(PNM-41) Impact of physician assistance on IIEF-5 classification in erectile dysfunction assessment

Abstract Introduction The International Index of Erectile Function-5 (IIEF-5) is widely used for Erectile Dysfunction (ED) evaluation but, patient self-reporting may introduce inaccuracies responses. This study compares self-administered versus urologist-assisted IIEF-5 results in 121 patients with sexual complaints. Objective To evaluate how physician guidance affects ED severity classification using IIEF-5 compare to patients self reporting ED. Material We included in this stydy 121 men with ED complaints. The patients with ages between 42 to 64 years old, from January 2023 to January 2025. In Phase 1: self reported IIEF-5, before medical consultation. Phase 2, after 7 to 14 days, patients come back with sample analysis and did it with urologist assisted. Results This analysis showed that (27/121) patients were reclassifield. The comparative analysis of self-reported versus urologist-assisted IIEF-5 assessments revealed significant diferences in classification among these 121 ED patients. Initial self-reporting showed a predominance of mild–moderate ED (43.0%, n = 52), followed by moderate ED (32.2%, n = 39), with no patients self-classifying as having “NO ED”. However, urologist assistance substantially altered this distribution: 16 patients (13,20%) shifted from moderate to milder. Other 6 patients (5,0%) moved from mild–moderate to mild classification. And 12 previoulsy diagnosed ED patients (9.9%) were reclassifield as having “NO ED.” Conclusion Urologist assistance significantly alters IIEF-5 classification, particularly reducing false-positive ED diagnoses. Clinician involvement improves accuracy but requires additional resources. Self-administered IIEF-5 should be interpreted with caution in borderline cases. Financing No conflict’.
