An important question regarding the use of this survey is the change in score that is perceptible to patients. To date, these thresholds have not been defined. In order to best use the EPIC survey in outcomes research, changes in scores that are reliably perceptible and clinically significant must be established. The present study correlates changes in the EPIC urinary scores with the patient's subjective assessment of their change in urinary symptoms. METHODS All men undergoing prostate brachytherapy at a single institution completed an EPIC survey pre-operatively and at all follow up visits. At each follow-up visit, patients were also asked to describe their urinary symptoms as much better, slightly better, about the same, slightly worse, or much worse when compared to their last visit. The numerical change in the EPIC score was correlated with the patient's reported subjective degree of change in their urinary symptoms. At each post-operative visit, patients were also asked to report via a yes or no answer whether their urinary symptoms had returned to their pre-operative baseline. RESULTS The study included 252 men who completed 587 surveys. The mean pre-operative EPIC urinary summary score was 86.9 (scale 0–100). Mean change in the EPIC urinary summary score was a decrease of 25.8 for men who described their urinary symptoms as “much worse”, a decrease of 13.2 for men “slightly worse,” an increase of 0.32 for men “about the same,” an increase of 4.3 for men “slightly better,” and an increase 11.0 for men “much better.” Urinary subscales followed the same pattern with the greatest magnitude of change in the bother and irritative/obstructive subscales and the smallest magnitude of change in the incontinence subscale. Patients who answered “yes” to the question of whether their symptoms were back to pre-operative baseline had a mean change of 0.03 in their EPIC urinary summary score when compared to their pre-operative baseline. CONCLUSIONS This study correlates numerical changes in the EPIC urinary summary and subscale scores with the patient's perception of clinical change. The results will provide guidelines for investigators using the EPIC survey as an outcome measure and help in reconciling statistically significant changes in EPIC scores with their clinical significance. © 2011 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 185Issue 4SApril 2011Page: e254 Advertisement Copyright & Permissions© 2011 by American Urological Association Education and Research, Inc.MetricsAuthor Information Robert Turner Pittsburgh, PA More articles by this author Jeffrey Tomaszewski Pittsburgh, PA More articles by this author Ryan Smith Pittsburgh, PA More articles by this author Sunil Beriwal Pittsburgh, PA More articles by this author Ronald Benoit Pittsburgh, PA More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
