Increased preoperative knowledge reduces surgery-related anxiety: a randomised clinical trial in 100 spinal stenosis patients.
European Spine Journal 2017 October
PURPOSE: To assess the impact of preoperative knowledge on anxiety, health-related quality of life (HRQoL), disability, and pain in surgically treated spinal stenosis patients.
METHODS: One hundred patients were randomised into an intervention group (IG, n = 50) or control group (CG, n = 50). Both groups received routine preoperative patient education. IG additionally underwent a feedback session based on a knowledge test. Primary outcome measure was anxiety at the time of surgery. HRQoL, disability, and pain constituted the secondary outcome measures during a 6-month follow-up.
RESULTS: In IG, a significant reduction in anxiety was noted after the intervention, whereas in CG, anxiety reduced only after the surgery. In both groups, a significant improvement in HRQoL, disability, and pain was noticed at the 6-month follow-up, but there were no between-group differences.
CONCLUSIONS: Higher knowledge level may reduce preoperative anxiety but does not seem to affect the self-reported clinical outcomes of surgery.
