Interpreting Patient Reported Urinary and Sexual Function Outcomes across Multiple Validated Instruments.

ABSTRACT:

Purpose

Comparing patient reported outcomes such as urinary and erectile function across institutions is critical for prostate cancer research and quality assurance.

Materials and methods

Patient reported data on urinary and sexual function were collected on 1,284 men with localized prostate cancer using the EPIC-26 (Expanded Prostate Index Composite), PCI (UCLA Prostate Cancer Index), SHIM (Sexual Health Inventory for Men) and I-PSS (International Prostate Symptom Scale) questionnaires.
