t = 22.22, p < 0.001). Conclusions: A combined written and audio-visual preoperative education decreased preoperative anxiety and information desire among adult patients undergoing total knee replacement surgery.
