An assessment of patient-reported outcomes for men with erectile dysfunction: Pfizer's perspective

Abstract

Patient-reported outcomes (PROs) for men with erectile dysfunction (ED) have blossomed in the published literature and at professional conferences. These outcomes have been central to study the science of ED itself and to evaluate efficacy of treatment for men with ED. In this review article we highlight and distinguish among seven key PROs: the International Index of Erectile Function, for sexual function including erectile function; the Sexual Health Inventory for Men (SHIM), for diagnosis of ED; the Quality of Erection Questionnaire, for satisfaction with quality of erections; the Erectile Dysfunction Inventory of Treatment Satisfaction, for personal evaluation of treatment received; the Self-Esteem And Relationship questionnaire, for emotional well-being; the Erection Hardness Score (EHS), for targeting erection hardness and the Sexual Experience Questionnaire, for erection (both function and quality), individual satisfaction and couples satisfaction. Depending on the purpose of the investigation, all seven PROs have merit for use in clinical trials and at least deserve consideration in clinical practice. The SHIM and the EHS, given their aims and brevity, deserve special consideration in clinical practice. As a unit these seven PROs complement and supplement each other. Which ones to choose in a particular undertaking depends on the objective or purpose of a given study. These PROs acknowledge that sexual dysfunction and its treatment have multiple dimensions. Each of these instruments represents a significant contribution to sexual medicine research and, when used judiciously and appropriately, can help to provide optimal patient care and management.
