Spinal Stenosis Patients' Visual and Verbal Description of the Comprehension of Their Surgery

BACKGROUND: Spine surgery patients have difficulty comprehending the patient education aimed at preparing for surgery. PURPOSE: To assess the effect of a specific preoperative education approach (Knowledge Test Feedback Intervention, KTFI) on patients' verbal and visual understanding of their surgery. METHODS: In this randomized controlled trial, the intervention group (n = 50) went through the KTFI and routine education, whereas the control group (n = 50) received only routine patient education. Written description of the surgical procedure and drawing of incision were used as outcome measures at baseline, at hospitalization, at discharge, and 3 and 6 months after surgery. RESULTS: At baseline, half of the participants showed verbal and visual understanding of their surgery. During follow-up, understanding improved significantly with no statistically significant differences between the groups. CONCLUSION: Spinal stenosis patients' understanding of their surgical procedure is imperfect. Patient educators need to ensure patient learning by evaluating comprehension outcomes.
