An Evaluation of a Clinical Care Pathway for the Management of Men With Nonorganic Erectile Dysfunction

Abstract

IntroductionThere exists little literature on the outcomes of the medical management of men with erectile dysfunction (ED) with no overt organic etiology. AimThis study was conducted to assess the outcomes of men with nonorganic ED treated medically. MethodsAll patients had normal hormone profiles and vascular assessment. All were given a trial of a phosphodiesterase type 5 inhibitor (PDE5i). If no improvement was experienced, intracavernosal injection (ICI) therapy was administered. All patients were encouraged to seek a consultation with a mental health professional. Main Outcome MeasurePatient demographics, medical comorbidities, hormone and hemodynamics assessments, and change in International Index of Erectile Function scores of patients were recorded. Results116 men with a mean age or 38 ± 19 (range 16−57) years were studied. 21% had mild ED, 47% had moderate ED, and 32% had severe ED. 21% had seen a psychiatrist. 81% of patients responded to PDE5i with a penetration hardness erection on follow-up (mean duration of 7 ± 3 months postcommencement of PDE5i). However, only 68% of these were capable of a consistently good response. The mean Erectile Function domain score on PDE5i for the entire group improved from 18 ± 11 to 22 ± 6 (P = .01), and for PDE5i responders it was 27 ± 4 (P < .001). 28% of men (22 PDE5i failures and 10 with a mixed response to PDE5i) attempted ICI, all obtaining consistently functional erections. At a mean time point of 11 ± 5 months, 83% of those responding to PDE5i had ceased using PDE5i due to a lack of need. 11% of those using ICI continued to use them 6 months after starting ICI; the remainder had been transitioned back to PDE5i. Of the 29 patients in the latter subgroup, 66% were no longer using PDE5i consistently due to a lack of need. Clinical ImplicationsNot all men with nonorganic ED respond to PDE5i initially and many of those who respond do so only intermittently; such patients are potentially curable, using erectogenic pharmacotherapy for erectile confidence restoration, most men are capable of being weaned from drug therapy. Strengths & LimitationsThe strengths of the study are the large number of patients and the use of serial validated instruments to assess erectile function outcomes. As a weakness, despite normal hormone and vascular assessments, the diagnosis of nonorganic ED is still a presumptive one. ConclusionMedical management of nonorganic ED utilizing the process of care model results in cure in a large proportion of such patients. The transient use of ICI in some patients permits successful PDE5i rechallenge.Jenkins LC, Hall M, Deveci S, et al.
