Purpose. To estimate the US prevalence of Peyronie's disease (PD) from patient-reported data and to identify diagnosis and treatment patterns. Methods. 11,420 US males ≥18 years old completed a brief web-based survey regarding the presence of PD, past treatments, and penile symptoms (Phase 1). Phase 1 respondents with PD diagnosis, history of treatment, or PD-related symptoms then completed a disease-specific survey (Phase 2). Results. Estimated prevalence of PD ranged from 0.5% (diagnosis of PD) to 13% (diagnosis, treatment, or penile symptoms). Thirty-six percent of Phase 2 participants reported that penile symptoms interfered with sexual activities. Of participants who sought treatment for penile symptoms (n = 128), 73% initially saw a primary care physician, 74% did not receive treatment from their first doctor, and 92% were not diagnosed with PD. Conclusions. PD may be underdiagnosed/undertreated in the US. Improved awareness is needed of PD symptoms and treatment options among health care professionals.

BackgroundThis large population-based study was conducted to estimate the prevalence of Dupuytren’s disease in US adults and describe associated treatment patterns.MethodsA total of 23,103 individuals from an Internet-based research panel representative of the US population completed a brief online survey designed to identify individuals with symptoms, diagnoses, and/or treatment experience indicative of Dupuytren’s disease (mean age = 50 years).ResultsThe prevalence of Dupuytren’s disease defined as a self-reported physician diagnosis and/or surgical treatment was estimated as 1% (95% CI = 0.8–1.2), but the estimated prevalence is much higher (7.3%) when including self-reported symptoms of ropelike growth or hard bumps on the hand. The annual incidence proportion was estimated at about 3 cases per 10,000 adults. A total of 326 participants who reported relevant Dupuytren’s symptoms, treatment, and/or diagnosis completed a more in-depth survey focusing on timing of medical treatments after first symptom noticed, description of functional impairment, treatment patterns, and family history. From the second survey, most patients who reported seeking treatment for hand symptoms initially saw a primary care physician, and the mean time from noticing the first hand symptom to seeing a doctor was 23.1 months. At their first doctor visit for hand symptoms, only 9% of patients received a diagnosis of Dupuytren’s disease and 48% were advised to “wait and see” or received no treatment.ConclusionsResults from the current study indicate a number of unmet medical needs, so strategies to raise physician awareness of disease symptoms and effective treatment options may be helpful.
